I've searched here but not found this answer. I have just ordereda Y and am curious about its use for my wife's job. She drives about 80 miles/120km a day but works in her car for her job (lots of computer time between patient visits). Do you think she can make it through the 9-5 day, assuming she's running AC in summer, heat in winter?

All day idle--running AC/heat--possible?

In my experience with an LR Y, AC doesn't use much power at all. Less than 1% per hour. Heat, on the other hand, really depends on the temperature outside. Not sure you would get through a really cold day with the heat on all day and still drive that far.

This won't be a problem at all in my opinion, even in temps approaching freezing.

80 miles per day plus idling with climate control on will be fine. With climate control consuming about one to two kW on average, expect 35+ hours of run time on a full charge (70 kWh). Even with 80 miles of driving consuming 25 kWh (or less), you're still left with enough energy for nearly 24 hours of climate control.

Thanks all. This was my read but I wanted to confirm I wasn't missing something. It would seem you could run the climate control stationary for a very long time. The sales guy didn't have a clear answer and I figured some owners would. I will no doubt have more questions when I take delivery.
Irrelevant to this question but man do these boards do a lot to anti-sell the cars!

The nice thing about electric cars is how easy it is to do the math for these types of situations.
Looking at a worse case scenario, in the winter, the driving efficiency could be around 320 wh/mi, or 3.125 miles per kWh. For an 80 mile drive, that'll use about 25.6 kWh.
The AC and heat at lower fan speeds doesn't pull much energy, about 300-500 watts. At high fan speeds, it'll pull around 1.0 kWh. Let's say she sits in the car for 6 hours/day with the fan on HI (maybe she likes working in the middle of winter in a t-shirt, cabin set to 80F). This is 6.0 kWh to run the HVAC. 6.0 kWh plus 25.6 kWh, total energy spent 31.1 kWh.
For home charging, even if you use a NEMA 14-50 outlet and get 7.6 kWh, it'll take about 4-4.5 hours to charge. If you get the Tesla Gen3 HPWC and get 11.7 kWh, it'll be around 2.7 hours to charge back what was used during the day.
tldr battery pack is 75-78 kWh for the LR and P, worst case scenario daily consumption is about 31.1 kWh. No issues.
