Abstract
A method of charging a battery and a battery pack utilizing the same, is disclosed. The method enhances the battery life characteristic of a battery cell by varying the charging parameters (e.g., charging voltage, charging current, rate of charge, relative state of charge, and battery capacity) based a temperature of or around the battery cell is in a normal, extended, or abnormal temperature range when the battery cell is fully charged. The charging method includes determining whether a battery cell is being charged, and if the battery cell is being charged, determining whether the battery cell is fully charged; if the battery cell is fully charged, determining whether a temperature of or around the battery cell is in a normal range or in an extended range; and if the temperature is in the normal range, selecting a first charging parameter set, and if the temperature is in the extended range, selecting a charging condition of the battery cell as a second set value.
