Cabin warming

[XLTTOM]

I should know this but how much of the battery is used when you are plugged in while warming up the cabin ?

Depending on what your EVSE is providing to your truck, none of the battery could be used.

It’s a level 2

You should be fine. I think the heater for the cabin is max 6kw might be wrong so someone can correct me. So on a level 2 I would think your battery would be untouched.

Thanks for the info

Initially the cabin heater can draw 8 or 9 kW, but that only lasts a few minutes. Once the cabin heat gets close to the set point it backs off and the steady state draw is more like 1-2 kW. I was watching the numbers just the other day as I was plugged into a level 2 waiting for the highway to open after a closure. Outside temp was just a couple of degrees below freezing so not super cold, but a good data point I think.

Speak for yourself!
The cold is good to visit, but not to live in IMHO!
You probably feel the same about the heat!

As other say, if you're plugged into level 2, all energy for heating will be replaced with the charging energy, the AC is converted to DC and most of it is consumed by the PTC and related systems while the truck is in climate / remote start mode.

If my battery has already reached its SOC goal, then I will see a brief spike to 17 KW [FCSP @ 80 amp setting], which is the OBCC testing the battery briefly to confirm no additional charge is needed, then the OBCC tappers back to around 9 KW about enough to feed the heating or cooling operations. About 5 minutes or so and the energy flow continues to tapper down the remainder of the time cycle if you have set a routine of 10 or 15 remote start duration in the truck settings.

Depending on outside temperatures and how high you set the requested warm value, you'll use 2 to 5 kWh of shore power energy.
