摘 要：電动汽车电池系统由动力电池组和电池管理系统组成。为了更好指导整车电池系统的开发，现以一组动力电池为控制对象，基于STM32芯片设计设计一个电池管理系统。设计过程中根据电池特性和供电需求确定电池管理系统的拓扑结构，通过划分功能模块进行硬件模块电路设计和软件开发，制作一个电池管理系统。实验证明设计的电池管理系统能够对电池组进行信息采集和处理，通过显示屏反馈数据，并对电池组进行保护，对整车的电池管理系统设计起指导作用。

Abstract：Electric vehicle battery system consists of power battery pack and battery management system. To better guide the development of the vehicle battery system， a battery management system is designed based on the STM32 chip with a group of power batteries as the control object. The topology of the battery management system is determined by the battery characteristics and power supply requirements in the design process. The hardware module circuit design and software development are carried out by dividing the functional modules to make a battery management system. The experiment proves that the designed battery management system can collect and manage the information of the battery pack， feedback the data through the display screen， and protect the battery pack， which plays a guiding role in the design of the battery management system of the whole vehicle.
