Tesla Model S EV Battery

battery pack overview. So, this is a Tesla Model S 85 kWh battery pack. So, a lot of people think, “Oh, it’s just one big battery.” It’s actually not the truth. So, here you have [music] 16 individual modules throughout the battery pack. In each module, you have cells. So, [music] each module has 444 cells. Times that by 16, according to my calculations, that’s 7,14 [music] cells inside of the whole battery pack itself. And although they kind of look similar like a 75 and and 85, a 90 and 100, [music] there are a few small differences. So imagine you and your friend, you both own, let’s say, Tesla Model S, but one of you owns a 75 kWh and another owns 100 kow battery pack. The price [music] range for the battery is going to be drastically different, but it’s not going to be drastically expensive if you take the tip that we give you at the end of the video. But while we’re here, let’s talk about each individual module itself. So, as I said, 444 cells, and [music] you’re going to have the temperature sensor right here, which manages the temperature of the battery. And the cool thing is is a lot [music] of batteries just have one big BMS. Tesla did it very differently. So, each module has a BMB, which communicates to the battery itself and [music] measures voltage and the temperature of the battery, which communicates to the big motherboard, the [music] BMS. So, I’m going to say that one more time. You have BMBBS on the module and you have the BMS which collects all of the data overall. So there are companies that do like EV repair or Tesla [music] repair. The problem with that is what they do is like okay they’ll say this module is bad. Let’s just go ahead and replace that, right? Let’s just go ahead and put a band-aid on my broken arm, but that’s not a solution. Sometimes you need surgery [music] as you can tell, right? So you want to look for a company that is fixing the common problems in all the modules. And you want a company that doesn’t just pass over the small stuff. Make sure they do the following things. Number one, corroded capacitors on the BMS. The [music] protective coating wears down, allowing moisture damage. Number two, voltage tab corrosion. Tabs can [music] break loose, requiring specialized repair equipment. Number three, faulty umbrella valves allow moisture inside, which can trigger [music] the above failures. Okay. And look at these cool black things that go all along through the battery. And as you can tell, if you look inside, they actually go inside the module. Well, what Jack, why did they go inside the module? Let me inform you. Okay, so what this is actually doing is it’s cooling down the battery. So yes, you’re sending liquid [music] inside of the module itself. And it can either be warm or cool. [music] It’s called cool lint, right? Cool lint goes through the full battery itself to make [music] sure everything’s a good temperature because batteries fail in the heat. They overheat. So for a Prius, [music] for example, you’re going to have a fan and the fan cools it down. They don’t have coolant flow. But for EVs, [music] especially Teslas, they made it a lot more advanced where cooling is an easy accessible system. So, we’re definitely not paying Tesla $20,000. But let me tell you when looking [music] for a company, what to look for. So, as I said before, you want to find someone that fixes and maybe even write this down, the common problems in all of the modules, right? You don’t just have sales, you have temperature senses, you have a BMV. There’s so many different components, right? That’s number one. Number two, don’t find [music] a company that just repairs or replaces one module. find a company that takes all of the modules out and cycle tests the modules [music] to make sure the capacity is balanced throughout the whole battery. So, my biggest concern is I live in an apartment complex. So, I wanted to find a battery replacement company that could still enable me to supercharge. I read a ton of stuff online says, “Oh, you can’t supercharge when you get your battery placed from an aftermarket company.” And that is true for most aftermarket [music] or repair companies. But I did find a solution that I’ll tell you about at the end of the video. But also something interesting [music] is you can also upgrade your battery. So if you have a 75, you can upgrade to an 85 to a 90 to 100 kilowatt [music] hour pack, which not just increases the kilowatt hours, you’re increasing the range of your car itself. You could increase the performance of the car itself, but also you’re decreasing [music] the amount of charging time it takes. So basically for the installation itself, it’s actually pretty simple. What [music] they do is they take this car up, they put it on the lift, they lift it all the way up, and then they drop the battery um outside of the bottom of the car, they put it away, do whatever they do with the battery, and they grab a new battery, the one that I’m getting, and they put it inside of the car. And then that’s basically it for the battery part. But then they have to program the new battery to the car. [music] For example, mine’s an 85 kWh. I wanted to upgrade to 100 kowatt hour cuz I kind [music] of wanted some more range. So the computer has to understand how much range it’s getting, right? So they have to program [music] the new battery to the car and then also what Green Tech does is they also cycle test the car which they take it on [music] two to three full charging cycles to make sure it’s actually getting that range. Yeah. So I did promise you that we would tell you something that’s going to save you, you know, up to 50%. And I [music] do keep my promises. So we’re going to get to that right now. The company I work for, Green Tech Auto, some of you who’ve been looking at me have been probably seeing this on my shoot like what does Green Tech Auto do? So we’ve been specializing in hybrid Navy B replacement since 2012. So that’s basically over 13 years of specialized experience in this business. We started off with Priuses, [music] simple batteries like that. But now, as you can tell, we have over 240 different types of batteries all around our warehouse that we sell. We have Tesla Model S’s, Tesla Model 3s working all day long. And if you click the link in our bio, greencheck.com, you’ll see all the different models of batteries we replace, different kilowatt hour batteries, and also if you own like a Model 3, you could see standard, longrange performance, whatever it is. And we have 34 locations across the United States where you can come by, get the installation done in a matter of no time. So, hope you guys enjoy.
