Abstract
A mining haul truck driven by electrical wheel motors is powered by a trolley power system during an uphill climb. Retard energy captured during braking action on either the uphill climb or downhill descent is stored by an on-board electrical energy storage system. Electrical power is supplied from the on-board electrical energy storage system to reduce the peak power demand on the trolley power system during the uphill climb. One implementation of the on-board electrical energy storage system uses an ultracapacitor system.
