[0030] As the global environment continues to deteriorate, countries are increasingly prioritizing clean energy. As a green, low-carbon energy source, clean energy is crucial for improving the energy mix, protecting the ecological environment, achieving sustainable economic and social development, and achieving carbon peak and carbon neutrality. Currently, there are many clean energy sources, such as solar and wind power. However, related technologies primarily rely on large enterprises to centrally deploy clean energy production equipment, collect, and utilize clean energy. For individual users, collecting and utilizing clean energy is difficult.

[0031] In view of this, in the embodiment of the present application, the charging cabinet 12 can accommodate both fully charged power banks 11 for user use and empty power banks 11 for the user to receive green energy. Furthermore, when the power bank 11 is received in the card slot 122, the power bank discharge element 112 establishes an electrical connection with the charging cabinet charging element 123, while the power bank charging element 111 also establishes an electrical connection with the charging cabinet discharge element 124. At this point, the charging cabinet battery 121 can charge the power bank 11 returned by the user (which can be an empty power bank 11 or a power bank 11 in an intermediate state) through the power bank charging element 111 and the charging cabinet discharge element 124, thereby maintaining the ratio of the various types of power banks 11 in the charging cabinet 12. The charging cabinet battery 121 can also discharge the fully charged power bank 11 returned by the user after receiving green energy through the power bank discharge element 112 and the charging cabinet charging element 123, transferring the green energy to the charging cabinet battery 121, thereby enabling individual users to collect, utilize, and store green energy.

[0032] Please refer to Figures 1 to 3 The present application provides an electric energy exchange system 1. Specifically, the electric energy exchange system 1 may include a charging cabinet 12 and a power bank 11. The power bank 11 may be borrowed by a user or stored in the charging cabinet 12.

[0033] The specific structure of the power exchange system 1 is described in detail below:

[0034] The power bank 11 includes one or more of a fully charged power bank 11, an empty power bank 11, and an intermediate state power bank 11. The empty power bank 11 is used to receive green electricity, and the fully charged power bank 11 is used to power user equipment. The power bank 11 is provided with a power bank charging element 111 and a power bank discharging element 112.

[0035] It is understood that a fully charged power bank 11 refers to a power bank 11 with sufficient charge. A power bank 11 with a charge exceeding a preset ratio (e.g., 95%) can be defined as a fully charged power bank 11. An empty power bank 11 refers to a power bank 11 with insufficient charge. A power bank 11 with a charge below a preset ratio (e.g., 5%) can be defined as an empty power bank 11. An intermediate power bank 11 refers to a power bank 11 with a charge between sufficient and insufficient. A power bank 11 with a charge within a preset ratio range (e.g., 5%-95%) can be defined as an intermediate power bank 11. Fully charged, empty, and intermediate states are different states of the power bank 11, and each power bank 11 is in one of these three states.

[0036] Specifically, the power bank charging element 111 is used to receive power from the charging cabinet battery 121, and can specifically be a charging interface, charging contacts, etc. The power bank discharging element 112 is used to provide power to the user device or the charging cabinet battery 121, and can specifically be a discharging interface.

[0037] The charging cabinet 12 includes a controller, a charging cabinet battery 121, a card slot 122, a charging cabinet charging element 123, and a charging cabinet discharging element 124. The charging cabinet battery 121 is electrically connected to the charging element and the discharging element, respectively. When the power bank 11 is stored in the card slot 122, the power bank discharging element 112 is electrically connected to the charging cabinet charging element 123, and the power bank charging element 111 is electrically connected to the charging cabinet discharging element 124. The controller is used to control the charging cabinet battery 121 to charge or discharge the power bank 11.

[0038] Specifically, the controller can be used to control the charging and discharging processes of the charging cabinet battery 121 and monitor the status of the power bank 11. It is located inside the charging cabinet 12. The charging cabinet battery 121 can store electrical energy as the system's energy reserve and is located inside the charging cabinet 12. The slot 122 is used to secure and connect the power bank 11, ensuring that it properly interfaces with the charging and discharging components of the charging cabinet 12. The slot 122 can be located outside or inside the charging cabinet 12 (if the charging cabinet 12 is designed to be retractable), making it easy for the user to insert and remove the power bank 11. The charging cabinet charging element 123 is used to charge the power bank 11 when the power bank 11 is low on charge. It can be located inside or near the slot 122 to ensure close contact with the power bank charging element 111. The charging cabinet discharging element 124 is used to receive electrical energy from the power bank 11 when the charging cabinet battery 121 needs to be replenished. It is also located inside or near the slot 122 and corresponds to the power bank discharging element 112.

