V2G Hybrids, Electric Vehicles Could Feed Power to Electric Grid

Paying for parking is an everyday annoyance, but owners of hybrid and electric vehicles could potentially be paid to park. A new system could allow owners of such vehicles plug into the electric grid and earn extra cash.

At last week’s annual American Association for the Advancement of Science convention, researchers showed off the AC Propulsion e-Box — essentially, an electrified Scion xB. While that may seem special enough, it was soon revealed that the car was capable of functioning in a vehicle-to-grid (V2G) manner.

“This is the first vehicle that’s ever been paid to participate in the grid — the first proof of concept vehicle,” said Ken Huber, technical development director at PJM Interconnector.

In theory, V2G vehicles could — when plugged in — feed energy stored within their battery packs back into the electric grid. V2G vehicles would need to be plugged into a so-called “smartgrid,” which allows an electric utility to manage the entire grid. When the grid needs more power to combat a surge, the power could potentially be tapped from hybrids and EVs instead of traditional powerplants. Owners could then potentially receive credits for their vehicles’ involvement.

“It’s a technology that is very good at meeting a need we have, and there’s growing interest among auto companies to develop V2G vehicles,” said Willett Kempton, leader of the University of Delaware’s V2G project. Reportedly, BMW, Renault/Nissan, and Mitsubishi are all interested in developing V2G-capable vehicles.
