General Motors has nearly tripled the size of its Global Battery Systems Laboratory, cementing the lab’s stature as the largest battery lab in North America owned and operated by a major auto manufacturer.
The latest addition of 50,000 square feet brings to 85,000 the total square footage of the lab. The expansion made possible the increase in the number of pack-level test channels from 64 to 112 and cell-level test channels from 96 to120.
GM’s Global Battery Systems Lab has been responsible for testing and validating both battery cells and packs for all of GM’s vehicle electrification systems, including the battery systems for the Chevrolet Volt, Cadillac ELR, Chevrolet Spark EV and GM’s eAssist light electrification system.
The expanded lab features dedicated equipment for future vehicle battery system development, building of prototype battery packs for vehicle development programs, and a hub for validation and testing of all future battery systems designed for use in GM vehicles.
GM says the lab will also play a critical role in assuring company’s current generation of electric vehicles maintain their battery leadership position. Teams will validate and test updates to existing chemistries and system designs to make the most of performance and reduce cost. For example, updates were made to the battery system in 2013 Chevrolet Volt that added three miles of EV range.
In addition to the lab in Michigan, GM also operates battery labs in Shanghai, China, and Mainz-Kastel, Germany, which are tasked with testing and validation of battery cells, packs, and advanced battery system development. Teams at the China, Germany and Michigan labs work collectively to test battery systems around the clock to reduce validation time.[wzslider height=”400″ lightbox=”true”]
