【Abstract】 The battery management system is mainly responsible for battery status detection,battery optimization control and battery information processing to ensure the normal operation of the vehicle system. In order to solve the problems of complicated connections,poor system scalability,and high installation and maintenance costs of the current power battery management system,this article uses ternary lithium-ion batteries as the research object and adopts the ZigBee wireless communication method to study and design an efficient and reliable battery management system.The system monitors the operating status of the battery pack in real time,and uses a star-shaped network topology to collect and transmit power battery pack information,thereby realizing information interaction with the vehicle controller and external charging system. After the whole machine test,the results show that the battery management system using Zig Bee can detect various operating parameters with high precision,and has functions such as fault diagnosis,alarm and thermal management,and the system is safe and stable,and meets the requirements of use.更多还原
