Rationale: Power ratings provided for ICE vehicles are obtained from component-level tests of the engine power output (SAE J1349). However, electrified powertrains often consist of multiple power-producing components that may include an engine and one or more electric motors. These components are coupled in a wide variety of configurations and can operate as a system to produce propulsion power in ways that are not predictable a priori. As a result, a new power test procedure is needed for all types of electrically propelled vehicles to measure and report powertrain power as a full system. This powertrain-level testing approach addresses the challenge of providing fair and unbiased comparisons among all vehicle powertrain designs.
