[Effects of the Invention]

[0007] According to the present invention, energy storage control can be efficiently performed from multiple power sources. [Brief explanation of the drawing]

[Figure 6] Figure 6 shows the functional configuration of the energy storage control device 100. [Figure 7] Figure 7 is a flowchart showing the operation of the energy storage control device 100. [Figure 8] Figure 8 shows an example of the hardware configuration of a power storage control device 100 according to one embodiment of the present disclosure. [Modes for carrying out the invention]

[0009] Embodiments of this disclosure will be described with reference to the attached drawings. Where possible, the same parts will be denoted by the same reference numerals, and redundant descriptions will be omitted.

[0010] Figure 1 is a diagram showing the system configuration of an energy storage system including the energy storage control device 100 of this disclosure. As shown in the figure, this energy storage system 10 is composed of the energy storage control device 100, wiring 110, a mobile battery 120, a radio wave power generation system 210, a light power generation system 220, a water power generation system 230, and a vibration power generation system 240. This energy storage system 10 is configured, for example, in a typical home. The energy storage control device 100 supplies power to power-consuming devices such as home appliances via the wiring 110 (outlets) or stores the power generated in each power generation system 210 to 240 based on the actions of residents in a typical home, or stores it in the mobile battery 120. The mobile battery 120 here includes not only portable batteries but also built-in storage batteries.

[0011] The radio wave power generation system 210, which includes Wi-Fi / LTE / 5G base stations, is always ON and therefore generates power 24 hours a day, which the energy storage control device 100 accepts. Similarly, the light power generation system 220 generates power the moment a light is turned ON and stops if it is OFF. The energy storage control device 100 accepts the power generated when the light is ON. Likewise, the water power generation system 230 generates power as soon as water flows in the kitchen, etc., and the energy storage control device 100 accepts that power. The vibration power generation system 240 generates power as soon as it detects vibrations caused by the movement of residents.

[0012] Each power generation system 210-240 generates electricity and stores it in a capacitor. The power storage control device 100 monitors the amount of stored power, and when a certain amount of power has accumulated, it processes the acquisition of that stored power. The power storage control device 100 accepts this power and can supply it not only to the mobile battery 120 but also to another location (the building's internal network).

[0013] Note that since the power generation system 230 using water generates relatively large power, the power storage control device 100 performs intelligent control to absorb power from the capacitor of the power generation system 230 with a large power storage amount. Also, if the power storage control device 100 is built into a wall surface, the power harvested can be used in the same way as a normal power outlet. In that case, since power is supplied from the power storage control device 100, it is necessary to provide a power outlet in the house.

[0014] Next, each of the power generation systems 210 to 240 will be described. FIG. 2 is a diagram showing the functional configuration of the power generation system 210 using radio waves. This power generation system 210 using radio waves is a system that can generate power based on radio waves within a home. As shown in the figure, the power generation system 210 using radio waves includes an antenna unit 211, a rectification / boost circuit 212, and a capacitor 213. The antenna unit 211 includes at least one of AM / FM 211a such as a radio, TV 211b, a base station 211c such as LTE / 5G for a mobile phone, and Wi-Fi 211d. Also, devices that emit radio waves other than these may be targeted.

[0015] The rectification / boost circuit 212 converts AC power into DC power, and the boost circuit is a circuit for increasing the voltage. More specifically, the rectification circuit is a circuit for converting alternating current (AC) power into direct current (DC) power. The boost circuit is a DC-DC converter for obtaining an output voltage higher than the input voltage, and when the voltage of the generated power is low, it performs a process for increasing the DC voltage to boost it and adjust it to the required voltage level.

[0016] In the present disclosure, the rectification / boost circuit 212 maximizes the combined power generation level by rectifying / boosting the signal obtained by the antenna unit 211 that receives radio waves in each frequency band.

[0017] The capacitor 213 is a circuit that stores and discharges the power processed by the rectification / boost circuit 212. The amount of power stored in the capacitor 213 up to the operation start level is monitored by the power storage control device 100, and when it reaches the operation start level (threshold value), it discharges to the power storage control device 100.

