FEV works with battery suppliers on internal development projects and on cooperative projects, utilizing its experience with both Passive and Active balancing techniques. FEV provides expertise in the development of either air- or liquid-based thermal management systems based on Finite Element Analysis (FEA) simulations. The company’s engineers can develop cell specific battery algorithms as well as design and implement complete packs, including performance simulation, cell selection and module / pack design.
Storage and management of electrical energy in hybrid and electric vehicles is a key element in advancing this technology, and special consideration must be given to electrical, thermal and mechanical loads, which must be kept in allowable ranges over all cells that make up the battery. Proper thermal management is the key to maximizing the effectiveness of Li-Ion batteries.
These considerations make extensive testing necessary, and FEV offers a comprehensive suite of design, development, testing and validation capabilities to its customers. FEV also applies CFD simulation for analysis of the thermal behavior of battery cells/modules/packs.
FEV engineers routinely work to develop a client’s battery management system and, in other cases, they are asked to adapt an internally developed system, such as the FEV designed and developed LiiONMAN system, to support customer needs. FEV’s capabilities include overall pack cycling, testing and validation of safety systems, and testing capabilities up to 1000A / 900V for a total of 250kW.
The FEV Group is an internationally recognized powertrain and vehicle engineering company that supplies the global transportation industry. FEV offers a complete range of engineering services, providing support across the globe to customers in the design, analysis, prototyping, powertrain and transmission development, as well as vehicle integration, calibration and homologation for advanced internal combustion gasoline-, diesel-, and alternative-fueled powertrains.
FEV also designs, develops and prototypes advanced vehicle / powertrain electronic control systems and hybrid-electric engine concepts that address future emission and fuel economy standards. The FEV Test Systems division is a global supplier of advanced test cell, instrumentation and test equipment. The FEV Group employs a staff of over 1,800 highly skilled specialists at advanced technical centers on three continents. FEV, Inc. employs approximately 300 personnel at FEV’s North American Technical Center in Auburn Hills, MI.
