The maximum current is of course dependent on how thick busbars are, what the cells can handle, but nowadays it's mostly about cooling, as most cells are capable of high currents (nowadays the race for the fastest charging vehicles) The highest power production pack I've seen personally: PHEV pack f...

Yeah that's kind of hard to see when you have to bid on a battery and only know some data of the car, and the VIN

Scrappyjoe wrote: ↑Mon Apr 01, 2024 4:56 pm Boekel, do you what chemistry these packs are? LFP/NMC?

NMC normally, as I go for the long range versions.

Do you know how I can spot if it's LFP with the VIN number or another way?

Taking it further apart: you actually need to be on the underside! So I made a sandwich and flipped the battery, first there is a cover plate, with a 'sharpened' E16 bit I was able to remove the security / one way screws. the cover plate is also glued quite well to the modules, putting pulling force...

4 CMU's (max = wdr compatible)) each serving 24s.

easy to dismantle battery, very re-usable.

Ok some disappointment...

The modules are glued into the battery housing!

hoping for some safe way to dismount them..

(or someone that can use it as is)

(still have to dismantle the pack further)

I read here and there it would be LFP, but the numbers don't add up...I think it's normal NMC (Samsung) 12s and 8s modules, works with: https://wdrautomatisering.nl/product/cmc-max17841-gateway/ 2024-03-27 15.51.49.jpg 2024-03-27 15.51.55.jpg 2024-03-27 15.52.01.jpg 2024-03-27 15.52.16.jpg 2024-03-2...

They might fall off.

Ha yes, a friend of mine found out some time ago

I normally don't take the standard range packs btw.

that will be difficult, and I prefer not to take them apart. Do you know what build dates have those packs?

I'm getting more and more Model3/Y packs offered. I can get them with charge socket and complete with motor also. VIN number of donor vehicle included prices fluctuate a bit, but as a guide: 75(?) kWh long range pack plus charge port incl charge module €5000 above, plus rear motor €8000 above, plus ...

Other BMW designed packs (like the Mini) also have the CMU's not too close to the modules. very common. And yes, most have fuses on the modules. (nissan Leaf does not for example) For me it also makes more sense to have the CMU's on the modules, but for some reason they don't. active balancing is re...

Smaller now

Looks like this family:
check for the correct key (altough you can cut some tabs to make them fit)

Interesting, I might have "boat" for these. Could be the same CAN messages as another BMW ones, but not verified?

I suspect a 2-wire comms:

so:

3 small modules 4s each, 3.11 kWh
