This surge has spurred the expansion of the electric vehicle (EV) market, specifically battery electric vehicles (BEVs), stimulated by rising fuel prices and commitments to offer an environmentally friendly alternative to conventional combustion engines.
Some analysts have concluded that fuel cell electric vehicles are less efficient than battery electric vehicles since the fuel cell system efficiency over a driving cycle might be only 52%, whereas the round trip efficiency of a battery might be 80%. However, this neglects the effects of extra vehicle weight on fuel economy.
These curves demonstrate that all battery technologies involve a trade off between energy and power. For hybrid vehicles power is the major driver, since the onboard fuel provides stored energy via the internal combustion engine. An all electric vehicle requires much more energy storage, which involves sacrificing specific power.
Battery electric vehicles are vehicles that run entirely on electricity stored in rechargeable batteries and do not have a gasoline engine, thereby producing zero tailpipe emissions.
The adoption of EVs presents an opportunity for demand response and smart grid technologies to manage and optimize energy supply. Emerging experimental research highlights the potential of using electric vehicles as dispersed energy resources that can store and feed energy back into the grid during peak-demand periods [, , , ].
