基于J1939协议的电池管理系统的设计与实现

Design and realization of battery management system based on J1939 protocal

为了实现电池管理系统信息与汽车其他控制系统信息的共享,设计了基于J1939协议的电池管理系统。该系统以STM32F103系列单片机为主控制器,利用CAN总线与整车进行通讯,CAN通讯协议基于J1939协议制定,监控模块利用电容触摸液晶屏实现,依据管理系统需求设计了液晶屏界面。通过实验测试,该系统可以通过CAN总线进行电池管理系统的功能选择,显示系统参数设置与电池信息,验证了设计协议的合理性和系统的可行性。

In order to share information with other vehicle control systems, a battery management system （BMS） based on J1939 protocol was designed in this paper. In the system, STM32F103 series MCU was adopted as the core controller. CAN bus communication was designed based on J1939 protocol. Meanwhile CAN bus was used to communicate with vehicle bus. Furthermore, a monitoring module was realized with the LCD touch screen and a menu interface on it. In the end, experimental test was done to verify the feasibility and rationality of the designed system. The BMS can use CAN bus to select functions, display system setting parameters and show battery information.
