Other Parts Discussed in Thread: BQSTUDIO, , GPCRB, BQ27Z746, BQ27Z561-R2
Tool/software:
Hi,
I have completed learning cycle using bqStudio on BQ27427EVM.
Then, I tried to verify SoC value during discharging at low temperature condition like 0degC.
Test condition is as below.
Temperature : 0degC
Discharge rate : 0.5C
Design capacity : 505mAh
The test results were like attached photos.
SoC value was not gradually changed, like SoC value 99% to 0% changed suddenly or SoC value went down but recovered to 99% repeatedly.
SoC value during discharging at nominal temperature seems to be normal, but at low temperature condition, SoC value seems to be improperly.
Please kindly let me have advice what kind of setting or process needs to be done for such low temperature condition usage.
As far as I know, GPCRB process cannot be applied for such ROM based gauge like BQ27427.
