World’s largest electric vehicle now in operation

Swiss universities teamed up with Swiss industry partners to build the world’s largest electric truck. The eco-friendly eDumper dump truck is now in operation at a quarry in the Bernese Jura.

The world’s largest electric vehicle has an empty weight of 58 tonnes and a payload of 65 tonnes. Designed over the past 18 months, it is an example of applied research in Switzerland at its best. It is equipped with a 4.5 tonne battery – the largest ever produced for an electric vehicle – and will save a record amount of CO2 for a vehicle of its size: up to 1,300 tonnes of C02 and 500,000 litres of diesel over the next 10 years.

The eDumper was developed by the Bern University of Applied Sciences (BFH), the NTB Interstaatliche Hochschule für Technik Buchs, and the Swiss Federal Laboratories for Materials Science and Technology (Empa), together with a group of industry partners. It is now in operation in the quarry of Vigier Ciment in the canton of Bern, where it will transport more than 300,000 tonnes of lime and marl rocks per year from a higher mining area to a lower processing plant.

Designed on the basis of a diesel-powered Komatsu HD 605-7 dump truck, its batteries are charged by recuperation of braking energy during descent. According to Empa, the electricity generated in this way will be enough for the empty return journey uphill to the mining area, making the eDumper a zero-energy vehicle.
