yesterday’s vlog showed me that he’s doing troubleshooting of Tesla issues for free only with Scanmytesla app and his experience. Imagine if Tesla would give him some proper tools and money for additional car optimization testing etc. Keep it up man!
16:00 Heating is typically a static load, so the faster your speed, the smaller percentage of overall energy consumption that the heat energy represents.
@1:49 Bjorn, most people do not even have a Garage, they live in a city apartment, wake up an the car is waiting for them on the cold street, ice cold, not charged. It is different if you have optimal conditions owning such a car, like a garage, but most people don´t have one or can´t have one
Oh to live in such a developed country, lol! "You should have at least a 10% buffer to make it to the next SC". On Vancouver Island, which is about 1/10 the size of Norway, we have a total of 2 SC. With 10% you MIGHT be able to make it to another 50 kW charger, for which you would need to use your $600 Chademo adapter, and there may well be a line up, as there is only 1 or 2 chargers at that station. Love the video, as always. Thanks for showing us what the future might look like some day Bjorn.
Same here, I don't own a tesla, don't even really need a car, don't live in a very cold country (France), and yet, I still watch thoses video. Great content!
Thank you so much for all these tests for all teh nerdy out there, that is really appreciated. I have a 2018 LR AWD, so yes, the same test with MC Hammer or any no heat pump model 3 woud be great to see the advance in technology.
This is my favourite winter EV test! Would love entries for lots of cars in the Google sheet for these tests! Even if temps are a bit different it's really interesting! Important in the world of heat scavenging by some cars is to note starting conditions. Either battery temp or time pre-heating or fast-charging. Pretty please! 😊
Great video Bjørn! Specially the insights of using seat heating etc . Would be great to see the difference with MC Hammer as comparison to heatpump.....thx for 'suffering' the cold! Also looking forward to your ID3 adventures!
@@nakfan no, I mean the tests with ID.3 that he's mentioning right at the end of this video :-). I'm assuming he'll run the same type of tests in low temperatures to assess the cold weather behavior :-). Cheers!
I'm also interested in this test. According to a german test there is no difference between with or without heat pump in the ID3 (maybe a software problem?): th-cam.com/video/Zf-ikz0wrls/w-d-xo.html
Love these vids, but could you indicate somehow which number we're supposed to look at on the scan my Tesla app whenever you refer to it (e.g. left column second one down)? Thanks (by now I know, but for new viewers this is very confusing)
Driving the Ioniq 28kwh in - 26c is freaking insane, the consumption is going though the roof. But it charges like a boss, no slowdown of charging speed, at home on ac that is. That battery is buildt like a tank 😀 Now I wish I had a 100kwh battery 😂
Great test. A cold start video would be interesting - let the car stay outside for some days at less than -10 degrees. Since covid I think this is a quite realistic scenario
Amazing video, love to see the cold start vs warm! Next I'd like to see this test with similar temp and pre-heatpump M3 and maybe include this test for all cars you get during winter.
Wow, you are gaining 1k subscribers per day now? :) (okay, okay, I admit I have very few data points, but 1k more compared to yesterday, which was 1k more than the last time I checked)
also, could you do that exact same test (or as close as possible) with MC Hammer? Forget the aftermarket stuff, it would help a lot seeing the differences in the different scenarios regardless of comparing it with the 2021. of course, if you get an unmodified loaner from another follower, even better.
Norway is great. I walked there from sweden years ago in holidays. Great, how the electric car market is developing in Norway. I wish this for germany too. And its cool, exspecially in cold conditions like there, that you test the capabilities of the technology. Some people in germany still think that fossils are better in winter because of their inefficency (heat), but they are wrong, driving evs is more comfortable in cold because of the fast and quiet heating functionalities. But I am interested who the cars behave after years in the cold winters of norway, that is an open question, I guess, isnt it?
