Implausible Range Estimates after power cycle?

[kubel]

Does the truck normally recalculate incredibly pessimistic range estimates after power cycling (5 minutes off) at a lower state of charge?

I was getting 1.4 mi/kWh (carrying a big load, I'm ok with that efficiency), was around 46% SoC, guess-o-meter was saying somewhere around 70 miles and it was about 44 miles to the next charging station, so I was confident I could get to the charger. I stopped at a rest area for 5 minutes, and came back to a range estimate of 41 miles, not enough to get to my next charger. Nothing changed, just 5 minutes powered off.

I had to double back and charge at a closer slower station, and I that's when I took this picture of the dash. 34%, 31 miles estimated, 1.4 mi/kWh. It doesn't come close to adding up.

Could you update your vehicle data, year trim battery?

It's calculating as if an SR battery but worse.

Does the ATV ramp have lighting that's plugged into the 4 pin trailer hitch?
Does the truck think your pulling a trailer, I'd switch that off.

Updated profile, this is a Flash (LR battery). Mad Ramps do plug into 4-pin, but trailer is not enabled and I got correct range estimates with it plugged in earlier and later in the trip. It was only after the 5 minute power down. Could it have defaulted to a trailer enabled on power up and I didn't notice? Is there normally an indicator on the dash (other than cross traffic disabled) that indicates a trailer is enabled?

One thing I thought of after the trip is I should have enabled a trailer on this trip so it remembers my efficiency in the future with this setup.

It's like the onboard bed scales are calculating a high weight in the bed. Oh wait, most of us never did get bed scales, so we have no idea how they work.

You can't trust the range estimate. Stick with math, it won't lie to you.
131kWh * .46 * 1.4mpk = roughly 84 miles.

I think you would have been fine to continue, assuming you are able to maintain that efficiency. Around 25% is what would have been required to go the 44 miles. You can always slow down even more if your efficiency drops.

I can't remember if there's something to let you know about reduced range, but I would not be surprised if the truck powered on and "saw" something connected to the trailer port and reduced range. That's a bummer you ended up doubling back. I think setting up a "trailer" profile for that setup is a good idea. Keep in mind when you are in tow/hual drive mode, it will turn on battery conditioning which will use up a little extra power and might impact efficiency. If you don't need the battery conditioning it should be more efficient to use normal mode.
