Description

Direct solar panel storage battery

[0001] The present invention relates to a direct solar panel storage battery that integrates a solar panel and a secondary battery electrically connected to the solar panel.

[0002] In conventional solar panel systems, the power generated by solar panels is transmitted via electrical wires. Technologies for storing power in large-capacity storage batteries using solar chargers and power conditioners are becoming more common, and technological development is progressing every day. However, transmitting the power generated by solar panels requires a large number of electrical wires, which requires a lot of time and money in terms of installation, and also requires a large amount of space. Therefore, one way to eliminate the need for electrical wires is to integrate the solar panels with the storage batteries.

[0003] For example, Patent Document 1 discloses a power supply device for electric fences in which a solar panel is integrally provided in a housing, and inside the housing are provided a rechargeable battery, a boost circuit connected to the battery to generate high-voltage pulses, and a regulator that controls the voltage input from the solar panel to appropriately charge the battery, and an output terminal connected to the boost circuit is provided on the outer surface of the housing.

[0004] Patent No. 6865487

[0005] Patent Document 1 describes a method of integrating a solar panel with a storage battery, but when supplying power from the secondary battery to an external device, power transmission via a conductor is required, which leaves the issue of taking a lot of time and cost in terms of equipment.

[0006] In view of the above circumstances, the present invention aims to provide a direct solar panel storage battery that integrates a solar panel with a secondary battery connected to the solar panel and supplies the generated power obtained from the solar panel via wireless power supply without using wires.

[0007] The direct solar panel storage battery of the first invention is a direct solar panel storage battery that integrates a solar panel and a secondary battery electrically connected to the solar panel, wherein the secondary battery comprises a contact electrode portion that is arranged in contact with the solar panel, and an opposing electrode portion that pairs with the contact electrode portion, and the secondary battery is formed in the shape of a thin plate on the back surface or inside the solar panel by the contact electrode portion and the opposing electrode portion.

[0008] According to the direct solar panel storage battery of the first invention, the solar panel and the secondary battery connected to the solar panel are formed as an integrated unit (the secondary battery is formed in the form of a thin plate on the back surface or inside the solar panel), which is expected to reduce the time and cost burden in terms of equipment required when introducing solar power generation.

[0009] The direct solar panel storage battery of the second invention is characterized in that, in the first invention, it comprises heat dissipating carbon arranged on the back surface of the secondary battery, and an induction antenna for both receiving and transmitting power arranged on the back surface of the heat dissipating carbon and electrically connected to the secondary battery.

[0010] The direct solar panel storage battery of the third invention is characterized in that, in the second invention, an oscillator that generates an AC magnetic field for wireless power supply is attached to the edge of the solar panel, and the oscillator and the induction antenna form a wireless power supply unit.

[0011] According to the direct solar panel storage batteries of the second and third inventions, the power generated by the solar panel can be supplied wirelessly via an induction antenna without using wires, which is expected to reduce the time and cost burden required for equipment when introducing solar power generation.

[0012] The direct solar panel storage battery of the fourth invention is the same as that of the first invention, wherein the secondary battery comprises a protruding connection electrode portion that protrudes from the edge of the solar panel, and a fitting connection electrode portion into which the protruding connection electrode portion fits at the edge of the solar panel, and by fitting the protruding connection electrode portion with the fitting connection electrode portion, adjacent secondary batteries are electrically connected and the solar panels are arranged continuously.

[0013] According to the direct solar panel storage battery of the fourth invention, by making the solar panels into a structure that can be easily connected like blocks, the burden of assembly work is reduced and it is expected that large-capacity electricity storage will be possible.

[0014] A direct solar panel storage battery of a fifth invention is any one of the first to fourth inventions, characterized in that the secondary battery is a capacitor battery, and the capacitor battery is formed in a film shape.

[0015] According to the direct solar panel storage battery of the fifth invention, by using a capacitor battery as the secondary battery, it is possible to store a large amount of electricity, and by using a film-shaped solar panel, it is lightweight and can be bent freely, making it possible to provide a wide variety of shapes.