M3 LR AWD -21C cold weather 460 km test Saturday 9th of January 2021. I see in many comments on Bjørns M3 2021 testing in cold weather that you would like him to test MC Hammer the same way, but he said that it is a Performance with this and that, and he was not sure of the value of the test. Well, I have a 2019 M3 LR AWD and is driving approx 35-40k km a year. Frequently I have a trip between Jessheim (45km north of Oslo) and Trondheim through the well known Highway passing Nebbenes supercharger to Elverum and then Østerdalen to supercharger in Alvdal and then Trondheim. Many of you will not believe how terrible the conditions in winter have been in some of these trips and I have really got good experience with this car. Summarized it’s no problem at all. The trip is 460 km. I got my M3 in sept-2019 and ODO is now approx 37k km. It is with the 18 inch wheels and mud flaps in front is mounted. No insulation or other addons. I do not have any apps like Bjorn, so I am only reporting the figures from what you see on the screen in the car. Some settings used in the trip: Cabin temp 20C and gives comfort for me and does not feel cold. No jacket or gloves. Music always plays from Spotify iPhone BT connection. Autopilot speed settings used: 54 (50), 64 (60), 75 (70), 87 (80), 95 (90), 100 (110) Car was charged to 100% but was pre-heated before start so was 97% at startup. Temperature at Jessheim was -8 and quickly stabilized to -16. Passing Elverum it got colder and getting close to Rena (30km after Elverum) it got down to -21 and varied between -21 to -23. Several occasions Regen was set to low caused by ice and slippery roads. (Normal Regen is not good then, as the back can start sliding. Low is better. Should be able to turn off so the car worked as a petrol or diesel with automatic transmission.) 47 km before arriving Alvdal, the car started to pre-heat for supercharging. At this point approx 225 km driven. Consumption at this time was 194 whkm. Arriving Alvdal supercharge at 270 km with consumption 209 whkm. Supercharge gave 138 at start and went down to 75 when I stopped charging. Charging time 25 minutes. Gave +47kwh. Battery to 74%. After approx. 330 km (around Kvikne) the temperature started to raise and stabilized on -10 the next 100 km, then up to -5 and constant until arrival at destination. Consumption for the whole trip 191 whkm. Battery remaining 29% at final destination. I am using the car as any other car and is not in ‘saving mode’. Hope you found this interesting. Previous to my M3, I had Opel Ampera-E for a year and a half and drove 53k km with that. Was ok but supercharging was really not supercharging in cold weather. M3 is really in another league. I really love it.
Apparently 19ºC is supposed to be an optimal temperature for your home. The body stays warm and you're not using excessive heat to get your home up to 21 or in some case as high as 23º. I set my temp to 19ºC with heated seats on. I do feel as if this isn't using as much energy as just the heater at 21ºC. I don't have a heat pump and I can image that making a difference but probably not anything excessive. You're right 16ºC is just too much of a compromise especially when it makes just a difference of an extra minute of charging. :D
Haha shieeet Bjørn impressive he is testing the consumption without heat on. That is true commitment! but also very interesting to see how big the difference is in range without any cabin heat on in arctic temperatures :P
Thanks Bjorn for the really good test ! A winter performance comparison with ´M3 without heatpump´ could become an entry on longert-erm performance reference. To use it now in the context of purchasing ´Used cars 2020 models´ Then, a 2021 S/W update is round the corner A battery update may come as early as mid 2021
how we can calculate the overall efficiency in both conditions? a) battery is cold b) battery is preheated Keep in mind, the preheating is not a give away by the charger.
YES MC HAMMER TESTS, I have a 2020 M3 and am very salty about not having the heat pump (got my car in june). My driving pattern means its not a big deal really, but I love chasing efficiency.
Thanks for the info. Bjorn. As you have discovered that warming the battery uses more energy than heating the cabin, do you think it’s more efficient to use energy to warm the battery before a trip and then get a better wh/m or do you think it’s better overall to not pre heat the battery, save the energy but get a worse wh/m ? I guess it depends on the length of the trip but just wanted to hear your opinion ? P.S. I have the 2021 M3 AWD
I'm guessing for minimum kWh from the plug your better off not pre-heating too much. There will be significant losses between heating and reusing heat (which will start losing heat to surroundings). Better for range though obviously if you don't care abt kWh
@@krisany3670 That’s what I was thinking too Kris, the only thing is with a warm battery you also have more regen which helps the trip efficiency. It takes a long time for those dots to disappear and in that time I am using the brakes more than usual.
