How to charge the lithium battery of electric vehicle correctly

Under normal circumstances, a lithium battery is in a low-capacity self-discharge state from the moment it leaves the factory. After the battery is left for a period of time, it enters the dormant state. At this moment, the capacity is lower than the normal value, and the use time is also shortened. The capacity loss caused by self-discharge is reversible, which means that it can be recovered by charging the battery. Some people think that when the lithium battery is activated, the charging time must exceed 12 hours, and it can be activated after repeated charging three times, but in fact this is a great misunderstanding. After all, overcharge and overdischarge will cause different degrees of harm to the lithium battery! However, it is worth mentioning that the lithium battery is very simple to activate, and no special method is required. Generally, the battery can be activated after 3-5 normal charge and discharge cycles to restore the normal capacity. 2. When to charge the lithium battery Many users think that when the electric vehicle is dead, they will charge the lithium battery. After all, the number of charging and discharging of lithium battery is limited, so the lithium battery should be exhausted or used up to recharge. Under normal circumstances, the battery should be used up and recharged. However, although the electric vehicle still has a certain amount of power remaining, but can not be satisfied with the next day's itinerary, then it is still necessary to charge that night. However, if the electric vehicle is too low in battery power, if the electric vehicle is forced to travel at this time, the voltage may be too low due to the over-discharge of the battery, which will endanger the life of the battery. 3. Summary of Lithium Battery Charging It can be seen that the activation of the lithium battery of electric vehicles does not require a special method, and it is charged according to the standardized time and procedure. In the normal use of electric vehicles, the lithium battery will be naturally activated; when the electric vehicle shows a warning that the battery is too low, it should start charging in time.
