Audi e-tron 55 95 kWh complete teardown and a deeper look in to all the components.

[@jamesbeckett4390]

I have the etron 55, it's an awesome car. As an electronics guy it's great to see what's inside. Thanks.

[@flyingtools]

Tank you for watching and for your comment 😃

[@Jorgetrader]

etron edition 1 owner here. This is great, thank you

[@flyingtools]

Thank you for watching ☺️

[@awerskto]

Super material!. I use these modules myself in RV. To be exact, I have two such batteries. In case of problems, I also have the option to combine them into a 6S pack and use them as a power bank for offgride.

[@flyingtools]

Thank you so much. That’s a good option.👍🏻

[@milan2931]

I have an etron, so thanks for the look inside :)

[@rklauco]

This is amazing. Can't wait for the build.

[@A2an]

Look forward to see the build 👍

[@michael931]

For anyone interested, the main contactor shown at 16:30-17:00 appears to be TE V23720-A0001-A001.

[@flyingtools]

Thanks for the info.

[@vulcan4d]

Amazing. Now can you explain why only 85kwh is usable? On top if that you charge to 80% so now there is 1/3 of the battery that wont be used.

[@flyingtools]

No batteries last for ever, of course, but staying proactive and aiming for 80% charge can help them last longer. This is because the battery finds it easier to charge when it is slightly empty, rather than nearly full, and therefore has less stress within its charging cycle.

[@mondotv4216]

Also it doesn't mean you can't charge to 100% - you can. And you would the night before a long trip. You just don't want to leave your NMC battery @ 100% too often as it shortens the lifespan of the battery. 80% is enough for most drivers to handle 99% of their driving needs. On a road trip you generally only charge to 80% to save time as it takes almost as long to charge that last 20% as it did to charge the first 70%. But if you can, charging to 100% occasionally won't hurt the battery. The 5% at the top and bottom is just to protect the battery. Discharging a battery fully and then leaving it empty can result in permanent damage to the cells so manufacturers like to avoid the very bottom and very top of the charging curve.

[@75L48]

Awesome, do you have a video of opening it from the bottom side? I´ve e-tron that hit some debris on a road, car got slightly banged up on its bottom plate.. wouldnt be a problem but it started to loose colant. From Audi documents I see there is coolant plate sandwiched between this lower pan and battery itself. You think that can be undone in the car? Thanks.

[@davebutler3905]

Impressive how you can work out the main components in that "brains" unit. Have you seen the super capacitor "batteries" they are fitting to some of the small hybrid cars? Regenerative braking can charge them in a minute.

[@flyingtools]

Thanks 😊 I haven’t sen them yet but I hope to learn more about that type of battery.

[@free_spirit1]

Thanks for showing us this!

[@flyingtools]

I’m glad you liked it. Thanks ☺️

[@tomasis7]

intressant! Var köper du batterier i Sverige? Jag blir nyfiken på begagnade priser.

[@flyingtools]

Hej! Jag har köpt mina batterier via bildelsbasen, några i Sverige men de flesta i Norge. Gick bra att förhandla priset för ett år sedan men idag ser det nog värre ut med det. Kul att du tycker intressant. Tack för din kommentar ha det gott 😊

[@Grejarlite]

Intressant film! 😃👍Såg du sprickan i busbaren vid 9:21 i själva svetsen? Vill helt klart se fortsättningen! Är otroligt sugen på något liknande! 👌😃

[@flyingtools]

Tack 😃 Ja, men det är troligen mer konstruktionsbetingat än ett fel i sig. Kul att det uppskattas 😊

[@msds1502]

Do you have list of component names / part numbers for Battery Junction Box or Master BMS pcb? from 13:30 onward

[@flyingtools]

Hi! No, sadly not. And I do not think that Audi have them as separate spare parts anyway.

[@viper316]

Great video. Can you do a deeper disassembly into the BMS and the battery pack?

[@flyingtools]

Thanks. It’s a little hard to do that now when I don’t have all the parts to it anymore😅

[@RichardSteigmann]

Very nice video 👍 Did you remove the battery from the neighbour's car 🤭 or did you get it as defective?

[@flyingtools]

Thank you 😃 Haha, no I bought it from a crashed car.

