Electric Car Batteries! Myth Busting & How Long Will They Last?

Feb 27, 2020
Hi guys, I'm EVM and welcome back. Today I want to talk about

electric

car

batteries

because there is a monumental amount of misinformation, disinformation, half-truths and outright lies that make it very difficult for anyone who wants to buy an Eevee. With confidence in this video, I hope to dispel those

myth

s so you can buy an Eevee without worrying about the things that well, let's face it, things like the Daily Mail constantly insist that it's not only twisting the truth, it's completely wrong. An example of this is the almost daily comment I receive from people saying that

batteries

need to be replaced every two or three years.

Let's face it, I sometimes talk to these people who listen to

electric

cows for reasons I can't understand even though I've never sat in one let alone sit in one. It's like talking to a flat earther and trying to persuade them that the Earth isn't really flat. Anyway, that's what this video is about, to try to point people in the right direction when asking these questions. And comments appear, so if you're thinking about buying an Eevee and you're worried about the batteries, then don't be and hopefully this video

will

dispel some of those fears. Let's get to that with what's actually inside an electric battery because, again.

More Interesting Facts About,

electric car batteries myth busting how long will they last...

There are several things that I think people don't know. The first is that there is not just one battery in a battery powered electric calf, if you are thinking it is something like this, which is an iPhone battery, but there is no larger version. Generally, there are many batteries in an electric car, for example, my leaf outside is a 32 hour leaf that is almost four years old and now has 192 cells, so it is not just one big battery, but many batteries, which which has significant advantages that Throughout this video, I'll get to another thing worth noting is that

they

are much more advanced than what people traditionally consider batteries, so, for example, this is not the same as what that you would get in an electric vehicle.

Much more advanced, another thing that electric vehicles have over typical consumer items anywhere is a battery management system, that's what it sounds like, but BMS is its job is to simply look for the batteries. I'm not sure how much clearer it can be. I

will

do that. I'll give you an example of this rather than all the examples of why it actually does it, but this will give you an idea of ​​what the BMS does and why it's good for battery

long

evity. Now that we all know how to completely drain a battery it doesn't. They don't do them any favors,

they

don't like to be completely drained, on the other hand they don't want to be fully charged or 100% as it can reduce their lifespan, so what a battery management system will do is prevent that. happen.
electric car batteries myth busting how long will they last
Let's take my leaf out again as an example. Nissan is a bit naughty with this because they advertise it as a 30 kilowatt hour blade, in reality it's about 27 kilowatt hours and a half of usable battery and that's because they reserved one type. of a shock absorber on the top of the battery and a shock absorber on the bottom of the battery to prevent it from being fully charged to prevent it from being completely drained, for example if I drive my blade until it literally stops, it's a zero percent stops running and the car says it's at zero percent, actually that battery is actually about four five percent, that's done just to protect the battery from completely draining or should I say, and in it it protects it basically helps its

long

evity and, at the same time, On the other hand, if I charge it up to 100%, the lot is not actually at 100%, it is probably at ninety-five ninety-six percent .
Now some cars are bigger shock absorbers than others, but ultimately that's just one example of many things the RBMS, a battery management system, does. to protect them so they

last

longer than things like this something else they have that again adds longevity and protects them but not all Vs have this is battery thermal management now Mike Lee for example doesn't have active battery thermal management lots at all. Cars like Tesla's, for example, which most people are familiar with, again have full battery thermal management. Most people recognize that when a battery gets too cold, it reduces its efficiency and can also reduce its lifespan.
On the other hand, if it gets too hot, it will again reduce efficiency and lifespan. What battery thermal management will do is if the battery gets too hot it will cool it down and of course if it gets too cold it will heat it up to maintain a stable temperature range again. to help with battery life like I said not all V's have that Thundra stuff on the back safe cooling to keep them from getting too hot they all have everything and some like my blade don't have no active thermal battery management at Now, all in all, what I'm saying is that once you take into account that you have much more advanced batteries, you have a lot of them, not only do they warn you, you have battery management systems and, somehow, battery thermal management systems.
Don't impose your experience with these things or even these things. iPhone batteries are general batteries and you think that's how it is in an electric vehicle. Ignore this completely. What you think you know about batteries in normal everyday life. It's not what you'll experience in an electric car, so that's something we hope we've clarified. They are a different animal now. Our batteries in an Eevee compared to laptops, phones, cameras, that's our. Now let's move on to a question that is again asked very often. How long do the batteries

