Want To Know How Much Your Volt Charge Will Cost?

General Motors, through its OnStar division, is testing an app capable of telling Chevrolet Volt owners how much it costs to charge their battery – and compare the Volt’s energy use with the total energy consumed in their home by day, month or year.

The new app, called EcoHub, will initially be tested with and available to residents of the Pecan Street demonstration project, a smart grid living community in Austin.

“For the first time we’re able to put one of our Smart Grid solutions into the hands of actual consumers, thanks in part to our partnership with Pecan Street,” said Paul Pebbles, global manager, Electric Vehicle and Smart Grid Services. “Down the line, we hope this app can be a beneficial tool for all drivers of electric vehicles.”

The EcoHub app works by pulling overall home energy usage data, provided by an energy data source, such as a utility or smart meter company. The app also collects Volt charging information from OnStar subscribers and Volt owners who opt in for EcoHub. The energy use data is then aggregated to show vehicle owners exactly how much energy is being used on a daily, monthly or yearly basis, while showing what percentage of that energy went to charging the Volt.

Based on electricity rates, the data is broken down to show the cost of both total energy usage and Volt charging energy use.

According to the U.S. Environmental Protection Agency, the 2013 Volt can travel an average of 38 miles on one full electric charge before its on-board gas-powered electric generator seamlessly switches on.

“We’ve found that Volt owners love to keep track of and compare their personal driving stats, like electric miles driven for example,” said Cristi Landy, Chevrolet Volt marketing director. “The EcoHub app is another great example of using the vehicle’s embedded technology to provide Volt owners with useful information.”

In addition, the EcoHub app will include a “Ticker” screen that shows drivers the national values for Total Miles Driven, Total EV Miles Driven and Gallons of Fuel Saved.

“The ‘Ticker’ screen is a nice addition because it allows drivers to see that they are part of a national effort to reduce fuel use by contributing to the growing number of electric miles driven,” said Pebbles.

While the app will be tested with and only be available to Volt drivers in the Pecan Street project at first, OnStar hopes to make the app available for all Volt owners once the pilot project is completed.

OnStar’s Smart Grid research is made possible with the help of the U.S. Department of Energy.

    so…how much?!?

    I have an eMonitor installed that can do this today.

    Is this application available for real computers or just phones?

    54kw a day? Who the heck lives there? Maybe in the days of having 100 watt incandescent light bulbs in every socket with half of them left on all day!

    I just double checked my bill. 20Kw a day. (Ranch house, about 2300 sq ft.)

    I don’t think many people who are really trying to be green are eating 54Kw a day. (And I’ll admit, I have a long way to go before I feel I have done my best to conserve.)

    Well the pilot program is in Austin Texas so maybe they run the central air a lot. Plus the volt isnt exactly cheap maybe there house is practically a mansion.

  • vikingted

    In summer I use ~20 to 25 kW-Hrs a day, in winter our usage goes up somewhat ~35 or so. We set the a/c to start once we get to 80F and the heater to turn on at 65F. This is 2600+SF home in CO.

    The “example” home is freakishly power hungry at 17,000 kWh per year (1426 kWh per month). That’s well over twice my own family’s consumption for our 4200 sq ft home in the mid-Atlantic.

    That said, the EcoHub software looks interesting.
