Hi Bjørn. Thank you so much for your very thorough and wellcomposed films about the Tesla. All Tesla owners know their Bjørn. You've done a tremendous work, and you should know we appreciate it.
Hi Bjorn, after watching your videos over and over again, I have just taken the giant step and ordered my P85D, in Blue very excited , big thanks to your talent of video professionalism.
Bjørn Nyland A' propos "blue": yesterday, I was driving through a nice neighborhood here in Munich and thinking "hmm, this would be a nice suitable place to spot a Tesla". 100m later I came by a house, and guess what was parked in the driveway? OH YEAH, a blue Tesla Model S. Unfortunately, it already had gotten too dark to see which model (P85, P85S, S60, P85D) it was, and I was also going too fast to see. So, slwoly, they also spread here. :-)
I always pre-heat in winter. I agree its a great feature. I drive with range mode on and could see its' useful in situations where you are in the mountains X country skiing and need more range to get back home when no charging is available and after skiing body heat is so much only a little pre heat is needed so using the seat heater works fine. Pre heating the battery when charging requires the Range mode off then but going down a mountain of 1000 meters changes things and adds kWhs. Interesting stuff. Thanks.
Living in Utah, I've gotten to the habit of preheating on colder days, it's so nice. I have yet to try Range Mode to see if it really extends the range, I'll give it a try on my next road trip away from super chargers.
I am preheating sometimes my C4 GP but I stoped. Few weeks ago I have got information about stealing cars from diveway. Keys inside, engine is working. You are and Tesla owners lucky.
I live in a warmer place and the temperature in my garage stays over 55 degrees F in the winter, but when it turns cold I preheat to make the battery more efficient and extend range.
I watched this again because now I have my 70D, and winter is coming soon. But one thing I have noticed myself when using the preheating function -- It seems to me that the app can not change the settings for the climate control, except for the temperature. So for example, if you did not leave it in "auto" it will only work with whatever settings you left it in -- fan speed, recirc, etc. I usually do not leave it in Auto because I do not want the A/C compressor to run unnecessarily. This might be important in some conditions. E.g., if it is humid, you may want to the A/C to come on, but it will not unless it was left on or in Auto. By the same token, if you park the car outside and you expect snow or frost, it would be good to leave the car with the defroster set to on, right? That way the defroster comes on when you start the app. Do you agree? Also, you called this "preheating explained" but the same idea can be applied to "pre-cooling" in warm weather, so long as the A/C is on. One other point. If I leave a seat heater on when I leave the car, it is on when I return to the car. The setting does not change. So do you know if that means that the seat heater will also come on if you turn on climate control with the app? It is hard to tell, because the car turns on when you approach it, so that may be when the seat heater comes on.
+DAVID BRYANT Yes, the settings you left the car will be what turns on from the app. I try to leave it on auto most of the time. As for the defroster, it's good enough to leave it on auto. The car will defrost the windows. As for the seat heater, it doesn't turn on from the app. I tested it yesterday.
I do mostly one pedal driving in my ICE car. I learned to coast a lot. It's an automatic so I don't even have to put it in neutral. It just takes careful timing, different from an EV with regen.
Well, the Model S has a heat pump, since it has AC for cooling. I think it needs a 4 way electrically controlled valve (en.wikipedia.org/wiki/Reversing_valve) to be able to use that heat pump for warming. Home ACs have it so they could reverse the heat exchange ;). Resistive heating is considered inefficient and that's why it's better to have an AC in your home than a resistive heater. Another potential reason to leave the AC for cooling only is that it doesn't just cool the air that flows to the cabin, but it also dries it out by condensing the water vapour on the heat exchanger body before passing through the resistive heater to warm the air (ie you'd use both systems at the same time). This would not be possible if the heat exchanger is used to warm the air. Although below certain temperature (probably below 6C) the AC should be turned off, because it wouldn't be able to make the heat exchanger body cooler than the incoming air to cool it or dry it out. If you had this valve, then the AC would be wamring tha air and it wouldn't be able to dry it. But that's just a theory :). Ps, the Renault Zoe also uses AC for warming the cabin.
