Battery control device

A battery control device comprising:

• an acquisition portion that acquires a measured value of the state of a battery every predetermined period;
• and
• a determination processing portion that determines whether the measured value is within a given range to determine whether the state of the battery is normal or abnormal based on the determination result,
• wherein the determination processing portion determines that the state of the battery is abnormal when the number of times the measured value is determined to be out of the given range reaches a predetermined threshold until the acquisition portion acquires the measured value a predetermined standard number of times,
• wherein if the number of times the measured value is determined to be out of the given range is less than the threshold when the acquisition portion acquires the measured value the standard number of times, the determination processing portion performs the determination whether the state of the battery is normal or abnormal for an extended period, until the number of times the measured value is determined to be out of the range reaches the threshold, or until the measured value is determined to be within the range, based on the measured value acquired by the acquisition portion more than the standard number of times.
