2021 Tesla Model 3 cold weather testing part 2

Warning! Don't put a bag of hot water near the Ionity charging plug like I did. It could potentially be dangerous or at least make the plug freeze.

Why don't Tesla make a pop up message saying it is heating the battery so normal people (you are special Bjorn) know why it's not charging yet.

[@Amuzic_Earth]

I think Tesla expects people to be either a bit Tech savvy or become Tech savvy by watching others(it's the reason they don't advertise). I mean there are so many clever tricks, easter eggs hidden in Tesla, one has to dig deep to utilize the full potential.

[@gavjlewis]

@@Amuzic_Earth I think most Tesla owners would think "Shit my car won't charge" and start to panic! 😁 Would be super easy for Tesla to add the message.

Lesson learned. Make sure your plastic hot water bag doesn’t leak! This video turned out to be very informative for cold weather charging. Heating the cabin with back seats down is a great tip that can save your bacon.

[@fieldlab4]

Iced up plug. Microwave heating pad might be a better "solution" (solution not liquid 😄). If you commuted in a Tesla in extreme cold to a place without a charger and let the car sit for 8 or 10 hours or overnight I think you would be screwed.

[@kasmopaya2676]

Very interesting, thank you, nice data. Max, afterburner power. I really like to know what a E-tron does with freezing cold battery plugged in, how long till it charges(battery heater is available), or does it charge faster as the competition right from the start again? I remember the good old times with Optimus prime at -38 degrees, max. battery performance and we got max. Supercharger speed right away because the battery was perfectly pre conditioned, with 0 issues on the charging port or anything. A beast! Unbeatable car and charging network. Let's just hope the v3 Superchargers are coming fast. Tesla sharing is not caring.

[@mattaut88]

yeah, have not found out the purpose of sucking heat out and then bringing it back again.

[@kasmopaya2676]

​@@mattaut88 With the Tesla heat pump you have basically more Energy available, without increasing the battery capacity.(very cost-efficient) Very clever and nice. A example: You charge to 100%, precondition the battery as warm as possible at home with the car plugged in. You drive to your favourite camping destination and camp in the car overnight. You arrive with 90% SOC and the battery is still very warm. This heat is now used by Tesla to heat the cabin, therefore needing less energy, till the battery goes down to 5,5 degrees. Normally you would drive way more to recharge and therefore the battery would be warm just because you drive it there, so this is just a worst case example. The other point of heatpump is to save money and the planet. While Supercharging the battery heats up and that heat is not lost now, it's used to heat the cabin. The new cells can take full speed at very low temperatures, very nice for low degradation and charging speed, so not much energy must be put back to heat the battery, most of it is probably coming from the warm motors from the drive anyway. It all makes sense and is very nice. Elon said the heatpump has a live expectancy of about 15 years. So good enough. In Germany we have insane energy prices every little bit helps. Glad that this is standard in every 3/Y now and probably S/X soon. Also bioweapon defence mode is coming to the Berlin Y and heated steering wheel. Just gets better and better with Tesla...

Something similar is already installed in heated seats. You could wrap such a blanket around the chargeplug and power it from a 12V socket inside the car. Maybe it is a nice idea for an aftermarket accessory product? 😉

U can usually tell by if you are moving forward or backwards. And the lights and high beams/low beams are all automatic so even if I wasn't just messing with you and being a smart ass it doesn't seem to be an issue that I've noticed while driving mine.

Wondering if there’s any truth to those rumours about Tesla going to sell home HVAC systems. Apparently they are thinking about using the octovalve technology for this supposedly new system. Would it make sense? Anyway, nice video and looking forward to comparison with e-Niro :) My 2020 model had been very efficient in winter, but of course our winter has not been colder than 1 Celsius... But it has also been very humid and normally in that temp range heat pumps tend to be less efficient because of freezing vaporator. But still getting an average of about 210 Wh/km...

