...Wie tief und in welchen Abständen sollte man den Soul entladen um die Kalibrierung optimal durchzuführen (die Angaben von Appel sind da ja nicht unbedingt maßgeblich)..
To calibrate the battery you must charge to 100%, drive down below 10%, and then charge back up to 100%.
My Soul EV is 2 years old. I have been monitoring the battery for about 18 months now.
In that time I have done this calibration 4 times.
I do not usually charge my Soul EV to 100% unless I have to. I have never been below 10%. My car has driven nearly 40,000km and still has SOH 100%. The deterioration counters show I have lost about 9% from the total capacity. Calibration is not really an important issue when the car is still new.
But because I like the technical details.
Specifically the calibration occurs at 392.5 +/-0.1V battery voltage, 4.08V (0xCC) cell voltage and 91.5-92.5% SOC.
The Kia Ray EV is a predecessor to the Soul EV, also with an SK Innovation battery pack. Its range when new is about 100km. I have been renting an old Ray EV for the last few months and have been extensively testing the pack.
In the chart above where I show charging data for the Ray EV the J1772 charges are all from turtle to 100%. The Chademo are all from turtle to the SOC BMS 80% limit. (about 90% real).
I would never do this on my car. I have never driven down to turtle. I try to avoid 100% charges. I avoid Chademo especially in the summer heat. But now I have a rental car I have the chance to do this without worrying. In fact this is probably how rental cars are always used. Looking at the data I would say it doesn't make any difference to do it occasionally.
