One.Summary of National industrial and mining electric drive vehicle quality inspection center transmission system test bench

  The national industrial and mining electric vehicle quality supervision and inspection center was established by the approval of the State Administration of quality inspection, it is currently the only one set of testing and research, standards, information, services, and training as one of the industrial and mining electric vehicle inspection and research institutions. It has independent legal and impartial third party status, will undertake industrial and mining electric drive vehicles, mine transportation and safety equipment and parts of the type test, supervision and inspection, regular inspection, arbitration testing, commissioned the inspection, production license certification and inspection and product development and testing. The transmission system test platform is an important part of the quality inspection center, including an AC motor test bench, a DC motor testing station, mainly used for motor vehicle motor test.
