Used Chevy Volt batteries may find second life on electric power grid

General Motors and ABB Group will work together to develop pilot projects for re-using the batteries from the Chevrolet Volt electric vehicle, examining whether the batteries may be a source for renewable energy that could improve the effectiveness of wind and solar power generation. The opportunity is the basis of a memorandum of understanding recently signed between General Motors and ABB Group.

The two companies are collaborating to determine how the Volt's 16-kWh lithium-ion batteries can be used to provide stationary electric grid storage systems once the batteries have fulfilled their usefulness in customers' vehicles. The ultimate goal is to provide cost-effective, innovative solutions that will improve the efficiency of the country's electrical grid.

"The Volt's battery will have significant capacity to store electrical energy, even after its automotive life," said Micky Bly, GM executive director of electrical systems, hybrids, electric vehicles, and batteries. "That's why we're joining forces with ABB to find ways to enable the Volt batteries to provide environmental benefits that stretch far beyond the highway."

Bly announced the partnership at the EV Battery Tech conference Sept. 21, 2010 in Troy, MI. "Our relationship with ABB will help develop solutions that optimize the full lifecycle of the Volt battery," Bly said. The Chevrolet Volt electric vehicle with extended range will provide customers with a standard, eight-year/100,000-mile warranty on its advanced, lithium-ion battery. It is the automotive industry's longest, most comprehensive battery warranty for an electric vehicle, and is transferable at no cost to other vehicle owners.

The Volt's comprehensive battery warranty covers all 161 battery components, 95% of which are designed and engineered by GM, in addition to the thermal management system, charging system, and electric drive components.

ABB is the world's largest supplier of power grid systems and a leader in power and automation technologies.

Engineers and researchers from both companies are working together to study:

* Renewable energy storage: Power generated by wind and the sun can be stored in Volt battery systems and used when demand warrants.
* Grid load management: Utilities will be able to use the Volt batteries to store electricity generated during off-peak periods to supplement demand during high-peak operation. This will help utilities to better manage the grid, improving reliability and efficiency.
* Back-up power supplies for communities: Volt battery systems can store electricity that can be used by communities during power outages caused by storms or other natural disasters.
* Time-of-use Management: Industrial customers can store off-peak, lower-priced electrical power in Volt batteries for use during peak demand time of day for cost savings.
