The embodiment of the invention provides a vehicle wireless charging control method, a vehicle end controller and a wireless charging system. The AC-DC conversion circuit of a vehicle end charging circuit connected with the vehicle end controller is provided with two control switches. The two control switches are respectively connected in parallel with two rectifier diodes connected with the sameoutput end of a vehicle end charging circuit. The control method comprises the following steps: acquiring an actual charging parameter of the vehicle end charging circuit and a preset charging protection parameter of a power battery; comparing the actual charging parameter with a preset charging protection parameter to obtain a comparison result; and when it is determined that charging protectionneeds to be carried out according to the comparison result, the two control switches are controlled to be switched to a closed state. According to the technical scheme, when it is found that chargingprotection needs to be carried out, connection between the power battery and the charging circuit can be rapidly disconnected, damage to the power battery due to voltage and current out-of-control caused by communication delay can be avoided, and the reliability of the whole system is improved.

    本发明的实施例提供了一种车辆无线充电的控制方法、车端控制器即无线充电系统,其中,与车端控制器连接的车端充电电路的AC‑DC变换电路上设置有两个控制开关,两个控制开关分别与连接车端充电电路的同一输出端的两个整流二极管并联,控制方法包括:获取车端充电电路的实际充电参数以及动力电池的预设充电保护参数;将实际充电参数与预设充电保护参数进行比对,得到比对结果;当根据比对结果,确定需要进行充电保护时,控制两个控制开关切换至闭合状态。本发明的技术方案在发现需要进行充电保护时,能迅速断开动力电池与充电电路的连接,有利于避免由于通讯延时导致电压和电流失控对动力电池造成的损伤,提高了整个系统的可靠性。
