The battery series and parallel up use, this sounds like very simple, however, follow some simple rules, can avoid unnecessary problems.
The cells of the battery are needed to connect, the working voltage. If you need a higher capacity and more current, it should be parallel. Batteries, Other cells, the series and parallel to combine these two kinds of methods. A laptop battery may be the fourth quarter 3.6 V lithium ion battery connection, total voltage reached 14.4 V, And then, the two groups together, so the battery in parallel, the total power of the battery can be from 2000 to 4000 ma ma when. This method is called “four strings up two and”, it means: the two groups of four batteries battery series in parallel.
The watch, backup storage and cellular phone in general use a battery. A quarter of the nominal voltage nickel-based battery is 1.2 V, alkaline battery is 1.5 V, silver oxide battery is 1.6 V, lead acid battery is 2V, li-ion battery is 3V, and lithium ion battery of nominal voltage is 3.6 V. Using lithium-ion polymer and other types of lithium battery, its rated voltage is generally 3.7 V. If you want to get this uncommon as 11.1 V of voltage, would get three series of the battery. Along with the development of modern microelectronics technology, we have to use a 3.6 V of lithium ion battery, cellular phone and low consumption of portable communication products. In the 1960s, illuminance meter in widely used in battery, mercury from the consideration of environmental protection, now fully to withdraw from the market.
The nominal voltage nickel-based battery for 1.2 V or 1.25 V. Between them, in addition to the market preferences, doesn’t make any difference. Most of the commercial battery, the battery voltage for each section 1.2 V, Industrial battery, the battery, the battery and military aviation each battery voltage is still 1.25 V.
tandem
The portable power to high, usually by two or more batteries battery power of the connection. If the use of high voltage battery, conductor and the size of the switch can be done very small. Moderate price industrial power tools generally use voltage for 12V to amounts of V battery power, And advanced electric tools used for 36V of voltage 24V to battery to gain greater power. Automobile industry ultimately starter ignition battery voltage from 12V (actually is 14V) to 42V 36V, even. These cells are up by 18 series lead acid battery. In the early hybrid cars, used to supply voltage, 148V battery. Compare the new models used batteries, 450V voltage up to 500V, most of the battery is nickel base. A voltage 480V for the battery is nickel metal hydrogen by 400 section nickel metal hydrogen battery series. Some hybrid cars also in lead acid battery had done a test.
42 V battery expensive cars with, and compared with the 12V batteries, it will produce more arc switch. Using high voltage battery brings another problem is the batteries are likely to encounter a battery failure. It is like a chain of battery, together, appear this kind of circumstance of higher risk. If a battery has a problem, it will reduce the voltage. Finally, a section of the battery “disconnect” could interrupt current. And to replace “bad” battery is no easy task, for new and old battery is mutually match. Generally speaking, the new battery capacity than the old battery is much higher.
We look at an example in the third quarter of the battery, the battery only 0.6 V voltage, rather than the normal 1.2 V (figure 1). With the working voltage drop, it is faster than normal cells to discharge the critical point, at the same time, the end of its use time also has shortened. Once a device for low voltage power off and the rest in quarters, still can put the battery power to send out of the store. Then, in the third quarter of batteries are still, if still contain internal, then, will load the battery voltage output chain will drop dramatically. In one group, a quarter of serial battery of battery, like a blocking pipe plug, will produce the huge resistance, prevent current flow in the past. The third section battery will short-circuit, this will make the terminal voltage drops to 3.6 V, or that link disconnect the battery and cut off the electricity. A battery performance depends on the stack the worst performance of the battery.
parallel
In order to get more power, can put two or more a battery parallel. Besides the batteries in parallel, another option is to use the size bigger batteries. Due to the limit of the battery can be chosen, this method does not apply to all cases. In addition, large size batteries are not suitable for battery needs to make the appearance of specifications. Most of the chemical battery can be used in parallel, the most suitable for lithium ion batteries used in parallel. By four batteries in parallel to keep the battery voltage, current, and 1.2 V and running time is up to four times.
Compared with the battery, the battery in parallel in the series circuit, the high impedance or “open”, but the batteries battery, will reduce load capacity in parallel, and shorten the time of operation. This is just like an engine just launched three cylinders. The damage caused by a short circuit will be bigger, because, this is, in short, when malfunction of the battery will rapidly deplete power, the other battery and fire
parallel
Using this method, the series is flexible in design, can use the standard cell size needed to achieve the rated voltage and current (figure 3). Should notice: the total power of the battery will because of different connection method and change. Power equal voltage by current.
