Title: APPARATUS AND METHOD FOR ADJUSTING CHARGING CONDITION OF SECONDARY BATTERY
Abstract:
Disclosed are an apparatus and a method for adjusting a charging condition of a secondary battery. The apparatus for adjusting a charging condition comprises a control unit configured to: receive an input of measurement results from a current measurement unit and a temperature measurement unit for a secondary battery so as to determine a charging current value and a current temperature value; determine, by a predefined thermodynamic calculation equation, a predicted overheat amount which is required to raise the temperature of the secondary battery from the current temperature to a threshold temperature for a predetermined reference time; determine a predicted charging current which is required to generate the predicted overheat amount through charging; determine a predicted charging voltage expected when the predicted charging current flows in an equivalent circuit of the secondary battery; and when a condition of the predicted charging voltage being lower than a predetermined maximum charging voltage is satisfied, adjust the maximum charging voltage such that the maximum charging voltage is lowered to the predicted charging voltage.
