The invention discloses an equalization circuit, a charging circuit and a vehicle-mounted charger. The equalization circuit comprises an energy storage circuit, N switching circuits and a control circuit, the input ends of the N switching circuits are connected with N battery modules in a one-to-one correspondence manner, and the output ends of the N switching circuits are connected with the energy storage circuit; the control circuit is connected with the controlled ends of the N switching circuits and controls the switching circuits corresponding to the two adjacent battery modules to be alternately turned on so as to control the two adjacent battery modules to alternately charge and discharge the energy storage circuit. Therefore, the voltage balance between the two battery modules is realized, and the voltage balance between the battery modules is realized.

    本发明公开一种均衡电路、充电电路及车载充电机。其中均衡电路包括储能电路、N个开关电路以及控制电路,N个开关电路的输入端与N个电池模块一一对应连接,N个开关电路的输出端均与储能电路连接;控制电路分别与N个开关电路的受控端连接,并控制相邻的两个电池模块对应的开关电路交替开启,以控制相邻的两个电池模块交替对储能电路进行充电和放电;从而实现两个电池模块之间的电压均衡,本发明实现了电池模块之间的电压均衡。
