BROWNSTOWN TOWNSHIP, Mich. \u2013 Exactly three years since the day the Chevrolet Volt concept car debuted, GM today manufactured the first advanced lithium-ion battery for a mass-marketed electric vehicle at GM’s Brownstown Battery Pack Assembly Plant.<\/p>\n
\u201cThis is an important milestone for GM \u2013 and a critical step in bringing the Chevrolet Volt to market,\u201d said GM Chairman and CEO Ed Whitacre.<\/p>\n
GM announced last August a $43-million investment to prepare the 160,000-square-foot, landfill-free facility for production of lithium-ion battery packs for the Volt and other electric vehicles with extended-range capabilities. The plant is part of a wholly-owned subsidiary of General Motors called GM Subsystems Manufacturing LLC.<\/p>\n
In just five months, the Brownstown plant was converted from an empty facility to a production-ready battery manufacturing site. New machinery and specialized equipment have been installed and three primary assembly areas have been completed: battery module pre-assembly, final assembly and the battery pack main line.<\/p>\n
The Volt\u2019s 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.<\/p>\n
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.<\/p>\n
Initial battery production at Brownstown will be used to validate the plant\u2019s equipment and processes, and batteries will be sent to GM\u2019s Global Battery Systems lab in Warren, Mich., for testing. This spring, GM will begin shipping batteries to GM\u2019s Detroit-Hamtramck plant, the assembly location for the Volt, for use in production validation vehicles.<\/p>\n
Regular production at Brownstown and Detroit-Hamtramck is set to begin in the fourth quarter.<\/p>\n
GM is investing $700 million in eight Michigan facilities for Volt-related production, including $336 million in the Detroit-Hamtramck plant, which will benefit from battery research conducted at the battery lab in Warren; receive batteries from Brownstown; use tooling from Grand Blanc; take delivery of camshafts and connecting rods from Bay City; and dies, stampings and the Volt\u2019s 1.4L engine-generator from three plants in Flint.<\/p>\n
\u201cThe development of electric vehicles like the Chevy Volt is creating entire new sectors in the auto industry \u2013 an \u2018ecosystem\u2019 of battery developers and recyclers, builders of home and commercial charging stations, electric motor suppliers and much more,\u201d Whitacre said. \u201cThese companies and universities are creating new jobs in Michigan and across the U.S. \u2013 green jobs \u2013 and they\u2019re doing it by developing new technology, establishing new manufacturing capability, and strengthening America’s long-term competitiveness.\u201d<\/p>\n
In August, the U.S. Dept. of Energy selected 45 companies, universities and organizations, including GM, in 28 states for more than $2 billion in awards for electric drive and battery manufacturing and transportation electrification. Nearly half of that total is designated for cell, battery and materials manufacturing facilities in Michigan.<\/p>\n
The Volt is an electric vehicle with extended-range capability. It is designed to drive up to 40 miles on electricity without using gasoline or producing tailpipe emissions. When the Volt\u2019s lithium-ion battery is depleted of energy, a flex-fuel engine-generator seamlessly operates to extend the total driving range to about 300 miles before refueling or stopping to recharge the battery. Pricing has not been announced.<\/p>\n
