Question: I am definitely interested in building a power station rig like this but using PV Solar as power input to thebunit. For this house, I am not trying to invest in full home solar thus I thought about building a station like yours without knowing if it had been done before and came across your plug and play build so thank you so much for taking a step-by-step approach in order to show all of us. Finally, to my question, if you're building just for EV purposes, as I am aspiring to, couldn't you just boost dc output to charge the battery directly in order to reduce power loss as much as possible? If it helps, we have a Rivian R1S with the CCS plug but we have a NACS adapter and I am hoping to take delivery of an Aptera next year which was the first non-Tesla vehicle to have permission to use NACS and will undoubtedly use it so NACS would be my output connector for simplicity but wouldn't be opposed to CCS since existing parts may be going down in price due to obsoletism. Isn't it more efficient, in most cases, to output DC in the end? I am highly interested in this and I'm surely not alone. Please advise on your thoughts.
Great video. Provides a lot of options. I think the industry in general is still overpriced (Nothing to do with you). $8500 & $4500 is still too expensive. In a few years we'll probably be getting SS batteries and these prices will need to be significantly lower especially if general population acceptance of battery power for the home/car is to occur.
I agree, lithium products will see large deceases in prices in the next few years. CATL is releasing a sodium battery in July 2023. Lithium might still have it's place for now. Jehu better sell as many as he can before getting stuck with them all 😂😅
@@jehugarcia No disagreement with you. Prices are at their lowest. I just think for powering homes and charging cars the technology still has to improve and the prices still have to come down for mass acceptance and market penetration.
I wonder to build a DC-DC charging rig rather than solar-dc-ac-dc car battery with extra costs and unefficient. Which DC voltage can support bateries packs in series?
It all depends on what you want and how much work you want to put in. I'll just go with the rack mount batteries. I'm not stuffing around with the small stuff. I do that with the power tool batteries i repair and build
On the DIY battery rack (EB4)...how would you charge the RACK up? (I already have 3 on a small system....But I want a RACK!!!...haha) Solar / Sure power?...Charging Options
Nice video, Jehu. The DIY looks like Frankenstein, though. LOL. If you place nice covers on each of them, you can start a new business. Those will sell. Not only for people without a place to charge overnight, but for emergencies.
This is a diy build. It is not safe for retail sale. The batteries are not mounted in a way that running into it with a car wouldn’t move the batteries around. There are plenty of consumers that are idiots. That’s why diy is so much cheaper. I learned a long time ago not to lend one of my diy contraptions out. 😄💥🧨
Jehu I love your videos and find them informative and inspirational. I'm looking to use this setup for a whole house backup. it hits the sweet spont between simple and affordable. I see 4 DC power strips with one Anderson connector each. How are you combining the 4 Anderson connectors together to connect to the inverter? I'm very interested in this project and this is the only part I'm missing. What inverter would you use for a whole house backup? Grid tie with solar would be ideal.
How were the power strips mounted onto the cart? It kind of concerns me because it looks very flush with the metal cart that it may cause a short or fire.
This is definitely a diy setup. There are open connections that can short if a conductor touches the wrong points. Personally I would buy some liquid wire insulation and paint every open connection.
These E-bike batteries are lithium ion aka lithium cobalt oxide LiCoO2. They have greater energy density but are MUCH more dangerous than the Jakipier Lithium Iron Phosphate LiFePO4 batteries. People have died from their e-bikes catching fire in their homes or garages while charging the bike at night. LiFePO4 batteries will mostly swell and boil, but not combust, if overcharged or damaged. I've accidentally caught 18650 cells on fire through a dead short through lose termination. I was lucky it was only a 12 volt pack. I would encourage everyone watching this channel to stay away from 18650 Lithium Ion cells for DIY projects. You are much better off with Lithium Iron Phosphate.
Nice build but I would recommend losing that cheap, short lived, low surge capacity, high frequency, transformerless inverter and stick with the low frequency, transformer based inverter that you used in your previous rack mount build. High frequency, transformerless inverters provide a much lower surge capacity and a shorter life expectancy than heavy duty, low frequency, transformer-based inverters. Additionally. high frequency, transformerless inverters do not provide any galvanic isolation between its DC boost stage circuitry and its AC output which can allow high amperage DC current to pass through to your AC loads and damage them.
so hook up a little trailer so you can tow it behind your van for backup on a long trip, there won't be much loss in overall combined battery life between the 2( the pack in the van and the 1 being towed). adapting a solar panel for the towed battery would work for charging assistance
For conversation purposes, could you just put these battery systems on a towable trailer and just tow a range-extending battery? Can you plug some form of a charger into the charge port and drive at the same time? I assume someone like you could figure out how to hard wire it in but I'm thinking about this from the perspective of an aftermarket plug-and-play product.
@@whattheschmidtthere are portable dc fast chargers for sale... but they are very expensive. I wonder if there is a diy solution for a DC/DC converter...driven by signals from the car...🤞
Have you every decided to make a big battery for a motorcycle? I would love to see that and I'm sure many people would like that see that build as well.
@@jehugarcia There is one company called SparkCharge that makes a portable battery powered DCFC but they’ll only sell it to businesses. I was hoping you could come up with a DIY version of that.
I don’t get why you would charge a batter to charge another battery there are losses each time you do this in the form of heat, each charge typically looses 10-15% therefore charging and recharging costs you 30% more I know power in California is cheap cuz you get it for free from British Columbia Canada we pay 7 cents a Kw and I wouldn’t double charge 😢
It's a dumb idea to charge an electric car when you have electric power... would be good if they were charged by solar to then charge the electric car...
Dude... put the charger at 240v and put the inverter at 240v to compare apples to apples. Your cost comparison is not equal. It will take you 10 hours to dump the load in the Rivian to get like 40-50 miles... makes no sence
Man …this man misses the mark do it your self making it easy for soccer moms to be Able to do it …yes he can do all that of course get a 240v inverter blah blah blah …but he’s just demoing the batteries showing the minimum possibilities for cheaper
You are comparing the price of two different setups. Yes , there are no 6kw 36v inverter on the market... and that's my point. sO you should not compare them. Having an EV and waiting 10 hours for 60 miles of charge is not practical ... sorry.
@@jehugarcia Respectfully, I learned enough to know and see that you are now using this channel just to resell batteries for profit. And that's OK... all the power to you. Some (not all) of your builds you demo here just don't make sense. Your A123 stuff is good for example... this is simply not.

