Because of various models of mobile phone attached to different causes, charger socket between each mobile phone charger not common. When the user mobile phone chargers damage or loss, cannot be repaired or buy less charger, cannot use the same key. Universal charger manufacturers see such opportunities, development and production of the mobile phone’s battery charger, the charger because of its small volume, convenient to carry, simple operation, low price, suitable for machine, deeply user’s welcome. Here in shenzhen Alexander tong industrial Co., LTD production of universal tong S538 universal charger for example, this paper introduces the working principle and maintenance method. The charger, in the market share and no random incidental to bring some maintenance diagram of difficulty, according to the work principle of surveying and mapping object, see figure for maintenance.
Universal tong S538 universal charger on exterior design is unique, the panel using transparent plastic production of elliptic clip, transparent plastic panel two fixed distance adjustable stainless steel electrode for charging reed. The rear side panel of one polarity switch switch (test) and the four lights, according to the state of user can adjust the charger electrode distance and the output voltage polarity, and can be easily seen by state indicator of charging battery.
A, principle of work
The charger circuit consists mainly of oscillating circuit, charging circuit, protect circuit, the input voltage AC220V, 50/60Hz, 40mA, output voltage DC4.2 V, output current 150mA in 180mA ~. In charge, first, connect to the rechargeable battery charger panel on whether the test indicator light? If the bright, correct polarity, can switch on the power, Otherwise, the battery charger output voltage polarity and the polarity is opposite, then need to click the polarity switch AN1 (test button). Specific circuit principle as follows.
1 oscillating circuit
This circuit consists mainly of transistor VT2 and switch transformer T1 etc. Switch on the power, communication 220V diode rectifier, VD2 half wave formed around run at 100V dc voltage. The voltage transformer by switching the primary windings 1 T added to transistor VT2 c extremely, meanwhile, the voltage by starting resistance is the R4 VT2 is provided a b bias voltage, make VT2 conduction. At this time, the transistor VT2 is composed of T1 and switch transformer intermittent oscillating circuit start working, switch transformer T 1-1 in current through the primary windings. Because of the positive feedback effect, in transformer windings of the 2-1 the voltage induced by the feedback resistance and capacitance R1 added C1, make the b VT2 transistor VT2 b very current flow, quick in saturated zone. With the capacitance C1 ends, voltage VT1 b voltage gradually lowered, make triode VT2 is gradually saturated zone, its from beginning to reduce collector current transformer T, 1-1 in the primary windings of flux also began to decrease. In transformer windings of the 2-1, the negative feedback voltage induction deadline, completing a rapid VT2 oscillation periods. During the globe in VT2 into the transformer windings is 1-3 induced a 5.5 V ac voltage, or as the recharging voltage level.
2 charging circuit
This circuit consists mainly of a RuanSu seal block IC1 (YLT539) and the transistor VT3 etc. From the 1-3 transformer windings induction of ac voltage 5.5 V VD3 diode rectifier, filter, output capacitance C3 a dc voltage (about 850 V), the voltage no-load part to VT3 triode e extremely, Another part of RuanSu to block sealing IC1 YLT539 (1), provide the job power. Integrated block IC1 job power after the start work, in its eight feet output low level, VT3 triode charging pulse conduction, dc voltage began to 8.5 V battery charging E.
As for the rechargeable battery E, 4.2 V lower voltage is the voltage resistance by sampling R11 R12 pressure, and add to the integration of six feet IC1 block, the lower voltage reference voltage IC1 integrated blocks the internal integrated blocks, 8 feet IC1 output level is lower, the transistor VT3 b extremely potential also lower the flux, the guide, dc voltage (8.5 V) by switching to cell polarity S1 fast charging E. Because of the integrated block IC1 2, 3, 4 feet and capacitance C4 common component oscillating circuit, the two feet of the output pulse vibration resistance to battery indicator R16 LED1 (green), the positive anode block received eight feet IC1. The battery just answer one circuit IC1, integrated block 8 feet output level is lower, the battery indicator light LED1 flashing. With rechargeable battery charging prolonged, the voltage, integrated block slowly IC1 eight feet slowly rising, charging output voltage LED1 lights flashing light become weak gradually.
When the battery E slowly when filling to 4.2 V, integrated block 6 feet IC1 also reached its internal potential reference voltage 1.8 V. At this time, the integrated circuit IC1 piece inside, make its eight feet moves voltage output level, VT3 triode, rechargeable lights no deadline LED1 flashing lights, and extinguished by LED2 (green) destroyed brighten.
3 voltage protection circuit
This circuit consists mainly of transistor VT1, diode VDZ1 etc.
