摘要： Measuring device measures a terminal voltage of the battery in an open circuit state in a specific cycle after completion of a charge or discharge of the battery and collecting device collects the measured terminal voltage. Computing device computes a voltage value, to which a power approximation expression asymptotically approaches, as an assumed open circuit voltage of each time period from the collected terminal voltage, wherein the power approximation expression has an exponent of −0.5 or about −0.5 and is determined on the basis of the terminal voltage of each time period of a plurality of predetermined time periods. The assumed open circuit voltage of a time period, in which its difference from the assumed open circuit voltage of a neighboring time period becomes minimum, is estimated as an open circuit voltage.

摘要： A method and an apparatus for computing a charging state of a battery without being affected by an influence of polarization are provided. First computing means computes a voltage-current characteristic including the influence of the polarization during an decrease of a discharge current of the battery on the basis of a terminal voltage and discharge current measured while the battery carries out a constant load discharge with a current value large enough to cancel a charge-side polarization arisen in the battery at least just before the discharge. A second computing means shifts the voltage-current characteristic to a specific extent in the direction of a voltage coordinate axis. A residual voltage drop value in advance stored by storing means is added to a present estimated voltage value estimated by estimating means on the basis of the shifted voltage-current characteristic, thereby a present open circuit voltage of the battery is computed.
