Trust is the missing part of the used-EV market. We're building it.

Battery condition is to an electric car what engine condition was to petrol and diesel — invisible, worth thousands, and until now unverifiable by ordinary buyers.

Mission

Make every EV battery's condition visible

Independent, evidence-based battery health for buyers, dealers and fleets — read from the vehicle itself, affordable to anyone, explained in plain English.

Purpose

Independence over opinion

We work for the person reading the report, never the seller. One vehicle, one dataset, one honest verdict — tied to the registration number for anyone to verify.

Goals

Where we're headed

  • Certificates for the UK's most-bought used EVs, starting with the Leaf
  • Live dongle-to-website readings (manual CSV upload today)
  • Dealer & fleet subscriptions, API-embedded reports
  • Valuation, predictive maintenance, insurer integrations
