SYSTEM CONTROLLING BASE STATION DEVICE CONNECTED TO POWER GRID, BASE STATION DEVICE, BASE STATION DEVICE CONTROL DEVICE, AND CHARGING CONTROL METHOD THEREFOR

摘要

A base station device that: is connected to a power grid base station device having power supplied thereto from a power plant; has a storage battery also installed; and, once a determination is made that the power supply status of the power grid is unstable, stops charging the storage cell, reduces the charging speed, or reduces the load on a load device, and avoids power grid power outages. In addition, an inter-base station device control device is capable of avoiding power grid power outages and avoiding operation stoppages, by charging a storage cell connected to a base station device requiring more operation, by controlling a plurality of base station devices connected to the power grid.
