Mining giants’ battery challenge on
A global challenge has been launched by three of the world’s largest mining companies for technology innovators to develop concepts for new large-scale haul truck electrification systems to reduce the time required to charge large trucks and increase overall productivity. BHP, Rio Tinto and Vale, the founding patrons of the Charge On Innovation Challenge, together with Austmine, Australia’s Mining Equipment, Technology and Services (METS) industry body, are looking for innovations to deliver electricity to large battery-electric haul trucks quickly and efficiently. The mining industry requires multi-megawatt scale fast-charging concepts capable of delivering around 400kWh to charge and propel a truck within the truck’s haul cycle of load, travel, dump, return and queue. BHP Minerals Australia president Edgar Basto says he…
