Euro 7 battery durability rules: what Europe's new standard demands from EV batteries
From 29 November 2026, new car and van models approved in the EU must meet Euro 7, the first European standard to set a legal floor for how well an EV battery holds up. What the regulation says, when it applies to every new car, and what it means for used EV buyers.
For most drivers, the "Euro" emission standards have always been about the exhaust pipe. Euro 7 changes that. The European regulation that starts applying to new car and van models on 29 November 2026 contains, for the first time, a full chapter on the batteries of electric and plug-in hybrid cars. In short, the law sets how much a battery is allowed to wear in its first years, and it requires the car to report its condition honestly.
The topic is back in the news this week because the United Kingdom has confirmed it will adopt the same rules, and on 4 November European Parliament committees voted on changes to the EU's automotive package that also touch Euro 7.
What the regulation actually says
The legal text is Regulation (EU) 2024/1257, available on EUR-Lex. Its annex on battery durability sets two minimum capacity thresholds for passenger cars (category M1):
- for the first 5 years or 100,000 km, whichever comes first, the battery must keep at least 80% of its original energy;
- beyond that point and up to 8 years or 160,000 km, the floor drops to 72%.
The rule covers both fully electric cars and plug-in hybrids. Light vans (N1) have a separate table with their own values.
The second key element is the battery health monitor, the "state of health" (SOH) reading. Euro 7 requires it to be fitted, accurate, accessible and comparable across brands. In its official consultation response, the UK government spells out the reason: people buying a used EV should get standardised information about the battery, not just reassurances.
Two dates to remember
For cars and light vans the regulation has two steps:
- 29 November 2026: EU authorities will refuse type approval for new vehicle types that do not meet Euro 7, battery durability included.
- 29 November 2027: the rule extends to every new vehicle registered. From then on, a non-compliant new car can no longer be sold or registered in the EU.
Small-volume manufacturers have until 1 July 2030. Trucks and buses follow a separate timetable starting in 2028.
What happened this week
On 4 November, three European Parliament committees adopted their position on the so-called "automotive omnibus" by 105 votes to 39, with 21 abstentions. Among the proposals: an 18-month delay of Euro 7 requirements for trucks and buses, and a new category of small EU-made electric cars up to 4.2 metres long. The car deadlines above are not moved by this text. It is not final yet: the plenary vote is expected in December, followed by talks with member states.
Separately, the UK has decided to adopt Euro 7 by accepting EU and UN type approvals directly, so carmakers will not need separate British testing. The key date there is also 29 November 2027 for all new cars.
What the rules do not cover
Euro 7 is not retroactive. Cars already on the road, and those approved under older rules before the 2027 deadline, do not suddenly gain this protection. The legal floor also does not replace the manufacturer's commercial battery warranty, which may be more generous or worded differently. The regulation also brings limits for brake particles and, from 1 July 2028, for car tyre wear, which apply to every car, electric ones included.
What it means for drivers
If you buy a new EV in 2027 or 2028, it is worth asking whether the model is Euro 7 approved. That gives you a legal minimum for battery capacity and a health reading you can check at any time.
The biggest change will come in the used market. In a few years, when you shop for a second-hand EV, you should be able to see the SOH figure straight from the car, in a format you can compare across brands. Until then, checking the battery of today's cars is still up to you, and our guide to checking a used EV's battery health walks you through it.
One practical note: 80% after five years is a legal minimum, not a target. Most modern EVs that are looked after reasonably degrade less than that. But if a battery does drop below the threshold within the covered period, the regulation gives the owner a strong argument when dealing with the manufacturer.
