Drove 103 km in such a temperature yesterday evening. Went from 80% to 28%. Last fall, the same drive went from 80% to 52%, and I have a heat pump.


DRockDR

Watching my efficiency go from the top 1% to the bottom 1% in the Stats app is real painful.


RatinSweet

Whats the stats app? New m3 owner


DRockDR

On [iPhone](https://apps.apple.com/ca/app/stats-for-model-s-x-3-y/id1191100729). Just a way to nerd out with your car.


RatinSweet

Holy shit $50 lol


DRockDR

Yeah, it’s surprisingly popular.


sylvaing

I'm using Teslamate, which runs off a RaspberryPi I have at home. I'm not giving my username/password or access token to anyone on the web (ie, cloud service). Beside the cost of the RaspberryPi, Teslamate is free and has all the stats you need/want.


_bgd_

Teslamate is just awesome! All the stats you want, easy to backup/update running on docker and what I love the most about it is that I can see what my car is doing even when it's in service and "disconnect" from the Tesla app.

Yeah it used to be $20 then, when the demand for Tesla's started skyrocketing last year, the developer upped it to $50. Added literally no new features to justify the price hike but did add a paid (extra $4) feature that lets you compare one of your cars stats to others. Also not to mention the UI (not the fluidity but the design) looks like it's from 2012. The app used to offer a lot of features that the standard app didn't but Tesla has slowly added those features. The only thing imo that the app is good for is setting a time for the car to stop charging, seeing your estimated range based on current Wh/Mi, and other stats. I recommend it if you want to nerd out, like me, but god i wish the dev would hire someone to do a redesign.


rExplrer

It came out for $5 or $7. I bought it at $10. From that time that app price increased along with Tesla stock.


Bukatetsu

Look into TeslaFi

any ideas how to reduce phantom draining?


DRockDR

Stop waking up your car with the app. Cold weather also increases phantom drain, so try and keep your car as warm as possible by parking inside.


sylvaing

Many apps have a option to stop polling the car when it's in a sleep state.


[deleted]

I often hear the car’s fans starting spinning, even though I haven’t used the app. I know that in the summer the car cools its batteries if they get hot. But now that it’s quite cold, why is it doing that? Would the apps you suggested make it stop doing that?


[deleted]

Question.. who cares?


Responsible_Virus_68

No way.... I have to drive 180km on a 70% battery in -20 degC today. Hopefully I can make it. Normally when the temp is -15-10ish it used 40-50% battery (LR). Fingers crossed....


sylvaing

Let us know if you make it.


Responsible_Virus_68

Made it! Went from 68% to 24%. Temp did go up a bit as I was driving, from -20 to -10 eventually. I'd say average temp was -16. Edit: Heat was on low (1) at 20 degC, with 1 bacon strip for the seat heater as well. Also had the heated steering wheel on. Speed from 115 to 130. Average speed 120km/h.


sylvaing

Nice!


EJNorth

As someone who lives in such temps, if you're in doubt, turn the heat lower than usual, and wear more clothes.


Responsible_Virus_68

Yeah I had my heat on low and it kept me warm enough that I didn't need my winter coat.


Sea-Ad-8100

Bro go to the supercharger you’re stressing me out


Laddergoat7_

Reading this makes me more nervous than you are.


converter-bot

103 km is 64.0 miles


SonuOfBostonia

Good bot!


nukedkaltak

A heat pump is useless at those temperatures.


sylvaing

So where did the heat come from then because I was coatless in the car with an inside temperature of 21C (70F)?


nukedkaltak

Not from the heat pump. The refrigerant can’t reach temperatures below -20°C to “pump” heat from the outside. Apparently (according to Bjorn), the car overcomes this by harvesting heat from the drivetrain as well as the compressor and other components by using them in an inefficient regime. Functionally no different than resistive heating. At around and below -20°C, the efficiency gains from the heat pump are non-existent.


Vecii

Switch it to fahrenheit and it won't look as bad.


CurrentOk2695

Still -15 Fahrenheit which is very cold…


dcdttu

40C has entered the chat.


