The effect of PHEV battery range distributions on competitiveness: Implications for design strategy and energy-efficiency policy

TL;DRAbstract

Electric vehicles have the potential to contribute to increased energy efficiency. However, competition is fierce among designs, energy carriers, and powertrains; electric vehicles must be economically viable from a consumer point of view. Batteries are still expensive; short of a breakthrough, the energy battery will constitute a considerable share of the vehicle cost for the foreseeable future. Economically efficient battery use is therefore very important. Plug-in hybrid electric vehicles (PHEV) constitute a response to this efficiency requirement. PHEVs rely on a relatively small battery, while still allowing a considerable share of the driving to be powered by electricity. In previous studies, we investigated optimal battery sizes, from the individual consumer’s perspective. In reality, only a limited number of battery sizes will be available. Understanding the relationship between a limited choice of battery sizes and the potential for PHEVs should be of value to car manufacturer