Over-voltage protection: when the output voltage rises, in the 2-1 transformer windings of the inductive voltage feedback, capacitance increases by charging pressure. C2 When the capacitor voltage exceed voltage at C2 VDZ1 diode, the voltage stabilizing conduction, VDZ1 diode breakdown voltage, the base of transistor VT2 is low, make its conduction time shorten or quickly, the switch by coupling, transformer T1 secondary output voltage. Conversely, the output voltage, thus ensuring stable output voltage.
Over-current protection in the switch on the power, or when certain causes a moment when the current transistor VT2 in R5, R6, the pressure drop is big, make the over-current protection tube, VT1 conduction deadline, thus effectively prevent VT2 VT1 switch for current impulse and damage. Also on the resistance of the pressure drop, R6 make voltage capacitance C2 ends, over-current protection principle, process and the same voltage here not repeated. VT1 triode tube is over-current protection, R6 is VT2 R5, over-current protection of sampling.
Second, the common breakdown maintenance
Ex.1: connected with rechargeable batteries and power supply, power LED3 indicator lights and TEST pwi LED4 TEST bright, and LED1 charging and LED2 not bright lights, no voltage output, cannot give the battery.
Analysis: the fault is access oscillating circuit switch without work charger. In the actual repair process, found switch pipe resistance and VT2 is most damage R6. Normally, battery recharging circuit E working voltage, low probability of its component damage is not great, namely after subprime T1 transformer switch is the probability of damaged circuits.
Example 2: connected with rechargeable batteries and power supply, each state indicator shows normal, but is not charged rechargeable electric or longer.
Analysis: the fault is overhaul VT3 triode 8550 (with normal tube), after the change, can remove the faults. If VT3 triode, reoccupy table test capacitance C3 (100 mu F / 16V) ends in dc voltage, normal 8.5 V. If the voltage is normal, should check R7 resistance, integrated blocks or IC1 IC1 integrated blocks the normal parameters such as schedule. If the voltage, measure voltage transformer switch T1 subprime, normal in exchange 5.5 V. If the voltage is normal, capacitance C3 or rectifier diode VD3 damage, If the voltage transformer, should check switch before each element and its magnitude T1.
When there is no external power source conditions, if the working condition of PCMCIA groove, suggest the CARDS you remove the card so as to prolong the life time of the battery.
At room temperature (20-30 degrees) for the most appropriate battery working temperature, the temperature too high or too low operating environment will reduce battery time.
In may provide stable power supply environment using a notebook computer batteries, remove battery life can be extended by is not correct. HuaShuo notebook computer is concerned, when the battery power after the battery charging full recharging circuit will be closed, so it won’t happen overcharge phenomenon.
Suggestions for three months on average battery power correction action.
Minimize the use of the battery
The battery charging and discharging number directly related to the life, every time, batteries charging to move a step. Suggest you try to use external power supply,
Use external power supply should be taken down.
Some users often times in a day, and inserted power laptop battery, such doing, with more damage to the battery. Because each time the external power source to access to the battery, the battery is a natural SheShou.
After the power used for recharging and avoid charging for a long time
Regardless of your laptop or using lithium electricity nimh electricity, must be used after the battery charging power (1%), this is the best way to avoid memory effects. Li-ion battery will also have memory effects, but its memory effects than nimh smaller.
Peacetime use attention
In peacetime use to prevent insolation, prevent moisture, prevent erosion and avoid chemical liquid battery contacts with metal contact, etc.
When faced with:
Computers can correct boot disk boot, after finding time not correct, CMOS setup cannot save phenomena, can check whether the motherboard CMOS jumpers set to remove “CLEAR” option (usually 2-3), and if so, please will jump line “that” option (usually 1-2) and then reset.
If not, they jump line CMOS mistake probably because the mainboard batteries or damage caused by a lack of battery voltage, please change the mainboard battery try.
Generally speaking, the assembly of 3 years, 6 years of original.
The average price of $3-8. The diameter of the battery are motherboard according to the battery, 20 mm thickness into “CR2016″ CR2025 “CR2032″ several models. Almost all the mainboard batteries are CR2032…
On the mainboard battery life depends on the quality of battery, the battery in general users can choose to SONY.
Battery on condition is in charge at the computer shutdown, after the BIOS to discharge the related information in order to keep the BIOS (for example: the clock). This discharge is weak, so, if no damage to the battery is not meeting didn’t point.
If the battery damage, or not, the most direct normal use can be found where the problem is no longer operating system clock, if damaged, turning the BIOS displays relevant information, then the error of the computer will not enter operating system.
Experienced users know battery charge is the largest consumers of electric bicycle, so users are very concerned prolong the life of the battery. First to assume no problem, if users charger correct use of the battery life is very important. Use the battery precautions are as follows:
1, do not replace charger, don’t remove the speed controller.
