As reported by General Motors
Brownstown Township, Mich. – The Chevrolet Volt electric vehicle with extended range will provide customers with an unprecedented, 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.
The Volt’s advanced, lithium-ion battery is designed to deliver the value, safety, quality, performance, durability and reliability Chevrolet customers expect. Key battery features include:
·Thermal management for durability and reliability: The Volt is the only mass-market electric vehicle with a battery that can be warmed or cooled. The battery is designed to provide reliable operation, when plugged in, at temperatures as low as -13 degrees Fahrenheit (-25 C) and as high as 122 degrees Fahrenheit (+50 C). In cold weather, the battery will be preheated during charging to provide full power capability. In hot weather – the most challenging environment for a battery – the Volt’s battery can be chilled during charging. The Volt’s liquid thermal management system can also be powered during driving by the battery or engine/generator.

- Diagnostics for safety and performance: The Volt’s battery management system continuously monitors the battery real-time for optimum operations. More than 500 diagnostics run at 10 times per second, keeping track of the Volt’s battery pack; 85 percent of the diagnostics ensure the battery pack is operating safely, while the remaining 15 percent keep track of battery performance and life.
- Cell design and chemistry for performance and efficiency: GM’s selection of a prismatic cell design and LG Chem’s manganese spinel lithium-ion chemistry is designed to provide long life and high power output, with a properly maintained temperature. This enables better vehicle acceleration and increased regenerative braking capability for improved vehicle efficiency.
- Energy management for durability: Fully charging or fully depleting a battery shortens its life. The Volt’s energy management system never fully charges or depletes the battery. The Volt’s battery has top and bottom “buffer zones” to help ensure long life.
