Aachen, Germany-based FEV has announced that its transmission and battery technology is being used in a PHEV that is now in series production. The unspecified vehicle has a 10 kWh battery pack and an electric range of about 30 miles. FEV was involved in developing the battery hardware and software from the development of the concept through testing and validation.
“Our spectrum of competence consists of every phase of development, from the concept work and development of modules and battery packs to the manufacturing and testing of the battery and, eventually, the integration and certification for series production,” says Dr. Michael Stapelbroek, Department Manager, Hybrid and E-Mobility.
FEV has been operating its own EV fleet since 2010, and gathering vehicle and battery measurement data, which it uses for its development of alternative drives. Over the past few years, the company has completed some 65 electrified powertrain development projects and about 20 battery projects, including water-cooled PHEV batteries and passively cooled packs for pure EVs.
“The core system for the battery development is our own mature battery management system (BMS), now in its third generation, that together with optimized algorithms allows a very reliable and stable control of the battery,” explains Dr. Stapelbroek. The BMS consists of a central control system, a master circuit board, and one decentralized measurement unit for each battery module, the slave circuit board.
