Some data from my side:

Trip 1: 33.5Ah down to 27.2Ah (0.5Ah lost (??) compared to fully charge which was finish 1h30min before start the trip)

Trip 2: 28.4Ah down to 22.3Ah (1.2Ah win while parked for 8h)

Trip 3: 22.3Ah down to 20.8Ah (0 change, but was 10min after 2nd trip end)

While resting in the evening car lost 2.3Ah .. down to 18.5Ah

After the night car lost other 0.3Ah ... down to 18.2Ah

So ... in total +1.2Ah - 2.6Ah ... so car lost 1.4Ah ... while using 13.9Ah

I bet on my next few short trip I need today I will gain 0.1 or 0.2Ah .. so ... ending with ~1.2Ah "lost" ... so ... my battery that is 34Ah per the BMU .. is possibly just 32.7Ah .. with the handicap that I can't use the top 0.5Ah .. since the charging process end too fast, (or immediately after charge car lose 0.5Ah) .... so .... it is more like a 32.2Ah ... that is just 85% SOH real

Next day ... after Trip 4 and rest ... down to 15.4Ah ... so further 0.4Ah lost

So .. initial win 1.2Ah

Later ... Total lost : 3Ah

Balance : Lost 1.8Ah .. used ... 16.3Ah ... over 10% waste while "parked"
