Parcel carrier UPS says it plans to repower a considerable number of its van fleet with a locally-developed hybrid driveline as part of its global strategy to lower its carbon footprint.
Designed and developed by engineering consultancy Revolve Technologies, the hybrid driveline also serves to extend the useful service life of the company’s Mercedes-Benz Vario vans which are no longer in production.
Revolve Technologies used the Cenex 2015 Low Carbon event at Millbrook to present the hybrid drivetrain installed in a UPS Mercedes-Benz Vario van.
The hybrid system employs a Ford Focus diesel engine to act as a generator, which runs at one of three fixed speeds depending on demand. It is optimised for emissions and consumption at 1,300, 2,200 and 3,200rpm. The battery/power management system and P180 electric traction motor, which drives the rear wheels directly, are Magtec units made in Sheffield. During braking the traction motor becomes a generator, recovering energy by producing electricity which is stored in the batteries.
The new drivetrains will be installed in the vans by Tevva Motors of Hutton. The additional weight of the hybrid components is offset to a degree by using a lighter diesel engine, and the drivetrain has no significant effect on the vans’ payload.
