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.
On National Day, first released on the eve of the charge of wealth in 2009 champions and mainland runner-up, the most surprising is the founder of the title is byd, 43, he WangChuanFu with 350 billion yuan worth of ranked first. WangChuanFu from broker peasant boys to billionaire group company CEO, from 26 to national senior engineer, associate professor of global “batteries etc in automotive field,” then what is the richest be done business, wizards? WangChuanFu think: the most important thing is to have a good taste.
On February 15, 1966, WangChuanFu in anhui WuWeiXian an ordinary farmyard is born. After graduation from the university WangChuanFu graduates entering Beijing institute of nonferrous metal, then the 26-year-old WangChuanFu was promoted to be the abnormality, deputy director of the institute of nonferrous room 301, became the youngest place class staff. In 1993, non-ferrous institute was founded in shenzhen more battery Co., LTD, WangChuanFu was appointed general manager of this company. His political career is bright.
But that was WangChuanFu takes 2 million yuan to buy 3 – a giant “, and to the buyer. Wang realized the development of mobile phone of rechargeable batteries will demand grows. Discerning the original WangChuanFu enchanted where, made a bold decisions — from more battery Co., LTD, create. The average person is stupid, is too risky.
In 1995, shenzhen cold February WangChuanFu, to make the investment management LvXiangYang cousin borrowed money, 2.5 million registered and established the byd technology Co., LTD. Took more than 20 people the lotus pond in shenzhen in the workshop of the old setting sail. How to open? At that time, the Japanese rechargeable batteries, domestic manufacturers skillfulness bought many core assemble, less profit, up almost no competition. After careful consideration, WangChuanFu decision depends on its technical research, from the beginning, the highest levels of vision technology profits of the most lucrative rechargeable battery core components – core production. Facts have proved that WangChuanFu it can move is a deadly nociceptor, key.
Seek the way of rapid development WangChuanFu in an international battery industry trends, Japan found in native announced will no longer ni-cd battery, which will cause nickel cadmium battery production base of international big shift, WangChuanFu immediately realized this will create an unprecedented for China’s battery enterprises of a golden opportunity, decided to immediately involved in nickel cadmium battery production. In 1996, byd companies replace sanyo become Taiwan cordless phone manufacturers large battery suppliers. In 1997, they nickel cadmium battery sales rose to world ranking fourth place. At present, nearly 15% of the byd global market share become China’s largest mobile phone battery production enterprise. In nickel cadmium battery domain, the byd ranking first and second nimh batteries, ranked third lithium batteries. WangChuanFu became king “Chinese” battery.
A company is not difficult, difficult is a product production, difficult is how to be as little as possible of the evolution of large output, in the shortest amount of time and maximum progress, the largest profit, which requires vision. Many business failure is not a lack of funds, and lack of vision. WangChuanFu have the biggest capital, is the strategic vision.
In the market WangChuanFu in battery, like that of state-owned company general manager from the position of the sea, like crazy WangChuanFu and made a bold decisions, decided to enter the auto industry. WangChuanFu dream is to be a new energy vehicles leader. The idea is WangChuanFu, through the battery production areas of core technology advantage, build China and even the world no.1 brand electric cars. He said: “the future is the hybrid and electric vehicles, rather than gasoline vehicles.” Almost all people think that it is a “heat”. Because it was a corporation of China automobile industry into the tide, cobolli gigli LiShuFu etc are involved in this one, and WangChuanFu never visited automotive field, became the most underrated “catch” of tide.
WangChuanFu in 2002, a “fake” buying Chinese car companies, then change to the company the first “plug type plug (in) hybrid” production enterprise. In January 2004, shenzhen has 200 byd make lithium ion pure electric car rental operation, became the national investment vehicle demonstration, the first true exhaust zero emissions. Byd to launch the “proceedings F3DM” dual mode vehicle than GM (GM), which will also around two years earlier models. The fourth quarter of the year will launch a 100% “, and “E6 electric announced next comprehensive into the USA market. “Time” car battery can E6 driving 400 kilometers, technology leading Toyota, nissan than one to two years. Therefore, WangChuanFu also won the “king” of electric nickname. WangChuanFu real Chinese had great expectations for the words: “byd autos sold in 2015 become China’s first by 2025, became the world first.”
