摘　　要：为了将车载端与地面端充电设施统一起来,实现不同电动汽车与不同地面端充电桩之间高效、安全地进行无线充电,保证无线通信协议的一致性至关重要。本文首先对新颁布的电动汽车无线充电系统通信协议标准GB/T 38775.2-2020进行解读,梳理得到电动汽车无线充电通信的一般流程;然后,设计了一种电动汽车无线充电通信一致性测试的软硬件架构;最后,提出了电动汽车无线充电通信协议的一致性测试方法。该系统能够完成电动汽车无线充电过程中通信协议的自动化测试,有助于后续标准的修订和测试的进一步完善。In order to unify the charging facilities of vehicle assembly(VA)and ground assembly(GA),and realize efficient and secure wireless charging between different VAs and GAs,it is very important to ensure the conformance of wireless communication protocols.Firstly,this paper interprets the newly issued communication protocol standard GB/T 38775.2-2020 for electric vehicle(EV)wireless charging system,and summarizes the general process of EV wireless charging communication.Then,a software and hardware architecture for conformance test of wireless charging communication for EVs is designed.Finally,the test method of electric vehicle charging protocol is proposed.The system can complete the automatic test of communication protocol in the process of EV wireless charging,which is helpful to the revision of subsequent standards and the improvement of further test.
