Equipped with two high-speed drive ends, each with a maximum speed of 20,000 RPM and a rated torque of 530 Nm, and customizable load motor power. The system includes an environmental chamber, temperature control system, battery simulator, and power analyzer, supporting the development and testing of hybrid transmissions. It also meets the testing needs for electric gearboxes, motors, and powertrains, including fatigue life tests, efficiency tests, high-temperature performance tests, low-temperature start tests, dynamic durability tests, dynamic sealing tests, differential reliability tests, calibration matching tests, mode tests, standard condition tests (NEDC, WLTC, etc.), and custom cycle condition tests.
