Hacking a Scrapped £90,000 EV Battery to get FREE Electricity - DIY Vehicle to Grid - Part 2
Вставка
- Опубліковано 21 вер 2024
- There's a crisis on the horizon, when all of the EV batteries being manufactured, reach the end of their usable date as an EV Battery, they're expensive, energy intensive, and complicated to recycle. But imagine if there was another way? Imagine if we could crack the code on these batteries, and connect up EV Batteries to the grid, or to power a house with stored renewable energy? Well, let's give it a go, how hard CAN it be?! Grab some popcorn, and sit tight. We're going to the future! 🤖
( P.S - You can often get electricity at night time, and off peak for FREE, and at other times even get paid for it. You can then store it, and use it during peak hours. Check out octopus energy 🐙 - Sign up and we both get £50 credit! - share.octopus....

It seems the 95% statistic could be wrong! It seems I might have been mis-informed, I’ve posted the link to where I sourced that stat from. I apologise unreservedly if this is wrong!
The point still stands, reuse still beats recycle… even at 40% capacity, these batteries are perfect to re use in lower capacity installations. And in this case, we got the battery for free, and it’s working perfectly!
Just about to come and tell you your stats are wrong 😂but, you are correct reuse is better than recycle and what happens to the majority of ev batteries are used home or converting ice to ev. Great video
Well done for showing your mistake. It is still a bad picture re lithium batteries and the world needs to do better. Fortunately that is hopefully changing. As for car batteries, the Dutch now have a football stadium run by repurposed EV battery packs. I would love to see an in depth video of that setup as it looks amazing.
You're probably right, just the EV cult members are very touchy
@@Distinctly.Average Let's hope they have a lot of fire escapes.
At one point, it was as poor as this, I suspect its just bad or dated information you have sourced.
I hope there's a part 3 Cory! These are my favorite kind of videos
Two Wallies Blow up New Forest 😂😂
🤣
And it would be blamed on climate change.
As a 50 something IT guy I get overwhelmed most days. Just take a breath, walk a lap of your desk/van/block and it'll be much better. You're never the only one
Was our explanation in the video clear enough? If not, let us know and we can explain in more depth here in the comments! As always, thanks for watching! 🤩🤩
Would be nice to know the full setup including the lillgo's in the final working setup and to see it all nicely packaged away in enclosures :)
i did all my sparkly training in the very late 80's so it's amazing how far things have come, yet stayed the same
what i'd like to know is how the car battery stuff differs from the home battery stuff in terms of all that canbus business for starters because i'd assume that all the internal gubbins in the battery electronic wise would still be the same across all platforms
ultimately you guys have just fooled the battery into thinking it's still in the car if we simplify it right down to basics yes?
thanks
As an American, for about 10 seconds, I was wondering why you said the car was 90,000 pounds (45 tons). Not an actual complaint, I hope you find it amusing :)
Can you make the actual setup, components, pin outs, software settings etc needed to replicate what you have done available to others..... here at Blue Zero Project we would certainly purchase that 'kit' if you had it for sale
Two of these would be a pretty good storage solution for us
Who is 'Lily'? And why is she pretending to be a landrover? 🤨
To add, I was a mature graduate and have worked in power generation as a controls engineer but i graduated as a chemical
And process engineer and I have felt like an imposter my entire professional career, but the more I do the easier it all becomes, I just worked in a cruise ship starting a gas turbine that has been dead for 5 years, I ate with the guests and slept in the bowels of the ship with
the staff, I got the old controls working and started the GT first time, I always feel
Overwhelmed but life can be good
Absolutely awesome lads. That's quite an achievement. Anyone in electronics knows that it required the multi skills of both of you to make that home storage idea possible. Well done 👍
Thanks! 🤩
Lmao that driving instructor calling himself a mobile mechanical engineer 😂
😂
Ha ha, that Sun headline really made me laugh. Especially the spelling of ‘exclusive’, which I hope was deliberate! 😂
Glad someone got it!!!! 😆😆
I'm a senior IT geek, imposter syndrome all the time, but also there are very smart people out there, so please don't go in the opposite direction and think your better than everyone.
Most people who are calling themselves 'engineer' are usually doing work that would be defined as a 'technician'.
