The original BYD e5 body and low-voltage control system are selected. The vehicle body is partially cut. The location of the section is reasonable and the internal structure can be clearly displayed. The low-voltage system has complete components, which truly presents the connection and control relationship, installation location and operation parameters of the BYD e5 body low-voltage control system. The system failure analysis and handling ability of the BYD e5 body low-voltage control system are trained. It is suitable for the new energy pure electric course teaching and maintenance training in vocational and technical colleges.

1.All parts of the body low-voltage system are retained, and the electrical connection mode remains unchanged. The students can perform the insertion and disassembly exercise, so that they can master the key points of the body low-voltage system parts in the disassembly and assembly connection process.
2.The training platform can function independently, and the 12V DC power supply is provided by the switching power supply.
3.With the help of courseware data, the functions of main parts and pin definitions are fully described on the display screen of intelligent mobile platform.
4.In addition to the body, the training platform is equipped with a mobile teaching board, which fully displays the working principle diagram of the body low-voltage system, and is equipped with detection terminals. With the help of a multimeter and oscillograph, parameter changes in various states can be detected in real time.
5.The training platform consists of a platform and a teaching board. The platform is placed horizontally and installed with main parts. Four casters are installed at the bottom of the training platform, which can move flexibly. Meanwhile, casters are equipped with self-locking device, which can fix the position.
6.It is equipped with intelligent fault setting and assessment system. The teacher sets the fault, and the student analyzes and finds the fault point. The main parts are drawn out of the test port and directly tested at the fault location to grasp the real vehicle fault handling capacity.
7.The practical training platform is equipped with the practical training instruction, which fully describes the working principle of the practical training platform, training subjects, fault setting and elimination, and other key points.

Whole car body (partial cutting), main controller assembly (main control ECU), gateway controller, body low-voltage control system, and movable teaching board.
