POWER SUPPLY CONTROL DEVICE

摘要

A power supply control device that controls power supply from a power source device to a plurality of loads includes a circuit that parallely connects the plurality of loads to the power source device. The circuit is connected to a plurality of switches that switch between a connection and a shut off between the power source device and the plurality of loads. The power supply control device further includes a priority setting unit that assigns priorities to the plurality of loads, a power detection unit that detects a change in a total power consumption by the loads that are connected to the power source device, a load identifying unit that repeatedly performs a load identifying process, and a changeover control unit that controls a changeover of the switch corresponding to the load that is identified as the connection target and to connect the power source device to the identified load.

1. A power supply control device that controls power supply from a power source device to a plurality of loads comprising:
a circuit that parallely connects the plurality of loads to the power source device; a plurality of switches connected to the circuit that switch between a connection and a shut off between the power source device and the plurality of loads; a priority setting unit that assigns priorities to the plurality of loads; a power detection unit that detects a change in a total power consumption by loads that are connected to the power source device among the plurality of loads; a load identifying unit that repeatedly performs a load identifying process on all loads shut off from the power source device among the plurality of loads, based on a detection result of the power detection unit, the load identifying process selecting one load according to the priority when the total power consumption by the loads connected to the power source device has decreased, identifying the selected load as a connection target when a total power consumption by the selected load, a load that is already identified as a connection target and the loads that are connected to the power source device is not greater than an upper output limit that is set according to an output capacity of the power source device, and does not identify the selected load as the connection target when the total power consumption by the selected load, the load that is already identified as the connection target and the loads that are connected to the power source device is greater than the upper output limit; and a changeover control unit that controls a changeover of the switch corresponding to the load that is identified as the connection target by the load identifying unit and to connect the power source device to the load that is identified as the connection target.