Battery consumption and people’s life. People enjoy living in battery, bring convenience to waste batteries and guide the enormous problems of environmental pollution. Only a quarter no.5 batteries can make 1 square meters of permanent loss of soil utilization value. Because our country alkaline battery recovery system is not perfect, plus the people environmental protection consciousness to be raised by waste old battery brings the environment pollution nots allow to ignore.
But “cell regeneration treasure” perhaps can completely change the situation.
The cell regeneration treasure “and domestic markets generally battery charger product differs is, it adopts the principle is to use its internal a special kind of crystal, make the chemicals inside the cell activation and reactivated, rather than charging.
“Battery” use of renewable method is simple and easy to use. Ordinary alkaline battery simply add “cell regeneration treasure”, after the initial shock of renewable energy and even can reach the battery, repeated use of energy by 120% after 30 times, still can achieve energy for more than 80% of energy. Above all, “battery” using renewable intelligent microcomputer control and adaptive battery technology, can accurately identify any fully in the different combination of different kinds of cells, accurate judgement of the situation, won’t cause the battery, the battery overcharge have to ensure safety and thermal protection, overcharge protection, short circuit protection etc. Various protection measures, the user can be at ease completely.
After measuring, 4 ordinary alkaline batteries in “battery” regeneration in 10 minutes later, the digital camera can reach more than 30 consecutive camera. If you want to complete the regeneration, only activate more than an hour. “Battery” to activate regeneration by this section 4 of electricity consumption dry less than one penny, because “cell regeneration treasure” work for the power 6W, 6W x 4 activation time 1.3 hours x 1 yuan/degrees = 0.0078 yuan.
According to relevant personage introduction, the China consumes more than $60 billion batteries, produce more than 200 tons of garbage batteries, such a huge amount of waste batteries handled badly, will cause to the environment destruction of inestimable role. “Cell regeneration treasure” inputs, if the product can postpartum use, is expected to reduce waste electrical pool, according to 500 million yuan, each 2.5 billion yuan will save 1250, can effectively reduce environmental pollution problems. It requires people to improve the environmental protection consciousness, in the life consciously with good old battery. Dry
Expert analysis, cell regeneration treasure is a new concept of product, whether from the economic benefits and environmental benefits or in the future will have wide prospect.
Battery has reliable power supply voltage stability, convenient to move, etc, it is widely used in power plant, substation and communication system, electric car, aerospace and other departments. Batteries are mainly ordinary alkaline battery, nickel cadmium battery and valve vrla battery. Common battery due to use short life, the efficiency is low, the maintenance, environmental pollution problems, such as acid mist its usage scope is limited, currently has gradually be valve vrla battery. Valve vrla battery using seal structure, not the whole existence of ordinary lead-acid battery electrolyte leakage air, such phenomena, the use of safe and reliable, long life, during normal operation of electrolyte, testing and tuning acid water, also called battery. It has been widely applied to the post and telecommunications, shipping transportation, emergency lighting and many other fields. Alkaline battery is nickel cadmium characteristics of small size, high magnification discharge operation simple maintenance and long service life, but because it is low and leakage monomer, cost is high and easy to environmental pollution, thus its limited use, mainly used in electric tools and various portable electronic devices.
Common battery consists mainly of plate, electrolyte and battery tank components. Positive and negative plate are made by board and active substances, including one on the plate is active substance is brown PbO2 (PbO2), negative plate on the active substances for dark grey sponge pure lead (Pb). Electrolyte is with distilled water (H2O) and pure acid (H2SO4) according to certain proportion. In the process of charging, electrolyte and positive and negative plate on the active material produces chemical reaction, thus become the power stored energy, In the process of discharging, electrolyte and positive and negative plate on the active material produces chemical reaction, the storage battery energy conversion in inside into electricity supply load. In order to make the chemical reactions can be carried out as normal and electrolyte must have certain concentration. Battery tank is plate and electrolyte containers, it must have good acidproof performance, insulating performance and high mechanical strength.
In the batteries positive and negative plate load between access, began the process of discharge battery. At this time, are plate, plate potential negative potential, minus the active substances (on the plate PbO2 and Pb) are constantly to lead sulfate PbSO4 (sulfuric acid), electrolyte gradually into water, electrolyte proportion, thereby decreased gradually reduce battery resistance increases, the electromotive force. If the battery of positive and negative plate between output voltage battery voltage access than high dc power, storage battery charging process began. This is a potential for plate, plate and rising, negative potential for negative and positive gathered on the plate PbSO4 gradually become PbO2 PbSO4 on the plate, gradually becoming spongy Pb. At the same time, electrolyte H2SO4 synthesis of increase gradually, gradually reduce water molecules, and gradually increase the proportion of electrolyte, battery voltage and continuous improvement.
