I left the car in -13°C to -17°C (7-1°F) overnight. And in the morning I tried to supercharge. It was super slow. It turns out that driving the car heated up the battery faster.
You can get free supercharging when buying a Tesla Model S or X by using my referral link:

A lot of people mention the max battery power option. Keep in mind that this setting will only allow higher max temperature (about 40°C vs 17°C on normal setting). It will still rely on the same 6 kW battery heater. Please read this before commenting.

Cool stuff Bjørn!! I was wondering though, is this procedure going to harm the battery and/or the motors? I suppose it's not a good idea to do it very often.. Still the car is under warranty, but you may want to keep it for many years.

Tesla programmed the car to be pretty foolproof. If the battery is too cold, there will be power output limits too. Look at this video: kzbin.info/www/bejne/pH_UhJuhn8xppLcm1s There, the car has been sitting still for a week in freezing temperatures. The power limit was at around 40 kW. I guess in my test with the Model X, the battery must have been around zero degrees celcius. That means it will take more than 8-9 hours to chill down 600 kg of batteries. Probably some 24 hours is needed.

Hi Bjorn, not sure if this is available for P90DL, but FYI, if you turn on Ludicrous+, you'll see the temperature of the battery pack which will help you gauge how much yoyo-ing you need to do while warming up the car.

Great Video.....I was just on a trip and saw my battery pack get down to 6 degrees. I went from a stay in a hotel directly to a supercharger. When I plugged in I got zeros all across the charging info, We sat there for 20 mins and still zeros all across. It took us 45 mins to get up to 30Kw. I didn’t even think about taking it out and driving it like you did to build up heat in the battery pack. This will be a big time saver this winter. Thanks.

KmanAuto made a video about battery heating. He showed, while monitoring the coolant-temprature, that the battery do not start charging before the battery temperature is above freezing. The target temperature battery heating is 8°C. BTW, it's not just the resistance from the battery that heats the battery while driving, if you look at the schematics in the "diagnostic mode", you can see that the heat from the inverter and motor can be dumped into the battery.

@ivaniclixx
@ivaniclixx 6 жыл бұрын
Not really true. Batteries will last longer if you keep them at low temp. What gets lower is the efficiency charging/discharging them. So, the best situation is keeping the car cold while parked, and around 25 deg. celsius while driving.
@MacGuyver85
@MacGuyver85 6 жыл бұрын
Yes and no. Yes, batteries last longer and degrade less when keeping them at optimal temp. But there is a threshold they shouldn't go below for charging. For example: if you charge a lithium battery when it's frozen it could easily be permanently damaged. That is what I'm talking about. Hence why I'm surprised Tesla lets their pack go below zero. Some more background info: the thing is, the lower the temp of the battery, the lower the operating voltage becomes, this is the same reason why a cold battery puts out less power/energy. So, if you freeze a cell the voltage drops accordingly. If you would charge a cell to its maximum capacity and then freeze it it will be dead since the energy stored will exceed the capacity of the cell. That also leads me to believe that this is handled at the pack level and thus the BMS. Freezing them and not charging them seems to be no problem though.
@ivaniclixx
@ivaniclixx 6 жыл бұрын
That's what i said and, you're not correct. In fact, that's what the video clearly shows. Hardly getting 1kw of charge after waiting minutes means the batteries are NOT allowed to charge when frozen. Once they start heating up, it slowly raises up. That's what the battery heater is meant of, and clearly it's not enough to heat up the whole battery pack quickly. solution: drive the car and heat the battery... Am i missing anything here?
@MacGuyver85
@MacGuyver85 6 жыл бұрын
Well, my initial comment was with the assumption the cells shouldn't be frozen at all. That was incorrect. Freezing them isn't a problem as I mentioned in my second comment. Charging them when frozen is (which I already knew). It's still surprising they don't maintain the battery close to zero degrees though, to facilitate charging at all times. Then again the 6 kW battery heater only needs 16 hours to drain the battery completely.

When I arrived at the charging station, it took 10 minutes before charging. Actually normal, if the vehicle switches off the recuperation then it cannot charge either. After 10 minutes he started to land slowly and became faster and faster ..

Like Bjorn said, this should be the last resort option. But do do it if you need to, charging lithium ion cells below freezing is a bad idea which is why the supercharging is so slow when the battery pack is cold. I would however be cautious if the temperature has been (and is) extremely low, well below -20C, as at that point aggressively discharging lithium ion's is a bit questionable from the endurance standpoint as well as the capacity. Obviously you'd want to have the battery heater keeping the pack warm.

