An automotive supplier plans to roll out a power regeneration trailer designed to recharge electric cars while they drive.

Known as the PRU (power regeneration unit), the self-propelled trailer will enable electric vehicle (EV) owners to take their cars on much longer trips and charge them in locales where charging infrastructure does not yet exist. The product, which houses a battery and a small internal combustion engine, is engineered by Electric Motors and Vehicles Company (EMAV).

EMAV executives cited the recent J.D. Power report on electric vehicles as proof such regeneration trailers are needed. “J.D. Power says that sales of electric vehicles will hit only two million in 2020 – that is slow adoption, much due to the current range of these vehicles,” noted Wil Cashen, founder and president for EMAV. “Our goal is to move the marketplace beyond the first generation of electric vehicles to more powerful and rugged cars that also have endurance. This will evolve the electric car paradigm from a supplemental to a primary car for consumers.”
