You have it. Just choose your nearest supercharger on your route and the car will automatically enable battery warming on your way to it.

@@roygardiner4002 That's bullshit, this is just a bad workaround. A Supercharger that I often visit is just 8km away from my home.

Great video. I have a M3 SR+ with a 55 kWh LFP in the US, and it's just starting to get that cold in my area. Limited sample size, but I haven't noticed any differences or a drop in performance yet either.

[@alexmat106]

Why isn't battery temperature indicated in all EV's? If there was a temp gauge in the instrument cluster, after the first few weeks of usage you could know what to expect from a charging session

[@GeraldMMonroe]

Or a metric called like "battery receptiveness" or something. It would indicate how much power, in kilowatts, the battery is able to take. This would factor in pack size, temperature, current state of charge, cell age, cell chemistry, and so on.

[@tomasj719]

Bjorn try to charge this car up to 100%. You will be surprised about charging speed :) On weekend after driving 150km I was getting 20kW at 98%. At Lier 250kW supercharger.

[@kruemelfelix]

Might be interesting, but on LFP batteries the amount of SoC which you arrive at chargers doesn't really matter anylonger. I hammered on the Autobahn some weeks ago and arrived with 70% at a supercharger and got 130kW peak still, around 70kW at 90%. The curve will just shift to the right. You can try it yourself :P And what is shown in this video is really a totally unreasonable scenario for most people I guess. If you charge with AC the car won't heat up the battery at all I think and if you start at let's say 80% the battery will be warm enough for 100kW+ at the next supercharger.

[@RandyTWester]

"There's always a Tesla Supercharger nearby". I'll remember that, if we ever get to Norway. The closest one to us in Canada is 99 km away. Unless our destination is the other way, then it's maybe across the Arctic ocean in Norway.

[@Isamu1013]

99km is close enough for the vehicle to start pre heating. Also I think they started to add other chargers to their navigation. And using scheduled departure you can pre heat the battery as well.

[@RandyTWester]

@@Isamu1013 But it's sometimes 99 km in the wrong direction. Usually in very cold weather the battery pre heater only comes on at about 70 km from the destination. It should be manually switchable. There aren't many other DCFCs either, Tesla's is the closest at 99 km. Going north or east there aren't any, anywhere.

[@sondac999]

For comparison LFP@25 degC: 90 kW. Ioniq5/EV 6(NCM with high nickel content)@25 degC = 220 kW (170 kW when adjusting for the smaller battery of SR+). Ioniq5 and EV6 lacks the preheating feature though. All cars should have a manual "preheat for fast charging" option :(

[@georgepelton5645]

Thanks for the interesting and informative video Bjørn. I do remember your video from a few years back when the Oslo underground park and charge facility was opened. Facilities like these make it a lot easier to ABC. 😀

[@davidsommen1324]

Bottom Line: don't leave your car at low SoC for the night and then expect to charge it fast the next morning. For most people not really a problem if they can charge overnight.

[@mattbrent8732]

Even if you can’t charge overnight you can manually pre-condition or schedule a departure time. Model 3 will try and pre-heat the battery and normally only takes 15-20mins to do this unless super cold. Max I’ve used is 2% soc to do this unplugged.

[@ungallegoenmunich]

Great tests. Love them. Note that Tesla added a bunch of new DC chargers (EnBw, Ionity, has to be, etc) that now also pre heat the battery. Also I believe the non-need of DC keeps the battery cold and does not affect the range too much. I think Tesla learned it through customers during last winter and now they are just better. The LFP with 60kwh is even in winter a 10/10 car. PS: one thing to 13:48. How do you define a little while? I tried myself, 30 minutes city+highway 120 and did not preheat the battery on purpose (limited to 32KW)

[@SHLDMusic]

It would be great if there was an indication of the battery temperature somewhere on the Tesla (I don't want to add an obd dongle). I know that with the "regen dot" on the dashboard that you can estimate the battery temperature, but that's not enough

[@ungallegoenmunich]

@@SHLDMusic yeah but we do not need to know the temperature actually. Only if you need DC you select the charger and it pre conditions itself. If you don't need DC, the car wont waste energy rising the battery temperature for no reason

[@capt4in1]

Were there a lot of dashes on the regen bar at the top of the screen? My SR+ LFP always has reduced regen in cold temps (I don't have the ability to precondition the battery before driving). It still regens, but it's not nearly as strong as in the summer.

[@dangr3957]

Charging in cold is it complicated question. I heard that it’s actually not good to for the battery and that’s why regen is not working when the temperature is below 14°. I always schedule the departure or manually turn on cabin heating and then I can see a tiny icon beside the battery and usually takes 10 to 30 minutes depends on the temperature. Overnight I keep the car on the driveway and put it on the slow charger. And keep it between 70-80%. Usually I calculate the overnight charging finishes in the morning. Even 1 or 2 kW slow charging is keeping the battery on the right temperature.

