My Performance 2021 start to worrie me.
Started at 79,6 continued to be 79,6 ...went to 79,7 - 79,8 -79,9 then decreased to 79,6 again.
Charged to 100% went to 80,1 kWh and just the time to be at 90% 20 minutes later, and it was again 79,6 . Here in Italy we are at 20°C during the day.
Today it is 79,5kWh
It seems like eivissa is right on the theory of triggering a higher NFP(Nominal Full Pack) value by using a lower charge level.
I use a lower value, because I both can ( have my own WC and daily drives at weekdays about 100km) and have some knowledge about how to preserve lithium batteries so I decided to use that as the base.
My NFP increased from a steady 80.1 kwh during two months of higher SOC to 81.4 kWh and this was probably connected to my lowering of the charging level to 56%.
Some days ago I charged to 85% because of two 100 drives the same day. It wouldnt Actually take 85% to do the trips but my wife would do the later on and to avoid any range anxiety I charged more.
That morning with 86% the NFP was down to 80.9kWh. After the drives I saw 81.1, and as I reset the daily charge to 56% the value climbed back to 81.4kWh again after three days.
I guess that the NFP value is quite dependant on the charging level and that we would see much more similar values If we all had the same charging schedule.
I guess that its no need to worry if you see smaller values than someone else as early as we are today with the 82kWh pack/2170L-cells. Also, I guess that its not a very high probability to get a battery that actually is worse( the probability to get 4416 cells that have an average capacity lower than normal is very small).
