Abstract
An apparatus and method for adjusting a charging condition of a secondary battery are provided. The apparatus includes: a controller configured to receive measurement results from a current measuring unit and a temperature measuring unit of the secondary battery, determine a charging current value and a current temperature value, determine a predicted overheat amount required to raise the temperature of the secondary battery from the current temperature to a threshold temperature for a preset reference time by using a predefined thermodynamic calculation equation, determine a predicted charging current required to generate the predicted overheat amount through charging, determine a predicted charging voltage expected when the predicted charging current flows through an equivalent circuit of the secondary battery, and when a condition of the predicted charging voltage being lower than a preset upper limit charging voltage is satisfied, adjust the upper limit charging voltage such that the upper limit charging voltage is lowered to the predicted charging voltage.
