초록

A secondary battery is charged with a constant voltage, while a charging current generated by the application of the constant voltage is monitored. After the charging current becomes smaller than a predetermined current value, an open circuit voltage of the secondary battery is sampled at a predetermined interval while substantially stopping charging. Charging is completed, when either a voltage difference between a terminal voltage of the secondary battery and the sampled open circuit voltage becomes smaller than a predetermined voltage difference value...

청구항

A method of charging a secondary battery, comprising the steps of: charging the secondary battery with a constant voltage to generate a charging current, the charging current decreasing as a function of time to a stable, low level of charging; maintaining charging of the secondary battery until detecting a first occurrence when the charging current becomes smaller than a predetermined current value; substantially reducing charging of the secondary battery on a first occasion in response to detecting the first occurrence when the charging current becomes ...
