<p>PROBLEM TO BE SOLVED: To provide a discharge capacity control method of a battery and a device of the same capable of holding engine startability in a target standing period by acquiring discharge capacity of a battery with high accuracy by reflecting change of internal resistance.SOLUTION: A voltage OCV and internal resistance Rin of a battery 10 is measured by a battery sensor 110 (Step S1), and SOF is calculated by inputting each of measured values of the voltage OCV and the internal resistance Rin of the battery 10 from the battery sensor 110 by a power supply management control unit 120 (Step S2). Then, it is determined whether the calculated SOF is larger than a threshold value SOFlimit or not (Step S3), and when the SOF is determined to have reached the threshold value SOFlimit, a signal is outputted to a switch 130 and a dark current is cut off.</p> |
