Ben is a great guy, just like you are, David and I can't thank you enough for all of the help you have given me in the past. Introducing me to Ben was another big help and with Ben's assistance, I was able to complete my solar system by copying his battery bank system with my LTO batteries.
I love to see an explanation of or guesstamizing of electrical components by touching them without gloves, or ground strap, or a 2x4 and a buddy at the ready to smash you off, when you start convulsing and smoking from magical watts!!...Very cool video, loved it!!
I’m glad to see someone using these batteries in a different way. You both are much smarter than me so I’d have to pay someone to set it up for me and that would probably run the cost way up. Good job guys..
Glad you enjoyed the tear down. This pack was designed for Volvo by LG Chem out of the Detroit area. Careful with those coolant leaks, they can create a loss of isolation or potentially a short circuit if it ends up in the wrong place.
Great video (as usual). I love seeing how these kinds of things are built! Your comments about modem packs and spot-welding were funny. Keep in mind, there was no Battery Hookup (or general availability of these kinds of batteries) when some of us began this hobby. :)
EV batteries are great. The cells are so well matched. Practically stay balanced on their own. I’ve got a bunch of 60v Chevy volt packs. Love them. The Volvo’s look very similar. I put mine outside recently to mitigate the burning down the house risk.
I've been running the Smart ForTwo and other batch of volvo batteries for almost a year now, and everything is still perfectly balanced!! They're definitely awesome.
Nice and compact modules. A little pricey when you compare them to LifePO4 cells but the additional scrap hardware is nice to have- contactor & flex cable. Note the discharge curve is not flat for Li-NMC as it is for LifePO4, stopping at 3.9375 / 63v would leave roughly 20% capacity. Maybe Sol-Ark will have a firmware update that ups the top line voltage in the future.
If you can charge the car with a standard power plug, then all you need to fully charge it is the build in charger. Unless that tech is build into a larger computer system. Perhaps get the at home charger from Volvo and power that thru the Sol-Ark. if the house is set up as two parallel systems, you should be able to do this
Then you would also need the built-in charger, as it's part of the car and not its battery. Plus then you would need to use the battery in its original 6*16=96S configuration, which is about 350 volts. It will be hard to find a way to use a 350 volt DC source, 48 volt equipment is much more common.
Also as you find in electrical courses that electrons flow on the surface of a wire. So more strands(or in this case,,, flat plates) then the higher the current flow for the amount of voltage. There is a trade-off though so not all perfect LOL Heat is a problem for the smaller wires or plates as the resistance is still the same no matter the size of the medium. All in all, one of those battery packs at 56v would be perfect for my electric tricycle. Too bad they aren't sold already removed from the vehicle container pack.
No. That is a misinterpretation of the skin effect, which is a tendency for changing magnetic field induced by an alternating current to push electrons to the outside of a wire.
I dont know why but in the thumbnail, I just thought it was you with a beard. I didn't realise it was some other guy completely till I had a better look. 🤣 🤣 I love seeing what all is hidden in industry made systems so very cool.
With all those water connection failure points, I can see why it may have leaked. The cooling is not elegantly simple. I like the Bolt battery cooling system much better.
Save the contact relay they probably have arc suppression inside they might even be solid state switching :) Toshiba maybe Siemens or a vacuum mechanical relay nice for batteries in a basement have fun 👍 🤔
Was this dude poking at a high voltage pack power out w/his bare fingers w/o knowing what a battery disconnect is and if it was installed? I hope he at least threw a multimeter on it prior.
Probably could, but there's no need for cooling with what I'm using them for. I never see more than a 1-2 degree rise in temp even under heavy charging.
How good is the deal since he can't use some of the capacity in his setup? I'm not sure you considered that into your calculation. Nice though that he saves from having to build from scratch.
heya oh yeah 1 more trear down of a big battery I love to see it. I would love to do it also my self but still don't know how to get me 1 greatings from the other side of the pound
Nice video . These EV batteries are getting more available and affordable. The only highend inverter I know that would work with 16s voltage is the Studer. 38-68 VDC .
So guys I need a recommendation on inverters..I have 2 2017 and and 18 kia optima hybrid battery 360v 68kw and 9.8kwh . Oh by the way it lithium ion polymer battery
Let me correct you on the layers of copper plate in bus bar that is for current flow not for vibration. If you increase surface area of a conductor current also increase because of electron increase on surface of conductor more the free ectron more the current flow.
One question i am always left with after seeing these EV battery teardowns, will the coolant need to run in order for the battery to run safely? and if not why is that?
Not in Bens setup. In a car the batteries might have to move 300+ amps for a short time. Think accelerating onto a highway, up a hill. The cells would get hot doing that and need active cooling. In Bens home setup, the maximum possible amps these cells might see is 12 amps. they won't be getting hot at 12 amps.
I'm a owner of xc90 t8 (2021 early model). I'm just wondering if 11.6kwh battery can be replaced 18.8kwh battery physically. As I heard, new xc90 recharge t8 (MY2022) has 18.8kwh battery inside. I want to upgrade if possible.