Each manufacturer charger generally have no master individual needs, in the time don’t replace charger. If XuHang mileage requirements, and equipped with different charging to multiple charger, took up the charger adopts during charging the battery charger, and adding the charger using original evening. Remove the controller can improve the speed limit, though some of the speed of a car, but can reduce the safety car outside, also can reduce battery life.
2 and protect the charger.
General instructions above all about protecting the charger. Many users have read the instructions of the habit, but just remember after problems often find instruction, often first read the instruction, so it is very necessary. In order to reduce cost, now the charger is basically do not high resistance, so that the vibration, the charger general design on the trunk of electric bicycle and baby. Special circumstances, must want to move, also want to take charge for foam packaging, prevent the occurrence of vibration. Many charger, its internal after vibration through the potentiometer will drift, make whole parameter drift, cause for charging status is not normal. Also note the time to keep is charging the battery charger, otherwise not only affect ventilated, charger could happen hot charging and drift. This form of batteries. Therefore, protect the charger is very important.
3, charging every day.
Even if you XuHang ability request is not long, a electricity can use 2 to 3 days, but still suggest you every day, so make battery charging in shallow circulating state, extend battery life will be. Some of the early use mobile phone users think is best used basic battery recharging after, this view is incorrect, the memory of lead-acid batteries less intense benefit. Often put to finish electric battery life influence is bigger. Most in the indicator light changes charger, battery charged instructions after filling into electricity may be 97% ~ 99%. Although only 1% ~ 3% owed rechargeable battery, the influence of XuHang ability, but also can be formed, so the battery charging owe accumulated with electric light changes as soon as possible after or continue to restrain battery charging, float sulfide is good.
4 and timely charging.
After discharge battery began vulcanization process, 12 hours in the beginning, there is an obvious sulfide. Timely charging, can remove not serious vulcanization, if not charging, these vulcanization crystallization will gather and gradually formed a bulky crystallization, general charger for these bulky crystallization is helpless, and will gradually formed battery capacity drops, shorten the life of the battery. So, besides daily charge, but also pay attention to the outside, after using the charging, early as possible so that the battery in full status.
5 and regular deep discharge.
Batteries are a deep discharge also regularly to activate “battery”, the capacity of the battery can be slightly ascension. Generally, the method is a regular for battery completely discharge. To completely discharge method is in smooth surfaces under the condition of normal load bike to the first voltage protection. Note, we emphasize the first voltage protection. In the first battery voltage protection, battery through after a period of time, the voltage will rise, and returned to the voltage state, if use the battery, the battery damage. In complete discharge completely, battery is fully charged on. Feel battery capacity to improve.
6 and develop the good habit of saving some.
Use glide. If possible, the downhill slide slowdown in advance by electricity. When the traffic lights will meet in advance into the taxi, minimize the brake. A friend told me, he is rather than a bay will reduce a brake, it is reasonable.
Start-up time, had better add, not only can improve bike, but also can reduce starting velocity of battery power loss and damage to life.
7, pay attention to the environment of charging.
The best environment temperature is charge of 25 degrees Celsius. Now most charger not adapt to the environment temperature automatic control system, so most charger is designed in accordance with the environmental temperature 25 degrees Celsius, under the condition of 25 degrees Celsius in charge. Otherwise, it will inevitably occur in winter and summer owe the charging charging problems. But the environment temperature in 25 degrees Celsius, less time must have summer charging battery. Winter owe Most families are in now, so indoor temperature-adjusting, charging the battery, the best arrangement is ventilated and chargers and tempering in the environment.
Note the battery in winter in the north is outdoor temperature condition into warm indoor, cell surface appear frost condensation. In order to avoid any cause of frosting on batteries battery leakage, should rise to temperature with indoor temperature and dry again after charging.
8 and make full use of service conditions
Many electric bicycle dealers can provide repair and maintenance of the battery service, should make full use of these services. Some brands of electric bicycle for battery maintenance. Such as: the battery for preventive maintenance, can reduce the damage to the battery. Battery charged state repair can relieve “battery” failure, but behind these to the maintenance ability with the dealer is easy. For loss, when the battery capacity is more than 70% of the filling water when the battery capacity 40% of the effect is better. Even some brand products are put forward: the stipulated time not to give up the cells repair warranty period. Make consumers should not happen by losses. Therefore, consumers should fully utilize the conditions extend battery overhaul increases the life of the battery.
Through these methods, the user can extend the life of the battery. Some users XuHang mileage is short, the life of the battery is relatively long, some problems are relatively difficult to find. Therefore, the article 4 to say “deep discharge” is a problem that battery, don’t wait for the serious problem of batteries when they handle hard.
A, Nickel cadmium battery (Nickel – Cadmiun Batteries)
1 nickel cadmium battery can repeat 500 times more charge-discharge, very economy.