[0016] According to the present invention, by integrating a solar panel with a secondary battery connected to the solar panel, it becomes possible to supply the generated power obtained from the solar panel without loss via wireless power supply without using conductors, which is expected to reduce the burden of time and cost in terms of equipment required when introducing solar power generation.

[0017] In addition, the use of film solar panels has the advantage of being lightweight and easily bendable, making it possible to offer a wide variety of shapes, such as basic shapes such as triangles and hexagons, and three-dimensional honeycomb structures, and is expected to reduce the workload involved in assembling the solar panels.

[0018] Furthermore, using a capacitor battery as a secondary battery allows for large-capacity storage, and because there is almost no natural discharge, the amount of stored electricity does not decrease even after several years. Therefore, for example, when electricity is needed in the event of a disaster or emergency, the capacitor battery can be used as an emergency power source.

[0020] A direct solar panel storage battery according to one embodiment of the present invention will be described with reference to Fig. 1. Fig. 1 is a schematic diagram showing an example of the basic configuration (front cross-sectional view) of a direct solar panel storage battery according to an embodiment of the present invention.

[0021] As shown in Figure 1, the direct solar panel battery is formed by integrating a solar panel 11 with a secondary battery 12 electrically connected to the solar panel 11. Here, the solar panel 11 is, for example, a film-type solar panel or a perovskite solar panel, and the entire back surface of the solar panel 11 is directly connected to the secondary battery 12, thereby integrating power generation and storage into a unit.

[0022] The secondary battery 12 is formed as a capacitor device having a contact electrode portion disposed in contact with the rear surface of the solar panel 11 and an opposing electrode portion that forms a pair with the contact electrode portion.

[0023] Furthermore, the secondary battery 12 is formed as a thin plate on the backside of or inside the solar panel 11, and configured as a capacitor device. This is expected to have the effect of reducing the burden of time and cost in terms of equipment required when introducing solar power generation.

[0024] 1, the direct solar panel battery has heat-dissipating carbon 13 placed on the back surface of the secondary battery 12, and an induction antenna 15 sandwiched between an insulating film 14 and the back surface of the heat-dissipating carbon 13. Furthermore, by attaching an oscillator that generates an AC magnetic field for wireless power supply to the edge of the solar panel 11, it is possible to form a wireless power supply unit by electrically connecting this oscillator and induction antenna 15. This wireless power supply unit makes it possible to supply power generated by the solar panel via wireless power supply without using conductors.

[0025] Next, FIG. 2 is a schematic diagram showing an example of the configuration (front cross-sectional view) of a direct solar panel storage battery using a capacitor battery as a secondary battery.

[0026] As shown in Figure 2, the direct solar panel battery is formed by integrating a solar panel 11 with a capacitor battery electrically connected to the solar panel 11. For example, by directly connecting the entire back surface of the solar panel 11, such as a film solar panel or a perovskite solar panel, as a thin film capacitor (capacitor battery), power generation and storage are integrated into a unit.

[0027] The capacitor battery is configured as a capacitor device including a contact electrode portion 21 arranged in contact with the back surface of the solar panel 11, an opposing electrode portion 23 that pairs with the contact electrode portion 21, and a dielectric 22 formed so as to be sandwiched between the contact electrode portion 21 and the opposing electrode portion 23. Here, the contact electrode portion 21 and the opposing electrode portion 23 are formed from a conductive material, and are formed so as to store electrical energy in the dielectric 22.

[0028] Furthermore, the capacitor battery is configured as a capacitor device by being formed in the form of a thin plate on the backside or inside of the solar panel 11. This is expected to have the effect of reducing the burden of time and cost in terms of equipment required when introducing solar power generation.

