According to the charging starting control circuit, method and device provided by the invention, the first switch module is additionally arranged between the charging pile power supply module and the vehicle charging module, the control end of the first switch module is connected with the charging pile controller, and the virtual voltage caused by safety voltage detection of the charging pile is judged and subjected to simulated discharge; therefore, the conditions that charging starting fails due to the problem of the vehicle safety voltage monitoring circuit, and the vehicle needs to be ignited again, shut down and even inserted and pulled out of a gun are avoided. According to the invention, the type of the voltage is judged through the charging start control circuit, and the corresponding circuit is controlled to operate according to the type of the voltage, so that the success rate of charging start is improved, the problems of charging failure and need of manual plugging and unplugging of a charging gun caused by the problem of a vehicle monitoring circuit are reduced, and the user experience is improved.
本发明提供的一种充电启动的控制电路、方法及装置,在充电桩供电模块和车辆充电模块之间增加第一开关模块,第一开关模块的控制端连接充电桩控制器,对充电桩进行安全电压检测时造成的虚电压进行判别和模拟泄放,从而避免车辆安全电压监测电路问题造成充电启动失败,需要车辆重新打火、熄火甚至插拔枪的情况。本发明通过充电启动控制电路判断电压的类型,根据电压的类型控制对应的电路运行,提高了充电启动的成功率,减少了因车辆监测电路问题造成的充电失败,需要人为插拔充电枪的问题,提升了用户体验感。
