The present invention relates to a battery device, in particular to a photovoltaic panel battery box used in low power consumption equipment and capable of generating electricity by light.

With the development of Internet of Things technology, many office machines and home appliances have networking functions. In order to connect the aforementioned office machines and home appliances to the Internet for management and control, many IoT node devices are usually installed in offices and homes to connect the aforementioned office machines and home appliances. At present, when these IoT node devices are installed, they are usually installed near the mains socket where electricity is easily accessible, or a power cord for connecting to the mains must be laid separately, so there are still inconveniences in installation. In addition, some devices are driven by disposable batteries. In addition to the inconvenience of frequent battery replacement, such devices also generate waste batteries, which is less environmentally friendly.

Energy conservation and carbon reduction are currently the environmental protection policies that the world is committed to promoting. Since offices and homes are usually equipped with electric lights or sunlight can shine into the room, and the aforementioned IoT node devices are usually low-power devices, if indoor light energy can be converted into electricity to drive the aforementioned IoT node devices, it will help achieve energy conservation and carbon reduction needs.

Therefore, the purpose of the present invention is to provide a photovoltaic panel battery box kit that can be used for low-power consumption equipment.

Therefore, the photovoltaic panel battery box set for low-power consumption equipment of the present invention includes at least one photovoltaic panel battery box. The at least one photovoltaic panel battery box includes a shell structure, and a power generation module and a power supply control module which are electrically connected and installed on the shell structure.

The power generation module includes a photovoltaic panel unit that can generate electricity by light, and a battery unit for storing the electricity generated by the photovoltaic panel unit. The power supply control module includes at least one parallel connector, a power supply connector, and a power supply control unit. The at least one parallel connector can connect the battery unit in parallel with the battery unit of another photovoltaic panel battery box when it is electrically connected to the photovoltaic panel battery box. The power supply control unit will be triggered when the power supply connector is electrically connected to the low-power consumption device, and control the battery unit to supply power to the low-power consumption device through the power supply connector.

The effect of the present invention is that through the structural design of the power generation module and the power supply control module of the photovoltaic panel battery box, the low-power consumption device can be driven by ambient light power generation, so that the installation location of the low-power consumption device is no longer limited to the vicinity of the mains socket or the need to lay a power extension line.

Referring to Figures 1, 2, and 3, an embodiment of the photovoltaic panel battery box set 100 of the present invention for low-power consumption equipment 900 is suitable for electrical connection and installation of the low-power consumption equipment 900. The low-power consumption equipment 900 is, for example but not limited to, an IOT node device, and the low-power consumption equipment 900 can be a device driven by traditional mains electricity or a device driven by a disposable battery. The photovoltaic panel battery box set 100 includes two photovoltaic panel battery boxes 2, an electrical connection line 6 connecting the photovoltaic panel battery boxes 2 in parallel, a bracket mechanism 7 installed on one of the photovoltaic panel battery boxes 2 and used to fix on a wall, and a connecting mechanism 8 connecting the photovoltaic panel battery boxes 2 together.

The electrical connection line 6 has two electrical connection ends 61 which are detachably and electrically connected to the photovoltaic panel battery boxes 2 respectively.

Since the photovoltaic panel battery boxes 2 have the same structure, for the convenience of description, the structure of one of the photovoltaic panel battery boxes 2 is first described as an example.

The photovoltaic panel battery box 2 includes a housing structure 3, and a power generation module 4 and a power supply control module 5 which are electrically connected and mounted on the housing structure 3.

The housing mechanism 3 includes a housing body 31 for mounting the power generation module 4 and the power supply control module 5, and a plurality of connecting parts 32 and a plurality of equipment mounting parts 33 disposed at intervals on the back of the housing body 31. In this embodiment, the connecting parts 32 and the equipment mounting parts 33 are both nuts fixedly embedded in the housing body 31, but the implementation is not limited thereto.

Referring to Figs. 1, 2, and 4, the power generation module 4 includes a photovoltaic panel unit 41 mounted and exposed on the front side of the housing body 31, a battery unit 42 electrically connected to the photovoltaic panel unit 41, and a protection unit 43 electrically connected between the photovoltaic panel unit 41 and the battery unit 42. The photovoltaic panel unit 41 can generate electricity by light, and the battery unit 42 can store the electricity generated by the photovoltaic panel unit 41. The photovoltaic panel unit 41 can be, for example but not limited to, a silicon solar panel or a dye-sensitized solar cell (DSSC). Since the photovoltaic panel unit 41 can generate electricity by light, and the battery unit 42 can be used to store electricity, both are existing technologies and have many forms, and therefore will not be described in detail.

The protection unit 43 can prevent the battery unit 42 from reversely supplying power to the photovoltaic panel unit 41, thereby preventing the photovoltaic panel unit 41 from malfunctioning and becoming a power-consuming component. In this embodiment, the protection unit 43 is a reverse current protection circuit composed of a diode, but because the protection unit 43 is a prior art and has many types, it will not be described in detail.

In practice, the voltage measuring unit 55, the capacitance measuring unit 56, the power generation measuring unit 57 and the power supply control unit 58 can be integrated together.

