GM is closing its Detroit EV battery plant

General Motors is shutting down its 480,000-square-foot Brownstown Battery Assembly plant in Detroit, which supplied high-voltage batteries for the Cadillac Celestiq and Chevrolet Corvette E-Ray. The facility, opened in 2009, will be decommissioned by next summer when its lease ends as GM shifts focus to gas vehicles.

• Plant built packs for Celestiq and Corvette E-Ray
• Headcount fell from ~300 to fewer than a dozen
• Q3 US EV sales dropped to 25,472 from 66,501
• GM already exited Samsung SDI JV and Lansing plant
