The Automotive Cells Company (ACC) battery joint venture between Stellantis, Mercedes, and TotalEnergies has announced producing its five-millionth cell at its factory in France. The plant's second production block, with a capacity of 12.9 GWh, is set to begin production in 2027.
At the Paris Motor Show, ACC announced that its current cell output at the Douvrin site is enough to equip nearly 40,000 vehicles with its own battery cells. The joint venture also revealed plans to commission the second production block at the plant next year to manufacture batteries for Mercedes-Benz electric vehicles. This will increase the site’s capacity by 12.9 GWh from next year, bringing the total to just under 26 GWh. The final expansion stage currently envisages three production blocks with a combined manufacturing capacity of around 40 GWh.
Automotive Cells Company (ACC) is one of the few European manufacturers of battery cells and modules for electric vehicles. Founded in 2020, the company develops and produces batteries based on NMC chemistry. Its shareholders are Stellantis, Mercedes-Benz, and Saft, a subsidiary of TotalEnergies. ACC currently employs around 2,500 people in France, at its research and development centre and pilot plant in Nouvelle-Aquitaine, and in the Hauts-de-France metropolitan region where its gigafactory in Douvrin is located.
Management emphasises that ACC has “grown significantly and its industrial maturity has evolved considerably” since the last motor show two years ago. The company’s cells and modules are now installed in eight premium electric car models, all marketed by the Stellantis Group. These include the Peugeot E-3008 and E-5008, Jeep Compass, Lancia Gamma, DS N° 7 and N° 8, Citroën C5 Aircross, and the Opel Grandland.
