Description

  The present invention relates to an electric device provided with a charging means capable of supplying electric power to an electric vehicle or a storage battery, for example, an electric device such as a lighting device, an air conditioner, a hot water supply device, or a hot water storage device, at least a part of which is installed outdoors, and its control. It relates to methods and programs.

  A home will be described as an example. Electric bicycles are already widely used in homes as electric vehicles. In addition, the spread of electric vehicles and plug-in vehicles that can be easily charged at home is foreseen.

  Since these batteries are charged by a 100V or 200V AC power source at home, it is convenient if there is a 100V outlet or a charging device including the same in a bicycle parking lot or a parking lot. However, not all homes can provide such an environment, including support for existing houses.

  In the case of an electric bicycle that has become popular before an electric vehicle, it is common to remove the battery from the electric bicycle body, take it home, and charge it at an outlet in the home. If there is an outlet or a battery charger (for example, a charging stand) in the bicycle storage area at home, the battery can be charged on the spot, eliminating the need to carry the battery.

  In the case of an electric vehicle, the battery is large and heavy, so it cannot be removed and transported. You will have to use a charging outlet in the parking lot or charge it at a location other than your home (such as a charging stand).

  By the way, when charging at home, it is better to use it while paying attention to the time zone when the electricity usage fee is cheap. For example, in an all-electric house that handles 200V power, there is a fee system according to the time zone, and the power usage fee is from 9 o'clock to 7 am, about 9 yen per kW, before and after 17:00 to 23:00 From 7:00 to 10:00, it is about 23 yen, and from 10:00 to 17:00, it is about 28 to 33 yen. That is, the cheapest electricity usage fee from 23:00 to 7:00 am is about 1/3 of the electricity usage fee from 10:00 to 17:00.

  For this reason, some newly built houses equipped with a parking lot for electric vehicles have a charging outlet provided with a timer clock in the vicinity of the parking lot so as to be energized in a time zone when the electricity usage fee is reduced.

  There exists patent document 1 as an example of the electrical outlet installed in a parking lot, and a charging device. This is a lockable charging box 120 to prevent others from operating during charging, and is provided on the building wall facing the parking lot as shown in FIG. Since the operation unit and the connection unit of the charging apparatus are provided in the lockable charging box 120, it is possible to prevent a third party from operating and connecting without permission while sleeping or absent.

  Further, as in Patent Document 2 (FIG. 23), when the electric vehicle 108 is charged at a time when the electricity usage fee is reduced, the household electric appliances such as the electric water heater 105 and the microwave oven 109 are simultaneously used. As a result, the ampere breaker (current limiter) 104 may be cut off when the allowable current contracted in the house (contract power capacity) is exceeded.

In order to prevent this, the current (electric power used) of the entire home is monitored by the switchboard 103, and the electric current (electric power) for charging the household battery system 107 and the electric vehicle 108 is reduced before the ampere breaker 104 is cut off. Some prioritize the use of 110.

JP-A-9-107605 JP 2008-141924 A

A charging device like patent document 1 can install the alternating current power outlet for charge in such a suitable place with the intention of an electric vehicle if it is a house designed and built from now on .

  Another method is to wire the parking board from the distribution board in the house to the parking lot and provide a charging outlet outdoors.

  Here, when charging an electric vehicle, a current of a maximum of several tens A is passed in order to charge a storage battery having a larger capacity than an electric bicycle in a short time. Since the allowable current of a branch breaker in a general household is 15A or 20A, when the electric vehicle is charged, if the electric power is used by another electric device connected to the same branch breaker, the branch breaker may be cut off exceeding the allowable current. .

  If an existing branch breaker is shared between an existing electric device and an electric vehicle, the breaker may be blocked due to simultaneous use of charging and other electric devices. To fully charge an empty storage battery, it takes about 7 hours with a 100V power source and about 4 hours with a 200V power source. When using the same branch breaker electrical equipment for 4 to 7 hours, care must be taken. is there.

  Therefore, it is desirable that the branch breaker of the electric vehicle is a dedicated breaker rather than being used in combination with other devices. In other words, a branch breaker dedicated to electric vehicles is installed on the distribution board, and electricity is distributed from the ampere breaker, and then wiring is performed to a charging outlet installed outdoors. Also, an outdoor outlet operation means (energization on / off, energization timer) is provided near the parking lot.

  If this happens, electrical work will take some time and money, and if you buy an electric car, anyone can easily charge it at home.

  Moreover, if an electric vehicle or an electric bicycle is charged during a time period when the power usage fee is reduced, as described in Patent Document 2, it overlaps with the operation and operation of other home appliances, and the allowable current contracted in the house (contracted power capacity) ) May break the ampere breaker (current limiter).

  Especially if the charging time is late at night, if the ampere breaker shuts off, the lighting will not be used during the night and the toilet will be in trouble, the rice cooker that has been reserved for the timer to work early in the morning will not work and you will not be able to eat breakfast, and you will also work on an electric car・ It is expected that they will not be charged when going out.

  In other words, if the electric power used simultaneously at home increases due to the charging of the electric vehicle, the contracted power capacity with the power company so far becomes insufficient and the power capacity increases in many cases. For example, in an all-electric home, the basic charge will increase by several hundred yen every month if it exceeds 6kVA (equivalent to 60A at 100V).

  One method for avoiding this is to limit the current as in Patent Document 2. Since this method detects the current flowing through the ampere breaker of the distribution board and controls the charging outlet, wiring work is also required between the distribution board and the charging outlet of the electric vehicle.

  As described above, one of the attractions of electric cars is that the cost of unit mileage is lower than that of gasoline. However, if the cost required for the charging equipment is large, it may hinder the spread of electric vehicles.

  Patent Document 2 examines the case where an electric vehicle is charged at midnight, and uses electric appliances to reduce the electric power used for charging the electric vehicle before the ampere breaker shuts off. It is desirable to vary the power restriction target in consideration of usage of home appliances and electric vehicles, and power usage fees by time of day. For example, priority is given to charging of an electric vehicle according to the state of charge of the electric vehicle.

  Although the above is explained at home, the present invention is not limited to this, and is common to charging electric vehicles at bicycle parking lots and parking lots in shops, offices, factories, and facilities. The same thing happens when a storage battery is newly installed in a certain place and a charging means for charging it is required, not limited to an electric vehicle or an electric bicycle.

  An object of the present invention is to solve the above-described conventional problems, and it is an object of the present invention to easily provide a charging outlet in a place where a charging means is required without requiring a large-scale electrical work. In addition, the purpose is to suppress the increase in the basic charge of the electricity charge used for the cost of electric construction and contracted power capacity.