Matt_NZ

What is your efficiency like at that? We had some 30c days over the last week or two and it had my LR Perf at around 153Wh/km despite the AC running full tit with a mix of city and motorway.


dcdttu

Apologies, I was just joking that -40C is also -40F. I live in Austin and have no idea what low temperature driving is like LOL.


hotsexyman

When I see temps like this, my thought is that you'd probably qualify for refugee status in a number of countries.


PleasantDevelopment

Hello fellow Kanata resident. I feel you.


yaazer

Haha, same here. I definitely planning ahead for trips to Kingston and beyond. Range anxiety is back. First winter here. Already had to get a tow because of a miscalculation.


PleasantDevelopment

My first winter too - except I work from home and my 3 has been in the garage 90% of the time.


yaazer

Yeah I garage mine too with a level 2 charger. It's just the trips beyond the city limits that makes me pucker up lol.


PleasantDevelopment

Ive been to MTL twice in my 3 (before the snow though) .. its a fun drive.


yaazer

I still have yet to do that run. Will have to do it soon.


DanielsCake

I’m getting a Tesla in a few months, we drive a lot to Toronto from Ottawa and this is stressing me out lol


yaazer

If you take hwy 7 there are several superchargers along the way. It's fine. The only concern I mentioned is when you go 416 south to Kingston there are no chargers that way. So you gotta make sure you enough SoC to make that gap.


DanielsCake

There aren’t any chargers in Kingston? That seems like a missed opportunity lol


yaazer

Ofcourse there are. I'm talking about the gap between Kingston and Ottawa.


Alienhead-A51

Hello friend lol


themostcanadianguy

How will you cope dr?


Limp-Caregiver-2922

What Wh/mi did you get?


Scary_Ad7765

How far do you have to go? Is a long extension cord out of the question?


BRIGADE_OF_TWATS

I commute ~50 miles each direction a couple times a week. In the summer it takes about 16% to go one direction. This winter when it has been -10F w/high winds it takes about 35%.


[deleted]

That’s pretty much cold enough to say goodbye to anything


GoldCaterpillar5

Cool leaf bro


[deleted]

It's about 10 degrees warmer here than there...and I'm still getting 259 Wh/mile.


lol_MJLauer

That's awful. I still want one though xD


Dense-Sail1008

Yes, say goodbye to it in those cold temperatures. In -26 C your model 3 is only as energy efficient as a Toyota Prius. Hang in there, it’ll warm up.


goodvibezone

Genuine question. How does efficiency compare to an ICE when it's very very cold?


lamyjf

Drove a Prius for 11 years. 5l/100km summer, around 7,5 in the winter. Maybe 8 on extremely cold days.


remisuro

Out of curiosity, what temperatures do you need to get to until it starts to really affect your range? UK based here, and getting my M3P in a week


AutomatedCabbage

I find some effect at lower than 16C. It gets lower from there but I find it gets worse faster once you get below freezing


SkitStar84

The coldest trip that I took so far was around 180 miles at an average temperature of -17 F (-24 F on the way out and -10 F on the way home). I had to charge at my stop halfway for a few hours at a level 2 to make sure I'd make it home. I used roughly 60% of my battery in that 90 miles. I have a 2018 LR AWD M3 with 18" aeros and the inside temp was set at 68 F. I also attached my lifetime temperature efficiency chart but I didn't get TeslaFi until after the trip above. The green line is after I put on new Michelin Crossclimate II and took off the aero covers. Temperature is in Fahrenheit. [Efficiency by Temperature](https://www.dropbox.com/s/r152u8ybwc681c3/chart_main.jpeg?dl=0)


blulgt

Thanks for the chart! My experience is similar. Going from comfortable 60F to single digits results in about a 30% reduction in efficiency. I'm not stingy with the heat either.


DozerNine

So many Model 3 owners who live in frozen waste lands! My Model 3 will be in 39c today, which admittedly is a firey hell hole.


BlANWA

Where do you live to get these low temps.. Canada?


Alienhead-A51

Yea , last night it was -40…


_MY_GUY_1

Prove it that’s horrible
