Hi
The battery is a 3 series lithium battery, which is fully charged with 12.6V; over discharge current test, after OCD protection, cannot be charged.
In this state, cannot use 12.6V to charge or discharge anymore.
The reason as below:
1. The over discharge current protection recovery current is set to 10mA, it needs to be charged to recover;
2. The CHGFET bit is 0, and the charging MOS is not turned off when it is 100% full;
3. After over-current test, the total voltage of the cell is about 12.3V.
4. The charger voltage is 12.6 <12.3 + discharge MOS diode voltage drop (about 0.6V). Therefore, it cannot be charged.
2. The CHGFET bit is 0, and the charging MOS is not turned off when it is 100% full;
3. After over-current test, the total voltage of the cell is about 12.3V.
4. The charger voltage is 12.6 <12.3 + discharge MOS diode voltage drop (about 0.6V). Therefore, it cannot be charged.
The battery cannot be charged or discharged on the device.
Please give some suggestions for this phenomenon.
