General Motors opens its new 33,000 sq-ft Global Battery Systems Lab - the largest automotive battery lab in the United States - Monday, June 8, 2009 at the GM Tech Center in Warren, Michigan. The lab will accelerate the domestic development of advanced battery technology and expedite the introduction of electrically driven vehicles, including the Chevrolet Volt, as well as plug-in hybrids, hybrid-electric vehicles and fuel cell vehicles. GM’s Global Battery Systems lab contains 42 thermal chambers that duplicate extreme real-world driving patterns, hot and cold temperatures and calendar life. (Photo by John F.
