Automotive Cells Company (ACC) is a joint venture created in the summer of 2020, supported by Stellantis, Mercedes-Benz, and Saft (a subsidiary of TotalEnergies). Our ambition is to produce electric batteries at the highest technological level while developing cleaner and more accessible mobility for all.
We are proud to manufacture, in our Billy-Berclau Gigafactory, the batteries that already power several electric vehicles available on the market (PEUGEOT E-3008 and E-5008, Opel Grandland, DS N°8, Citroën C5 AirCross, and Jeep Compass).
Since 2023, Block 1 of our Billy-Berclau / Douvrin Gigafactory has entered production. This first block marks a decisive milestone in the site’s history: after the launch of the first production lines, we are now engaged in a ramp-up phase—an essential step toward reaching full industrial capacity.
This period is marked by major technical and human challenges: ensuring process reliability, optimizing performance, strengthening skills, and embedding a culture of operational excellence.
To support this industrial acceleration, we are recruiting dynamic and passionate teams across Production, Maintenance, Quality, Engineering, HSES, and Logistics.
- ️ Joining Block 1 means taking part in the very heart of ACC’s industrial development and contributing every day to the success of our Gigafactory.
Join ACC and be part of shaping the future of electric mobility. Our batteries already power the PEUGEOT E-3008 and E-5008, Opel Grandland, DS N°8, Citroën C5 Aircross and Jeep Compass — and soon, Mercedes!
