Abstract:
A power storage system 50 has a plurality of power storage blocks 60A-60C that are connected in parallel to a common line Lo through parallel lines La-Lc. Each of the power storage blocks 60A-60C is provided with a plurality of power storage elements 63 that are connected in series, and switches 65A-65C that are provided to the parallel lines La-Lc. The power storage system 50 is further provided with: inspection units 77A-77C that separate the power storage elements 63 of the power storage blocks 60A-60C from the common line Lo by switching the switches 65A-65C from on to off, and inspect minute short-circuiting in the power storage elements 63.
