From 2027, the European Union will require a digital record for the large batteries sold inside electric cars.
A battery passport is the mandatory digital record the EU will require starting in 2027 for large electric vehicle batteries, logging details like the materials used, the battery's carbon footprint, and its ongoing health over its lifetime. This transparency is meant to support repair, reuse, and recycling decisions, helping build a stronger circular economy for the valuable and often scarce minerals inside EV batteries.
A carbon receipt is not an established regulatory term and doesn't describe this specific EU requirement. A mileage stamp similarly isn't a real mandated record and doesn't capture the detailed material and health tracking the battery passport actually requires.
By tracking a battery from manufacture through its entire life, a battery passport could make it much easier to determine whether an aging EV battery still has useful life left in a less demanding second application, such as stationary home energy storage, before it is finally recycled.
