In power battery electric vehicle with the theme of the third period zhongguancun technology Sharon today, this afternoon to promote cell and automobile research docking for the purpose of power battery industry association and approved.
The science and technology committee and the municipal administration committee of zhongguancun science park, new energy technology companies, electric power company and auto enterprise insiders “Beijing electric car industry development planning,” “intelligent network in Beijing electric car battery pile in construction planning needs” and “power battery in the application of new energy vehicles industry” power battery and hot topic in the automobile made special.
Shallum, the clean in automobile action coordination leading group office WangBingGang research group made titled “China electric car industry status and development strategy” theme report. WangBingGang said, the current domestic research progress of pure electric cars, and the advanced international level is very close. He said China’s energy, the key to the development of automobile development, the future depends on batteries, a lighter weight, cheaper and more advanced technology of the battery will be born to replace the current battery energy storage device drivers and hydrogen fuel driver, become the new energy vehicles driving mainstream.

Many owners think battery is a very simple, usually also don’t pay much attention to make maintenance, actually in the car for daily use, the battery is one of the most important part is that cannot be bothered.

The daily use battery should pay attention to? The reporter interviewed specially evergreen battery Co., LTD, deputy general manager ZhouYongJian and guangzhou wide males born industry &trade Co., XuJingXiong general manager. ZhouYongJian battery has started, said the battery and batteries, and start again, including free maintenance batteries battery and “water” battery. Is the commonly used car, are start-up battery, because it can make automobile accumulator, then an instant cast, so that with good quality, the start-up and start batteries more quickly.

Brand battery guaranteed.

The rechargeable battery

One of the following conditions should charge: the electrolyte proportion fell below 1.2, Winter discharge more than 25%, Summer more than 50%, discharge, Lights dim, Start weakness.

Some owners think fast charging, can save time, need only 3-5 hours. Actually otherwise, fast charging the battery is rapidly, but actually surface activation is not completely filled with internal battery power.

Besides rapid charging, and a slow, charging for charging for 10-15 hours, the deep kui battery charging, must carry out slowly enough time, rechargeable battery or insufficient quantity, will directly affect the automobile driving performance. Although charging a fairly simple operation, but also has some precautions: 1. To lead-acid battery, will wear protective clothing. 2 when the battery charging, near sparks, smoking is not. 3 for one or more storage battery in parallel, charger 16V don’t exceed voltage.

In the use and maintenance of relevant battery need some problems:

1 long battery, it will not, by slowly. Until the discharge, Therefore, every time should start a car, for battery. Another way is to be drawn on the battery electrodes, should pay attention to the electrode plucked from pillar to the positive and negative electrode wire to root out, or unload line under negative anode and automobile chassis connected. Then with a positive sign out (+), on the other side of the battery has certain service life, to certain period should be replaced. In the same order, but should follow the above the electrode connected up in order, in contrast, first, and then pick up the positive anode.

2 when the ammeter pointer indicates that power is not enough, storage battery timely. The storage battery power can be reflected in the dashboard. Sometimes, the way of the engine that enough power, and can’t start, remove provisional measures as to other vehicles, can help with their vehicles to launch vehicle, storage battery anode and cathode two, positive and positive.

3 the density of electrolyte, should according to the different regions, different season, according to the standard for the corresponding adjustment.

4 in the kui electrolyte should supplement distilled water or special rehydration. Do not use drinking water instead. Because water in contains many kinds of microelements, adverse impact on batteries will.

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.

The concept of electric vehicle in early 20 years ago, the people are always looking forward to electric car could come as soon as possible, but when electric cars can enter homes in Frankfurt, auto also see specific date.

Volkswagen company board of directors wally, technology in answering reporters hawking berger inquiry, expected to 20 to 30 years, electric cars can freely on highway, but this period, automotive engineers need to electric car constant improvement. In the auto, many famous auto manufacturers, such as Benz, BMW, mass, etc. Are introduced, the Peugeot Citroen of electric cars, but these are calculated, and the exhibition has not the shape of the car to mass production. The car was calculated and finalize the biggest difference is calculated, can not consider manufacturing cost, not even consider using life, but to finalize the car, cost and life is the key of the two indexes, otherwise the market couldn’t accept.

Current electric car into the market of the influence factors or technology, which is the key of the rechargeable battery performance. According to the automotive expert introduction, now the best rechargeable batteries in high-speed vehicles condition, use a few minutes, the battery will be exhausted, so also insufficient trekking and highway driving. The performance of the best international lithium battery charge weight from 10 per KWH to drive a car kilograms, similar to the micro car, like QQ will need to 20 KWH of power, this makes the corresponding the bulk and weight of rechargeable batteries, automotive extra weight weighed 160 to carry 200 kilos of lithium battery, and this is the convert electric energy is only 2 litres of fuel gas! Some manufacturers introduced its electric car battery can drive a hundred kilometers, in fact this is in urban road, and must be low in electric car ideal work environment, such as temperature cannot too high or too low, vehicles cannot open air conditioning, etc.

Restrict the development of electric vehicle another factor is the cost of rechargeable batteries. Now a 20 KWH cost of lithium battery is about 2 million euros, if the battery to mass production, of course, still can reduce cost of at least 1/3. It is hoped the automobile manufacturers. The battery must be in the current level of performance to improve on three times, the price to reduce 2/3, so that there may be a market competitiveness. Toyota motor corp. In the development of electric automobile aspect, it is the most advanced and use the invention, namely so-called hybrid engine technology with electric motor fuel engines, the volume of rechargeable batteries can be smaller. Is this hybrid engine vehicles driving around 20 kilometers, when, after the rechargeable battery power will deplete. This will fuel, and travel time in the transformation of energy into electricity will part for charging the battery,. Toyota hybrids in the market has sold nearly a million cars, but strictly speaking, it is not 100 percent of the electric car.

And the history of the development of electric vehicle with Japan, but really sold on the market of the electric car is small, at least a few German automobile manufacturers, such as mass, Benz, BMW are no formal sales over a car electric cars. The car company every year in international auto show will launch a new electric car models, but basically is doing publicity. Such as the Frankfurt motor, Mercedes launched 392 kw series power electric car, athletic E audi car company has introduced a series of R8 electric car. The highest The two cars are adopted, the third generation of Hybrid technology is in Hybrid technology Plug, this generation of Hybrid technology battery can already through external socket, and in charge of a journey in the use of electricity, after running out of energy will be converted to fuel engine.
Carmakers is the development of the next target no fuel engines, fully sense of electric cars. Achieve 100% of the electric car key, so far, or the rechargeable battery technology will have greater breakthrough.
