About Automotive Cells Company (ACC)

Automotive Cells Company (ACC) is a joint venture established in the summer of 2020 and supported by Stellantis, Mercedes-Benz, and Saft (a subsidiary of TotalEnergies). Our ambition is to produce electric batteries at the highest technological level while promoting cleaner and more accessible mobility for everyone.

🔋 At our Gigafactory in Billy-Berclau, we are proud to manufacture the batteries that already power several electric vehicles available on the market, including the PEUGEOT E-3008 and E-5008, Opel Grandland, DS N°8, Citroën C5 AirCross and Jeep Compass.

Our Billy-Berclau / Douvrin Gigafactory is now entering a new phase: the launch of its second production block.
This is a key milestone for the site — new lines, new equipment, new teams… and new challenges to take on as we move toward full production capacity.

To bring this ambition to life, we are looking for skilled and agile professionals across all areas essential to a plant’s operation: Production, Maintenance, Quality, Engineering, HSES, and more — to join our Gigafactory in Billy-Berclau (Hauts-de-France), our Industrial Excellence Center in Nersac (Angoulême), and our R&D Center in Bruges (Bordeaux).
