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.
