POWER-SUPPLY CONTROL SYSTEM, POWER-SUPPLY CONTROL METHOD, AND IMAGE FORMING APPARATUS

摘要

A power-supply control system includes a plurality of apparatuses connected to each other. Each apparatus includes a battery configured to supply power in a power saving mode where power consumption is lower than in a normal mode; a detecting unit configured to detect an output voltage of the battery; a transmitting unit configured to transmit a power supply request when the output voltage is determined to be lower than a predetermined value; a receiving unit configured to receive a request from another apparatus; a determining unit configured to determine whether the battery is available for the another apparatus in response to the request; and a control unit configured to control power supply from the battery. The control unit transmits a notification of power supply start to the another apparatus and causes the battery to supply power to the another apparatus when the battery is available for the another apparatus.
