针对欧盟AFIR法规推进下欧洲充电桩异构性加剧的车桩兼容性风险,文章提出基于充电特性分析的欧标兼容性测试方法。通过剖析DIN 70121、ISO 15118等标准下充电桩的通信协议、电气参数、保护策略差异,搭建涵盖充电性能、可靠性、边界值、适配性、故障注入的虚拟测试台架,模拟硬件与协议异常场景。通过该方法可以模拟欧标充电失败场景,降低海外实桩测试成本,为电动汽车出口欧洲的车桩协同优化提供技术支撑。

In response to the increased heterogeneity of European charging piles under the promotion of the EU AFIR regulation, which has led to the risk of vehicle and pile compatibility, this article proposes a European standard compatibility testing method based on the analysis of charging characteristics. By analyzing the differences in communication protocols, electrical parameters and protection strategies of charging piles under standards such as DIN 70121 and ISO 15118, a virtual test bench covering charging performance, reliability, boundary values, adaptability and fault injection was built to simulate abnormal scenarios of hardware and protocols. This method can simulate the failure scenarios of European standard charging, reduce the cost of overseas real-pile testing, and provide technical support for the coordinated optimization of vehicles and charging piles when electric vehicles are exported to Europe.
