9. The battery management system on the teaching board can detect signals including power supply, interlock signal, CAN signal, etc.

10. The smart key system on the teaching board can detect signals including high-frequency receiver signals, RF card reader signals, antenna receiver signals, etc.

11. The air conditioning control unit on the teaching board can detect signals including cooling and heating regulating motor signal, internal and external circulation motor signal, air outlet mode circulating motor signal, air conditioning pressure switch signal, evaporator temperature sensor signal, outdoor temperature sensor signal, indoor temperature sensor signal, sun sensor signal, electronic expansion valve signal, defrost mode motor signal, etc.

12 The electric steering system on the teaching board can detect signals including power supply, CAN signal, etc.

13. The AC charging port unit teaching and training system can detect signals including unlocking power supply, blocking power supply, high temperature sensor, low temperature sensor, CC signal, CP signal, etc, and it can set and diagnose faults such as open circuit, virtual connection and short circuit of the main circuit of the AC charging port unit.

14. Equipped with an intelligent fault setting and assessment system. Through waifa wireless fault setting, the teacher sets the fault, and the students analyze and find the fault point to master the fault handling ability of the real vehicle. And the equipment has wireless fault set at least 30 points.

15. The detection board is made of advanced aluminum-plastic plate with characteristics of not less than 4mm thick, corrosion resistance, impact resistance, pollution resistance, fireproof, and moistureproof. Its surface are processed by special craft and spraying primer. The board is printed with a never fade color control unit plug and socket terminal diagram, and install 2mm gold-plated detection terminals. Trainees can measure and analyze the working principle and signal transmission process of each control system by comparing the original car circuit diagram and the original car.