[0039] When the power bank 11 is placed into the slot 122 of the charging cabinet 12, the charging cabinet charging element 123 inserts into the power bank discharging element 112, thereby establishing an electrical connection. Under the control of the controller, this allows the fully charged power bank 11 to discharge into the charging cabinet battery 121. Simultaneously, the charging cabinet discharging element 124 inserts into the power bank charging element 111, or the charging cabinet discharging element 124 abuts against the power bank charging element 111, thereby establishing an electrical connection. Under the control of the controller, this allows the charging cabinet battery 121 to charge the empty power bank 11 or the power bank 11 in an intermediate state.

[0040] The controller can control the charging cabinet battery 121 to charge or discharge the power bank 11 according to a pre-set control program.

[0041] The specific control method of the controller may be to first perform the following steps:

[0042] When receiving a borrowing request sent by a user terminal, parsing the target power bank 11 type corresponding to the borrowing request, the target power bank 11 type includes a fully charged power bank 11 and an empty power bank 11, and the empty power bank 11 is used to receive green electricity;

[0043] Determine the target power bank 11 based on the type of the target power bank 11;

[0044] The charging cabinet 12 is controlled to pop out the target power bank 11 .

[0045] Then perform the following steps:

[0046] Obtain the number of fully charged power banks 11, empty power banks 11, and empty card slots 122 in the charging cabinet 12;

[0047] Calculate the proportion of fully charged power banks 11, the proportion of empty power banks 11, and the proportion of empty card slots 122 respectively;

[0048] When the proportion of fully charged power banks 11 is lower than the first preset proportion, the number of power banks 11 to be charged that is required to make the proportion of fully charged power banks 11 reach the first preset proportion is calculated;

[0049] The charging cabinet 12 is controlled to charge the number of empty power banks 11 to be charged through the charging cabinet battery 121 .

[0050] Or perform the following steps:

[0051] When the proportion of empty power banks 11 is lower than the second preset proportion, the number of power banks 11 to be discharged that is required to make the proportion of empty power banks 11 reach the second preset proportion is calculated;

[0052] The charging cabinet 12 is controlled to discharge the fully charged power banks 11 to be discharged through the charging cabinet battery 121 .

[0053] The beneficial effects of the embodiments of the present application compared with the prior art are as follows: the embodiments of the present application include a charging cabinet 12 and a power bank 11, the power bank 11 includes one or more of a fully charged power bank 11, an empty power bank 11 and an intermediate state power bank 11, the empty power bank 11 is used to receive green electricity, the fully charged power bank 11 is used to power user equipment, the power bank 11 is provided with a power bank charging element 111 and a power bank discharging element 112, the charging cabinet 12 includes a controller, a charging cabinet battery 121, a card slot 122, a charging cabinet charging element 123, and a charging cabinet discharging element 124, the charging cabinet battery 121 is electrically connected to the charging element and the discharging element respectively, when the power bank 11 is stored in the card slot 122, the power bank discharging element 112 establishes an electrical connection with the charging cabinet charging element 123, and the power bank charging element 111 establishes an electrical connection with the charging cabinet discharging element 124, the controller is used to control the charging cabinet battery 121 to charge or discharge the power bank 11. In the embodiment of the present application, the charging cabinet 12 can contain both fully charged power banks 11 for user use and empty power banks 11 for users to receive green energy. When the power bank 11 is stored in the card slot 122, the power bank discharge element 112 establishes an electrical connection with the charging cabinet charging element 123. Simultaneously, the power bank charging element 111 establishes an electrical connection with the charging cabinet discharge element 124. At this point, the charging cabinet battery 121 can charge the power bank 11 returned by the user (which can be an empty power bank 11 or a power bank 11 in an intermediate state) through the power bank charging element 111 and the charging cabinet discharge element 124, thereby maintaining the ratio of the various types of power banks 11 in the charging cabinet 12. The charging cabinet battery 121 can also discharge the fully charged power bank 11 returned by the user after receiving green energy through the power bank discharge element 112 and the charging cabinet charging element 123, transferring the green energy to the charging cabinet battery 121, thereby enabling individual users to collect, utilize, and store green energy.

