Abstract

To provide a power storage system wherein the activation, operation and stoppage, which are important and essential during the practice of the power storage system, can be performed with reliability and wherein any kinds of extraordinary states can be appropriately dealt with. A power storage system wherein a DC / DC converter part adjusts a DC power from a DC power supply to a predetermined voltage and a predetermined current, which are stored in a power storage part. The power storage system comprises, on the DC power supply source side of the DC / DC converter part (the primary side), a primary side current detecting part, a primary side voltage detecting part, a primary side switch part and a primary side filter part and also comprises, on the power storage part side of the DC / DC converter part (the secondary side), a secondary side filter part, a secondary side switch part, a secondary side voltage detecting part and a secondary side current detecting part. A system control part, which receives an externally given operation command and also receives signals from parts such as the primary side current detecting part and primary side voltage detecting part, performs on / off controls of at least the primary side switch part, DC / DC converter part and secondary side switch part.

Description

technical field

[0001] The present invention relates to a power storage system that stores DC power and charges and discharges it, and can be used, for example, in trains and the like. Background technique

[0002] In recent years, it is known that a power storage system using a power storage device such as a secondary battery or an electric double-layer capacitor is combined with a drive control inverter mounted on a train and a power supply device installed in a ground substation, etc., to convert the vehicle The surplus regenerative power generated during braking is stored in the power storage device, and the stored power is used when the vehicle accelerates or the line voltage drops, so that the kinetic energy of the vehicle can be effectively used (for example, refer to Patent Document 1 and Patent Document 2)
