Method of quick charging lithium-based secondary battery and electronic device using same
InactiveUS20100156356A1Prevent overchargingFast chargingBatteries circuit arrangementsCell seperators/membranes/diaphragms/spacersElectrical batteryTerminal voltage
A charging current is maintained at a predetermined constant quick charging current (S1) and a full charge determination is made at a point in time (S7) when the terminal voltage (V1) (S6) reaches the charge end voltage Vf′. The charge end voltage Vf′ is taken as a voltage (S5) obtained by adding a voltage drop amount VD (S4) that is obtained by multiplying an internal resistance value (S3) estimated from the temperature T (S2) of a secondary battery by a quick charging current value to a predetermined initial charge end voltage Vf. Therefore, a constant high current can be supplied from the beginning to the end and quick charging can be performed up to a full charge, while preventing overcharge, in place of the conventional CC-CV charging.
