The invention provides a charging control circuit and charging control method of an electric vehicle and a storage medium, and the method comprises the steps: receiving a zero-ground voltage, transmitted by a voltage detection unit, between a zero line and a ground line in a charging process, and judging whether the zero-ground voltage is greater than a preset voltage or not; and when the zero-ground voltage is greater than the preset voltage, controlling a switch unit to be in an off state so as to end charging. In the charging process of the electric vehicle, the zero-ground voltage sent bythe voltage detection unit is received in real time, when the zero-ground voltage is higher than the preset voltage value, it is indicated that the electric leakage risk exists, the switch unit is controlled to be in the off state to quit charging, and therefore the electric leakage risk in the charging process is avoided, and the safety of a user is guaranteed.
本发明提供了一种电动汽车的充电控制电路、充电控制方法和存储介质,在充电过程中,接收电压检测单元发送的零线和地线之间的零地电压,并判断零地电压是否大于预设电压;当零地电压大于预设电压时,控制开关单元处于关断状态,以结束充电。通过在电动汽车充电过程中,实时接收电压检测单元发送的零地电压,当零地电压高于预设电压值时,表明存在漏电风险,则控制开关单元处于关断状态退出充电,从而避免充电过程中漏电风险的发生,进而保障用户的安全。
