【Features】

●Our Laboratory has experience in the development of EV drive-motors and powertrain test/sample tests based on legal requirements/simulation test to operating conditions and energy consumption of finished products.

●Our Laboratory has experience in the development of whole-vehicle energy flow test for EVs, which can assist the customers in quality verification of motors and powertrain.

●Our Laboratory adopts the AVL dynamometer system of the same level as major international vehicle manufacturers, which can provide a measurement of data with high precision and stability and multiple editing modes to reflect as much as possible the actual operating conditions when driving a vehicle. The test results could be used to forecast product problems in advance so that the countermeasures could be improved and confirmed prior to mass production.
