一种利用电池单体间分流实现电池组充电的均衡控制电路
摘要：
本申请公开了一种利用电池单体间分流实现电池组充电的均衡控制电路，电池组包括至少两个电池单体，包括：与电源线相连接、且分别与至少两个电池单体相连接的多个充电电路；分别与至少两个电池单体相连接，用于采集至少两个电池单体的电压的电压检测电路；与电压检测电路相连接，用于将至少两个电池单体的电压两两进行比较，并得到比较结果的电压比较器；与电压比较器相连接，用于根据比较结果生成均流信号的控制器；与多个充电电路相连接，且与控制器相连接，用于根据均流信号控制多个充电电路的充电电流大小的均流电路。该控制电路可以降低充电速度较快的电池单体的充电速度，以达到电池组内各节电池单体均衡充电的目的。
