Theoretical performance of a new kind of range extended electric vehicle

Abstract

Typical automotive trips are within the driving range of efficient electric vehicles (EVs), but sometimes exceeding EV range is needed for occasional trips. This paper proposed a new kind of range extended electric vehicle. A mobile generator set is used as a range extender, when assembled in an EV, effectively converts the EV to series-hybrid mode for long trips. The new kind of range extended EV, which integrates the charger, rectifier and DC/DC into a charger, is more suitable for use in low-speed micro EVs than Plugin Electric Vehicle (PHEV) and a Range Extender Trailer (RXT) system. The fuel economy and main performance criteria of the new range extended EV are shown in this paper. In some drive cycles, the new range extended EV has a better fuel economy than PHEV and RXT system. © 2010 WEVA.
