A method for testing power of an electric drive system includes setting the electric motor of the electric drive system to a desired speed and applying a brake load to the system. The method also includes increasing the brake load until an engine of the electric drive system is fully loaded. After the engine is fully loaded, the method includes maintaining the brake load until the acceleration remains between the upper predetermined threshold and the lower predetermined threshold for the predetermined period of time, which indicates that the engine has stabilized at full power. Once the engine is at full power, the commanded power of the electric drive system required for stabilizing the engine at full power is averaged, and the average power is compared to a predetermined pass/fail threshold to determine if the electric drive system has sufficient power.
