The datasheet (bq27541-v200.pdf, page 15) describes the parameter "SOH Status" at address 0x2f.
When I read this parameter, its value is always 0x00. I believe I have properly configured the gauge.
I did a test to see if the SOH would change (despite the SOH Status is not valid). See the figure below.
I configured the fuel-gauge to a battery with 2-parallel cells (design capacity = 4540mAh). I did the steps in the bqEasy wizard to create the golden image. I flashed this golden image and enabled IT (0x0021) and sealed (0x0020).
Then I removed one of the cells to halve the capacity of the battery. Using a Cadex C7400 C-Series analyzer, I cycled the battery multiple times. The charge and discharge rate is about 0.3*C = 1.3A. There is a 30 minute rest after charging and after discharging during each cycle.
I expected the SOH to decrease to about 50% after several cycles, however it remains at 100%. SOH Status is still 0x00.
Did I miss a step or mis-configure something?
