    摘要: The present invention provides a method for detecting a fully charged condition of a secondary battery by which the fully charged condition of a secondary battery can be detected accurately and deterioration in battery characteristic due to overcharging can be restrained irrespective of the charging mode and the surroundings, without the need for a special battery structure. In the method, pulse vibrations generated inside a secondary battery being charged are detected, and when the obtained characteristic value of the pulse vibrations, for example, incidence of generation of the vibrations reaches a predetermined value, the secondary battery is determined to be in fully charged condition.

    摘要: A method of charging a battery and a battery pack utilizing the same, is described. 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, incrementing a first count and selecting a first charging parameter set if the first count is greater than a first reference count, and if the temperature is in the extended range, incrementing a second count and selecting a charging parameter set if the second count is greater than a second reference count.
