Another growth in battery usage is in homes with solar or for load transferring and backup. Prices continue to fall for this application. Thanks for another great video.
My Model 3 does not have as steep a change in range as my i3. One morning last week, it was chilly, and the i3 said 99 miles. An few hours later, the temperature had risen to 10 Celsius, and the i3 changed to 138 miles, and this was after I'd done the school run.
Thank you for sharing! I'm curious about statistics on this, which I can't find a lot of. I think despite the late shift from PTC to heat pumps in 2021, Tesla has always had really good battery temperature management. 🙏
Surely you're aware that an air conditioner is a heat pump, so any vehicle, electric or not, with AC, has all the necessary components to heat the cabin without resistive heating or waste heat from combustion. The only difference is in the valving and controls.
Absolutely. They've had a one way heat pump to cool the cabin. Now, they are using heat pumps to manage the battery temperature as well. Thank you for watching and sharing your thoughts. 😀
It would be reasonable, then, to conclude, where a heat pump is unavailable, that vehicle makers are being especially lazy. Where it's available at additional cost, it would appear to be a basic money-grab.
Considering that Tesla's 2nd largest market from the very early days of the Model S was Norway, the fact they took so long to implement a heat pump is puzzling.
They used PTC heaters instead until 2021. Heat pumps are of course much better than radiators. There is a lot of design that goes into good battery temperature management.
@@NetZeroTech Yes but PTC heating diminshes range and if you start off with a cold battery on a cold day it's a double whammy as you need to warm up the battery and the cabin or, at the very least, the driver's seat, at the same time. Waiting until 2021, by which point Model S was nearly 10 years old was astonishing for a car in the premium / luxury segment. Even more so when Elon made such a big deal about how much better Tesla air filtration is than the competition, with the intro of BioWeapon Defense Mode - *in 2016*
Indeed. Great points. They paved the way working with the legislation to get EVs on the road, however. So, they have done some heavy-lifting pioneer work, too.
Thanks, Katha, my 2024 Ioniq 6 has a heat pump (bought for 38K in Winston-Salem, North Carolina USA). To my knowledge, heat pumps are standard as of 2023 on Ioniq 5 and 6. Our Rivian R1T does not have a heat pump.
Hi Diane, Thank you for stopping by and leaving a comment! Congratulations on the heat pump in the Ioniq 6. That's awesome! Interesting that the Rivian doesn't have one. It'll probably come around sooner or later. I used to own a Hyundai Ioniq Electric in Germany and loved it. Sold it to my parents when we moved to the US. They really like it too. Cheers, Katha
@@NetZeroTech Yes, I LOVE my Ioniq 6. Yes, supposedly Rivians are going to have heat pumps in the future. The heat pump in my Ioniq 6 does take up the whole frunk pretty much but I don't mind. That could bother some buyers because North Carolina is mostly a warm climate.
Thanks for pointing out the importance of heat pumps in BEVs. I just hope that nobody will be misled to believe that the existence of a heat pump makes a Tesla a good car. I bought a Model 3 two years ago, and it's the worst investment I've ever made. The lack of Apple CarPlay and the insane amount of software bugs in Tesla's system regularly infuriates me. I'll get rid of the Tesla as soon as the new car I want will be available in a few weeks.
Thank you! Great points, @macproduktiv. Much appreciated. I agree that Tesla has its drawbacks. I always wondered, if the price was living up to the value. They are becoming affordable with the rebates. I actually like my 2012 Nissan Leaf better than our 2022 Tesla Model Y. Great value for the price. ;-)
Thanks for that video! A video about the climate control heatpump and whyit is even an option to not use this already existink piece of kit to teat the cabin would be great. this is the "Why dont they just..." question in my mind on this topic everytimes.
Thank you so much for watching and sharing your thoughts! 🙏 I actually thought along the same lines producing the video. I imagine the design of thermal management, whether battery or cabin is complex. Perhaps, they don't want to change too many variables at ones and we see it in the coming models. Have a great time! 😀 Katha
"Do Heat Pumps in EVs really matter?" - "No matter how highly mechanised and fossil fuels self-powered, fossil fuels extraction requires a number of people - as if the process is executed by hands using buckets and ropes". Today, this number is 8 billion people - working flat out 24/7 - strong. Katha, you and I are among those, too. Our Western Civilisation has been no more than a fossil fuels extraction operation - all along. Finite fossil fuels are dangerously hypnotic to humans, their consciousness, reasoning and mental capacity. Humans were not ready morally, ethically and intellectually to start the mass extraction of fossil fuels with the advent of the steam engine 300 years ago. The Magna Carta requires today overhauling - adding to it the right for humans to understand what Energy really is - before any other commandment. "In any system of energy, Control is what consumes energy the most. No energy store holds enough energy to extract an amount of energy equal to the total energy it stores. No system of energy can deliver sum useful energy in excess of the total energy put into constructing it. This universal truth applies to all systems. Energy, like time, flows from past to future" (2017).
Apologies. I have been working on this. I hope the more recent videos are better. I have limited capacity, because I have three kids and am still doing everything myself. I hope I'm learning fast enough to keep you here. Thanks, Katha

@@user-oe9pv8yq8y Thanks for leaving a comment. Anything in particular that I can improve on?
Hi NetZeroTech. Fantastic video. Improving audio quality will bring it to the next level :)
Hi Keith, Thank you so much! Your feedback is very helpful. 🙏
The heat pump is useful when driving for more than ~ 30 min ? Correct ? Thank you !
Great question! It is useful right away. Thank you for sharing!

@@kevinhoward8410 Or building bidirectional heat pumps for a EV's battery and cabin temperature management simply isn't that simple. 😀

@@dianewallace6064 Interesting. Thank you for sharing!
@@NetZeroTech When Rivian's get a heat pump, their frunk space will be much reduced. That is a trade off but worth it to me.

Is this AI generated? the death stare gives me goosebumps..she doesn't blink.

Oh, and no, there is no AI involved. If there will be, I'll let you know.
this lady blinks only once every 30 seconds
