- There are a lot of myths, misconceptions, and misunderstandings about EV batteries floating around on the internet. That’s why we had a sit down with Polestar Lead Engineer and resident battery expert Camilla Møller to discuss some of the most common ones.
#PolestarCars
I appreciate the video and Camilla did a great job but these questions are like 8 years old and Polestar isnt your entry level EV company so people looking into it very likely already know this stuff. We need more challenging questions about battery degradation, partnerships with charging companies (how/where they get their power), real world range, tips on keeping KW/hr down while driving, ideal range models, future range for newer Polestar models, innovations that we could see soon, and other complex issues. Does the car shock you while driving it? C'mon man
It wasn't me.
So why did I get asked some of these questions while I was charging my car at a supercharger a couple of days ago if everybody already knows 🤷♂️
@@stevec401 because I'm wrong Steve and you saw right through me.. J/k turkey, read my comment instead of being cute. Unless you are a salesperson charging at a space, your comment is irrelevant
The only "electric shock" you'll get from the Polestar 2 is the shock you get when you hit the accelerator and sink into your seat. It feels like your flying the Millenium Falcon.
Actually I can't wash my Polestar 2 in the carwash because of the TCAM sharkfin seal issue, but that is nothing to do with it being a BEV and the same issue is present with the Volvo XC40 (the ICE version). Hopefully polestar will correct this issue shortly.
It's not a big deal for me because I handwash my beauty anyway, so I take great care when washing around the sharkfin.
Polestar sucks....
One thing. I think you could be more honest of battery health with capacity under 20 and over 80% (or under 10 and over 90%). Of course the battery will work, but it's not fine for the battery to stay a longer time in this area. And one thing I think is not correct. You said 20 to 80 is because of charging speed, but less capacity, is more speed. If you are near to 0 % you have a longer fast charging speed than you start charging at 20 %. I am a big fan from the brand.
That is a good question but, with all respect stated in the wrong way. If I’m not mistaken like other brands there a total battery capacity and an usable capacity, there is always a physical reserve to ensure the chemistry fluctuations can be handled. If I’m not mistaken in the 78 it’s 75 usable? Thus resting at 100% is a non-issue cause you have the BMC and the physical buffer. But resting at zero might be less healthy, also there is the reserve capacity again. Can we get an answer to those specific points? As in home slow charging to 100% or staying at 100% or over 80/90 what is the expected result?
Keep up the good work as always Polestar. My #1 and all time favorite vehicle. 😍
First Volvo 2nd PS 🤣
Great video, I love how personal the answer is and how Camilla, is enjoying the questions whilst answering them in a way which instils confidence in her knowledge and comforting for us less knowledgeable about electric vehicle batteries.
How did people send in those questions? Did they text you?
This is a compilation of our frequently asked questions that we've seen within our online Polestar community.
Grateful to polestar for answering these questions 🙏 So many of these questions are the exact arguments that people will make to not drive an EV, so it's great to have an expert explain why these are myths :) The more people who realize these are the future, the more in demand they will be and that will drive (🤭) even greater innovation in the auto industry and in infrastructure 😊
If you listen closely, she does not dispel the "myths".
Funny, and kind of cute, but also feels like trying to distract from the real concerns and challenges of the EV industry.
Yes, batteries CAN be recycled, and I'm sure it is a part of the design to consider how that is made easier, but that doesn't mean there aren't still significant challenges along the way. Currently there is no standard, nor clear solution where or how the batteries are going to be recycled once the currently on the road EVs, or their batteries, come to the end of their life cycle. It's messy, expensive and hazardous. And the car manufacturers don't really seem all that concerned about it. At least I've yet to see a single CEO talk openly and honestly about this.
Polstar, do you think about replacing the battery with hydrogen?
What’s is the recharge lifecycle of the batteries does it get worse over time like mobile phone and laptop batteries?
Will you get reduced capacity or power after five years etc? I think if you are being open and honest as a company you need to talk about the challenges you are facing as well with your battery technology?
These videos should be about answering legitimate questions not addressing statements with no elaboration on your own.
Your brand is great and is the first electric car company I actually want to buy a car from but one thing that irks me when companies make the statement “we rigorously test or we do a lot of testing” annoys me as there is no elaboration at all no expansion on that are we just supposed to take your word.
