Voltabox Systems for Mining Application
Voltabox of Texas, a manufacturer of advanced lithium-ion battery systems, has partnered with Komatsu Mining Corporation to replace the latter’s lead-acid and diesel engine-powered vehicles with Voltabox lithium-ion batteries.
The initial project was the Battery Hauler (BH 18/20), an underground vehicle capable of hauling up to 20 tons of material such as coal from underground mines. This electrically driven vehicle is being retrofitted with a 250V 160kWh lithium iron phosphate (LFP) battery system installed in a thermally controlled IP65 rated enclosure.
Lithium-ion batteries have significant advantages over traditional lead-acid batteries. Lithium-ion has a much longer life, does not outgas hydrogen or leak acid, provides better overall performance, weighs 40% less within same volume, can be charged in one hour or less, and lowers the customer’s battery inventory on hand.
The first lithium-ion-powered Battery Hauler was delivered in June 2017 for field validation, and is currently being tested in an underground mining operation. Additional Battery Hauler battery systems will be delivered later this year. Voltabox and Komatsu are already working on the next project to replace a diesel-powered vehicle with lithium-ion batteries, which is slated to be released by the end of 2017.
Voltabox AG will be exhibiting at The Battery Show Europe, 15-17 May 2018, at booth #176.
