1. An electric power control system comprising:

  • an electrical equipment configured to be supplied with electric power from one of an electric power supply system and a secondary battery;

    an electric power supplying part including the electric power supply system and the secondary battery;

    a plurality of electric devices that receive electric power from the electric power supplying part, the electrical equipment serving as one of the electric devices;

    an environment sensor that detects physical amounts representing a condition of an environment of the electric power control system and outputs detection data; and

    an electric power control device that controls electric power supplied to the electric devices,wherein the electrical equipment includesa switch circuit that switches a power supply source for supplying electric power to the electrical equipment between the electric power supply system and the secondary battery; and

    a module includinga controller to control the switch circuit to selectively connect the electrical equipment to one of the electric power supply system and the secondary battery according to a control signal supplied from an external device; and

    an electric power sensor that detects electric power and outputs detection data,wherein the electric power control device includes a computer that executes a program to perform an electric power controlling process including;

    collecting the detection data from the electric power sensor and the environment sensor and storing the collected detection data in a detection data storing part;

    storing control condition data in an electric power condition data storing part, the control condition data including information regarding a contract amount of electric power previously set and information regarding an accumulated amount of power consumption;

    storing control device data in a control target device data storing part, the control device data including device identification information for identifying each of the electric devices and priority order identification information for identifying a priority order given to each of the electric devices;

    acquiring a first result from determining which one of the electric power control system and the secondary battery is to supply electric power to the electric devices on an individual device basis based on information including the detection data, the control condition data and the control device data, and also acquiring a second result from determining an amount of electric power to be supplied to the electric devices on an individual device basis or determining whether to stop supplying electric power to the electric devices on an individual device basis; and

    sending an instruction to the module to control the switch circuit in accordance with the first result and the second result, andwherein the control condition data stored in the electric power condition data storing part includes a total amount of power consumption determined by a user, information regarding a battery remaining amount value, information regarding a planned power outage, information regarding a demand response, and information regarding an interruption of electric power supply from the electric power supply system.
