The invention discloses a charging circuit, a control guide circuit and a charging control method, the charging circuit is applied to a vehicle, and the charging circuit comprises two vehicle end connection confirmation terminals and two divider resistors; the two connection confirmation terminals are respectively and correspondingly connected with one end of the divider resistor, and two voltage detection ports of the vehicle are respectively and correspondingly connected between the corresponding connection confirmation terminals and the divider resistor; the other end of one divider resistor is connected with a first preset power supply of the vehicle, and the other end of the other divider resistor is connected with a vehicle body of the vehicle; when the vehicle is connected with the external power supply equipment, the vehicle controller is configured to switch from the dormant state to the awakening state according to at least one of the voltage signals detected by the two voltage detection ports. According to the charging circuit, the vehicle controller can be automatically switched from the dormant state to the awakening state when the vehicle is charged by inserting a charging gun, the dependence of awakening the vehicle controller on opening and closing of a vehicle key is avoided, and the charging convenience is improved.

    本发明公开了一种充电电路、控制导引电路和充电控制方法,充电电路应用于车辆,充电电路包括:两车辆端连接确认端子、两分压电阻;两连接确认端子分别对应与的分压电阻的一端连接,车辆的两电压检测端口分别对应连接在相应的连接确认端子与分压电阻之间;一个分压电阻的另一端与车辆的第一预设电源连接,另一个分压电阻的另一端与车辆的车身地连接;当车辆与外部供电设备连接时,车辆控制器配置为根据两电压检测端口检测到的电压信号中的至少一者从休眠状态切换至唤醒状态。该充电电路,可实现车辆插充电枪充电时,车辆控制器从休眠状态到唤醒状态的自动转换,避免唤醒车辆控制器对车辆钥匙开闭的依赖,提升充电的便利性。