Love it! But would be so interresting to have such a Test without insolation... Because i think the most people would spontanously sleep in the car sometimes but wouldn't have isolation shields. I would be so curious.
16:03 maybe at 120 km/h the wind chill was stronger, so the heater ran at a higher level (which added to the consumption. And in general at higher speeds, there is, of course, higher consumption just by the higher drag at higher speeds)
Interesting test, makes perfect sense if heat pump can suck warm from battery/motor coolant! If there's no extra heat, meaby HVAC system have to use PTC electric heater.
Thank you for informative video and explaining that app for us! Good work! I'm concidering buying EV car, and it might be a Tesla. Is Tesla chargers cheaper than others?
Hi Bjørn, will it also benefitt to preheating the batteri befor leaving also when you are not conectet to charger, typical, home from work, or whil the extra you use to preheat be more than you save ?
On the high speed test you use less warming per km as you travel faster :) slow speed needs to heat the cabin for longer (and generate less battery heat loss).
@@bjornnyland Respectfully Bjorn, I think he did have it right. If it's using 1kW and you drive for an hour you've used 1kWh. If you drove 120 kms in that hour you used less energy per km than if you drove only 90 kms.
Hi Björn frohes Neues Jahr! Hast Du schon mal einen EV mit und ohne Wärmepumpe verglichen? Ich finde kaum Videos darüber ob der Aufpreis lohnt - Greez aus Hamburg!
Hi Sir I watched a lot of your videos. Currently, I am living in Canada so the weather in winter should be very similar as your place. Do you think if it's possible to drive model 3 SR+ without winter tires in winter?
Thanks for the solution to get fog out, next time my 2021 heater decides to not work. Cold is one thing, fog is the major danger. Especially if a scary tunnel comes up ( strømsås in drammen would be suicide without heater , worst fog tunnel i know of) Me and 2 of my friends now have iffy heatpumps, but they keep starting to work after you leave the car for 10-15 minutes , so we are still driving our own cars until our service appointments :-D Still thanks for the great videos
Physics is cool. Very cold air contains less water vapor then slightly cold air. So introducing colder air into a less cold cabin lowers the relative humidity 😉.
Hi Bjorn, please tell me what is more quiet inside the car on the motorway a Opel Ampera or the Model 3? I know that even the Model S is relatively loud while driving is it true? thx
Depends which Model 3. The facelift with the chrome delete and heat pump is even more quiet than the Model S 2019 version at times, whereas the Ampera can be compared to the 2019 Model 3 in terms of sound. I’ve owned MS 2019 and just ordered a M3 2023 after a test drive that lasted for several days, it’s superior with road noise up to 100 km, but rattles more over small potholes and bumps.
It will be interesting to see how the ID.3 will stack up. If you haven't done that test already, just a heads up: Nextmove already in-depth tested Heatpump vs No Heatpump with the ID.3 and found no difference between the two, probably due to the software not being ready
Bjorn I do a lot of traveling in America and I go into convenient stores and gas stations many times a week. Can you take ue into a circle k or one of your gas stations sometime?
Thanks for another great video keep up the great work. Your no heating run reminds me of our ioniq hybrid with its crap heating one morning it was -8 with no heating until done 10-12 miles only time in 20 years had to wear gloves and hat and big coat . Now got ev heating in on 22c auto all winter and love preheating and pre de-icing and lot cheaper to run and lot better to drive so evs for the win !
Bjørn how long would you preheat using the app (not plugged in to a charger) at -10 degrees to get that charge rate? I'm trying to preheat my car (model 3 standard plus late 2020) but I'm assuming not for long enough as it only gets around 20kw at most usually around 15kw this is off a 120kw supercharger. Thanks
@@bjornnyland Sorry, i meant that was why the difference in Wh/km was that huge : 21 to 13. For the kW difference itself, it's because as you drive faster, you pull energy faster from the battery, so it heats itself (Joule effect), it lessens the need of the heat pump.
