General Motors is developing a feature for its OnStar navigation service that will allow Chevrolet Volt owners to better match recharging patterns for the extended-range plug-in vehicles with the availability of renewable energy.

GM is working with utility company PJM Interconnection on the feature, in which OnStar users will know what percentage of a grid's power supply is coming from renewable sources such as wind. OnStar will be able to regulate the recharging activity for Volts according to peak wind time, which according to PJM is generally between 10 p.m. and 6 a.m.

GM is running demonstrations of the feature this week at the 2012 DistribuTECH Conference and Exhibition in San Antonio. GM will also work with Google at testing the OnStar feature on 17 Chevy Volts at Google's campus in Mountain View, CA. OnStar, which is available on 45 GM models, is used by 6 million subscribers in North America and China.

Volt Owners May Soon Get Charged with Renewable Energy

DETROIT – Chevrolet Volt electric car owners could soon charge with renewable energy using a new solution from OnStar.

The technology is enabled as OnStar receives a signal from PJM Interconnection that shows the percentage of available renewable energy on the grid. Data from this forecast is downloaded to the OnStar cloud, or Advanced Telematics Operating Management System (ATOMS). OnStar uses this signal to simultaneously manage the charging of many Volts and to match the renewable energy availability. A mobile app could also be used to alert customers when renewable energy is available.

OnStar and Google are working together to demonstrate the technology on the 17 Chevrolet Volts in Google's "Gfleet" based at the company's headquarters in Mountain View, Calif.

"This demonstration shows that in the near future customers will have a real signal of demand for renewable energy," said Nick Pudar, OnStar vice president of planning and business development. "As customers configure their Volts to favor renewable energy for their charging cycle, this real demand signal will influence utilities to tap into renewable sources."

The demonstrations are taking place this week at the 2012 DistribuTECH Conference and Exhibition in San Antonio. DistribuTECH attendees can see live demos at Booth 1543. OnStar will also be demonstrating the company's Demand Response and Time-of-Use Rate solutions.

PJM data shows that peak time for renewable energy generation from wind is generally between 10 p.m. and 6 a.m. With this in mind, it would be possible for customers to use OnStar's Smart Grid solutions to further reduce their carbon footprint and save money by charging during these off-peak times.

"Solutions like this one will ultimately lead to increased renewable energy generation and allow Chevrolet Volt owners to be a key part of that energy transformation," said Pudar.

If the renewable energy service goes into production, customers interested in using it would simply need to sign up. OnStar would then regulate their charging using the renewable energy signal.

The renewable energy technology is the latest addition to OnStar's suite of Smart Grid solutions. OnStar has also developed intelligent energy management technology solutions including:

■Demand response – This solution connects utilities to companies that have intelligent energy management products. These companies can use OnStar to manage energy use for Volt customers who opt in for the service. This future service allows the customer to save money on energy costs while enabling more efficient use of the electric grid.
■Time-of-Use (TOU) rates – OnStar can receive dynamic TOU pricing from utilities and notify Volt owners of the rate plan offers via email. Owners will be able to use OnStar to load the rate plans directly into their vehicle and access them to schedule charging during lower-rate periods.
■Charging data – OnStar also sends and receives EV data that helps utility providers without having to interface with the vehicle's electric vehicle supply equipment. This includes location-based EV data that identifies charging locations and determines potential load scenarios.