[0054] In a typical application scenario, a user can borrow an empty power bank 11 from a charging cabinet 12 and connect it to a green power generation device. The empty power bank 11 receives the electricity generated by the green power generation device and stores it in its own battery. When the battery is fully charged, the empty power bank 11 becomes a fully charged power bank 11. At this point, the user can remove the fully charged power bank 11 and return it to the charging cabinet 12 to receive a corresponding reward (e.g., the electricity fee corresponding to the amount of electricity in the fully charged power bank 11).

[0055] Based on this, Figure 4As shown, in some embodiments of the present application, the charging cabinet 12 includes a fully-charged power bank return button 125, which is electrically connected to the controller. The controller is configured to: when receiving the electrical signal sent by the fully-charged power bank return button 125, determine the target fully-charged power bank 11, and generate a first control instruction to control the charging cabinet 12 to open the card slot 122 corresponding to the target fully-charged power bank 11.

[0056] Specifically, the fully charged power bank return button 125 is a physical button or a touch button that can be installed on the outside or user interface of the charging cabinet 12. When the user presses the fully charged power bank return button 125, it indicates that the user wants to return the fully charged power bank 11. The fully charged power bank return button 125 is connected to the controller via wires or wireless signals. When the user presses the button, it sends an electrical signal to the controller. The controller can be connected to each card slot 122 in the charging cabinet 12 via wires or an internal communication bus. Therefore, when receiving the electrical signal sent by the fully charged power bank return button 125, the controller can determine the target fully charged power bank 11 according to a preset program and generate a first control instruction to control the charging cabinet 12 to open the card slot 122 corresponding to the target fully charged power bank 11. At this time, the user can put the fully charged power bank 11 into this card slot 122 to return the fully charged power bank 11.

[0057] The embodiment of the present application provides a fully-charged power bank return button 125 , allowing the user to more conveniently return the fully-charged power bank 11 to the charging cabinet 12 , thereby reducing the user's operation steps and improving the usability of the system.

[0058] like Figure 4 As shown, in some embodiments of the present application, the charging cabinet 12 includes an empty power bank return button 126, and the empty power bank return button 126 is electrically connected to the controller. The controller is configured to: when receiving the electrical signal sent by the empty power bank return button 126, determine the target empty power bank 11, and generate a second control instruction to control the charging cabinet 12 to open the card slot 122 corresponding to the target empty power bank 11.

[0059] Specifically, the empty power bank return button 126 is a physical or touch button provided on the charging cabinet 12, which is used to trigger the operation of returning the empty power bank 11. When the user wants to return a power bank 11 that has run out of power, the empty power bank return button 126 can be pressed. When the user presses the empty power bank return button 126, it sends an electrical signal to the controller. After the controller receives the electrical signal from the empty power bank return button 126, it can determine the target empty power bank 11 according to a preset program, and send a control instruction to the corresponding card slot 122 to open the corresponding card slot 122. At this time, the user can put the empty power bank 11 into this card slot 122 to return the empty power bank 11.

[0060] The embodiment of the present application provides an empty power bank return button 126 so that the user can more conveniently return the empty power bank 11 to the charging cabinet 12, thereby reducing the user's operation steps and improving the usability of the system.

[0061] like Figure 4 As shown, in some embodiments of the present application, the charging cabinet 12 includes a fully-charged power bank borrowing button 127, which is electrically connected to the controller. The controller is configured to: when receiving the electrical signal sent by the fully-charged power bank borrowing button 127, determine the target fully-charged power bank 11, and generate a third control instruction to control the card slot 122 corresponding to the target fully-charged power bank 11 to pop out the target fully-charged power bank 11.

