Towing test system for electric drive assembly of new energy vehicle

Introduction:

New energy vehicle electric drive assemblies are increasingly widely used in passenger cars in the automotive industry. The product performance and product quality (motors, controllers, gearboxes) of electric drive assemblies must be ensured during product development and factory inspection. Therefore, it is particularly important to carry out rigorous endurance tests on the performance of the motor. According to the energy efficiency grade and test method of the drive motor system for electric vehicles and the electric drive assembly, and with reference to other national standards and various assembly test standards.
