As a new kind of range extender, the free-piston linear generator (FKLG) makes electric vehicles more flexible
Flexibility in respect of fuel types, compact dimensions and high efficiency combined with low emissions – these properties characterise the free-piston linear generator (FKLG), the brainchild of engineers at DLR. This animated film (in German) provides an insight into the way this new kind of range extender works.
