Dear,

I have the following issue ( 2018 Model S 100D)

when charging my car to 100% it quickly drops to 80%.

After only 6-7kwh according to the trip-meter it already shows 80%.

I always thought degradation is evenly spread but it seems it’s more at the higher SOC than lower ? Is that correct ?

pcan charge around 83kwh ( from 0%-100% )

I have driven around 110.000 km.
Is this “normal” ?

kind regards
NICK

your post doesnt really make any sense because you seem to be confusing concepts.
whats your wh/km and distance you have driven?

Degradation can be observed by looking at your rated kms at i.e. 90% or 100%.

83 kwh from 0 to 100% sounds probably ok for a 110k kms - im a assume you have around 10-15% degradation so 83kwh + 4-5kwh buffer + some heat loss sounds about right.