This video was an initiative created to discuss the most frequently asked questions we received in our social channels about batteries. When it comes to the other questions you have raised, we're happy to answer them!
As for all batteries, the capacity decreases slightly with time and usage. The rate of decrease depends on several factors, such as mileage, age, weather, charge frequency and pattern (charge/discharge cycles), all of which impact the range. Our batteries are designed to last for the lifetime of our cars, and we work with a battery development facility to develop and verify them, which enables us to secure the best reliability, performance and durability.
Also, inside the Polestar 2, thermal control is utilised to cool and heat the battery, which has been designed to secure its longevity. During the batteries' lifecycle, we also have a process to identify and exchange faulty modules, cells, or malfunctions within the battery. The purpose of this is to repair individual modules without having to fully exchange the battery. We're continuously looking into new technologies and collaborations to explore how we can improve our batteries.
We have information on our website regarding the lifecycle, as well as other sustainable practices we follow. You're welcome to take a deep dive on polestar.com/global/sustainability or reach out to us with any other questions to learn more.
These questions feel 10 years old. Let’s talk about future ideas for polestar
Ich habe täglich mit dieser Art Fragen zu tun und beantworte sie immer wieder gerne. Diese Info helfen immer, vielen Dank für das Video!
There should be a question about li-ion batteries. Are there any rumors about newer technology of batteries because li-ion are big pollutants. EV's will be "green" only when breaktough comes on the field of batteries.
Sorry to be the one to break this to you - but - EVs will only be truly 'green' in their entirety, when their drivers are vegan. Otherwise, the argument about EVs not being all that great for the environment as a result of the ecological imprint lithium batteries leave pales, in comparison to the environmental damage done by a non-vegan diet. Animal agriculture is the single greatest contributor to greenhouse emissions (even greater than the global transportation industry) - lithium battery production doesn't even come close. Want your EV to be truly 'green'? Go vegan. Otherwise, you're only kidding yourself with the whole "I'm doing something great for the planet" mantra.
nice
👏🏻👏🏻
As much as I want to say I like this video, I cannot. Repeating words 'rigorous testing' means nothing. At least try explaining how.
Also EVs are fundamentally more dangerous and it is because of the battery pack. But not because of the electricity but because of the weight. But I'm hopeful that both active and passive collision protection has improved in general.
Also, even though EVs dont combust easily, when they do, it happens really quickly and it's almost impossible to extinguish.
And i believe that you cannot really use 100% of your battery, unless the car has a separate battery same way ICE cars have, but it is true that 60% statement is pretty crazy.
Don't get me wrong, i love your brand, but this video is of little value :(
@@Sl1pstreams not necessarily more dangerous to the occupants of the BEV, but more dangerous to the occupants of other vehicles. This is undeniably true because Ke=0.5×mv2. So for any given velocity, a more massive vehicle will have more kinetic energy and thus, possesses more destructive power in a collision with any other object that might be in its path.
@@Sl1pstreams yes it is. I never said it wasn't. It is simply the case that the more massive the vehicle the more dangerous it is. The thing about BEVs is that for an equivalent class vehicle the BEV is significantly heavier, so it is entirely accurate to make a general statement that all else being equal, BEVs are more dangerous than other propulsion technologies.
No one mentioned banning BEVs because they are more dangerous, but it is true that they are.
@@Sl1pstreams I provided the math and the physics explanation of why, for a given class of vehicle, BEVs are more dangerous than vehicles with other powertrains. You're the one who is just denying that fact repetitiously with no facts or explanation. Projection of your own faults, much.
@@Sl1pstreams Last time I checked, BEVs other than Polestar 2 do exist in this world. Both commenters you replied to were talking about BEVs and ICE vehicles in general, so maybe you could also not fixate on P2 a bit?
@@Sl1pstreams all the safety systems that are available for any car, are available for both cars. BEVs do not have an exclusive on AEB or other safety features. I explicitly said "all else being equal" (i.e. the only difference being the powertrain).
The kinetic energy that must be distributed during a collision is greater the more massive a vehicle is. The more energy distributed during a collision, the more damage to all the objects involved. This cannot be argued, because it is a fundamental truth that always applies, all else being equal.
