Checked two Dutch I-Pace's that show 14.2 as well and nothing for BMS/battery. What is odd/interesting is that I've now tried two "Porsche tech" chargers, the one at Porsche Zentrum Berlin and the Innogy Duisburg station (beautiful place with solar panels) and these 350kWh chargers gave "ladefehler" errors when trying to start the charge. On the I-Pace screen you get "initializing" for a long time, "charging" for one second and then it fails. What made it more interesting is that the friendly Porsche people in Berlin told me that a German I-Pace did charge successfully there recently which could be because German I-Pace's run different software /BMS, at least this is what I'm guessing. Not done with this investigation yet!
