General Motors Co. says it will double the size of its suburban Detroit lab that engineers and tests electric vehicle batteries.
The company says the $8 million investment won't create any new jobs, but will allow GM to centralize its battery testing and do tests in-house rather than with outside contractors.
Spokesman Brian Corbett says GM will be able to do safety and abuse tests, manufacturing engineering, charger development and heat tests at the lab.
He says about 1,000 engineers now work on electric vehicle development and the company has 40 to 50 openings.
The expanded lab should open this summer. GM plans to begin selling the rechargeable Chevrolet Volt electric vehicle in December.