2 for small and large internal discharge, and when it changes when discharging voltage, small as dc power is a kind of excellent quality of the battery,
3 because of the sealed, it will not have electrolyte leakage phenomenon, also don’t need to supplement electrolyte,
4 and other types of cells, in contrast, nickel cadmium battery charging resistance or pass electricity, easy to operate,
5 long placed next to performance degradation, when electricity is filled out when the original properties,
6. Can be used in a wide range of temperature range,
7 just because it USES metal containers, and have strong mechanical,
8. Nickel cadmium battery in very strict quality management is manufactured, have very good quality of rice.
Second, nickel cadmium battery discharge properties
1. According to the discharge current discharging voltage difference in how some 1.2 V is around,
2. Ah, the capacity of the battery in mAh units,
3 when the discharge end to discharge the limit when called “discharge termination voltage,” nickel cadmium battery discharge termination voltage 1.0 V/cell,
4 use temperature range – 20 ° ~ 60 degrees, in this range can undertake discharging.
Third, preservation of attention
1 in – 30 degrees c ~ 50 degrees Celsius temperature range, but if it is kept in a long time, please put the case in 35 degrees below preservation,
2 for charging status or discharge of preservation is possible, but compared to discharge capacity can be easily earlier reply and activated,
3 when the battery in long placed before use, must be completely charge before use.
Four, nickel cadmium battery memory effects (effect) with memory
When the nickel cadmium battery repeat after several times of low capacity after, if must do a relatively large discharge battery will not when, this kind of situation we called “memory effects”. Memory effects may be nickel cadmium battery in the most easily misunderstood. High voltage is set to terminate discharge the VCR, with the lower voltage is used, on the surface, but seems as low voltage discharge is 1 ~ 2 times by the discharge completely and solve this phenomenon. Suggestions after ten times a discharge battery, in order to prevent the suggestion.
Lithium batteries,
A, Lithium Ion Lithium Battery (a) features:
1. With high density and high capacity than nickel cadmium battery energy for its volume, weight energy density of 1.5 times for 2 times,
2 high voltage, the average voltage is 3.6 V, nickel cadmium battery nimh batteries, three times (nickel cadmium, nimh batteries voltage of 1.2 V),
3 the use of voltage and high capacity; plain,
4 the load characteristics, can discharge 2C,
5 the extensive use of the temperature – 200c.best ~ 60 ° c
6 good life, through the charging and discharging after discharge capacity of 500 times at least 70%.
Ni-mh battery and lithium battery difference:
A weight
With each unit cell voltage, and nickel cadmium nimh is 1.2 V, and lithium battery is 3.6 V, lithium battery voltage is the other two 3 times. And the same type of lithium batteries battery weight with nickel cadmium battery almost equal, and nickel nimh batteries are heavier. That every cell itself, but the lithium battery weight by 3.6 V output voltage, high voltage under the condition of the same number of individual cells that gives can reduce one-third and make after battery weight and volume decreases.
Second, the memory effects
With ni-cd battery are the same memory effects. Therefore, the regular discharge management is also required. This regular discharge by fuzzy condition belongs to, even some incorrect knowledge under each discharge or use discharge (several times after discharge for company’s varies) this complicated discharge management in use when nimh batteries is inevitable. Relative of lithium battery for no memory effect, because of the very convenient in use. It is not how much heed residual voltage directly, can undertake rechargeable battery can shorten the time nature.
Third, self-discharge rate
Nickel cadmium battery for 15-30% (month). Ni-mh battery for 25 ~ 35% (month), lithium battery for 2 ~ 5 (month). Above the nimh batteries, and is the largest self-discharge lithium batteries with other two kinds of special than batteries discharge rate is extremely low.
Four, charging ways
Ni-mh battery and lithium battery charging can resistance. Therefore, the current nimh batteries to PICK the battery recharging voltage control way in how to reach the highest, stop charging for best charging ways. But while using lithium battery voltage, current, the best way to recharge, if the nickel cadmium battery charger – DV control for ni-mh battery charging words and lithium batteries.
Error: laptops to buy back again to activate battery charging and discharging three times.
Unless you buy laptop is more than one year, the product inventory or need not do so, because of the battery factory now in the core, and have been activated when the core notebook batteries into when once again to activate the inspection, so you take the battery is activated, the three times, the process of charging and discharging is meaningless increase battery depletion. Error: the first charge must be charged enough for 12 hours.
Error: the first charge must be charged enough for 12 hours
This for those early no batteries control circuit of the machine is applicable nimh batteries, but for now, an intelligent control circuit of the laptop battery charge is a joke, when the notebook computer batteries charging current with, will be cut off, even if you continue to filling 120 hours, the state has also won’t have any change, generally speaking, even the slowest charging machine, 6 hours, completely filled with “charge” is just wasting your time. But when the new machine is to get the power should be shining recharging.