If you're assembling, then you're a technician, if you're maintaining, then you're a technician.
If you're doing complex calculations to design a system, not just following rules of thumb, procedures or simple formulas, then you might be doing engineering.
A simple voltage drop calculation wouldn't require much engineering knowledge, that's just a procedure.
In the UK, the term engineer is abused, in other countries the title Engineer can only be used if you've qualified and been certified as an engineer by an approved professional body.
You thought about it carefully, then you hit the nail on the head
I blame British Gas - every plumber now thinks they’re an engineer 🤦♂️
Just to add, The professional titles of Engineering Technician (EngTech), Incorporated Engineer (IEng), Chartered Engineer (CEng) and ICT Technician (ICTTech) are the only protected titles. Need to be paid up engineering council member to use that, or they can sue for committing fraud.
My first job title was 'Thermo-hydraulic Ceramics Engineer', it was too hard to pronounce for most, so I didn't mind people referring to me as 'The Dishwasher'.
@@1992Craigster I spent 10 years achieving my CEng, not to mention the yearly EC fees on top of hefty IET membership to retain it (work pays it fortunately) - sadly because the engineer part is used for any old Tom, Dick and Harry title, no-one is any the wiser as to what it means 🙄
EV manufacturers should be required to release full technical information about how to repurpose their batteries for other uses, rather than letting them go to landfill prematurely. They should also be modularised so they are repairable.
I agree!!!
@@shaunhw I believe BMW batteries can be broken down to 48V batteries quite easily.
You have to be prepared to strip them down, so you take some risks doing that and you lose the advantage of the casing of the battery.
As you say, it would be nice if EV vendors were required to publish specs, not just for second use but also for third party battery upgrades for vehicles.
Well done to everyone involved
I expect this kind of thing will become more popular, i remember seeing a few years back nissan leaf batteries being used for the same thing and having code released so others could do it. I wish i had the knowledge to get it done and safely
It would be awesome if they worked on a universal reusable comms basis!
Excellent I’d been looking forward to seeing this update. I’d say there is a huge business opportunity here, building “kits” that connect car batteries to inverters 👍🍻
Great to see you back Cory, been looking forward to this update. Cheers :)
Hey, thanks! Good to see you back again
Cory, that was very enjoyable and, as already mentioned, you needed to either extend the "hoorah, it works" footage and show us more of the finished project or upload a "Part trois" please, with the aesthetics of it all with the home electrics done and dusted. I think there will be a few entrepreneurs wanting to bring this to market for end of life cells.... a Dragon's Den item if ever I saw one!
I swear, when the LilyGO "exploded", I could smell burning!
🤣🤣🤦♂️
@@TheJimODonovan electronics is powered by magic smoke, when the magic smoke gets out it stops working.
Feels like you opened a massive door into the world of repurposing. Well done both of you for sticking at it, that was epic. So methodical, lol
Thanks mate! 😊
This isn't new at all, people have been repurposing EV packs for many years without all the sodding about. Break the pack down to the core cell packs and use an off the shelf HV BMS solution like open BMS or similar. Great video non the less but a total waste of time when pre-made kit is already available to do the same thing.
@@bas5946 i kinda knew that as i wrote but went for it anyways.
Well done, well done indeed. That canbus hack is nothing for a weak soul.
The biggest concern is ensuring the BMS is keeping the cells balanced and providing over and under voltage and current protection.
So, we’re re using the internal BMS, we’re just reading it though, and then setting our own thresholds and controls of output. For example we’ve set 80% as 100%
@corymac I hear you. Just make sure it is doing its job once it's up and working. Cell imbalance can be a very ugly thing!
Yeah that is one thing we need to check still. But so far it seems that the iPace BMS keeps the cells balanced at all times.
"Surround yourself with people who are better than you"... Cut to me... You must be joking 😂😂
Having spent the last two years working on the onboard H2 pruduction & compression unit for the Blue Zero Project yacht being overwhelmed is now my normal state 😅😅😅, that said I now have a working prototype that can indeed produce H2 and compress it for storage at 300 bar all onboard a sailing yacht and from solar power.
Next up is the battery storage solution and why I'm here following this awesome work....