@@bjornnyland I had some fun doing maths, it has been some time, so feel free to correct me if I'm wrong here. I wanted to try to approximate the internal resistance of the battery pack, assuming that the 400W difference of the heat pump was because of 400W of Joule effect heating inside of the battery pack due to increased intensity. 90km/h warm battery 175 Wh/km 175*90 = 15,75KW (power draw) 120km/h warm battery 228 Wh/km 228*120 = 27,36 KW I took the battery pack's voltage of 377V seen at 13:18 to find the intensity at 90km/h : 15,75 / 377 = 41,8 A (amps draw) at 120km/h : 27,36 / 377 = 72,6 A Joule effect : P = R*I² so delta(P) = R*delta(I)² 400W = R* (72,6²-41,8²) 400 = R* (5271-1747) 400/3524 = R R = 0,114 ohm !!!! sounds extremely plausible :) EDIT : I double checked and I think I did my end maths wrong, so I corrected
Bjørn, I think it would be interessting to do the same test procedure with an old (pre-2021) Long Range Modell 3 without heat-pump! Then your frosty M3-mission will be completed! 🥶 😉
I wonder. What is the best app for Norway to find all rapid charger/super charger, and how to pay for its use? It is close to a nightmare to find all the stations and how to get access to them.
My friend just bought a model 3 and he had 13% battery or 56 km and when he was driving to town about 20km from his house the charge went to 0% and the car went into limp mode. Now he has range anxiety. Outside temp was -8C.
Correction @19:41, Warm cabin, not battery (i.e. Confort). Since you didn't use the HVAC there, the battery temperature is not really relevant. Am I right? I think I saw the battery temp at about 15.5 °C during that cold run.
I almost got my self a Mg zs ev. For 361 euro a month private lease. We had a subsidie of 4000€ For 270 people this January on new cars in holland. But it’s already given away. Now the mg cost 100 euro a month more. So i’m disappointed. But the second hand ev subsidie is still there. But that is 2000 euro. I have my eyes on a nissan leaf private lease. For 345 euro a Month. Shall i do it? Or is it better to wait a year
I know it is nowhere near as cold in the UK but I always used to leave my climate control at 22 degrees in my Zoe ZE40 and the range never really dropped below 140 miles. The heat pump in the Tesla looks like it is really good - a pity it took them so long.
Bjørn‘s dedication is just legendary
To be the best you need to be
obsessed. There is no way around it.
He tested the shit out of this 3 LR model. He put more KM on it more than i do for 6 months 😂
yesterday’s vlog showed me that he’s doing troubleshooting of Tesla issues for free only with Scanmytesla app and his experience. Imagine if Tesla would give him some proper tools and money for additional car optimization testing etc. Keep it up man!

Bjørn is the EV ambassador of the world.
It would be interesting to see a pre-2021 model 3 performance do the same test.
Björn is the master of EVing
Yoda'ing it
He is the Lord Of the EVings!
EVil Björn 😂
Yep... An EWing was more like king of oil 😅
So much useful info for the complete winter driver, big thank you from Alex in Alvdal.
Hey Bjørn, you crazy ninja! Best regards from Darwin Australia, love your work!
Cold weather range test for Darwin is +16°C 😉 You need heavy rain range testing! Regards from -3°C low in Gisborne VIC (SR+ driver) 😉
I find these long range tests very informative, especially in cold weather.
16:00 Heating is typically a static load, so the faster your speed, the smaller percentage of overall energy consumption that the heat energy represents.
Hey Bjørn! Great video as always.
I would love to see a range test in winter with the SR+, preferably with the 2021 model :)
Your channel is always entertaining! Thank you!
This is just amazing. I keep learning more about my car because of Bjørn.

I do not have any apps like Bjorn, so I am only reporting the figures from what you see on the screen in the car.
Some settings used in the trip:
Cabin temp 20C and gives comfort for me and does not feel cold. No jacket or gloves.
Music always plays from Spotify iPhone BT connection.
Autopilot speed settings used: 54 (50), 64 (60), 75 (70), 87 (80), 95 (90), 100 (110)

Lots of interesting data. I have to watch this video more than twice to understand all variations of the "engineering pearl", octovalve is doing.
Great info about HVAC!! Thanks Bjorn!! ;)
We all appreciate your sacrifices... 😉
Yes please do it with MC Hammer when you have time. Would be interesting to see how it "behaves" without heat pump.
