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.
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.
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 🙄
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 👍
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
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.
@@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.
400v and 800v batteries are not for the home mechanic. 99% of manufacturing companies won't fix these in house not alone at dealerships... They are incredibly dangerous
@@roryoconnor8674 So were old colour tv sets with 350 or more volts DC power lines, and 25,000 volts EHT. 8,000 pulsing volts on some tube anodes and other places around the TV sets in the line scanning circuits. They were incredibly dangerous too. Enough to kill you in many places, and arguably more complex than a lot of battery cells wired in series. But I used to fix them in people's houses. Diagnosing faults with the set powered and often fully functioning. Year after year these were fixed in people's houses, by countless technicians everywhere.
When you asked to comment if you have ever been overwhelmed at work I thought of a few times I have. I’m not an electrician. In fact I only watch the videos because I find it interesting. Anyway back to being overwhelmed. Every job I’ve had (and it varies from being at sea, driving HGVs, being a Coastguard, being an instructor for the coastguard, being a driving instructor and finally being an HGV instructor and driver coach) at the start I’ve totally felt overwhelmed! To the point at times I thought why the hell did I leave a comfortable job for something that is so hard. But every time I’ve felt a huge sense of reward when I have that first day of “okay I can actually do this”. That’s the point I always look for the new challenge in that job. If I can’t I find a job I can. I work to live not live to work. Enjoying the journey along the way is a bonus.
I was recently and to some extent still am feeling quite overwhelmed. I have a to do list a mile long and not nearly enough time, money or other resources to finish them all. A good friend of mine cut through my anxiety with one simple truth. Stop looking at the big picture so often and focus on what you can accomplish today. You can only work on one problem at a time, so that's where your focus should be. On one problem until it's solved and then move on to the next.
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
Just caught up with this. I have been quite pessimistic about your chances on previous post but hats off to you guys for persistence and putting in the hours to get this working. Hopefully you'll be able to give your information back to the community now so others can do the same hack. As others have said a part 3 would be great and maybe include a summary of the reverse engineering approach if anyone else want to hack other battery packs.
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
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! 🤩🤩
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
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
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%
@@obbardc Good that you are getting cell voltages from the BMS. LG's pouch cells, as in I-PACE, have a habit of tabs becoming disconnected. This leads to modules becoming 3P rather than 4P. The I-PACE BMS wasn't flagging this in earlier firmware revisions leading to the module becoming over charged, and fires.
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.
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!
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 👍🍻
Long-Term, I would be much more likely to buy an EV if I knew that after the battery aged out or the car was damaged. I could still use the battery in a system like this. If there were standards for the large volume cars instead of components, that'd be much more likely to purchase an EV.
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.
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.
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?
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.
@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. 💫🌟💥👍
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.
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.
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
How will you cool the battery? I didn't watch first part, but these have cooling systems in the cars. I saw some pipes and a pump next to it, so wonder if that is your cooling loop. Thanks,
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!
13:55 put a regular section of short cat5 cable into the connector with all 8 wires. Now strip only the ends that you need to connect. MUCH easier than to try and just put 3 wires in.
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 👍👍👍
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).
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.
I’m watching this as a mechanical engineer working inside of a major Ford plant, waiting for an opportunity to work on my machine, wondering how the heck you learned how to decode raw CAN data like that despite my machine having a device for just that inside of it. All perspective, mate!🤣🤣
@@cchallett1 I've spent too much time just tinkering with things, trying to figure out how the "big boys" do it and picked up some skills along the way. And happy enough to give anything a try....
Glad to see the correction comment on the disposal of such batteries. In no way can anyone be allowed to toss these batteries away. As much as possible must be recycled from them even after many reuses of the pack post EV use. I look forward to seeing the finished installation then a performance report x months down the line.
Having spent the last two years working on the onboard H2 production & 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
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?