[0062] Specifically, the fully-charged power bank borrowing button 127 can be located on the outside of the charging cabinet 12, making it easy for the user to click. Communication between the fully-charged power bank borrowing button 127 and the controller can be achieved via an electrical connection (e.g., wires, wireless signals, etc.). The controller can be connected to the card slot 122 via internal circuitry and mechanical structures (e.g., a motor or transmission) to control the ejection mechanism of the card slot 122. Upon receiving the electrical signal transmitted by the fully-charged power bank borrowing button 127, the controller can determine the target fully-charged power bank 11 and, according to a preset program, generate a third control instruction to control the card slot 122 corresponding to the target fully-charged power bank 11 to eject the target fully-charged power bank 11. The user can then remove the target fully-charged power bank 11 from the card slot 122, thereby borrowing the fully-charged power bank 11.

[0063] The embodiment of the present application allows borrowing a fully charged power bank 11 through simple button operation, thereby improving the usability of the system and user satisfaction.

[0064] In a typical application scenario, in order to store the electric energy generated by the green power generation equipment, the user can borrow the empty power bank 11 from the charging cabinet 12 and use the empty power bank 11 to store the green electric energy.

[0065] Based on this, Figure 4As shown, in some embodiments of the present application, the charging cabinet 12 includes an empty power bank borrowing button 128, and the empty power bank borrowing button 128 is electrically connected to the controller. The controller is configured to: when receiving the electrical signal sent by the empty power bank borrowing button 128, determine the target empty power bank 11, and generate a fourth control instruction to control the card slot 122 corresponding to the target empty power bank 11 to pop out the target empty power bank 11.

[0066] Specifically, the empty power bank borrowing button 128 can be located on the outside of the charging cabinet 12, making it easy for the user to click. Communication between the empty power bank borrowing button 128 and the controller can be achieved via an electrical connection (e.g., wires, wireless signals, etc.). The controller can be connected to the card slot 122 via internal circuitry and mechanical structures (e.g., a motor or transmission) to control the ejection mechanism of the card slot 122. Upon receiving the electrical signal transmitted by the empty power bank borrowing button 128, the controller can determine the target empty power bank 11 and, according to a preset program, generate a fourth control instruction to control the card slot 122 corresponding to the target empty power bank 11 to eject the target empty power bank 11. The user can then remove the target empty power bank 11 from the card slot 122, thereby borrowing the empty power bank 11.

[0067] The embodiment of the present application allows the user to conveniently borrow an empty power bank 11 to receive green electricity.

[0068] It can be understood that in other embodiments of the present application, the charging cabinet includes a power bank return button, which is electrically connected to the controller. The controller is configured to: when receiving the electrical signal sent by the power bank return button, determine the target power bank and generate a fifth control instruction to control the charging cabinet to open the card slot corresponding to the target power bank.

[0069] Specifically, the power bank return button can be located on the outside of the charging cabinet 12, making it easy for the user to click. Communication between the power bank return button and the controller can be achieved via an electrical connection (e.g., wires, wireless signals, etc.). The controller can be connected to the card slot 122 via internal circuitry and mechanical structures (e.g., motors and transmissions) to control the ejection mechanism of the card slot 122. Upon receiving the electrical signal from the power bank return button, the controller can determine the target power bank 11 according to a preset program and send a fifth control command to the corresponding card slot 122 to open the corresponding card slot 122. The user can then place any power bank 11 into this card slot 122 to return the power bank 11.

[0070] In some application scenarios, users can borrow fully charged power banks 11 or empty power banks 11 from the charging cabinet 12 at any time, and can also return fully charged power banks 11 or empty power banks 11 to the charging cabinet 12 at any time. When the number of power banks 11 returned by users is large, the charging cabinet 12 may not have empty card slots 122 to store the power banks 11 that need to be returned. In the usage scenarios corresponding to the embodiments of the present application, there is a need to reserve a certain number of empty card slots 122 to store the fully charged power banks 11 returned by users. In addition, in the usage scenarios corresponding to the embodiments of the present application, in order to better meet the different needs of users to borrow and return different types of power banks 11, there is also a need to adjust the corresponding ratios of fully charged power banks 11, empty power banks 11 and empty card slots 122 in the charging cabinet 12. When the ratio of empty card slots 122 in the charging cabinet 12 is unbalanced, it is necessary to adjust the number of various types of power banks 11 in the charging cabinet 12 so that the ratio of empty card slots 122 in the charging cabinet 12 reaches within a preset range.

