An electric vehicle test bench control system based on single chip computer is designed to test the performance of key parts of electric vehicles such as motors. The system has two circuit boards, namely the main control board and the key board. The main control board has 232 communication circuits, 485 communication circuits, CAN communication circuits, AD acquisition circuits, relay control circuits, data storage circuits, real-time clock circuits, microcontroller and its surrounding circuits. The key board has key input and key indicator control circuits. Rotary encoder is used to adjust the motor′s torque and speed, and Kunlun on-state touch screen is used to set up the parameters of the test bench and observe the operation status. The developed system is tested by experiments. The results show that the system has good operation experience and can meet the needs of electric vehicle component testing.
