General Motors Battery Lab
GM's Global Battery Systems Lab began operations in January 2009 and became fully operational in May 2009.
It is used by GM's growing team of more than 1,000 engineers working on advanced batteries and electrically driven vehicles. More than half of the current lab is dedicated to testing the electrochemical battery cells and their enclosures, known as modules. The lab's remaining floor space is committed to evaluating completed battery packs.
The recent expansion added capability in six areas, including:
Safety and Abuse Tolerance. Powertrain test cells previously used for engine altitude testing will be retrofitted for crush, penetration, water immersion, overcharge, discharge and short circuit tests
• Buildup and Teardown. Reuse storage areas to prepare batteries before tests and provide secured rooms for supplier evaluation
• Manufacturing Engineering. Reuse space previously occupied by engine dynamometers to improve manufacturing processes, such as laser welding and cell stacking
• Charger Development and Integration
• Thermal Development. Radiant heat, thermal stability and thermal shock testing
• Battery Storage.