In 2008, hu run 100 rich list, WangChuanFu to 60 billion yuan in the first row is targeted at 22, this year, and soared to the first of buffett’s shares are closely linked. Buffett in 2008 September 18 million hk dollar buy-out byd 10% stake. Buffett’s investment attract the smell of new energy vehicles is byd. Buffett said more than once, he took the byd new energy vehicles, especially the vehicle development prospects. He says, can also have two different fields and car battery technology and make them very well together in the enterprise, it is very rare, everyone global energy crisis and let people and future prospect of electric vehicle. In 2009, warren buffett, buffett says shareholders WangChuanFu is “true star”. Therefore, the byd’s share price rose six times. So, WangChuanFu “accidental” and “miracle” to become the new song.
Hurun report said: “in the global automotive industry under the environment of decline in 2009, and China’s new in the automobile industry, the unexpected, also in surprise. WangChuanFu because with the science and technology, new energy and environmental protection and innovation of the trend, leading to a new pattern of the world automobile industry.”
Eye is the direction and speed, eye gaze is potential, is in the future. Bill Gates is the richest man in the world, as many people in exploring the mystery of his wealth. He summed up the land said: “my eyes.” WangChuanFu because eye, so only after 14 years, from ordinary became China’s richest gens going to work.
The businessman hu xueyan, have such a words: if you have a county, then you can make a county business, If you have a province, then you can make a province business, If you have the vision, so you can do the business. Vision is not wealth, but also represent the honor and the value of life, life brilliance and direction.
For mobile phone battery principle of work, perhaps many friends want to know, only by understanding the handset battery principle of work, everybody can understand oneself one step further, to avoid the mobile phone battery explosion of the phenomenon.
The classification of battery
Nickel cadmium battery: consists of two side is composed, plate making, nickel metal is the other side of the metal cadmium, so called nickel cadmium battery this two kinds of metal in the battery in reversible response, so battery recharging, this also is the first generation of mobile phone battery, use rise need maintenance.
Nickel cadmium battery: nickel cadmium battery has another name battery, because it does not contain cadmium metal, not pollute the environment. It’s power reserve ratio nickel cadmium battery more than 30% to 50%, mobile phone calls and prolong the time and so on, but the 30% with nickel cadmium battery, but differ in internal materials
Nickel cadmium battery: is a kind of high energy density of the battery, and the same size of the nickel cadmium battery, compared to nickel cadmium battery power reserves bigger and more light weight. Based on the safety of nickel cadmium in batteries, it also has a built-in control chip, to provide power, voltage, current, many aspects of protection, can avoid to control charging battery constitute the excessive caused dangerous phenomenon, and further improve the safety of using battery.
Because the two kinds of battery has not put into use, we will not only introduces the principle, for everyone in the use of nickel cadmium battery principle are introduced.
Nickel cadmium in batteries for lithium ofits, lithium is a kind of metal elements, is a silvery white, soft and chemical properties are very lively in the metal, metal is the lightest. Nickel cadmium battery anode materials are usually the active compounds, lithium anode is special molecular structure of carbon. Common battery anode materials for the main component LiCoO2, charging the battery, and the potential of the positive force between compounds, lithium ion release molecules across embedded in the structure of carbon. Discharge, lithium ion from slice layer structure of carbon compounds, and positive, because of lithium ion movement and thus output current for mobile phone use.
Nickel cadmium battery protective circuit circuit
Nickel cadmium battery recognized use efficiency and security, and makes it even higher prices, sales still grow rapidly. And nickel cadmium battery protective circuit circuit is the patron saint of nickel cadmium battery, can effective let nickel cadmium battery for work on the protection and control, and the so-called nickel cadmium battery protective circuit circuit is the nickel cadmium battery is the protection circuit.
1 and the necessity of protection circuit:
Li-ion rechargeable battery charging or if there is often happen.according to discharge battery inflation, leakage protection circuit abnormal phenomenon, can prevent itself or malfunction with the charger, or because of improper use, battery failure and the performance deterioration and Settings. In normal conditions, the protection circuit is not working.
