Part Number:BQ78350-R1
Dear TI Experts,
For CEDV gauge, such as BQ78350, we need to set Fixed EDV0, Fixed EDV1,Fixed EDV2 before performing a learning cycle then upload data to GPCCEDV tool.
However, I'm not sure how to set these 3 paremeters , below are 2 methods I heared, could you kindly help to suggest which one is the right choice? Is there another better way to setting Fixed EDVx ? Thanks a lot.
1) Discharge from full to empty with 0.2C, 0.5C, 1C, 5A in room temperature, and calculate the EDVs with 7%, 3%, 0% of RSOC for each discharge rate, then avarage the result in 4 different discharge rate for EVD0.EDV1,EDV2; Perform 3 cells with above cycle, and do the avarage to decide the final Fixed EDV0, Fixed EDV1, Fixed EDV2
2) Discharge from full to empty with actual load with typical user case in actual temperature the pack will be put , and calculate the EDV2,1,0 with 7%, 3%, 0% of RSOC ; Perform 3 cells with above cycle, and do the avarage to decide the final Fixed EDV0, Fixed EDV1, Fixed EDV2
