Until now the European car industry's objection to the EU's battery localisation rules has been a warning: Europe cannot build cells fast enough. On 30 September 2026 it became a counter-proposal with dates attached.
Sigrid de Vries, director general of ACEA, published the ask in a message titled "Building in Europe takes time. Batteries included." It is the first time the lobby has said how much later it wants the Industrial Accelerator Act's requirements to bite.
What is on the table
| Requirement | The Act as drafted | What ACEA asks for |
|---|---|---|
| Three EU-origin battery components, including cells | Six months after adoption | Three years after adoption |
| Five components, adding battery management systems and cathode active material | Three years later | Five years |
| Trucks and buses | Same timetable as cars | Separate treatment |
"We are asking for that to move to three years after adoption for the first requirement and five years for the second, with separate treatment for trucks and buses, where no credible timeline exists today," de Vries wrote.
The heavy-duty carve-out has the least wriggle room in it. ACEA's own truck study, published on 25 September, argues that mandatory EU-origin battery components should apply only once supply has been confirmed — and that such supply is unlikely before 2035.
The argument is about construction time, not willingness
ACEA does not dispute that Europe should build cells. It disputes the clock. "From announcement to full production, a new battery plant can take close to a decade," de Vries wrote — which is why a requirement landing six months after adoption asks for capacity that was either commissioned years ago or does not exist.
The second strand is that a cell plant is not the whole supply chain. "Two-thirds of the value in battery cell supply chains sits upstream: in raw materials, mining, refining, and components," she wrote. Localising the final step leaves the majority of the value, and the dependency, where it already is.
The price tag belongs to someone else
The affordability number in the message is not ACEA's own, and the attribution matters. It comes from Bruegel, the Brussels economic think tank, whose policy brief argues against exactly the protection the Act proposes: sourcing EU-produced cells "could raise costs by €2,100 per battery electric car."
The arithmetic is simple enough to check. Bruegel assumes a binding EU-origin rule takes cell costs from about €50 per kWh to about €85, and applies the €35 difference to a 60 kWh pack, the average for a new battery-electric car. That is where €2,100 comes from, and it is a modelled figure rather than a quoted price.
Not everyone reads the supply picture this way
ACEA's timetable rests on its commissioned finding that around three million cars would fail to qualify if the Act starts in 2028. Transport & Environment published the opposite conclusion a day later, arguing that Europe will have enough locally made cells by 2030 to cover every car the rules actually touch. Both are forecasts, and both commissioners have an interest in the answer.
What it means for a European Tesla buyer
Tesla is one of very few volume manufacturers with cells already scheduled inside the EU: 4680 production at Grünheide from 2027, at up to 18 GWh a year. On a six-month trigger that timing is an advantage; on ACEA's three-year version it stops being one, because everyone else gets time to catch up.
Nothing is settled. The Act is a proposal, the Parliament's transport committee has already pushed its vote on the wider auto package back by about two weeks, and the thresholds can move. What has changed is that the industry is no longer only objecting — it has tabled a schedule, and Brussels has to answer it.
