Abstract
A power storage system includes: a power generation element that performs environmental power generation; a storage battery that is supplied with power generated by the power generation element; a DC/DC converter that converts an output voltage from the power generation element into a predetermined voltage; a first switch unit that switches whether directly supply the output voltage from the power generation element to the storage battery or to supply thereto via the DC/DC converter; and a first changeover unit that compares a voltage of the storage battery with a first threshold voltage, and controls the first switch unit according to a comparison result, in a case where a voltage of the voltage or higher of the storage battery bringing the DC/DC converter into a main boost mode is the first threshold voltage.
