digital batteries

In recent years, electric vehicles extraordinarily rapid development momentum, and many people like the green of this convenient means of transport, use of electric vehicles, according to incomplete statistics, the number of people in the country were put on a million, but 90% of users experiencing the same problems six months after the use of electric cars, cars Pao Bule how we should load – is a sharp decrease in Laptop battery capacity. This is the commitment of the distributor of origin: Our cycle battery life of up to two years, replacing the battery for one year if there are quality issues, the battery is completely different for a half – year began to age, so most consumers are looking for distribution operators to replace the battery.

Dealers spend a lot of energy, time tested the battery and the battery is no big problem, they put the drums a little maintenance, maintenance of back to consumers may be near the battery looks the same problem, cars Pao Bule How much we should charge in order to avoid complaints. In no other choice but dealers will be issues with battery manufacturers, battery manufacturers, but they are unable to explain the difficulties the actual design and the battery charge-discharge cycle tests indicate that the cycle of life is indeed more than three years when the production process in strict compliance with quality control may be why much of the battery will be after six months of aging? Return rates rise sharply? In the end that broke our batteries?

To this end, I visited a number of professional skills of experts in cell research and academics, including Shenzhen map of America was the inventor of the shipper frequency pulse Jiang Haiqing us said: “Batteries not misuse, but poor support.” The IBM 40Y6799 battery is the source of premature aging cheap charger, this charger is simply to accelerate the aging batteries.

I survey also revealed that: At present, many manufacturers of chargers blindness in the pursuit of short-term benefits of price competition “lowest price best” To this end, they are so reduce production costs for shippers to use some electronic components at low prices, and a simple constant current, constant voltage, the charge mode of maintenance of three “low” to meet market demand for the acceptance of so-called consumers to increase product sales and corporate profits, Who would have thought that such low-power chargers, battery low now is the acceleration of the root causes of cellular aging.

Why is this so? First, let’s look at the work of the lead acid battery loading and unloading process: lead acid battery charging and discharging processes of electrochemical reaction is the process of charging, lead sulfate to form lead oxide, discharges of lead oxide is reduced to lead sulfate. Lead sulphate is very easy to crystalline material, when the Dell Inspiron B130 battery electrolytic solution of sulfuric acid concentration of lead is too high or too long a period of inactivity when the static lead sulfate will “take as a group” for form small crystals, which lead sulphate small crystals of lead sulfate and attract around like a snowball that the inertia of the formation of large crystals of sulphate of lead crystal after the small current at low voltage , on the basis of pricing, not only reduces the lead oxide can not be recycled, but will also speed up the deposit attached to the plate electrode ON, which causes a gradual decline of the working area plate electrode (which is also a low power, low current load-lead low-grade battery charger acid to accelerate the root causes of aging), this phenomenon is that people are called sulfate, which is often said aging. Then the battery capacity will decrease gradually until it can not be used. When the lead sulfate will also attract a large number of stacking of lead particles during the formation of conducting sticks, through positive and negative plates of lead sticks between the bridge and cause short-circuit the battery. If the electrode surface or seal molded case has several cracks, crystals of lead sulfate builds up in these cracks and produce tension expanded and eventually burst into the washer or break the shell, causing the hp PP2182D battery can not repair the physical damage.

Second, this low cost charger constant voltage phase of post-gas analysis very serious (that is, a serious loss of water), it directly affects the cycle life of lead acid batteries, This phase of the load current is smaller reaction combination plate is not full access to the runoff phase responsible for the reference method to a sample of high precision is not caused by the battery at an advanced stage of severe dehydration , which can exceed 20% loss of water, charging the latter part of the rapid increase in temperature above 40 degrees above normal, the sharp increase in self-defense, even if the battery is fully charged, the charger can not be filled after the bifurcation load, so that after 180 charge cycles, the battery in the group inevitably arise between the voltage of the single cell capacity and the level of difference 260 cycles, after a decline caused premature battery capacity, aging, damage.

