You should expect at least 50% reduction in real-world range due to decreased battery efficiency, increased need for heating, increased vampire battery drain.
OPs dogmatic statement may be true for short trips and extravagant heating behaviors. I live in Colorado and see about a 15 - 20% hit in range on my 45 mile work commute. Longer drives would be less.
Is 50% real for the Model 3? In our S it's more like 30% at sub zero. The worst we've seen was a couple of times when we were driving against a heavy rain/sleet storm with high and pretty constant head winds. In that case our consumption went up by about 80%, so about a 45% reduction. We had to drive about 300 miles in that, so we wound up charging a couple of times. One thing about very cold (<10F) weather is that when you start out after the car has been cold soaked, the battery state looks terrifyingly low. However, it does recover quite a bit after it warms up. Another nasty effect is that the car won't accept much charge until the battery warms. We've found that it's better to drive around for 20 minutes to warm up the battery, then plug into a Supercharger, rather than plug in when the battery is still cold.
Even a number as extreme as 50%, which I think is highly unlikely, would still satisfy a lot of people’s daily needs with an SR or MR.
Agree with this. The rated range is drastically reduced in the winter. Honestly, the LR battery makes me a little nervous now that it's getting cold so I can't imagine having significantly less potential range.
1. Yes, you lose rated range in the cold. Welcome to owning an EV. 2. There's no way it's "at least 50%" unless you like the interior at 90 degrees and drive 90 mph.
This FUD gets posted every winter. Here is REAL WORLD data showing typical range loss of about: 40% below 0F (limited data, however) 30% 0-10F 20% 10-30F 10%-15% above 30F
I am able to avoid this by timing my charging to end proximate to the time I will use the car. My most recent long drive was this week: We left at 6:30 am and 17F, car range 303 miles. 250 miles later we had 13% remaining. In balmy weather we usually arrive with 22% SoC remaining.
This can’t be accurate. I will give you one example. Normally if I charge to 90% the previous day and drive to work for 25 miles I would have 80-81% left in summer. Now in 30-40F temperature, I will lose 3-4% battery overnight and will have 72-73% left after driving to work. I am only heating to 64F in my car.
"Can't be accurate?" So the data in front of you is wrong? (Or are you thinking I have somehow manipulated 30k miles of data)? Either way, LOL
I am seeing about 12-15% difference from the cold with minimal vampire drain. Average temps have been 10-35 degrees. I lose more from driving 70mph+ then from the cold.
Over the recent couple of cold spats in CO I've averaged about 280 wh/m when parking in the garage and about 300 wh/m on the one night I had to park outside (temp got down to ~20° F). Usage generally starts out high and then goes down as things warm up, so the longer I drive for the lower my average gets. My normal usage in warmer temps is about 260 wh/m, so no where near 50% losses (more like 8-13%). I do keep it plugged in at night so I don't have vampire drain to worry about, but I don't bother timing it to finish late so the battery is still pretty cold in the morning.
That may be correct, but based on the expected range on the battery indicator it's way higher. (battery indicator is not accurate I know) Last week on the highway using cruise control at around 70 I was seeing at least a 1.5 mile decrease in the battery indicator to each mile I traveled, maybe closer to 1.75. With 2 seats set to level 1 heating, and cabin set to 68. 15 degrees outside, all season 20"s.
I think it's important to distinguish between what range impact results from temperature alone vs. other things. If you aren't getting "rated range" in the real world at 70 degrees, it will look way worse in the cold. After 7 weeks and 5,000 miles of ownership my "lifetime" wh/mile is 289, and the real cold hasn't set in yet... Simple math says that at 289 wh/mile my total average range at 100% battery has been around 275 miles, not 310. I do a LOT of freeway driving for work and therefore speeds in excess or 70 MPH are very common for me. Cold temperatures make that worse. A cold-soaked battery and cold cabin at the start of a drive makes that even worse. Wet roads, wind, snow, elevation changes, and extra "cargo" can make it even worse. So it may not be technically accurate to say that cold ALONE could impact range by 50%, but I do think it's realistic to say that, in the worst case, your range could be impacted that much (or even more).
This is a funny thread. People comparing anecdotal evidence (this one time, in band camp...) to 30k miles of hard data to "prove" FUD. Yikes.
Hence why I can't buy a X75D. just check my signature for real world wH/Mile. that was over 15,000 mile average...
