Abstract: An energy storage apparatus 20 includes: energy storage devices B1 to B4; a cutoff switch 40 that cuts off current of the energy storage device; a parallel circuit 70 including a rectifier element 75 in which a discharge direction is set to a forward direction, the parallel circuit 70 being connected in parallel to the cutoff switch 40; a first current sensor 50 that measures the current of the energy storage devices B1 to B4; a discharge circuit 90 that discharges an inspection current to the first current sensor 50 through a discharge path including the parallel circuit 70 using the energy storage device as a power source; and a controller 80. The controller 80 determines whether the first current sensor 50 correctly measures the current based on a measurement value of the inspection current Ib.