There is always a solution to the problem, it just needs to be found
That’s incredible. I’d love to come film that! So you’ve built a solar electrolyser, and an on board fuel cell I presume? ( info@oyelectrical.com )
Sounds impressive but why waste electricity electrolysing H2 and compressing it then losing more energy putting the H2 into a fuel cell or ICE when the electrons can straight into a battery?
One thing that is worth knowing refurbished lithium cells are all over the Internet. It may be possible to simply break the battery down into individual cells as the likely is a few have gone bad whilst the rest are great. For my personal use I have actually manufactured some circuit boards that do this and once you know how to trick back into work it is the easiest thing ever. Currently training
Part 3? Showing the whole system working, and a summary of everything......that would be awesome
Ok mate, will do
Im a high school graduate and licensed electrician. Over the past 43 years, I've developed an electrical, mechanical, and civil design/ build company, creating a wide range of products for the electric utility industry. My major customers are some of the largest utilities in the US. Just break it down and figure it out!
For several times in my current job, I felt like I needed 3 of me to all the work that was just dumped on me. I stepped away for a for a minute, broke everything down in to simple jobs & it got done far quicker than I feared. Things in life always seem more scary when they all come at you at once.
I agree, sometimes just head down and crack on, is the best way!
When B.S scrips are written by a.i chatbots 😂😂😂😂😂😂
Fantastic work Cory. You just created 8 powerwalls. Please don't leave us hanging for a month until the next video 🎉
Thanks Alan! Another coming soon
Well done very impressive
The art and the impulse to mentour others is alive and well! I think people forget how important it is to teach, not just stuff, but how get the best out of yourself and life. Good job guys... and yes as a DIY obsessed IT consultant I feel overwhelmed at some point most days but as I keep telling my kids "Your comfort zone should be just outside your comfort zone" Keep up the good work
We were taught by someone kind enough to teach us, it’s only fair we treat others likewise 😁
Im an IT Tech and been tinkering with PC's etc for over 20 years and even I get overwhelmed. Im off work at the moment because if it too.
Hi. I'm a 2nd year apprentice, and would love a unlite package. Loved all your videos since the artisan days, keep up the good work!
DM me on insta, James!
Now add a second battery, Dala's updated the firmward or hardware for that I think.
An excellent documentary of your (successful) efforts, showing all the missteps and tiny steps forward towards the final goal. This is what engineering is like 👍👍👍
Glad you enjoyed it!
Amazing job! Very pleasant ro watch with the good explanations. Well done.
Nice
But I really hope that one day, there is a common battery communication standard so you can plug a vehicle battery on an inverter, and it just works (in a safe manner).
Battery Emulator is close to that. It's probably as close as we'll get.
there's so many standards! but also encryption...
you have got that so wrong with regards to the car batteries being recycled most of them are repurposed like what you are doing in the video. there are more disposal vapes in landfills than anything else.enough to make 30k battery packs
These are public statistics I’ve got, not my own.
Also, vape video coming soon! We just need to collect 4788 more before we can film 🤣👍🏼
Actually, most places will not release a battery to you and say it has to go through disposal channels that they need to use due to the manufacturers service agreement
@@corymac For full disclosure and transparency please post a link to the “public document” you reference.
Bore off lads, it's just a UA-cam video - a good / fun one at that.
@TroggyPB Why require when you can just google it. One article from BBC "Electric cars: What will happen to all the dead batteries?" The 5% are quoted from Paul Anderson from University of Birmingham 2020/21.
I used to be an underwater ceramics engineer for a while -
I think it’s more commonly known as a kitchen porter/ pot washer
😂
Been waiting ages for this update!
Congratulations and well done to you all! It goes to show that tenacity pays off in the end. It would have been so easy to give up after the first hurdle.
Thanks Bryan! 🙏🏼👨🔬
We don't give up after small setbacks. We work until it's done.
The apprentice that left a voicemail couldn't have got it so wrong.
Exactly, but I remember feeling the same! 'wow, everyone else, especially these adults, really have it all figured out!'
