A method of determining the state of charge (SOC) of a battery. The method includes receiving battery parameters for a battery, and based on the received battery parameters for the battery, determining an estimated voltage of the battery and determining an estimated SOC of the battery. The method also includes receiving a measured voltage of the battery, determining a voltage error value based on the measured voltage of the battery and the estimated voltage of the battery, correcting, using the voltage error, the estimated SOC to determine a corrected SOC for the battery, and operating the battery based on the corrected SOC.
