To achieve acceptable range and dynamic performance, pure electric vehicles require batteries which are expensive, heavy and bulky. One feasible solution to overcome the limitations in current battery technology is the integration of an on-board 'fuel converter'. Its function is to convert liquid fuel, such as gasoline, into electrical energy whilst driving, thus enabling the traction battery storage capacity to be reduced, whilst still maintaining an acceptable vehicle range. Based on this primary function, the on-board fuel converter has become known as a range extender.
In simple terms, the range extender is an auxiliary power unit consisting of a small internal combustion engine coupled with an electric generator which is used to re-charge the battery pack.
MAHLE Powertrain recognised the potential benefits in the application of range extenders and set out to design and develop its own unit in-house, which has now been installed in a B-segment demonstrator vehicle.
