More than 100 employees at the Mirafiori Battery Technology Center, most of them upskilled Stellantis workers, will perform and oversee climatic stress tests, lifespan durability testing, battery management system (BMS) software development and calibration, and tear downs of packs and cells for analysis and benchmarking.
The Mirafiori Battery Technology Center covers 8,000 square meters (86,111 square feet), spread over three levels. The heart of the center is 32 climatic test chambers – 24 walk-in chambers for testing battery packs and eight chambers for testing cells.
The climate in the 24 walk-in chambers can be controlled for humidity and temperature, with a range from -40 to 60 degrees Celsius (-40 to 140 degrees Fahrenheit) and a maximum change of 20 degrees per minute. The center can test up to 47 battery packs in parallel.
Designed for future growth, the technology center’s power system can manage up to 1.2 kilovolts (kV) and 2.2 megawatts (MW) per test cell.
The eight cell chambers are capable of testing 96 cells in parallel. This part of the technology center will be devoted mainly to screening innovative battery chemistry and cell behavior characterization for future development.
Stellantis is also building a Battery Technology Center for North America, in Windsor, Ontario, Canada, as part of a global battery development and manufacturing network that will include six gigafactories.
