Euro 7: New Requirements for EV Battery Durability

What Does Euro 7 Mean for Electric Vehicles?

If Euro 7 makes you think primarily of stricter exhaust emission limits, that is only part of the picture. The regulation also covers areas relevant to electric vehicles, including brake particle emissions and traction battery durability. The key Euro 7 requirements will apply to new vehicle types in categories M1 and N1 from 29 November 2026. One year later, from 29 November 2027, they will also apply to all newly registered vehicles in these categories.

This means EV batteries will be subject to binding minimum performance requirements at EU level. These rules apply to both fully electric vehicles and externally rechargeable hybrid vehicles. The key factor is how much usable battery energy remains after a defined period of time or mileage.

What Limits Apply to Euro 7 Battery Durability?

For electric passenger cars in category M1, Euro 7 sets two key thresholds. Up to five years of age or 100,000 kilometres – whichever comes first – the battery must retain at least 80% of the relevant battery energy. After that, a minimum of 72% applies up to eight years or 160,000 kilometres.

The Euro 7 requirements therefore create a consistent framework for battery durability across the EU. Different thresholds apply to light commercial vehicles in category N1: 75% up to five years or 100,000 kilometres, followed by 67% up to eight years or 160,000 kilometres.

Importantly, these rules define regulatory minimum performance requirements and should not automatically be equated with a manufacturer’s battery warranty.

How Are Battery Capacity and Battery Health Assessed?

In everyday discussions, terms such as remaining capacity or State of Health (SoH) are commonly used. Particularly when buying a used EV, this figure can provide useful guidance on the condition of the battery. Euro 7, however, uses more technically precise indicators. One of these is the State of Certified Energy (SOCE), which describes estimated battery performance as a percentage of the usable battery energy.

These values make it easier to understand how a battery ages over time. After all, a traction battery gradually loses some of its performance as it is used. Under Euro 7, the key requirement is that the specified minimum values are met under defined testing and usage conditions. Manufacturers must take these requirements into account as part of the type-approval process, while procedures are also in place to monitor battery durability during real-world operation.

What Do the New Rules Mean for EV Drivers?

If you are considering buying a new or used electric vehicle, battery health will become an increasingly important factor. Transparent information about battery condition can help you assess how much performance a vehicle still has to offer. At the same time, the rules establish a European minimum standard for how far usable battery energy may decline within defined age and mileage limits.

However, this does not mean that every battery will fall to just 72% after 160,000 kilometres or that it will need to be replaced at that point. The figure represents a minimum durability requirement for M1 vehicles. The actual remaining capacity of an individual EV may therefore be significantly higher.

What Euro 7 Means for Charging and E-Mobility

A long-lasting battery and readily available charging infrastructure go hand in hand. While Euro 7 introduces requirements for vehicle technology, public charging options help ensure that electric vehicles remain convenient and flexible to use in everyday life. JOLT focuses on ultra-fast charging in urban areas, bringing charging infrastructure to the places where drivers need it most.

For e-mobility, Euro 7 therefore represents another step towards greater transparency around battery life. If you already drive an EV or are planning to buy one, it will be worth considering battery health and remaining usable energy alongside range and charging power.
