Systems and Components for E-Mobility

Capacity Area A1 addresses technical challenges related to storing electrical energy such as battery performance, reliability, charging time, lifetime and costs. These challenges are the main barrier for introducing electric propulsion and auxiliaries in automotive applications. In particular, Capacity Area A1 focuses on electric storage solutions for rail, bus, construction, agricultural or municipal utility vehicles, thus addressing the needs of the niche automotive and railway industries in Switzerland. The established Swiss Battery Research Platform with battery testing facilities at BFH, Empa and NTB provides essential research infrastructure for the development of battery systems for specialized vehicles. Research activities also include power electronics for batteries, e.g. to interface propulsion and inductive charging systems.
