Pack Quality Requirement for safety and quality epidemic issue.
1-1 The battery pack’s consumption current.
- Sleep Mode : Under 250uA.
- Shut Down Mode : Under 10uA / Under 3.0V.
Under 1uA / Under 2.5V.
1-2 SOC 0%
- Cell voltage in SOC 0% of Pack should be Min. 3.0V.
(Discharging Cut-off Voltage)
1-3 Operating Charging Voltage of a cell.
- Normal operating voltage of a cell is 4.20V
- Max operating voltage of a cell is 4.25V.
1-4. No continuous charge
- Charge cut-off condition : Cut-off Current over than 1/20C
- (Charging method:CC-CV)
- Initial recharging condition : Remaining Capacity under than 90% or voltage
under than 4.10V
1-5. Pre-charging function
- Pre-charge function should be implemented to prevent abnormal high rate
charging after deep discharge.
- Pre-charging condition Operation : Under 3.0V
Charging current : Under 150mA/Cell.(Continuous)
Pre-charge stop (Normal Charge Start) : All cells reach 3.0V
1-6. Cell voltage monitoring system.
- The system (Charger or Pack) should equip a device to monitor each Cell
voltage and to stop charging if a cell imbalance happened.
1-7 The battery pack should have warning system for over temperature, over voltage,
over current, and unexpected events would be harm to system. If battery faces
harsh condition such as over temperature, Battery pack should control FET-off
directly.
