What % of Battery Will AC Use?
Down here in Texas where the temperatures get to be over 100° most summers cars sitting outside can get up to 130° inside. Under extreme heavy use does anyone know what percentage of a battery charge air conditioning will use in this situation?

Tesla Model S
I've been driving EVs (Nissan, Mercedes B250e and Tesla Model S) for 10 yrs in California and Indiana. My experience of the impact of temperature on range is as follows ...
Heavy AC usage (100F+) will reduce range by ~ 5-15% (Nissan 15%, Mercedes B250 10%, Tesla 5-10%)
Heavy Heating usage (Sub 32F) will reduce range by 35-50% (Nissan 50%, Mercedes B250 40%, Tesla 30%)
I expect the EQS to be comparable if not better than the Tesla Model S

I was a little disappointed to learn that the heating is not done via a heat pump.
AC COP (coefficient of production) is much higher than heating due to the Carnot cycle. typical range will be 8-9.
This means 1 watt of battery = 8-9 watts of cooling.
Electrical Heating COP is 1 plain and simple. 1 watt of battery power = 1 watt of heat.
