description | Provided is a battery control device that can achieve an improvement in computation accuracy of an internal resistance and an SOH. The battery control device includes an SOH computation unit which calculates an internal resistance value of a battery, and controls the battery on the basis of the internal resistance value calculated by the SOH computation unit. Then, an internal resistance computing determination unit calculates an index indicating a polarization voltage of the battery, and determines whether the index is equal to or more than a determination threshold. When the internal resistance computing determination unit determines that the index is equal to or more than the determination threshold, the battery is controlled on the basis of the internal resistance value calculated when the index is less than a determination threshold before the determination. |
