Schematic diagram of test bench for electric vehicle drive system (EV)

　　500KW electric vehicle drive system test bench test principle diagram as shown above, including battery simulator, motor controller, water cooling system, the tested motor, loading dynamometer, dynamometer test controller, EV powertrain test cabinet (hereinafter referred to as the EV test cabinet), torque sensor, testing, installation and testing of PC platform equipment.

　　This set of low speed and high torque power test platform test system using EV test cabinet, EV cabinet is designed for testing the Milky Way electric electric vehicle powertrain test research of configurable standard measurement and control products, EV test cabinet main test functions, provide quick connector, convenient connection system.

　　The EV test cabinet adopts the virtual instrument architecture, which contains 4 power modules, a 8 channel temperature modules, a torque speed conversion modules, and two data host modules.

　　The 4 power modules can meet the DC input of the motor controller, and the motor controller can be tested in three ways;

　　8 channel temperature module can access 8 PT100 temperature sensor signal;

　　The torque speed converter module can be connected with the torque speed sensor to output two frequency pulse signals.

　　The power module, the temperature module and the torque speed conversion module are used to analyze and process the data, and the test data is shared to the test host computer through the Ethernet LAN port.
