Can the Tesla S Handle this?

I drive 80 miles each way to work. I live in the Mid Atlantic in the US. I commute on a highway where traffic averages 75-80. The calculaters on the Tesla website do not allow you to put the vehicle speed past 65. Would a a Tesla S with the big battery be able to handle this commute in hot weather with AC running, and cold weather with heat traveling at 80mph? I drive a diesel now, which helps on gas.

Would you be able to charge at a 220V outlet at work?

We have made several 160 mile trips traveling on freeways with speeds tipping 80 MPH for portions of the trip. We get home with +/- 60 mile range left after starting on max range charge. ( This with a few low hills along the way plus a 1,700 foot climb to our home on the final 15 mile stretch)

I don't have a place to charge at work.

You should have not problem with the standard charge, but if you could also do a max charge for the first couple of times and see

Depending on the temperature you would not need to range charge above 50 driving 80 MPH. Below 50 degrees you may need to range charge for a little extra insurance.

I wouldn't do it. there would be a real risk of not making it in the cold, and you can't range charge it if you are using it every day. Add to that the fact that the battery will slowly degrade over time and it doesn't look like a good situation.

Now if you could get a plug installed at work you could do it with no problem.

I don't think you'd have a problem. Extreme cold might present an issue, but I doubt it, just use your seat heaters and cut back on the cabin heat. Even a 110V outlet at work (use extension cord!) could get you some cushion miles.

Hmmm, I'm surprised by the cautious responses. I wouldn't be worried at all. Assuming 85kWh, my experience with a few 40 mi commutes (avg speed about 70mpg with some segments faster and slower) during the colder part of the winter with 21 inch tires suggests that you would be using a maximum of 30kWh each way. Even filled to standard charge, you should have lots of buffer. 19 inch tires should improve things even more. Maybe others have had a significantly different experience, though.

At 110v over 9 hours should give another 13kW+/-. That should be good for at least another 30 miles.

Use EVTripper's planner and compute with actual and hypothetical locations and conditions:

After 4,500 miles in mild California weather driving in the 75 mph range on Highway 5, I have experienced getting about 80% of rated range.
Standard Charge 85Kw = 240 miles of Rated Range

If 240 miles x 80% = 192 miles @ 75 mph (constant on cruse control)

Given that 192 / 160 = 120% or 32 miles to spare, your AC and/or heat should not consume more than 5% of range.

You should be fine.

I've driven around trip of 220 miles in 14 degree F weather with a 4 hour stay half way with no problem. Still had 30 miles remaining when I arrived home. Much of the trip was at speeds around 75 mph.

The issue would be if you are leaving the car unplugged in very cold weather for extended periods it will drain the battery. (the Model S heats the battery to prevent freezing)

I agree with others, having a 110v plugin at work would definitely alleviate any concerns. This should be easily achievable as there is likely incentives for your employer to install plugs for EV's.

When it is really cold, you just drive slower and you will make it with no problem on a standard charge. In my out-of-town trips, I keep a watch on the energy usage. A bit of headwind - drop the cruise 1-2mph. Not as much HVAC needed as planned for, bump it up a couple of mph.

There are a lot of Californians on this board. What you need to understand is that snow and other winter conditions greatly reduce range. Add to that the vampire drain during the day and I would not want to be in the position in which I would have to range charge 20-40 times a year depending on weather to be comfortable.

As lph said, even a 110v plug would make a big difference.

Try entering your route at http://evtripper.com/planner/ which is said to be a pretty accurate planning tool.

I also live in the mid-Atlantic region and drive 80 mi each way to work. Generally takes 100 mi of rated range to go 80 actual mi. You should have no problem. I plug into a 110 at work just to have a little breathing room and pass slower cars with abandon.

I agree that in real cold < 30 degrees, I would range charge otherwise standard charge would be fine. I live in Chicagoland area, had my car since Dec 11 of 2012 and have over 5000 miles on it already. I have been thru the cold and feel comfortable with this. In the winter if you would be able to charge on even a 110 outlet, you probably would not need range charge at all.

The best options are (1) tell your spousal unit we need to move closer to my job, or (2) tell the boss you're starting your own business close to home. Either way buy a Model S for the thrill of it.

80 mile commute would be a piece of cake...
Not even an issue with the 85 battery
Enjoy

Thanks for all the replies. I think to be feasible, I need to be able to charge at work. I worry about the days its near freezing, and having it sit 10 hours in the cold all day at the office after driving 80 miles, and then completing the last 80 of the 160 daily commute.

It will be less of an issue once the vampire drain issues are gone, but still a bit uncomfortable for my tastes!

I live on East Coast as well. My P85 with 21" wheels was getting about 80% of stated range when it was colder, but now with spring temperatures I am getting generally 100% of stated range, with a drop to about 90-95% when I have AC running. Today in mixed city and highway driving with AC on, I averaged 310 kwh/mile. I am not driving conservatively, either, although I accelerate at a moderate level despite the frequeny temptation to gun it.

@Pbfoot - just an FYI. If your electricity cost is near $0.10/kWh, and you drive 1000 miles per month, then the cost difference between 300 Whr/mile and 360 is about $7, even considering the Vampire load.

You have a Performance 85? It's begging you to gun it!

@CarstenM
THX for the EV Trip Planner, looks really great. Pitty it doesn't include other EVs like LEAF though.

For other EVs, try this:

I live in the northeast too (CT). We were also getting about 80% of range in very cold weather (20 degrees F) and are close to target now (probably more like 95% of range, unless I'm racing some hapless BMW or something. I think you wouldn't have any problem - although I agree that being able to charge it, even a little, during the day would really make it a no brainer. I do worry about vampire losses until they fix the current problems in the software.

I've made a few 160 mile round trips with my 60kWh battery at max charge in 30 degree weather and arrived home with 8-12 miles to spare. The 85kWh battery should have no issues on a standard charge.

One thing I do in cold weather in the morning is turn the alarm clock off and turn the Tesla app on to heat the car and warm the battery. Also switch the app to max charge which starts the charge then switch it right back to standard charge. That way the battery gets topped off the full standard charge and there are no losses from heating the car.

I have driven LA - Santa Barbara (180 actual miles) several times on a single charge. P85 model, but the weather in SoCal is mild. When I do the drive I charge the night before to MAX range. Have never tried it on a standard charge.
