1. A battery capacity detection system comprising:

  • a temperature sensor sensing a temperature of a battery;

    a full-charge voltage calculation processing section for calculating a voltage of the battery in a fully charged state by using the temperature of the battery sensed by the temperature sensor; and

    an SOC calculation section for calculating an SOC of the battery by using the voltage of the battery in the full charge state calculated by using the temperature by the full-charge voltage calculation section.