In order to solve the conventional problems, charging means with electrical equipment of the present invention is connected to an AC power source comprises a charging means capable of supplying power to the storage battery, and supplies to the charging means in accordance with the state of charge of the power storage pond Power supply control means for controlling power is provided. And when the power supply control means detects the state of charge of the storage battery and charges it in the constant current charging mode, the power supply control means gives priority to the power supply by the charging means over the power used by the electrical equipment, and detects the state of charge of the storage battery. When charging in a mode other than the constant current charging mode, priority is given to the power used by the electric device over the power supply by the charging means.

In the present invention, charging means is provided in an electric device such as a lighting device , an air conditioner, a hot water supply device, or a hot water storage device. Therefore, if the electric device with the charging means is installed in advance, an electric vehicle or an electric bicycle can be purchased later. When an electric vehicle or an electric bicycle is connected to the electric device with the charging means, it can be charged in a parking lot or a bicycle parking lot without requiring a large-scale electric work.

This and come, and controls the power supplied to the charging unit according to the state of charge of the battery, it is possible to control such as giving priority to more charge than the operation of the electric apparatus unit. And when charging in the constant current charging mode that requires a large amount of power, priority should be given to the power supply by the charging means over the power used by the electrical equipment, so that the storage battery with a low remaining charge can be charged smoothly. Can do.

In a fourth aspect based on the third aspect , the power supply control means is connected to the first and second charging means in a time zone in which the power usage fee is reduced by the power usage fee information by time zone of the AC power supply. If both of the storage batteries are in the constant current charging mode, the first charging means supplies power with priority over the second charging means.

  As a result, when the two storage batteries are both in the constant current charging mode during the time period when the power usage fee is reduced, the first charging means that supplies power to the storage battery of the electric vehicle is given priority to use the electric power for charging the electric vehicle. The price can be reduced.

A fifth invention is the invention according to any one of the first to fourth inventions, wherein the electric device with a charging means is connected to a small-scale power generator separately from the AC power source to obtain a power source, The time period during which the small-scale power generator is generating power is treated the same as the time period during which the electricity usage fee is reduced.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the embodiments.

(Embodiment 1)
FIG. 1 is a schematic diagram showing a residential building 1, an electric vehicle 2, and an electric device 5 with a charging means in a general house in Embodiment 1 of the present invention.

  In addition, although embodiment demonstrates at home, it is not restricted to this, You may charge an electric vehicle in a bicycle parking lot or a parking lot also in a shop, an office, a factory, a facility, etc. If it is a commercial facility or a public facility, the electric device with a charging means is not limited to a home appliance, but may be an electric device installed outdoors such as a user recognition device, an automatic payment machine, or a vending machine.

  The electric vehicle 2 includes a storage battery and an in-vehicle charging circuit 3 for charging the storage battery. The user charges the storage battery by controlling the current and voltage of the electric power obtained by inserting the charging plug 4 of the electric vehicle 2 into the outlet 8 with an in-vehicle charging circuit.

  As an electric device with a charging means for charging by inserting the charging plug 4, an electric device in which a part of the device is installed in a garden or garage of a residential building is assumed, and an outdoor unit 5a of an air conditioner or an electric hot water supply device is assumed. Illuminating equipment 5c such as an outdoor unit, a hot water storage tank 5b, and a garage is illustrated. These are provided with a charging outlet 8, and the electric vehicle 2 can be easily charged by inserting the charging plug 4 into the outlet 8. In addition, the structure provided with a part of vehicle-mounted charging circuit 3 in the electric equipment 5 side may be sufficient.

  As described above, since the charging means is provided in the electric device installed outdoors, if the electric device with the charging means is installed in advance, when the electric vehicle or the electric bicycle is purchased later, the charging device of the electric device is used. If it is connected to an electric car or electric bicycle, it can be charged at parking lots and bicycle parking lots without requiring extensive electrical work.

  Further, the electric device with a charging means is not limited to the lighting device, the air conditioning device, the hot water supply device, and the hot water storage device, and may be an electric device in which at least a part of the electric device main body function is installed outdoors. Since the charging plug of the electric vehicle is connected to an outdoor electric device, an extension cable that relays the power outlet and the plug does not need to be passed from the indoor to the outdoor, which is preferable for crime prevention.

  Next, FIG. 2 shows a block configuration diagram showing the electric device with charging means and its periphery according to the first embodiment of the present invention. The same functions as those in FIG. 1 are given the same numbers.

  An ampere breaker 12 is installed upstream of the AC power supply 11 (household 100V or 200V power supply), and this is cut off when the power used in the entire home exceeds the contracted power capacity, as in Patent Document 2 of the background art. Further, when power is supplied from the AC power supply 11 to the electric device 5, a branch breaker 13 (for example, an allowable current of 20A) is installed between the ampere breaker 12 and an overcurrent does not flow due to an abnormal operation or short circuit of the electric device. To do. The same applies to the other electric devices 14 and their branch breakers 15.

  The electric device 5 according to the first embodiment includes a charging unit / charging state detection unit 16 in the outdoor unit 27, and uses this to charge an electric vehicle equipped with a storage battery 3 such as an electric vehicle 2 or an electric bicycle outdoors. be able to. The connecting means 8 is a charging plug and an outlet, and may be charged by connecting to a storage battery other than the electric vehicle (the connecting means is not limited to the plug and the outlet).

  The detailed configuration of the electric device 5 with charging means will be described below.

  The total used power detecting means 17 is a wattmeter that detects the total used power in the entire electric device 5 including the power supplied to the charging means 16. The total power consumption detection means 17 may be a separate housing from the electric device 5 and may be an outlet-shaped adapter that communicates information on the detected total power consumption with the electric device 5.

The original function of the device owned by the electric device 5 is represented by a functional block 18 of the electric device and a control means 19 for controlling the functional block. For example, the function block 18 is an actuator such as a compressor or an inverter circuit, and is an air conditioner function for an air conditioner, a hot water supply function for an electric hot water supply device, a hot water storage function for a hot water storage device, and an illumination function for a lighting device. . The control means 19 is a microcomputer for controlling these functions and its peripheral part.

  In addition, in order to detect the electric power used in the original function of the electric device, the electric power used power detecting means 20 of the electric device is inserted into the power line of the function block 18 and the control means 19.

  An example of electric power used by an electric device is shown in FIG. Air conditioners and electric water heaters use a maximum of 1000 to 2000 W of power.

