Concurrent Picks UL-Certified Bi-Directional Multi-Port Inverter

New Jersey’s Princeton Power Systems is talking up selection of its GTIB-30, a UL-certified, bi-directional multi-port inverter, as the basis for charging stations for the Pentagon’s vehicle-to-grid trials at LAAFB, the Los Angeles Air Force Base.

PrincetonPower-logoThe Pentagon recently clarified plans for initial V2G tests at four military bases, with LAAFB prominent among them (F&F, June 3).

V2G allows for the electric grid to be able to draw on the energy stored in multiple electric vehicles in times of peak demand. Put another way, “It is intended that ancillary service driven cost reduction and revenue will partially offset EV fleet lease expense with the potential to improving energy security on base,” according to a Princeton Power release.

‘A Vital Role’

Concurrent Technologies Corp, Princeton explains, “is responsible for overall execution of the LAAFB effort… Working directly with electric vehicle OEMs and third-party fleet-management software aggregators, Princeton Power played a vital role in developing the ground-breaking solution in order to compete in the electrical utility ancillary service markets.

V2G is a relatively simple concept, but complex in its execution, requiring the active participation of and cooperation between numerous organizations and the coordination of complex technologies and software.

“During typical usage,” Princeton explains, “the charging stations will charge the electric vehicles directly from the local utility grid enabling LAAFB personnel to utilize the electric vehicles as transportation within the base.

“When called upon, and when connected to the electric vehicle, the bi-directional charging station will switch power flow directions quickly in order to support vehicle-to-grid energy request by discharging the electric vehicle’s on-board battery.”

‘Just the First Step’

Princeton Power’s “experience with microgrid systems and bi-directional inverters is key for the long term success of this project,” CTC’s Clark Boriack says in Princeton’s LAAFB announcement. “LAAFB will be DoD’s first deployment of bidirectional inverters used for electric vehicle fast charging on such a scale; as well as a major milestone for the company’s push into the electric vehicle bi-directional DC fast-charging station application space,” Boriack said.

“This is just the first step towards deploying our electric vehicle DC-fast chargers across the nation. We will be helping push the electric vehicle frontier by making it feasible for drivers who work or visit to charge their cars without taking large amounts of time out of their day,” said Princeton Power co-founder and chief strategy officer Darren Hammell.

Initial Dozens Could Lead to Thousands of Grid-Connected EVs

The U.S. Department of Defense is deploying several dozen battery electric and plug-in hybrid electric vehicles around the country, with a view to demonstrating how V2G – vehicle-to-grid – technology can help take the strain off of the electric grid during peak hours by utilizing the vehicles’ batteries.