Well done in getting it working
Bloody good going guys, well done on that one. I have been a fan of the second life storage community for a couple years and there use to be a crazy ozzy doing some serious 18650 massive pack building with recycled cell's so i know it can be done. It would be cool to see a finished product with a walk through of how ya actually ended up doing it.
Hi ... can you make the detailed process available for other's to follow...? Putting together detailed how-to, with pin outs, software, and components would be a very real benefit to others and help fund your channel.
I can definitely look into this, although it would be very time consuming. Perhaps let’s chat about this over on the members discord?
Is there coding stored anywhere online to have a look at or a write up of everything? Stuff like this need be made available for everyone in future
There’s not, it’s all proprietary and understandably, hidden
@@corymac what about your coding technically could release as open source 😜
This was just so awesome. Respect for making this.
Thanks dude!
@corymac cory may i say a massive thank you for allowing us all to be a part of your battery 🔋 journey. I cant believe there are people pulling what you all have done regarding this endeavour, totally jealous people in my opinion! Those the can do those that cant, well do i need to spell it out?🤔🤣. Also thanks for introducing Chris! An absolute warrior! Well done on what you guys Have managed to get done and keep up the awesome work. 💫🌟💥👍
Thank you. I'm a bit camera shy and awkward 😂
The recycling statistic at the beginning is a bit misleading. There were 2 data points mentioned - first was that Tesla produce over 7 billion battery cells per year. The second piece of data is that the recycling rate is 5%. However, these 2 pieces of data are not related to each other, at least not right now. The implication is that 95% of the 7 billion batteries being currently produced are being dumped into a landfill every year. But the truth is that no one is dumping 2023 Teslas into landfills just yet! Maybe in the next 10 years, those 7 billion cells will need a home, but in 10 years its very likely that recycling cells will have vastly improved. So yeah, it may be true that 95% of cells end up in a landfill. But these are electric cars that were manufactured a long time ago, when there were a LOT less electric cars being produced. I doubt its even 1 billion cells being dumped in landfills right now - just go to a scrap yard and see how few electric cars are being scapped.
I apologise if it was misleading, that isn’t my intention. However, I got this battery from a scrap yard, where they’re absolutely not sure what to do with the volume of batteries they’re receiving ( hence how I got this one almost free! ), if a car has even a slight bump, the insurance companies write off the battery to ‘play it safe’, meaning the battery isn’t allowed to be used for anything, even when as you can see in this video, it had 99% state of health, and NO signs of damage.
They can’t be stored without an insurance implication either, and there’s no infrastructure to handle the levels of recycling needed. It’s a scrap yard nightmare. We’re preparing at the moment to potentially take all of them from them, and make an industrial scale system. Subscribe and it’ll come eventually! 😃👍🏼
@@corymac already subscribed! And sorry to nitpick a tiny thing.. this video series is excellent 👍
@@corymac what a fantastic plan, I hope it comes off
There's a reason there aren't many in scrap yards, they are an insurance nightmare and most Scrapyards have specific clauses banning them for having EV batteries on site.
@@corymac must have been a very ignorant scrap yard. Most of them copped onto EV batteries' value many years ago and they now sell their packs for top dollar. Only too many fools around like you and me buying them 😂
Brilliant work well done 👍🏾
Been waiting for part 2 for so long!!!
Worth a part 3?
Absolutely love this content, inspirational 👏
Glad you enjoy it! Thanks for the comment 🤩
Great result - and importantly open source for others to benefit 🎉👍
I think this is a very great step - please work with other batteries to use this solution with a lot of HV-Inverters. If you how the CAN-Bus commands the rest is easy to connect.
It’s a good engineering work. Think of a modified Wallbox with WLAN-CAN Bus commands to the battery. 12V and a cheap WLAN-Modul should do the discharge for you. You can use the wallbox in two directions. The battery rest in the car and the house inverter become current over the Wallbox.
We’re on it 🤩👍🏼
15:04 As that drum beat kicks in, for a second my mind went to Black & Orange UA-cam. 😂
Thanks for giving sources, I suspect the reason is that currently very few packs are totalled as worthless and sent for disposal?
Nice one. I guess the simple approach to bypass all the jag logic and just close the contractors is best. Will it still be able to balance the modules in the battery though?
I released this by accident!!! 😂 - I wanted to do members only later this week. But hey ho!!
