Exactly three years since the day the Chevrolet Volt concept car debuted, GM yesterday manufactured the first advanced lithium-ion battery for a mass-marketed electric vehicle at GM’s Brownstown Battery Pack Assembly Plant.
“This is an important milestone for GM – and a critical step in bringing the Chevrolet Volt to market,” said GM Chairman and CEO Ed Whitacre. “The development of electric vehicles like the Chevy Volt is creating entire new sectors in the auto industry – an ‘ecosystem’ of battery developers and recyclers, builders of home and commercial charging stations, electric motor suppliers and much more,” Whitacre said. “These companies and universities are creating new jobs in Michigan and across the U.S. – green jobs – and they’re doing it by developing new technology, establishing new manufacturing capability, and strengthening America’s long-term competitiveness.”
The Volt’s battery pack is made up of multiple linked battery modules and more than 200 battery cells. The initial assembly area is where the prismatic-shaped cells are processed and installed by state-of-the-art flexible automated equipment into modules, which are then delivered to the battery pack main line. The battery pack main line area features an Automated Guided Cart (ACG) system that includes operations for thermal and electrical assembly, along with quality and dimensional checks. The main line is also where battery pack final testing, verification and packaging for shipment take place.
The Volt is set to officially go on sale this November. Overall, Volt production will be limited, at least through the first full year of production, but should eventually reach about 60,000 Volts per year.