The parallel connectors 51 are electrically connected to the photovoltaic panel unit 41 and the battery unit 42. Each of the parallel connectors 51 can be electrically connected and plugged into one of the electrical connection ends 61 of the electrical connection line 6. When the electrical connection line 6 is electrically connected to two of the parallel connectors 51 of the photovoltaic panel battery boxes 2 with the electrical connection ends 61, the battery units 42 of the photovoltaic panel battery boxes 2 are connected in parallel via the electrical connection line 6, and the photovoltaic panel units 41 of the photovoltaic panel battery boxes 2 are connected in parallel via the electrical connection line 6. In the present embodiment, the parallel connectors 51 and the electrical connection ends 61 of the electrical connection line 6 are designed with a USB port interface that can correspond to electrical connection plugging, but the implementation is not limited thereto.

The power supply connector 52 can be used for the low-power device 900 to be electrically connected and installed via a power cord 901, and can be used to output the power required for the operation of the low-power device 900. In this embodiment, the power supply connector 52 is also designed as a USB port interface, but the implementation is not limited to this.

The warning unit 53 is a display embedded and exposed on the front side of the housing body 31, which can be driven to send out warning messages in the form of images. However, in practice, in other embodiments of the present invention, the warning unit 53 can also be changed to a type that can send out warning messages of sound or light, or a type that can send out a warning message of any combination of the above three warning messages, or a type that can send out a signal that can be wirelessly received by other devices.

The photosensitive unit 54 can be activated by the power supply control unit 58 to sense the light intensity on the front side of the housing body 31. In this embodiment, the photosensitive unit 54 senses light through photoresistance technology, but because there are many types of sensors that can sense the light intensity, they will not be described in detail, and the implementation is not limited to the above-mentioned state.

The voltage measuring unit 55 can be controlled to start by the power supply control unit 58 to measure the battery voltage of the battery cell 42. However, when the electrical connection line 6 connects the battery cells 42 in parallel, the voltage measuring unit 55 will measure the battery voltage of the battery cells 42 connected in parallel.

The capacitance measuring unit 56 can be activated by the power supply control unit 58 to measure the battery capacity of the battery cell 42. However, when the electrical connection line 6 connects the battery cells 42 in parallel, the capacitance measuring unit 56 measures the total battery capacity of the battery cells 42 connected in parallel.

The power generation measurement unit 57 can be controlled and started by the power supply control unit 58 to measure the power generation of the photovoltaic panel unit 41. However, when the electrical connection line 6 is connected in parallel to the photovoltaic panel units 41, the power generation measurement unit 57 will measure the power generation of the photovoltaic panel units 41 connected in parallel.

The power supply control unit 58 is signal-connected to the warning unit 53, the photosensitive unit 54, the voltage measuring unit 55, the capacitance measuring unit 56, the power generation measuring unit 57 and the power supply connector 52. The power supply control unit 58 has a built-in master mode and a slave mode that can be switched to start. When the power supply control unit 58 is switched to the slave mode, the photosensitive unit 54, the voltage measuring unit 55, the capacitance measuring unit 56 and the power generation measuring unit 57 will not be controlled to start. When the power supply control unit 58 detects that the power supply connector 52 is electrically connected to the low-power consumption device 900, it switches from the default slave mode to the master mode, and controls the battery unit 42 to supply power to the low-power consumption device 900 via the power supply connector 52, and also controls the activation of the photosensitive unit 54, the voltage measuring unit 55, the capacitance measuring unit 56 and the power generation measuring unit 57.

When the power supply control unit 58 switches to the master control mode, it receives and analyzes the light intensity measured by the photosensitive unit 54, the battery voltage measured by the voltage measuring unit 55, the battery capacity measured by the capacity measuring unit 56, and the power generation measured by the power generation measuring unit 57. When the power supply control unit 58 determines that the light intensity is less than a predetermined light intensity value, it drives the warning unit 53 to issue a warning message representing low illumination. When the power supply control unit 58 analyzes and determines that the battery voltage is less than a predetermined voltage value, it controls the warning unit 53 to issue a warning message representing that the battery voltage is too low.

When the power supply control unit 58 switches to the master control mode, it will also start an energy consumption analysis function, and will continuously receive and analyze the battery capacity measured by the capacity measurement unit 56 within a predetermined time, such as but not limited to 8 hours, 12 hours or 24 hours. When the power supply control unit 58 analyzes and determines that the battery capacity has not been charged to a predetermined capacity value within the predetermined time, it will control the warning unit 53 to issue a warning message representing insufficient power generation.

When the power supply control unit 58 controls the warning unit 53 to send out the warning message indicating that the battery capacity is insufficient, it will further analyze the change of the battery capacity within the predetermined time and obtain the total power consumption of the low-power consumption device 900 within the predetermined time. The power supply control unit 58 will also statistically obtain the power generation measured by the power generation measurement unit 57 at the predetermined time to obtain the total power generation of the photovoltaic panel unit 41 at the predetermined time. Then, the power supply control unit 58 will analyze and calculate the total power consumption and the total power generation according to the preset analysis program to obtain a photovoltaic panel battery box parallel demand, and send out a warning message corresponding to the photovoltaic panel battery box parallel demand through the warning unit 53.