To correct the dehydration and sulfate battery problem, Shenzhen, pulse charger inverter card America was repeated for several years of routine testing that uses non-symmetrical micro-tech digital control, monitoring real-time voltage battery and the current changes, dynamic load frequency adjustment, the use of specific impulse, so continue to organize, activate the sony VGP-BPS5 battery plates so that the plate has always been to maintain a “status” clean, ensuring that each count of the best. America card was also set up internal charger substantially the value of the instantaneous frequency high voltage current pulse can effectively remove the sulphate to clear the circuit, so that regeneration to restore the crystals of lead sulfate in the oxide lead to repair old batteries, semiconductor physical terms, as long as sufficient if the high voltage breakdown of an insulating layer may be, once the insulation was ventilation, lead sulfate of thickness will be rendered conductive state, the strong current under the action of oxidation-reduction re-generate the lead and sulfuric acid, to participate in the electrochemical reaction. If the pulse width short enough support, we can ensure that low-cost power generated in no time under the conditions of the analysis of the breakdown of gas crystals of lead sulfate to do so without compromising battery According to the principle of using the elimination of sulfate impulse to restore the battery capacity, so that the normal battery to extend the cycle life of more than twice the results.

America card was such a pricing method can not only reduce water loss and prevention of cell aging, but also repair old batteries to improve performance of low temperature discharge. Finally, I again appeal to the user being aware of their method of charging fees to save money for themselves, but also for the country to conserve energy to reduce lead acid batteries on the environment caused by pollution to make a contribution.

Increasingly pressing problem of climate change, the ability to Copenhagen for control of the temperature rise in 2 ℃ target relates to the serious problem of human existence. It is generally expected, and Costa will be the focus of the participating countries will focus on specific commitments to reduce emissions, analysts believe it will contribute directly to the new energy industry of the Laptop battery and the development of green lighting.

New Energy Battery Industry: program benefits new energy vehicle development

According to media development and reform of the Commission motor team leader Wang Shulin, has revealed “new energy program for vehicle development was presented to the Council of State should officially promulgated in March 2010. In addition, State agencies will also be launched next year, development of new energy vehicles for the five accompanying measures. Analysts estimate that the new energy industry of the battery will most benefit from the concept of new energy vehicles.

The new energy vehicles in March next year, introduced the planning or

If the concept of energy market news, sauteed, in policy came good constantly. Held recently in Nanchang, the new energy vehicles and lithium-ion batteries feature forums, the National Development and Reform Commission automobile team leader Wang Shu-lin said that China will soon release of new energy vehicles, specifications techniques, and new energy vehicle development presented by Development and Reform Commission of the State Council, was officially promulgated in March next year.

Industry analyst with CITIC Securities automotive Cheng believes that this concept for some companies, the new toshiba PA3191U-2BRS battery energy as Shanshangufen, Jiangsu Guotai other battery manufacturers to make more, but for the entire automotive sector in particular, SAIC, FAW and other great little effect on car companies. Energy vehicles would be the automotive industry and its upstream segment of the cell concept of society have an impact. March release, “the restructuring of the auto industry and the revitalization plan” submitted in 2011 to form a production capacity of 500,000 short-term goal, which is currently more than 1300 million units for the production of the automotive industry is concerned, a very small proportion of new energy vehicles. For their own societies smallest battery to the past, mainly the provision of mobile phones, computers and other battery-quarter production traction batteries, 500,000 will be a huge volume of activity, hence the emergence of new energy concepts will greatly enhance the performance of these companies.

From March 2009 “published by the restructuring of the automotive industry and the revitalization of planning” in response to vehicles with new energy into the electric car, Development and Reform Commission has been clearly put forward in 2011 to form a production capacity of 500,000 short-term goal. It is understood that electric vehicles, power batteries, electric motors, power electronics, the cost of key components, which represents the cost of BATBL50L6 electric vehicles by 30% -50%. Based on the calculation of 500,000 electric vehicles with a value of annual production expected to reach 1,000 billion yuan.