Error: battery needs regular correction, once a month were completely.
For the strong memory effects, this is the nimh batteries must work, but for lithium batteries, this cycle is too often, though not completely eliminate lithium batteries, but has memory effects greatly abate the memory effect, if you use the battery is frequent, so you should be discharged to a lower (about 10-15%), but if the discharge recharging the machine can’t open (0-1), is to have greater damage of lithium batteries, generally speaking the depth discharge every 2 months to do this operation. If you rarely used batteries, so just once every 3 months of this operation.
Four: calibration error can ascend battery capacity
When the battery is called correction, the actual capacity and control circuit of the record for different capacity battery charging and discharging operations, a depth to control circuit, and make record close to the actual situation of the battery, the battery is an expression of the real capacity and non-ascending capacity, here is the key factor of the battery, the battery actual capacity than the actual capacity, if the control circuit of the record, the capacity of the battery capacity calibration can look, if increase battery capacity than the actual control circuit of the record low of capacity, correction will reduce battery capacity, it also seems to correction is many people argue, please remember that the real correction is a battery capacity, eliminate battery and deviation between the control circuit and the capacity is displayed as will increase or decrease, this is the state battery itself instead of your calibration of the decision. Probably because of the depth of the battery when correcting, instead of discharge capacity drops greatly.
Myth 5.not: compatible charger can also use
The notebook computer power far outweigh the mobile phone, in the most extreme cases, power supply for battery and to cope with the machine run at full speed for power supply, notebook computer is not compatible with each type of battery charger, because of voltage, current, or interface are different, can be in a variety of universal notebook “compatible charger” probably even more expensive than the original charger, even the same interface, if the voltage and current under the nominal value, machine working at the machine when battery may be unable to gain enough for the battery charging electric current, the damage is great. If the voltage and current under nominal values, even find too many fundamental unbootable or can boot cannot charge, so choose to choose the best of power and the same, original couldn’t find words, please pay attention to the voltage and current must conform to the machine, with the nominal values of different products, but generally the same interface voltages and currents may be different, it must pay attention!
Error: full battery electric (or need) save electric light
Both full or light, it is incorrect, light electricity for long-term preservation will lose activity core, even control circuit protection self-locking and can’t use, full of electricity for long-term preservation will bring safe hidden trouble, the most ideal method is about 40% to discharge and preservation, lithium battery moist and fear, therefore, should be high in cool and dry place, but may not be too low temperature, otherwise will greatly reduce the capacity of about 20 degrees Celsius temperature preservation is the ideal.
Seven: the battery and error can still change core
Many of the battery is such a change of deadly, manufacturers seem expected someone will do so, many brand notebook batteries design are locking function, once the core from control circuit, circuit entered self-locking condition, only use a specific method can solve, before this control circuit will not work, namely battery core notebook batteries, equivalent to scrap the dry batteries can not change, if you want to change, please remember to find core of battery maintenance companies to settle in fencing, his efforts, the void after failure of depression and depressed is the worst.
After eight: 99 misunderstanding, continue to less than 100% charged rechargeable would explode
The laptop battery explosion is almost no chance at a high fever, caused by melting, but rarely shell caused by fire, released a few accident is due to the fact that the production process, when in use to cause a short-circuit, even the most short circuit will be in the battery protection circuit disconnected from greater harm circuit, unless it is in the core short-circuit protection circuit before. It is so many things in the mobile phone battery, ultimately or the quality problem, mobile phones have plenty of inferior assembly, notebook computer batteries almost never such a battery, because no sale which type of ownership is compatible to produce batteries.
1, invisible battery back-up
Your cell phone battery shortage, in order to make it can continue to use, according to * imports, # key reboot, after the start, you will find the power increased by 50%. This part of the hidden spare power with you must charge
Again, when the battery, the battery back-up invisible also charging, next time again low power can use this method. Know the emergency power shortage is very useful if mobile phones.
2, the handset battery don’t wait no electricity charge.
We will have a general idea of the mobile phone battery power is to put all finished recharging better basically is right, because we use rechargeable batteries before most nimh batteries are (NiH), and the so-called nimh batteries are put through memory effects if not words will lead to more electricity filling rapidly shrinking battery life. Therefore, we will use the last drop start charging electricity. But now, phone and general product with lithium most IA (Li) battery, and lithium battery is no memory effects. If you still wait all finished with electricity after filling words can make instead of lithium battery internal chemical reaction and life can reduce. The best way is to have it kept charging anytime, so best full lattice of your battery can be used for long. This is the manufacturer, and gets the message itself and testing.
