This paper describes research carried out into auxiliary power units (APU) for range extended electric vehicles (RE-EV), as part of the Low Carbon Vehicle Technology Project (LCVTP). APU requirements are specified and compared to the attributes of a variety of prime power sources. It is concluded that for many applications adaption of a volume production 4-stroke gasoline engine will be the most suitable choice for a RE-EV, until production volumes make a bespoke engine viable. The paper explores potential engine modifications and generator integration. The development of a 55kW APU, using a volume production two cylinder engine and a close coupled design permanent magnet generator are described including its installation into a technology validator vehicle.