Previously, the two countries issued a joint statement in Beijing, the two sides agreed during the next five years, Sino-US Joint Research Center of the investment for clean energy at least 150 million U.S. dollars the priority research topics will own cars. The market believes that Sino-US Joint Declaration on cooperation in energy sources such as news, digital, relatively rare in history, new energy vehicles are expected to form a positive plate material.

The State Council Development Research Center of Industrial Economics Research Department, Feng Fei energy experts believe that both parties should take the initiative in the field of electric vehicles for cooperation, Chinese electric vehicle is a huge market and cost advantage manufacturing, but the overall level of automotive, industrial technology, the infrastructure was not enough, the United States, it is precisely in this area has a great advantage if both parties take the initiative in the field of electric vehicles to launch a new type of automotive products, will become a reality.

Automotive Li-ion batteries to double next year transfers

As environment-friendly vehicles worldwide are sought, the hybrid electric cars and sells the coming years, the automotive market lithium will develop rapidly. Fuji Institute of Economic Research said that from the 2010 car market lithium batteries will quickly recover and continue to grow. The report predicts that by 2014, manufacturers of batteries that the overall amount of total shipments in 2008 increased by 45.2% to 6.2392 billion yen. Among them, rechargeable apple A1022 battery market will be extended to 4.9983 billion yen, an increase of 66.8%. It should be noted that the needs of the automotive industry will become the main engine of expansion of the battery market is expected in 2009 shipments of lithium batteries automotive sector will amount to ¥ 10,400,000,000 in 2008, based on double ¥ 25000000000; In 2014, the market size will expand rapidly to 2.25 billion yen, or about 215 times in 2008.

Management Consulting International firm Roland Berger Strategy on the global outlook for new energy vehicles in the last research report predicts that by parts of the electric power in 2020, China is the drive assembly and components market worth 10 billion euros Chao, whose 2011, 2014 and 2017 the market value of 600 million euros, respectively, 2.4 billion and 56 billion euros, the estimated market value of the environment in 2020 will reach 6.5 billion euros, even a conservative estimate will reach 2.4 billion euros. According to forecasts the next 10 years, Chinese enterprises in the hybrid and electric vehicles future developments in the field have an advantage, in particular, the basic components, including developments in the field of battery has a great potential because Chinese companies have the advantage of cost of raw materials, manufacturing equipment and labor cost advantage.

According to Roland Berger predicts that 2020 will be the main markets in Western Europe, electric vehicles and plug-in hybrids will be more than 3 million in annual sales, China ranked second to reach 1.58 million of units.

With the plug-in hybrid electric vehicles of all relevant factors, the Roland Berger predicts that by 2020, elements of the VGP-BPL10 battery of the global market share in the largest share of the market size of EUR 9,600,000,000 — 297 between. Now that the Chinese suppliers and Japan, South Korea, North America, Europe, the supplier has a significant cost advantage compared to, the future of the standard battery of quality, durability and differences prices will become increasingly small.

Roland Berger estimates that the demand for battery electric vehicles will be the future of lithium the main source of output growth is expected for 2020, there will be eye-catching 70% of average annual compound rate of growth. Despite the significant growth in demand, but because of higher reserves, experts do not believe that the production of lithium will be a shortage, but there may be a price increase in the risk of a temporary existence.

Promising varieties of independent innovation of automotive batteries

Shenyin analyst Wang said that under optimistic about new energy policies to promote investment opportunities in the automotive battery industry, promising varieties of independent innovation of automotive batteries. Shenyin the next 3-5 years, Ni-MH batteries, HEVs will remain the mainstream of new energy vehicles, HEVs will PH EV, EV co-existence about 10 years. In 3-5 years later, with iron to increase the performance of lithium phosphate to lower costs, and the national network of charging stations in place progressive lithium iron phosphate as the main engine PH of the EV, EV mark the beginning of a broad development prospects. Recommended Keli far Shanshangufen, Jiangsu Guotai, Tibet mining.