  And as a charging function with which the electric equipment 5 is provided, the charging means 16 which charges the storage battery 3 of the electric vehicle 2 connected to the connection means 8, and the control means 21 which controls it are provided. The charging unit 16 includes a charging state detection unit that detects a charging state of the storage battery 3 in addition to a voltage / current conversion function that generates a voltage / current optimum for charging according to the state of the storage battery 3. The state of charge of the storage battery and the charging voltage / current corresponding thereto will be described later.

  In addition, the power consumption detecting means 22 of the charging means is inserted into the power supply lines of the charging means 16 and the control means 21 in order to detect the power used in the charging function.

  For example, it takes about 8 hours with a household 200V-15A power source to charge a storage battery of a 16 kWh electric vehicle. In other words, when the functional blocks 18 and 19 of the electric device 5 and the charging means 16 and 21 are operated in combination, a maximum power of 4000 to 5000 W is used, and at this time, the branch breaker 13 is cut off.

  Therefore, in order to prevent the breaker 13 from being interrupted, the power used by the original function of the electrical equipment and the power used by the charging function are grasped, and both functions are operated simultaneously according to the power usage fee at that time. The electric device 5 includes power supply control means 23 that performs control to preferentially operate such as allocating and adjusting power to be used in both functions, or operating either one first.

  The power supply control means 23 includes a priority order storage means 24 for storing priorities for the functions and charging functions of the electrical equipment to be operated preferentially, and a power usage charge for storing power usage charge information for each time zone of the AC power supply 11. The operation of the electric device 5 is controlled so that the sum of the electric power used by the information storage means 25 and the electric device and the electric power used by the charging means is kept below a predetermined value (supplying capacity from the AC power supply 11). Power consumption calculating means 28 for controlling the power supplied to the power supply.

  As will be described later, the priority order storage unit 24 stores priorities according to the power usage of the electric equipment, the state of charge of the storage battery, and the power usage fee information for each time zone. In addition, a user-friendly priority order may be set, or the priority order storage unit 24 may learn according to the usage status of the electric device and the storage battery.

  The power usage fee information storage means 25 stores information on power usage fees by time zone in advance, or downloads power usage fees by time zone that changes according to power demand (not shown) via a communication network. In addition, as described later, it is conceivable to change the power usage fee when generating power from solar power generation or a fuel cell. FIG. 4 shows power usage fee information of the hourly rate system in an all-electric home that handles a 200V power source.

The used power calculation means 28 acquires the used power value of the functional block 18 of the electric device by the used power detection means 20 of the electric device, and the supplied power value from the charging means 16 to the storage battery 3 by the used power detection means 22 of the charging means. Then, the sum of the electric power used by the electric device and the electric power used by the charging means is calculated. Alternatively, the current value measured by the total power consumption detection unit 17 may be used as the sum of the power consumption of the electric device and the power consumption of the charging unit.

  As described above, the power consumption calculation means 28 obtains power consumption of the entire electric device 5 including charging, and controls power supply so that the total sum becomes a predetermined value or less.

  (A) The electric power used by the electric device and the electric power used by the charging means are detected, and the electric device 5 and the charging means 16 are operated simultaneously when there is a large margin of electric power with respect to the predetermined value.

  (B) When the electric power used by the electric device and the electric power used by the charging means are detected and there is little power margin with respect to the predetermined value, the electric power used by both the electric device 5 and the charging means 16 is allocated and adjusted. Drive at the same time.

  For example, if the electric device is an electric hot water supply device, the power consumption can be temporarily reduced by switching from the hot water boiling mode to the heat retaining mode. If the electrical device is an air conditioner, the operating mode, set temperature, and air volume can be reduced to temporarily reduce the power consumption. In the storage battery, the power (current and voltage) supplied can be reduced.

  For example, as shown in FIG. 5 (a), the storage battery is charged after reducing the power used by the electrical device at time t1.

  (C) Further, when there is no allowance for the predetermined value, the electric device 5 and the charging means 16 are operated at different times without being operated at the same time.

  For example, if the electric device 5 is operated first and is an electric hot water supply device, after completing the hot water supply in the hot water boiling mode, charging of the storage battery is started after the operation is completed. If it is an air conditioner, after heating and cooling the space to some extent in the rapid mode at the start of operation, charging of the storage battery is started after the operation is stopped.

  For example, as shown in FIG. 5B, the electric device is operated first, and the storage battery is charged after the operation of the electric device is finished at time t2.

  The predetermined value, which is the upper limit of the total power used, is initially set to be approximately equal to or less than the allowable current of the branch breaker 13 (or slightly more).

  The user instruction means 26 is a remote controller that remotely displays and controls the operation state of the electric device 5. The user instruction means 26 indicates the setting state and operation state of the electric device control means 19, the charging means control means 21, and the power supply control means 23. The user can set and control the operation of the electric device 5 and the charging of the storage battery 3.

  The communication medium between the electric device 5 and the user instruction means 26 may be infrared communication, wireless communication (radio wave), wired communication, power line communication, and the like. Carry it like a remote control for an air conditioner and use it at your favorite place.

  Here, the state of charge of the storage battery by the state of charge detection means 16 and the voltage / current control of charging corresponding thereto will be described with reference to FIG. FIG. 6 shows a charging sequence in the case of a lithium battery. The horizontal axis represents charging time, the vertical scale represents voltage, and the left scale represents charging current and charging capacity. As a unit, 1C is a current value at which discharge of a cell having a capacity of a nominal capacity value is constant-current discharged and the discharge is completed in exactly one hour.

  As shown in FIG. 6, when charging starts from a state where the charging state is close to 0 (left side of the graph), charging is initially performed with a constant current (1C current) (constant current charging mode). At this time, the voltage rises with charging, and the charging capacity is charged in proportion to the time.

  In FIG. 6, when the charging capacity is 75% (0.75 CAh) or more, charging is performed at a constant voltage (1C voltage) = 4.2 V (constant voltage charging mode). At this time, the current decreases with charge, and the charge capacity gradually reaches full charge (1.0 CAh) over time.

  That is, in the constant current charging mode, a large amount of power is required for charging, and the charging power is reduced when the mode is changed to the constant voltage charging mode.

  The constant voltage charging mode takes time because the current is reduced while keeping the voltage constant as shown in FIG. Therefore, there is a method called a pulse charge mode instead. This is because charging is performed by increasing the current exceeding 4.2V for a short time during charging, and then stops charging if the voltage is 4.2V or more, and if it is less than 4.2V, it is 4.2V again. Voltage is applied with the pulse of.

