After working with Coritech Services on a bi-directional DC fast charging solution, Boulder Electric Vehicle says it's now the first-ever electric truckmaker to successfully implement Vehicle-to-Grid (V2G) charging. The two companies displayed an electric flatbed utility truck equipped with a Tesla-sized 72-kWh lithium battery pack and a Coritech 60-kW DC fast charger at the Alternative Clean Transportation Expo in Washington, DC this week.
There's a lot of power being produced in V2G charging – their current demonstrations are seeing charger rates of 150 amps during charge or discharge on the 360-volt nominal battery pack. A bi-directional V2G fast charge happens when the electric current can be used for two functions – charging the EV's battery and discharging the power for use outside of the vehicle – by a utility that needs more electricity, for example.
In its press release (see below), Boulder EV says that V2G is a key application of smart grid technologies that helps realize the economic value of mass deployment of EVs. V2G can manage the power stored in the battery between the utility, vehicle and charge points. Southwest Research Institute will be supplying the grid aggregation service between the Coritech's EV supply equipment and the grid. Boulder EV and Coritech are working toward a demonstration in late summer 2013 at the Fort Carson US Army installation near Colorado Spring, CO. Boulder EV thinks the demonstration can work within the Department of Defense's larger vision of a mass scale EV deployment.
Boulder Electric Vehicle and Coritech Services have demonstrated bi-directional DC fast charging, making Boulder Electric Vehicle the 1st electric truck company ever to successfully implement Vehicle-to-Grid (V2G) charging.

Boulder Electric Vehicle and Coritech Services have demonstrated bi-directional DC fast charging, making Boulder Electric Vehicle the 1st electric truck company ever to successfully implement Vehicle-to-Grid (V2G) charging. Boulder EV and Coritech Services will both be attending the Alternative Clean Transportation ("ACT") Expo in Washington DC, June 24th through June 27th, where together in booth 216 they will be highlighting their outstanding achievement of electric vehicle bi-directional charging. There will be on-site demonstrations revealing their turnkey solution to V2G charging utilizing Boulder EV's 100% Electric Flatbed Utility Truck equipped with a Lithium 72 kWh battery pack and a Coritech 60kW DC Fast Charger System. Current demonstrations are seeing charger rates of 150 amps during charge or discharge on the 360V nominal battery pack.
"The ACT Expo is the perfect forum of industry leaders to introduce Boulder Electric Vehicle's proven V2G solution with Coritech Services," shared Carter Brown, Chief Executive Officer of Boulder Electric Vehicle. "We recognize the future importance of V2G in strengthening the value proposition of the Electric Vehicle, and we now offer a turnkey solution that is ready for immediate deployment."
V2G is one of the key applications of smart grid technologies which will help realize the economic value of mass deployment of Electric Vehicles. Communication and management between the utility, vehicle and charge points are essential aspects in achieving V2G. Boulder Electric Vehicle offers a wide range of medium and heavy duty fully electric vehicles ideally suited for today's progressive fleet. Coritech Services offers DC Fast Chargers capable of bi-directional charging and discharging.
"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," shared Russ Ristau of Coritech Services Inc.
The system developed has been based on the interface specification for the SPIDERS Phase II program and was implemented, developed and finalized independently by Boulder Electric Vehicle and Coritech Services. Southwest Research Institute will be supplying the grid aggregation service between the Coritech EVSE and the grid. Due to the success of this turnkey system, the companies are working toward a demonstration late summer 2013 at Fort Carson. This demonstrated solution supports a larger vision of the Department of Defense in the mass scale deployment of Electric Vehicles.
