Battery maintenance.18650 lithium battery cells

　　1： It is strictly prohibited to lose power during storage

　　It is strictly prohibited to store the battery in a state of low power. Low battery state refers to the failure to charge the battery in a timely manner after use. When the battery is stored in the state of power loss, sulfation is easy to occur, and Lead(II) sulfate crystals attach to the electrode plate, blocking the electric Ion channel, resulting in insufficient charging and reduced battery capacity. The longer the idle time in a low power state, the more severe the battery damage. Therefore, when the battery is idle and not in use, it should be recharged once a month to better maintain the healthy state of electric vehicle battery maintenance.

　　2： Regular inspection

　　During use, if the range of the electric vehicle suddenly decreases significantly in a short period of time, it is highly likely that at least one battery in the battery pack has a short circuit phenomenon such as broken grid, softening of the electrode plate, and detachment of the active substance on the electrode plate. Therefore, it is necessary to promptly go to a professional battery repair agency for inspection, repair, or assembly. This can relatively extend the lifespan of the battery pack and maximize cost savings.

　　3： Avoid high current discharge

　　During the use of electric vehicles, try to avoid instantaneous high current discharge. High current discharge will easily lead to Lead(II) sulfate crystallization, which will damage the physical properties of the battery plates.

　　4： Mastering charging time

　　During use, it is necessary to accurately grasp the charging time based on the actual situation, refer to the usual frequency of use and mileage, and also pay attention to the capacity specifications provided by the battery manufacturer, as well as the performance of the supporting charger, the size of the charging current, and other parameters to grasp the charging frequency. Generally, batteries are charged at night, with an average charging time of around 8 hours. In case of shallow discharge (the driving distance is very short after charging), the electric Automotive battery battery will be fully charged soon, and overcharge will occur if the battery continues to charge, resulting in water loss, heat generation and reduced battery life. Therefore, it is best to charge the battery once when the discharge depth is between 60% and 70%. In actual use, it can be converted into cycling mileage, and necessary charging should be carried out according to the actual situation to avoid harmful charging.
