Hybrid Vehicle Comparison Testing Using Ultracapacitor vs. Battery Energy Storage

With support from General Motors, NREL researchers converted and tested a hybrid electric vehicle (HEV) with three energy storage configurations: a nickel metal-hydride battery and two ultracapacitor (Ucap) modules. They found that the HEV equipped with one Ucap module performed as well as or better than the HEV with a stock NiMH battery configuration. Thus, Ucaps could increase the market penetration and fuel savings of HEVs.
