基于CAN总线的电池充放电管理系统的研究
Study on the Battery Management System Based on CAN Bus
According to the distribution curve of the battery charging process,the paper describes the main battery charging circuit topology and the corresponding control strategy in detail,focusing on the DC / DC converter control method of distributed charge balance.The overall structure map of the battery charging circuit was designed,and the balanced grading system for the BUCK-BOOST topology was analyzed.The paper finally analyzed the CAN bus communication control battery,designed the distributed battery management system.In order to achieve single cell parameters(voltage,current and temperature) accurate collection,it designed the circuit and main circuit topology based on the MCU CAN-bus real-time transmission.Through the CAN bus to communicate with the central processor,the battery is made truly real-time management.The battery charge and discharge management system will play a guiding role in thebattery life and efficient management.
