Comparison of range extender technologies for battery electric vehicles

The aim of this publication is a comparison of a wide selection of range extender technologies. Thereby a large amount of criteria are looked into. This assures that the comparison is feasible for a diversity of performance specifications. Hence an information level is achieved, that allows for a justified choice of technology according to the desired range extended electric vehicle concept.

Free piston linear generator in comparison to other range-extender technologies

The free piston linear generator is a new range-extender technology. It converts chemical energy into electrical energy by means of a combustion process and linear generator. Thereby the technology aims to have better properties than other range extenders. Therefore this publication deals with the explanation of the concept and the characteristics of a free piston linear generator and a comparison to other technologies. In order to compare the range extender systems, fuel cells, micro gas turbine and otto/wankel combustion, will briefly be presented, before being compared to the free piston linear generator.
