Electric vehicle battery maintenance

Electric Vehicle Battery Maintenance Electric power is one of the vehicles commonly used in our daily life. Electric vehicles are favored by consumers because of their advantages such as light weight and no pollution. The length of driving mileage is the main criterion for consumers to measure the quality of electric vehicles. one. It is worth mentioning that in many electric vehicle quality complaints, the battery problem accounts for more than 95%, because the battery is an important factor in determining the length of the electric vehicle. Then electric car battery maintenance should pay attention to what issues?

Loss of electricity during storage is strictly forbidden - storage batteries must not be in a lossy state when they are stored. Loss of power status means that the battery was not charged in time after use. When the battery is stored in a depleted state, sulfation is likely to occur. Lead sulfate crystals adhere to the plate, blocking the ion channel, resulting in insufficient charging and decreasing battery capacity. The longer the idle state is idle, the heavier the damage to the battery. Therefore, when the battery is not used, it should be recharged once a month, so that it can maintain the battery health.

Regular inspection - In the course of use, if the mileage of the electric vehicle suddenly drops by more than ten kilometers in a short period of time, it is very likely that at least one of the batteries in the battery pack is broken, the plate is softened, and the plate active material is peeled off. Such as short circuit phenomenon. At this time, it is necessary to promptly go to a professional battery repair facility for inspection, repair or matching. This can relatively prolong the life of the battery pack and maximize savings.

Correctly grasp the charging time - in the use process, should accurately grasp the charging time according to the actual situation, with reference to the usual frequency and mileage, but also pay attention to the size of the battery manufacturers to provide instructions, and the matching charger performance, charging current size Other parameters to determine the frequency of charging. In general, the batteries are charged at night and the average charging time is about 8 hours. If the discharge is shallow (the mileage after charging is very short), the battery will be full soon, and over charging will continue to occur, causing the battery to lose water, heat, and reduce battery life. Therefore, the battery with a discharge depth of 60% -70% when the first charge is the best, the actual use can be converted into riding mileage, according to the actual situation of the necessary charge, to avoid harmful charging.

When starting, it is best to pedal first - riding an electric car is not too much trouble, it is best to start with a pedaling, then slowly accelerate. The battery is afraid of heat in the summer and must not be exposed to open flames. Avoid direct sunlight. Use the charger to confirm the model, voltage and frequency to meet the requirements.

Every 2 months, deep discharge once and deep charge once.

Matters needing attention: Do not wait until the battery is exhausted before charging, so easy to put the battery "dead." In addition, if the vehicle is not used for a long time, it must be filled with electricity, otherwise the battery will “starve to death”.
