1. What to expect

First and foremost, thank you for helping us test the BETA version of ClearWatt’s mobile app. This app is not the final version of our product, it may do some strange and frustrating things at times. This is normal and we appreciate your patience. We’d like you to record every journey over 15 miles in your EV with ClearWatt. You can expect roughly the following process:
1. Sign up/ sign in
2. Car registration via your number plate
3. Driving with the app running in the background
4. Complete 3 drives (each more than 15 miles) - whenever, wherever. Please make sure you’re returned back to the homepage after completing a drive to ensure your data is safely submitted
5. Look at the results you’re issued after 3 drives and let us know how these compare to your experience with this vehicle
6. Jump back to Step 2 and add your car again to repeat the process Even after you’ve been issued your results for the first time, we’d like you to carry on using our app.
Once you receive your results for the first time, we’re hoping you can provide us with some preliminary feedback on the accuracy of those results relative to your experience with the car. We don’t care if they’re slightly off the mark, just let us know by Whatsapp, in-app forms, email, text or pick up the phone, whatever you prefer!

    How does the grading system work?

    Cars are graded by ClearWatt's proprietary grading algorithm. This algorithm leverages benchmark data to grade vehicles based on their performance relative to when they were brand new and relative to other cars with a similar age. When the vehicle is young, our grading algorithm prioritises performance relative to brand new. As the vehicle ages, the algorithm prioritises grading based on the peformance relative to its peers.
    Our grades span from A+ (excellent condition) to D (poor condition).

    What is the ClearWatt Average Range Estimate?

    The range estimate is the range we believe your car will achieve under a set of normalised conditions. This is the range that the vehicle will achieve on a mild & calm day whilst driving on mostly flat roads. We show the range as two values: a minimum and a maximum to demonstrate the difference between motorway and urban driving.