last

in an electric jack? But ultimately it is almost impossible to answer precisely.
There are a million variables that affect the lifespan of anything, not just batteries, and I would need more information to give anyone even a vaguely accurate answer. that question is put this way, if I were to ask you how long does a petrol engine last, normally the answer would be which petrol engine and we are talking about a Dutch engine or an engine here or a Mercedes e class engine, are we talking about cow? that he received proper service I wonder if he was abused and no service was ever performed. It offers many short trips, many long trips.
Are you driving very harshly? Do you drive carefully? There are a trillion variables that affect the life of a motor and a battery is no different. Understand me, it's a very broad question that could only be answered very broadly, but I'm going to try it now. What I'm going to try to do is give you two examples of Qasr, right now, today in 2021, at the low end of the battery technology scale and one of the highest, so if we can look at the worst case scenario and the Best case scenario, then it will give us an idea of ​​where we are going, so for this I will choose a Nissan Leaf next.
Tesla Model S just because both have been out for quite some time, the leaf has a less advanced system, should we say battery management nor battery thermal management in terms of active anyway, where is the Tesla that is considered so-so as the pinnacle of battery technology right now, how they take care of their batteries so that's the top spot. Let's look at what you're going to get roughly out of a Leaf and a Model S. Now quickly answer the question that you need to replace your batteries every two to three years I can debunk that right away because well let's take the Nissan Leaf, my Nissan Leaf for example, It's 2016, 30 kilowatt hours and comes with the battery with a hundred thousand mile eight-speed warranty.
Now I know that manufacturers are not stupid when it comes to it. to money and they are not going to guarantee something that needs its place two or three times during that guarantee period, which will ultimately end up costing them a fortune. If they did, of course, they wouldn't let me be clear now. I just said that you will get a seven or eight year warranty on all cows currently sold in the UK, depending on the manufacturer. Swimmer Seven somewhere around eight years old, but that doesn't mean you need to replace the batteries after seven or eight years.
It's another thing, people I don't know, don't listen to what you say, just like you wouldn't replace a gasoline engine when the warranty is up, you don't replace the batteries in an Eevee when the warranty is up in terms of the Misun Warranty sheet and status minimum health of 70% after that period of eight years or one hundred thousand miles now listen look at my lips minimum now again Nissan is not going to want to take risks with this and end up paying money Nita or that, so if they think it will be a minimum of 70% after that period, it will actually be at least 75% minimum now, if we look at 75% minimum, I would say the upper end of that scale would be around 85% after that period, so which between 85 and 75 percent, which gives us a rough average of about 80 percent of the state of health in an average kiln on sheets over eight years or a hundred thousand miles, of course, that's what they They call it an average. so it will be higher, some will be lower now let me pause for a second and leave the Nissan Leaf which, what we just said, I'll look at what happens after 100,000 miles eight years in a minute, but now I want to look at the model Tesla.
S and see what kind of annual battery health you would get after a similar period, now given that it is three times more expensive than a Nissan Leaf you would expect much better health. Teslas are again known for their longevity and care. their batteries are doing great and fortunately, because they've been dead for so long, there's now a lot of data available to save me from having to do my own charts and all sorts of things. I'm taking this from a variety of sources it comes from. the very good Electric website, so this, for example, is real data from the Tesla Model S and X over 250,000 kilometers, as you can see in this graph, the red line is the average of all of them and all the points of the individual cars and what this basically says. us is that after 205 2000 kilometers you still have about 92 percent on average battery health battery degradation less than 10 percent after more than one hundred and sixty thousand miles console, the batteries in this theater will only get better every time more over time, now this other graph here again shows 250 thousand kilometers and on the side you can see that the battery goes from 85 to 100 percent health and you see that there is a small drop at the beginning and then it stabilizes, but more than 100 and there were 60,000. miles, I think you still have more than 90 percent battery health, so even if we don't reduce it and say you only get 90 percent after that period, you can see that there is a clear difference between a Tesla and a Nissan Leaf.
