EV batteries · Reviewed 30 September 2026
EV traction batteries are in scope by category.
There is no capacity threshold for electric-vehicle batteries. If it is a traction battery placed on the market or put into service from 18 Feb 2027, it needs a passport — the 2 kWh figure people quote belongs to the industrial category.
What counts, and who carries the obligation
Article 77 names electric-vehicle batteries as a category in scope, alongside LMT batteries and industrial batteries over 2 kWh. The threshold qualifies the industrial category only.
The obligation falls on the economic operator placing the finished battery on the market — often an importer or vehicle manufacturer rather than whoever produced the cells.
The passport is not the hard part
A traction battery spends years in service before anybody asks it a hard question. What makes that question answerable is a record of what the pack reported over those years — charge and discharge, temperature, cycles, faults — with its source and its gaps visible.
That record cannot be assembled retrospectively for a period nothing was collected in, which is why the work starts before the deadline rather than at it.
Resale and second life
An EV pack leaving its first application is worth what somebody will pay for a claim about its condition. A state-of-health figure on a screen is a number; the history behind it — how it was charged, how hot it ran, how often it was cycled and where the data stops — is what an assessor can act on.
Adaptr keeps the observations and shows where the record has gaps rather than interpolating over them. It does not certify a pack for second-life use: that needs independent assessment.

A practical first step
Bring one pack and the claim you need to stand behind.
We will look at what your hardware already reports and whether it is enough to evidence a health claim, and say so if it is not.