Referring to Figs. 1, 2, and 3, the bracket mechanism 7 includes a universal joint 71 detachably mounted on one of the connecting members 32 of one of the housing bodies 31, and a fixing seat 72 mounted on the universal joint 71 to be rotatably adjusted relative to the angle and to be fixed on the wall. In this embodiment, since the connecting members 32 are nut studs, the universal joint 71 is fixed to the corresponding connecting member 32 by screwing.

The connecting mechanism 8 includes two plate-shaped jumpers 81 extending and spanning between the shell bodies 31 at intervals, and a plurality of equipment fixing members 82 respectively penetrating the two ends of the jumpers 81 and respectively screwed to the connecting members 32 of the shell bodies 31. The equipment fixing members 82 will lock and fix the jumpers 81 to the shell bodies 31, so that the photovoltaic panel battery boxes 2 are firmly connected together. In this embodiment, the shell bodies 31 are connected together up and down, but in practice, in other embodiments of the present invention, the shell bodies 31 can also be connected together left and right.

1, 2, and 4, when the photovoltaic panel battery box kit 100 of the present invention is used for the low-power consumption device 900, the shell mechanisms 3 can be connected together through the connecting mechanism 8, and the bracket mechanism 7 can be installed and fixed to the shell mechanism 3 of one of the photovoltaic panel battery boxes 2, and the low-power consumption device 900 can be locked and fixed to the device fixing parts 82 of one of the shell mechanisms 3 through bolts, and installed and fixed to the rear side of the shell mechanism 3.

Next, the electrical connection line 6 is electrically connected and inserted into two of the parallel connectors 51 of the photovoltaic panel battery boxes 2 to connect the photovoltaic panel battery boxes 2 in parallel. Then, the power line 901 of the low-power consumption device 900 is electrically connected and inserted into the power supply connector 52 of one of the photovoltaic panel battery boxes 2.

When the photovoltaic panel battery box set 100 is installed and used for the low-power consumption device 900, the photovoltaic panel units 41 of the photovoltaic panel battery boxes 2 will be sensitive to light and generate electricity, and the generated electricity will be stored in the battery units 42.

After the photovoltaic panel battery box 2 selected to start the master control mode is electrically connected to the low-power consumption device 900, the power supply control unit 58 of the photovoltaic panel battery box 2 will switch to the master control mode, thereby starting the energy consumption analysis function, and controlling the battery unit 42 to supply power to the low-power consumption device 900 through the power supply connector 52, and controlling the activation of the photosensitive unit 54 and the voltage measurement unit 58 of the photovoltaic panel battery box 2. 5. The capacitance measuring unit 56 and the power generation measuring unit 57 start to receive and analyze the illuminance, the battery voltage, the battery capacity and the power generation, and when it is determined that the illuminance is lower than the predetermined illuminance value, the battery voltage is lower than the predetermined voltage value, or the battery capacity is not increased to the predetermined capacity value within the predetermined time, the warning unit 53 is controlled to send a corresponding warning message. When it is determined that the battery capacity is insufficient, the photovoltaic panel battery box parallel demand is obtained by analysis and calculation, and the warning unit 53 is driven to send a corresponding warning message.

The photovoltaic panel battery box set 100 can be used to install the low-power consumption device 900, and the structure design of being able to generate electricity by light can be conveniently installed in any place with light.

It must be explained that each photovoltaic panel battery box 2 of the photovoltaic panel battery box set 100 of the present invention can be used independently. When a single photovoltaic panel battery box 2 is used for installation and use of the low-power consumption device 900, the power supply control unit 58 of the power supply control module 5 will also be triggered to switch to the main control mode, and start the energy consumption analysis function, and can be used to warn of low light, low battery voltage and insufficient battery capacity, and will also analyze and obtain the parallel demand of the photovoltaic panel battery box. When other photovoltaic panel battery boxes 2 need to be connected in parallel, they are connected in parallel through the connecting mechanism 8 and connected in parallel through the electrical connection line 6, and then assembled into the photovoltaic panel battery box set 100.

Furthermore, in this embodiment, two photovoltaic panel battery boxes 2 are connected in parallel as an example for explanation, but in practice, the number of the photovoltaic panel battery boxes 2 can be increased, and the number of the connecting mechanisms 8 and the electrical connection lines 6 can be increased accordingly.

In summary, through the structural design of the power generation module 4 and the power supply control module 5 of each photovoltaic panel battery box 2, it is convenient to increase the power generation and battery capacity by connecting multiple photovoltaic panel battery boxes 2 in parallel, and the installation location of the low-power consumption device 900 is no longer limited to the vicinity of the mains socket or the need to install a power extension line. In addition, each photovoltaic panel battery box 2 can also be used to supply power to the low-power consumption device 900 that uses disposable batteries, thereby eliminating the use of disposable batteries and being more environmentally friendly. Therefore, the photovoltaic panel battery box set 100 for low-power consumption devices 900 of the present invention is indeed a very innovative and convenient and practical creation, and can indeed achieve the purpose of the present invention.
