I Deep Froze My Tesla And Immediately Plugged It Into A Supercharger To See What Happens

in the morning and then I get boom, a big brick of power, let's jump in and see how it works, it's very interesting, so we're going to charge 26 kilowatts and the battery still has the snowflake, interestingly, so it took about four kilowatt hours of waste heat to start this, to start charging, very, very cool, yeah. The Model X guy, I think it was Jason, super nice guy. I was really curious to see how long it was going to take, but it's actually not as long as I thought. After half an hour, I said, "Oh, it's going to be." another hour yeah I think we're going to estimate the time but roughly around 45 minutes 45 minutes something like that to start charging slowly I don't know so I guess let's charge up to 90 and see how long it takes from here and I feel like a lot of Tesla owners, especially new owners, seem to supercharge their cars to 90, this is obviously a slightly smaller degraded battery than new cars, but let's see how long it takes to get to 90 and then we will do more experiments with it.

I'm going back to the However, Rivian and we can get into Tesla. Well, I analyzed the full load curve here, so I don't need to analyze it on the car. It's freezing and I want to keep the climate control off as a signal to science. Let's get back to the Rivian aspect. listen how squeaky this is, even the Creeks are crazy now, about an hour and 10 minutes into the charging session, maybe a little more than that hour 15 somewhere around there we are at a state of charge of 70 , the blue snowflake has gone away, so it's a true state of charge of 70 and it's generating about 50,152 kilowatts, which is not far off from

what

it would normally do.

Typically, we taper off a perfectly normal load curve down to 50 kilowatts by the time we reach about 80 states of charge. charging, so it definitely warmed up pretty well during all of this again, it's just colder outside it's about minus 16 degrees Fahrenheit according to the watch on my wrist here, incredibly cold and very impressed with how quickly this thing can heat up the battery, there's One last note I wanted to make about battery warm-up is that you can only charge as fast as the coldest item or the coldest part of your backpack when we're on the right track, when we do a lot of DC charging, of which We always talk. something called hot spotting of the battery pack and technically you can't cool every part of the battery pack and you can't have sensors on every part of the battery pack so there's a lot of computer modeling being done on

what

the actual temperature. on the battery, that's a little scary because you really have to make sure those models are perfect so you don't overheat or let your car charge with a battery that's too cold and Tesla is probably better at monitoring and modeling all of this. stuff more than almost anyone else, it's pretty crazy how hard they push it to the limit here compared to every other automaker and guess what they do it with very high reliability, it's impressive, but you know, something I don't really do We think it's cold. detect heater can't touch every cell, every part of the battery pack nor can it heat every side of every cell, so there's a lot of modeling going on here, computers are working hard to figure out what's the coldest. part of the battery pack and what's the maximum power we can put in for that colder temperature because you're only as strong as your weakest link, something like that at least is the saying, so we're pretty close to 90, we'll let that continue and then We will go home and analyze the complete data.

I hope you're enjoying it. I love it. We are approaching the end of our charge as the Tesla T begins to pull slower, it means we are getting closer. finishing up and there we are 89 state of charge wow it's so cold in here kept getting off the heated seats they actually stayed off so they're just coming back on but since only one person will be driving we'll do that we'll add 37 kilowatt hours uh Again, that's from the charger to the battery pack, we'll have to look to see how much testimony believes it used to heat the battery.

Interestingly, the temperature here A load has increased significantly, it is well below one degree Fahrenheit ambient, underneath is a cube of ice. in this car, so come on honey, there's only a couple more seconds left, we're going to fully charge, little, we can't charge, unplug and try again, that makes sense because we've completed the charge, okay, next time we sail to the

supercharger

, the battery will be a precondition for faster charging. Well, let's put some juice into this. I'm going to heat it up on high heat because screw it and we're about to do some more experiments.

In fact, it's interesting that he turned red, didn't like it completely and I said, "Oh, he was hot if you don't know." What's up with that thing called the cable? It's crazy, so we go to Colton's store. Let's perform some more experiments. Let me see what Alyssa wants to do, which one she wants to drive, but either way I'll see you back. at home and we will analyze the data from this super fun experiment, very interestingly, we actually have no power limit on regeneration or acceleration, this thing is ready to go, the engines are probably very hot after running on waste heat for so long time.

I'm going to scan my Tesla. I actually lost my adapter because it's sadly on and I'll have to get a new one. What am I trying to do in this one track mode? Let's see that the engine is warm. Yes, look what the engine has. warm in the back burning off all that residual heat, that's funny, I thought that would be the case, let's turn off the track mode and get back to driving, which you can barely see anything about, let's put the rear defroster on, okay, let's rock and roll let's roll, so I just left the

supercharger

on and you can see minus 14 degrees Fahrenheit.

There is a super cold cold. Mine is 15. It's going down and down as we drive. Wow, these are not easy conditions for this car to perform in and I must say it took a while. Yes, but there's also a lot of thermal mass you have to heat up, so overall it's pretty impressive. Then, of course, you can ship a Model 3 wherever you want. It's very easy, I love having track mode if you want to have fun. I love this car. So there goes the Model 3

deep

freeze experiment. I know some people will take this video and say, Oh, Teslas don't charge in the cold and unfortunately there's no way around it for our power users, most of them. you.

I'll understand, if you're on a road trip and you precondition your car with a supercharger, no problem, everything is vertically integrated, it works great again. I left the car on the charger for two days to turn it into an ice cube two. full days and then plug it directly into fast charging just to see what would happen, something that will pretty much never happen in the real world. I'm sure there are some cases where the car can handle it easily, you just have to wait. to charge up some power and again, it's always a test if you're on a road trip and it's really cold, charge the night before if you want to wake up and go.

Actually, what I usually do on road trips is leave the car at around 40 50 state of charge and then in the morning, before I get up and shower, I run out in my underwear. Not really, but that would be kind of funny. Plug the car into a supercharger. Works. The battery gets hot. up to 90 95 percent, it's not in a high state of charge and everything is nice and warm for a very efficient stretch on the next stretch, it works very well. I do this quite often on road trips that have hotel superchargers, so there you have it, thanks for watching another out of spec review video.

I thought this was fascinating. I'd be very curious to see how other cars handle this kind of logic, so I'm actually doing one with a Nissan Leaf, uh, two Nissan Leafs, one broken, that's a Next video we also have the model 3 PTC heater race uh versus heat pump in the next few days we did a lot of tests in cold weather, so thank you very much for watching, see you soon in another one, bye.