Shenyin should grant political future, and the rate of localization is likely to hook. In the development strategy, pending the countries new energy vehicles as an opportunity to catch up from behind their own technology. I believe Sino-US cooperation, China will continue to insist on independent R & D path. Possible future introduction of new energy standards car allowance, spare parts and the main rate of localization will be linked to, and encourage the autonomy of key parts as soon as possible and depending on the location of raw materials. At the same time the state will improve the access threshold, and rigorous review system products.

Shenyin should follow the state ministries and commissions, will be introduced to encourage large-scale electrical vehicles and the development of specific incentive policies. The industrialization of new energy vehicles, including the most important policy for consumers to buy new energy vehicles are subsidized, and the development of new VGP-BPS13A/B energy vehicles and infrastructure planning. The introduction of these two policies that will address bottlenecks in the consumption and use of the bottleneck.

Introduction

Although the extent of the tension has been used in many portable products separately estimate the remaining power of battery, but this way there may go up to 50% margin of error. The Laptop battery voltage and current will be the relationship between discharge rate, temperature and aging of the battery varies. For example, compared to the same power consumption, low flow, high throughput lead to greater pressure drop. When the battery is discharged at different temperatures, we can see similar characteristics.

With a long running time of increasing demand for products, system designers need a more accurate solution. In a wide range of levels of power demand, gas use battery gauge IC to measure the flow into or out of the battery, get better battery life estimation method.

Principles of battery fuel gauges

Battery fuel gauge is a kind of IC power control system of the battery, making power management system to report on the control processor. Good battery at least takes some steps to monitor the battery voltage, the battery temperature and current methods, a microprocessor and a Dell Latitude D520 battery of evidence of surveillance methodology.

Bq2650x and are complete bq27×00 battery fuel gauge, which is one for voltage and temperature measurements of the ADC (ADC) and a current and a load sensing ADC. The battery meter gas also has a battery monitor to perform calculations microprocessor internal IT. These algorithms will have lithium-ion (Li-ion) batteries self-discharge, aging, temperature and flow rate to compensate. The microprocessor allows the host system processor, without an endless calculations.

Battery fuel gauges offer such as “excess state power” and other information at the same time bq27×00 system also provides execution “surplus time” information. The host at any time that such information could be Asked by the host to decide yes or adoption of the LED screen displays the message to inform customers about the information of the battery. As the system processor requires only 12C or communication HDQ-led, whether the use of fuel gauge of the hp PB994A battery is very simple.

Battery Pack Circuit description

Figure 1 describes the battery in the circuit application. According to the IC gas meter to the battery packs of different batteries have at least three to four are available outside the terminal.

Figure 1 Typical Application Circuit

VCC and BAT PIN to access the battery voltage to the power IC and measures battery voltage. A low resistance value of meaning is installed in the ground terminal of the battery, so the voltage across the sense resistor can be gauges fuel drums in the control of high input impedance to the SRP and NRS. The current flowing through the sense resistor will help us determine the amount of the battery is charged or discharged. Resistance value within the meaning of choice, designers must take into account both ends shall not exceed the voltage of 100mV. The resistance value is too low in the low current conditions may lead to errors. Circuit board layout should ensure that the SRP and SRN to the sense resistor connected as close as possible endpoint for different sensors; this regard Kelvin measurements.

HDQ / SDA and SCL pins are open drain devices, both of which need external pull-up resistor. This resistance must be at the host side or on the side of the main claim, so that the VGP-BPS9/S battery meter to check the operation of sleep in the battery pack and portable devices can be activated after disconnected. Recommended pull-up resistor value of 10K.

Battery authentication

Portable devices, rechargeable batteries must be replaced before the end of life equipment. These offer cheap alternatives to the manufacturers of these batteries have opened a huge market, and these cells may not be a manufacturer of original equipment for security and protection circuits.

Thus, in addition to the features of cell battery gas gauge may also include authentication features (see Figure 2). Host will check that the calculation takes account of cyclical redundancy check (CRC) IC (TI bq26150) battery. The CRC on the authentication database and in the definition of IC in the secret above the CRC polynomial. Home also calculate the CRC, and a variety of value compared to determine if it has been verified. If not, then the host decides to conduct a validation or does not allow the battery systems.

