How to maintain the battery of an electric car?

When driving, when the electricity meter indicator lights up in red and yellow, it should be charged; if only the red light is left, stop driving immediately and charge as soon as possible. Excessive battery discharge will seriously shorten its service life, which is not what car owners like. All things must pay attention to moderate, over-discharge can not be achieved, some car owners are afraid of insufficient car supply, desperately charging the battery is not the right behavior. Under normal circumstances, the battery charging time is about 10 hours. During the charging process, pay attention to the battery temperature not to exceed 65°C, which is also a good way to protect the battery. In addition, the maintenance experts also told the author of Guazi second-hand car that if the battery can be deeply discharged on a regular basis, it will be beneficial to activate the battery and can slightly increase the capacity of the battery. And it is recommended to charge the electric vehicle every day to keep the battery in a shallow cycle state, which can extend the battery life. 2. The protection of the charger's power transmission can rely on this charger, so don't neglect its maintenance. For the charger, attention should be paid to prevent the charger from jolts and vibrations and to maintain ventilation and heat dissipation. After many chargers have undergone substantial bumps, the internal potentiometer will drift, causing the entire parameter to drift, and the charging state will naturally be abnormal. 3. Loss of electricity storage is a big taboo. If the pure electric vehicle in the home is to be idle for a period of time, it is important not to maintain a certain amount of electricity for storage. When stored under power shortage, sulfation will occur, and lead sulfate crystals will adhere to the electrode plates, and the ion channels will be blocked, causing the battery flow to drop. The result that the car owner can see directly is that when you use it again, I'm sorry, it goes on strike. Therefore, when car owners leave their electric cars idle, they must charge them once a month to keep the batteries in good condition. 4. Prevent high-current discharge. When driving a pure electric vehicle to start or go uphill, the owner should step on and accelerate as much as possible, otherwise a high-current discharge will occur, which will also lead to the appearance of lead sulfate crystals and affect the performance of the battery plate. 5. Use the controller well. The protection voltage of the controller should be slightly greater than the battery protection voltage, otherwise, the battery will be over-discharged.
