Porsche’s High-Voltage Plan Loses Power as Cellforce Shifts to R&D

• Porsche scraps Cellforce battery production plans, citing lack of economies of scale and slower EV demand in Europe.

• The Cellforce Group will pivot to research and development, focusing on high-performance battery cells and system innovation.

• Volkswagen’s PowerCo and suppliers like V4Smart will absorb parts of the project as Porsche realigns its global EV strategy.

Porsche confirmed that its Cellforce Group will suspend plans to mass-produce high-performance battery cells, instead deciding to rebalance the unit as an independent R&D center. The decision highlights how even premium automakers struggle with the economies of scale in cell production, particularly in the face of a European EV slowdown in demand relative to the accelerating ramp-up in China and the U.S.

For Porsche, the choice will put its highly-hyped 1 GWh "start-up factory" in Kirchentellinsfurt, Baden-Württemberg, on hold, with opening expected in the middle of the decade. Cellforce, instead, will have a pilot production line for know-how transfer, concentrating on battery system development, future-generation chemistries, and performance-oriented research.

Why the turnaround?

Porsche board member Michael Steiner was frank: planned volumes just weren't high enough to make a very expensive in-house cell factory worthwhile. On a practical level, scaling issues and economics precluded the Cellforce proposal. Market realities are running up against Europe's dreams of hosting local gigafactories, industry analysts argue, referencing Northvolt's failure earlier this year.

The company also emphasized that Volkswagen's PowerCo — and suppliers such as V4Smart, the old Varta performance cell business — will take on some of the jobs and continue to drive Porsche's electrification strategy.

Influence on Porsche's EV strategy

This reorganization will not sidetrack future models like the Taycan, Macan Electric, and 718 electric sports car, which will still be dependent on supplier partnerships. Porsche's global electrification rate reached approximately 57% in Europe and 36% globally in the first half of 2025, reflecting healthy demand but revealing how much of its volume remains dependent on third-party cell providers.

The firm insists the Cellforce R&D emphasis will enhance Porsche's position in high-performance use, from motorsport initiatives to sophisticated "booster cell" technology associated with its core products such as the 911 GTS hybrid.

The bigger picture

By suspending Cellforce production, Porsche is sending a message that scale is the purview of mass-market players, and niche performance players will have to increasingly outsource cell supply and focus on research and differentiation. China and the U.S. are racing forward with EV adoption, and Europe's battery ecosystem is at a turning point: innovate quickly or get left behind.
