摘　　要：针对电池管理系统在电动汽车上的应用需求,采用分布式模块多总线结构开发了一种电动车电池监测系统。系统以LPC2368微处理器为核心,硬件上以多总线分别与各个模块进行通信,包括主控单元、强电控制单元和电压采集单元等;软件上分别开发了对应的子程序,并由主控程序统一调度。实验结果表明,该系统监测精度高,数据误差小,各项功能均达到预期效果。Aiming at the application demand of battery management in the electric vehicle（EV）,a kind of EV battery monitoring system based on distributed modules and multi-bus structure was developed.The system adopted LPC2368 MPU as control core,and all modules communicated with multi-bus,including main control component,large voltage control component,voltage sampling component,and so on.In the software system,the corresponding subprogram was designed,and all the subprograms were supervised by the main control program.The test results show that monitor precision is high,data error is little,and all functions meet the expectation.
