The AC (alternating current) electric dynamometer test bench consists of an AC electric dynamometer, a traction motor, a frequency converter ACS800, a motor controller, a power analyzer WT3000 and others. By simulation of ADVISOR (Matlab/Simulink based simulation software), relationship between traction motor speed n and load torque Tz in ECE-EUDC (Economic Commission of Europe - Extra Urban Driving Cycle) driving cycle was obtained, which was synchronously transmitted to the motor controller and the dynamometer converter by the CAN (controller area network) interface card. Experiment shows the real driving cycle state can be simulated on the AC electric dynamometer test bench. Result of energy consumption economy by ADVISOR and test bench is basically consistent, which is of great significance on EV (electric vehicle) development research.