  As described above, the state of charge is detected, and charging voltage / current is controlled accordingly.

  In the present embodiment, this is described with an example in which this is performed by the charging unit / charged state detecting unit 16 in FIG. 2, but a configuration in which control is performed by the power input unit 3 on the electric vehicle 3 side is also possible. The power input means 3, the charging means / charge state detecting means 16, and the charging means control means 21 are connected via the connecting means 8, and the configuration is divided between the electric device 5 side and the electric vehicle 2 side. is there. Here, FIG. 2 will be described as an example.

  With the above configuration, the operation of the electric device with charging according to the first embodiment will be described with reference to the flowchart of FIG.

  In the first step S1, the power usage of the electrical device is detected by the power usage detection means 20 of the electrical device, the presence / absence of connection of the storage battery and the state of charge at the time of connection are detected by the charge state detection means 16, and the power usage fee information is stored. Electricity rate information at the time of charging including the present is acquired from the means 25, and the user's instruction content is acquired from the user instruction means 26. There may be no instruction from the user.

  Next, in S2, the priority order of the operation of the electric equipment 5 and the charging of the storage battery 3 of the electric vehicle is acquired from the priority order storage means 24, and the electric power usage, the charging state of the storage battery, and the electric power usage fee information acquired in S1. Judge the priority from Based on the determination, the power supply control means 23 determines the power supply control between the control means 19 of the electrical equipment and the control means 21 of the charging means.

  An example of the priority order is shown in FIG. From the left, the power consumption control (a) to (i) are output with the power used by the electrical equipment 5, the state of charge of the storage battery 3, and the power usage fee information as inputs.

  The power supply controls (a) to (d) are when the electric device 5 is operating and the power consumption is large, and the charging state at this time is the constant current charging mode (the charging capacity is 75% or less in FIG. 6). This is a case where a large amount of power is required even for charging.

  Here, referring to the power usage fee information, when the power usage fee is low, it is possible to charge the storage battery 3 when the power usage fee is low by giving priority to the charging of the storage battery 3 as shown in (a). When it is not charged, the electric device 5 continues to operate if possible.

  In addition, when it is a time zone where the electricity usage fee is not cheap, priority is given to the electric device 5 as shown in (b), so that the use of the electric device 5 is prioritized during the main life time and the storage battery 5 is charged at night. Leave the charging capacity as it is without charging.

  Further, when the electric device 5 is operating and the power consumption is large and the charging state at this time is the constant voltage charging mode or the pulse charging mode (the charging capacity is 75% or more in FIG. 3), charging is necessary. This is when the power is small.

  Here, as in (c) and (d), priority is given to the electric equipment regardless of the power usage fee information, and charging is performed with a small amount of necessary power by the charging means 16 if possible.

  On the other hand, the power supply controls (e) to (h) are when the electric device 5 is not operating or when the power used is small even though it is operating. At this time, referring to the power usage fee information, when it is a time zone where the power usage fee is cheap, priority is given to the charging of the storage battery 3 as in (e) and (g), so that the storage battery can be used when the power usage fee is low. When 3 can be charged, it is charged. When it is a time zone where the power usage fee is not cheap, the battery 3 is not charged as in (f) and (h), and a time zone where the power fee is cheap is waited.

  As shown in FIG. 8 (i), the electric device 5 is not connected to the storage battery 3, and even when the storage battery 3 is connected, charging is not necessary when fully charged, so the operation of the electric device 5 is prioritized.

  The control steps of FIG. 7 will be described below according to the priority order as described above.

  In step S2, priority determination and power supply control are determined as described above, and operation control of the electric device is performed by the control unit 19 of the electric device in S3. In S4, the charging means 16 is controlled by the charging means control means 21.

  In S5, the total power consumption detection means 17 detects the power consumption of the electrical equipment 5 (including the power consumption of the charging means), or the electrical equipment usage power detection means 20 and the charging means usage power detection means 22 The total power used by the charging means is detected.

  In S6, the power supply control means 23 compares the total used power with the allowable power that is a predetermined value, and if the used power is larger, the power supply control means 23 returns to S2 to review the power supply control (control and charging means of the electric device). Adjust control).

  As shown in S7, when the total power consumption is compared with the allowable power that is a predetermined value and the power consumption is smaller, the power supply has been successfully controlled. Therefore, the user instruction means (remote controller) 26 or the like is used. The user is notified of the operating state of the electrical device 5 and the amount of power used, and the state of charge of the storage battery 3, the charging time, and the amount of power supplied to the storage battery are notified.

  In addition, the charge state is detected by the charge state detection means 16, and current / voltage control is performed in accordance with the constant current charge mode, constant voltage charge mode, and pulse charge mode.

  In S8, when the charge state is detected by the charge state detection means 16, and the charge mode is switched from the constant current charge mode to the constant voltage charge mode or the pulse charge mode, the process returns to S1 to determine priority and limit power supply. Judge again. Similarly, when the operation mode of the electrical device 5 is switched, the notification is received from the control means 19 of the electrical device, and the process returns to S1 to determine the priority and the power supply limitation again.

  In S9, when the charging state detecting means 16 detects the completion of charging, the charging of the storage battery is finished and the process returns to S1, and the determination of the priority right and the power supply restriction are determined again. Similarly, when the operation of the electric device 5 is completed, the notification is received from the control means 19 of the electric device, the process returns to S1, and the priority determination and the power supply limitation are determined again.

  As in S8 and S9 above, when it is detected that the charging mode of the storage battery 3 has been changed or the charging has been completed by the charging state detection means 16 and the used power detection means 22 of the charging means, the process returns to S1 to determine priority. And determine power supply restrictions. Further, when it is detected that the operation mode of the electrical device has changed or the operation has been completed by the control unit 19 of the electrical device and the power consumption detection unit 20 of the electrical device, the process returns to S1 to determine the priority and limit the power supply. to decide.

  When the priority right determination and the power supply restriction are determined again after returning to S1, the power used by the electric device 5 is restricted by giving priority to the charging of the storage battery 3 (for example, in the case of the warming mode of the hot water supply device). Removes this restriction and operates the electric device 5 normally (switches to the boiling mode). Further, when the electric device 5 is in the operation waiting state (standby mode) by giving priority to the charging of the storage battery 3, the waiting state is canceled and the electric device is started to operate.

  Although not shown in the flowchart, the user instruction means 26 (remote controller) may return to S1 according to an instruction of the user during charging or operation of the electric device.

