Until last year, the Komatsu dumper truck chugged around the cement works quarry powered by its Diesel engine. In a few months, it will be expected to do the same job running purely on electricity. (Copyright: Andreas Sutter, Lithium Storage GmbH)
A Swiss consortium of companies is constructing the largest electric vehicle in the world - in record time. The prototype is not intended as a dainty little exhibition piece for trade fairs, but rather for hard labor in the quarry. Experts from Empa are in charge of its operational safety. It will be the largest electric vehicle in the world: weighing in at 45 tons when empty plus 65 tons of loading capacity - and a battery pack boasting 700 kWh of storage capacity. That's as much as eight Tesla Model S vehicles. The driver has to climb nine stairs to get to work and the e-mobile's tires measure almost two meters in diameter. Not everything on the vehicle is new, however: the monster electric vehicle is based on a used Komatsu dumper truck, which is being disassembled and reconstructed at Kuhn Schweiz AG in Lommis.