2 fast charging battery technology
The method using the conventional battery charging ways, small current slow to a new battery charging 70h need more early, should also 10h above average charge. Charging for too long a time, not only can spin charging monitoring time, causing the waste energy, also limit the battery recycling, and increase the number of maintenance. In addition, for such as electric car battery power requirements for the occasion, use rise very convenient. With rapid charging method, can shorten the time and improve the rechargeable battery charging efficiency, energy saving, and better meet the needs of industrial application, has the significant practical significance.
It is very long history of batteries, the world’s oldest about 2,000 years ago, battery originated in Baghdad, this is called “the battery, still preserved,” in the Iraqi capital museum (now? Have you ever been blown)? .
Batteries are two commonly used respectively, the parameters of voltage and capacity. Voltage across mainly depends on the material. Generally, the dry are 1.5 V, and rechargeable batteries voltage 1.2 V. How much is the capacity for electricity, with discharge current and discharge time of product. For example 500mAh capacity of the battery, the battery is refers to the discharge current 500mA, can use 1 hour. Obviously, if 250mA with the discharge current, can use 2 hours, and so forth.
The battery is used commonly, alkaline batteries, manganese dry nickel cadmium battery, the battery, the battery laminated button. Manganese zinc dry, nominal voltage 1.5 V, cheap, but continuous discharge, not suitable, and cannot anti-shocking charge, only applies to a small current electronic circuit. Manganese dry a strange characteristics, intermittent discharge time and continuous discharge than time, this is a common trick of dry.
Alkaline batteries, nominal voltage is 1.5 V, its electrolyte is water soluble potassium hydroxide solution, large capacity, can anti-shocking, various aspects are superior properties of manganese dry. In practice, the need to large current circuit, alkaline battery can play a role. Alkaline dry in the use of the tape, heard WALKMAN than common battery life long, the camera in many flash every cell, can use nickel alkaline battery is the best choice. But the alkaline battery price is more expensive.
Most of the alkaline battery chassis, marked “no charge” Chinese or English, but in fact, the alkaline batteries can be recharged, can charge a dozen times. Only on the alkaline battery can take small current charge, using the method of charging current 50mA advisable, and most of the charger charging electric current is larger, the battery in liquid flows, corrosion appliances. LR20 LR6 battery, representing one representative 5 alkaline.
Ordinary manganese, single to dry for the model, the common R v battery R6P is high capacity. Bitbaby like elephants “brand alkaline battery electric equipment.
Many calculators are used in the solar energy, light photocell to button batteries. Solar cells have rectangular flake, also have the round shape transistors. Each piece can produce 0.5 V, more pieces of voltage series, in order to improve the voltage of parallel to increase output current. But generally and button cells in parallel, in the power stored at any time, to small load power supply.
Nickel for every battery is well known, no longer. According to Bitbaby know, small Japan in early 1990s was banned in every cell, nickel production to protect their environment. Now on the market IN love and never dull so much beauty of the battery is nickel isolation which come from? Now, with the help of nimh batteries, and no capacity and environmental protection, and memory effects. Cadmium harmful to human body!
Alkaline batteries battery power of carbon sex is 4-5 times the price of carbon, 1.5-2 times. Carbon sex cells for the electric current in low, such as arts, remote control, radios, Alkaline batteries for the electric current in high, such as BP machine, CD, PDA, etc.
The earliest practical battery into the market is xinmeng dry. In 1860, kronor (French) is the Leclanche medias invented the prototype battery acid manganese zinc, the battery is also called Leclanche batteries. It is a negative zinc, battery center is as the anode rod, the graphite conductive materials for graphite anode zone around the bar and carbon powder, powder manganese dioxide anode zone of NH4Cl and to paste ZnCl2 mixture.
Alkaline battery xinmeng in 1950s after entering the market. In recent years, the market in our country, acidic xinmeng batteries are expensive alkaline battery instead of zinc. Alkaline xinmeng battery electrolytes KOH is.
The structure and alkaline battery acid battery completely opposite, battery anode, zinc center is a powder, positive area, is in the outer shell MnO2 and KOH mixture, cylinder is. Alkaline acid manganese zinc overcomes the battery storage battery voltage instability and faults, but still be non-rechargeable batteries.
Both have the same voltage is 1.5 V, but also volume of alkaline battery capacity is bigger, more can adapt high discharge current.
Alkaline batteries, nominal voltage is 1.5 V, its electrolyte is water soluble potassium hydroxide solution, large capacity, can anti-shocking, various aspects are superior properties of manganese dry.
