E-tron GT does not like Alpitronic-Charger (300kW)

Hello, I’ve been working on this topic since the beginning (09/2023) and I’ve played down 8000km and now I’ve come to the conclusion that my GT doesn’t work well with the Alpitronic chargers. In other threads I’ve already mentioned that I rarely get the full charging power until never, and if, then only for a short time (max. 2 minutes, then the car throttles down in 50kW steps (so 250kW to 200, then 150, then 100, to the natural charging curve). I was already there, nothing was found. I will soon get a data logger installed in order to get real readings so that Audi can play with them. On the topic Alpitronic: This manufacturer is now dominant in the market and on every corner to find, for me this was mainly EnBW, now Aral Pulse, and in between times by suppliers like Clever and E.ON in Denmark. At none of the 300kW-Alpitronics (i.e. the older ones with 4x75kW modules) I got a clever charging process n, despite low SoC (below 15%) and long pre-conditioned battery (about 30 minutes. Pre-conditioning at approx. 16°C outside temperature. Partly also over an hour on the highway conditioned). Ionity goes perfectly as it should be. Tested with the tritium and ABB chargers. I’m slow with my Latin at the end. Can it be that the GT and Alpitronic don’t get it in line?
