Most people assume Porsche’s retreat from in-house battery cell manufacturing means the brand is stepping back from electric vehicles altogether. That’s not what happened, and treating it that way misses the real story. The porsche ev battery plans change announced in late August 2025 is about who builds the cells, not whether Porsche keeps building EVs.

Porsche is no longer pursuing its own production of battery cells at scale. The company said the economics simply did not work at the volumes it could realistically sell. Its battery unit, Cellforce, is shifting from manufacturing toward research instead.

That distinction matters for anyone shopping a Taycan, watching Porsche’s stock, or trying to understand where the EV battery business is headed. Porsche has cancelled plans for its own gigawatt-scale factory, not its electric lineup.

The Mistake Most Coverage Makes

The common error is reading this as a retreat from electrification. It is really a retreat from vertical integration, which is a much narrower and more specific decision. Porsche still sells EVs, still has more coming, and still needs batteries from somewhere.

Here’s the corrected version: Porsche looked at how many cells it could actually use each year, compared that to the billions required to build a competitive battery production line, and concluded the math didn’t close. CEO Oliver Blume put it plainly, saying Porsche is no longer pursuing its own production of battery cells “for volume reasons and a lack of economies of scale.”

That’s a manufacturing decision, not an ideological one. Porsche isn’t backing away from selling electric cars.

What Actually Happened

In August 2025, Porsche confirmed that its battery cell subsidiary, Cellforce, would scale down and pivot toward cell research and development rather than mass production. The unit had built a pilot line in southern Germany and was working toward a factory capable of producing about one gigawatt-hour of cells annually, enough for roughly 10,000 Taycan-sized battery packs a year.

A second, larger plant was meant to follow that first one. None of that expansion is happening now.

Key facts from the announcement:

• Porsche will not build its own battery cell manufacturing capacity at scale.
• Cellforce shifts to research and development instead of production.
• Roughly two-thirds of Cellforce’s near-300 staff are being let go.
• Remaining staff may move to Volkswagen Group’s battery arm, PowerCo.
• The R&D work will support both PowerCo and V4Smart, a high-performance battery company Porsche acquired this year that already supplies cells for the 911 GTS hybrid.

Michael Steiner, the Porsche board member overseeing research and development, said the market had not developed the way the company expected when it launched Cellforce back in 2021. Back then, Blume had called the battery cell “the combustion chamber of the future,” a line that now reads as more optimistic than accurate.

Why the Numbers Stopped Adding Up

Building battery cells at competitive cost requires enormous scale. Billions of dollars go into a plant before a single usable cell rolls off the line, and the cost per cell only drops once volume climbs into the hundreds of thousands or millions of units a year.

Porsche never had that volume, and it was never going to get there quickly. The brand sells around 300,000 vehicles a year worldwide across its whole lineup, EVs and combustion cars combined. That’s a fraction of what dedicated battery makers produce annually for the entire industry.

Several forces pushed this outcome:

• Slower-than-expected EV demand in the US and China, Porsche’s two largest markets.
• The rollback of US fuel economy rules and the winding down of EV tax credits.
• A broader pullback in clean energy policy support under the current US administration.
• Rising competition from Chinese and Korean cell suppliers already operating at scale.

Slow demand forces Porsche to accept that a niche automaker cannot out-invest global cell giants. Steiner said the company had to conclude the planned business model “is not economically viable,” language that leaves little room for reinterpretation.

What Happens to the Cellforce Team

Cellforce employed close to 300 people before this shift. Roughly 200 of those roles are being eliminated, based on information from a person familiar with the matter.

The remaining staff, along with the Cellforce site itself, will pivot toward high-performance cell research rather than manufacturing. That work will feed two places:

• Volkswagen Group’s battery subsidiary, PowerCo, which is building large-scale plants elsewhere.
• V4Smart, the smaller performance-battery maker Porsche picked up this year.

It’s a smaller, quieter operation than what was originally planned, but it isn’t a full shutdown. Porsche is preserving the engineering knowledge while cutting the expensive part: the factory floor.

Where Porsche’s Cells Will Come From Now

With in-house production off the table, Porsche keeps relying on established outside suppliers. The Macan Electric uses cells from Contemporary Amperex Technology Co. Limited, better known as CATL, the Chinese battery maker that leads the global market by a wide margin. The Taycan uses cells supplied by LG Energy Solution.

