SSCH180-4000/15000 New Energy Motor Dynamometer Test Bench

SSCH180-4000/15000 New Energy Motor Dynamometer Test Bench Description

In the field of new energy commercial vehicles and high-end passenger vehicles, 180-kilowatt motors are becoming the mainstream configuration of drive systems. The performance of these high-power motors directly affects the vehicle's range and heavy-load capacity. The 180-kilowatt new energy motor dynamometer test bench is precisely designed as a "performance testing ground" for this type of motor, ensuring stable operation of high-power motors in complex application scenarios through full-condition simulation and precise data collection.

The dynamometer test bench is designed with a core power range of 180 kilowatts, which can simulate extreme conditions such as commercial vehicle climbing (slope ≥30%) and passenger vehicle high-speed cruising (speed > 160km/h), and also has the ability to test bidirectional energy flow. When the motor is in the power generation state (such as when the vehicle brakes downhill), the test bench can feed the regenerated electricity back to the grid with an energy recovery rate of over 95%, reducing the energy consumption cost of the test and realistically recreating the vehicle energy management scenario.