[@ipiiroin]

What are the differences between this LFP battery and USA made facelift model with heat pump in cold weather?

[@alanou]

I kind of feel this makes the previous range video incomplete. Maybe there's a need to make another range video... starting cold battery, then seeing range in the cold but battery preheated.

Hey Bjørn. I'm between Teslas right now. Waiting for a newer Y here in the US. But I heard a rumor that there was a software update that allowed you to navigate to a non-Tesla high speed charger and then if you go into settings for that destination you can tell it to pre-heat the battery. Is that true? The reason I ask is because we will be getting CCS adapters here in the states and so using more non-Tesla chargers.

Not cold enough! Please do a soak for several days at -15, then do a full charge cycle. This is the airport scenario, but actually some people who park on the street in cold climates may need to leave the car for several days too. To be clear, the scenario is you have to drive somewhere and don’t have enough range to get there, so not the same “just preheat the battery” advice.

That's my understanding of LiFePo4 as well. Charging at any rate below 0C cell temps will permanently damage the battery. It would have to heat up before any kind of charging/regen. LFP discharge rate is reduced as temperature drops, the de-rate curve is even more severe and linear than NCA, especially below 0C, as the Li ions are more "trapped" in the structure. At -20C, LFP output is extremely low and can also permanently damage the battery. NCA can withstand a little lower temps without permanent damage. I think around -25C?

Nothing can beat a Volvo with a diesel engine and engine and cabin warming system running on car's battery and burning half a liter per hour with timing function and app control from your phone...

bjorn is da man

[@zhgzhg1]

Is it RWD? Not AWD?

[@_TrueDesire_]

SR is RWD :)

[@SupremeRuleroftheWorld]

they should just make a button to manually preheat. get on it elon...

[@דניגדי-ג9ר]

what about model 3 ling range and model y lr range test in cold?

I thought Teslas charged fast, but the lfp M3 is not impressive.

[@SamuraiTacos1]

tesla is dope

[@Luis-xr9ye]

Kids do not try this at Home, this is for científic purpose only!

[@rolandrohde]

I wonder why it takes so long to heat up the battery. With so much Power going in and the heat pump adding to that...I feel like the pack should warm up quicker...but I guess heating a 500kg slab of metal takes time...🤷‍♂️

[@DG-uv3zw]

yes

[@onedankind]

Now try Canada cold weather -20 degrees. 0 degrees isn't that cold...

[@zodiacfml]

i thought the heat pump supposed to warm the battery?

[@bjornnyland]

Heat pump is also heating up the battery.

[@zodiacfml]

@@bjornnyland thanks! so heat pump cant keep up. but then, at a charger, using electric heater is not a bad design/engineering. weird it is not here.

[@ContraVsGigi]

So this is Tesla coldgating, as you always mention this term for other cars.

[@bjornnyland]

Nope. I clearly said this is a constructed case. Use the car correctly and it won't coldgate.

[@ContraVsGigi]

@@bjornnyland I don't get it, it is not "corectly" to go to change when you are having an "empty" battery? If you arrive home and need the car, but the battery is getting empty, you should not go to a charger?

[@Mekuso8]

It's not a constructed case, it's just the reality of people who live in apartments without a permanent charger.

[@bjornnyland]

Even if you don't have a charging option, you should still not end up with low SoC like this. If you're a clumsy owner on the other hand...

[@hikarisai7755]

I don't own an ev, it looks to me 20kwh is really slow? Looks like buying model 3 now with LFP battery will be very bad choice

[@bjornnyland]

It's 20 kW, not 20 kWh. And this was a constructed worst case. For normal case, you will get 100-140 kW.

[@Alekpowah]

LFP is not recommended for cold climates such as Norway then?

[@bjornnyland]

Not a problem. Remember that this was a *constructed* case. As long as you do things correctly, using LFP in Norway is not a problem at all.

[@Alekpowah]

But what if you had to choose, would you still pick LFP? I hear they can survive more cycles but it's still scary to choose LFP over lithium which is tried & tested.

[@monsieurb90]

@@Alekpowah LFP is also a Lithium-Ion-Battery. ;)

[@timr.6864]

Do it again for -10*C please

[@bjornnyland]

Not that cold yet. Wait until January.

[@reynoldichi1090]

Pro tips. Ev driver Please watch this video.

[@edc1569]

Try -20C!

[@bjornnyland]

Not that cold yet. Wait until January.

[@1983mack1983]

This doesn't qualify as a cold test at above zero. Leave it unplugged and sitting for a dozen hours over night at -20

[@bjornnyland]

It's not that cold yet. I could wait until January next year. But lots of people requested me to test this. So this test is still good and valid.
