About this app

ClearWatt empowers electric vehicle buyers, sellers and owners to independently test and certify the battery health of any electric vehicle. Backed by the Department for Transport in the UK, ClearWatt is on a mission to improve information and data available to consumers purchasing and selling second-hand electric vehicles.

Requiring no hardware, our app is powered by advanced machine vision, connected car technology and cutting-edge mobile telematics. Our technology allows you to independently appraise your electric vehicle’s performance, whether you are buying, selling or already own the car.

Testing with ClearWatt is simple: register your vehicle, drive with our app running in the background and pay to unlock your unique EV Health Report containing comprehensive insights on battery degradation, real-world driving range, charging, wheel performance, MOT data and more!
