Driving Schedules Influence Electric and Hybrid Vehicle Efficiency 1999-01-2707
The specific mission was to determine the effect of driving schedules on the efficiency of battery powered electric vehicles (EV) and hybrid engine/electric vehicles (HEV). Efficiency was referenced to the hydrocarbon (HC) fuel source which provided the electrical energy. In the case of the battery powered pure electric vehicle, the HC source was referenced to the public utility HC fuels. While, in the case of hybrid electric vehicles, the HC source was carried on board the HEV in the vehicle fuel tank.
