Does you HPWC start even when it is not the set time?

[jboy210]

Hi,

My car is set to start charging at 1 AM. However, I noticed ever once in awhile, when I plug in my HPWC in the middle of the day my HPWC will start charging immediately. It does not run for long, because if I check 10 minutes later the car is NOT charging. It is just strange.

Anyone else see this behavior?

If you are in the car and the HVAC is running then it will draw power from the HPWC. It will also draw power if you are standing there with the door open watching to see if it will draw power.

I am always out of the car, doors closed, and just plugged the connector (i.e. I am standing at the connector) when this happens.

My model 3 charged at 8pm 2 nights ago despite my 2am start time

First time I have seen this, I figured it was a glitch with the latest software version

Yes, it has happened to me every so often over the 6 years I owned my Model S. It runs for a couple of minutes immediately after plugging it in. Since I had just finished driving I figure it was some kind of brief conditioning. Never worried about it and never caused any issues.

Thanks. That describes the behavior. I guess I will just watch it and see what happens. It is more of an oddity than an issue.

This is normal behaviour. The car checks if the charging station is communicating OK and closes the relay to check what kind of voltage is available and IF there is any voltage available.
And if your car is "on" (any doors open or MCU is active), the car will use shore power from the charging station if available.

Another thing that will kick it off is turning on the climate control remotely (i.e. from the app). It takes power for heating or cooling from shore power rather than the battery which is certainly what I want it to do.
