一种电池组放电均衡控制电路
摘要：
本申请公开了一种电池组放电均衡控制电路，所述电池组包括至少两个电池单体，包括：输入端分别与至少两个所述电池单体相连接的电压检测电路；输入端与所述电压检测电路的输出端相连接的电压比较器；与所述电压比较器相连接的控制器；与所有电池单体均连接的放电电路。该控制电路在电池组放电过程中，可以保证电池组之间的电压均衡，避免由于电池单体之间的差异而导致电压不一致的问题，进而可以延缓电池组容量减小的情况，且可以提高电池组的使用寿命。
摘要（英）：

The application discloses a battery pack discharge equalization control circuit. A battery pack comprises at least two single batteries. The battery pack discharge equalization control circuit comprises a voltage detecting circuit, wherein an input terminal of the voltage detecting circuit is connected with at least two single batteries; a voltage comparator, wherein an input terminal of the voltage comparator is connected with an output terminal of the voltage detecting circuit; a controller connected with the voltage comparator; and discharge circuits connected with all the single batteries. In a battery pack discharge process, the control circuit is capable of ensuring voltage equalization in the battery pack, avoiding inconsistent voltages caused by differences of the single batteries, delaying the situation that the capacity of the battery pack decreases, and prolonging the service lifetime of the battery pack.
