Method and system for dynamometer testing of electric vehicles

摘要

The present invention relates to a method for dynamometer testing of a vehicle powertrain component or vehicle (100), wherein a dynamometer power source (201) of the vehicle dynamometer system is connected to an output shaft of the vehicle powertrain component or a vehicle axle. The dynamometer system is configured to measure the reaction load, and the method determines, during the test, a first measurement of the first reaction load of the first dynamometer power source; Determining the effect of the moment of inertia on the first measured value of the first reaction load, and correcting the first measured value of the first reaction load with the determined effect of the moment of inertia. .
