Boosts MPG in hybrids and range in electric vehicles by 20 to 70 percent

GREENWICH, Conn. & BOSTON--Electric Truck, LLC (ET) and Tufts University’s Office for Technology Licensing and Industry Collaboration (OTL&IC) today announced that ET has exclusively optioned commercial rights to a technology that can recharge the batteries of any hybrid electric and electric-powered vehicle while it is driven.

The Tufts-developed technology could increase by 20 to 70 percent the miles per gallon or total driving range performance of vehicles like the Honda Civic, Ford Escape, and Toyota Prius hybrids and the Tesla Motors and Phoenix Motorcars electric vehicles.

This cost-effective invention harnesses the movement of the vehicle to generate electricity that is used to recharge the battery continually while the vehicle is in motion.

Since the technology actively uses the weight of a vehicle for energy recovery, it could help speed the expansion of the hybrid and battery electric vehicle market from cars to vehicles of greater size, weight and payloads, such as SUVs, pickup and delivery trucks, mail trucks, school and city buses and other light and medium duty trucks. Trucks are a large market segment based on commercial need and also represent some of the biggest sources of emissions.

“We are extremely happy with Tufts’ development in this area, and see sales to the fastest growing market segment of hybrid vehicles to be a highly desirable way to contribute toward global climate change mitigation and petroleum independence,” said ET co-founder and CEO David Holst-Grubbe. “This deal puts ET in a unique position to serve high-growth markets with meaningful incremental benefit, without having to re-design existing vehicles.”

Tufts engineering professor emeritus Ronald Goldner and colleague Peter Zerigian developed this technology within the School of Engineering and received additional support in subsequent years from Argonne National Laboratory.

OTL&IC Associate Director Martin Son said, “Prof. Goldner and Mr. Zerigian were passionate about the need to lower greenhouse gas emissions and provide some relief to individuals and industry from the expensive and unpredictable costs of gasoline and diesel fuels. They were innovators who came up with this idea more than a decade ago and were truly ahead of their time."
