The maintenance of lead-acid batteries for electric vehicles should remember these eight points

The battery manufacturer’s technicians revealed: In the maintenance of lead-acid batteries for electric vehicles, remember these eight things. Batteries are the key to the maintenance of electric vehicles. Regarding the issue of battery maintenance methods for electric vehicles, of course experts’ opinions are more reliable, so the author consulted with battery technology experts and finally got the following suggestions. 1. If you are on a long-term business trip, what should you do when you don’t have batteries for electric vehicles? The batteries must be fully charged after storage, and the battery must be recharged after each month, so as to avoid the storage of batteries for a long time and cause the batteries to be caused by sulfuric acid. Decrease the battery capacity or even scrap it. Therefore, when the battery is not in use, it should be replenished once a month to keep the battery healthy. 2. Regularly check the battery during use. If the driving range of the electric vehicle suddenly drops by more than 10 kilometers in a short time, it is likely that the grid of at least one battery in the battery pack is broken, the electrode plate is softened, and the active material of the electrode plate is short-circuited. phenomenon. At this time, you should go to a professional battery maintenance organization for inspection, repair or grouping in time. This can relatively extend the service life of the battery and save energy to the utmost extent. 3. Prevent high-current discharge. When the electric vehicle starts, carries people, or climbs a mountain, please use your feet to push the power and try to prevent instantaneous high-current discharge. High current discharge can easily lead to lead sulfate crystallization and damage the physical properties of the battery panel. The battery manufacturer’s technical personnel revealed: The maintenance of lead-acid batteries for electric vehicles should remember these eight things. 4. Correctly control the charging time. During use, it is necessary to accurately grasp the charging time. According to the actual situation, refer to the usual frequency of use and driving. At the same time, pay attention to the capacity of the battery manufacturer to regulate the supply, as well as the performance and support of the charging of the charger. Generally speaking, the average charging time is about 8 hours when the battery is charged at night. If there is a slight discharge (the driving range after charging is very short), the battery will be fully charged soon, and the battery will be overcharged if it continues to be charged, which will cause the battery to lose water, heat, and reduce the battery life. Therefore, it is best to charge the battery when the depth of discharge is 60%-70%. In actual use, it can be converted into riding mileage, and it is necessary to charge according to the actual situation to prevent harmful charging. 5. What should I pay attention to when using electric vehicles in summer? 1) Prevent exposure to the sun, and do not charge in high temperature environments; 2) Prevent charging immediately after high temperature driving, and prevent excessive charging time (about 8 hours); 3) Battery charging If the power box is hot or does not turn green, you should go to the battery shop or our company's after-sales service outlets to test and maintain the battery or charger in time. 6. Preventing the charging plug from heating up. The output plug of the charger is loose and the contact surface is oxidized, which will cause the charging plug to heat up. Excessive heating time will cause a short circuit in the charging plug, which will directly damage the charger and cause unnecessary losses. Therefore, when the above situation is discovered, the oxide should be removed or the connector should be replaced in time. 7. When is the best time to charge the electric vehicle battery? When the electric vehicle battery indicator pointer is at or near the lowest position, the electric vehicle charging effect is the best. Conducive to the life of the battery. If the riding mileage is less than 5-10km per day, it is recommended not to charge, that is, do not shorten the riding mileage, and charge frequently. Otherwise, the battery life will end prematurely. 8. Can the charger be carried with me? No, the road vibration of the electric vehicle is uneven during use. If the charger vibrates, its component parameters will drift, affect the charging performance, and even damage the battery (charging or rechargeable drum battery). Therefore, The charger is not allowed to be carried with you. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
