A charging system (10) is constituted by including a battery assembly (14) constituted by a plurality of storage batteries (12), a switching unit (16), a charging control unit (18), and a battery management unit (20). The battery management unit (20) is equipped with: a voltage acquiring section (22) for acquiring a terminal-to-terminal voltage (VB) of the battery assembly (14) on which constant current charging is being performed under the control of the charging control unit (18); and a transmission processing section (24) for, when the acquired terminal-to-terminal voltage (VB) of the battery assembly (14) reaches a predetermined threshold switching voltage (V0), transmitting a switching command for prompting the charging control unit (18) to switch from constant current charging to constant voltage charging.