[0018] The power generation system 210 by radio waves stores the power processed as described above and discharges it to the power storage control device 100.

[0019] Figure 3 is a diagram showing the functional configuration of the power generation system 220 by light. This power generation system 220 by light is a system that can generate electricity based on the light emitted by household lighting and other sunlight. As shown in the figure, the power generation system 220 by light includes lighting 221, a photovoltaic sheet 222, and a capacitor 223.

[0020] The lighting 221 is a lighting fixture that emits light. When using sunlight as described above, the lighting 221 is not necessary.

[0021] The photovoltaic sheet 222 is composed of a member for converting light energy into electrical energy. For example, a dye-sensitized solar cell type in indoor photovoltaic power generation that can efficiently generate electricity even in a relatively low light intensity environment can be mentioned. Furthermore, the photovoltaic sheet 222 has a light absorption layer and contains a semiconductor material for absorbing light and converting it into electrical energy. As general materials, silicon, perovskite, or organic semiconductors are used. Also, electrodes are arranged on both sides of this light absorption layer to enable the generated electrical energy to be taken out to an external circuit. Generally, the photovoltaic sheet 222 is covered with a protective layer for protecting it from the external environment. This photovoltaic sheet is attached to the walls and ceilings inside the building and is arranged to be able to generate electricity at all times.

[0022] Capacitor 223 is a circuit that stores and discharges the electricity generated by the photovoltaic sheet 222. Capacitor 213 is monitored by the energy storage control device 100 until it reaches the operating start level, and when it reaches the operating start level (threshold), it is discharged to the energy storage control device 100.

[0023] In this way, the light-based power generation system 220 stores the electricity processed as described above and discharges it to the energy storage control device 100.

[0024] Furthermore, in this disclosure, the capacitor 223 for energy storage is installed on the wall of the house (building), and there are no elements other than the photovoltaic sheet 222 that would encroach on the interior of the house. The energy storage control device 100 monitors the amount of stored energy up to the activation level and discharges according to the amount of stored energy.

[0025] Figure 4 shows the functional configuration of a water-based power generation system 230. This water-based power generation system 230 is a system that can generate electricity based on the water flow used in a household. As shown in the figure, it is composed of a water flow generation unit 231, a piezoelectric element 232, and a capacitor 233.

[0026] The water flow generating unit 231 includes at least one of the washbasin 231a, shower 231b, and kitchen 231c, or other parts that generate water flow, such as a toilet. The water flow generating unit 231 generates water flow caused by the daily life of the household residents. For example, in the washbasin 231a, water flows into the drain when a resident washes their hands, generating a water flow.

[0027] The piezoelectric element 232 is positioned near the water flow generating unit 231 (for example, in a drain) and generates electricity by detecting water flow. This piezoelectric element 232 generates electricity by applying mechanical force, or in this disclosure, pressure or stress caused by water flow. Since it is a piezoelectric element, it is possible to automatically generate electricity only when water is flowing. Furthermore, by installing the piezoelectric element 232 at the outlet of a water pipe running from the roof of a building, it can catch the water falling from there and enable power generation on rainy days.

[0028] Capacitor 233 is a circuit that stores and discharges the electricity generated by the piezoelectric element 232. The amount of charge stored in capacitor 233 is monitored by the energy storage control device 100 until it reaches the operating start level, and when the operating start level (threshold) is reached, it is discharged to the energy storage control device 100.

[0029] In this way, the water-based power generation system 230 stores the electricity processed as described above and discharges it to the energy storage control device 100.

[0030] Figure 5 shows the functional configuration of the vibration-based power generation system 240. This vibration-based power generation system 240 is a system that can generate electricity based on the actions of residents in the home. As shown in the figure, the vibration-based power generation system 240 is composed of a piezoelectric element 242 and a capacitor 243.

[0031] The piezoelectric element 242 is located beneath the floor or other surfaces and generates electricity by detecting fluctuations in pressure (pressure due to a person's weight) caused by actions such as vibrations 241 (walking, jumping) performed by residents.