That's actually a very good feature. During winter, I constantly have wet floor because I pull in snow on my shoes. I always knock my feet together before entering the car to shake off some of the snow. But there will always be some snow getting in. All that water would cause the windows to fog and frost if it wasn't dried by the AC. I actually leave the HVAC on auto to let the car run the AC when needed.
If I was asked, I would make the heat pump like it is now, but put water heat-exchanger on either side. I would then have a series of valves, moving cold or hot water to the cabin-heater as needed, and the same towards battery, motor and a radiator in front. With a dynamic valve system, the heat pump could both cool the battery and heat the engine at the same time, or take heat from the engine and push that to the battery and internals. On a hot day, the radiator would be connected to the heat pumps hot side, and the cold side would cool battery, cabin and motor. That would work perfectly. If it got too hot, then motor could go directly to radiator too, and the heat pump could cool only the cabin and battery. Unlimited options, and how I am building my house heating system, with solar collectors, heat pump, external radiator, cooling and the works.
Dennis Mathias That seems obvious to me. It must be because it only gives you the heat that you put into it. An heat pump gives you more than you put into it. As you are reducing a high grade energy like electricity to a low grade energy like heat (heat being lower grade since you can convert electricity 1:1 to heat, but not the other way around), you should utilize the fact that you have a higher grade energy, and can get a lot more heat out of the same power, or use much less power. If you put 1kW electricity into a resistive heater, you get 1kW of heating. If you put 1kW of electricity into a good heat pump, you can, depending on temperature differences, get 2-10kW of heating, typically 2-4 at normal temperatures where you would use your heating. Not doing so, but rather use resistive heating, is sort of wasting energy.
Dennis Mathias I would but since you have failed to use any of the words "please" or "could you", go google it yourself: www.google.com/search?q=why+us+heat+pump+more+efficient+than+resistive+heating&ie=utf-8&oe=utf-8#safe=strict&q=why+is+heat+pump+more+efficient+than+resistive+heating
The Ford PHEV models have a weird reaction to a full battery and regen. They will spin the engine without any fuel or spark to generate engine braking. It's quite disconcerting when it first happens to you as it sounds like your nice quiet car is broken :)
Hi thx for the nice video you were talking about preheating the car while is plugged my question is can you preheat the car if not plugged for example you your out at mall and want go back to your car and it's cold and your car is not plugged can you heat the car using the battery ?
great video again bjorn, A while ago i sugested a topic, about how the acceleration and pedal position affects the range. I would be very intrested to know, what sportive driving does with the range. I testdrove the bmw i3 and the range drops about 40% when driving it sportive. Thanks cheers michel/belgium
Hi Bjorn! What about Range mode and Torque sleep? I mean in P85D, 85D and now 70D. I heard from various sources that in Software 6.2 you only can get the Torque sleep to work if you do use range mode.
I assume you can set the pre-heater to start at any given time? For example setting it to start each week day at 7 when you want to start to drive to work at 7:30, but not start automatic at Saturdays and Sundays?
With the latest software update 6.1 the car learns your commute behavior and will automatically start preheating 30min before you leave the house and work. I used to wake up and start the preheat process, I don't have to anymore. but if you are doing a trip out side your schedule you can still use the app
I am glad that someone is getting good use of the automatic preheating. With my widely flexible calendar, I will have no use for the feature unfortunately. I wish they rather added an alarm like fature where you could set preheating for the next day from the app. I do not like the visibletesla app. I am afraid of giving away my username and password to a third party, when it means that they might not just locate my car, but also unlock and start it.
Hi Bjorn, love your videos. I noticed in one of your videos you mentioned the fact that you could not get any sleep while you we charging because the heat would shut off every thirty minutes and you had to tap the screen or the brakes to get it to turn on again. Well the other day I was watching another tesla video of a person that successfully got a mouse to work with the tesla by hooking it up to the usb port, so I thought, could you get something like one of those "usb mouse jigglers" to keep your tesla "awake" and thus keep the heat from shutting off? That way you can camp in your car while charging and really get some sleep.
