The invention provides a control method of a vehicle charging system, the vehicle charging system, a vehicle and a medium, and the control method of a charging liquid cooling system comprises the steps: obtaining a prediction parameter in response to the start of charging of the vehicle and the reception of a fault signal; inputting the prediction parameter and a first condition into a prediction model to obtain a first prediction temperature of the charging wire harness, wherein the first condition comprises that the heat dissipation part is in a closed state; when the first prediction temperature is larger than or equal to a first threshold value and at most one of the coolant pump and the fan is in a fault state, the prediction parameters and a second condition are input into the prediction model to obtain a second prediction temperature of the charging wire harness, and the second condition includes that the heat dissipation component is in an operation state; when the second predicted temperature is larger than or equal to a second threshold value, the current charging current is reduced, and the second predicted temperature is obtained again until the second predicted temperature is smaller than the second threshold value; when the liquid cooling system breaks down, the charging requirement of a user can be met as much as possible, and it is guaranteed that the working temperature of the charging wire harness is low.
本发明提供一种车辆充电系统的控制方法、车辆充电系统、车辆及介质,其中,充电液冷系统的控制方法包括:响应于车辆开始充电且接收到故障信号,获取预测参数;将预测参数和第一条件输入预测模型得到充电线束的第一预测温度,第一条件包括散热部件处于关闭状态;当第一预测温度大于或等于第一阈值且冷却液泵和风机至多一个处于故障状态,将预测参数和第二条件输入预测模型得到充电线束的第二预测温度,第二条件包括散热部件处于运行状态;当第二预测温度大于或等于第二阈值,减小当前充电电流并重新获取第二预测温度,直至第二预测温度小于第二阈值;在液冷系统发生故障的情况可以尽量满足用户的充电需求,并保证充电线束的工作温度较低。
