Abstract

The invention discloses a test system and a test bench for electric vehicle driving modules and belongs to the field of vehicles. The test system comprises a control module, a first driving module, a torque sensor, a data acquisition module and a power source. The control module is connected with the first driving module and the data acquisition module respectively through a controller area network (CAN) bus, the torque sensor is connected with the first driving module and the data acquisition module respectively, and the first driving module is connected with the power source. The test system comprising the long-lasting power source, the driving module and the control module is used for endurance tests of electric vehicle driving modules, defects that test is in failure due to low battery power and people need to charge batteries repeatedly when the driving modules mounted on the electric vehicles are tested on real road surfaces are overcome, test cycle of the driving modules is shortened, and test efficiency is improved.
