A lithium polymer battery state of battery charge (SOC) is a determinant for monitoring charging and discharging the battery factor. If we can control the operating status of the battery to prevent overload and underload, increasing the useful life of the lithium polymer battery. Based on the fact that the SOC level cannot be determined in form direct as it depends on the internal parameters of the battery, the temperature, and the level of aging. It is necessary to develop a technique to perform measurements in real-time voltage, current, and temperature of the battery. It determines a dynamic model of the battery and estimates the state of charge SOC from the robust extended Kalman filter.
