Yesterday I had the opportunity to test a brand new HPC charging station Enel X has installed in Rome some 5 km from my home. It's made of 4 Tritium 350kw charger so it's very like a Ionity station. I arrived with 20% Soc (I know, I should got there with a lower SOC for a more extended test) and charged up to 91% with a MY21. Ambient temperature 20°C, initial battery temperature around 31°C. Following are the data coming from charger display and from OBD2 (l started logging not from the beginning of the charge so a little part of the initial chargin session is missing from OBD2 data).
OBD2 data
Charger data
In this last graph I also added manually the most common chargin curve for MY19/20. I know that sometime it could better than that but at least in my experience that is the most common curving charge I experienced at Ionity stations.
As Tesla Bjorn reported already in a video, the MY21 initial charging curve is faster (his was a little bit worse I guess due much lower temprature in Norway ) up to 40%. Thne 40 - 45% the curves are the same but from there onwards the MY19/20 is alwyaws faster. Not a lot faster but it is noticeably faster. As you can see the MY21 has fixed current steps that are limiting the charging speed while MY19/20 are more gradual in the max power shaping.
That being said, it's very nice to see a peak of 110kw, finally :mrgreen:
Total charging time I guess it's not going to be much different at least if pushing the MY21 above 80% SoC. I also guess that when using 50kw chargers MY19/20 will be faster as MY21 drops below "full 50kw speed" earlier and consistently.