Once the battery through the validation, then the bq26150 will receive the order, to ensure that all lines through the data communications in the host and the fuel gauges of the battery must be transmitted between the two.

This point of view, the host may continue to use the gas from the battery gauge. In disconnecting the battery and re-connected to the batteries must be repeated throughout the audit process.

2 cellular applications

Figure 3 shows the support of two with bq26500 Li-Ion battery typical application circuit. An adjustable voltage regulator was added to the system to achieve the multi-battery. Battery fuel gauges BAT pin is connected to the bottom of the anode of the battery to achieve regulation of measuring the battery voltage.

Host needs fuel gauges measured the battery voltage regulator battery explained that in determining the discharge end of the extinction threshold and cooldown. We can follow the reports of fuel gauge to the battery as the use of “state of surplus electricity and other information.

Conclusion

bq2650x and battery manufacturers bq27×00 offers a simple alternative to the report of the battery. Just from the records of gas from the battery meter to read the data, the host will receive the value of the remaining capacity, then the results displayed to the user. The use of fuel gauge of the battery, end users may be rare in the case of electricity whenever possible by using the loading capacity of the battery as electricity is estimated at more than toshiba PA3285U-2BRS battery voltage is measured only by the available data more accurately. Battery fuel gauge may be used in a variety of structures, which has an audit function, and allows, in many two battery-powered applications to use.

On how to make electric cars have autonomous, there are many suggested, I would like to explore, and we hope that we can say a few words after reading the reviews to see if I am talking about the existence of some reason, good or bad.

Some people say it should be modified for use with the filling, regardless of the number to maintain a daily charge

Some people say it should be used almost re-load, and it is almost! Some say that 50% to 60%, with some saying that 70% -80%, in the end how far, nobody seems conclusive.

Who should we listen?! ! !

Another said the road conditions that the experience of more Daoudi climbing or poor, when leaving the implementation to reduce the discharge current of the VGP-BPS8A battery large, easy to damage the battery. Personally, I think it is not necessary for example! The car came with, is to go around, not to drive people. Moreover, even if the true face of this situation, as you control the improvement of the current size is not controlled by you!?

The following is taken from the network, a number of ways: (red for me to add their own, with or without cause, to your own judge) Subsequently, I will be in the final summing up of other ways you, I am committed to this line of 5 years, believe it or not for people.

1, it should not replace the charger, do not remove the controller, the speed limit.

Chargers each manufacturer are generally individualized demand, not sure that the charger should not be changed arbitrarily. If the mileage requirement for the renewal of a longer trip, you must charge in order to off-site and equipped with multiple shippers, put the charger in the day to charge up the apple A1185 battery charger used to add another while the first wife of charger used at night. Remove the limit of processing speed, although speed may increase the number of vehicles in addition to the safety of vehicles will reduce outside reduces the battery life.

Cons battery charger, and nothing to do with any other component, as long as you use the parameters of a battery charger and the parameters required by consistent for the Chargers and what relationship, we can first select a time yielded good Charger (for example, with a negative pulse, temperature compensation, time limited protection, etc.) is not necessarily the original stuff is better, of course, I have not the excluding all but certain individual Bale. To speed limit this problem, if the above makes sense, but I do not fully support because I use the models of electric bikes Wuyang, 500W power, I have no speed limits, speed is often open to the fastest (up to 50 KM / H), but I use the battery, then a month for two years. Now’s kinda easy to use, but also twenty or thirty miles. (I have my own method of use and cycling, which said I had to do this trip, but I would like to share the back of)

Why a good charger can extend the battery life?

To extend VGP-BPS10B battery life, more habits and riding a charger quality of the battery, plus the quality is good or bad. On the one hand, if the battery is simple in principle, but has its own fresh discharge performance characteristics (part of the charge and discharge processes are taking place in a complex physical and chemical changes), and only compatible with this method of pricing, and repair the charger with pulse can be truly meaningful to prolong battery life, the other hand, chargers and battery chargers together almost every day, not in accordance with feeder lines battery, this means that the battery is “the killer pillow,” “slow poison”, overload or under load will be long “term poisoning ‘of battery, a long time, prone to water loss, affect the deformation bulge the normal life of a battery problem, which is the industry has often said that the battery “is not used or wrong, is filled with bad argument”.

