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.
