PROBLEM TO BE SOLVED: To solve the following problem: in the case that timer reservation operation is implemented so that electric apparatuses are operated in a low power rate time zone, use of the electric apparatuses is impossible to make until the low power rate time zone and thus use limitation occurs in a time zone for which a user is desirous of using these apparatuses.SOLUTION: Control determination means 11 acquires information on dischargeable electric energy of an on-vehicle battery 23, determines the time for operating an electric apparatus 1 by supplying electric power from the on-vehicle battery 23 to the electric apparatus 1, and discharges electric power stored in the on-vehicle battery 23 after an electric vehicle reaches to operate the electric apparatus 1.
Abstract:
PROBLEM TO BE SOLVED: To solve the problem that since water in an electric water heater was not hot even after a least expensive electricity charge time zone elapsed, or because the water heater was still on when the user returned home and there was not enough time to fully charge the battery of an electric car, the user may not be able to use the car when the morning comes next day and he wants to use it.SOLUTION: Control determination means 11 receives information on time required for charging calculated from the remaining power of an on-board battery 23 and information on homecoming time and makes determination accordingly at all times or periodically. When it determines that the on-board battery 23 would not be fully charged even when the end time of an inexpensive electricity charge time zone is exceeded, it lets boiling of water by water boiling means 10 be completed before the user returns home.
Abstract:
PROBLEM TO BE SOLVED: To provide a refrigerator that can reduce electricity costs charged for the amount of electricity consumed by performing defrosting, and to provide a defrosting control device and a defrosting control method.SOLUTION: The refrigerator 10a includes: a defrosting heater 8 that defrosts by heating; a defrosting-period predicted-value acquisition unit 24 that acquires a predicted value for the defrosting period, which represents the period in which defrosting is performed by means of the defrosting heater 8; an electricity-fee-information acquisition unit 25 that acquires electricity-fee information representing an electricity fee that changes over time; a defrosting time calculation unit 26 that computes a defrosting start time on the basis of the defrosting-period predicted value acquired by the defrosting-period predicted-value acquisition unit 24 and the electricity-fee information acquired by the electricity-fee-information acquisition unit 25 so that the electricity costs charged for the amount of electricity consumed by performing defrosting becomes no greater than a predetermined fee; and a defrosting control unit 28 that controls the defrosting heater 8 on the basis of the defrosting start time computed by the defrosting time calculation unit 26.
Abstract:
PROBLEM TO BE SOLVED: To provide a device and a method for appliance control capable of improving user convenience.SOLUTION: An appliance control device 10 includes: a time shift time calculation unit 14 for calculating a time shift time indicative of an operation start time or an operation completion time in which an electricity charge to be charged becomes no greater than a prescribed amount when an electric home appliance 20 is operated; a recalculation determination unit 17 for determining whether or not the time shift time calculated by the time shift time calculation unit 14 is to be modified; and a notification unit 18 for notifying the user, when the recalculation determination unit 17 determines the time shift time is to be modified, of the modification of the time shift time calculated first.
Abstract:
PROBLEM TO BE SOLVED: To solve the following problems: hot water in an electric water heater is not boiled even after the time zone of the lowest electricity rate elapses, and a charging start time for an on-vehicle battery is delayed because hot water is being boiled even after a user has gone home, so that charging start becomes difficult and a charging time becomes insufficient and hence an electric vehicle comes into no action when used in the morning.SOLUTION: Control determination means 11 previously completes boiling by boiling means 10 by the time to go home when it is determined that charging an on-vehicle battery 23 has not been completed even after the end time of a low electricity rate (night power zone) elapses, based on the time required for charging calculated from the residual quantity of the on-vehicle battery 23 and information about the time to go home.
