  • Patent number: 9859750
    Abstract: A power distribution control apparatus includes a power source switcher that switches a power source for supplying electric power to a plurality of load groups between a commercial power source and a battery, control circuitry that controls the power source switcher and a plurality of switches provided in power supply paths between the power source switcher and each of the load groups, and a memory that stores positions of the plurality of switches in the order of priority. When the power source switcher switches to the commercial power source and a power saving time zone in which commercial power consumption is to be reduced is reached, the control circuitry controls the switches to be in a non-conducting state, switches the power source from the commercial power source to the battery using the power source switcher, and sequentially controls the switches in a conducting state in the order of priority.

  • Patent number: 9819222
    Abstract: A power control apparatus includes the following elements. A measure measures a value of a current to be supplied from a power supply source to a load set. A switch is disposed on a power supply path from power supply source to a load set. A setter sets a first maximum current value in the case of a normal state in which the load set receives power from a main power supply source and sets a second maximum current value when the load set receives power from the sub power supply source. Control circuitry turns OFF the switch when the value of the measured current exceeds the first maximum current value in the case of the normal state and turns OFF the switch when the load set receives power from the sub power supply source and the value of the measured current exceeds the second maximum current value.
