CAN总线在电动汽车BMS系统与充电桩之间通信的应用

The Application of CAN bus for communications between the Electric vehicle's BMS manage system and charge picket

电动汽车是我国新能源战略重点之一,国家电网公司为此积极展开电动汽车充电站的建设。国家电网将按照换电为主、插充为辅,集中充电、统一配送为基本商业模式,加快电动汽车充换电站的布局和建设。不论是插充方式还是集中充电,电动汽车的普及都离不开充电智能化,而BMS与充电桩或其他充电设备的无缝连接正是实现充电智能化的必要条件。文章提出了BMS管理系统与充电桩之间的通信设计方案,利用CANBUS实现BMS管理系统与充电桩的通讯,介绍了CAN通讯的硬件设计和软件设计,并经过与充电桩的反复测试,实现了BMS管理系统与充电桩的通信。

Electric vehicle is one of our China strategy focus,the State Grid Corporation launched this active constrction of electric vehicle charging station.State Grid will follow the main plug charging,giving the concentration of charge,the uniform distribution as the basic business model for electric vehicle charging station to speed up the layout and construction.Way or whether it is insertet fully concentrated charge,without charging intelligent,the popularity of electric vehicles will not be implemented,and BMS and charging pile,or other charging device to achieve seamless connectivity is a necessary condition for charging intelligent.In this paper,a design scheme of communication between BMS and charging pile is proposed.BMS using CANBUS achieve the communication with the charging pile.Introduced CAN communications hardware and software design.After repeated testing,the communication between BMS and charging pile was implemented.
