Analysis of DC Charging Interoperability for EV and Design of Testing Program

针对车辆与非车载充电机在充电时的常见问题,设计一套试验室测试方案与现场测试方案,分析影响充电兼容性的主要原因,并进行系统总结,旨在为电动汽车与非车载充电机的充电互联互通提供技术支撑,促进新能源汽车的健康有序发展。结果表明,目前影响充电互联互通的主要原因为报文、时序、功能以及其他问题等。文章最后对提高充电兼容性提出了一些建议。

The interconnection between electric vehicles and off-board conductive chargers is an important factor in ensuring the development of new energy vehicles. Focusing on common problems of vehicles and off-board conductive chargers during charging, this article designs a set of laboratory test programs and field test programs, analyzes the main reasons that affect the compatibility of charging, and carries out a systematic summary, aiming at the electric cars and off-board conductive chargers which can provides technical support for the charging and interconnection of on-board chargers and promotes the healthy and orderly development of new energy vehicles. The results divide the main reason affecting charging interconnection and interoperability into four aspects： packet, timing, function, and other issues. At the end of the article, some suggestions on improving charging compatibility are provided.
