Other Parts Discussed in Thread: GPCRB, GPCCHEM
Dear colleague,
Our customer is using BQ27520-G4 in their design, but they encounter that when temp is below 0 ℃, the battery capacity jumps to 0.
Now we have some concerns need your confirm:
1. In-room temperature, the terminal voltage is 3.4V, in temperature <0 ℃, the customer want to set the terminal voltage to 2.8V. And in temperature <0 ℃ when they source 1A from the battery, the battery voltage will drop to 2.86V. So how to realize different terminal voltage at different temperatures?
2. After using GPCRB, the Qmax in GPCRB report should be larger than Qmax in room temperature? Or not?
3. In-room temperature gg file: Design capacity is 5000mAh, but in GPCRB output gg_out file: Design capacity is 1000mAh. This is right?
4.The Ra in GPCRB report and gg_out are different, Which one should we use?
Thanks a lot!\
Best Regards,
Rock Su