I guess what you get out of this is that you get what you pay for, but after 100,000 miles and this on the sheet it's about 80, maybe 82 percent actually and being a little harsh on these figures, while a Tesla and a Model S or an The first thing you should know is what car we are talking about. about here this graph from a very good website called geotab. They have a great blog that gives you a lot of detail and reports on 6,000 electric vehicles of very different combinations and models, unless they are health vehicles and things like that, so it's a great place to get information. for videos like this that you now see and they were making graphs to show you that this is the battery degradation of the 2015 sheet compared to a 2015 Tesla Model S, you can see a clear difference there, the staff at one percent and the blade declines at a faster rate than the Tesla is obviously less than five years old because it is a 2015 Karen Ronnie in 2020.
That is why again it is very difficult to answer this question because the cars have not been available long enough to give us a definitive answer and that brings us to Another thing that is different with v's compared to a gas engine car, generally with a gas engine, although you lose efficiency, you will end up with a car that runs, that runs, that runs gently and then just stops working, there will be a component failure which means the engine is simply dead or it's just cheap to repair, that's what usually happens, obviously some people repair it, others might Doing it themselves are the exceptions, but generally speaking, it comes to a point with an old car, we've all had it. where something goes and you think it's not worth fixing then there is a definite end point with a petrol engine car there or you can say it will last about as long before a major component failure occurs in all the batteries, so that's a little bit more difficult because you don't get akind of work curve and then it just stops, you just get degradation degradation degradation degradation degradation of course, the mortars and things can confirm our batteries now, so I guess it's a case of how are you class, where is the end point where becomes usable, take someone who needs 100 miles and range for their life, says 100 miles is trendy, not for me, and ends up getting a car with a 200 mile range, they might have 50 percent degradation of range. battery before it affects its useful life. before it becomes unusable, the person with the car with a 200-mile range that now only has a 100-mile range due to 50 percent degradation wouldn't get rid of it, they'd sell it to someone who, oh Yes, keeping your mouth shut is more than enough.
For me, I only need 50 miles, so you understand, it is very difficult to determine where an Eevee stops being usable or useful because what could be unusable for you or me could be useful for someone else, obviously, because don't go out like nothing It is very difficult to say that they are separated if someone puts a gun to my head and says I want you to give me a long-term projection for a sheet that you have done in this video and the Model How long will they last? I would probably predict that a 2015 blade in this circumstance would reach that sixty percent degradation point between 175 and 200 thousand miles.
That's my estimate, time will tell in terms of age because obviously some people make more. miles than others, so I estimate that between ten and twelve years before the blade reaches that point you cannot predict the future and that is quite difficult, but given the eighty percent probability after 100,000 miles or eight years, I would say that that's about right for me something like a Nissan Leaf so 175 to 200k miles again on average someone much more than that some will be less than that I think I'm going to choose that one and the same for years 10 to 12 now when we look at the Tesla Model S, well, there are a million examples of hello, mine was available for you.
I could have chosen tunes, however what I would probably say with 100% certainty is that in terms of batteries alone, a Tesla's battery will last considerably longer than the cat. There are tons. of people with hundreds of thousands of miles on there, I think they are the gang with the highest mileage, Tesla, the one with 550 thousand miles and that's on the original battery, not sure about the mortars, but it's about batteries , his definitive effect said that Batteries will never be a concern in something like a Tesla in a sheet, depending on how old it is when you get it or how long you keep your cars, but I think between one hundred and seventy-five and two hundred thousand miles avocado is enough.
It's not that bad and again it doesn't stop running, it just means it doesn't have as much range, but the last time I found out what the average lifespan of a typical petrol car was, the RAC said it was around 12 , 12 and a half years old. Obviously some of them will last a year before they tear them apart and tell you some of them will last 20 years and that's how you end up with an average and I think what we can take away from this is that if you buy a lower priced electric vehicle, it clearly won't last as long as a high-end electric vehicle.
You get what you pay for in life. I guess for that reason I'll leave the stats available and leave it up to you if you think it's acceptable. or not, let's move on to what happens if you want to repair those batteries. What if you think you know what you have? 6% degradation. Now I want to keep my car and just get the batteries back to health. This is something that people usually have. How many times people used to tell me that with my old 500 pound blade, our blade, which is a much smaller battery, it's going to cost me five grand to replace the batteries.
