Stock Photo - 25 September 2020, Saxony-Anhalt, Sandersdorf-Brehna: A system for splash water for the simulation of puddle passages of electric cars in the new test and development centre for vehicle batteries. In the approximately 12,000 square meters and thus largest center worldwide, high-performance batteries for electric cars are tested. A whole arsenal of tools is waiting for the batteries. From squeezing, dipping, heating, deep-freezing to shaking, treating with dust and salt to controlled short-circuiting, all energy storage devices are pushed to their limits. In Saxony-Anhalt, FEV has had a test center for conventional combustion engines in the automotive industry for almost ten years.