[0071] Based on this, Figure 5 As shown, in some embodiments of the present application, the charging cabinet 12 includes a storage compartment 129 , and one or more receiving slots 1291 are provided in the storage compartment 129 , and the receiving slots 1291 are used to store the power bank 11 .

[0072] Specifically, the storage bin 129 is used to store various types of power banks 11, and one or more receiving slots 1291 are provided inside the storage bin 129. The shape, size and arrangement of these receiving slots 1291 correspond to the size and number of the power banks 11 to ensure that the power banks 11 can be placed therein securely while being convenient for users to take and put in. More specifically, the storage bin 129 is located inside the charging cabinet 12, and the receiving slots 1291 are provided inside the storage bin 129, and are integral with or detachable from the storage bin 129. When the user needs to adjust the proportion of empty card slots 122 in the charging cabinet 12, or when there are no empty card slots 122 in the charging cabinet 12, the user or maintenance personnel can place the extra power banks 11 in the charging cabinet 12 in the receiving slots 1291 to leave some empty card slots 122.

[0073] The embodiment of the present application provides a storage bin 129 and a receiving slot 1291 on the charging cabinet 12, which can facilitate the user to adjust the ratio of various types of power banks 11 and empty card slots 122 in the charging cabinet 12 at any time, thereby meeting the user's needs for borrowing and returning various types of power banks 11.

[0074] When a user returns a large number of fully charged power banks 11 to the charging cabinet 12, the controller will transfer the power of some fully charged power banks 11 to the charging cabinet battery 121 via the power bank discharge element 112 and the charging cabinet charging element 123 in order to maintain the ratio of the various types of power banks 11 in the charging cabinet 12 and meet the different needs of users. In some typical usage scenarios, when the power of the charging cabinet battery 121 reaches a certain ratio or is full, it is difficult to continue transferring the power of the fully charged power banks 11 to the charging cabinet battery 121 via the power bank discharge element 112 and the charging cabinet charging element 123. In this case, it is impossible to dynamically adjust the ratio of the various types of power banks 11 in the charging cabinet 12 by discharging the fully charged power banks 11.

[0075] Based on this, in some embodiments of the present application, the power exchange system 1 also includes a backup battery, which is electrically connected to the charging cabinet battery 121, and the controller is also used to control the charging cabinet battery 121 to charge or discharge the backup battery.

[0076] Specifically, the backup battery is used to adjust the charge level of the charging cabinet battery 121. Specifically, it can reduce the charge level of the charging cabinet battery 121 by receiving electrical energy from the charging cabinet battery 121. Alternatively, it can increase the charge level of the charging cabinet battery 121 by transmitting electrical energy to the charging cabinet battery 121. The backup battery and the charging cabinet battery 121 can be connected via some form of electrical connection (such as a cable, circuit board, etc.) to allow for the transmission of electrical energy. An electrical connection also exists between the controller and the two batteries, which can be achieved through an electrical circuit or communication line. This connection allows the controller to read the battery status (such as charge level, voltage, etc.) and send control signals (such as charge and discharge commands) as needed, thereby controlling the charging cabinet battery 121 to charge or discharge the backup battery, thereby dynamically adjusting the charge level of the charging cabinet battery 121.

[0077] The embodiment of the present application is provided with a backup battery electrically connected to the charging cabinet battery 121. Under the control of the controller, the backup battery can be used to dynamically adjust the power of the charging cabinet battery 121 to meet various needs of users.

[0078] In some typical green electricity application scenarios, users can upload the power in the battery to the power grid to obtain electricity charges corresponding to the uploaded power. Based on this, in some specific embodiments of the present application, the power exchange system 1 also includes an inverter, which is electrically connected to the backup battery and is used to upload the power from the backup battery to the power grid.