Nice video 👍🏻
an autonomy test with +30 ° (Italy summer condition) and air conditioner on would also be interesting

8:30 to 10:00. Tesla battery University course 101. Kudos+++
Loved the series! Would really love to see some tests with a non-heatpump model that has similar wheels etc!
Maybe MC Hammer then. But it might be too late because the extreme cold is going away soon.
Would be good comparison.
Loved your tests!!
You make the best movies, Thanks
I really wish we could see more information, like battery temp, in a menu on screen in our Teslas.
Yes! And something nice visualization of how much power goes to different systems!
Agreed, this would be an nice feature to have !
Especially if tesla can make a nice visualization for the information
Great review as always! Thank you for all you do!
The stuff I learn watching your channel, amazing. But I just set my HVAC and drive my Model Y as you suggest.
yes, please do the MC Hammer video!
great video as always
Also, the higher heater consumption for the 120 km/h test, is because the pach temperature was lower than with 90 test

Hi Bjørn, will it also benefitt to preheating the batteri befor leaving also when you are not conectet to charger, typical, home from work, or whil the extra you use to preheat be more than you save ?
Bjørn, what do you think of the beta scan my Tesla 2.0 UI? I don’t like it. I hope they add an option to use the classic UI.
On the high speed test you use less warming per km as you travel faster :) slow speed needs to heat the cabin for longer (and generate less battery heat loss).
No, you're mixing up kW (power) and kWh (energy). The slow speed should require less power (kW) to the heater regardless.
@@bjornnyland Respectfully Bjorn, I think he did have it right. If it's using 1kW and you drive for an hour you've used 1kWh. If you drove 120 kms in that hour you used less energy per km than if you drove only 90 kms.
definitely want to see what the data is like without the heat pump!
Hi Björn frohes Neues Jahr! Hast Du schon mal einen EV mit und ohne Wärmepumpe verglichen? Ich finde kaum Videos darüber ob der Aufpreis lohnt - Greez aus Hamburg!
Hæ?
Do the stopwatch on the v3 supercharger, it'll be a great ad for tesla!
Hi Sir
I watched a lot of your videos. Currently, I am living in Canada so the weather in winter should be very similar as your place. Do you think if it's possible to drive model 3 SR+ without winter tires in winter?
No
Same test with MC Hammer or if you could SR+ without heat pump would be amazing!
When will you test the new Fiat 500? 😊
So good. What a sacrifice for science ... driving in -16°C with the heating off and window open 🤗🤪😋
Thanks for the solution to get fog out, next time my 2021 heater decides to not work. Cold is one thing, fog is the major danger. Especially if a scary tunnel comes up ( strømsås in drammen would be suicide without heater , worst fog tunnel i know of) Me and 2 of my friends now have iffy heatpumps, but they keep starting to work after you leave the car for 10-15 minutes , so we are still driving our own cars until our service appointments :-D Still thanks for the great videos
Physics is cool. Very cold air contains less water vapor then slightly cold air. So introducing colder air into a less cold cabin lowers the relative humidity 😉.
It would be interesting if you could provide info about cost. Rates etc and deals of the different providers.
Professor Dr. EV Björn 👍
Hi Bjorn, please tell me what is more quiet inside the car on the motorway a Opel Ampera or the Model 3? I know that even the Model S is relatively loud while driving is it true? thx
Depends which Model 3. The facelift with the chrome delete and heat pump is even more quiet than the Model S 2019 version at times, whereas the Ampera can be compared to the 2019 Model 3 in terms of sound.
I’ve owned MS 2019 and just ordered a M3 2023 after a test drive that lasted for several days, it’s superior with road noise up to 100 km, but rattles more over small potholes and bumps.
I think the mc hammer is not an ideal car for the match, ask for another no heath pump model 3, could be perfect the comparison
I guess you maxed out the new tesla facelift :) every day a new adventure
Hi Bjorn, Have you uploaded the video for the eniro?
Tesla Model Fridge FTW!
It will be interesting to see how the ID.3 will stack up.
