摘　　要：提出了一种基于STM32F407和BQ76PL536芯片的电池管理系统设计方案,实现了电池组中各个单体电池温度和电池电压的实时监测,以及在此基础上实现了以电池电压为均衡判据的充放电均衡处理策略,避免了电池充放电过程中的过温、过充、过放和充放电不均衡等现象,从而实现了延长电池使用寿命的目标。该方案设计有CAN总线接口,实现了电池管理主控板与其他设备的可靠通信,为电池管理系统的功能扩展提供了方便。A design of battery management system based on STM32F407 and BQ76PL536 chip was presented. The real-time monitoring of the battery temperature and battery voltage of each cell in the battery pack was realized, and the charge and discharge equalization strategy based on the battery voltage was achieved. The phenomenon of over-temperature, over-charge and over-discharge in the process of charging and discharging of the battery were avoided, thereby achieving the purpose of prolonging the service life of the battery. The scheme was designed with CAN bus interface, which realized the reliable communication between the main board and other equipment. The scheme provides convenience for the function expansion of the battery management system.