[0079] Specifically, an inverter is a power electronic device whose function is to convert direct current (DC) into alternating current (AC), or vice versa. In the embodiment of the present application, the main function of the inverter is to convert the DC power in the backup battery into AC power suitable for use in the power grid. The inverter is usually located at the interface between the backup battery and the power grid and is responsible for the conversion and transmission of power. The inverter can be connected to the backup battery through an electrical connection (such as a cable) to obtain DC power from the battery. The inverter is also connected to the power grid through another set of electrical connections to upload the converted AC power to the power grid.

[0080] By introducing a backup battery and inverter, the present embodiment enables the power exchange system 1 to convert the battery's electrical energy into AC power via the inverter and upload it to the power grid. This allows for the storage of excess electrical energy during off-peak hours and its release when needed, thereby improving energy efficiency. Users can also receive corresponding rewards by uploading green electricity. Furthermore, this further enables the utilization and storage of green energy, contributing to the development and application of green energy.

[0081] In some specific embodiments of the present application, the power exchange system 1 also includes a green power generation device, which is used to generate green power. The green power generation device includes a discharge interface, and the power bank 11 includes a charging interface. When the charging interface is electrically connected to the discharge interface, the power bank 11 receives the green power generated by the green power generation device.

[0082] Specifically, green power generation equipment can generate green electricity using renewable energy sources (such as solar, wind, and hydropower). Green power generation equipment is typically located in the power generation portion of a system and may include solar panels, wind turbines, small hydropower stations, and other components. It can reduce reliance on fossil fuels and greenhouse gas emissions. The discharge interface is a key component of a green power generation device, responsible for outputting the generated green electricity to an external device or system. The discharge interface can be designed as a standard interface to facilitate connection with other devices or systems (such as a power bank 11). The charging interface is a key component of the power bank 11, responsible for receiving electricity from an external device or system (such as a green power generation device). The charging interface is typically compatible with the discharge interface to facilitate power transmission. When the green electricity generated by the green power generation device needs to be stored in the power bank 11, the discharge interface and the charging interface are electrically connected, allowing the green electricity to be transferred from the green power generation device to the power bank 11 and stored in the power bank 11's battery.

[0083] By introducing a combination of green power generation equipment and a power bank 11, the embodiment of the present application enables the power exchange system 1 to better utilize renewable energy to generate green electricity and store it in the power bank 11 for subsequent use, thereby helping to expand the coverage of green electricity and improve its utilization rate.

[0084] In some specific embodiments of the present application, the power bank charging component 111 and the power bank discharging component 112 are both arranged on the bottom surface of the power bank 11, and the charging cabinet charging component 123 and the charging cabinet discharging component 124 are both arranged on the front of the card slot 122. When the power bank 11 is stored in the card slot 122, the bottom surface of the power bank 11 abuts against the front of the card slot 122.

[0085] Specifically, when the power bank 11 is stored in the card slot 122 of the charging cabinet 12, the bottom surface of the power bank 11 abuts the front surface of the card slot 122. This allows the power bank charging element 111 and the power bank discharge element 112 to be aligned and in contact with the charging cabinet charging element 123 and the charging cabinet discharge element 124, respectively. Through physical contact, an electrical connection can be established between the power bank charging element 111 and the charging cabinet discharge element 124. This connection allows electrical energy to be transferred from the charging cabinet 12 to the power bank 11 to charge it. Similarly, through physical contact, the power bank discharge element 112 is aligned and in contact with the charging cabinet charging element 123, at which point electrical energy can be released from the power bank 11 to the charging cabinet 12 or other devices.

[0086] In this embodiment, the charging and discharging components of the power bank 11 are located on the bottom surface, and the charging component of the charging cabinet 12 is located on the front of the card slot 122, which simplifies the user operation process. The user only needs to place the power bank 11 into the card slot 122, and the electrical connection is automatically established without any additional operation or adjustment.

[0087] The above description is merely an optional embodiment of the present application and does not limit the patent scope of the present application. All equivalent structural transformations made using the contents of the present application specification and drawings under the inventive concept of the present application, or direct / indirect application in other related technical fields are included in the patent protection scope of the present application.