Yes, so basically, the full BMS is being read and utilised, but the contactors are seen as satisfied on the circuit board with the resistors we’ve added, and then we control them according to a few different stages of charge that we’ve set
The BMS in the battery seems to balance the cells automatically!
Wow! Brilliant, well done.
Glad you liked it!
Excellent, well done.
Many thanks!
well done, loved the project, I hope there is a part 3? and longer :)
Thank you! 🙏🏼
Great series! Love watching the videos. Idk if the 6 unilite apprentice care packages have been taken but I’d love one!
Nice one guys
Wonderful project guys :-)
2 Years into electrical apprenticeship, question I have is what is the best method for an efficient and speedy install, is pre-planning the best way to combat this?
Good question! Let’s let the community answer this for you Deano 😃
I've always said the hardest part about being a spark is finding the best route to get the cable to where they need to be especially working on exiting buildings, so pre planning as much as you can but be ready to expect any changes needed. I'm qualified 10 years and every job big or small it's always what route am I taking.
To sound unhelpful, it's foresight due to experience or working with someone who has learnt that foresight. The more logical and puzzle solving your brain is, the more successful you'll be.
Having a well organised tool kit and van, jobs rarely go as planned.
I personally for planning a job, I prefer a notepad and just draw out the job, as I draw it out, the planning naturally happens.
Hope this helps.
Superb quality work by all 🎉🎉
Thank you so much 😀
My own house has been running happily on a 2015 Tesla Model S battery BTW, its 14 blocks reconfigured in a 2S7P configuration with a separate BMS for every parallel layer
Brilliant stuff guys. This is really interesting to me because 1. I am hopefully buying a barn, and 2. I have an iPace. Not that I would donate the car battery, I think the Fogstar offering is just too good these days
Don't let imposter syndrome get you down. Ask others for everything they know and then find somebody who knows more and ask them. Very quickly you become the person with answers. Never stop learning, never stop sharing.
Thanks dude!
I'm overwhelmed at the moment. A new role was created for me to ensure legal tests are being performed correctly, but the more I look the more historical errors I find, which is also down to me to resolve.
I'm now having every Thursday off for the next 8 weeks to do what I please.
Easy to do when you have paid annual leave. Not so easy for you guys.
Well done Rob 🙏🏼. And well done for taking positive action
Very happy to see this video come out! Congrats on getting it working.
I feel that a part three showing it looking neat and powering the house would finish it nicely.
I hope we see more of these as reusing a battery is far better than not.
Great content, Cory on something that no one has tried to do., if you pull it off it will be really interesting , Well done Guys ⚡️👊🍿
We have pulled it off! Watch to the end 😁. We’re currently working on something BIG with these
What everyone preferred method to strip a cable ? As I can’t strip it without denting the copper
Sharp cutters, and lots of practice 😃👍🏼
Thanks 👍🏻
Awesome channel, appreciate the encouragement for the apprentices
Our pleasure! Thanks 🙏🏼
i am using The Nissan outlander batteries and CMU's for a second life ESS. would love to see more brands code cracked ! to support the community
Hi Cory, I'm a 4th-year apprentice. What would be your best advice to prepare myself for the AM2S?
Awesome project!
Thank you!
Imposter syndrome is a reel thing, I’ve felt that way and still do at times. But then I’m reminded that I’ve achieved real things proving I’m not an imposter.
I get how you can feed a 400V battery into the PV input of an all-in-one inverter for powering the home mains from the battery. But how are you charging the battery from the all-in-one inverter?
Is the all-in-one inverter designed for a 400V battery? or are you using a separate car charger which you're controlling form the inverter?
It’s on the battery terminal of the inverter. It’s a solax hybrid inverter, and this battery is within its operating range.
Awesome 👌
Thanks 🤗
Always good to be out your comfort zone, benn qualified for 10 years and last year move into the office as an EC&I designer in the water industry so had a steep learning curve on all the controls and instrumentation aspect of the job but thata the only way you learn by doing things youve never done before.
Nice job
Thanks!
If you ever need to terminate in an RJ45 with thin cable again, try Cat6 connectors. They made for thicker cores.
Awesome work though. Cool project.
