Abstract
A method of calculating the SOC of a battery in real time includes a battery parameter measurement operation for measuring current, voltage, temperature, and degradation degree of battery, and a real-time SOC calculation operation for calculating the SOC of the battery in real time based on the measured battery parameter. The real-time SOC calculation operation calculates the SOC of the battery in real time using an Extended Kalman Filter.
