Abstract: In order to solve the problem of offline performance testing of the charging system in the teaching of electric vehicle courses, design a controller area network (CAN) bus controlled charging system teaching platform. The article elaborates on the platform design from the composition of the charging system, working principle, platform architecture, hardware selection, software design, and test. Use the USB-CAN interface card to connect the PC as the upper computer to the charging system. Send CAN messages to control the operation of the charging system. Record the output voltage and current values of the 60 s loading test to determine the performance of the charging system. Carry out teaching through the teaching platform, students can master the knowledge and skills of CAN bus control principle of charging system, drive control, and charging machine testing, Provide visual learning scenarios for course instruction, job requirements for the integration of new technologies in electric vehicle repair, enhancing the effectiveness of practical training.
