2.5-Liter Engine from PSI Allows for Smaller, Cheaper Batteries

Ohio’s Amp Trucks, proprietor of the venerable Workhorse brand, has filed a provisional patent for a new system that extends the range of electric vehicles while reducing the overall cost of typical battery electric powertrain.

The new E-Gen extended-range drive from Amp Trucks also includes a 2.0-liter engine from PSI.

The new E-Gen extended-range drive from Amp Trucks also includes a 2.0-liter engine from PSI.

The E-Gen Drive, Amp says, “is designed specifically for the package delivery vehicle market in which the diesel and/or gasoline-powered vehicles in use now stop and restart hundreds of time a day.”

“We believe that battery electric technology is an ideal fit for urban and suburban delivery routes and we understand fleet owner’s concerns about range anxiety and cost,” Amp CEO Steve Burns said in a release.

‘Consistent State of Charge’

“Our E-Gen Drive system will enable them to keep the batteries recharged to a consistent state of charge throughout the day,” he said. And, since we are able to use smaller battery packs, we can reduce the cost of the entire system.

Our E-Gen Drive trucks, with vouchers, offer a three-year payback and are now in the same price range as comparable gasoline powered trucks,” Burns said.

Amp is using 2.5-liter engines from Power Solutions International, and notes that PSI offers engine variants suitable for gasoline or gaseous (propane autogas or CNG/compressed natural gas) fuel operation.

The multi-fuel engines, said Amp CTO Don Wires, “function as generators. When the ignition is shut off, the engine automatically turns on and recharges the battery pack. When the ignition is turned back on, the engine turns off and the vehicle reverts to all-electric power.

‘It’s Not a Traditional Hybrid’

“The engine and the battery-powered motor are never in use at the same time,” he says. “It’s not a traditional hybrid, it’s an extended-range electric vehicle.”

The latest filing adds a new provisional patent to a list of intellectual property innovations that include U.S. patents 7,559,578 B2; 7,717,464 B2; D561,079 S; D561,078S, and 8,541,915 B2, Amp says.
