I have a 100D (Dec 18 build). Weekly, I make the same nearly 100 mile trip with no stops and I always charge at home prior to leaving. Typically, at the end of the trip, the trip chart on the dash display shows ~25kWh since last charge, depending on weather conditions, traffic, etc. The %SOC of battery “used” (subtracting arrival SOC from departure SOC) is generally ~30%. So the kWh used is always less than the % battery SOC depletion. Assuming a usable 95 kWh, 30% depletion would be 28.5kWh. I am curious why there is a difference? Perhaps the algorithm the kWh uses in the trip chart differs from SOC algorithm. In any event, the the SOC used is alway greater than the kWh used. Practically speaking it doesn’t really matter but I would like to understand this. Any thoughts?