2, the protection circuit circuit of the installation position:
Protection circuit with a single battery and panel is a machine itself, even if the charger or fault, protect circuit can prevent cell damage, discharge, characteristics of degradation. These protect circuit must be put in the panels, and the professional company according to different battery design circuits.
3 and avoid protection circuit damage:
Avoid the use of static in places such as batteries, laboratory, precision instruments, empty place near the thunderstorm, etc.
4 and the battery safe charge temperature range:
The battery is best in between 45 degrees centigrade 0 – to maintain optimum charging, the safety of charging protection circuit, otherwise easy damage and reduce battery performance life. For the strong sunlight parked in the car, the battery is not suitable for placement.
Nickel cadmium battery is composed of two plates, one is using nickel, another is the cadmium in batteries two metal occurs reversible reaction, battery recharging. Nickel cadmium is characteristic of “firm”, cheap price. Defect is for environmental pollution metal cadmium battery capacity, small, short life, so the battery is nickel cadmium battery, cheap, and every memory effects are charging and discharging charge shall be first.The battery is nickel cadmium battery replacement products, relative to the nickel cadmium battery, it is all the more remarkable nimh batteries. It greatly reduces the nickel cadmium in batteries “memory effects”, which makes use of nimh batteries more convenience, more long use life cycle (up to 1,000 times). In addition, still have the capacity nimh batteries, discharge, high resistance to overcharge depth and discharge, charging time short obvious advantages. The most important is no longer used nimh batteries toxic metal material, can eliminate the as pollution to the environment. At the same time, in the electrical characteristics and nickel cadmium battery basic similar, in actual applications can completely replace the nickel cadmium battery without the need for any modification of the camera? / P >
Of course, also not perfect nimh batteries, it also exist some disadvantages. It is poorer, high temperature characteristics in 45 degrees Celsius above and below 0 degrees under the environment of the cryogenic environment, will not work properly nimh batteries, even cannot start the camera, In addition, the battery is relatively high self-discharge, storage after period of time will find it’s power decrease, There is a nimh batteries exist mild memory effects.
On August 9, 2007, in shenzhen, the byd mountain long, base area of newly 180 million square meters, has made more than 30 mountain, flattened out more than 120 fishpond, dug up 7.5 million soil base with plants and 56 seat manufacturer, tens of thousands of workers in production line is busy byd second car F6 also walk from here under the assembly line, formal… At this, all WangChuanFu palm byd, unavoidable pride went on passenger cars field byd rumoured to China’s first by 2015, the first by 2025 do. So pretty, shock followed.
The base in mountain, 29, twelve years ago WangChuanFu just quit the job, and the state-owned stable business partners in shenzhen dozen the lotus pond in a shabby workshop. Knock The shabby workshop is almost all their activities during the day, make development, night on the floor. This is WangChuanFu business started. For resignation, WangChuanFu said it wasn’t hesitate, the firm can do it myself. When he LvXiangYang borrow money from my cousin, LvXiangYang business, “you are hard to understand why, national cadre adventure sea?” WangChuanFu obdurate, “I was to study the battery, I believe I can do well, believe the potential battery industry.”
In the mid 1990s, cell phone, WangChuanFu popular in mobile phone battery zeroed in on a large emerging markets. Just at this moment, Japan announced in Japan ni-cd battery, WangChuanFu think this is an “a” opportunities, decide ni-cd batteries. In spite of difficulties, but WangChuanFu still firmly into the nickel cadmium battery production, and the end of 1995 were obtained in Taiwan’s biggest cordless phone manufacturers large orders.
In 1998, the Asian financial storm, global prices tumbled, the byd batteries are low cost advantage fully, philips, panasonic, etc are turning byd purchasing batteries. Only three years, the byd will become a battery industry leader.
Then, the byd interventional techniques of high difficulty nimh batteries and lithium battery production. The two fields of Japanese companies are also established a world, only three years of small companies want to challenge the giant, sanyo et inevitably people jokes, but WangChuanFu or do, and succeeded. Now, the byd nickel batteries, mobile phone using lithium batteries in global market share has to be ranked first, byd two cell phone battery manufacturer