2, protecting the Chargers.

Manual of Policy for the protection of both the shipper’s description above. Many users do not have the habit of looking statement, often out of the question after he came to find manual to see, too late, then look at the manual is very necessary. To reduce costs, the charger current essentially made no high-vibration resistant design, so that shippers generally do not put your electric bike in the trunk and the car. Special circumstances, we must move forward, we also need the charger supplied with foam to prevent vibration bumps. After a lot of vibration through the charger, its internal potentiometer will drift, which makes the whole drift parameter, resulting in an abnormal state of charge. Also noteworthy is the charge when the hp PB991A battery charger to maintain ventilation, otherwise not only affect the life of charger may also be affected by the thermal drift has produced the state of charge. This training will damage the battery. Therefore, to protect the battery charger is also very important.

Plus I do not judge, but they would add is preferable not to board charger, because the quality of vibration inside the Council to make relatively large components such as transformers, capacitors, high power transistor, FET adjustable potentiometer so cowardly took place, resulting in the parameters of the charger drift, or even damaged. But too tight, electronics is something similar – fear of water.

3 daily charge.

Even if your skill needs for the renewal of lines not long in charge of a battery can be used 2-3 days, but it is recommended to charge a daily basis, so that the battery in a state circular shallow, the battery life will be prolonged. Some of the early use of mobile phone users thinks the best is the basic use of the battery charging is completed, this idea is false, the memory performance of lead acid battery is not so strong. End of regular exercise impact Dell Y9943 battery life of power is relatively large. Most of the direction indicator light changes charger after full charge recharges the battery to power in May of 97% ~ 99%. While the charge is due only 1% ~ 3% of electricity lines on the continued ability of these effects are almost negligible, but it will also occur due to the accumulation of charge if the battery is fully charged, after changing the lights, or floating charge as much as possible to continue to contain sulfide battery is also be beneficial.

If you want to use more battery power, then, do not ask every day! Electric cars recharge the battery should not be frequent, because the battery charge and discharge cycle is certainly several times, usually in 300 or more, often to charge the battery will increase battery cathode active material for soften the edge of falling will result in accelerated grid corrosion. Each time you conjure, which is equivalent to reduce your battery life, if manufacturers or distributors, they say, because it can do, the battery could practically have the warranty period, the Life expectancy is almost over a month or two, two three months away. Should be used in almost re-load, of course, can not be too long, you said that I was sitting too low, 10 days and half a charge that does not, in general, we should charge a maximum of 23 days. Unless you think you are using the remaining capacity is not enough. To see how almost better behind the summary.

4, a charge timely.

After the 40Y6797 battery discharge process of healing began in the 12 hours before departure, there is a clear cure. In due course load, you can remove the sulfide is not serious, if not promptly charged, these crystal paperweight will gradually accumulated to form crystals of thickness, the average of those bulky chargers crystallization is impotent, and will gradually decline in battery capacity and reduce the life of the battery. Therefore, in addition to charging every day outside, but also noted that the use should be ended as soon as possible after charging, battery power as much as possible in a full state.

Charging time is also considered bar not entirely wrong, someone may ask, do not you have mentioned above, almost did not want to use? In fact, no contradiction, that is, if you can, you’re used to remember that, after almost a payload, whether or not we should charge a timely manner. And I mean both “non-recurring charge is not really a burden in time. The best half an hour to sit for an hour after the load (or battery capacity does not disintegrate may be an exception). Why? compatibility of the error because the problem of factory batteries / long used (with history of tension, a large load, etc.) / load reasons (not the law of charge ), so the imbalance between different cells, which is a group of cells that had point undervoltage protection already at 10.5 or less, while others were pricey Tingduo voltage electricity. If the point charge, charge in electricity is the same, but when used makes the difference due to the time of unequal power and even intensified. finally led to a period less than the normal BATCL50L battery is too low cure serious damage. If you put aside for 0.5-1 hours, then charge the battery will gradually establish a balance of power (that is, you will see that after each use to stop gauges fuel rises yet), though the problems quickly by this method on the battery still have some repair work. However, a better way to address this problem are: the repair of a separate charge. If you find that your mileage is less than 70% of lines were added in the case of the exclusion of other issues, you can test the capacity of the battery meter and repair problems with the battery, you can greatly extend the lifespan battery.

