The invention discloses an overcharge protection circuit and an electric vehicle, and the overcharge protection circuit comprises a discharge loop which comprises a battery, a first switch and a resistor; the control unit is connected with the battery and the first switch, and the control unit is configured to control the first switch to be switched on and switched off periodically when the electric quantity of the battery is larger than a set proportion threshold value so as to discharge the battery through the discharge loop, and control the first switch to be switched off when the electric quantity of the battery is smaller than the set proportion threshold value. In this way, battery damage caused by overcharge of the battery can be avoided.

    本申请公开了一种过充保护电路以及电动汽车,该过充保护电路包括:放电回路,放电回路包括电池、第一开关和电阻;控制单元,控制单元连接电池和第一开关,控制单元被配置为在电池的电量大于设定比例阈值时,控制第一开关周期性地导通和断开,以利用放电回路对电池进行放电,以及在电池的电量小于设定比例阈值时,控制第一开关断开。通过上述方式,可以避免电池过充导致电池损坏。
