Abstract: An electricity distribution device is connected to a system power supply and a battery pack, and includes: a primary power converter circuit converting DC electric power discharged from the battery pack into electric power supplied to the load; a first switch switching conducting and non-conducting states between the primary power converter circuit and the load; and a control circuitry controlling the first switch to switch the conducting and non-conducting states between the primary power converter circuit and the load. The primary power convertor circuit consumes DC electric power discharged from the battery pack, in a state where the first switch switches the non-conducting state between the primary power convertor circuit and the load, and a current value is acquired when discharging from the fully-charged state to an empty state. The fully-charged capacity of the battery pack is measured using the acquired current value.

Abstract: A distribution board includes: a storage battery including one or more storage batteries and electrically connected to a predetermined load; a detector which detects a power outage state in which no electric power is being supplied from a power system; a first switch between the power system and the storage battery; and a controller which controls at least the first switch. When the detector detects the power outage state, the controller turns off the first switch to electrically disconnect the storage battery and the power system, and the storage battery causes the one or more storage batteries to discharge and supplies electric power to the controller and the predetermined load.
