$300 DIY Tesla Powerwall - Solar storage 18650 lithium ion home Battery

Hey guys Jehu, here once again I will show you how to do a DIY project. Today we will see the Tesla Powerwall that has the energy wall. The fact that it is more mounted is vital, I mean, that it is flat against it. Wall and therefore provides you with security and an affordable solution. What is it? Power Wall is a

battery

for your house. Yes, it is a household

battery

. To explain why this is a good idea and how it works, let's watch the video below. A battery for your

home

Why does your

home

need a battery?

A battery can be used as a backup when there is a power outage, like a generator, it can also be used to store energy from

solar

panels, and it can also be used to save money by purchasing electricity at night, when utilities have charging rates. low prices and you have seen the energy stored during the day when the price is highest. Tesla will sell two versions of its electric wall, a seven kilowatt hour version for three thousand US dollars and a 10 kilowatt version for thirty five hundred US dollars, now that we understand what the electric wall does, let's go buy one.

Ah, there's the problem, as I've read, the entire 2016 production is already sold out, that's why today. I'll show you how to make your own. The first thing you need to figure out is what type of batteries you can use. Lead-acid batteries. Those are very heavy and toxic. You don't want them in your garage. You could use some of these nickel metal hydride batteries, but those are the ones that have memory, so if you don't discharge them completely like a full cycle, they stop working and because of memory, this is all technology. a little expensive, they are hard to get, not necessary, you could use

lithium

,

lithium

is the way to go, this is a lithium iron phosphate cell, it is available, they are thin and then you can put them side by side, connect them.

They are lightweight, their power density is quite good, they are quite safe, they are non-toxic, so this is a good option, you can use them today. I won't use them because I have something better. The best I could get would be these guys. This is an 18-6 50. This is exactly what Tesla uses in their car batteries and for the Powerwall. First of all, how do you get these cells on eBay? What you do is buy a laptop with debt. batteries, you take them apart and then you take these cells out, then you test them and stuff, and I have videos that show you exactly how I did it.

I'm going to link them right here so you guys can check them out and watch them later. watch this video and I'll show you exactly how to do that after you sort them and separate the good ones from the bad ones, then what you can do is start putting them together like this brick. The brick here is, you know, a little over a kilowatt of energy and it has 150 cells, all in parallel. This is a big giant 3.7 volt battery. It has a lot of building features. You have a lot of these little fuses here, if any.

If one of these batteries were to die, reverse or short circuit, then that little fuel explodes if it sees more than 6 amps and then keeps the battery safe, that's exactly how Tesla does it and that's how I'm going to build my Power Wall, so I have that video. Go watch it after this video so you can see in more depth how to make that battery. Now, what do we do next? First, let's get the plywood. plate that we are going to put on the wall we are going to use this to make the box to put the batteries and I have the Society chosen to make it 21 and a half inches -eye, 29 inches long, this size is more or less Chosen at random only because my batteries are a little bit bigger, so I'm giving myself a little bit of wiggle room to be able to install the wiring and all this other stuff, so let's get started right now.

Once this was done, we made the box. we just put these sides here and I painted it black so it looks nice there will be like this on the wall the battery will be here these are the sides yeah you want to see just black holes that's right let's put the battery there and Now that We put the batteries here, I've decided to split them on the sides here and then use a single piece here to hold them. This space here could be used for connection. Maybe some electronics here will figure out how we can hold the batteries.

I decided that two of these little things are enough to bend those plates there, but before we hang this on the wall, let's talk about how much energy is stored in these cells. There are 300 cells here. There are 300 more cells here, so there is a total of 600 each cell is at least 2000 milliamps if you multiply 2000 milliamps by 3.7 volts, which is a nominal voltage of these cells that equals 7.4 watt hours per cell. If you multiply that time by 600 of these cells, you get 4,440 watt hours, so 4.4 kilowatts of power in this group of cells here, and so how do you connect that?

You can wire them in many different ways, you can group these cells however you want, but the most logical ways to do it of course depend on the inverter you are going to use, so basically it is DC power, you have to convert it to AC to To be able to use it in appliances, what comes out of your plugs is AC, so you need an inverter. Is there a device that converts the BC to AC and are they usually set to run on 12 volts, the smaller ones and then the larger ones started running on 24 volts, 36 or 48?

I think the bigger the bigger you can run an entire house it's usually running on 48 volts and so depending on what device you're going to use, what inverter you're going to choose to use with this cell, that's going to determine how you're going to connect these cells. How do you do that well? If you want to wire that for 12 volts, that means you'll have to have three groups of cells. You will have to divide the 600 into three and that is the amount you will have. connect the wires in parallel, so if you're going to want to use them with 24 volts, that means you're going to have to take the 600 cells dividing them by six, which is a hundred, and then those will be your groups, groups of a hundred cells and you're going to connect them in parallel, the six groups, then you will have to wire them in series so that you can get 24 volts and so on 36 you will have to know the groups are going to be smaller for the groups they are even going to get smaller, so now that we have said all that, we're going to install this on the wall, we're going to use our level here, it's there, okay, let's I'm going to hook up some of these guys so we can disconnect, connect and disconnect through contactors, okay guys, so here it is, this is the power wall, these are the interiors, here there are cells, there is a cable that comes from both, then I put it. connected to another wire that goes and then connects to the contactors and then from the contactors it comes out and then those wires here that's what will go to the urine, whatever we decide to use as an inverter and then from there it goes into any of both. this thing here to charge a vehicle or it goes into the wiring of your house or your building so you can power your house directly to the inverter, that's what you would connect the

solar

panels to if that's what you would do and so from the solar panel it would go to the inverter and then the inverter would charge these batteries.

There are some inverters that have a built-in function so that they can keep the batteries in a certain state of charge, so the only thing we're left with is what I'm doing here is covering that and also that all of those things are exposed. I have something special for that. Look at this, yes, this is a piece of glass and you can put whatever you want here and I decided to do tests, so let's see what it looks like. like there, okay, so there it is, this is our power wall, our DIY power wall, right, 4.4 kilowatts, how much did it cost us to make this?

Well let's see when I was buying all the dead laptop batteries, I did the math and it came out to about 30 cents per cell, there are 600 cells in this box so it comes out to about $180. I don't know, it's $20 for the wood we use here to make the box. Add a hundred dollars for this glass here. I did it and you could put any photo you want here. I'll connect to this service, that kit that will make this glass and you can put whatever. You can put a photo of your face. You can put your family.

Your brand. Whatever you want. In this case, I chose to do the test that looks like a Tesla Powerwall. You're looking at about $300, four point four kilowatts, and a cost of three hundred dollars. If you know that for about a thousand dollars you could make another three of these and that gives you about 13 and a half kilowatts, that's a better deal than Tesla's offer, so for $3,500 you could have about 20 kilowatts, 30 kilowatts, now You know, if you do it right, you will save a lot. I know it's a lot of work to do all of this, but once you get the hang of it, you'll be an expert.

You'll be checking them out and up on the wall in no time. Next time we'll show you how to do it. to choose the best inverter for your application, which ones are best for solar, which ones are best for charging your car, which ones you know best just for powering your home using the grid, okay so stay tuned to that video, thanks for watching. Next time we'll have the same loud rocking, no, I don't like that.
