The trick is to put the car in mode 2, where the green light on start button glows but car is not in ready mode.

Found a neat trick in the car to run air conditioning during DC fast charging.
While we know that turning on the car while the car is charging is not recommended, I wanted to figure out a solution to avoid sitting in a sweltering car while it is charging.
After scouring the UK forums for an answer, it looks like there are three modes for the car’s power on state.
- Press the start button without brakes applied. You will see an orange light come up. This enables basic usage of the car like power windows etc.
- Press the start button again without brakes applied. You will see an green light come up. This turns on the air conditioning but without turning on the motor. At this point, the entire vehicles is powered by the 12V battery. So running for extended periods on this mode will drain your 12V battery.
- Press the start button with brakes applied. Car goes into ready state with motor turned on. This is the mode that is not recommended during DC fast charging.
The trick is to put the car in mode 2, where the green light on start button glows but car is not in ready mode. During DC charging, the 12V battery is charged as well which I was able to monitor through the driver’s screen. The air conditioning works as usual.
I don’t know if this works while the car is AC charging though. Also, I felt that the air conditioning doesn’t work when the car is put in the same mode while it is not charging. I believe it runs only the blower to prevent exhausting the 12V battery.
Would love to hear if others use this as well.