I wish I had a nickel for every time I had one of those. comments anyway, ultimately this is something that will happen, it's not true and it's for this reason let me give you another example, let's say you have an old car 15, you know, Volkswagen Golf and the engines just disappeared, you need an engine new, what? What happened is hello mister Volkswagen, yes, my Volkswagen Golf GTI's engines broke down, it's 15 years old, so could you try swapping in a new engine? Please quote full retail price. See that doesn't happen. Don't people replace an old engine? I entered the real world with a new one from the dealer, what normally happens and we all know is that you will look for a used engine or maybe a reconditioned engine and put it back into operation that way.
Can't. Think of just one person, although I'm sure there is someone, certainly in the comments section, who bought a new engine from a main dealer because their engine is gone, at least when it's out of warranty, it's anyway an old car and the same would be said for an electric vehicle for one you know there are many lots not just one so you would only replace the cells that needed to be replaced so if 40% of the cells had a failure you would replace 40% of the battery. not the entire battery pack, so no one is going to have an old electric vehicle and then buy a battery pack at full retail price from a dealer and replace the entire battery even or only half needs to be replaced, which in The reality that will happen and is happening now is that they will go to a third party or independent battery specialist (there are many popping up all over the country right now) and they will remove your old battery and put a reconditioned battery in its place in the entire battery pack. .
I mean, then they probably will. recondition your back and someone else will understand, so that doesn't really happen, people won't go to Sun with a 15 year old Nissan Leaf and say here you fix it, fix it for me, charge me whatever you want, let's be real. Someone from the Daily Mail who writes these types of articles will call Nissan and say how much a new battery costs, even though in 15 years it will be much cheaper. How much does a new battery cost? Oh, that's five thousand pounds for the eyes. I will say that in my article it doesn't make sense, just as it wouldn't make sense to find a new Golf GTI engine, that's how much you have to spend after 10-15 years of owning a Golf GTI for you to get what I have.
I'm saying here that a replacement wouldn't be the entire battery, it'll just be the way it needed it and you wouldn't go to a main dealer anyway and you wouldn't want to go to that limit. It should also be noted that looking at a 10 year old electric car today is not indicative of what a car today will look like in 10 years the battery technology is advancing, I mean it's advancing year after year so a cat today will pass the technical inspection it will last longer and more advanced than the car from 10 years ago, of course, just like a gasoline engine, it becomes more efficient, the place they go in, the better they are designed, the same can be said of electric vehicles, so when we get to you, we will know in 15 or 20 years. who knows where we will be if solid state batteries become a thing and a lot of people think it will work, even some manufacturers claim that they have already figured it out and that will change everything completely, but that's for another video and anyway, hopefully. this has explained a bit more about EV batteries in a non-technical sense of course at the end of the day I am NOT a battery specialist I am NOT an engineer so take everything with a pinch of salt YouTube just do it especially if it's in the mainstream media as well, but I've tried to back up everything I've said here with at least some evidence and I trust that the assumptions I made here are correct now, of course, if I'm wrong about something, I'm I'm sure people have already told me that in the comments 14 million times so I apologize for that but fingers crossed I haven't so yeah since this lady is scared since she made you think.
Oh actually, yes, my look at battery powered cars now I did. I think in the last 2 or 3 years, but now I'm no better because she made you think well, look, they know and I'm still not convinced. Let me know that's what the comments are for, but be polite, that's all I ask. I don't care about questions, I don't care about opposing opinions and as long as he goes back to eating somewhere just saying that electricity sucks and unless you can drive 800 miles on a single charge I'm not interested, that doesn't help . anyone does I mean, I love coming unless he can go 800 miles.
I'm not in I don't want one. It is very common for people to drive from Land's End to John O'Groats for a 15 to 18 hour journey without stopping at all. That happens all the time, doesn't it? As always, thanks for watching, subscribe, help and if you want to buy some work, go to Lovely Merch, calm for/even everything. I'm in the description below, thanks for looking. and I will see you soon
