While visiting the Innovation Showcase at CTIA 2012, we ran into Nick Pudar -- OnStar's VP of Business Development -- who was kind enough to give us a few minutes of his time. We sat in the LTE Skype-enabled Chevy Volt on display and discussed such topics as OnStar FMV, RelayRides and smart grids -- wherein power utilities can (with the customer's consent) send a signal to a vehicle to control when it charges. The idea is to allows utilities to maximize grid efficiency and minimize power spikes while giving customers options for when to charge the vehicle -- like when the rates are the lowest or when the power generated is coming from renewable energy, for example. Pretty neat stuff, eh? Watch our video interview for all the (pardon the pun) juicy details.