Hi, Bjørn, You said @10:28, that the car spends 6kW of energy for pre-heating. Isn't ist more likely 12, because of that the battery heater also needs 6kW more, and always runs if pre-heating is activated? Am I correct? Additionally, I noticed, that you're talking about kW in the whole video. Maybe you should mention, that this also means kW in an hour, so kW/h, right? So, one could also caltulate the range loss, he'll get through pre-heating. Actually, this would be also nice if the Tesla software would do this somewhere on the dashboard screens also. What do you think? By the way: again, it's a great video.
The heater will not go full blast if the temperature is set to 20°C. But if you set it to 32°C, it will draw close to 11 kW. The 'kW' means power. It doesn't make sense to say "kW/h". If you draw 6 kW for half an hour, you'll consume 3 kWh.
So the basic about the Range Mode is: If on, more power is delivered to the drive motor and less power delivered to other stuff like the heater. If off: More power is delivered to stuff like heater and a little less the the drive motor? Right?
Not quite. Range Mode will limit the amount of power going to the HVAC to 3 kW. Whereas Range Mode off will potentially let it use up to 12 kW. The driving performance is not affected at all.
I always preheat in wintertime. Love the preheat function in the app. Do any of you guys have some good advice to get rid of the regen braking blockage? I love the regen, and when I preheat the car the regen braking gets a little bit better but what to do to get full regen in the morning? Preheat with higer temp? Have the setting at hi? Great video btw:)
It would be nice if you had somewhere to monitor the power consumption rather than just the dial. Not just motor consumption. Maybe it does that but the resolution isn't that good. That way you could measure ac/heat, lights, fan, etc on an instantaneous case. It sounds like this is analog in that the heat isn't just on or off. It has in between settings.
Hallo Björn Nyland, When you preheating the car and the cabin starts heating upp. When will the batterys start to be preheated at a specific outside temperature instance. below -5 or what?
Hi Bjorn, Is there a big difference between the Model S & X when it comes to preheating and cooling etc.? I too enjoy your videos and one day I wish to maybe get a model X. When I am rich that is? Lovely cars sadly lovely huge price to own one. :)
Hey Bjorn Have you ever driven in like -35 degrees Celsius weather, the kind we get in Canada? Norway is generally a mild weather country but maybe some spots get cold. If you have driven in such temperatures, does the 6kW/6kW cabin/ battery heater keep up in such extreme temperature? What is the range in such weather?
Martin Pisz I have driven in -25°C once. The range didn't drop significantly. The heater could keep up just fine if it wanted to. I was probably just using about 2 kW of the cabin heater to maintain the temperature inside. th-cam.com/video/kRoV0pXJ6AI/w-d-xo.htmlm17s
I watched it months ago, today I've a bit more knowledge...I think. So if you really need range mode, it would be better to put it on once you are driving after pre-heating and put it off when you go charging. 😉
Yeah but it has nearly no effect if you turn it on when the car is preheated. So the actually usage is for people which do very often short trips. Like if you use the tesla as pizza taxi. Than rangemode would be a usecase. :D
Hi Bjorn, stupid but important question: in order to preheat the car you need a 3G connection in the car so if you park the car in a underground park you cannot connect to the car... I feel right? Is it possible to switch on the preheat of the car with the clock of the car?
Yes, that's correct. The car must have 3G connection. There's heated timer yet. Maybe Tesla will implement it later. After all, they have implemented timer for charging.
Bjorn, thanks for the video. A suggestion though.... If you make some notes before you start there'll be less jumping backwards and forwards and fewer.."errr, yes....,and another thing" moments... Keep up the good work though.
I've found a very helpful documentation on insideevs.com/tesla-patent-outlines-sensible-approach-cabin-heating about a patent of Teslamotors about the heating and cooling systems of battery and cabin. This is much more sophisticated than you explained here and I wonder if this scheme is realized in the actually produced Model S and X.
What happens when your battery is fully charged from regen and you are still going downhill? Do you have to rely only on brakes or the electric motor is still able to generate drag despite being at full charge?
Due to the information that Range mode prevents battery heating while preheating the car (I've found this information in a Tesla forum earlier last week) I've switched Range Mode off and discovered that the battery was not preheated at all. So did this behaviour change with firmware 7.0 or is it a fault in my car?
+Bjørn Nyland I always preheat at least 20-30 minutes. Outside temperatur was between -0.6 to +6.0 degrees Celsius last week when I recognised this issue the first time.
Bjørn Nyland I did this already 2 days ago, to my SeC Düsseldorf. Haven't got an answer yet. :-( Will send it to ServiceHelpEU@teslamotors.com also now.

