The invention discloses an electric vehicle charging wake-up circuit which comprises a CP signal driving circuit and an enabling control circuit, the input end of the CP signal driving circuit inputs a CP signal, the output end of the CP signal driving circuit is connected with the enabling control circuit, one end of the enabling control circuit is connected with KL30, and the other end of the enabling control circuit is connected to the enabling input end of a power management chip; and the CP signal driving circuit is used for outputting and controlling the enable control circuit to output a wake-up signal to the enable input end of the power management chip based on the CP signal. The circuit has the advantages that the circuit structure is simple, stable and reliable; the CP signal is adopted to perform wake-up control, and the CP signal is used as a wake-up signal source, so that even if the charging gun is in an inserted state after charging is completed, the equipment can normally enter a dormant state, the consumption of the storage battery is reduced, and the risk of feed of the storage battery is solved. The anti-interference capability of the circuit is high; the circuit response is fast; the circuit is simple and cost-saving.

    本发明公开了一种电动汽车充电唤醒电路,包括CP信号驱动电路、使能控制电路,CP信号驱动电路的输入端输入CP信号,其输出端连接使能控制电路,所述使能控制电路的一端连接KL30,另一端连接至电源管理芯片的使能输入端;所述CP信号驱动电路用于基于CP信号来输出控制使能控制电路输出唤醒信号至电源管理芯片的使能输入端。本发明的优点在于:电路结构简单且稳定可靠;采用CP信号进行唤醒控制,使用CP信号作为唤醒信号源,即使充电完成后,充电枪处于插枪的状态,设备可以正常进入休眠状态,减少蓄电池消耗,解决蓄电池馈电的风险。电路抗干扰能力强;电路响应快;电路简单、节约成本。
