Porsche drops in-house EV battery production as demand slows

Porsche shifts battery plans

Porsche says it will no longer pursue in-house cell manufacturing and will refocus its Cellforce unit on battery cell and system R&D. CEO Oliver Blume cited ‘volume reasons’ and a lack of scale for ending its own-cell production, making in-house manufacturing uneconomical.

Porsche described Cellforce as a “start-up factory,” but the business never reached the scale needed to compete with giants like CATL and LG. By shutting down production plans, the brand can focus resources on technology and innovation rather than pouring billions into manufacturing capacity it cannot sustain profitably.

Cellforce faces major cuts

The change has direct consequences for Cellforce’s workforce. About 200 of the nearly 300 employees are expected to lose their jobs.

Porsche noted that some employees may transfer to Volkswagen-owned PowerCo, which will also use Cellforce’s research center. This restructuring reflects the harsh realities faced by even major automakers in the challenging EV battery sector.

Why Porsche hit pause

According to Reuters, Michael Steiner, Porsche’s research chief, said global EV demand hasn’t expanded as quickly as once believed. He admitted that the company’s planned business model for large-scale battery production was “not economically viable.”

Steiner explained that slower adoption, especially in the U.S., forced Porsche to adjust. With changing policies and fewer incentives, the company could not justify expanding its own high-performance battery production

The EV market slowdown

Porsche is not alone: Mercedes-Benz delayed electrification targets and paused some U.S. EQ deliveries; Ford has delayed multiple EV launches; Honda has shifted emphasis toward hybrids and trimmed near-term EV investment.

Weaker U.S. demand alongside 2025 policy changes, ending federal EV purchase credits on Sept. 30 and rolling back prior EV targets and fuel-economy enforcement, have also weighed on plans.

China’s market dominance

China continues to dominate the global EV battery industry through companies like CATL and BYD. These firms benefit from mature supply chains and massive scale, letting them produce cheaper, high-quality cells.

Western automakers, including Porsche, struggle to compete against such cost advantages. For many, partnerships with Chinese suppliers are the only realistic way forward to secure battery supply.

European struggles continue

Europe once hoped to create its own battery champions. Swedish company Northvolt was considered a leader but ultimately filed for bankruptcy last year after failing to achieve scale.

Northvolt’s collapse highlights how challenging the economics of battery production are for smaller players. Without size, investment, and steady demand, these ventures cannot keep pace with established Asian rivals.

Porsche EV sales grow

The Porsche Taycan sedan is also performing strongly in the U.S auto market. Porsche reported sales grew 31% year-over-year in the second quarter of 2025.

That rise saw deliveries climb from 807 units to 1,064. The growth signals steady enthusiasm for Porsche’s high-performance EVs, even in a softer overall market.

Cellforce’s early ambitions

Cellforce once had big dreams for its factory in Germany. Cellforce’s Kirchentellinsfurt site was conceived as a 1 GWh ‘start-up factory,’ with later expansion envisioned.

The plan included a second, larger facility once EV demand grew. But slower adoption worldwide forced Porsche to shelve this expansion before it began.

New EV models coming

Porsche has no intention of abandoning electrification. According to Porsche Newsroom, CEO Oliver Blume said, “Electromobility will remain an essential drive technology for our sports cars in the future.”

Upcoming models include an all-electric Cayenne and a new 718 sports car family. These launches show Porsche’s strategy is to grow its EV lineup while refining technology.

What happens next

According to Reuters, Porsche says Cellforce will now fully pivot to research instead of production. The division will provide technical expertise to both the Volkswagen Group and V4Smart, a battery company Porsche acquired this year.

V4Smart already supplies high-performance cells for the new 911 GTS hybrid sports car, which strengthens Porsche’s EV credibility.

This transition ensures Porsche remains active in advanced cell development while sidestepping costly mass production, keeping specialized knowledge within its network and supporting the broader Volkswagen battery ecosystem.

CATL’s role with Porsche

Industry reporting indicates CATL supplies cells for the Macan Electric, while LG Energy Solution’s cells are used in Taycan packs.

This approach allows Porsche to benefit from proven suppliers without committing billions to its own production. It secures access to advanced technology, ensures reliable availability, and frees Porsche to concentrate resources on performance, innovation, and expanding its EV portfolio.

The brutal economics

Producing EV batteries requires billions of dollars upfront and long-term scale to remain profitable. Smaller ventures like Porsche’s Cellforce couldn’t sustain themselves against massive competitors.

The market is consolidating rapidly around global leaders such as CATL, BYD, and LG Energy Solution, whose size provides unmatched advantages. Niche projects, no matter how advanced technically, cannot match the economies of scale and are being forced to exit or adapt.

U.S. market pressures

U.S. EV adoption has been pressured by 2025 policy reversals: the $7,500/$4,000 purchase credits end Sept. 30, 2025; the 2030 EV sales target was revoked; and enforcement of fuel-economy penalties since MY2022 was eliminated, changes that collectively soften incentives.

These changes affect automakers like Porsche, which counted on regulatory support to accelerate electrification. As a result, gasoline-powered vehicles are expected to remain in Porsche’s lineup longer than planned, shaping how fast the company can transition toward all-electric offerings.

EVs still core for Porsche

Porsche’s retreat from battery manufacturing doesn’t signal a retreat from electrification. The company remains committed to building sports cars that use electric drivetrains for performance and efficiency.

According to Porsche Newsroom, CEO Oliver Blume emphasized that Porsche will keep expanding its EV portfolio, including upcoming electric versions of the Cayenne and 718. Strong execution, the company believes, will guarantee it secures the long-term resources necessary for success.