@michaelridler5119 the yacht generates electricity from 3 independent sources so energy production is not the issue when the sailing conditions are good, however an ocean going yacht will have multiple times when the conditions are not met for generation of power through renewable.... a yacht that has set out to circumnavigate the world should be able to propel itself a minimum of 500 nautical miles under its own ability as a matter of safety... the battery storage capacity required for that is way to large for a sailing yacht even one at 58ft. The total storage capacity onboard is 120kw, divided 90 /30 between propulsion and hotel systems. Once our storage capacity is full the excess energy is used to produce and compress H2 to be used to recharge the propulsion bank when we are running on the electric motor for extended periods
when a battery is shredded the powder left is known as Black Mass. It sells for thousands of pounds per tonne every day; it is then separated into it's original properties i.e. Nickel, Manganese, Iron, Lithium, Cobalt and resold or reused
Everyone normal experiences Imposter Syndrome and the more experienced you are the worse it gets IME. The people who claim to be "experts" and to not experience it are often the ones you want to stay away from as their surety is often poorly placed. It's normal when something you find intuitive and have experience with is mysterious to others while they look at you like you're smart and you look at yourself not feeling worth their praise because you're just doing what you've learned to do. Teach others, it helps reinforce your own knowledge and it takes the mystery out of it for others. Anyway, I would LOVE to have a battery like that hanging on a wall for a battery bank! I'd like use a Tesla since they're damn near everywhere and there's knowledge about them but the price of most any recycled EV battery vs what battery companies charge is nutz! I'll take an EV battery in a steel case with safeties over most of the systems manufactured for purpose!
I’ll be using an old Leaf battery on my system eventually (when it’s no good for the car anymore lol). At the moment I’m using my battery ride on mower as a pack. Works great and it still mows lawns 👍🏼
Please just bypass the existing bms with one you can tweak. And yea precharge allows the load side of the main contactors to come up to voltage so they don't weld shut when they close. I spent 4 years testing the ev prototypes for hyundai motor group. CANalizer and Vector are decent tools for hijacking existing CAN signals.
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
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
Two points from the video. First, I'm a Chartered Engineer and feel the word Engineer does get banded around too much 😂 second, I've been been overwhelmed and it feels endless sometimes. I tell people, get a coping strategy and move forward 😊
Hi guys, I'm currently an electrical engineering apprentice just outside of London working in a industrial factory , have a question, can someone explain to me why don't they use the same bus system, like cars have CAN and houses have RS? is there a specific reason or just personal preference? Also I know PLCS like the ones from siemens also use bus systems but again different?? Thanks guys Ps cant wait for the care package aha
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 ?
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?
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.
I'm just under half way through the video but, would it be easier to just rip out the entire BMU and find a programmable one which you can tell how the batteries are wired and the total storage capacity?
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!

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.
@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 😂
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!
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.
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 😁
How will you cool the battery? I didn't watch first part, but these have cooling systems in the cars. I saw some pipes and a pump next to it, so wonder if that is your cooling loop. Thanks,
Your not pulling or charging enough power to heat these up just a 5kw inverter with probably 2.5kw charging capability
Well done, well done indeed. That canbus hack is nothing for a weak soul.
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!
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.
13:55 put a regular section of short cat5 cable into the connector with all 8 wires. Now strip only the ends that you need to connect. MUCH easier than to try and just put 3 wires in.
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!
Keep Chris around he’s goat value I assure you!
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...
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.
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
Absolutely love this content, inspirational 👏
Glad you enjoy it! Thanks for the comment 🤩
Great result - and importantly open source for others to benefit 🎉👍
This was just so awesome. Respect for making this.
Thanks dude!
Well done very impressive
Been waiting for part 2 for so long!!!
Worth a part 3?
"Surround yourself with people who are better than you"... Cut to me... You must be joking 😂😂
Just a coincidence 😝😉😉
I’m watching this as a mechanical engineer working inside of a major Ford plant, waiting for an opportunity to work on my machine, wondering how the heck you learned how to decode raw CAN data like that despite my machine having a device for just that inside of it. All perspective, mate!🤣🤣
And I should say I’m not a driving instructor I suppose.🤣
@@cchallett1 I've spent too much time just tinkering with things, trying to figure out how the "big boys" do it and picked up some skills along the way. And happy enough to give anything a try....
Now add a second battery, Dala's updated the firmward or hardware for that I think.
Glad to see the correction comment on the disposal of such batteries. In no way can anyone be allowed to toss these batteries away. As much as possible must be recycled from them even after many reuses of the pack post EV use.
I look forward to seeing the finished installation then a performance report x months down the line.
Amazing job! Very pleasant ro watch with the good explanations. Well done.
interested to see voltage details of the battery minimum , maximum... and solar charge controller / inverter , link s please?
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.
Whooohooo!!!!! You guys are awesome!! Congrats!!
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!