If you haven't done that test already, just a heads up: Nextmove already in-depth tested Heatpump vs No Heatpump with the ID.3 and found no difference between the two, probably due to the software not being ready
Also only heating battery from battery instead of from mains.
Yep I remember the temporary chargers at Gol!
Skal du prøvekjøre Mach-E snart? :D
Bjorn I do a lot of traveling in America and I go into convenient stores and gas stations many times a week. Can you take ue into a circle k or one of your gas stations sometime?
Thanks for another great video keep up the great work. Your no heating run reminds me of our ioniq hybrid with its crap heating one morning it was -8 with no heating until done 10-12 miles only time in 20 years had to wear gloves and hat and big coat . Now got ev heating in on 22c auto all winter and love preheating and pre de-icing and lot cheaper to run and lot better to drive so evs for the win !
Bjørn how long would you preheat using the app (not plugged in to a charger) at -10 degrees to get that charge rate? I'm trying to preheat my car (model 3 standard plus late 2020) but I'm assuming not for long enough as it only gets around 20kw at most usually around 15kw this is off a 120kw supercharger. Thanks
30 minutes
@@bjornnyland Great thanks for your reply.
16:00 It's because if you drive slower, you'll take more time, so the heat pump will work longer.
You did a classic mistake and mixed up kW and kWh like many other people here.
@@bjornnyland Sorry, i meant that was why the difference in Wh/km was that huge : 21 to 13.
For the kW difference itself, it's because as you drive faster, you pull energy faster from the battery, so it heats itself (Joule effect), it lessens the need of the heat pump.
@@bjornnyland I had some fun doing maths, it has been some time, so feel free to correct me if I'm wrong here. I wanted to try to approximate the internal resistance of the battery pack, assuming that the 400W difference of the heat pump was because of 400W of Joule effect heating inside of the battery pack due to increased intensity.
90km/h warm battery
175 Wh/km
175*90 = 15,75KW (power draw)
120km/h warm battery
228 Wh/km
228*120 = 27,36 KW
I took the battery pack's voltage of 377V seen at 13:18 to find the intensity
at 90km/h : 15,75 / 377 = 41,8 A (amps draw)
at 120km/h : 27,36 / 377 = 72,6 A
Joule effect : P = R*I²
so delta(P) = R*delta(I)²
400W = R* (72,6²-41,8²)
400 = R* (5271-1747)
400/3524 = R
R = 0,114 ohm !!!!
sounds extremely plausible
:)
EDIT : I double checked and I think I did my end maths wrong, so I corrected
When do you get kia e-niro to sleep in -26??
Bjørn, I think it would be interessting to do the same test procedure with an old (pre-2021) Long Range Modell 3 without heat-pump! Then your frosty M3-mission will be completed! 🥶 😉
I wonder. What is the best app for Norway to find all rapid charger/super charger, and how to pay for its use? It is close to a nightmare to find all the stations and how to get access to them.
My friend just bought a model 3 and he had 13% battery or 56 km and when he was driving to town about 20km from his house the charge went to 0% and the car went into limp mode. Now he has range anxiety. Outside temp was -8C.
Classic beginner mistake. Battery was cold.
Can you remove this tire monitoring system fault error? It is in every video you posted lately?
What tire pressures do you run? Is it consistent for all tests? Big change in pressure with temperature...
Of course.
Correction @19:41, Warm cabin, not battery (i.e. Confort). Since you didn't use the HVAC there, the battery temperature is not really relevant. Am I right? I think I saw the battery temp at about 15.5 °C during that cold run.
No, it was warm battery.
Good video!
@Bjorn Nyland It is Wxh per Km, not WxA
I almost got my self a Mg zs ev. For 361 euro a month private lease. We had a subsidie of 4000€ For 270 people this January on new cars in holland. But it’s already given away. Now the mg cost 100 euro a month more. So i’m disappointed. But the second hand ev subsidie is still there. But that is 2000 euro. I have my eyes on a nissan leaf private lease. For 345 euro a
Month. Shall i do it? Or is it better to wait a year
I know it is nowhere near as cold in the UK but I always used to leave my climate control at 22 degrees in my Zoe ZE40 and the range never really dropped below 140 miles. The heat pump in the Tesla looks like it is really good - a pity it took them so long.
