Sweet. Thanks man. May I suggest doing a truncated 2-3 minute version? The generation of instant gratification media consumption may be scared off by the 8min time stamp. I found it very helpful and think others will too. 👍
Love it - thanks for doing this video. I love how your brain works - setting up the other camera on the tripod to catch the sounds - well executed! One tip (nothing to do with the Tesla) - I noticed that when you closed your garage door, you entered the code on the garage keypad. It looks like you have the same kind of keypad that I do ... and I recently discovered that to CLOSE the garage door, I only need to hit enter - no code required. Try it and see. It blew my mind, I've been entering the code for nothing for years!
Thanks for that, Ed! As for the garage door opener, you are absolutely right. It's something I knew even when I was shooting this video, but sometimes muscle memory kicks in.
Thanks for the info. I wish the app had a way to ONLY heat the battery or ONLY heat the cabin. It seems inefficient to run the cabin heat for 30 mins to improve my regen dots (i.e., lower the number of regen dots).
I'm not positive because I've never used the scheduled departure setting. (I don't leave the house at regularly scheduled times.) However, as I understand it, if the battery is cold enough, then the per-conditioning will turn on the battery warming process.
It depends on how cold the battery is. If you see the snowflake icon on the car display or the app, it will take longer to precondition the battery; perhaps as long as 30 minutes or more. Without the snowflake, the battery isn’t as cold, therefore the preconditioning will take less time.
So essentially, if the car is plugged in (not charging) and you turn on the hvac, it automatically uses power from the grid to precondition the car rather than using power from the battery?
If you live in a warm climate, you'll likely never need to warm up your battery. Depending on how warm it is outside, if you turn on the HVAC from the app, the battery warming process will be bypassed because it will already be at a nominal operating temperature.
Were you plugged in via a 120v outlet or 240v? Do you have to be plugged in, or will the Model 3 use power from the battery to heat itself when not plugged in?
Good questions, Tom. For the video, I was plugged into a Level 2 charger (48 amps), but the battery warming will also work when connected to Level 1 chargers (12 amps) and when not connected to a charger. However, your range will decrease when warming on battery only, and your charging speed on Level 1 will be extremely slow because most of the charger energy will be used by the warming process. Also, if you have a Level 2 charger, it's a good idea to schedule your departures (if you're on a regular schedule) because charging the battery also warms it.
My question is can you warm the battery and leave it plugged in and warm the battery by engaging the car heater prior to driving? Why do you have to unplug?
musinclind37: As I state at 00:46, the only reason I unplug the car is to display the battery temperature on the screen. In other words, I had to do that for demonstration purposes only. It is NOT a step required to warm the battery. You can leave it plugged in (or not) and all you have to do is turn on the HVAC to start the battery warming process.
Yes, because you still need to warm the battery in cold climates. Neither the heat pump nor reactive heater (in the earlier Teslas) does anything to warm the battery. It's only the turning on of the HVAC that runs the battery fluid through the drive motors, and that's what actually warms the battery.
@@nujxad The heat pump is an HVAC device and maintains the cabin temperature only. Heat pumps are extremely efficient and can either heat or cool the cabin air temperature.
Fresnel, the HVAC, seat heaters, and battery warmers aren’t interconnected. In other words, they’re all separate systems that shouldn’t directly affect one another. However, there may be an indirect effect when the car isn’t connected to external power and you turn on the HVAC. In that situation, all of those systems are drawing current from the battery, which results in an increase in battery temperature. Also, if you’re preheating the cabin & battery while the car is charging, the battery will get warmer as the battery charges. The effect would be more pronounced when connected to a supercharger where the high current makes the battery warmer. But when you’re connected at home on a 48 amp circuit, the HVAC, seat heaters, and battery warmers take so much of that current that there’s very little left with which to charge the battery. At that point, the battery charging process would not warm the battery very much.
@@ssoulssurfer Turning on the HVAC will prompt the car to measure battery temperature. If that temperature is low enough (I don’t know what the cutoff is), then the battery warming process (running the battery coolant through the motors) will begin. It will stay on until the batteries reach a nominal operation temperature, meaning you brake regeneration will be almost 100%.
@@mattlth Interesting thanks. In some video, somebody mentioned that if only using a 120V charger, and model 3's plugged in but not driven for a week or 2 and it's sitting in colder weather, that you can actually get a net negative charge because the system is trying to keep the batteries warm... is that possible/realistic? Any method to hep prevent that? I'm getting a model 3 soon but live in Alaska, the car will be in a garage but temps inside the garage can get down to 45-50F in the winter.