  Further, the operation may be performed according to the flowchart of FIG. 9 instead of the flowchart of FIG. That is, after determining the priority and controlling the power supply in S2, in S51, the power used by the original functional unit of the electric device 5 and the power used by the charging means are calculated and summed up to calculate the electric power with charging function. Calculate power consumption.

  For this purpose, the power consumption calculation means 28 stores in advance the relationship between the operation time (charging time) and the power consumption as the operation sequence for the power consumption of the functional block 18 and the charging means 16 of the electrical device.

  In addition, the power consumption calculation means 28 acquires information on the operation mode from the control means 19 of the electric equipment and information on the operation start from the power usage detection means 20 of the electric equipment, and the operation sequence of the functional block 18 of the electric equipment is obtained. The current state of the vehicle is determined, and the future operation time and power consumption are taken into consideration.

  Similarly, for the charging unit 16, the used power calculation unit 28 acquires information on the charging mode from the charging state detection unit 16 and information on the charging start from the used power detection unit 22 of the charging unit. The current state on the operation sequence is determined, and the future charging time and power consumption are considered.

  For example, in the case of an electric hot water supply device, the operation sequence of the electric device is a table of electric power consumption and a time for transition from the start of boiling water to the completion of boiling, and the transition to the heat retention mode.

  In the case of an air conditioner, the power consumption for each operation type such as cooling, heating, dehumidification, air blowing, power consumption corresponding to temperature setting and air volume change, and operation time and power consumption of sequential mode such as rapid mode and rest mode It is a table.

  The charging sequence of the storage battery is as shown in FIG.

In S61, the power supply control means 23 compares the total used power with the allowable power, and if the used power is larger, the power supply control means 23 returns to S2 to review the power supply control (control of the electric device and control of the charging means). Adjust the content).

  When the total used power is compared with the allowable power that is a predetermined value and the used power is smaller, the allocation of power supply control is successful, so that the operation control of the electric equipment and the charging means are performed in S31 and S41. Control.

  The advantage of the flowchart of FIG. 9 is that the power adjustment is performed while the electric device and the charging unit are operated in FIG. 7, whereas the operation of the power adjustment is completed in FIG. Further, the detection means 20 for detecting the power used by the electric device, the power usage detection means 22 for detecting the power usage of the charging means, and the total power consumption detection means 17 are not required.

  Hereinafter, Embodiments 2 to 5 of the present application will also be described based on the flowchart of FIG. 7, but these may be switched in the order of S <b> 3 to S <b> 6 as in the flowchart of FIG. 9.

  As described above, the first embodiment has the following effects.

  (1) It is provided with a charging means 16 that can be connected to an AC power source and can supply power to the storage battery 3, and is at least one of the power usage of the electrical device 5, the state of charge of the storage battery 3, and the power usage fee information according to the AC power supply time zone Power supply control means 28 for controlling the power supplied to the charging means according to the above.

  As a result, the charging device 16 is provided in the electric device 5. Therefore, if the electric device 5 with the charging device is installed in advance, when the electric vehicle or the electric bicycle is purchased later, the electric vehicle is connected to the charging device 16 of the electric device. Or electric bicycles can be connected and charged at parking lots and bicycle parking lots without the need for extensive electrical work.

  In addition, the power supplied to the charging means 16 according to the power used by the operation of the electrical equipment main body (the functional block 18 and the control means 19 of the electrical equipment), the state of charge of the storage battery 3, and the power usage fee information according to time zone of the AC power supply Because it controls, it prevents the breaker from shutting off by using too much electric power during charging, selecting the time zone where the power usage fee is low, or charging depending on the charging state of the storage battery 3 Control such as giving priority to charging over the operation of the electric device main body becomes possible.

  (2) The electric device 5 with charging means is an electric device that is at least partially installed outdoors, such as a lighting device, an air conditioner, a hot water supply device, or a hot water storage device, and is charged outdoors without requiring extensive electrical work. It becomes possible. Further, since it is connected to an outdoor electric device, it is not necessary to pass an extension cable connected to a power outlet from indoor to outdoor, which is preferable in terms of crime prevention.

  (3) When the power supply control means 28 detects the state of charge of the storage battery and charges the battery in the constant current charging mode, the power supply control means 28 selects the time zone when the power usage fee is reduced according to the power usage fee information classified by time zone, and the charging means Since the electric power is supplied from the power source, it is possible to reduce the power usage fee for the constant current charging mode that requires a large amount of power during charging.

  (4) The power supply control means 28 calculates the sum of the power used by the electric equipment with the charging means (the functional block 18 of the electric equipment and the control means 19) and the power supplied from the charging means 16 to be less than the supply capacity of the AC power supply. Control the operation of the electrical device 18 to maintain, or (and) control the power supply by the charging means 16.

As a result, when the electric device is used during charging, the breaker can be prevented from being interrupted by controlling the operation of the electric device and the power supply of the charging means so as not to exceed the supply capacity of the AC power supply (including the branch breaker). .

  (5) When the power supply control means 28 detects the state of charge of the storage battery 3 and charges it in the constant current charging mode, the power supply control means 28 uses the charging means rather than the power used by the electrical equipment (the functional block 18 of the electrical equipment and the control means 19). Priority is given to the power supply by No. 16, and the sum of the electric power used by the electric device with the charging means and the electric power supplied from the charging means is kept below the supply capacity of the AC power supply.

  As a result, when charging in the constant current charging mode that requires a large amount of power, the power supply by the charging means is given priority over the power used by the electrical equipment so as not to exceed the supply capacity of the AC power supply (including the branch breaker). The storage battery whose remaining charge is low can be charged smoothly.

  (6) The power supply control means 28 is a charging means rather than the power used by the electrical equipment (the functional block 18 of the electrical equipment and the control means 19) in the time zone when the power usage fee is reduced by the time-based power usage fee information. Priority is given to the power supply by No. 16, and the sum of the electric power used by the electric device with the charging means and the electric power supplied from the charging means is kept below the supply capacity of the AC power supply.

  As a result, in the time period when the electricity usage fee is cheaper, the power supply by the charging means is prioritized over the electricity used by the electric device to reduce the charging cost, and when using the electric device during charging, the AC power supply (branch) It is possible to prevent the breaker from being interrupted by controlling the operation of the electrical equipment and the power supply of the charging means so as not to exceed the supply capacity of the breaker (including the breaker). For example, when a time zone in which the nighttime power usage fee is reduced is used, a storage battery (such as an electric vehicle) can be used from the next morning.

