Good day all.
I am soon to be starting a new project, and I am looking for some help and advice before I get in to deep.
I have a 36v e-bike, and the battery pack has a ApolloGroup LT-013SF BMS, and this is based on the 02Micro OZ890 chip.
The 02Micro OZ890 chip has an i2c interface where the parameters of the BMS can be viewed or adjusted.
I just want to be able to monitor and view each of the cells voltages in real time, via an LCD or OLED display.
But at this point in time I just wish to be able to pull each of the cells data, and push the data out over serial, so that I can just view the data via windows serial console monitor.
From reading the 02Micro OZ890 datasheet all the real time data is held in the Operation Registers Map, (Page 65 of Datasheet).
Now this is where I am stuck, I don't yet understand how to use the details of the Operation Registers Map, so that I can call the needed data for use with each of the battery cells.
If someone has the free time, can someone please try and explain it to me?
Thanks for your time.
Best Regards.
