EQS consumption in winter

My EQS 450+ was in a well ventilated public garage in Hamburg for 2 days. So the battery was well cooled and thus at about 1 degrees Celsius. With a battery level of 52% it went back to Berlin and it was planned to charge at IONITY in Heiligengrabe (branch A24/A19). On the way out at slightly higher temperatures and warm battery the distance with 40% charge (always around 130 km/h) was to be achieved. This time the consumption went down very slowly – I guess the battery heating was running at full speed. The display remained high for a long time and the battery level sank accordingly. I would probably have made it with one-digit battery level up to Heiligengrabe. But then I decided to go to the fast charger in Ludwigslust to have some buffer and through the fast charging e I have recalculated: On the above described route HH-Heiligengrabe the EQS has pulled in the average 30 kWh / 100 km. That is a considerable difference to summer time. That would be possible instead of the quite manageable 550 – 600 km range only about 350 km. I am curious what happens with real winter with -10 or -20 degrees…