Good idea. Can you recommend any parts/crimp tools? I'm still used to cat 5e, In the old skool era.
I'm confused, I've watched both videos, but did I miss the part where you explained how you were going to charge the battery up again after discharging it through the inverters solar panel "IN" connectors ?
It is connected to the battery terminal of the inverter. It’s a solax hybrid inverter, and this battery is within its operating range.
It can charge and discharge through this terminal
@@corymac Thanks for that - just looked at the specs - 120/800V is crazy. I should have checked first before questioning !!
Hi Cory
I loved your rant about people calling themselves ‘engineers’ especially the ‘opaque’ engineer. However I’m not so sure that I would want a converted EV battery anywhere near my house. I’m guessing my home insurance people would have something to say let alone the lady of the house. I would want it sited in a fire proof bunker. I don’t think a risk assessment including loads of mitigating things like 5+hr fire walls sprinklers, sirens fire blankets automated foam jets etc. would make me feel any better I’d just not the risk.
Yep, Its not for everyone! But still, a lithium cell, is a lithium cell, so in some applications, its perfect to use!
So looking forward to this video!
Great idea to reuse battery, but you should design your own PCB. It would save you time and most likely make it better, adapting to your use rather than redesigning a car one to make it work for you.
That's the plan!
Could I get the dimensions of that battery ??
I'm not yet an apprentice, but will be starting my electrical training in just over a month, at the age of 29 decided I needed a career shift. Hopefully will be able to join in with this community a lot more in the future. ⚡
Congratulations mate! Welcome to the gang. Hit the notifications bell, we will be producing more specific educational content in the next year
Your videos are epic ❤
No, you are, Brad!
Well do Cory and Co, great to see a hell of a problem solved, and your right its good when you start a new project and think why did I take this on and i cannot do it, then somthing clicks and you come up with a solution and it works out not to be that hard at all
Seen that batteryman has just installed and got his tesla battery almost up and running. Hes got the contractor to close and all seems good on his side.
That’s cool! What year Tesla? It seems to be getting harder with newer batteries
@@corymac 2023 model I believe. He had an issue with the lilygo by having a certain inverter set in the software that required some other settings to be done or smoething like that. His channel is @TheOfficialBatteryMan
Yay.. part 2
I admit, your idea is probably quite a bit more convenient if you are going to use 10s or 100s of EV battery packs, but if you just have one then disassemble the battery and aim to make 48v packs. Or you know, you can get LiFePo4 batteries from china for a little under $150 per kwh, so at most 90kw of batteries would cost $13,500 USD, so I would argue saying the EV battery is worth 90k GBP is a bit off when you consider the plug and play alternatives.
We’ve managed to build this for a material cost of less than £2k plus the inverter… I have a plan to make this BIG BIG very soon… subscribe and see 😉
Always a good day when one gets to watch anorher Cory Mac video😎
What a legend! Don't forget to hit the notifications bell 😉
That RJ45, do yourself a favour and buy some field termination plugs. Some have a weird numbering, something to test before with a tester. I have mine scribbled on my toolbox, 1=5, 2=4 etc...
You can get M and F types, makes stuff like this a whole lot easier.
Great for stuff like POE access points where you need to run custom lengths of cable.
I will do, thanks!
Awesome, as usual massively over my head in terms of technical know-how, but enjoyable nonetheless! Reuse and repurpose as much as possible even if the big brands don’t want you to! Well done to you all 🙌👏
Glad you enjoyed it!
What inverter are u using? Love u are using a HV inverter. How many kw? Price? Source?
Solax, got it
Love it!!! Great job!!!!
Thank you! Cheers!
Really great episode...can't wait to see part 3!
Kind hoping you guys can turn this into a 'product' that you can then replicate...is that the plan? Would love to see how costs could compare vs my Powerwall + installation.
When was an Ipace £90,000 ?
Definitely make an fireproof enclosure for this battery and have a stainless steel or at least steel 100mm vent out with draft stopper, in case of fire it vents the flame to an sefe location.
These batteries are know to catch fire when driving. Might not be an issue for only 12 Kw but still play safe. That's what im going to do when go for EV home battery 😁😅
That’s exactly what the cells are already encased within
