OnStar EcoHub

OnStar 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 app initially will be tested with and only be available to Volt drivers in Pecan Street smart grid project in Austin, Texas, but OnStar hopes to make the app available for all Volt owners in the near future.
