Battery frequently with diligence is filling, basically means everyday ride a charge, but after they have a problem here is that if you can run the battery, 30 kilometers, running 5 miles or 10 kilometers to it, not for battery charging is good, because when batteries electricity, gas will overflow, and the gas, water is electrolyte of decomposition, such loss occurs frequently, so the battery charging, dehydrate number increase, the battery will quickly into the expiration date.

So the best method is if you don’t ride motor, you’d better put it full of electricity, but when you ride a 5 kilometers or 10 kilometers, the next day after the journey is enough to run, is the best day after riding, etc, so the battery recharging dehydrate, the battery life is extended.

In addition, for some batteries can run 30 km bike every day, but in 7, 8 kilometers, had better not etc on the third day after day or electric batteries are riding in battery charging again, is less than half the time was left in charge, because the battery power is not enough time deposit, easy to produce sulfide.

In addition, every month, had better be the battery power after a one-off, namely the battery voltage to ride, deep discharge of a battery charging, it can prolong the life of the battery.

In addition, there is little in charge, insert the plug first battery, one 220V utility. At the end of the battery, and then pulled out 220V mains battery charger, when the plug turn lights turn green again, can one to two hours of rechargeable batteries have filled, not just a filling, charging overnight overcharge for battery charging and very serious damage. Remember remember!!!!!!!!!!

In addition, electric batteries used often and battery life is relatively long, also said, not with you everyday, the battery will fear you for a long time

In the 63rd annual international motor show in Frankfurt, Germany, on September 17-27. In the global financial crisis, the world economy is just not recover situation, the cars have exhibitors with friendly to environment characteristics of new energy vehicles for the window, as the most outstanding is all kinds of electric cars.

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.

Forbattery, maintenance, car battery is an indispensable part of the market, according to the existing battery varieties can be divided into two kinds: the traditional lead-acid battery and domestic popularity in recent years in the WeiHuXing free use of battery.
Lead-acid battery consists of plus or minus plate, partition, shell, electrolyte and wiring components, the discharge or the chemical reaction is depend on is alive and negative plate material plate material in electrolyte live dilute sulphuric acid solution () function, including plate under the lead of antimony alloy frame is made. Traditional battery in use process will happen, and this is the phenomenon of liquid reduction due to the gate of antimony can lead pollution on the plate, negative caused by excessive decomposition, a large number of water from negative oxygen and hydrogen to the plate to escape, electrolyte.
Battery is used calcium alloy manufacture, due to lead the battery using lead calcium alloy bars, so do the charging water quantity is little, water evaporation and low, plus the sealing structure, releasing the sulfuric gas is rare, so it is compared with the traditional battery, without adding any liquid, head of wires and cables, corrosion resistance, less body charging ability, starting current power stored for a long time, etc, in recent years in China is very popular.
The following is in use and maintenance of 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.
5 the car, without intermission to use to start by excessive discharge and damage to the battery. The correct use of time to launch vehicle is time – not more than 5 seconds, restart interval of not less than 15 seconds. In times of the car is not start from the situation, oil circuit ignition coil or other aspects for reason.
6 daily traffic should check whether the cover the holes. If the battery cover the holes blocked, produce hydrogen and oxygen to row, electrolyte expands, the battery can be broken shells, affect battery life.
7. Check the battery of positive and negative level without oxidation signs. Can use hot runner battery wire connection often.
8. Check without aging or circuit each part of the circuit. Avoid excessive discharge and early retirement because.