[@JeremiePiro-p3c]

Hi Thanks a lot for this very nice video ! Can you explain a bit more on the current sensor used normally in the battery junction box?

[@flyingtools]

Hi and thank you.😃 It is a shunt type current sensor. Sadly I do not have more information about it. Thanks for your question 😊

[@RikiLanyon]

Hi can you please advise if the accident related "pyro" fuse is in the box with relays etc inside? That would be a great help to know where it is. thanks!

[@flyingtools]

Yes, it should be there, i will take a look at that tomorrow, i missed that when i did the video. I come back to you later.

[@flyingtools]

Hi. I looked at it today and I removed everything inside of it an no pyrotechnical fuse is located inside of this relay box. I have to say that I was I little surprised.

[@RikiLanyon]

@@flyingtools Thanks so much for looking at this for me. Great informative video by the way, very interesting!

[@blusox78]

Looking at the amount of space some of these batteries have around each cell I'm surprised that they are not engineered to have a douse port, like Formula E cars, that a fire engine can connect to externally and totally flood the battery with water. Cooling the cells in a fire is the key to putting them out.

[@flyingtools]

I think it is a danish company who have developed some kind of drill that the fire fighters use to flush and cool the batteries in case of emergency/fire. But I have been in the same thoughts as you there. Thanks for your comment.

[@haykkhachatryan4386]

After the crash something happens to that module 4KE915253F car won’t go or charge and you have to replace it or it is possible to repair ?

[@flyingtools]

Do you have a crash error code in it? If so I think you need to replace it. But I’m not 100% sure. I couldn’t find any pyrotechnic fuse inside it so probably “software” fuse. Pretty stupid if so… Hope you can repair it.

[@markohare7747]

Hi I’ve bought a damaged repairable etron. I currently can’t get it started as I’m told the pyro fuse is causing it not to start. Have you any idea what part or module I need to change? Where it’s located? And can this be done easily?(diy)

[@flyingtools]

Hi. I didn’t find any real pyro fuse inside of this unit. I actually think that it is all made up in the software after the crash signal from the airbag ecu, so you probably need to change the battery ECU or the hole control unit to get rid of this problem…, and then you have to go to your dealer and have this unit programmed to your car.

[@petergrayson9947]

Hi, did you manage to see the location of the Pyrofuse? Looking on forums they're saying its inside the battery module, but i couldn't see it in your vehicle. Many thanks!

[@flyingtools]

No pyro fuse inside this battery, or I can’t not find any, and I have tried 😅 So probably only software.

[@TheJaoMing]

@@flyingtools Yes there is in the BMS module housing, you did not get to it in the video. In case of a crash you have to replace that one. Is yours still ok or not? I have a e-tron for sale here where I live and I am thinking of buying it as the prices are quite cheap because of this fuse location problem. :P

[@flyingtools]

@@TheJaoMing no physical fuse, just software then I guess. No I do not have it.

[@richardmarkham8369]

What does a battery like that cost where you are? In the UK a 90kWh Jaguar I-pace battery costs £9,000. Although I have seen some for £4,000. Yuo have to take a risk that all the cells are ok, 90kWh for £4,000 is pretty cheap compared to EVE prismatic LiFePO currently about £2000 for 15kWh with BMS in a case, new.

[@flyingtools]

Around 1000sek/kWh

[@richardmarkham8369]

@@flyingtools OK, so similar, maybe slightly cheaper. £7k.

14:30 - Not the master on this assembly - the Battery management control module is separate in the GE E-tron / Q8 E-tron, right hand side lower A pillar vehicle interior (J840). To be fair however that unit (switching unit SX6) does deal with alot of stuff including current measurements, isolation resistance checking etc....

I'm also in Ireland... Not much solar this time of year is there? I had to turn my wee off grid system off... To save power and the batteries.

[@jamesclifford194]

Hello, I will be buying a used Jaguar I-Pace pack which is similar to this one. I will be trying to reverse engineer the battery pack to use the BMS. Have you done any work on this yourself? I believe the modules each house 2 temp sensors and have 3 cell taps for connection to the BMS slaves that then network to the BMS master.

[@flyingtools]

Hi. Sadly I have no idea how those modules are configured.
