Hi, Tom,
My board using bq40z60 (designed based on EVM) will stop charging the battery before battery is full. I tested 3 times, all of them were stopped at around 3.9V or 4.0V. When the charging stopped, I captured the registers image as below:
- Battery status changed from 0x4080 to 0x8080. It means "OCA" -Over Current Alarm is set. Why?
- Operation Status A register changed from 0x0197 to 0x4993. "XCHG" =1, charge disabled; "SS"=1:Safety Mode actived. Why?
- Charging status register changed from 0x0008 to 0x0308. "CVR" =1, "CCR" =1. Why?
BTW, I am using 3S1P LiPo 5000mAH battery pack. I changed its cell capacity from defaulted 4400mAH to 5000mAH.
Could you please help to find out what the problem it may be? Thanks,
L.
