Which part doesnt make sense ?
”Average remaining” range on the Energy app(I use average 50km) use the last 50 kilometers average consumption to calculate the remaning range. Perhaps last 30 miles if using miles. It uses the same calculation method: Remaining kWh divided by the average consumtion(Wh/km or mile) for the last 50km. If used backwars and divided by the remaining percentage of the battery you will get close to the ”Nominal full pack” value. Of course, as the car hides the 4.5% buffer on the last 50% of the battery you should do this with more then 50% in the battery.
Heres one of my tests, landed in Northern Finland with 51%, and the calculation gave me 80.47 kWh battery size. The SMT reported 80.60kWh as ”Nominal full pack” The nominal full was taken just before leaving home. Theres a 0.13kWh delta, but the batteri meter in the var only shows whole percent so it might be a delta of 0.5%.
I have don this calculation about 5-7 times between 51 and 90% SOC and it has not differed more then 0.5kwh, except for the last time( delta= 0.7kwh or roughly 1% of battery size) as shown in the earlier post.
I say this method can be used if you dont have the Scan my testa app + the odb add on and the odb2-bluetooth dongle.
