Boulder Electric Vehicle Demonstrates Vehicle-to-Grid (V2G) Charging Across the Nation

The US Army Corp of Engineers and the SPIDERS project signed off on verifying full charge and discharge of the vehicle at 60 kilowatts of power.

The US Army Corp of Engineers and the SPIDERS project signed off on verifying full charge and discharge of the vehicle at 60 kilowatts of power.

Electric truck manufacturer Boulder Electric Vehicle announced that it has already successfully demonstrated Vehicle-to-Grid (V2G) at three different locations in Michigan, Colorado and California.

The 60 kW system, with Coritech Services’s bi-directional chargers, utilize new J1772 DC Combo connectors and is able to charge/discharge a battery pack in about an hour.

Boulder EV CEO Carter Brown stated:

“This first success happened in the labs of our EVSE partner Coritech Services.  When we finally saw the power going in and coming out at the maximum allowable amounts as per the J1772 DC Combo connector spec, we were all as giddy as school kids.”

The first demo transpired in Royal Oak, Michigan, on June 14, 2013.  But of interest here is that 60 kW is the “maximum allowable amounts as per the J1772 DC Combo“?

More Than Capable...No Need to Worry

More Than Capable…No Need to Worry… But We Can Still Add V2G Just to Be Sure

The second major milestone came on July 25, 2013 in Ft. Carson, Colorado and the third in Los Angeles on August 13, 2013.

According to the press release, it seems that Boulder Electric Vehicle wants to build its future around V2G capability, which is interesting since, to date, nobody explored this in depth in commercial operation.

“As of today Boulder Electric Vehicle is the only electric truck manufacturer in the world to demonstrate working vehicle-to-grid charging at 60 kilowatts of power outside of the SPIDERS project in Fort Carson, Colorado.  Boulder EV and Coritech Services will be providing demonstration units comprised of a charger and a truck to private utility companies beginning fall of this year.  Boulder EV will also be showcasing a V2G capable truck, alongside a Coritech DC quick charger, at the Plug-In 2013 Conference & Exposition in San Diego, CA.  The conference kicks off September 30th and runs through October 3rd.  For those interested in scheduling a demonstration of Boulder EV’s trucks performing V2G charging with a Coritech EVSE please contact them directly to set up reservations.”

    Interesting concept; however, V2G adds little value to consumers. Why would anyone allow their batteries to be cycled by a utility (and therefore shorten their lifetime for vehicular use)?

    It would make more sense to repurpose battery packs no longer useful for automobiles into modules suitable for supplementing the grid on a portable level.

  2. Bill Howland says:

    Other than another flimsy excuse to install increasingly unwanted spying Smart Meters, I’ve never heard a convincing explanation why V2G is remotely necessary. Correcting transient short-term load fluxuations are inconsequential since there are no billing implications. Speaking of which, Utilities aren’t interested in them either, unless of course you pay (bribe) them.

    Demand Load shifting (for those few utilities that actually need it) by time of day metering (can and has been traditionally totally mechanical) , or load shedding arrangements with larger customers.

    “warning: the grid is running low on power – please drive to the nearest discharge station”

    “Why would anyone allow their batteries to be cycled by a utility?”
    Good point.
    I would add that each discharge/recharge ends in a net loss of energy (hence money) even if the EV owner is fully reimbursed for his kWh.
    Add that to the nail in the battery’s coffin on each cycle.

  5. Rick Danger says:

    I’m more interested in V2H (vehicle to home) to alleviate those summer power outages.

  6. Andrew says:

    V2G is a great way to generate incredible value for the consumer with ancillary services. A 60kW system plugged in 18 hours a day is worth at least ten thousands dollars over a 5 year life.

  7. nwdiver says:

    V2G will become increasingly critical especially if the cycle life of batteries improves faster than calendar life. Distributed storage will allow much greater penetration of distributed generation sources such as solar PV.
