Power Consumption during Camping Mode

[boykin]

Long time lurker but I don't post a lot. But I have a question.

The other day I used my Gen 2 R1S to stay somewhere overnight. Luna mattress and "Heat Shields" on the windows make this super comfortable, private, and lots cheaper than getting a hotel on Cape Cod.

There was a Level 2 Charging Station there so this was quite handy. I parked, put the truck into camping mode, set "Manage energy" to on, and turned off the displays. I wanted the A/C on as it was high-70's and humid. I set the temp to 70F.

I am very aware that the truck does not turn off in this mode but I value my comfort. . I also did not need very much additional charge for the return trip. Indeed, I was worried that, while sleeping, I would be fully charged and that would be a problem.

What I did not expect was that 3 hours later, with a solid 7.7kW being fed from the charger, my charge level had dropped by 2%. I turned off Manage Power and, as expected, was charging at the expected rate.

The next day for the 1 1/2 hour return trip, temp high-80's, the energy monitor reported my using roughly 4kWh for non-propulsion during the drive. But the overnight experience implies the truck was using ~8kWh in camping mode!

I have done car camping in the past and, while charging was certainly slower, did give me additional power.

Anyone have any idea what I (or the truck) did wrong?

Were your outlets on? The inverter is an energy hog...

Camping mode even with outlets and AC should not use anywhere near 7.7kW. What was your charge limit set at? Did you have a charging schedule set? Why were you worried about being “fully charged” - wouldn’t you just set your limit wherever you wanted it to stop charging? Did you ever confirm that charging started when you plugged it in?

Outlets were not turned on (good question to ask though). I just went out and put the truck into camping mode to see if it would have been easy to fumble-finger it. Answer no: I would have had to tap on Outlets and then set a timer/schedule. So no.

I do not have a charge schedule set.

Why was I worried: A) I do not like to hog a station when fully charged, B) I did not want to be charged an "idle fee" after the car hit the limit.

Yes, I am positive it was charging. When I noticed I was not adding to my charge I turned off manage energy and I was then gaining power.

No, I did not screenshot the energy screen (hey, it was the middle of the night, I wasn't thinking about debugging it!)

I started the charge session with 62%. Limit was set to 90%. Three hours later (I, ahem, needed to pee) I was at 60%.

No, I did not capture I a diagnostic log. And No, this does not make any sense to me either; which is why I asked the question.

When I get a chance I will repeat the experiment.
