Capacity test VW id3 id4 battery module
Вставка
- Опубліковано 1 жов 2024
- A simple test that i did with some stuff that i had at my home.
Start cell voltage: 4,15v
End voltage: 3,4
Ah Capacity: 156
Nominal voltage 44.4V
Type Pouch Cell LG Chem E78 - NCM 712
Cell Manufacturer: LG
Cell Capacity per battery: 78 Ah
Cells in a complete Module: 24
Module Circuitry: 12 in series, 2 in parallel (12s2p)
Module Capacity: 156 Ah
Length 590mm
Width 225mm
Height 110mm
Mass 32kg
Bolt Size M6
Charge voltage cut-off:
Cell = 4.2V
Module = 50.V
Discharging cut-off:
Cell = 3.3V
Module = 39.6v
Maximum Discharging Current (10 sec.): 800 Amps
This is amazing - 6kWh from one module is perfect - great home storage solution. I wish there was some off-the-shelf solution to get a salvaged battery from crashed VW MEB platform car, hook it to some coolant external circuitry, plug in into the battery and off you go - home storage ready. With some good 3-phase inverter, you might get dirt cheap and quite big home battery with high reliability.
Maybe you can try at Second Life Battery. This is a Spanish firm that sells reclaimed car batteries. Maybe you can find VW batteries there.
Great video, really clear explanation. Really good battery power that packs achieving. I was wondering if you might be able to help me please. I have the same BMS but with the older NCM622 cells from a 2019 hyundai ioniq. I have seen your upper and lower charge and discharge voltages are set at 4.2v and 3.3v. Only issue I have is if the voltage drops so low on a 12s configuration, will the inverter still work and push the power out? And will it then kick back in to charge them back up. I've had issues over the hybrid inverter not wanting to charge the batteries if they run low. I've decided to order the power meter your using to try to understand my actual capacities. Many thanks, David from the UK
Hi David and thank you so much. That is a very good question you have there. That is one of the biggest problem with this inverters from growwatt. You are not able to set the voltage lower than 40 volts, then it will cut off the power and also when you’re going to start to charge a battery like this, it took almost 5 hours for the inverter to ramp the amps up so it’s actually start to charge the battery again. So I highly recommend Victron because I have heard that you can set the voltage there to a lower setting and also a lot higher than this Growatt inverter I think it was 36v and all the way up to 63v so to use this battery together with a growatt is highly NOT recommended .
Thank you so much for your comment and have a fantastic day☺️
@@flyingtools Thank you for that. Maybe when I have some more money next year I will upgrade to Victron. They're quite expensive but as you have mentioned, a lot better than the cheaper Chinese inverters like my hybrid inverter charger. Otherwise its probably cheaper just to buy a cheap Chinese version of the tesla Powerwall and just negate all the uncertainty.
You have a great day too please 😁
Wow, de är ju fantastiskt, 6 kw från den där lilla lådan! Mitt 10,8 kw batteri måste vara minst 5 ggr så stort. När jag fått mina ytterligare 10,8 så är den ju som en mindre garderob i storlek.. Vet inte om jag missat något, men varför bygger du batterilagret på en släpkärra? Är tanken att de ska kunna fungera som räckviddsförlängare? 😃 Som vanligt, tack för att du delar med dig av de du gör!! 👍
Hej. Ja dessa batterier är verkligen fantastiska. Jag monterar allt på ett gammalt husvagnschassi som jag bygger om, fler filmer kommer om det längre fram den bara råkade komma med i förbifarten den här gången. Tanken har slagit mig som räckvidds förlängare 😅 Jag måste ha något hus till batteriet så varför inte bygga det som man kan flytta det smidigt.
Stort tack för ditt intresse för vad jag pysslar med😃👍🏻
😊 I believe that you have a voltage drop on you wire that will make up for your losses.
I think you have full capacity on your battery pack 😊
Always nice to know what capacity you have in your battery👍
I made a comment on your last video, only thing I forgot to tell was, the reason for a small fuse in the cell is due to safety.
If the battery is shorted on the balance lead it will turn in to melted wires, because of the resistance in the wire and the low voltage makes it impossible to blow a fuse at 5 Amp. I used a faste acting fuse at 250mA and 0.5 Square millimeter wire, that works out, with out a fire. 😊
Yes, you are probably right. But I rather just mention the numbers, I don’t want to overestimate it.
I saw that comment and I know about the fuses and the reason why they are ther, I was just hoping they they will hold up for a 200ma balance current so I can use Orion bms to my battery.
200mA is more then enough just as you say. I meen look at my pack without a bms, 6 month of use and a daily cycling
And a delta voltage over 108s at 8mv!!
If a battery need a daily balancing you simply have a battery with bad matching cells or just bad cells.
Thank you so much for your very informative and giving comments.
🤩👍🏻👌🏻
Perfect thanks. instead to use the battery id.3 with all 9 modules in series (about 430v) then 108 cells, which bms did you use or do you recommend?? thank you and I wish you a HAPPY NEW YEAR.
I use daly, and I will try to make a video about that as soon as possible.
Thank you so much, and a HAPPY NEW YEAR to you to sir😃✨🥳