@@ssoulssurfer Because the battery warming process requires a lot of current, on 110-volts it would likely start to draw from the battery, thereby reducing your range. To prevent that from happening, I’d recommend not running the warm-up process for very long. That means you won’t have a lot of regenerative braking when you first start driving, but that’s likely preferable to losing range. As for losing range when the car isn’t driven, I don’t think that’s possible unless you’re warming up the car by remote throughout the time it’s parked. In other words, I don’t think the car will warm itself up. My garage isn’t heated, so it can get to the same temperatures you’ve described. But I do have a Tesla connector that supplies 48-amps of current. I’d recommend something faster than 110-volt charging. It works, but only charges at between 3-5 miles per hour, and probably even slower at really cold temperatures.
I just want to know how to pre heat the battery prior to getting off of work when it’s zero degrees F. Using my phone app. Either with the car plugged into a charger or not plugged in
As shown in the video, turn on your HVAC to preheat the cabin, which also turns on the battery heating process. Be careful to monitor how much energy your battery has because the process will deplete the battery, thereby reducing range. I'd recommend starting the HVAC 20-minutes before you need to leave, but make sure to leave yourself enough range to get where you're going, or to get to the nearest charging station.
Interesting thanks. But is there a material difference in turning the Hvac on by pressing the fan icon and manually adjusting the interior temperature of the car before leaving? In other words, if I set the interior heat to 75 for 20 minutes before leaving will that be a bigger drain on the battery than your method?
If the HVAC is on, it will drain the battery, regardless of whether you're in the car or not. The only way to prevent that is by plugging the car in. The battery heating process will also drain the battery. But as far as I can tell, battery warming only works when you're not in the car. Also, if you turn the HVAC on from inside the car, it will turn off if you get out and walk away. That's why you have to use the app when you're not in the car for both the HVAC and battery heating process to stay on.
@@mattlth To warm the battery in cold climates, instead of turning the HVAC on, use the rear defrost button in the Temperature section. You will see the app will display MAX instead of the temperature, and that will accelerate the process. Been there, tried that.
If I follow you correctly, I'd have to do that from inside the cabin because there currently (March, 2021) isn't a way to turn on the rear defrost from the app, right? If so, then if/when I leave the car, the rear defroster will turn off. What am I missing?
Why shouldn’t you leave your charging cable on the ground?? Is that just because it opens the possibility of running it over or it is something more technical? Thanks
Nothing really technical about it other than a shock hazard if got wet from the snow melting off the top of the car in wintery regions, or some other unforeseeable situation. It's always best to store things where they're designed to be stored. Also, I'm not proud enough to say I'd never run over the charging cable. I have my rare days of boneheadedness.
Is the scheduled charge the only way to have your Tesla connected without charging? And to confirm, the HVAC uses connected power and not the battery when the wall connector is connected?
It would be good to have the option to not heat the battery if you don't want to, in other words it would be good if there was a separate heat battery option. Tesla use a very clever way to heat the battery by running the electric motors inefficiently even when the car is stopped they can send current through the motor which heats it up and the coolant transfers this heat to the battery, all without using a separate battery heater.
I'd say you're letting your battery get too depleted for the climate in which you live. I'd recommend you search for resources regarding driving and charging a Tesla in very cold climates.
You don't need to be charging the battery in order to start the warming process. However, charging the battery during the warming process will heat the battery faster.
It depends upon how you turn on the climate. If you turn it on from the car's onboard display, it may start the battery heating process, but I haven't tried. However, if you turn it on from the app AND the battery temperature is cold enough to limit the regenerative braking, then the battery heating process will engage.
Diesel trucks u hook up block heater. For this if I have garage I'd close door of garage and put on propane heater. If no garage I'd get a huge heating pad and put under car
There are strange people out there who do strange things when they know where you live. I'm sorry you hate the tape. Other options included using a ruler, which I would have had to affix with...tape. If you have other options, please share your ideas.
Yes, it will. However, it will be very, very slow compared to using the heating process shown in this video. Also, the amount of heat from the charging process will vary by charging current, and supercharging will be very slow on a cold battery.
If you’re talking about the Scheduled Departure setting, you are correct. But as far as I know, the Charge Start/Stop settings never engage the battery heating process, although charging the battery does get it warmer.

TLDR: turn on the AC from your app to warm your car.
Saved you 9 mins, you’re welcome.
Thank you for this demonstration and explanation. This is the best video I’ve seen on this subject so far!
Thanks for sharing your experience. I do warm up battery before start driving to prevent range loss.

I preheat the cabin for about 15-30 min. and then the dots are only a few, and they disappear after a few km. I have the car plugged in
Thank you sir, you are a gentleman and a scholar.