3, a mobile phone with don’t use reception and a full only when compared to launch strength unexpectedly are more than 1,000 times as. So… Always speak phone… Should notice oh… @0@, from a mobile operators there yesterday won a very important message, that is when you find your mobile phone reception strength only one case, would rather talk or switch to hold a public phone. Just don’t talking, still, deep, stop, endless… Why? Everybody knows the phone is always let people worry about electromagnetic. And mobile phones to reception in poor regions can still keep quite call quality
The electromagnetic wave, will strengthen mobile launch reception. When a full and only when compared to launch strength unexpectedly are more than 1,000 times as high strength. Electromagnetic 0.6 W (watts) 0.6 W how strong? I can’t describe it to your head will have anything bad influence, but can change to compare two examples:
2 very few people know mobile 4 big hidden function! ZT –
1) diameter is about 4 centimeter horn of small radio the largest open and then stick in the ear, that the noise is generally energy, less than 0.5 w. w. 0.25.
2) finger on the output of the laser light intensity 0.1 W (equivalent to the front lines? D fibre optic network energy) seconds you will have stings feeling, you can long endure the above two kinds of situation?
How can you confirm that the electromagnetic wave to 0.6 W in your ears will fine?
How to keep the cell phone battery back
When your cell phone battery short (memory effects or aging), whether you’ll buy a battery to replace?
The next time you encounter this kind of situation when please save you money, tell you a very effective method might as well try:
The 1) battery again into the plastic wrap paper wrapping package well into the freezer days (newspapers can absorb excess moisture)
After three days at 2) removed down days
3) days after the battery charging and fill in mobile phone wrapped test (estimate can save 80-90%),
Lithium ion battery and cadium battery completely different. As long as you convenient, you can always for lithium ion battery, altogether like that, in order to make cadium battery performance will be the maximum discharge completely, must be to charge and must be filled. And cadium battery charging for a long time, if the battery of liquid crystal, stop, and you will be filled with electricity cannot completely discharge the malignant consequence of li-ion battery life. EChuan: li-ion battery charging only 300-500 times, then the need for replacement.
The correct view of life and rechargeable lithium electricity: complete cycle times, and charging times have no direct relation.
A battery charging cycles of electricity used by all full, again by filling the air filled. This is not the same as filling. You can do many charging to complete this cycle. Example: you in use, first with the 40%, after a period of time and the 20%, after filling in a 30%, again next 20%. At the midway, namely just 20% of the power of the supplementary 10%, 20% + 30% due to 40% + + 10% = 100%, total cumulative completed a battery charging cycles (this is your period, four times after completion of the battery is next).
Be like again, a piece of li-ion battery only half on the first day, then it with electricity. If so, the half is still in charge and twice, it can only be considered as a charging cycles, rather than two. Therefore, usually may be completed by several charging a cycle. Each completed a rechargeable battery, will reduce cycle. However, decreased is very small, high quality of battery charging, after several cycles will still retain the original power supply 80%, a lot of li-ion battery products after two or three years, is still as usual. Of course li-ion battery life to eventually need to change. Li-ion battery life is commonly 300-500 recharge cycles. If a completely discharge the battery for Q, provided such as not consider each charge of electricity, after the cycle of life in the lithium electricity is total can provide for its complement or 300Q – 500Q power (also quite and you have 300-500 full battery power, and your frequency of the battery has added). If want to use to say your battery, for example, can only understand this: every time you use 1/2 is filling, can fill 600-1000 times, If each would filling with 1/3, can fill 900-1500. By analogy, if the random charging, frequency. Anyhow, no matter how filling, total added into the power 300Q 500Q – it is a constant. Therefore, we can also understand so: lithium battery life and battery charging power, the total number of charging and independent. Deep put deep and shallow light filling for lithium electricity let’s life. In fact, shallow light filling lithium electricity to put more beneficial, only in the power supply module products for lithium electricity do when it has deep calibration of necessary put deep. Therefore, the use of lithium electricity supply products don’t get bogged down in the process, with convenient at first, all charge, need not worry about impact longevity. So, we use USB always do not only for battery charging shallow, harmless, advantageous instead.
In lithium batteries, we may is unfavorable ignored:
If the above provisions, the operating temperature is above 35 ° C using lithium electricity in the environment, battery power will continue to reduce battery power, long time not as usual. If the temperature in this, as in battery charging equipment, the greater the damage will be. Even in a thermal environment, storage battery will inevitably cause corresponding to the quality of the battery. Therefore, to maintain the benefit of the operating temperature is to extend the life of lithium electricity. If in the low temperature environment, namely below 4 ° C using lithium electricity, will also found time to reduce the use of cell phones, some of the original lithium electricity in low temperature environment and even the filling. But don’t worry too much, this is just a temporary situation, different from the use of high temperature environment temperature rises, once the molecules, cells, and immediately heated to previous power. Want to play the maximum efficiency of lithium ion battery, will need often use it, let the electrons within the lithium electricity is always in the flow condition. If you don’t often use li-ion battery, please remember that every month to complete a rechargeable lithium electricity power, do a cycle of calibration, namely the deep put deep filling.