[0032] Capacitor 243 is a circuit that stores and discharges the electricity generated by the piezoelectric element 242. The amount of charge stored in capacitor 243 is monitored by the energy storage control device 100 until it reaches the operating start level, and when the operating start level (threshold) is reached, it is discharged to the energy storage control device 100.

[0033] In this way, the vibration-driven power generation system 240 stores the electricity processed as described above and discharges it to the power storage control device 100.

[0034] Each power generation system 210-240 implements MPPT (Maximum Power Point Tracking) control, and has the function of always tracking the maximum power point (MPP) of power generation even when external conditions change. Each power generation system 210-240 can efficiently store the generated electricity in a capacitor.

[0035] Next, the energy storage control device 100 will be described. Figure 6 is a diagram showing the functional configuration of the energy storage control device 100. As shown in the figure, the energy storage control device 100 is composed of a power generation monitoring unit 101, a selection unit 102, a switching unit 103, and a voltage / current adjustment unit 104.

[0036] The power generation monitoring unit 101 is a monitoring sensor that monitors the amount of electricity generated in each power generation system 210 to 240. In other words, the power generation monitoring unit 101 monitors the amount of stored energy in capacitors 213 and other components in each power generation system 210 to 240 in real time.

[0037] The selection unit 102 determines which power generation system 210 to 240 to use based on the amount of energy stored in each power generation system 210 to 240, and selects the determined power generation system. In other words, the selection unit 102 selects the power generation system 210 to 240 with the largest amount of energy stored in the capacitor 213, etc., as the system to be used preferentially. The selection unit 102 may also determine the priority of which power to discharge first based on the power generation status of each power generation system 210 to 240 (the amount of energy stored in each capacitor). For example, the selection unit 102 may determine that it will prioritize acquiring power from the vibration-based power generation system 240 when it is the most efficient.

[0038] The switching unit 103 is the part that electrically connects to one of the power generation systems 210 to 240 determined by the selection unit 102 and extracts power from the capacitor of that power generation system. For example, if the selection unit 102 selects the light-based power generation system 220, it performs the process of extracting the power stored in its capacitor 223.

[0039] The voltage / current adjustment unit 104 is the part that adjusts the voltage and current in the power supply taken from one of the predetermined power generation systems 210 to 240. In other words, the voltage / current adjustment unit 104 has a circuit that adjusts the voltage and current so that they are within a set range.

[0040] Next, the operation of the energy storage control device 100 will be explained. Figure 7 is a flowchart showing the operation of the energy storage control device 100.

[0041] The power generation monitoring unit 101 monitors the amount of charge stored in the capacitors in each power generation system 210 to 240 (S101).

[0042] Then, the selection unit 102 selects and switches to a preferred power generation system based on the monitored amount of stored energy (S103). In other words, the selection unit 102 identifies a power generation system whose amount of stored energy is equal to or greater than a predetermined value.

[0043] The voltage / current adjustment unit 104 adjusts the voltage and current in the power supply output from the switched power generation system (S104).

[0044] On the other hand, the voltage / current adjustment unit 104 may switch its output destination to charge a predetermined battery (a battery with LTO on the negative terminal) if the output power from the power generation systems 210-240 is small (S105).

[0045] Here, we will explain the selection criteria for the power generation system in process S103.

[0046] For example, the selection unit 102 determines and selects which power generation system 210-240 has the largest amount of stored energy in each capacitor. The switching unit 103 then switches from the selected power generation systems 210-240 to the selected power generation system. The selection unit 102 also determines which power generation system has a stored energy amount equal to or greater than a predetermined value, as detected by the power generation amount monitoring unit 101, and prioritizes switching to that power generation system.

[0047] The total capacity of the capacitors that can store energy varies depending on the power generation system. Therefore, the selection unit 102 may select the target power generation system according to the following criteria. For example, if the radio wave power generation system 210 has a storage capacity (generation) of several mW, the selection unit 102 will select power generation system 210. Also, if the light power generation system 220 has a storage capacity (generation) of several mW to several watts, the selection unit 102 will select this light power generation system 220. Also, if the vibration power generation system 240 has a storage capacity (generation) of several microwatts to several mW, the selection unit 102 will select power generation system 240. Also, if the water flow power generation system 230 has a storage capacity (generation) of several watts to tens of watts, the selection unit 102 will select the water flow power generation system 230.

