Hybrids& E-Mobility

Hybrids and


Electrified powertrains have resulted in lower emissions and reduced carbon footprints for passenger cars and light-duty vehicles. FEV has been responsible for a large number of development programs for hybrid and all-electric powertrains as a turn-key development partner for international customers. Starting with start/stop systems, our experience comprises micro, mild, full and plug-in hybrids as well as battery electric vehicles (with and without range extender modules). FEV also engages in internal R&D projects to evaluate fuel cell technology for our clients. In combination with our transmission system experts, FEV has contributed a considerable number of advantageous hybridized transmission solutions. In all of our global development centers, we have employed rapidly growing teams and continuously extended our test facilities to meet these needs.



FEV offers the development of entire battery systems, including the Battery Management System (BMS) and battery testing. While FEV can access standard modules and its own BMS (FEV LiiONMAN), it also offers the services of new product development. Within the framework of a safety agenda according to ISO 26262, all of the required steps are taken from the technical specifications through the scheduling, completion and documentation of validation activities and reviewing of suppliers of safety-relevant parts. The FEV Battery Management System battery control unit (FEV LiiONMAN) combines the surveillance of all critical values with operational strategies to create a performance projection. This enables safe operation and optimized utilization of the cell’s capabilities.
