  • Information processing apparatus and battery degradation detection method
    Patent number: 8483983
    Abstract: According to one embodiment, an information processing apparatus is configured to be powered by a battery. The apparatus includes a charging circuit, a charging current measuring module, a charging time measuring module, and a calculation module. The charging circuit charges the battery by using power from an external power supply. The charging current measuring module measures a charging current supplied to the battery from the charging circuit. The charging time measuring module measures a time during which the battery is charged by the charging current. The calculation module calculates a charging capacity from the measured charging current and the measured charging time, and compares an accumulated charging capacity, which is obtained by cumulatively adding the calculated charging capacity to a previously calculated charging capacity, with a reference value, in order to detect degradation of the battery.