[0029] The example shown in FIG. 1 is an example of a configuration diagram in which a plurality of capacitor devices are stacked in multiple layers and connected in parallel. By using such a configuration, it becomes possible to store a large amount of electrical energy between the electrodes, and a large-capacity capacitor device can be realized.

[0030] Next, Figure 3 is a schematic diagram showing an example of a shape using a film solar panel for a direct solar panel storage battery according to an embodiment of the present invention. Because film solar panels are lightweight and flexible, they can be provided in a variety of shapes, such as basic shapes such as triangles and hexagons, and three-dimensional honeycomb structures. In the example shown in Figure 3, the upper diagram shows a basic triangular shape, and the lower diagram shows a structure formed by connecting multiple units of the basic triangular shape shown in the upper diagram. By connecting multiple units in this way, a large-capacity capacitor device can be realized.

[0031] Next, FIG. 4 is a schematic diagram showing an example of a basic configuration diagram (oblique view) of a direct solar panel storage battery according to an embodiment of the present invention.

[0032] 4, the secondary batteries are formed with protruding connection electrodes that protrude from the edge of the solar panel 11 and fitting connection electrodes that fit into the protruding connection electrodes at the edge of the solar panel 11, and adjacent secondary batteries are electrically connected by fitting the protruding connection electrodes into the fitting connection electrodes. In this way, the solar panels 11 have a structure that is easy to connect like blocks, which makes it easier to arrange the solar panels 11 consecutively, reducing the burden of assembly work and enabling the realization of a large-capacity capacitor device.

[0033] Furthermore, when connecting multiple solar panels 11, there are two electrical connection methods: serial connection and parallel connection. In the case of a serial connection, the circuit is like connecting multiple capacitor batteries in series. In the case of a parallel connection, the circuit creates one large capacitor battery. For this reason, a battery management system was previously required to adjust the input and output power of each battery individually, but because the entire system is uniform, this is no longer necessary and all batteries are charged uniformly.

[0034] Next, FIG. 5 is a schematic diagram showing an example of a direct solar panel storage battery according to an embodiment of the present invention, in which a wireless power feeder for both power reception and power transmission is formed on the edge of the solar panel 11.

[0035] 5, a wireless power feeder can be formed by attaching an oscillator that generates an AC magnetic field for wireless power feeding to the edge of solar panel 11 and electrically connecting this oscillator to induction antenna 15. This wireless power feeder makes it possible to feed power generated by the solar panel wirelessly without using conductors.

[0036] Next, Figure 6 is a schematic diagram showing an example of assembling the solar panel 11 in the direct solar panel storage battery according to an embodiment of the present invention. The example shown in Figure 6 is an assembly example using a hexagonal film solar panel. As such, film solar panels are lightweight and flexible, so multiple panels can be connected to form a variety of shapes, and by connecting multiple panels to form a large-capacity capacitor device, it is possible to realize the large-capacity capacitor device.

[0037] Furthermore, direct solar panel batteries are lightweight and easy to assemble, so they have a wide range of uses, including the following potential applications:

[0038] <Application example> - By installing a direct solar panel storage battery on the roof of an agricultural greenhouse, electricity stored during the day can be used at night.

[0039] - By installing a direct solar panel battery on the upper back of the drone, it is possible to store electricity during flight and use that stored power to continue flying for long periods of time.

[0040] - By carrying a direct solar panel storage battery with you when you are doing outdoor activities such as hiking, you can use it as a mobile battery for your PC or other mobile devices.

[0041] ・Direct solar panel batteries can be stored as emergency power sources in disaster prevention warehouses, etc. By using a capacitor battery as a secondary battery, there is the advantage that the amount of stored electricity does not decrease even after several years because there is almost no natural discharge.In addition, in an emergency, the direct solar panel battery can be used to store electricity outdoors and use the stored electricity as an emergency power source.

[0042] - Depending on the design, the induction antenna for wireless power supply can be used as a heating wire for generating heat. Therefore, if this direct solar storage battery is installed on a roof in a snowy region, for example, it can be used as a snow melting device.
