Chevrolet Volt battery gets and eight-year, 100,000-mile warranty

Posted on 19 July 2010. Tags: battery, Chevrolet, Volt

The Chevrolet Volt electric vehicle with extended range will provide customers with 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 percent of which are designed and engineered by GM, in addition to the thermal management system, charging system and electric drive components.

The Volt is the only electric vehicle that can operate under a full range of climates and driving conditions without limitations or concern about being stranded by a depleted battery. It has a range of about 340 miles and is powered with electricity at all times. For up to the first 40 miles, the Volt is powered solely by electricity stored in its 16-kWh lithium-ion battery, using no fuel and producing no emissions. When the Volt’s lithium-ion battery runs low, an engine/generator seamlessly operates to extend the driving range another 300 miles on a full tank of fuel.

GM engineers have completed more than 1 million miles and 4 million hours of validation testing of Volt battery packs since 2007, as well as each pack’s nine modules and 288 cells. The development, validation and test teams have met thousands of specifications and validated each of the Volt battery’s components.

GM’s Brownstown Township plant, which began building prototype batteries in January, soon will begin regular battery production.

“We’re moving fast to deliver for the customer and ensure the Volt launch stays on track,” said Nancy Laubenthal, plant manager of the Brownstown Battery Plant. “Last August we announced the investment in the Brownstown facility and in January built our first completed battery pack. Now we are finishing pre-production batteries and soon we will begin building production batteries for Chevrolet Volts that will be delivered to dealers before the end of the year.”

Last year, the U.S. Department of Energy selected 45 companies, universities and organizations in 28 states – including GM’s Brownstown plant – to share more than $2 billion in awards for electric drive and battery manufacturing, and transportation electrification. Nearly half of the awards are designated for cell, battery and materials manufacturing facilities in Michigan.