That arrangement isn’t new. It’s simply staying in place instead of being replaced by home-grown cells down the line.

Porsche still has several electric models in the pipeline that will need batteries sourced the same way:

• An electric Cayenne, expected in the next couple of years.
• A future all-electric sports car in the 718 family.
• Continued Taycan and Macan Electric production using existing supply deals.

None of that changes because Cellforce stepped back. The vehicles arrive on schedule; only the cell sourcing stays external.

The Bigger Pattern Across the Battery Business

Porsche’s decision fits a wider trend playing out across the industry. Building an independent battery supply chain from scratch has proven brutally hard, even for companies with deep pockets.

Northvolt, once seen as Europe’s best hope for a homegrown battery tech rival to Chinese and Korean suppliers, filed for bankruptcy in the US last year after burning through billions without reaching the scale it needed. Porsche’s much smaller Cellforce bet was always more modest than Northvolt’s, but the underlying problem was the same: scale beats ambition in this business.

Meanwhile, the biggest players keep consolidating share. CATL, BYD, and LG Energy Solution are absorbing more of the global market, while smaller in-house efforts get shelved one by one. LG Energy Solution, for its part, has been leaning harder into grid-scale storage as EV sales growth stays uneven across regions.

The Volkswagen Group hasn’t abandoned battery ambitions altogether, though. It continues investing in raw material sourcing, next-generation solid-state cell research, and three large battery plants slated for Spain, Germany, and Canada through PowerCo. The group is betting on scale at the parent-company level instead of letting each brand chase its own factory.

What This Means for Buyers and the Wider EV Market

For someone shopping a car today, none of this changes what’s on the lot. Existing EVs keep their current battery suppliers, and warranty coverage and service support remain unaffected.

Porsche’s broader EV momentum hasn’t stalled either. EVs and hybrids made up 36% of Porsche’s global deliveries in the first half of 2025, and Taycan sales in the US rose 31% year over year in the second quarter. The electric vehicle side of the business is still growing, just not fast enough to justify a captive cell factory.

A few practical takeaways for readers following this space:

• Battery sourcing decisions rarely affect the vehicles already sold or under warranty.
• Watch for supplier announcements rather than assuming a company’s own factory news changes anything about current models.
• Smaller automakers attempting in-house cell production face the steepest odds; scale is the deciding factor, not ambition or engineering talent.
• Expect more consolidation among battery makers, with fewer, larger suppliers dominating the next several years.

SBM’s view here is straightforward: relying on a handful of giant cell suppliers concentrates risk and leverage in too few hands, and that’s not a healthy long-term setup for automakers or buyers. Automakers pooling resources through groups like PowerCo, rather than each chasing its own factory, is the more sensible path forward, even if it means less brand-level independence.

Frequently Asked Questions

Why did Porsche cancel its own battery cell production plans?

Porsche said the volumes it could realistically sell didn’t justify the billions needed to build a competitive cell factory. Slower EV demand in the US and China made the original business case fall apart.

Does this affect the Taycan or Macan Electric I already own?

No. Existing vehicles keep their current battery suppliers, LG Energy Solution for the Taycan and CATL for the Macan Electric, with no change to warranty or service.

What happens to the Cellforce factory and staff?

The site shifts from manufacturing toward battery research and development. Around two-thirds of the roughly 300 staff are being let go, while some may move into roles at Volkswagen Group’s PowerCo battery unit.

Is Porsche giving up on electric vehicles?

No. Porsche still has an electric Cayenne and a future electric 718 sports car planned, and EVs plus hybrids already make up more than a third of its global sales.

Who supplies Porsche’s batteries now that Cellforce is scaling back?

CATL supplies cells for the Macan Electric, and LG Energy Solution supplies cells for the Taycan. Porsche will keep buying from established suppliers rather than building its own cells.

Is this part of a wider trend among automakers?

Yes. Smaller in-house battery efforts, including Northvolt’s larger and separate collapse, keep losing out to a handful of dominant global cell makers with far greater scale.

Next Step

Anyone tracking Porsche’s electric lineup should watch for updates from PowerCo and V4Smart rather than Cellforce itself, since that’s where the actual cell development work is headed next.
