What Would You Do If Stuck?

[jhalkias]

I don’t have personal experience at this. I also have a standard range battery so it wouldn’t last as long as the extended range. All I do know is that the range has decreased from 210 miles (I have AWD std range) to around 170 miles at 100% so I figure the battery wouldn’t last that long sitting in the cold.

Part of the decrease in range calculation is due to the fact of using E Heat or other heating for climate control. So it is not just because of the cold effect on the battery that the range decreases.

Yes, I am aware of that and furn off e-heat in cabin and use seat heaters when battery usage is an issue. But cold weather decreases battery efficiency due to its effect on chemical reaction in battery. In honesty, since my car is our daily drive I run the heat all the time because range is not an issue locally and I keep the car at 90% SOC.

There's this thing called weather.com and you know when a storm is on it's way. You know 4-8 inches of snow is tough in any vehicle when people are on the road.

I usually look at the weather when traveling and have simply spent the night somewhere to avoid being stuck on the road. I have done this twice. It's not wise to try and beat a storm....

Having just sat in a line for about 3 hours idling with the heater on....

3 hours with heater set to auto low, temp set to 72F (it was 25F outside) consumed about 6% of my battery. That would translate to about 50 hours if I started at 100%...

There you go again. You're killing a perfectly good thread full of wild guesses by giving us facts. Sheesh! ?

I thought I read it drew 7Kw. Either way, the math is easy.

Very doubtful the Mach E heater is anywhere near 7kW. Here's what a 7500W stand-alone heater looks like:

The rule of thumb is a single candle can keep a car space well above freezing. And it’s easier to stay warm in still air as opposed to breezy. That candle produces about 100 watts, about the same as a human. When I drove my ‘62 bug to school n winter I’d pick up 3 friends just to warm up the car.

but a down sleeping bag, thick wool blanket, warm cap, gloves, etc… can make a huge difference.

Which also means the seat heaters alone would keep the car above freezing.

The vast majority of drivers don't plan for "what ifs" on a trip. They leave the house in 20 degree temps with no blankets, water, bucket to pee or poop in, etc. No flashlight, no idea where their car jack is, don't keep the gas tank at least 1/4 full, ....

I95 is a nightmare to drive. In a major snowstorm, you should expect the worst. I assume that anyone with 4x4 simply drove down the shoulders if they could. Why the police didn't back people up the ramps and off I can't imagine.

I keep a 12v electric blanket under the cargo floor with jumper cables and a tow strap... between seat heater, at about 100watts, and an electric blanket at about 100watts, I'm guessing I would not need the cabin e-heater at all and the HV battery would outlast any ICE vehicle gastank even if I had a partial charge.

What sorcery is this? Predicting the future? Burn the witch! ?

I would get soooo good at tic-tac-toe.

Same as an ICE car except for one big difference.

In an ICE car I wouldn't get any sleep from worrying about a snow drift forming around my exhaust pipes and dying from carbon monoxide poisoning.

This...During the Texas freeze people died running their ice vehicles in closed garages to try to stay warm. Judgements aside (people get desperate and don't think things through), if they had an ev to warm up in/charge their devices in their garage it would have been a better outcome.

Knowing I have an EV that I could idle with no worries about CO for however long I have battery power to warm up/cool down and charge things if the power goes out gives me an extra level of comfort.

TRUTH. On my recent trip just with traffic because of time of day, I95 added 2 hours to my trip in stop and go traffic in GOOD weather.

I just keep looking back at @Mopey 's survival kit. -35F\-37C Real World Mach-E Range Test. What could go wrong?

Yeah, that’s 7kw at 240VAC not 400VDC.
Also that’s a coil in air; not a coil in coolant. Very different designs.

At 400VDC 7kw is 17.5 amps; basically a 22 ohm resistor equivalent.