Hey Mr. FT, i do you think it would be safely possible to use two MEB 8S Modules in series to be used on a 48V Multiplus II, using a single 16S BMS ?
Thanks for your work and the great effort!
Hi😃
Yes, that will work perfect 👌🏻
Just be aware of that you will not be able to charge them up to 4.2 V per cell, but that’s not needed anyway. Thanks for your question.☺️
Riktigt bra test! 😃👍
Det låg tyvärr inget batteripack under granen i år, men det står definitivt på önskelistan 😅
Tack😃
Aj tusan.. Nej jag har hört att man måste vara snäll också😅 Skämt åsido,
Stort tack för att du kollade😃👍🏻
WOW, that is a nice module , how did you get a hold of an ID4 module ? I need to keep an eye out of some of those. Great Video
Hi!
You can buy them from here:
www.secondlife-evbatteries.com/products/vw-id3-6-85kwh-44v-156ah
I bought a complete battery at the junkyard to use for solar storage.
Thank you so much sir 😃
@@flyingtools Wow. Thank you very much
Hello, I follow all your videos from Italy, I too have a 58kw id.3 battery that I want to use, but I can't find 12s li-ion bms, only 13s-14s- etc, but no 12s, can you show me the link where to buy a 12s 48v? thank you.
Hi!
Glad to have you here😃
I bought it from AliExpress from this seller. I have bought 9 BMS from them without any problem. You have to order a lifepo BMS and leave a comment in your order that you want it for li-ion. It’s the same price. They ship in a week, so not super fast but you will have it.

Hope this helps.
Good luck with your project😃👍🏻
Use JiKong smart BMS, 8-20S you can use it for any setup starting from 8 cells in series, it does not have any restrictions like Daly or other that require certain amount of cells to be connected
@Flying tools Do you think about make another HV battery from 48V VW modules ? You can switch between two HV batteries connected to the HV hybrid inverter. Have a nice day!
Hi. Yes, but it is pretty expensive. I have done this with an e-up 16,8 kWh hv battery when I hade to do work on the id3 battery. Have a nice day and a happy new year 😊
@@flyingtools Thanks ! Also happy new year!
Hey nice video again :) do you have put 9 daly Bms om your id3 battery? I think there are A lot of people like To see what this looks like on your battery. How you have connected them
Thanks☺️
No, daly is not to recommend in a HV system. I will use Orion BMS for that.
However, I will post a video how I connected the bms to the cell module for use in a 48v system.
Do you install the orion bms yet? That is A Nice bms to see. But also verry expensive Do jou dont want to have the orginal bms vw with A master bms that can communicate with solax and orginal slave bms?
Sir Sweden is cold country any important of battery parformance
Hi. Yes, we need thermal management to our batteries the cold days.
Hi, what's the battery connector name, where you put in a cell wires? Can't find a name, using regular Dupont connectors, but its not secure.
Hi, you will find the part number here in this video at 4,45

Thanks for your question.😃
Hvordan har du monteret bms i batteri 😊
Tänkte göra en liten video om det framöver där jag visar hur jag kopplat in bms till modulen.
What is the module voltage of 55kwh VW ID3 pure performance battery?
44V
@@flyingtoolsGlad you provide the specifications in the video description box.
where did you find the pinout info for the BMS wiring???
I measured it up my self. As soon as I have an 8s module I will do a video about it to.
Link to where you ordered the bms :D
its a jungle with the daly bms, most say 12s only has 36volt
I just posted a video about that. You will find the link in the description.
