Maybe purchasing a second-hand Leaf and not sure how to read this graph showing the battery health. Is it possible to determine the range from this?

  1. Looks pretty good. Voltages across the cells look balanced and SoH (state of health) shows 90.08%, which really only means a 5-6% loss or range from new, which is on-par with a vehicle of that mileage.

  2. I assume the ‘usable’ capacity is always 90% of the available capacity. Then the only variable is your driving style and needs. Let’s say you get an efficiency of 8km/kWh, then
    Range = battery size * SoH * 0.9 * efficiency
    = 40 * 0.9 * 0.9 * 8 = 259km.

    I have a 30kWh Japanese import to Aus with a SoH of 78%, and driving efficiency of 8.3, which calculates to a range of 175km, which is bang on what the GOM reports.

  3. It’s hard to say without more info, such as model year. But more quick charges than regular charges is never a good sign for a Leaf.

  4. Looks pretty good to me, with SOH at 90%. Will lose its first bar at 85% I think. How old is it/many miles?
