A power storage system capable of surely carrying out activation, operation, and stopping that are crucial and necessary in the use of the power storage system and appropriately addressing various kinds of abnormalities is provided. The power storage system 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 a primary side current detecting unit, a primary side voltage detecting unit, 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, a secondary side voltage detecting unit, and a secondary side current detecting unit on the power storage unit side (secondary side) of the DC-DC converter, and the on/off states of at least the primary side switch unit, the DC-DC converter unit, and the secondary side switch unit are controlled by a system control unit provided with an externally applied operation command and signals obtained from elements such as the primary side current detecting unit and the primary side voltage detecting unit. |
