It's more than that. EA can't seem to manage power delivery properly. When I had the Audi it was 150Kw consistent from 0 to 80% and multiple times I had to play musical chargers because I was only getting 15Kw or 30Kw etc. You'd call EA and they'd just blame the car but yet you move it to the next charger and surprise, surprise you get 150Kw or you get 150Kw and within minutes it drops down. The experience is just unreliable, It wasn't a case of the battery not being pre-conditioned either because Audi keeps them at the optimal temperature all the time for fast charging (similar to ID4 etc.)
There is a particular location on the I5 in CA that has 6 to 8 EA chargers and it's so hit and miss whether they're working or not. When they are the same thing happens, you play musical chargers to get the speed you're supposed to get. A Taycan owner pulled in recently and connected to the 350Kw charger and couldn't get any more than 45Kw so he was waiting for me to leave to connect to the 150Kw as I was getting 150Kw. EA claims they struggle with power delivery in remote locations and that's an acceptable excuse yet at this particular location you look over the road and there's 50 V2 Tesla Superchargers delivering consistent speeds. So, how can Tesla do it, yet EA can't? It's not like Tesla is using a different power company in that location.
