    摘要： The present invention provides a method for estimating a remaining capacity of a battery. The method comprises: measuring a current value, a voltage value and temperature of the battery; correcting the current value based on the voltage value; calculating a current integration value by integrating the corrected current value and calculating a current integration capacity from the calculated current integration value by reflecting a charge/discharge efficiency; determining a battery forward voltage capacity from the measured current value, voltage value and temperature, and determining whether it is necessary to correct the current integration capacity based on the forward voltage capacity; converting the current integration capacity into a remaining capacity, if it is determined that it is not necessary to correct; and correcting, if it is determined that it is necessary to correct, the current integration capacity and converting the corrected current integration capacity into a remaining capacity. With the method, SOC of the battery can be more accurately calculated.

    摘要： The present invention provides a technique for estimating a remaining capacity of a battery. In particular, the technique measures a current value, a voltage value and temperature of the battery and corrects the current value based on the voltage value. The corrected current value is then integrated and the result is used to calculate a current integration capacity by reflecting a charge/discharge efficiency accordingly. A battery forward voltage capacity is then determined from the measured current value, voltage value and temperature, and used to determine whether it is necessary to correct the current integration capacity. The current integration capacity is then converted into a remaining capacity, if it is determined that a correction is not necessary. If it is determined that a correction is necessary, the current integration capacity is corrected and then the corrected current integration capacity is converted into a remaining capacity.
