Results of the ETV-1 breadboard tests under steady-state and transient conditions
Test results are presented of a breadboard version of the ETV-1 electric vehicle propulsion system built by General Electric Company under contract to NASA-LeRC as a part of the Department of Energy (DOE) Electric and Hybrid Vehicle Program. The breadboard was installed in the NASA-LeRC Road Load Simulator facility and tested under steady state and transient conditions. Steady state tests were run to characterize the system and component efficiencies over the complete speed-torque capabilities of the propulsion system in both motoring and regenerative modes of operation. The steady state data were obtained using a battery simulator to separate the effects on efficiency caused by changing battery state-of-charge and component temperature. Transient tests were performed to determine the energy profiles of the propulsion system operating over the SAE J227 a driving schedules.
