PRODUCT FOCUS been replaced by an energy storage system consisting of four batteries, each with 16 stacks, which in turn consist of 24 Shenzen Westart NCM cells. The total budgeted costs for the prototypes are more than three million Swiss francs (CHF). Should the project be successful, a second eDumper is expected to cost no more than half that amount. This is the first vehicle of this performance class to be constructed in this manner, capable of handling 13% gradients when fully laden in the harshest environmental conditions, and with 700kWh capacity batteries that can handle the 20 downhill runs, the batteries are charged by 40kWh, making the vehicle a net electricity exporter or Plus Energy vehicle. This surplus is estimated at up to 200kWh per vehicle per day. Depending on the success of the project, currents up to 3 000 amperes. During each of The Volvo CE electric site research project aims to use electricity instead of diesel to power machines in a quarry. Ciments Vigier SA already envisages a equipment throughout Europe, is also possible additional order and in the longer considering other applications, such as term might operate up to eight 100% electric tunnel-building or construction work in vehicles. Kuhn Schweiz AG, a subsidiary residential areas which are sensitive to of the KUHN group, which sells Komatsu exhaust gases and noise. ■ References • Equipment World. 2016.
