hi bud, great write up, how's it running now? I bought a 2018 BMW 530e battery pack for an EV Conversion and am absolutely lost where to even begin with Simp BMS, I have download the so called "manual" and haven't got a clue how to wire it, do you think you could help me?

SIMPbms Teensy arduino breakout board + BMWi3 firmware will work with BMW i3 BMW i8 and e-MINI,
so I think you're trying to use the wrong battery.
It is not working with BMW hybrid battery packs, at least we never tested it.

with the right BMW EV second-live battery,
easiest way of connecting is to recycle the original bms cable with its 8 black connectors, and the blue (number 9) connector,
if based in Europe, one can order at Hubauer.de "HERE" at just ~€24, original and tested

with kind regards

Carel, Darkwing, Ive got a i3 battery pack now with 6 cells, plus one spare.
Looking at the output of SimpBMS the single unit believes it is module 2.
I fear that each pack is programme with its module ID and that I may not be able to integrate this "spare" module into the spare slots in the pack
Is this the case?

Hello mr/mrs Bashers
did you check the other 5 CSC's if there's a conflict?? ie you have 2x ID2??
Maybe you are lucky, and there's no duplicate on the can-bus.


best regards,
Carel