5, periodic deep discharge.

The battery on a regular basis to conduct a deep discharge is also conducive to “active” batteries, you can slightly increase the battery capacity. The general approach is to periodically conduct a fully discharged battery. Fully discharge method is a flat surface under conditions of cycling normal load protection Undervoltage first. Note that we have focused on protecting the first time under tension. Battery protection under-voltage in the first after the battery over time, the tension will increase, but also to make a non-state voltage, this time, if the re-use batteries, the battery would seriously injured. After completion of completely discharged, the battery is fully charged. Feel the battery capacity has improved.

It was just, but are not intended to be the first time then. Remember to “load time”, while the cycle, since long, see the summary.

6, to develop good savings habits.

Whenever possible, the use of slides. The slope, where the use of technology as slippery as possible slowdown. When the fire in the next meeting early entry into the taxi, to minimize braking. A friend told me he was ready to be transferred once a bay must be reduced once the brakes, it is justified. Start time, the best help reach the turn can not only improve the startup speed, but may also reduce the battery life of power loss and damage.

The car driving the process should not begin to be frequent braking because the brake and then start the vehicle over, especially in the early hours of the mainstream, in a period of free time is equivalent to restrictions size value

7, pay attention to the pricing environment.

Charging the best environment temperature is 25 ℃. Most shippers are not adapted to the temperature control system automatically, so the majority of shippers are designed according to the ambient temperature 25 ℃, then the load at 25 ℃ under the conditions better. Otherwise, it is inevitable that winter and summer due to off-load problem free. The ambient temperature at 25 ℃, when the real is relatively small, so there must have been winter because of the statement of the problem of overloading. Fortunately, most families now have the conditions of indoor thermostat, so that charge, the best settings for VGP-BPS10 battery and charger and the thermostat in a well ventilated place. Special note is the battery in the northern state of winter outdoors in the room temperature when the hot surface of the battery is frozen gel. To avoid battery leakage caused by freezing freeze if the battery temperature increases to room temperature to near dried with a charge later.

Note: The battery charge voltage and ambient temperature is inversely proportional to the relationship between

8, make full use of the state of maintenance

Many dealers can supply electric bicycle battery maintenance and repair services, should take full advantage of these services. Some brands of electric bikes is the maintenance of the battery. Such as regular maintenance of batteries can reduce damage to the battery. The battery state of charge of the repair can alleviate the battery “back” of failure, which is equipped with a capacity to maintain the dealer is easy. For dehydration, the battery capacity of 70% capacity recharge battery to 40% of the time when the effect of replenishment of better quality. And even some brands are also available: the deadline will not repair equivalent to waive the warranty period the battery. In order that consumers should not have gone through this loss. Therefore, consumers should be fully used to expand the conditions for maintaining the VGP-BPS9/S battery to increase the lifespan of the battery.

With these methods, the user can greatly extend the battery life. Some users of the continuous line mileage relatively short, the battery life is relatively long, some problems are relatively difficult to detect. Accordingly, Article 4 says the landfill “profound” measures to detect the problem of the battery are also an effective way, not a serious problem, as when the battery is difficult to treat.

Sanyo Electric Co., Ltd., the world’s largest battery manufacturer, has at least two customers lithium-ion battery powered plug-in hybrid cars won, an official said.

The company will begin a cell vehicle, including the Japanese auto manufacturers and overseas, as in the second half of 2011, “the head of the mesenchymal Sanyo Dell Inspiron E1705 battery group, yesterday in an interview that the company is in Osaka, western Japan Headquarters. Honma no fixed customers.