Zoli1972s That's awesome :) Btw, it's called 85D or P85D. Media and others tend to call it "Model D". There's no such Model D.
Bjørn, this was a typo of course. I'm aware of the existing models as a Tesla fan :-) However, I've corrected it.
Very, very late reply but... how are you liking the car?

That's possible with VisibleTesla, yes. The mobile app can only switch on the heater on demand (manually), with no schedules.
You can set up the schedule from the car, right? I seem to remember a calendar button somewhere.
Morgan Tørvolt Yes, you can schedule charging from the car. But it's not as flexible as VisibleTesla.
With the latest software update 6.1 the car learns your commute behavior and will automatically start preheating 30min before you leave the house and work.

Good idea :) I thnink an easier and more elegant implementation would be to make a dedicated Camper Mode app.
Bjørn Nyland
This sounds like you're planning to make one. If yes, I'm sure you'll bring up a video of it.
Hi, Bjørn,

@@bjornnyland you will consume twice for an hour. 6kw (30min) 12kwh
So the basic about the Range Mode is: If on, more power is delivered to the drive motor and less power delivered to other stuff like the heater.

Not quite. Range Mode will limit the amount of power going to the HVAC to 3 kW. Whereas Range Mode off will potentially let it use up to 12 kW. The driving performance is not affected at all.
Bjørn Nyland Okay. Now I got it. Thanks :)
So no battery pre-heating unless also cabin pre-heating, is that correctly understood?
Yes, that's correct. Advanced users should be able to only activate the battery heater.
I always preheat in wintertime. Love the preheat function in the app. Do any of you guys have some good advice to get rid of the regen braking blockage? I love the regen, and when I preheat the car the regen braking gets a little bit better but what to do to get full regen in the morning? Preheat with higer temp? Have the setting at hi?
Great video btw:)
Set it to insane/ludicrous. [In the wintertime] These modes heat the batteryback much more, so the battery can accept more Amps :)
It would be nice if you had somewhere to monitor the power consumption rather than just the dial. Not just motor consumption. Maybe it does that but the resolution isn't that good. That way you could measure ac/heat, lights, fan, etc on an instantaneous case. It sounds like this is analog in that the heat isn't just on or off. It has in between settings.
Hallo Björn Nyland, When you preheating the car and the cabin starts heating upp. When will the batterys start to be preheated at a specific outside temperature instance. below -5 or what?
GEEEEKYYYyyy!! I LOVE it!!!
Hi Bjorn, Is there a big difference between the Model S & X when it comes to preheating and cooling etc.? I too enjoy your videos and one day I wish to maybe get a model X. When I am rich that is? Lovely cars sadly lovely huge price to own one. :)

plz explain about ac. how much power it use and how much it drow when u keep it on for 1hr
Watch the whole video.
Bjørn Nyland you mean for even cooling it use same power
hemant giri Cooling consumes less power. About 1-2 kW.
Bjørn Nyland thx for explaning

What if the car is in Africa, in the garage, can it be cooled down? 15-16-17 degrees C?
I've found a very helpful documentation on insideevs.com/tesla-patent-outlines-sensible-approach-cabin-heating about a patent of Teslamotors about the heating and cooling systems of battery and cabin. This is much more sophisticated than you explained here and I wonder if this scheme is realized in the actually produced Model S and X.
What happens when your battery is fully charged from regen and you are still going downhill? Do you have to rely only on brakes or the electric motor is still able to generate drag despite being at full charge?
Then there will be no regen until some of the energy on the battery have been spent.
Meaning you can *only* rely on brakes to slow the car down during the descent?
Cω Tham Yes.
Thanks for the info, Bjørn Nyland.
In hong kong, the temp is around 12 to 18 degree in winter, should i off the range mode ?
C or F?
Bjørn Nyland It is C.
steve au It depends on your driving habits. Try with and without and see the difference.
Due to the information that Range mode prevents battery heating while preheating the car (I've found this information in a Tesla forum earlier last week) I've switched Range Mode off and discovered that the battery was not preheated at all. So did this behaviour change with firmware 7.0 or is it a fault in my car?
+Jürgen Lennefer How long did you preheat and what was the outside temperature?
+Bjørn Nyland I always preheat at least 20-30 minutes. Outside temperatur was between -0.6 to +6.0 degrees Celsius last week when I recognised this issue the first time.
Jürgen Lennefer You should ask Tesla if there's an issue with your car then. I have no problems with heater in similar conditions.
Bjørn Nyland I did this already 2 days ago, to my SeC Düsseldorf. Haven't got an answer yet. :-(
Will send it to ServiceHelpEU@teslamotors.com also now.
1:26 did anyone else see that going down his hair? i wonder what it was.
What going down?
+Bjørn Nyland that ball of light it started at like the top right and went to the bottom left (of your hair)
PiggyHD Maybe it was light flare.
Bjørn Nyland k nice video though
