Design and Development of the Range Extender Engine
Published May 23, 2012 by Society of Automotive Engineers of Japan in Japan
Pure electric vehicles require bulky, heavy and expensive battery packs to enable an acceptable drivable range to be achieved. Extended-range electric vehicles (E-REV) partly overcome the limitations of current battery technologies by having a "range extender" unit, which consists of an onboard fuel converter that converts a liquid fuel, such as gasoline, into electrical energy whilst the vehicle is driving. This paper presents an overview of the design and development of an engine specifically for the use as a range extender.
