摘要: 国内电动汽车的充电协议与欧盟等国电动汽车协议不同,必须安装符合欧盟标准的充电通信控制器才能出口到欧盟市场。国内电动汽车制造商若单独开发欧标协议为基础的产品,需改变现有电池管理系统(BMS)和充电控制器,协议一致性和互操作性难以短期提升,需不断完善验证和优化,研发时间成本巨大。鉴于此,选用国产MCU和PLC芯片设计了基于ISO15118的电动汽车充电通信控制系统,它和国产电动汽车采用GB/T 27930协议进行CAN通信就可转换为满足欧标ISO15118协议和DIN70121协议的PLC通信。实际应用表明,该系统支持即插即充功能,满足ISO15118协议通信安全机制,兼容性好、互操作性强、成本低,使用方便。

Abstract: The charging protocol for domestic electric vehicles is different from that of the European Union and other countries, and a charging communication controller that meets EU standards must be installed before it can be exported to the EU market. If domestic electric vehicle manufacturers independently develop products based on the European standard protocol, they need to change the existing battery management system (BMS) and charging controller. The consistency and interoperability of the protocol are difficult to improve in the short term, and continuous improvement, verification, and optimization are required, resulting in huge research and development time costs. In view of this, domestic MCU and PLC chip were selected to design an electric vehicle communication control system based on ISO15118. It can be converted into PLC communication that meets the European standard ISO15118 protocol and DIN70121 protocol by using GB/T 27930 protocol for CAN communication with domestic electric vehicles. Practical application shows that the system supports PnC, meets the communication security mechanism of ISO15118 protocol, has good compatibility, strong interoperability, low cost, and is convenient and flexible to use.

引言

随着全球低碳转型和碳达峰、碳中和目标的不断推进,新能源汽车作为新兴产业的重要代表,正以前所未有的速度发展。中国作为全球新能源汽车产业的领头羊,不仅在国内市场取得了显著成就,也在逐步进军海外市场。我国电动汽车出口面临的主要问题是,国内电动汽车的充电协议与欧盟等国电动汽车协议不同,必须安装符合欧盟标准的充电通信控制器才能出口到欧盟市场。国内电动汽车制造商若单独开发欧标协议为基础的产品,需改变现有电池管理系统(BMS)和充电控制器[1-2],协议一致性和互操作性难以短期提升,需不断完善验证和优化,研发时间成本巨大。若采用国外充电通信控制器,则面临价格高、技术支持困难等问题。鉴于此,选用国产MCU控制器[3-4]和PLC芯片设计了基于ISO15118的电动汽车通信控制系统[5-8],它和国产电动汽车BMS采用GB/T 27930协议进行CAN通信就可转换为满足欧标ISO15118协议和DIN70121协议的PLC通信,且协议一致性好、互操作性强,支持即插即充PnC功能,还满足了ISO15118的通信安全机制,从而解决了我国电动汽车出口的诸多问题。