When I switch to ludicrous mode, the battery temperature will raise up to 50 degree C. That means when you sleep in the car, set alarm one hour before you wanted to wake up and the another alarm for the actual wake you. Turn on ludicrous mode then the battery will heat up at much higher speed than regular mode. Note sure if this will work in Norway :-)

You could have just hit acelerator and brake pedal at the same time while standing still. Around 10-15 kW heat would be dissipated in the motor and heat the battery via shared coolant loop. And your wild guess of 10% heat loss gives 40Kw at 400kW output (at the gauge). But those 40kW happen only 1/3 of the trip time. So standing still with accelerator and brakes pressed at the same time should give you comparable results. And not stressing the drivetrain mechanically.

Tesla should implement this at the supercharger, so that you don’t have to drive. Just do the Jo-Joing with the grid or some powerpacks located at the SC or even another car charing there. The owner does not have to notice, just show an exponentially increasing charging speed, by gradually reducing the discharge time in favor of more changing time. However, I don’t know if this is good for the battery pack or if it doesn’t really matter.

Ha, the frozen SC cable that acts like a pine tree branch. Tesla has a patent for cable cooling system, should include heating too. The gas station pumps have the same problem though. I wonder how that charging cable acts in -30C. That's where the winter starts, warmer than that is still OK, not too difficult to manage, you can still work out side, but below -30C plastic parts will break, fluids turn to solid, rubber tires have parking dents, shock absorber fluids turn molasses and your car will stay tilted after a long curve. I cannot even imagine how bad it gets below -40, but I have experienced -37C and that cracked my shoe soles and I got flat tires just by moving a car a bit.

is there any reason why BEVs don't have what ICE have had for years in your colder climates which whilst an engine heater would be no use a battery heating element under the battery would be great?

Teslas do (the 6 kw heater he talks about), but Bjorn deliberately turned it off for this demonstration of what to do if circumstances are such that this situation is unavoidable.

Have you tried to switch to ludicrous/launch mode from a very cold battery? The car will tell you it will take 10 or 15 minutes or so to warm up. If it works cold, this is better as you don't have to drive it at all; you can stay parked.

Jim Whitehead he mentions in the video that the battery heater is 6kw The motor when push to its limit pushes at 400kw and if you account a loss of 10% that means the battery is heating at a rate of 40kw Therefore, heat loss from the the motor is much greater than heat from the battery heater.

That fosil is probabaly long gone.:D Man, you spend way too much time doing these experiments, but they sure are fun to watch. Btw, can you keep your car plugged in supercharger over night while you sleep in it, or you have to pay idle fees then? And if so, how much? Thanks.
@StevenPeeters
@StevenPeeters 6 жыл бұрын
Yes, you pay idle fees as soon as you're done charging. €0,40/minute. Also, it's not done to block a stall for that long. Camper mode works fine to keep the heat in the car and will not consume that much energy. Easily topped off again in the morning if you "camp" near a supercharger.
@bjornnyland
@bjornnyland 6 жыл бұрын
That's incorrect. In this case, I would not pay any idle fees. The idle fees start when the capacity of the supercharger has reached 50 %. That means that on a 8 stall supercharger, the idle fees occur when 4 or more cars are charging. During that night, almost no cars went there. But on the other hand, it's bad manner to park there after charging has completed. That's why I moved the car in the evening after charging.

I would probably only do this in tight situations. It's unnecessary wear on your batteries. Extreme cold can increase strain on the batteries which is the whole reason it warms up in order to charge. Discharging them under heavy load does the job of heating them up, but at the cost of creating strain the slow charge/warm up period is designed to avoid.

I just wonder if it might be another explanation about the heating effect. When using energy from the battery, the heating will be from inside the battery cells, instead of heating with the element, that will heat the cells from outside. The element will give a lag, and it means the battery heating need to be used for a while before the heat reaches the inside of the cells. Some math: Using 5,8kWh totally in 10 minutes, means 34,8kW of effect. To compete to the 6kW battery heater, in power, that means its necessary to have 1/(34,8/6)= 17.24% loss in battery.

Could warming up the battery this fast (by driving like a Norwegian) when it's so cold, potentially damage the it in any way? Feels a bit odd that SuC just gives 10 kw, but the limited regen around 08:10 seems to give more than that?

I don't think so. Tesla is very careful about programming the BMS. Their highest priority is to reduce degradation.
@b.g.i.6617
@b.g.i.6617 6 жыл бұрын
I thought that filling the battery the top 10% required a lot of time for the BMS to load balance the cells. When you quickly unload cells - cold ones - would you expect them to become UNbalanced? Would it be a good thing to fully charge and let the BMS fix any balance problems? Or do you just get it warm and head off into the sunrise?

If you have a P model, you can turn on "Max Battery Power" which works very nicely for me.I drove 80 mph for 20 minutes with only slight warming. So even the P model only has a 6Kw heater?