  (7) The power supply control unit 28 is configured to use the electric device (the function block 18 of the electric device and the control unit) rather than the power supply by the charging unit 16 except for the time period in which the power usage fee is reduced by the time-based power usage fee information. Priority is given to the power used in 19), and the sum of the power used by the electric device with the charging means and the power supplied from the charging means is maintained below the supply capacity of the AC power supply.

  As a result, it can be used without stress when the user wants to use the electric device by giving priority to the electric power used by the electric device over the power supply by the charging means except during the time period when the electric power usage fee is reduced. When charging while using the electric device, the breaker can be prevented from being interrupted by controlling the operation of the electric device and the power supply of the charging means so as not to exceed the supply capacity of the AC power supply (including the branch breaker). For example, in a time zone in which the daytime power usage fee is not cheap, in order to reduce the charging cost, charging is not performed as much as possible until the time zone in which the power usage fee is low.

(Embodiment 2)
Next, a second embodiment of the present invention will be described. With respect to the same means as in the configuration of the first embodiment (FIG. 2), the number assigned is the same as in the first embodiment, and a detailed description is omitted.

  In the second embodiment, the power supply control in FIG. 8 in the first embodiment is shown in FIG. That is, as shown in (a ′), (c ′), (e ′), and (g ′) of FIG. 10, priority is given to charging (or electrical equipment) in a time zone where the power usage fee for each AC power source is low. The electric power that is not prioritized is operated (or the storage battery is charged), and the total power used is adjusted so as to be approximately equal to the supply capacity of the AC power supply.

  Therefore, in the configuration of FIG. 2, the power consumption calculation means 28 obtains the current power consumption and the future power consumption of the entire electric device 5 including charging, and the sum is set to a predetermined value (= AC power supply capability). The following power supply control is performed so as to be approximately equal.

  (A) The electric power consumption detecting means 20 detects electric power consumption (electrical device functional block 18 and electric equipment control means 19), and the charging power usage detecting means 22 uses the charging power. , And the electric power 5 and the charging means 16 are operated simultaneously when the total electric power used is less than or equal to a predetermined value in a time zone when the electric power usage fee is low. Here, instead of calculating the total power consumption, the total power consumption detected by the total power detection means 17 may be used.

  (B) When the electric device 5 and the charging means 16 are normally operated simultaneously at a time when the electric power usage fee is low, if the total amount of electric power used is equal to or greater than a predetermined value, both the electric device 5 and the charging means 16 The electric power to be used is allocated and adjusted so as to be almost equal to a predetermined value.

  For example, if the electric device is an electric hot water supply device, the electric power supplied to the charging means is increased when the hot water heating mode is switched from the hot water heating mode to the heat retention mode and the electric power used is reduced. If the electric device is an air conditioner, the power supplied to the charging means is increased or decreased when the operating mode, set temperature, or air volume is changed to change the power used. When the power charged by the storage battery changes, the power used by the electrical device is increased or decreased.

  For example, as shown in FIG. 11A, when the electric power used by the electric device to be prioritized decreases at time t3, the charging power of the storage battery is increased.

  (C) When the power used for charging a preferred storage battery (or driving an electrical device) decreases during a period when the electricity usage fee is low, drive the non-prioritized electrical device (or charge the storage battery). Use power as much as possible below the specified value.

  For example, the storage battery is preferentially charged, and the electric device 5 is operated if there is a surplus in usable power. In the case of an electric hot water supply device, the hot water is kept in a warming mode, and in the case of an air conditioner, the object and the surrounding environment are held as in a ventilation or air cleaning mode. Moreover, the maintenance operation | movement of an apparatus like the internal washing | cleaning of an air-conditioner apparatus may be sufficient. Alternatively, priority is given to the operation of the electric equipment, and the storage battery is charged if there is a surplus in usable power.

  For example, as shown in FIG. 11 (b), the storage battery is charged, and the operation of the electric device is started when there is a surplus in the usable power at time t4 due to a decrease in the charging power.

  The operation of the electric device with charging according to the second embodiment will be described with reference to the flowchart of FIG. Flowchart of Embodiment 1 The same steps as those in FIG. 7 are designated by the same numbers as in Embodiment 1 and will not be described in detail.

  In S6 in FIG. 12, the power supply control means 23 compares the allowable power so that the total used power is less than or equal to a predetermined value, and then adds S62 to determine whether the total used power can be adjusted. To do.

  That is, it inquires of the charging state detection means 16 and the control means 21 of the charging means whether the use power can be adjusted by increasing the charging power supplied to the storage battery. Further, the control unit 19 of the electric device is inquired whether the electric power used can be adjusted by operating the electric device. If the power consumption can be adjusted, the process returns to S2 to adjust the power supply control.

  In the constant current charging mode of FIG. 6 where the state of charge of the storage battery is large, the power required for charging is large, so that it can be used for adjustment when the available power is large. In addition, when the charging state is constant voltage charging mode or pulse charging mode, the power required for charging is small, so that it can be used for adjustment even when the available power is small.

  As described above, the second embodiment has the following effects.

  (1) The power supply control means 23 uses the power used by the electrical equipment (the functional block 18 of the electrical equipment and the control means 19) and the charging means 16 in the time zone when the power usage fee is reduced by the time-based power usage fee information. The sum of the power supply supplied from the power source is calculated, and the operation of the electrical equipment and the power supply by the charging means are controlled so as to be approximately equal to the supply capacity of the AC power supply.

  As a result, the sum of the electric power used by the electric device with charging means and the electric power supply supplied from the charging means is calculated so that the electric device can be operated as much as possible and the storage battery can be charged using the time period when the electricity usage fee is cheap. In addition, the electric equipment can be operated and charged at a low power usage fee by using it almost equal to the supply capacity of the AC power supply.

  (2) When the power supply control means 23 calculates the sum of the power used by the electrical equipment (the functional block 18 of the electrical equipment and the control means 19) and the power supplied from the charging means 16 and is less than the supply capacity of the AC power supply. Then, power is supplied by the charging means 16 so that the total power approaches the supply capacity.

  As a result, when there is a surplus in the power supply capacity of the AC power supply in the time zone when the power usage fee is cheaper, it is possible to charge at a low power usage fee by increasing the power usage as much as possible by supplying power by the charging means. .

(Embodiment 3)
Next, a third embodiment of the present invention will be described. As for the same means as in the first embodiment, the number to be assigned is the same as in the first embodiment, and the detailed description is omitted.

