Abstract
A charging current setting method includes an upper limit temperature recognition step which recognizes an upper limit temperature of the secondary battery (), an actual temperature recognition step which recognizes an actual temperature of the secondary battery (), a maximum power recognition step which recognizes an maximum power according to a heat quantity which the secondary battery () allows during a charge period based on a difference between the upper limit temperature and the actual temperature, a thermal resistance of the secondary battery (), and a length of a predetermined period and the charge period, and a current setting step which sets a charge current to be an upper limit value or less by recognizing the upper limit value of the charge current of the secondary battery () based on an endothermic and exothermic characteristics map of the secondary battery () with respect to current and the maximum power.
