The invention discloses a battery equalization circuit and an electric vehicle. The battery equalization circuit comprises a battery pack which comprises n single batteries which are sequentially connected in series; the first end of the voltage balancing module is electrically connected with the positive end of the battery pack, and the second end is electrically connected with the negative end of the battery pack; the plurality of switch groups are arranged in one-to-one correspondence with the battery monomers; the switch group comprises a first switch and a second switch, the first switch is connected in series between the positive electrode of the corresponding single battery and the first end of the voltage balancing module, and the second switch is connected in series between the negative electrode of the corresponding single battery and the second end of the voltage balancing module. The voltage of each single battery does not need to be detected, a detection module does not need to be configured, the cost is reduced, the control module directly outputs a control signal to control the first switch and the second switch to be switched on and switched off, voltage balance of the single batteries is achieved, and the control process is simpler and more efficient.

    本发明公开了一种电池均衡电路及电动汽车。电池均衡电路包括:电池组,电池组包括n个依次串联连接的电池单体;电压均衡模块,电压均衡模块的第一端与电池组的正极端电连接,第二端与电池组的负极端电连接;多个与电池单体一一对应设置的开关组;开关组包括第一开关和第二开关,第一开关串联连接于对应的电池单体的正极和电压均衡模块的第一端之间,第二开关串联连接于对应的电池单体的负极和电压均衡模块的第二端之间。无需对每一电池单体的电压进行检测,无需配置检测模块,成本降低,控制模块直接输出控制信号控制第一开关和第二开关导通和关断,实现电池单体的电压均衡,控制过程更为简单、高效。