  In the third embodiment, as shown in FIG. 13, a fixed installation type storage battery 9 is connected to the electric device (hot water storage tank 5 b) of FIG. 1, and even when the electric vehicle 2 is out and not in a parking lot, Charging is performed, and the in-vehicle storage battery 3 is charged from the storage battery 9 after the electric vehicle 2 returns to the parking lot.

  In this way, by using the storage battery 9 for temporary power storage, the battery can be charged even when the electric vehicle 2 is not in the parking lot at a time when the power usage fee is low. In addition, when power is supplied from the storage battery 9 to the in-vehicle storage battery 3, there is an advantage that the power can be increased and charging can be performed in a short time. For example, the maximum AC power at home is 200V-15A, but if it is supplied from the storage battery 9 at twice the voltage (or twice the current), the charging time can be reduced to about half.

  Therefore, in the configuration diagram of the third embodiment, as shown in FIG. 14, the storage battery 9 and its charging system and discharging system are added to the first embodiment (FIG. 2).

  The charging system of the electric vehicle in the first embodiment is referred to as first charging, and the charging system of the storage battery 9 is newly referred to as second charging.

  In FIG. 14, the used power detection means of the first charging means, the first charging means / charging state detection means, and the control means of the first charging means are the same as those in FIG. Grant as it is.

The power consumption detecting means of the second charging means, the second charging means, the charging state detecting means, and the control means of the second charging means are newly designated 30, 31 respectively. Moreover, the power conversion means 32 which enlarges electric power so that it can charge in a short time when supplying electric power from the storage battery 9 to the vehicle-mounted storage battery 3 is provided.

  As a charging function newly provided in the electric device 5 for the storage battery 9, a charging unit for the storage battery 9 and a second charging unit / charge state detection unit / control unit 30 that are control units thereof are provided. The second charging means / control means 30 includes a charging state detection means for detecting the charging state of the storage battery 9 in addition to the voltage / current conversion function for generating the optimum voltage / current for charging according to the state of the storage battery 9. Prepare.

  If the storage battery 9 is a lithium battery similar to the storage battery 3, the charging state and the charging voltage / current corresponding thereto can be made the same as the charging sequence of FIG.

  Further, in order to detect the power used for the charging function of the storage battery 9, the used power detection means 30 of the second charging means 31 is inserted into the power supply line of the second charging means / control means 30. The total used power detecting means 17 measures the sum of the used power of the electric equipment, the used power of the first charging means, and the used power of the second charging means.

  The power conversion means 32 supplies the power charged in the storage battery 9 to the first charging means 16, and at this time performs power conversion to convert current or power. That is, the charging time is shortened by increasing the voltage in the constant current charging mode and the pulse charging mode and increasing the current in the constant voltage charging mode.

  The power supply means 23 controls and supplies power to the charging means / control means 30 of the second charging means in addition to the control and power supply of the control means 18 of the electrical equipment and the control means 21 of the first charging means. Then, the power conversion means 32 is controlled. That is, the operation of the electric device 5, the charging of the storage battery 3 of the electric vehicle, the charging of the storage battery 9, and the charging from the storage battery 9 to the storage battery 3 of the electric vehicle are integratedly controlled.

  The operation of the electric device with charging according to the third embodiment will be described with reference to the flowchart of FIG. Flowchart of Embodiment 1 The same steps as those in FIG. 7 are designated by the same numbers as in Embodiment 1 and will not be described in detail.

  In S11, in addition to S1 of FIG. 7, the charged state of the storage battery 9 is detected.

  In S42, charging control of the first charging unit 16 and the second charging unit 31 is performed instead of S4.

  In S52, instead of S5, the power used by the electric device 5, the first charging unit 16, and the second charging unit 31 and the total power used are detected.

  In S71, instead of S7, the operating state of the electric device 5, the charging state of the first charging unit 16, and the power receiving state of the second charging unit 31 are notified.

  Illustration of S8 and S9 in FIG. 7 is omitted.

  S20 is added and charging is performed by returning to S11 until the storage battery 9 is fully charged.

  S21 is added, and after full charge, it is confirmed that the electric vehicle 2 is in a state that can be charged by the connecting means 8, and it is confirmed whether there is a trigger for charging.

  The following are possible triggers for charging.

  (A) When the user gives an instruction from the user instruction means (remote controller) 26.

  (B) When the storage battery 3 is not sufficiently charged before the electric vehicle 2 is used. Here, the usage time of the electric vehicle 2 is based on the past usage history (usage time and mileage) of the electric vehicle 2 in which the usage schedule of the electric vehicle 2 is input by the user instruction means 26 or the like. Can predict.

  (C) When the predetermined time is reached. For example, when it is 10 am on weekdays. When it is 8am on a holiday.

  (D) When the charge capacity of the storage battery 3 of the electric vehicle 2 becomes a predetermined value or less. For example, when the constant current charging mode is set to 75% or less in FIG.

  If there is a charging trigger as described above, in S22, the electric power charged in the storage battery 9 is converted by the power conversion means 32, and the storage battery 3 of the electric vehicle is charged from the first charging means 16. The time required for this charging is shorter than the power supply from the AC power supply 11.

  Note that the priority determination in S2 is the same as in the first embodiment. The priority order of the operation of the electric device 5, the charging of the storage battery 3 of the electric vehicle, and the charging of the storage battery 9 is acquired from the priority storage means 24, and the electric power usage of the electric device, the charging state of the storage battery, and the power usage fee information Determine priority. Then, based on the determination, the power supply control means 23 performs power supply control of the control means 19 of the electrical equipment, the control means 21 of the first charging means, and the control means 31 of the second charging means.

  The priority order is basically the same as in the first embodiment (FIG. 8). When “charging” is performed by the power supply control in FIG. 8, there are two chargings, the storage battery 9 and the storage battery 3 of the electric vehicle. If only one of the storage batteries can be charged, that storage battery is the target of charging.

If both storage batteries can be charged,
(B) If the power usage fee for each time zone is low, charging is performed with priority given to the storage battery in the constant current charging mode with the higher power usage than the storage battery in the constant voltage charging mode.

  (A-1) In the above (A), if both storage batteries are in the constant current charging mode, the storage battery 3 of the electric vehicle is charged with priority over the storage battery 9.

  (B-2) In the above (B), if both the storage batteries are in the constant voltage charging mode and the pulse charging mode, the storage battery 9 is charged with priority over the storage battery 3 of the electric vehicle.

  (B) If the power usage fee for each time zone is not low, charging is performed with priority given to the storage battery in the constant voltage charging mode and the pulse charging mode with a lower usage power than the storage battery in the constant current charging mode.

