Progress Reports
General Motors expanded its significant battery research and development capabilities today by opening the largest and most technologically advanced battery lab in the United States on its Technical Center campus in Warren, Michigan.
The new Global Battery Systems Lab will lead GM’s global advanced battery engineering resources and expedite the introduction of electrically driven vehicles, including the Chevrolet Volt, as well as plug-in hybrid and hybrid-electric vehicles and fuel cell vehicles.
“The new global GM battery lab will benefit consumers across America by helping us advance the development of battery technology in the United States and put cleaner, more efficient vehicles on the road more quickly and affordably,” said Fritz Henderson, GM president and CEO. The Global Battery Systems Lab spans 33,000 sq. ft. - four times larger than GM’s previous Tech Center battery lab - and will be used by GM’s growing team of more than 1,000 engineers working on advanced batteries and electrically driven vehicles.
The lab became fully functional in May, equipped with 160 test channels and 42 thermal chambers duplicating extreme real-world driving patterns, hot and cold temperatures and calendar life. The lab’s maximum power capacity is 6 megawatts, or enough electricity to provide power to approximately 1,400 homes.
“More than half of the lab is dedicated to testing the electrochemical battery cells and their enclosures, known as modules, a capability not available in GM’s previous battery lab. The lab’s remaining floor space is committed to evaluating completed battery packs,” said Jim Queen, GM group vice president, Global Engineering.
The Global Battery Systems Lab was built within GM’s Alternative Energy Center facility, and includes many environmentally friendly features such as a center hallway with high-efficiency LED lighting and a floor made from recycled tires. Approximately 90 percent of the electricity used for battery testing can be returned to the local energy grid for use by homeowners and businesses.
Additional new benefits offered include a thermal shaker table for battery structural integrity testing, a battery teardown area for failure analysis and competitor benchmarking, an integrated test automation system and improved Design of Experiments methodology - an information-gathering exercise that allows GM to perform more thorough battery tests more quickly.
The opening of the Global Battery Systems Lab is the latest move in GM’s comprehensive battery strategy, which includes ramping up “in-house” responsibility for advanced battery technology and a broad portfolio of supplier partners.
Energy alternatives and advanced technologies that reduce dependence on petroleum, improve fuel economy and reduce emissions are keys to developing sustainable transportation. GM is pursuing several options to best meet the varied needs of customers around the world - from advanced gasoline, diesel and biofuel technology to electrically assisted vehicles such as hybrids, plug-in hybrids and - ultimately - electrically driven extended-range electric vehicles and hydrogen fuel cell vehicles. GM believes that electrically driven vehicles, based on battery and hydrogen fuel cell technology, offer the best long-term solution for providing sustainable personal transportation.
