Like many, I have my car set up to start charging overnight. My car is usually fully charged by 6am or 7am and I typically leave the house at 8am. I have been cooling the car via the phone app for about 10-15 minutes before I leave. So, I start cooling at about 7:50am. Does the car automatically draw energy from the HPWC just by virtue of being connected or do you have to actually be actively charging while cooling the car?
