Reading and writing BMS on NFCP3628B battery
Posted: Sat Jul 08, 2023 3:41 pm
Hello,
yes I'm new and yes I mostly did register to find a solution to my problem.
I did read that the SNSC 2.3 1kW battery can not be flashed with an working firmware to remove the "40W" cutout limit.
What I did not find was: Why can it not be flashed? Is there no working BIN file without the limit?
That would be fine for me as long as I can read and write the BMS firmware.
First of all: I did not steal any of these batteries.
But most important I do have 2 NFCP3628B batteries with the HD3629-BMS-A02 board. One of them has a pre production firmware on it, that does not yet have the 40W cutout. So it works totally fine.
I also got an ST Link programmer, but can not get it to read the batterys BMS firmware (but also never used it before, so that might be user error?)
Can someone help me what settings I should use in the STM32 Link Utility and tell me if I'm just connecting the pins wrong?
Or is the BMS really so locked that I can not even connect to it?
So I mostly just want to read the BMS firmware of the "good" battery and write it to the "bad" one.
Thanks very much :)