Having spent the last two years working on the onboard H2 production & 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?
Because H² at 300 bar is 15% the cost and weight of batteries at the same capacity?
@@michaelridler5119
@michaelridler5119 the yacht generates electricity from 3 independent sources so energy production is not the issue when the sailing conditions are good, however an ocean going yacht will have multiple times when the conditions are not met for generation of power through renewable.... a yacht that has set out to circumnavigate the world should be able to propel itself a minimum of 500 nautical miles under its own ability as a matter of safety... the battery storage capacity required for that is way to large for a sailing yacht even one at 58ft. The total storage capacity onboard is 120kw, divided 90 /30 between propulsion and hotel systems. Once our storage capacity is full the excess energy is used to produce and compress H2 to be used to recharge the propulsion bank when we are running on the electric motor for extended periods
when a battery is shredded the powder left is known as Black Mass. It sells for thousands of pounds per tonne every day; it is then separated into it's original properties i.e. Nickel, Manganese, Iron, Lithium, Cobalt and resold or reused
Everyone normal experiences Imposter Syndrome and the more experienced you are the worse it gets IME. The people who claim to be "experts" and to not experience it are often the ones you want to stay away from as their surety is often poorly placed. It's normal when something you find intuitive and have experience with is mysterious to others while they look at you like you're smart and you look at yourself not feeling worth their praise because you're just doing what you've learned to do. Teach others, it helps reinforce your own knowledge and it takes the mystery out of it for others.
Anyway, I would LOVE to have a battery like that hanging on a wall for a battery bank! I'd like use a Tesla since they're damn near everywhere and there's knowledge about them but the price of most any recycled EV battery vs what battery companies charge is nutz! I'll take an EV battery in a steel case with safeties over most of the systems manufactured for purpose!
Wow! Brilliant, well done.
Glad you liked it!
Great video, well done
Thank you very much!
Well done in getting it working
Good job. Cool stuff
Superb quality work by all 🎉🎉
Thank you so much 😀
Awesome channel, appreciate the encouragement for the apprentices
Our pleasure! Thanks 🙏🏼
Great series! Love watching the videos. Idk if the 6 unilite apprentice care packages have been taken but I’d love one!
I’ll be using an old Leaf battery on my system eventually (when it’s no good for the car anymore lol). At the moment I’m using my battery ride on mower as a pack. Works great and it still mows lawns 👍🏼
Brilliant work well done 👍🏾
Please just bypass the existing bms with one you can tweak. And yea precharge allows the load side of the main contactors to come up to voltage so they don't weld shut when they close. I spent 4 years testing the ev prototypes for hyundai motor group. CANalizer and Vector are decent tools for hijacking existing CAN signals.
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!
What's the 0-60 time?
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
3:00 I love that call-out, "Apprentices Only -->", and then you zoom in to all your most obvious faults ;-)
Excellent, well done.
Many thanks!
Two points from the video. First, I'm a Chartered Engineer and feel the word Engineer does get banded around too much 😂 second, I've been been overwhelmed and it feels endless sometimes. I tell people, get a coping strategy and move forward 😊
@corymac, what work trousers are they?
Awesome project!
Thank you!
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
So when can we see a kit available for this?! Nice to see the persistence has paid off 🔆🥳🥳
Hi guys, I'm currently an electrical engineering apprentice just outside of London working in a industrial factory , have a question, can someone explain to me why don't they use the same bus system, like cars have CAN and houses have RS? is there a specific reason or just personal preference? Also I know PLCS like the ones from siemens also use bus systems but again different??
Thanks guys
Ps cant wait for the care package aha
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
Awesome 👌
Thanks 🤗
BROWN, BLACK, GREY. !!!
Wonderful project guys :-)
What inverter are u using? Love u are using a HV inverter. How many kw? Price? Source?
Solax, got it
Thanks for giving sources, I suspect the reason is that currently very few packs are totalled as worthless and sent for disposal?
Hi Cory, I'm a 4th-year apprentice. What would be your best advice to prepare myself for the AM2S?
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 !!
I had the same question, had to scroll a while to find this. I had no idea there was an inverter that could have that as the battery input voltage
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.
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!
Can wait for a summary Pt3
Nice one guys
I'm just under half way through the video but, would it be easier to just rip out the entire BMU and find a programmable one which you can tell how the batteries are wired and the total storage capacity?
