I am using BQ24032A& BQ27500-V130 at our product, BQ24032 for charge and BQ27500 for faul gauge . Now there are some questions:
1. I need to make our golden pack , should I do it on our user board or we still can use EV2300 board?
2. If we just can use our board, then we must disconnect our load when we should let the battery relax?
3. I use the battery to power the used board (or EV2300) during make golden pack, if we should disconnect BQ27500 from battery when the battery shoule be relax?
4. If 50mAH capacity of battery should be kept in reserve, what should I do? step 2D can set this, should we do this bofore to make the golden pack or after that?
5. During the process of making our golden pack, there are some messages and we cannot finished it. the message are
Sorry, can't continue. Fully Charged (FC) bit is not set. Please insure charge termination occured normally. (step3 of 5A, In fact, I really terminated the charging normally according STAT1&STAT2 of BQ24032A and I read FC=1 from the RAM of BQ27500 via EVSW.
Dataflash. GasGauging. State.UpdateStatus does NOT =2 .Impedance track learning cycle was not completed correctly. Verify procedure and repeat.(the last step of 5A, I really discharged it to empty and relax 5 hours, but maybe the time is longer than 5hours)
6. If BQ27500 was power off, then the data stored at the RAM such as FC flag will be lost?
7. If our PCB was relayout, then the golden pack should be made again or just need to calibrate the board?
thanks
