A complete record for every electric vehicle in the UK.

One record. Every input. A vehicle’s whole life.
An electric vehicle is only as trustworthy as what you can prove about it. Yet its real story — how the battery has aged, how it has been charged, what work it has had — is scattered across systems that never talk to each other.
The EV Passport brings that story into one place. It is the centralised, independent record of how a vehicle has been treated, combining ClearWatt’s own diagnostics with third-party data so the businesses pricing EV risk can work from evidence instead of assumption.
No inspection requiredEvery passport is assembled from data — no workshop visit and no physical check on the car — so one record or ten thousand take the same effort.
IndependentEvidence drawn from ClearWatt diagnostics and trusted third-party sources, not a seller’s word.
ContinuousA lifetime record that keeps accruing entries — not a single snapshot taken on one day.
Every input, drawn into one record.
Battery health, charging behaviour, servicing and repairs, warranty cover, MOT and mileage, and ownership history — pulled together into a single, comprehensive view of how an electric vehicle has been treated through its life. Powered by ClearWatt.
Built for the businesses that carry EV risk.
The EV Passport is a trade tool. It gives the organisations exposed to a vehicle’s condition a single, defensible source of truth.

Each passport is assembled from ClearWatt’s own measurements and independent records — every input traceable to its source.
Read together, these inputs also establish warranty validity — whether a vehicle’s service history, mileage and battery care still meet the manufacturer’s terms.