  (B-1) In (B) above, if both storage batteries are in the constant voltage charging mode and the pulse charging mode, the storage battery 9 is charged with priority over the storage battery 3 of the electric vehicle.

  (B-2) In (B) above, if both storage batteries are in constant current charging mode, the storage battery 3 of the electric vehicle is charged with priority over the storage battery 9.

  As described above, the third embodiment has the following effects.

  (1) A first charging means 16 that can be connected to an AC power source and can supply power to the storage battery 3 of the electric vehicle 2 and a second charging means that supplies power to a storage battery 9 different from the storage battery 3 of the electric vehicle 2 31 in the electric device 5, and the first and second charging according to at least one of the electric power used by the electric device 5, the state of charge of the storage batteries 3 and 9, and the power usage fee information according to the time zone of the AC power supply 11. The power supply control means 23 for controlling the power supplied to the means 16 and 31 and the power conversion means 32 for converting the power charged in the storage battery into electric power equal to or higher than the AC power source when supplying the electric power to the electric vehicle. It is an electric device with a charging means.

  Accordingly, the second charging means supplies power from the AC power source to the storage battery in accordance with the power usage of the electrical equipment, the state of charge of the storage battery, and the power usage fee information according to the time zone of the AC power source. Then, power is supplied from the storage battery to the electric vehicle for charging. At this time, since the power charged in the storage battery by the power conversion means is converted into power higher than the AC power supply and supplied to the electric vehicle, the battery can be charged in a shorter time than the direct power supply from the AC power supply to the electric vehicle.

  (2) The power supply control means 23 is configured such that one of the storage batteries connected to the first and second charging means 16 and 31 is constant-current charged in a time zone when the power usage fee is reduced by the time-based power usage fee information. In the mode, power is supplied to the storage battery in the constant current charging mode with priority over the storage battery in the constant voltage charging mode or the pulse charging mode.

  This makes it possible to lower the power usage fee by prioritizing charging of the storage battery in the constant current charging mode that requires a large amount of power for charging in a time zone when the power usage fee is reduced.

  (3) The power supply control means 23 is configured so that both the storage batteries connected to the first and second charging means 16 and 31 are in the constant current charging mode in the time zone when the power usage fee is reduced by the power usage fee information classified by time zone. If so, the first charging means supplies power with priority over the second charging means.

  As a result, when the two storage batteries are both in the constant current charging mode during the time period when the power usage fee is reduced, the first charging means that supplies power to the storage battery of the electric vehicle is given priority to use the electric power for charging the electric vehicle.

(Embodiment 5)
Next, a fifth embodiment of the present invention will be described. As for the same means as in the first embodiment, the number to be assigned is the same as in the first embodiment, and the detailed description is omitted.

  In the configuration diagram of the fifth embodiment, as shown in FIG. 19, a small-scale power generation device 40 (solar power generation device, fuel cell, geothermal power generation, wind power generation, etc.) is added to the first embodiment (FIG. 1).

  As shown in FIG. 20, the electric power generated by the small-scale power generation device 40 is supplied to the electric device 5 through the branch breaker 13 and used as a substitute power source for the AC power source 11. Then, the power generation amount of the small-scale power generation device 40 is detected by the power generation amount detection means 41 so that the power usage fee for each time zone is reduced during the time during which the power generation amount of the small-scale power generation device 40 is generated, and the power usage fee information storage means 25.

  The power usage fee information storage means 25 reduces the power usage fee when there is a power generation amount (for example, 0 yen), and uses the normal power usage fee of the AC power supply 11 when there is no power generation amount.

  The power supply control means 23 compares the total value of power used by the total power consumption detection means 17 with the amount of power generated by the power generation amount detection means 41 so that the total value of power usage does not exceed the power generation amount. Control.

  The operation of the power supply selection device according to the fifth embodiment will be described with reference to the flowchart of FIG. For the same steps as those in the flowchart (FIG. 7) of the first embodiment, the number to be given is the same as that of the first embodiment, and the detailed description is omitted.

  S14 is added, and the power generation amount detection means 41 detects the power generation amount of the small-scale power generation device 40 and inputs it to the electricity usage fee information storage means 25 to change the power usage fee accompanying power generation.

  In S63, instead of S6, the power supply control means 23 compares the total used power with the generated power that is a predetermined value, and if the used power is larger, the process returns to S2 to review the power supply control (electrical equipment) Control and control of charging means). S64 will be described later.

  In S72, instead of S7, the user instruction means (remote control) 26 or the like informs the user of the operating state and power consumption of the electric device 5, and supplies the storage battery 3 to the storage battery, the charging state, the charging time, and the storage battery. In addition to the power amount, the power generation amount of the small-scale power generation device 40 and the difference between the power consumption amount and the power generation amount are notified.

  However, S64 is added because it is desired to use and store the power generated by the small-scale power generator as much as possible. This is similar to S62 of the second embodiment (FIG. 12). That is, it inquires of the charging state detection means 16 and the control means 21 of the charging means whether the use power can be adjusted by increasing the charging power supplied to the storage battery.

  The control unit 19 of the electric device is inquired whether the electric power used can be adjusted by operating the electric device. If the power consumption can be adjusted, the process returns to S2 to adjust the power supply control.

  As described above, the fifth embodiment has the following effects.

(1) The electric device 5 with the charging means is connected to the small-scale power generation device 40 separately from the AC power source to obtain the power source, and the time zone in which the small-scale power generation device 40 generates power in the power usage fee information by time zone Is treated the same as the time when electricity usage charges are cheaper.

  As a result, when a small-scale power generation device such as solar power generation or fuel cell is generating and supplying power, the power usage fee of the generated power is reduced and power is supplied to the storage battery from the electric device with charging means can do.

  (2) The power supply control means 23 uses the electric power used by the electrical equipment (the functional block 18 of the electrical equipment and the control means 19) and the charging means 16 in the time zone when the power usage fee is reduced by the power generation of the small-scale power generation device 40 The sum of the power supply supplied from the power source is calculated, and the operation of the electric equipment and the power supply by the charging means are controlled so as to be substantially equal to the power generation amount of the small-scale power generation device 40.

  In this way, the total power used by the electrical equipment with charging means and the power supply supplied from the charging means are calculated so that the generated power can be operated as much as possible and the storage battery is charged. By doing so, the electric device can be operated and charged at a low power usage fee.

  In addition, in the said embodiment, the merit which combines the charging means of a storage battery with an electric equipment is supplemented.
