The invention belongs to the technical field of wireless charging of new energy vehicles, and particularly discloses a control method of a wireless charging contactor, which is characterized in that a vehicle node exchanges information in a CAN communication mode, and a vehicle control unit VCU is used as an information interaction hub and a control dispatching center to achieve automatic control of a wireless charging full cycle. The wireless charging contactor can be automatically controlled in the wireless charging process, manual participation is not needed, and safety risks caused by the fact that a user directly makes contact with a charging medium are avoided; the control instruction of the wireless charging contactor is reliable, flexible and safe, only two control instructions exist in one charging period, the frequent action of the wireless charging controller among multiple charging cycles in one charging period is effectively avoided, the disconnection instruction is sent only when the wireless charging current is within the safe range, and the wireless charging contactor is safe. Therefore, the service life of hardware of the wireless charging contactor is prolonged, and the maintenance cost is reduced.
本发明属于新能源汽车无线充电技术领域,具体公开了一种无线充电接触器的控制方法,整车节点通过CAN通讯方式进行信息交换,以整车控制器VCU为信息交互枢纽和控制调度中心,以达到对无线充电全周期的自动控制。本发明使无线充电过程可满足对无线充电接触器的自动控制,无需人工参与,没有用户直接接触充电媒介带来的安全风险;本发明对无线充电接触器的控制指令可靠、灵活、安全,一个充电周期内仅有两次控制指令,有效的避免了一个充电周期内多次充电循环间无线充电控制器的频繁动作,仅在无线充电充电电流在安全范围内发出断开指令,杜绝带电断开的动作,提高了无线充电接触器硬件使用寿命、降低维护成本。
