48v or 12v? Help Me Get This Battery Working!

Here's all of the information I have on it.
I believe its this battery:

Nice break down. Thanks for sharing.

[@AdamBoguski]

Thanks Ben. What are the dimentions of the 12s battery alone? The Sigeneer inverter designed for 2 Tesla module voltages would be a perfect match here. I like your set up with 2 pole QO load center used as a DC combiner.

[@JohnSmith-qd8po]

It's a multifunction module with lots of inputs and outputs. You could try tracking down the wiring diagram of the vehicle that the module is used in. That might give you some insight as to where to apply your voltages or jumpers. That is an impressive rating of 3Kw for the DC to DC converter though.

[@DavidSmith-dm8ew]

If the 12v inverter hooks to the rest of the car wiring system and needs the key or something in the car's computer in order to turn on it will probably be a total loss.

Isn't 41.9v in a discharged state? I was under the impression that a charged 48v should be show in 52v neighborhood.

[@melovescotch]

for normal Li 12s that voltage would be low state of charge.

[@jfbeam]

@@melovescotch 3.5v/cell isn't that low. Without knowing the exact specs for those cells, it's hard to say what the SoC is. A few charge/discharge cycles will tell.

CAN bus is Simple. Find the pin outs for the DC to DC converter and the should be a CAN Hi and a CAN Low. Well worth trying to get it to work. What’s the brand, model # etc. so we can look it up?

[@benssolarandbattery]

Thanks Paul, I left all of the part numbers along with a link to what I think it came out of in the description. Once I find CAN hi and low, what do I do with them? From my brief research about it, it sounds like CAN as a whole is similar, but there are different "languages" so without knowing those, it's difficult to figure it out.

[@jfbeam]

Finding the CAN lines is about 1% of the equation. If no one has publicly documented how to talk to it, it will be impossible to use. (and without the car that uses it, there's no bus activity to watch and figure out.)

[@fisherus]

I think, like most hybrid vehicles that run their interior electrical systems from the power cell, the vehicles computer controls the transformer. Too bad the battery isn't a 13S and integratable into your battery bank system, Ben. I imagine that's what you are thinking also?

[@offgridwanabe]

Really nice junk the cells are the only thing of salvage unless you can program can bus. Oh nice fuse too that dc to dc converter/bms must be working as it was shut down at first with no voltage. be interesting to apply 12 volts to it to see if the 48 volt comes alive. Good luck.

[@BenMitro]

I don't think the right question is how do you make it work, the real question for 480Wh should you bother? Now that DC-DC might be useful somewhere, sometime, but like another commenter points out - a lot of work for something that could be dead anyway.
