E-Dumper: The World's Largest Electric Vehicle

摘要

To this day a diesel-powered dumper is used to transport lime- and marlstone from a higher-lying mining area down to the cement factory at Ciments Vigier SA in Pery. The dumper is being fully electrified by Lithium Storage GmbH and Kuhn Group S.A. by replacing the diesel engine with an electric motor and a 700 kWh battery system. The so called E-Dumper acts as a semi-autarkic vehicle by storing braking energy in the batteries while hauling limestone downhill. The recuperated energy is subsequently used to displace the vehicle from the valley to the hill. The E-Dumper will be the world's largest battery electric vehicle (BEV). The cells have been passed by UN 38.3 tests (test items: altitude, thermal, vibration, shock, external circuit, impact, forced discharge). Empa is responsible for the tests and development of battery cells and module configuration: CT images, short-circuit behaviour as well for the safety and risk analysis of cells and battery management system. The E-Dumper Project supports the electrification of mobility. The project is supported financially by the SFOE through its pilot and demonstration programme.
