You stayed positive and the miracle happened with all your good will and knowledges. Congratulations, I didn't have any doubt you would be able to solve the problème. Thumb Up.
If anyone could've done it, it'd have been you. Never a doubt!!
Woohoo that is awesome Dala, so pleased you were able to sort this out.
We could hear the relief when you fired it up, nice that it's gone well. 😊
It’s all completely above my head, but very interesting, so glad you managed to fix the replacement battery. I drive an E Niro, love it but wouldn’t have a notion on how it works just glad it does. It’s great that there are so many people out there that are willing to help.
Fully agree, the community around EVs are awesome 😁
Fantastic! Very informative. Good job!
It's neat, the back row modules alone are similar capacity to an original whole 24 kWh battery pack! Best of luck! My 62 kwh pack now has 45k miles in the 2014 car, and continues to look good. We'll see!
How much range do you get with a 62kWh pack in a 2014 Leaf?
Excellent news Dala. 😊
Finland 1 Vs Leaf Battery 0. Conrats Dala!!!!!
Hi Dala,
I am really happy for you. Greetings from Colombia
Just a note on safety when using insulation meters. They output high voltage to perform the testing. Usually wise to wear high voltage rated gloves. At a minimum be very aware of any capacitors in the thing you are testing. I am more familiar with Fluke equipment, but there should be a voltage presence indicator. Be safe and have fun!
Good tip!
Well done for sticking at it. 🙂
Well done.
Great work. You should do a full 1000km run in one day! Congratulations on making the battery work! Hard work paid off!
Wow, great to hear it's finally resolved. 👏👏
Really pleased you got everything sorted and have a good battery now.
Awesome! I'm getting ready to replace my 2011 Leaf battery this fall....thanks for the inspiration!
Me too, here in the Pacific Islands. First we have to drive over coconuts and I cant see how to raise the ride height with the existing springs?
excellent job! congrats and thanks for sharing the process!
Greetings from the Technical University of Denmark (DTU)
I don’t drive a Leaf, however I followed your videos with interest. Many thanks!
Thanks for watching! :)
Hey Darla,
you did a great job! And I really think that we would need much more people like you that keep older EVs running!
Like you've already mentioned batteries with an issue at just one pack "others" usually through away. What a waste of resources.
Anyway, the M12x1.25 is a common machine thread (machine screws) and also common on Italian cars, just if you should need spares.
We call it a megger test in power plants. On power plants we usually go by 1Giga ohm per 1000 volts on megger.
Well done good work and thanks for the video!
Thanks for watching! 😁
Bravo. Real engineering 😅
Congrats. Enjoy your new long range leaf
Wonderful news !
So glad you got it fixed 👍
Me too 😂 Thanks for watching!
Totally Amazing work well done Dala .
great work! nice to see that it all worked out. 💪💪
Fantastic the Leaf is all good 👍😉💪
Really good video glad it all turned out well
I'm so glad that it all worked out! It must have been so stressful to think that you are wasting so much time and money, but it all worked out !
So happy you got it fixed I have a 2020 Leaf 62 KW Love it,
This is filled with great insight into the modular nature of these batteries. When I watch it I’m thinking about the future modules that might be on the market and what I’d have to do to get them to fit and work in this shell.
It would have to be simulated to withstand a 150km/h crash without shorting the modules together and burning to the ground. I'd stick with OEM cells over a DIY job anyday!
@@DalasEVRepair Does the company that makes these modules still exist and will they bother to make modules using old chemistry tech ten years from now? Unless we want to junk the leaf we will need universal solutions.
Great
Happy for you Dala :)
Here watching Dalatube while my 62 swapped 2014 Leaf fast charges. Yikes i saw 31E7 here. No that's not the code I've seen, whew!! Recently i came across two 9s modules to use for stationary storage, and as spares if my pack ever needs. Hope your enjoying your 62kwh Leaf Dala!
way to go Dala! Nice job fixing the broken pack!
Nice video!
Nicely done!
Ei voi kuin ihailla sun ammattitaitoa. 🙏👍
Great job 🎉🎉
You are the man. I bet there is no Leaf issue you cannot deal with :)
pondering about buying a second hand leaf but my daily commute is 100 km , cool that you have a 100nx had one years ago enjoyable car to drive but easy to trip speed cameras
Great news! Got us worried there for a bit. Congratulations 👏
Well done. One question I'm curious about what was exactly wrong with the faulty module. Did you not try to open the module up and see where the short to the ground is.
Brilliant, well done! So happy it ended well.
Congrats! Happy to see that the module swap worked out! Just in case, keep monitoring it regularly because my issues came up when I reached very low voltages.
Great work Dala, 👍💪✌️
Congraulations Dala, as we say in the UK if a job's worth doing, it's worth doing well. You persevered and got there finally.
Thank you for sharing all the work you've done.
Loistavaa duunia. Joko vihdoin Chademo / Ccs retrofitin kimppuun?👍
Yessss viihdoin se jatkuu!
