一种电池组充电均衡控制电路
摘要：
本申请公开了一种电池组充电均衡控制电路，电池组包括至少两个电池单体，该均衡控制电路包括：与电源线相连接、且分别与至少两个电池单体相连接的充电电路；分别与至少两个电池单体相连接的电压检测电路；与电压检测电路相连接的电压比较器；与电压比较器相连接，且与充电电路相连接的控制器；与多个充电电路相连接，且与控制器相连接的均流电路。该电路不仅为充电电路设定了不同的充电模式或充电档位，并根据电池组内电池单体之间的电压对充电情况进行控制，实现电池单体之间更加均衡，而且还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。
摘要（英）：

The application discloses a charging balancing control circuit for a battery pack, and the battery pack comprises at least two cells. The balancing control circuit comprises charging circuits connected with a power line and respectively connected with the at least two cells; a voltage detection circuit connected with the at least two cells; a voltage comparator connected with the voltage detection circuit; a controller connected with the voltage comparator and the charging circuits; and a current sharing circuit connected with the plurality of charging circuits and the controller. The battery pack charging balancing control circuit is advantageous in that different charging modes or charging shifts are set to the charging circuits, and charging conditions are controlled according to the voltages between the cells in the battery pack to make the cells more balanced; and the charging speed of the cell whose charging speed is high can be reduced, so that the charging of the cells in the battery pack is balanced.
