Hi
The customer design with BQ27742-G1, The golden file is successful.
when use 0.1C for discharge, and SOC also decreases to 0% smoothly. But when use smaller current to discharge in pulse load mode, the problem as below:
1. SOC drop from 5% to 0%
2. RSOC to 0% early to 3V (set to 2.8 V)
3. It is normal in the first cycle, and often occurs in the second cycle
Attached the gg file.
Default is golden setting gg file.
Sample C the jump occur gg file.
S default and Sample C gg(20230206).gg.csv
Plus discharge as below:
Why the SOC will drop in plus discharge mode?
How to improve it
Thanks
