    What does battery equalization mean?

    The battery pack consists of several lithium batteries, each of which has its own cut-off voltage for charging and discharging. For example, the charging cut-off voltage of 18650 battery is about 4.25v, and the discharging cut-off voltage is about 2.75V. Generally, as long as a lithium battery reaches the cut-off voltage, for the protection of the battery, the charging and discharging process will be terminated.

    During the charging process, other lithium batteries may not reach the charging cut-off voltage, only one lithium battery has reached the charging cut-off voltage. But for the protection of the battery, the charging process will end. This is just like the barrel principle, because a "short board" leads to a big discount in the storage capacity of the whole barrel, and the unbalanced battery will lead to a serious reduction in the endurance mileage.

    In the discharge process, only one lithium battery may reach the discharge cut-off voltage first, and the rest lithium batteries have a lot of discharge capacity, but for the sake of protection, the discharge process will also be terminated.

    When the range of pure electric vehicles is seriously reduced and the power is not sufficient, 4S stores usually use equalizers to "balance the battery" for vehicles. The purpose is to balance the charge and discharge performance of all lithium batteries to the same level as much as possible, so that the battery pack can store more electric energy and discharge more thoroughly.