Firstly introduce a few simple formula, the basic electricity hope to make no electronic background readers to a few physical phenomena.
Voltage (V) = current (I) x resistance (R),
Charge (Q) = current (I) x time (T),
Power (P = V x I =
Energy (W) = P * T = Q x V
Any object has impedance, plus a potential difference in both impedance will produce charge through the impedance, the impedance is unit of time (a) through the charge quantity smaller, impedance is unit of time through the charge quantity. If the potentials are unit time increases the flow volume of charge will be reduced, while magnetic unit time through the charge quantity is less. The potential difference voltage (V), called for volts (V) unit, unit of time through the charge quantity amount called current (I), unit for (A), impedance ampere resistance (R), called in ohms (.). The current (I) that flows through the unit of time, the number of charges in the flow resistance in T seconds altogether has the number of charges by T, I used to describe how the charge quantity of nouns for charge (Q), commonly known as the power, the unit is called the coulomb (Q). Resistance of power consumption (P) as I * V, unit for watt (W), representing the power the power consumption. , the energy consumption (W) for P * T, unit for the joule (J), the longer the time the same energy consumption, and the energy consumption of power consumption is bigger also.
Example: a tree in the dry batteries 1.5 V, consumption of 0.5 bulb, power consumption for triple-a current for 4.5 W, 10 seconds altogether through the coulomb’s charge, 30 45 joule energy consumption. Nickel cadmium battery material classification of battery has a lot of kinds, in chemical battery charging in just throw a battery, the battery can be called again use rechargeable batteries repeatedly called secondary battery, the battery is nickel cadmium and alkaline battery in the secondary batteries belong to one. Nickel cadmium battery anode materials are used in QingYangHuaNie oxygen, cathode using cadmium compounds active substances, electrolyte is the use of potassium hydroxide alkaline solution, etc. As for nickel cadmium battery, will be produced in the above, in QingYangHuaNie anode and cathode metal cadmium, thus it has formed in at the potentials. Will nickel cadmium battery anode and cathode ends when discharge, Yin external load extreme charged by external load flow of electrons, therefore to provide energy for anode external load consumption.
Second, excessive charging
In the process of charging the battery voltage increases with the increased power storage battery storage rise gradually, when the electrode material of saturation power battery, if cannot continue to charge, electrolyte, and will produce in the electrolysis anode and cathode generate hydrogen in oxygen, so will the internal cause in sealed battery, will rise to internal pressure inside the cell damage structure. Like this kind of phenomenon called excessive charging.
In order to avoid excessive rechargeable batteries, usually by the damage of the cathode production capacity will be better than the anode, large capacity, such as excessive charge anode can produce oxygen saturation and first, and the cathode is not saturated and won’t produce hydrogen and oxygen to produce spread to the anode and cathode after charging produced metal cadmium absorbed oxygen react, and the reaction rate and metal cadmium speed balance, so can effectively avoid the battery pressure. But if the charging current (use) will be quick charge the battery loses his balance, the pressure inside the battery will open valve, hydrogen and oxygen to battery leakage will reduce external pressure relief valve closed until just sealed battery again. But the gas leakage has made chemical material, reducing internal cause of battery life.
1 how, for the new battery
In the use of lithium battery should be paid attention to in the battery is, after a period of time, while in a suspended state, use the time less than normal capacity to be shortened. But the lithium battery easily activation, long after the 3-5 times of normal
Electricity cycle can activate cells, restore normal capacity. Due to the characteristics of lithium battery itself, it almost no memory effects. So the user’s new lithium battery in the activation process, do not need special methods and equipments. Not only in theory, from my own practice, from start charging method using standard “natural” means the activation is the best.
For lithium battery “activate”, many are charging time: more than 12 hours must be repeated, three times, in order to activate cells. The “three times before the battery should fill over 12 hours,” from nickel battery (such as nickel cadmium and continued nimh). So this statement, say to misinformation. Lithium battery and cadium battery charging and discharging characteristics of very big difference, but also can be very clear tell everyone that I have had all the serious technical data are emphasized the formal overcharge and discharge of lithium battery, especially will liquid lithium ion battery caused great damage. So the best according to standard time and battery charging standard method, especially not for more than 12 hours long battery. Usually, the charging method introduced in instruction is suitable for the battery, the method of charging standards.
In addition, the lithium battery chargers in batteries will automatically stop after filling, does not exist nickel electricity charger so-called lasts 10 hours of Juan “flow” charge. That is to say, if you of lithium battery charger, put in the BaiChong also. But none of us can ensure the battery charging and discharging characteristics of protection circuit will change and the quality of your battery, so no danger in the long term. This is also our long charge against another reason.
