A charging control circuit and an electronic device belong to the technical field of electric vehicles, and detect the short circuit state of a charging cable through a detection circuit to output a detection voltage; the comparison circuit compares the detection voltage with the reference voltage and outputs a control signal according to a comparison result; the driving circuit outputs a driving signal according to the control signal; the switching circuit disconnects the charging cable from the power grid according to the driving signal. Therefore, when the charging cable is short-circuited, the switching circuit can disconnect the charging cable and the power grid in time, the short-circuit fault is quickly eliminated, the fire of the charging pile is avoided, and the safety of the circuit is improved.
一种充电控制电路及电子设备,属于电动汽车技术领域,通过检测电路对充电线缆的短路状态进行检测,以输出检测电压;比较电路将检测电压与参考电压进行比较,并根据比较结果输出控制信号;驱动电路根据控制信号输出驱动信号;开关电路根据驱动信号断开充电线缆和电网的连接。从而实现了充电线缆短路时,开关电路能够及时断开充电线缆和电网的连接,快速排除短路故障,避免充电桩起火,提升了电路的安全性。
