SSCH60-4000/15000 650Nm 0.2%FS New Energy Motor Electric Dynamometer Test Bench

SSCH60-4000/15000 New Energy Motor Electric Dynamometer Test Bench

SSCH60-4000/15000 New Energy Motor Electric Dynamometer Test Bench Description

Under the trend of miniaturization and lightweighting of new energy vehicles, 60-kilowatt motors have become the core power source for urban logistics vehicles and small passenger cars. The 60-kilowatt new energy motor electric dynamometer test bench, providing all-round performance verification for motor research and development and production through precise working condition simulation and efficient data collection. ​

The new energy motor test bench is designed with a power of 60 kilowatts as its core. It can simulate typical conditions such as urban road congestion start-stop and suburban road cruise, and supports motor-electric/power generation bidirectional mode tests. When the motor is in an energy recovery state (such as downhill braking), the test bench can feed more than 85% of the regenerative power back to the grid, reducing the test's energy consumption and realistically recreating the vehicle's energy management scenario. ​
