AMP Holding Inc. says its medium-duty all-electric step van has completed accelerated durability testing at the Transportation Research Center, an independent testing facility. AMP manufactures alternative fuel vehicles under the Workhorse brand in Union City, Ind.
‘The testing is key validation for the durability and engineering integrity of the AMP all-electric system,’ says Stephen Burns, CEO of AMP.
TRC Inc. performed the testing on AMP's behalf, to ‘simulate the rigors of package delivery.’ The testing ran for 4,000 miles during the Ohio winter from February to April, including 2,000 miles at curb weight and 2,000 miles fully loaded. Each durability cycle was just under 10 miles long and consisted of traversing a series of resonance, chatter and impact bumps; a series of moderate washboards, frame twists, and dips; inverted chuckholes; stopping and starting on a 20% brake slope; lock-to-lock figure-8 maneuvers; a short slalom course; and gravel roads.
The all-electric system in AMP's 19,500 lbs. GVW vehicle produces 250 kW, and the vehicle offers 100 kWh of energy storage. The vehicle's range on a full charge is approximately 100 miles.
AMP acquired the Workhorse brand and the associated factory facilities from Navistar subsidiary Workhorse Custom Chassis LLC in March.
