电动汽车大功率充电技术现状分析

Analysis on High Power Charging Technology of Electric Vehicles

随着电动汽车续航里程的增加,为有效解决2015版充电连接组件的缺陷,满足广大电动汽车用户的需求,完善大功率充电技术迫在眉睫。为此中电联大功率充电技术工作组设计了全新的HPC充电连接组件、全新的HPC控制导引电路、全新的HPC转换器,还针对性地启动编写全新的HPC通信协议。工作组吸取上一代充电技术升级换代的经验教训,将大功率充电技术的关注点聚焦在安全性、可靠性和兼容性,保证大功率充电连接组件标准与2015版充电连接组件标准的协调,满足新桩与旧车的兼容以及旧桩与新车的兼容。在中日HPC方案基础上,下一步中国将和日本联合递交HPC安全IEC标准提案,与欧盟和美国的特斯拉体系进行协同。

With the increase of electric vehicles’range,it is urgent to improve high power charging technology to effectively solve the defects of charging connection components of the 2015 version and meet the needs of the majority of electric vehicle users.For this reason,the high power charging technology working group of CLP designed a new HPC charging connection module,a new HPC control guidance circuit,a new HPC converter,and also started to write a new HPC communication protocol.Drawing lessons from the upgrading of the last generation of charging technology,the working group focused on safety,reliability and compatibility of the high power charging technology,ensuring the coordination between the high power charging connection module standard and the 2015 version of the charging connection module standard,to meet the compatibility between the new pile to old vehicle,and old pile to new vehicle.Based on the China-Japan HPC plan,the next step for China and Japan is to jointly submit the HPC safety IEC standard proposal,which will be coordinated with the Tesla system in the European Union and the United States.