The latest electronics manufacturer Matsushita acquisition is to accelerate the development of lithium-ion battery plug-in hybrid vehicle in the expected growth in demand for vehicles and reduced emissions. The company estimates that global sales of hybrid cells using lithium-ion battery, which will increase to 2 million in the year 2015 7.48 million in 2020.

“Lithium-ion batteries used in cars to a winner on the rapidly growing market, Sanyo has been paid, the core of the corporate strategy,” said Nobuo Kurahashi, an analyst at Mizuho Investors Securities in Tokyo. “Such an agreement is a very positive development.”

Most hybrid cars currently use nickel-metal hydride VGP-BPS10A batteries, and automobile manufacturers are trying to develop plug in models and electric vehicles using lithium-ion batteries are lighter and stronger, but they were more expensive than the models Nickel metal hydride.

Sanyo fell 1.9 percentage points to ¥ 156 from 11 clock trading break in Tokyo Stock Exchange to expand its dropped to 6 percent this year. The Nikkei 225 index fell 0.2 percent today.

Toyota, General Motors Hybrid

To build Toyota Motor Corporation, manufacturer of the automotive world’s most popular hybrid, Prius, plans, a model of the plug-in retail customers in 2012. General Motors Corp. is planning a 60,000 Chevrolet Volt plug-in electric vehicles than a year in November 2010 to build.

Sanyo Electric Co., Ltd. plans to offer lithium-ion battery powered plug-in hybrid vehicles in Toyota, Japan’s Asahi Shimbun, 21 October, there is no doubt where she received the information. Honma Hideaki Toyota spokesman today refused to confirm or deny that Sanyo’s suppliers.

Worldwide sales of lithium-ion VGP-BPS9A/B batteries to 2.0 billion yen (230 billion U.S. dollars to achieve) in 2020 to ¥ 84,000,000,000, in 2008, estimates the demand for fuel cells in electric vehicles and hybrid cars, Daiwa Institute of Research, used in January. Lithium-ion batteries can be more than the nickel-metal hydride batteries in the car market in 2014 or so, says the researcher.

The future is plug-in

Plug-in hybrids will be the engine of growth pattern of low-emission vehicles in the years to fully develop the new technology batteries, motor vehicles and charging stations by power driven, said Honma. “Around 80 to 90 percent of environmentally friendly vehicles in 2020 will likely be either male or mixed.”

Sanyo can make any 300000-400000 per month if these cells in 2011, began with the production of its new nuclear power plant under construction Kasai said Hyogo Prefecture, western Japan, among these, in October.

Battery manufacturers are planning to build factories in Europe, China and the United States in 2012 began producing car VGP-BPS9/B battery module, the international told a press conference in October.

Sanyo production of vehicle in Japan, to reduce transportation costs, the battery plant foreign auto plants in the vicinity.

Prices declined slightly since

Average cost reduction for lithium-ion batteries for electric and hybrid vehicles by half by 2014, research organizations, economic groups, “said Fuji, 6 November. The technological development and mass production can reduce costs in the global market for lithium-ion vehicles to 2.25 million yen in 2014 until 2, 5 billion yen this year, according to researchers.

Automobile manufacturers such as Mitsubishi Motors Corp. The goal is to reduce the purchase price of electric vehicles in order to stimulate demand.

Nissan CEO Carlos Ghosn says electric car in August will be provided by at least 10 percent of global demand by 2020, which include the cost of oil more than $ 70 per barrel. Nissan will start selling electric cars in the next year to leave.

Sony negotiated supply “several companies” with lithium-ion battery car, Executive Vice President Hiroshi Yoshioka said last week refused to identify potential customers. Yoshioka 19th November, said Sony plans ¥100000000000 research and development of rechargeable batteries, electric cars, and invest so on.

“The plan is natural that Sony in this market because of high growth potential type,” said Honma. “With or without competition from Sony in this market, both technical as well as prices will strengthen.”
