1. A charging system which charges a power storage device formed by connecting a plurality of power storage elements with electricity, comprising:
an alternating current (AC) power source;
a plurality of rectifying units which are connected to a plurality of modules formed by dividing the power storage device into the plurality of modules and supply direct current (DC) electric power obtained by rectifying AC electric power supplied from the AC power source to the plurality of modules;
a plurality of opening/closing units which switch between connection and disconnection between the AC power source and each of the plurality of modules; and
a control device which controls connection and disconnection of the plurality of opening/closing units in accordance with a state quantity of at least one of an output voltage of the AC power source and an input voltage of the rectifying units or a state quantity associated with at least one of the output voltage and the input voltage,
wherein the control device sets an upper limit number of the opening/closing units to be connected at the same time among the plurality of opening/closing units in accordance with the state quantity and sequentially switches and selects the upper limit number of the opening/closing units to be connected from among the plurality of opening/closing units.
