Zusammenfassung:	PROBLEM TO BE SOLVED: To perform charging efficiently even if the values of currents flowing through a plurality of battery modules connected in parallel are different.SOLUTION: A charging controller 20 for controlling the charging currents supplied to a plurality of battery modules 12 connected in parallel compares the maximum current value, selected from current values detected by current sensors 18 provided, respective, for a plurality of battery modules 12, as a maximum current value supplied to a secondary battery 16, with a predetermined reference current value, and controls the charging current supplied to the plurality of battery modules 12 based on the comparison results.
