How to maintain the battery of electric vehicle?
It took the car a year to find out, and the biggest expense was the battery. A set of lead-acid batteries 3, 400 yuan, up to more than a year on the scrap, and really some heartache. Can not let the battery run more than a few years? Certainly! This country, protect the environment good, ten years ago many people had studied.Electric vehicle battery is traction battery, and other batteries are different, we ride the electric car want to ride faster, far away, charging is not convenient, with the charge, charging time want a little shorter. Therefore, the discharge current of the battery of the electric vehicle is larger, the discharge depth is deeper, the charging current is larger, and the charging interval is longer. This makes the battery performance quickly damaged, seriously affecting the battery life.
How to prolong the service life of battery?First, the car to light, better performance. Using simple models of battery life style is relatively long, because the wheel diameter, light weight, battery light burden. And some cars using brushless motor or high-speed motor, discharge current is smaller, such a car at 20 kilometers per hour cruise current is about 4a, this kind of car life is relatively long.Second, the battery should choose a good quality brand.Third, choose a good charger. The popular phrase is: battery is not bad, is full of bad. Therefore, the charger should be used well.
Fourth, the car does not use batteries for a long time, a Zhou Chong, a power. (for two or three months without recharging, the battery is going to waste.)Fifth, cycling should pay attention to, generally take the start, climbing, manpower help line, without overloading, do not drive fast, often charging.Six, battery vulcanization is the first killer of battery life.Vulcanization is a battery that produces lead sulfate particles during charging and discharging, especially in large current discharges. For example, if the 10Ah battery, with more than 10A current discharge will produce more lead sulfate particles in cathode materials, this reaction is irreversible reaction in electric current conditions and charging mode, with the extension of time, the particles in the electrode material on the accumulation, because the particles are not conductive, the resistance of external characteristics of the show is to increase the battery, reducing the capacity, cause the whole group battery capacity decline, large current discharge capacity (the actual performance is climbing ability) to further reduce. This phenomenon is called the vulcanization of a battery. Once the battery is vulcanized, it will not only reduce the capacity of the negative plate of the battery, but also aggravate the loss of water and the softening of the positive plate, which will affect the life of the whole battery.
