A power storage system according to the present invention regulates DC power from a DC power supply into prescribed voltage and current using a DC-DC converter unit for storage in a power storage unit. The power storage system includes primary side current and voltage detecting units, a primary side switch unit, and a primary side filter unit on the DC power supply side (primary side) of the DC-DC converter, and a secondary side filter unit, a secondary side switch unit, secondary side voltage and current detecting units on the power storage unit side (secondary side) of the DC-DC converter. The on/off states of the primary side switch unit, the DC-DC converter unit, and the secondary side switch unit are controlled by a system control unit having an externally applied operation command and signals obtained from elements such as the primary side current and the primary side voltage detecting units.
