If the battery is cold enough it's not capable of discharging any current. Once you're below zero F battery cell temp you get to where that happens.
That's roughly half of the year in Chicagoland.
I guess I'll have to wait

Doesn't really work that way.That's roughly half of the year in Chicagoland.

Does it need to be plugged in the whole time?Some screen shots that may be beneficial
Car sitting in the garage. Car is plugged in and sitting at 79%. Every few days it will drop a percent or two if you don't drive it but it will kick in and get you back up to 80%.

Turn on the heat or you can schedule it to turn on before you leave for work and it will set it to whatever temp you last used.

Around 5 minutes later, heating has been completed.

The percentages you see at the top are my phones battery![]()
No, not at all. If you do it at Hy-Vee, it will just be using the battery instead. I'm not sure how much battery it would use but I would guess less than a couple of percent. Really it's a lot like remote start on a normal vehicle. The garage scenario above would be like if you had remote started but filling your tank up at the same time. Kind ofDoes it need to be plugged in the whole time?
This stuff has been my day job for the past 6ish months or so. Part of it is the battery management and part of it is the cell temp. The battery C rates (how fast they can charge/discharge) are dependent on temperature and state of charge. Air temp doesn't mean much but battery cell temp does and what it can to at different temps changes if you're in charge mode or discharge mode. The battery packs I'm working on will take 3-4 days in -20C air temps to get the point where discharge is a problem because they're so big. If you're plugged in then the thermal management on the vehicle should take care of that all in the background and you'll never know it's an issue. Again this will vary between the cells (Panasonic vs LG or whatever) and the battery management will make some decisions in the background but -20C cell temp (not air temp) is where you're going to lose the ability to discharge the battery in most cases.That doesn't sound right at all. The biggest issue with Lion batteries is charging when they're super cold. They can safely discharge current (assuming they have charge) at temperatures well below 0° F. I have a DIY temperature sensor on my back fence that has been happily operating in < -10° without any issues. I can post the data sheet if you want.
Note: I'm not up to date on Tesla's latest cell chemistry, just 18650's that you can buy off the shelf (nothing special). So while my info is possibly wrong, I doubt it.

It would be interesting to take an EV total cost and an ICE total cost and break down what the cost per mile was on each over the life of a vehicle. Although in the end it would still be a little guessing since things like knowing electric cost/gas costs will be; things like that.Costs me about 3 cents a mile to drive an EV.
A lot of those studies have been done already.

They do.Those studies would have to include the maintenance costs since EVs are much cheaper to maintain.
I've been using software to do just that. It really depends a lot on how much you charge at home and what your energy costs are. 95% of the time I'm charging at home and it costs me 11 cents per KwH. This equates to $3.56 per 100 miles. So 12k miles per year would cost me $427.20. If I drive my SUV, which gets around 21 miles per gallon, I would use 571 gallons of fuel, which at $3 gallon would be $1,700. But then I have to pay extra taxes because I drive an EV, so take off $130. So roughly $1,000 year.It would be interesting to take an EV total cost and an ICE total cost and break down what the cost per mile was on each over the life of a vehicle.

I think this is going to depend on your manufacturer, warranty, where you live, rebates, gas prices and how you use it.A lot of those studies have been done already. Over the lifespan of a vehicle, an EV is cheaper is most circumstances.
So the break even is like 20 years?I stated it before, but from 12-6am when I have my charger set up to charge my Rivian, I'm at $.028 kWh. Other times of the day its around $.09 kWh on average.
That really depends on your local electrical rates and how much you drive.So the break even is like 20 years?
wut?So the break even is like 20 years?
Trust me, it's not worth itwut?
It costs me $3.20 or so, to go from 0 to 100%.