[0048] If the amount of stored energy in the capacitors of each of these power generation systems 210 to 240 meets the above criteria, then the power generation systems 210 to 240 from which power can be extracted may be selected based on the following criteria (second criterion).

[0049] In other words, the selection unit 102 may determine which power generation system 210-240 to draw power from by observing the power generation trend (increase, slight increase, decrease, etc.) of the amount of charge stored in the capacitor detected by the power generation monitoring unit 101 within a certain range. The selection unit 102 may switch to the power generation system if the increase is 100mW or more every second. Alternatively, if the fluctuation is between 10mW and 100mW, it may continue with the selected power generation system or select a power generation system based on other criteria. Note that the above "every second" is just an example, and other time units may be used.

[0050] Specific methods for checking power generation trends include the following: One method is to measure power generation in real time using power meters (such as smart meters) connected to each power generation system 210-240. Another method is to install data loggers in each power generation system 210-240 to periodically record data such as power generation amount, voltage, and current, which allows for analysis of long-term trends. A third data analysis method involves analyzing past power generation data from each power generation system 210-240 to examine correlations with seasonality or weather conditions, thereby understanding trends in power generation efficiency under specific conditions.

[0051] Furthermore, the selection unit 102 may select a preferred power generation system 210 to 240 depending on the time of day. That is, the selection unit 102 may prioritize power generation systems based on radio waves or vibration, radio waves or indoor light, or radio waves, vibration, or indoor light during the daytime (for example, between 8 am and 3 pm), and prioritize power generation systems based on water flow, indoor light, radio waves, or vibration during the nighttime (for example, between 5 pm and 8 am).

[0052] Furthermore, the selection unit 102 may prioritize efficiency over the amount of stored energy. For example, every second, the selection may be made in the following order of priority: water flow power generation system 230 > vibration power generation system 240 > indoor light power generation system 220 > radio wave power generation system 210. As mentioned above, other time units may be used instead of "every second".

[0053] The above describes the priority switching process based on the amount of charge stored in the capacitors in each power generation system 210-240. However, instead of the amount of charge stored, the amount of power generated by each power generation system 210-240, or the power generation trend, may be used. Other criteria may also be used.

[0054] In that case, especially when applied to a photovoltaic power generation system 220, the selection unit 102 may implement MPPT (Maximum Power Point Tracking) control. This allows the selection unit 102 to always track the maximum power point (MPP) of power generation, even when external conditions change.

[0055] Furthermore, the selection unit 102 can configure an automatic tracking circuit with ultra-low power consumption, and the voltage / current adjustment unit 104 enables voltage conversion using an ultra-low power consumption voltage conversion circuit.

[0056] Next, the effects of the energy storage system 10 and energy storage control device 100 of this disclosure will be explained. In this disclosure, the power generation amount monitoring unit 101 of the energy storage control device 100 monitors the amount of electricity generated by multiple power generation systems (power generation devices) 210 to 240 that generate electricity in response to human activity within a building such as an ordinary home.

[0057] The selection unit 102 then selects a power generation system that meets the conditions (for example, the amount of charge stored in the capacitor and its threshold) based on the monitored amount of power generated. The switching unit 103 can switch the connection to that power generation system and supply power to the power output destination. For example, it can supply power to the wiring 110 or store the generated power in the mobile battery 120.

[0058] This configuration allows for efficient storage of electricity generated in each power generation system. Therefore, electricity can be generated stably and continuously in indoor living spaces, without being affected by the outdoor environment, and the electricity obtained can be efficiently supplied or stored.

[0059] In this disclosure, the power generation system is a combination of any of the following: power generation system 210, which is a power generation means based on radio waves; power generation system 220, which is a power generation means based on light; power generation system 230, which is a power generation means based on water flow; and power generation system 240, which is a power generation means based on vibration.

[0060] These power generation systems can generate electricity stably and continuously indoors, without being affected by the outdoor environment.

