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. A range extender converts liquid fuel 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.MAHLE Powertrain has developed a production feasible solution based on the range extended electric vehicle (REEV) philosophy. Having successfully developed its own Compact Range Extender Engine in-house, a fully functional demonstrator vehicle has now been built to provide convincing proof of this approach. Starting from a clean-sheet, the MAHLE Range Extender has been designed to be light (65 kg including generator) and compact.