21kwh of battery has never been cheaper than now.

Damn I wish you were my neighbor. So knowledgeable on this stuff.
I add a power inverter to my 2013 Nissan leaf. It’s 20kwh of battery. And it’s also a car to grab groceries in. :)

Nice. And it looks professional(enough)! Good job Jehu👍

How many cycles do you get from the DIY version? Because the LFP plug and play uses different chemistry which typically lasts longer
Estimate is about 2000 cycles on that duty cycle.

Fusing/breakers between packs?

I have a question can you use this kind of battery setup as a emergency generator for a normal house hold???
Yes
@@jehugarcia but do you than also need a inverter ???
Yes batteries are dc voltage, residential uses AC so you need an inverter

yes ive done it before
And then mount solar panels on top of the trailer to charge the batteries!
Jehu, what about a diy version with DC charging and CCS?
It should give you a much higher output power...
Would it be feasable?🤞
I don’t know how
@@jehugarcia
Could be an interesting challenge for you?🤞
That's what I was thinking the whole time...the conversion to A/C then going to the charger on the car to go from A/C back to DC power....ugh
@@whattheschmidtthere are portable dc fast chargers for sale... but they are very expensive.

I don’t motorcycle
Can you do a 40-50kW DCFC version?
I don’t know how, I think there’s is a 50kw dc charger but it requires 3 phase AC power not batteries and it’s $20k

how to get in contact with you?
You just did
DIY always seems to be less expensive and yo can get any amount of power you want not like the plug and play
I've got one of these - its called an extension lead 😆
Great info thanks 12:35
How do you charge either of the battery packs between uses?
You plug them into the wall
@@jehugarcia Ah, I didn't see where they had a built in AC charger. thanks.
not gonna lie looking at them combiner board screwed to the metal cart I was a lil worried
Nylon is a great insulator
Let's goooo
I’ll stay

Only thing is that DIY batteries are not readily available.. smh
It's a dumb idea to charge an electric car when you have electric power... would be good if they were charged by solar to then charge the electric car...