In addition, another aspect is the lithium battery also not suited to discharge, discharge of lithium battery also very disadvantageous. This leads to the following questions.
2, the normal use should start charging
In our forum, often can see this statement, because the charge is limited, so it should be possible to batteries run for recharging. But I find a lithium-ion battery charge on the experiment, the data about the life cycle listed as follows:
Circulation service life (10) : > 1000 times DOD
Circulation service life (100% DOD) : > 200 times
DOD is one of the abbreviations depth discharge. From the table, rechargeable frequency and discharge depth, 10% of life cycle DOD than 100% DOD to many. Of course if converted into actual total capacity of charging 10% : 100,100 % * * 1000 = 200 = 200, the latter’s full charge will be better, but in front of the users to do some correction: under normal circumstances, you should have a reservation battery remaining power according to the principle of a filling, but if you charge the battery in the first 2 days you expected throughout the day may not insist, should promptly started charging, of course, if you would carry charger into office again when when.
But you need to recharge to cope with upcoming will lead to the important events of communication is busy, even though there are many more in battery power, then you just ahead, because you didn’t charge real loss “1″ time is life, charging cycles “0 x”, and often times the x will be small.
Battery remaining power after using the principle of filling and not again to you to go to extremes. And as a widespread charging, namely “as the battery power as the best use automatic shutdown. This practice is the practice of cadium battery, the aim is to avoid memory effects occur, unfortunately it in lithium batteries in the present. Once someone because like machine battery power is too low, the warning still not charging continue to use has been used in the automatic shutdown. The results of the example in the later as machine without charging and boot in response to customer maintenance, send. This is because of excessive discharge batteries due to low voltage, that do not have the normal charge and boot conditions.

If you wish to extend battery charger, except the effective use of time to ensure the quality of the battery, the right skills necessary:
1 battery factory, has carried on the activation treatment, and the beforehand, so all spare battery charging electric batteries, a friend said, according to the setting time still charging shortage, assumptions on standby for the names of batteries battery indeed, this kind of circumstance should extend adaptation for 3-5 times more full charge.
2 if a new cell phone battery is lithium ion, before 3-5 times charging commonly called adaptation, filling, in order to ensure that the above 14 hours fully activate lithium ion activity. Lithium ion battery, but there is no memory effects of laziness, should give full activated, to ensure the best after use.
3 some automation intelligent quick charger when instructions lights change, only that filled with 90%. Charger automatically change with slow rechargeable batteries. The best will batteries, otherwise will shorten the time of use.
4 rechargeable lithium batteries, not need special discharge, improper discharge will be damaged cells. When the battery to slow to a ho-hum, reduce fast filling way, Time does not exceed 24 hours. Battery after three to five times after full charge of its internal chemicals will be all “activate” to achieve the best effect.
5. Please use the original or well-regarded brand of lithium battery charger, lithium battery charger should use special, and follow instructions, otherwise it will damage to the battery, or even dangerous.
6 there are many users often in charge the phone open, actually such will easily hurt in the mobile phone service, because the process of charging circuit, mobile phone, if there will be hot exotic phone, may produce instant backflow of mobile phone of current internal damage components.
7. The battery life depends on the number of charge, and shall be avoided when the battery charging more electricity can shorten the battery life. More than 7 days phone battery should be completely discharge, sufficient electricity before use.
There are
battery, self-discharge nimh batteries by day when the residual capacity will be about 1%, lithium batteries will discharge day by 0.2% – 0.3% discharge. In the battery, try to use the special socket, will not be Shared with the home appliance such as TV charger socket.
9. Although mobile network covering area in charge, but in mobile phone, cannot have accepted and call. At this time, can use the mobile phone through transfer function, will be transferred to the side of the fixed telephone calls, in order to prevent the loss, this kind of method for mobile phone is not network covering area or weak signal and temporarily unable to connect also apply.
10. Don’t be exposed to high temperature or cold days, like mobile phones, should not be put in the car, the sun exposure, Or to put their air conditioning, straight blow. When charging, battery has a hot is normal, but cannot make it what temperature “suffer”.
NiCd (11) nickel cadmium battery) before must ensure the battery totally without electricity, battery recharging after must ensure that sufficient electricity.
12 if mobile phone battery for too long, had better not use mobile phone service department to make an application for batteries, also can live with a constant dc voltage, adjusting voltage, current for 5-5 ~ 600mA 6V reverse connect battery.
When the battery is not as long as possible, for no protection circuit batteries charging should cease after the battery, otherwise will affect performance by fever or overheating.
14 lithium ion battery must choose special charger, otherwise it may reach saturation, affect its performance. After charging, should avoid to put in more than 12 hours on the charger, long-term need not when should make battery and mobile phones