Nice Dala. Congrats on the new replacement and project finished 🎉🌭🍺😁
Awesome news Dala, glad it turned out well for you ! Out of curiosity, how did you get a hold of the used cell ? I know they are next to impossible to acquired directly from Nissan. I even inquired directly from Japan and they would not ship.
Sorry I cannot share that info, the source wanted to stay anonymous!
Love it. Kudos, Dala from the future!
Well done and congratulations on getting that sorted out.
Thanks for watching! 😁
Amazing job! For what it's worth, the stuff you glued the battery case with, I'd call sealant or silicone but glue makes sense. Thanks for sharing, keep up the great work!
Nice job!
Super congratulations brother your smart and hardworking in your battery pack
Great job, Dala! So happy for you!
The sikaFlex has many types of silicone that helping shield various of applications... A typical one like that you are using is perfect for these applications. But I don't know how will be after some heavy winters. A regular silicone can not shield like that ...
U r the best !
Thank u tremendously for your continuing work and videos!
Well done, Dala! 🙂👍
Excellent work, and nice choice of stopping at Roadhouse. It's always a blast to see an American mall somehow teleported into the middle of the Finnish forest.
A note on the insulation meter, though: I'm not sure how accurately it will read, since the leak wasn't at either end tap (you had 12 V from one terminal and 24 V from the other, so the leak must be between one of the middle cells and case). So there'd be a 12/24 V DC offset on the measured result, which might confuse the meter on a bad day. It'd probably still read close enough to give you a pass/fail, but it's worth keeping in mind. I usually try to look at the test current readout if it's present on a meter rather than the megaohm reading, since there's no internal meter logic involved in calculating that value.
I suspect the electrolyte dried up or shifted, which removed the leak to GND entirely. I need to do some more digging when I have time for a postmortem
This is so amazing, congrats on keeping faith and pushing forward! I am super nervous about doing this replacement myself, I would love to have a first gen leaf with 260+ miles of range! I have decided to stick with a 40kwh pack for mine for simplicity, but dang that range is super tempting! Can I fly you to Montana in the USA to help me lol. Thanks again for this video, and your others, and I am beyond excited to get my leaf (it's being delivered as I type this, less than an hour and I will have my first all electric vehicle!).
Good luck with the upgrade! 😁 Be sure to read the wiki: github.com/dalathegreat/Nissan-LEAF-Battery-Upgrade/wiki
@@DalasEVRepair thank you!
Job well done boss.
great thanks
Good wish you many future miles congrats
Well done Dala, awesome work as always
Whee! Gratz! I am super happy for you. And I can feel how happy you are. You are radiating :D
Dala, say something stupid happens during quick-charging and for whatever reason you torch the car next to you. Are you not afraid that the insurance will not pay, if something bad happens? If you ask Nissan, you basically put the wrong battery into the car.
Also, the charge cables with the spirals on top reminded me a lot of petrol stations. I got quite disoriented there :D
Cheers!
Exactly the same thing as if someone replaced their fuel line on an ICE car, and it torches down a garage. Insurance covers.
Amazing Dala. Really diligent work. Did you bash the dent out of the bottom casing? Are these packs vulnerable to impact from underneath?
Yeah I bashed it out (1mm dent), but there are so many mm's of tolerance that it would not have mattered. They are double walled metal, so very strong casings.
Dala,pass me the popcorn pls
Nice
Bravo ❤
Fantastic news, and you are really fortunate to get hold of a used tall section bank, may i ask what breakers you used to buy it and how much it cost? usefull for us to see what is available in the used battery selling dealers in case we need to try to find replacements ourselves. Great work Dala.
Sorry I cannot share that info, the source wanted to stay anonymous! But the rough cost is 1/6 of what the NZ company that stocks the modules take for them!
@@DalasEVRepair understood. Hope it was cheap though, as you deserved abit of luck. Do you I tend to try to find the source of the problem with the original stack, could've an easy fix and put the stack back into use, Shane to let it sit unused
@@anthonyevans7911 It is spotwelded and re-assembling it wont be easy (or safe), so best suited for another project :)
Would be great with a final summary of how your leaf is doing now :)
It is doing awesome! Got some more performance mods planned for the summer 😎🌴
@@DalasEVRepair Looking forward to that! And too see how the new battery is holding up so far :)
It's good 👍
Well done Dala.
Ive got a broken 62kwh pack that could do with a new cell/ module. Seems to be the same module area… how does one source these? Cell 44… 13:25
Holy Wow
Great news. I watched your videos to find out how future proof is to buy an EV now and upscale the battery in say 5 or more years. Do you think this is just a Leaf perk, or is it common for other manufacturers as well? Or even better, how would one dig this information out?
You should not have to change the battery of a 2023 EV basically ever. If you buy a car with good thermal management and good enough range to where losing 10 or 15% to degradation isn't a big deal, then the battery will outlast the useful life of the vehicle. The leaf has neither. That is the reason why it is so popular for modding: if you've 60km of range left, then replacing the battery starts making a lot of sense.
Nice!