Did you sell the battery case? I broke one of the plastic coolant pieces. trying to find it online so i can sell the complete un damaged case. What car is the battery even from? Battery hookup doesn’t say.
No need. The amps moving in/out are very small in a home setting. In Bens setup it maxes out at 12 amps per battery. The batteries are made to handle 300 amps. They just don't get warm at 12 amps.
Do you think a cars alternator would charge a u charge valence battery from battery hookup?It doesn't have to be a full charge but enough to run an inverter for some camp lights/shower pump?Or would it be better to use a pwm controller and a 80watt panel?Those are my options and the stuff I have other than the battery.Im trying to go as small as possible on my camp stuff but need an additional light weight cheap alternative for my power needs other than lead acid I carry on my truck rig.we are going to be using a small car for kayaking trips rather than my big truck we use for hunting trips.Any ideas/thoughts are greatly appreciated.thanks
Hi Chris Lewis, The short answer is "yes" a cars alternator can charge an extra battery. However, there are some pit-falls to avoid. The worst situation is to burn out your alternator. The best practice is to use a DC to DC charge controller. This is a device that monitors and slowly charges your accessory battery (like the Valance or whatever you choose) Here is an example of a good one: amzn.to/2SAZzkD
Battery Hookup currently has some 8s (8 cells in series) modules. Here is one at a great price: batteryhookup.com/products/l-lg-28-8v-7-9kwh-8s-lithium-ion-ev-module Please use discount code DAVIDPOZ with your order
Wow $132/kWh... Now I'm torn I was about to look at some SBS 190F industrial pure lead AGM batteries for $100 per 1.1kWh roughly (190AH) Any advice from anyone why one battery technology would be better for solar energy storage?
Nothing wrong with AGM. In my opinon, AGM makes a lot of sense if you are looking for a backup system, that sits full 99% of the time, and only is used a few days a year during a power outage. If you are looking for daily use in an off grid solar system, then Lithium makes more sense. There are several types of lithium batteries. I'm currently using LiFePO4 chemistry in a pre-buiilt 48V option. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-SYJ25izYSGc.html
hey David at 12:02 you said each module is 2KWH and total power is 16KWH of the car battery but I only see 6} 16s batteries so if each is 2kw times 6=12 kw did I missed something ? and David can you please provide the link for that Volvo car battery thanks in advance for your help !
You got me, that was a mistake on my part. Each is 2kwh, and there are 6 modules. Making 12kwh in the car. Lots of 2s and 6s jumbled together. Sorry. The battery is currently out of stock at Battery Hookup. Sometimes they sell out super fast. In this case, faster than I could film, edit, and publish. batteryhookup.com/
@@DavidPozEnergy thanks David for your reply. so it is 12 kw total for a moment I thought that I missed something ! and they are out stock too bad, so that is why I could not not find any of of those modules at battery hookup. they were all sold out in the time I was watching your video, it was like with the BMW batteries in one of your previous videos. but I kept in the look out for them until I managed to find them in stock, and bought 3 crates last year. anyway thanks for your update I will keep my eyes on battery hookup hopefully they are back in stock!
Would this set up work for a skoolie solar battery bank? I’m totally new to all this but really want to keep used lithium out of landfill. And it seems to give way more hours than a commercial battery. Volvo vs Nissan Leaf? Is one better? Is one easier for the beginner?
Yes, it can work with any off grid solar system. These modules are about 58v nominal, but work with a lot of "48v" equipment. Ben is using it with a 48v sol-ark inverter. It would work even better with a Victron inverter since most of those will go up to 66 volts. Just make sure you add a BMS. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-i22xYD3DuWY.html
Is there any way you could do a video on a lithium conversion with battery’s from this same place for a Polaris ranger EV? The company’s that do a conversion charge $6-8k for their conversions. There has to be another way 🤦🏻♂️
Are you in Massachusetts? I've done a lead to lithium swap in my golf cart. It would be the same sort of thing for your Polaris. You just have to check your voltage range, maximum amps, charger, and a couple other minor things.
Does it need to basically run threw some type of bms before it goes to the charger if comes with? It’s a 48v system. I’m in NY, but I would trailer it to you, just to get your advice and look at it!
David, wbatd going on with your speaking style? You're speaking in this overly precise manner like Mister Rodgers. No big deal, its just kind of weird.
Am I? I don't always film a narration after the filming. So maybe it's just because I've had a couple days to collect my thoughts? Usually I'm explaining as I'm also building.
Why in the world were neither of you wearing PPE? one mistake with open circuitry on high voltage batteries, and it will be the last mistake you ever make. 💀
Its not so bad. Gloves would be best but if you have your multimeter and test for voltage before touching things you’ll be fine. Find the positive and negative terminals and don’t short them.
You guys are setting a bad example here. You were not wearing insulating gloves and were using metal tools to work on the battery. Need to do better here. Also, the so-called “Orange Cap” is a safety device used to disconnect the battery. I enjoy watching your DIY programs, but you need to do better.
