The invention provides an electric vehicle wireless charging parking space matching method which comprises the following steps that S1, wireless communication connection is established between vehicle-mounted equipment and ground equipment, and interoperability information detection is completed; s2, the vehicle-mounted equipment of the wireless charging system of the electric vehicle sends a current excitation request message to the ground equipment which completes interoperability information detection, and a rectifying device of the vehicle-mounted equipment is set to be in a short-circuit state; s3, the ground equipment makes a corresponding response through the power control device after receiving the current excitation request message from the vehicle-mounted equipment; s4, a current sensor in the vehicle-mounted equipment transmits a detected induction current signal to a controller, and the controller completes comparison between the content of the current excitation request message and the detected induction current signal; and S5, if the comparison result is consistent, a subsequent process of wireless charging is performed. The matching method provided by the invention can effectively solve the matching problem of the vehicle-mounted equipment and the ground equipment of the wireless charging system of the electric vehicle.
本发明提供了一种电动汽车无线充电车位匹配方法,包括以下步骤:S1、车载设备与地面设备建立无线通信连接,并完成互操作性信息检测;S2、电动汽车无线充电系统的车载设备向已完成互操作性信息检测的地面设备发送电流激励请求报文,并将其整流装置设置为短路状态;S3、地面设备在收到来自车载设备的电流激励请求报文后,通过功率控制装置做出相应的响应;S4、车载设备中的电流传感器将检测到的感应电流信号传递给控制器,由控制器完成电流激励请求报文内容和检测到的感应电流信号的对比;S5、若对比结果相一致,则进行无线充电的后续流程。本发明所述的匹配方法能够有效解决电动汽车无线充电系统车载设备与地面设备的配对问题。