[@kompost1]

8valve is a compact unit for distributing coolant/heat to different recipients with differing requirements. (Eg battery needs cooling, occupants need heat) Sure, their competency in HVAC can be of benefit. But for homes, extreme space saving and multi-flow are not prioritized (my assumption)

Autopilot sees drivable surfaces and can make up lanes like a human driver. That’s why it can also drive on dirt roads. What it doesn’t do is drive differently in snow which needs to be updated!

[@samuelzuffa4298]

Awesome video!

[@marcelbeaucamp9330]

At about 9:38 ‚on the way to Elverum‘ the consumption is >260/270 wh/km 🤔 why was it so high? After 10:00 it is back to 165 wh/km.

[@bjornnyland]

Remember that we have built up kinetic energi in the car: 87 km/h = 24 m/s Kinetic energy = 1/2 * mv² = 1/2 * 2000 kg * (24 m/s)² = 0.576 MJ = 0.16 kWh That energy divided by 4.8 km is: 160 Wh / 4.8 km = 33 Wh/km And there's also an elevation difference between Alvdal (469 m) and that spot (538 m) = 69 m diff The extra potential energy is: U = mgh U = 2000 kg * 9.81 m/s² * 69 m = 1.4 MJ = 0.376 kWh That energy divided by 4.8 km is: 376 Wh / 4.8 km = 78 Wh/km So these two combined is: 78 Wh/km + 33 Wh/km = 111 Wh/km Because the distance is short then the potential energy and kitetic energy makes a bigger impact. As we drive, it will be evened out. And of course, when we slow down, we get the kinetic energy back. And when we descend, we also get the potential energy back. That's how physics works.

[@elektrovelosipedicustomele30]

@@marcel151 it's absolutely true, but the question was about the chemistry difference and the respective cold battery charge algorithm. Tesla would not charge at all if it was left at freezing temperatures with let's say 3 - 5% remaining battery charge and the only charge option is 230V 16A home outlet, because 3KW of heating power would not be enough to warm up the HV battery. That would be scary if there is no faster charge option.

I have a question, and it's probably important: If your battery gets cold, do you lose energy, or do you only lose power? IOW if you re-warm the battery, do you get the same SOC that you had before you chilled the battery?

[@themeach011]

I think just available power but not 100% sure

[@bjornnyland]

You lose power and energy is made unavailable. But once it heats up again, you get back the available energy and also more power.

Thanks for the Video Björn. Amy reason why Super charger deliver more jiuce than the ionity charger?

[@okkeharr]

He explained it in the previous video, The Ionity charger has issues with a temp sensor in the plug.

[@Amuzic_Earth]

He explained it in the previous video, Ionity charger has a sensor that limits it from delivering full power in colder condition. The trick is to heat up the nozzle somehow...according to ionity. If you ask me, it's a shortcoming they need to solve. Lower temperature is actually better for electricals as the resistance is low..meaning more efficiency, so one wouldn't expect the power delivery to be limited. But, my speculation is the low resistance has a potential to overrun some sophisticated electronics in the chip, that usually run on very low power. If you ask me..that's a limitation that they are aware of and can be solved.

​@@lastlondon Did you even watch the video? The faulty sensor was on the Ionity charger not the Model 3, that's why he had to put the hot bag of water on the cable's plug.

[@lastlondon]

@@boostav yes I saw the video, and he alluded to the water bag issue at the end. Not sure what if there is anything to conclude on the supercharger given that there wasn't any water that leaked there, and also Bjorn mentioned there wasn't any moving pieces on the male part of the plugs (on either of the chargers he used, only the receiver has a lock mechanism), so if anything that strongly hints that either some water leaked into the plug on his first charge and froze, or indeed the receiver on the car was frozen from overnight and the hot air in the car that made it into the boot had sufficiently warmed the car after the first charge.

[@boostav]

@@lastlondon It's not hard to understand, the water bag leaked and so the water trickled into the port locking mechanism and froze, which happens very quickly at -24c. That can happen on any car.
