Introduction to maintenance methods of lithium-ion battery in battery car in winter

First, pay attention to the charging method, and try not to charge the battery under the ultra-low temperature standard. The high temperature is the same. When the high temperature exceeds 30°C, the charging must be added to the current amount. Second, when charging in winter, you can use the method of charging a few more times. When the battery is hot, you can charge more at one time. Third, maintain sufficient power. In winter, when the battery is charged and discharged more than 50%, the lithium-ion battery electrolyte will have the risk of freezing. Therefore, the battery should be maintained at more than 50% of the power consumption in winter. . Fourth, start the car every time and charge it. It is not necessary to overcharge and discharge the battery, and it is not necessary to let the pure electric vehicle sit idle for a long time outdoors in winter. In this way, I firmly believe that everyone's lithium-ion battery car may be safer than this winter. 2. During use, if the continued mileage of an electric vehicle suddenly drops more than ten kilometers in a short period of time, it is very likely that at least one battery in the battery pack has broken grids, softened plates, and fallen off of active materials on the plates, etc. Short circuit phenomenon. At this time, you should go to a professional battery repair organization for inspection, repair or assembly in time. This can relatively extend the life of the battery pack and save money to the greatest extent. 3. When the electric vehicle starts, carries people, or goes uphill, please use the pedals to help prevent instantaneous high current discharge. High-current discharge can easily lead to the appearance of lead sulfate crystals, which will damage the physical properties of the battery plates.