[0061] In this disclosure, the conditions are based on the amount of electricity generated by the power generation systems 210-240 or the amount of energy stored by the power generation systems 210-240. In these power generation systems 210-240, the generated electricity is stored in a temporary capacitor. Depending on the amount of energy stored in this capacitor, the energy storage control device 100 can select an appropriate power generation system 210-240 and store it in the mobile battery 120.

[0062] Furthermore, the conditions may also be based on the type of power generation system 210 to 240. For example, as described above, if the amount of charge stored in the capacitors of each power generation system 210 to 240 satisfies the conditions, a designated power generation system is selected from among the power generation systems 210 to 240 that are generating power efficiently. For example, in this disclosure, the water flow power generation system 230 is selected. Generally, the water flow power generation system 230 generates a large amount of power and generates power efficiently.

[0063] On the other hand, in this disclosure, if there is no power generation system among the power generation systems 210 to 240 that meets the conditions, the selection unit 102 selects power generation system 210, which is a low-power generation means that generates low power at all times. Power generation system 210 generates power 24 hours a day, and it is efficient to select power generation system 210 when the amount of stored energy of the other power generation systems 220 to 240 does not meet the conditions.

[0064] In this disclosure, the switching unit 103 switches to either the wiring 110 or the mobile battery 120. This allows power to be supplied to outlets that are normally located in a building.

[0065] The apparatus and method of this disclosure have the following configurations.

[0071] [6] If none of the power generation devices among the power generation devices can generate electricity while satisfying the conditions, the selection unit selects a power generation device that provides low-power generation at all times. The apparatus described in any one of [1] to [5].

[0075] The block diagram used in the description of the above embodiment shows functional units. These functional blocks (components) are realized by any combination of at least one of hardware and software. Furthermore, the method of realizing each functional block is not particularly limited. That is, each functional block may be realized using one device that is physically or logically coupled, or it may be realized using two or more physically or logically separated devices that are directly or indirectly connected (for example, using wired or wireless connections). A functional block may be realized by combining the above one device or the above multiple devices with software.

For example, a functional block (configuration part) that enables transmission is called a transmitting unit or transmitter. As mentioned above, the method of implementation is not particularly limited.

[0077] For example, the energy storage control device 100 in one embodiment of the present disclosure may function as a computer that processes the energy storage control method of the present disclosure. Figure 8 is a diagram showing an example of the hardware configuration of the energy storage control device 100 according to one embodiment of the present disclosure. The above-described energy storage control device 100 may be physically configured as a computer device including a processor 1001, memory 1002, storage 1003, communication device 1004, input device 1005, output device 1006, bus 1007, etc.

[0078] In the following explanation, the term "device" can be replaced with "circuit," "device," "unit," etc. The hardware configuration of the energy storage control device 100 may include one or more of the devices shown in the figure, or it may be configured to omit some of the devices.

[0079] Each function in the energy storage control device 100 is realized by loading predetermined software (programs) onto hardware such as the processor 1001 and memory 1002, which allows the processor 1001 to perform calculations, control communication by the communication device 1004, and control at least one of the reading and writing of data in the memory 1002 and storage 1003.

[0080] The processor 1001 controls the entire computer, for example, by running the operating system. The processor 1001 may be composed of a central processing unit (CPU) that includes interfaces with peripheral devices, control units, arithmetic units, registers, etc. For example, the selection unit 102 and the voltage / current adjustment unit 104 described above may be implemented by the processor 1001.

[0081] Furthermore, the processor 1001 reads programs (program code), software modules, data, etc., from at least one of the storage 1003 and the communication device 1004 into the memory 1002 and executes various processes accordingly. The program used is one that causes the computer to execute at least a part of the operations described in the above embodiment. For example, the selection unit 102 and the voltage / current adjustment unit 104 may be implemented by a control program stored in the memory 1002 and running on the processor 1001, and other functional blocks may be implemented similarly. The above-described various processes have been explained as being executed by one processor 1001, but they may be executed simultaneously or sequentially by two or more processors 1001. The processor 1001 may be implemented by one or more chips. The program may also be transmitted from a network via a telecommunications line.