I wonder if the earth leakage was just due to moisture ingress? It's possible that in the collision, the seal was compromised.
If so, maybe the module you took out is actually OK?
I had similar issues tracing a small leakage current in my DIY EV & it turned out to be moisture bridging one terminal to ground.
So the old module seems to be ok after sitting for a while, hmm. If it was charged and discharged, maybe it would leak again, probably. Maybe it could be reused for something like a ~36v old lead acid lawn tractor (GE Electrak), 9s would work fine.
Now you got me thinking 😂
Great result. What happened to the old module - did you figure out why it was throwing that error code?
Why did you bother to 500V test both positive and negative terminals to ground? I'd assume that if the internal impedance of the battery is somewhere around normal then these terminals would appear as a short to the 500V impedance testing meter. Am I missing something?
Could be a diode or a failure of the circuit that only interacts with one side of the circuit. The high voltage system is entirely isolated from the low voltage system so the negative and positive terminals an the batteries should have no connection to the case.
@@juancarrera5524 Yes, thats right, to ground should be high impedance but the negative and positive are a dead short (a few milliohms) to each other. Any component in parallel with these terminals will be swamped by the short between the posts. So for the purposes of a mega test, either positive or negative terminals will give the same reading.
Most likely it is leaking electrolyte fluid. Hard to say without tearing the module down further, and it is spotwelded together!
@@DalasEVRepair I know it would be hard to pull apart and quite fruitless. Just asked in case you had a clue about it and obviously you do. Thanks Dala
Too bad they are spot welded, very difficult to service, shame on Nissan for that!
What was the brand and model # of the multi-meter that you where using for the 500V? Nice video.
Thanks! UT505A Uni-T
why are you using leaf spy nor original diagnostics program? You know Kaljo from Estonia? Thanks for info man !!
Consult3+ requires license and is €€€€ to maintain. Leafspy is €€.
Well done, your dash shows 434 kilometres range. I have a 2022 62kw leaf & I get 330 kilometres on average, what's your best, worst and average range?? Sorry for all the questions.. Paul
Well my leaf is quite inefficient, no heatpump, big 18" wheels with bad aero, so I don't think it should be used as a reference for anything 😅 but 300+ is doable
❤❤❤❤typical Dala will find a way... This is the way... 🎉🎉🎉🎉 Great...
Mukavaa että tuli kuntoon. Joku siellä jo kommenttia heittikin että ei kannata varmaan kaupan kovimmalla liimalla välejä tiivistää. Jos tuon liimaa jollain isältä pojalle tyylisellä liimalla niin on varmasti mahtavaa jos joutuu aukomaan. Tiivistemassoista ehkä video? Pyydät vaan sikaflexin kaupalliseen yhteistyöhön. Löytyis mikä on hyvä tuohon hommaan.
😂 jo ei kannattaa käyttää liian vahva liima!
your car insurance will also be happy, since they can refuse any claims in the future
Kämpar på med min 2016 30kWh. Nu 151 000km och 9 bar. Garantin går ut i januari. Skit om den inte slår om till åtta innan Januari. Surt
Snabbladda varje dag, kör så mycket som möjligt!
@@DalasEVRepair Står och pressar vid 50kW laddaren på väg hem. 92% och den ger 6kW nu och 43min kvar till full. 🤷♂️✌️🤣
Brawo 🎉🎉🎉🎉🎉🎉
Realy good film.
What is the price on a battery swap 30Kwh to 63Kwh?
5-8k for 62kWh packs!
I’m very close to buying a 2014 leaf with original 28kw.hr battery and importing a 62kw.hr using CATL cells.
Tell me why this is a good or bad idea?
I have to say that watching your video makes me want to try replacing mine with another 24 or 30 pack into my 2012. Was it hard to do?
Think hardest part is sourcing a battery!
Hi dala
I have error p317d in jac s4 ievs4 it's discretion is monomer balsting but i checkd by multimeter and charge, discharge all cells working fine but the car getting ready without press break pedal and charging maximum 8 K/wh
Appreciate your help
Dont know how the spy works, can you se the batterystatus when you drive? If you stand still with no load
the batterycell ofcourse show similar voltage. If you can see the cells driving the car, then it realy shows
the condition on the batteries. Congratulation to the repair.
No sudden drop under heavy acceleration! Max 50mV diff!
Why is your Hx so high 102%? Mine is only about 85%, even when new on my 2023 Leaf SV Plus.
Now you should do a full range test to see how it differs from the 2nd Leaf generation.
My LEAF has added noise insulation, bitumen pads, 18" wheels with phat 225 tires, no heatpump etc. It is very inefficient. I probably get 325km realistic range out if it.
How do I get access to Nissan technical notes?
I have a battery replacement kit coming. Need to check my as much technical data as possible
Full service Nissan Leaf manuals are available on Nicoclub
I'm confused about the original issue, it seemed like you tested the old one, but it had good 500MOhm resistance. so isn't that fine?
Most likely the leaking electrolyte shifted/dried up. Massive risk it comes back after a few charge cycles. Replacement was best longterm option
