Specs. Samsung 49,5Ah prismatic NMC from Ford Kuga PHEV 12s1p module.

[MrSparkle]

I have been trying to find specifications / data sheet with all the charge/discharge curves, voltage-ranges, C-rates, life-cycles, etc, for Samsung cells coming from a 12s1p Ford Kuga PHEV module. (Unknown year.) (The cells are laminated with black plastic.) Tried to search internet and this forum. I am a "member of Flintstone family", so I don't have smartphone or alike. Have no idea how or where to search for specs via the QR code.

Any and all help on how, where, etc, are highly appreciated.

Info on the sticker of the module:

Battery cellmodule 12s1p
Part number: 1000134700
Module number: MP0021NS001A
Cell type: 49.5Ah C-sample
Serial number: 2011170480
Made in Hungary


Info on the cells:

Laser engraved number: 360420A0168880KPPS1B
Printed sticker with x2 QR: CS0495RT006A Energy: 178 Wh

I have a 23.3kWh 14S NMC battery built from Panasonic cells from Ford Energi PHEV.

For NMC per cell:

4.20V = 100% SoC
3.92V = 75-80% SoC (this varies a little depending on the "blend" of NMC)
3.50V = 20% SoC
3.00V = 0% SoC

Thanks sunny!

this varies a little depending on the "blend" of NMC

Yeah, hard to know if it is a regular 33%-33%-33% or some other.

I did find specs earlier for Samsung 94Ah in resources:
Samsung SDI data sheets.
But didn´t want to jump to conclusions that specs are same (except for Ah). "Assumption is mother of many f***ups."

Or do you think mine 49.5Ah and the 94Ah in the resources have same (/almost same) chemistries so I can use the 94Ah as guide line?

Anyway. So far, most researches online points to, cycling from 4.15V down to 3.20V should be quite normal working range.

I do plan to find a way to do a proper capacity test on these. But do not have solid equipment for that yet, to generate those fancy grafana charge/discharge curves with the knees and all the other "bells and whistles".

For a normal working range, I use 3.92-3.50. If I anticipate needing more capacity, I'll go up to 4.05 or 4.15, and frankly, while I prefer 3.20 as an "emergency" lower limit, I'll go down to 3.00 if it comes down to it. My C rates are rarely over 0.25C, and my cells are rated for 6C continuous.

My choices also hinge heavily on my own full 3.00-4.20V range testing. I tested each individual cell (294) for capacity and have tested the entire battery on multiple occasions confirming capacity and SoC to voltage relationships.

Blatherings about my battery. Also have some discharge tests:

It has been years in the making, but I finally have the NMC battery poised for deployment... (okay, only half, but still).

Summary:
7X Ford Fusion/C-Max Energi PHEV batteries, 7.6kWh rated per pack.
Each battery: 84S 25Ah 3.7V NMC cells. Four subpacks of 21S in series
Packs have tested 19-24Ah
28 total subpacks (modules), packs of 4 pictured below:



Config:
21S modules disassembled, cells flipped to the same polarity and reassembled into a 21P module.
Cells connected with custom Aluminum bus bars (.25" x 1"), 21 holes each, 2 per module, 28 bus bars, 588 holes...

Hi MrSparkle, I am interested in this topic. I haven't found the specifications like you have. I'm interested in converting a car to electric, but I need to know the discharge rate of the battery packs. I also need to know about the fuses, contactors, etc. My idea is to put 3 battery packs in parallel. Have you been able to find any information? Have you bought the complete pack? Thanks in advance.

Hello Nacho!
Unfortunately I have not found data sheet for these specific sells. I have already bought one 12s1p module, dismantled it and rebuilt to 10s1p battery for my DIY e-bike. My system C rates are very low. 0,15C charging and 0,15C constant discharging (0,5 surge). To my understanding, that is way below almost any cell. These Samsung cells most probably are manufactured to handle significantly higher C rates, I believe.

Thanks, I will continue digging.

Thanks, I will continue digging.

There is a website with a "virtual cell representation". Slightly different model number, but most probably, overall same cell with same characteristics. Just a hunch though.
