Battery-electric vehicles offer the possibility for local emission-free mobility. Unfortunately, electric batteries still suffer from well-known disadvantages like limited capacity, high production costs, long charging times and limited performance at low and high temperatures. This situation leads to a very low market-share of BEVs, although vehicles with high technical maturity arc available on the market. These disadvantages can be compensated if the vehicle is additionally equipped with the combination of a small internal combustion engine and a generator. These, so called Range Extender Modules, are a promising technology for the breakthrough of electric vehicles in the segment of micro and small cars. Several concepts for range extended electric vehicles with different system complexities like series-hybrid or parallel-hybrid powertrains are under discussion. KSPG and FEV have developed a range extender module for subcompact electric cars. The module was designed to be consistent with the serial hybrid drive option, consequently without mechanical interconnection to the drive shaft. This concept is beneficially suited for small electric 'city cars'. Several publications have already highlighted the particularly important NVH criteria of battery electric vehicles, the unique layout derived from these and their technical implementation. Considering quiet electric cruising the real challenge regarding NVH of an internal combustion engine (ICE) still persists and asks for innovative and feasible ideas like the 'FEVcom' (Full Engine Vibration Compensation System). This new technology has been introduced based on a 90° V2 engine, which allows a very compact design, suitable for an underfloor installation in a sub-compact vehicle. The ICE is integrated together with two tailor-made, highly efficient PMSM generators and a common cooling circuit in a combined housing.
