GM Upgrades OnStar to Power First Real-World, Smart Grid EV Pilot

OnStar is helping GM to pull off: offering a short-cut to connect electric vehicles (EVs) to the smart grid. GM yesterday announced the launch of a pilot program that can let utilities and customers skip the need to install physical smart grid points to manage recharging of their EVs. The new OnStar service will act as a remote brain, wirelessly tracking and governing the EV's charging behavior, coordinating the timing and billing, and potentially dramatically lowering the costs to extend smart-grid management features to EVs.

By skipping the need to install physical smart apparatus, the OnStar system can save utilities some $18 million per 1,000 customers, said Vijay Iyer, GM's director of communications for OnStar, citing GE estimates. To mesh OnStar's data services with utilities' internal information management systems, GM worked with GE, whose IQ Demand Optimization Services unit is used by utilities to monitor demand response systems.

This is important step for utilities which are busily, and expensively, building intelligent power and data devices in customers' garages, as well as at charging terminals, to referee how and when EVs will re-charge. Utilities don't want fleets of EVs drawing power on 95 degree summer afternoons when power is in short supply. Customers, likewise, will prefer the option of charging at night when power is much cheaper.
