Model Y E32: High Voltage Battery Comparison - Cylindrical vs. Prizmatic vs. Pouch

Well here we are again boys and girls, another day, another

battery

, so let's take a look at this

battery

pack. This is the Tesla Model 3 battery pack and I wanted you to take a look at it because here we go. What we're going to talk about today is battery packs in general and I want to show you that this battery pack is very similar to the

model

. Why the battery pack you can see here that there are three of the three battery packs that are here or three of the The batteries are here, but one is missing and that one is going to discharge and we're going to have some fun with it, let's to take and do basically what we've done here and that is take some of these. cells to make sure they are the same as what Tesla used before, so there have been a lot of questions about how this works and what doesn't, so I'll try to tell you a little bit about this, but essentially what you have is a bunch of these tiny little cells, there are four thousand four hundred and sixteen of those little bugs in each of these bars, this is called a brick and this brick goes on top of more than On the top of these cells and on the inside, if you look very closely here, you will see small aluminum wires that are attached with cables to the back of the collector, so this collector will connect 46 cells and when connected. when they're all connected that way, Tesla calls it a brick, then the bricks that give you parallel and then for series, they're placed on top so you can see we've removed some of them and then you see these other ones. the ones that go in a different direction and are the pickers that give you all the connection to the hitter so let's move on here and take a look at what cools this down so first of all these things are all. glued together it's not easy to get them out there's a lot of things you have to do to make this happen and we're going to make a video of me cutting one of these things on the new

model

why battery One thing I forgot to say is that there are 96 bricks in a battery, so the entire battery will have 96 of these things and that's what connects the cells of the 4416 batteries, so the other thing is what is the chemistry associated with this well that we have. chemistry for everything but most people are really interested in their Tesla and the Tesla is nickel, cobalt and aluminum of course the main ingredient is still the felicium ion but that part is the main product but the rest It is the nickel of cobalt and aluminum.

So we've talked a little bit about how these things are

cylindrical

, but they're not the first or the only ones. These are the first types of batteries that we originally started to see. In fact, I think by the early 2000s, they were no longer available. a Ford product, in a sense, has taken a different approach, so now that we've talked a little bit about Tesla, let's talk a little bit about its competitors, so this is called a prismatic battery, so what you have here is a bunch of These different packages that are made and glued inside this tray and then soldered closed so that in the end they look a lot like this system is pretty cool, but the problem is that it has to have a box around it to hold it together, so so that Tesla is all glued together with conductive glues and with the cooling system it is shaped like a piece of lasagna, all glued together so that they can dissipate the heat that these BMW guys have used. something a little different, so the original was this is an electric heater basically for when the battery is cold and then this with the micro channels similar to what Tesla did, these micro channels had coolant as a coolant like in your refrigerator or or better yet in your car, so these two things were placed on top of each other like this and then the battery pack was placed on top of that.

This is an old style. Many people have gone and taken this one step further. This is Samsung's idea, so these guys. here this is LG and this is what's in the Chevy bolt so the Chevy bolt uses something a little different they're called bag cells the bag basically fits inside here and you'll see there's a little trailing edge on these and what They are folded in a serpentine shape so that each bag is connected to the bag next to it, so when you look at it when you finish looking at this, you find that this is the most expensive way to make the individual. cells, this comes in second for being a little less expensive, but they are cheap.

You can make thousands of gelatin batteries in a very short period of time. These take much longer. This takes longer to develop. the pack itself, but it's the most efficient when it comes to space and weight, you get better density here. Another thing that's good is that I told you that these connector plates here, these collector plates. I must say that they are made up of brick. What if? one or two of these little connections are no longer connecting well each of these little 2170 batteries is three and a half volts and three and a half volts if you lose one or two it's not a big deal.

Wow, the component underneath them. white and orange covers that are for battery management and that will balance the batteries for the little differences that there would be if one of these cells decided to die or if one of these little wires somehow broke when we did. the balance on this, the difference was minuscule, it's the smallest differential we've ever seen. We hope to see the same thing when we do the testing with these batteries here and then the last one, like I said, is the Chevy Volt, this is LG, the chemistry of LG has changed quite a bit and a lot of people are using LG batteries now, it's like the favorite group which is on the market right now, so that's Panasonic's design, but LG and Samsung also make

cylindrical

batteries. and this is the BMW of the idea, but Panasonic also makes binoculars and bags, so the big three companies are working together or working with each other, but they are all trying to come up with new chemistry and new ways of presenting their products so that they can reduce your costs so last time someone asked what these things look like so this is a 21 70 cell and as you can see it's corroding and that's just because it's in the open atmosphere it will never do that when it's inside that plastic brick that you saw there, that's why we have this here, this mineral oil, by the way, I just found out that this is a lubricant and a laxative, how about that? helps relieve occasional constipation tasteless odorless colorless blah blah so you can keep your batteries from catching fire or you can drink it if you have a problem so now let's see what we can do to sell some things first of all this is the table

high

and I know Mother's Day is coming up, so all the mothers, I'm sure you would love to have one of the tables, but I know the best gift might be one of these batteries, okay? and two of them. those two will probably be on sale, they're not for everyone, they'll be sold to OMS or tier one suppliers and they're pretty expensive, so I'm sure you could buy one of these things for your favorite mom, but in this case probably I'll reserve them for OEMs or

high

-end companies anyway, boys and girls, have a great day, remember to tip the cashiers and let's all be safe. there thanks and goodbye
