Abstract

See full text

Method and charging device for charging a battery comprising the steps of introducing a charging current into the battery using a charging device, monitoring a cell temperature of the battery by means of a sensing device, detecting that the cell temperature has reached a given temperature range by comparing the temperature detected to a predefined cell temperature for the battery in a processing unit and instructing a control unit to successively reduce the charging current until the cell temperature reaches a predefined lower limit of the given temperature range. Thereafter, the charging current is maintained at the level at which the predefined lower cell temperature level has been reached. Alternatively, the charging device may use a predefined optimum cell temperature interval to which the current temperature of the cell battery is regulated by regulated the charging current.
