STORAGE BATTERY MANAGEMENT DEVICE

摘要

When charging a storage battery (70), a charging management unit (845) starts charging with fixed current charging and switches from fixed current charging to fixed voltage charging when the voltage of the storage battery (70) has reached a set voltage. After charging has started, a charge ending determination unit (846) determines to end charging when a state is assumed in which the voltage of the storage battery (70) is greater than or equal to the set voltage and the charging current is less than a set current. A charging current calculation unit (842) calculates the charging voltage during set voltage charging on the basis of the amount of power to be charged and a received charging time. A charging current changing unit (843) changes the charging current to greater than or equal to the set current if the calculated charging current is less than the set current.
