Method and system for dynamometer testing of electric vehicles

摘要

The present invention relates to a method for use in dynamometer testing of a vehicle powertrain component or a vehicle (100), a dynamometer power source (201) of a vehicle dynamometer system being connected to an output shaft of a vehicle powertrain component or a vehicle wheel shaft, said dynamometer system being arranged to measure a reaction load and said method including, when testing: determining a first measure of a first reaction load of said first dynamometer power source, determining an influence of moment of inertia on said first measure of said first reaction load, and compensating said first measure of said first reaction load by said determined influence of moment of inertia.
