Colorado Firm Claims the First V2G for Battery Trucks

Boulder Electric Vehicle chose last week’s ACT Expo 2013 in Washington, D.C. to talk up a demonstration of bi-directional DC fast charging with Michigan’s Coritech Services. The test, Bouldersays, makes it “the first electric truck company ever to successfully implement Vehicle-to-Grid (V2G) charging.”

Boulder is demonstrating vehicle-to-grid technology using a 100% battery electric flatbed utility truck with a 72-kilowatt-hour lithium battery pack and a 60-kilowatt DC fast charge system by Michigan’s Coritech Services.

Boulder and Coritech are using a Boulder battery electric flatbed utility truck with a 72-kilowatt-hour lithium battery pack and a 60-kilowatt Coritech DC fast charge system.

“Demonstrations are seeing charger rates of 150 amps during charge or discharge on the 360V nominal battery pack,” Boulder said Tuesday.

“We recognize the importance of V2G in turning EVs into energy storage for the grid,” said Boulder CEO Carter Brown. “We now have a solution ready for immediate deployment that will allow 50 electric trucks to offer 3 megawatts of energy on tap.”

Military Implications Too

“ACT Expo is the perfect forum,” he said, to show it.

“V2G is one of the key applications of smart grid technologies which will help realize the economic value of mass deployment” of EVs,” Boulder says.

DoD sees V2G as a way to protect the grid.

The system on show in Washington, Boulder said, is based on the interface specification for the Pentagon’s SPIDERS Phase II program (SPIDERS stands for Smart Power Infrastructure Demonstration for Energy Reliability and Security). Southwest Research Institute supplies grid aggregation service between the Coritech gear and the grid.

“We are proud to provide system solutions today for the realization of V2G DC Fast Charging and to be working with Boulder Electric Vehicle to ensure the entire system works together flawlessly,” said Russ Ristau of Coritech.

The companies are working toward a further V2G demonstration late summer 2013 at Fort Carson, Colo.
