Design of future concepts and variants of The Free Piston Linear Generator

The Free Piston Linear Generator (FPLG) is capable of transforming chemical stored energy into electric energy by means of an internal combustion process. As explained in [6], it achieves high degrees of efficiency at full and particularly at part load. Besides a wide area of applications, the FPLG especially meets the requirements of vehicles with range extenders or serial hybrid drives. Hence, this publication deals with the explanation of different package concepts of the FPLG for the use in electric vehicles with a generating unit. For this purpose, two different FPLG modules for future production cars are designed and the package for different combinations are illustrated in a vehicle model. This comparison presents an outlook for possible vehicle concepts of the future.
