A charging circuit and a charging pile belong to the technical field of charging, a sensing circuit outputs a sensing signal when sensing a device to be charged, and stops outputting the sensing signal when not sensing the device to be charged; the control circuit outputs a control signal when receiving the induction signal, and stops outputting the control signal when not receiving the induction signal; the switching circuit accesses charging voltage, is switched on when receiving the control signal so as to output the charging voltage to the to-be-charged equipment, and is switched off when not receiving the control signal so as to stop outputting the charging voltage to the to-be-charged equipment; wherein the induction signal and the control signal are level signals; therefore, when the to-be-charged equipment is not charged, the output of the charging voltage is safely and reliably stopped, the electric shock danger caused by electrification of the charging electrode connected with the switching circuit is effectively avoided, and the safety of the charging circuit is improved.
一种充电电路及充电桩,属于充电技术领域,通过传感电路当感应到待充电设备时输出感应信号,当未感应到待充电设备时,停止输出感应信号;控制电路当接收到感应信号时输出控制信号,当未接收到感应信号时停止输出控制信号;开关电路接入充电电压,在接收到控制信号时接通,以输出充电电压至待充电设备,在未接收到控制信号时关断,以停止输出充电电压至待充电设备;其中,感应信号和控制信号均为电平信号;从而在待充电设备未充电时安全可靠地停止输出充电电压,故有效避免了与开关电路相连的充电电极带电而造成触电危险,提高了充电电路的安全性。
