Hi guys

I checked your Slave BMS pictures, I would like to confirm some points with you:
1) Each Slave BMS manages 24 cells (2x12 cells) due to the fact that 2x MAX17845 are mounted
2) There are 24 passive balancing resistors (12 pcs per PCB side), so this seems to confirm the above hypothesis
3 ...

Thank you. I am more or less aligned with the status of Cell Monitoring ICs and their Gateway ICs.
What I would like to benchmark is not only that part of the BMS.

There are much more functionalities in a BMS:
1) Microcontrollers and Smart Regulators architecture (depends on Functional Safety ...

Thank you. Which Model Year is it? Could you please kindly share some pictures of the Master BMS, Slave BMS, and Shunt board?

Hi Everyone

I would like to support this forum, as well as learn new things about BMS latest technology on the market.
I have HW & SW development skills in general on Electronic Control Units design, and I would like to do a benchmarking analysis of the BMS products currently available on the ...

BMS seems to be built around the NXP MC33664 / MC33771, configured in 4 strings. Got a BMS-master here for reverse-engineering. Does someone have the full datasheet of these IC's available ? The basic datasheet is available at the NXP website, the full one (in which I hope to find the protocol ...
