[0029] In order to make the objectives, technical solutions and advantages of the present application clearer, further detailed description will be made to the present application with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application, and are not used to limit the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative work belong to the protection scope of the present application.

For example, the process, method, terminal, product or device including a series of steps or units is not limited to the listed steps or units, but can optionally further include the steps or units not listed, or can optionally further include other steps or units inherent to the process, method, product or device.

[0031] Reference to“an embodiment” herein means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the application. The appearances of the phrase“in an embodiment” in various places in the specification are not necessarily all referring to the same embodiment, nor are they necessarily mutually exclusive of one another. It is expressly understood that any of the embodiments described herein can be incorporated into other embodiments.

[0032] With the continuous deterioration of the earth's environment, countries are increasingly attaching importance to clean energy. As a green and low-carbon energy, clean energy is of great significance to improving the energy structure, protecting the ecological environment, realizing the sustainable development of the economy and society, and achieving carbon peak and carbon neutral. At present, there are various clean energies, such as solar energy, wind energy, etc. However, in the related technology, large enterprises mainly arrange clean energy production equipment, collect clean energy and utilize it. For individual users or small enterprises, it is difficult to collect and utilize clean energy.

[0033] Therefore, in the embodiments of the present application, when the user borrows a full-power power bank, the user can use the full-power power bank to meet the immediate power demand. When the user borrows an empty power bank, the empty power bank can be connected to a green power generation device to store green power, such as solar energy, wind energy, etc. The stored green power can not only meet the immediate power demand of the user, but also can be used for green power trading and other operations, realizing the collection and utilization of clean energy by individual users or small enterprises.

[0034] In order to illustrate the technical solutions of the present application, the following will be described by specific embodiments.

[0035] Figure 1 An implementation flowchart of an electric energy exchange method provided by an embodiment of the present application is shown, which can be applied to an intelligent charging cabinet in an electric energy exchange system. The electric energy exchange system can also include a power bank, which can be a full-power power bank, an empty power bank, an intermediate state power bank, etc. These power banks can be placed in the charging cabinet or borrowed by users.

[0036] A full-power power bank refers to a power bank with sufficient power, which can be defined as a power bank with power exceeding a preset proportion (e.g. 95%). An empty power bank refers to a power bank with insufficient power, which can be defined as a power bank with power lower than a preset proportion (e.g. 5%). An intermediate state power bank refers to a power bank with power between sufficient and insufficient, which can be defined as a power bank with power in a preset proportion interval (e.g. 5%-95%).

[0037] Specifically, the above-mentioned electric energy exchange method can include the following steps S101-S103.

[0038] Step S101, when receiving the borrowing request sent by the user terminal, the target power bank type corresponding to the borrowing request is parsed.

[0039] The target power bank type includes a full-power power bank and an empty-power power bank, and the empty-power power bank is used to receive green power.

[0040] In the embodiments of the present application, the user can select a borrowed power bank through a user terminal (such as a mobile phone APP) and specify the required power bank type (full power or empty power). The user terminal can generate a corresponding borrowing request and send it to the terminal device. After receiving the borrowing request, the terminal device can perform preliminary verification, such as checking the user account status, location information, etc., and analyzing the user request to determine whether the user wants to borrow a full-power power bank for use or an empty-power power bank to receive green power (for example, the user's home is equipped with a solar panel, and wants to store excess power in the power bank)

[0041] Step S102, determining the target power bank based on the target power bank type.

[0042] In the embodiments of the present application, the terminal device can search for a power bank that meets the user's needs in the charging cabinet according to the parsing result. If the target power bank is a full-power power bank, the terminal device can select a power bank with a power exceeding a preset proportion (for example, 95%) as the target power bank. If the target power bank is an empty-power power bank, the terminal device can select a power bank with a power lower than a preset proportion (for example, 5%) as the target power bank.

[0043] Step S103, controlling the charging cabinet to eject the target power bank.

[0044] In the embodiments of the present application, after the target power bank is determined, the terminal device can obtain the relative position of the target power bank in the charging cabinet and generate a corresponding instruction to control the charging cabinet to open the corresponding storage position and eject the target power bank.

[0045] The user can take out the ejected power bank, which can be directly used if it is a full-power power bank, or taken back home or enterprise and connected to a green energy power generation device (such as a solar panel) through a suitable interface to start charging the empty-power power bank, so as to meet the user's immediate power demand or conduct green power transaction, etc., thereby realizing power exchange.

[0046] The embodiments of the present application can realize that individual users and small enterprises directly participate in the collection and utilization of clean energy, significantly improving the popularity and utilization rate of clean energy. Users can flexibly choose to borrow full-power or empty-power power banks according to their own needs, which not only meets the immediate power demand, but also provides convenience for the storage and use of green power.

[0047] Compared with the prior art, the embodiment of the present application has the beneficial effects that: when the user terminal sends a borrowing request, the embodiment of the present application parses the target power bank type corresponding to the borrowing request, determines the target power bank based on the target power bank type, and controls the charging cabinet to pop out the target power bank. The embodiment of the present application controls the charging cabinet to pop out the corresponding target power bank by parsing the user's borrowing request. When the user borrows a full-power power bank, the user can use the full-power power bank to meet the immediate power demand. When the user borrows an empty-power power bank, the empty-power power bank can be connected to a green power generation device to store green power, such as solar energy, wind energy, etc. The stored green power can meet the user's immediate power demand and can also be used for green power trading and other operations, realizing the collection and utilization of clean energy by individual users or small enterprises.

[0048] As shown in Figure 4 In some embodiments of the present application, after the target power bank is popped out by the charging cabinet, the above method can further include steps S401 to S404.

[0049] Step S401, the number of full-power power banks, empty-power power banks and empty card slots in the charging cabinet is obtained.

[0050] The empty card slot is a card slot in the charging cabinet without a power bank.

[0051] In the embodiments of the present application, the terminal device can obtain the number of full-power power banks, empty-power power banks and empty card slots in the charging cabinet in real time through the built-in sensor or management system of the charging cabinet. Specifically, the terminal device can detect the power of each power bank in the charging cabinet to determine the number of full-power power banks and empty-power power banks. The number of empty card slots can also be determined by a pressure sensor.

[0052] Step S402, the full-power power bank proportion, the empty-power power bank proportion and the empty card slot proportion are calculated respectively.

[0053] In the embodiments of the present application, after obtaining the number of full-power power banks, empty-power power banks and empty card slots, the terminal device can calculate the full-power power bank proportion, the empty-power power bank proportion and the empty card slot proportion respectively according to the obtained number, so as to evaluate the distribution of power banks in the charging cabinet and determine whether adjustment is needed.

[0054] Step S403, when the full-power power bank proportion is lower than the first preset proportion, the number of power banks to be charged to make the full-power power bank proportion reach the first preset proportion is calculated.

[0055] It's understandable that the number of different types of power banks in the charging cabinet changes dynamically. When a user takes a fully charged power bank, the percentage of fully charged power banks decreases. If the percentage of fully charged power banks is very low, users may not be able to borrow one, impacting the user experience.

[0056] In the embodiments of this application, after obtaining the percentage of fully charged power banks, the terminal device can compare the percentage of fully charged power banks with a first preset ratio to determine whether the current number of fully charged power banks meets the preset threshold requirement. When the percentage of fully charged power banks is lower than the first preset ratio (e.g., 40%), the terminal device can calculate the number of empty power banks that need to be charged based on the current number of fully charged and empty power banks and the first preset ratio.

[0057] Step S404: Control the charging cabinet to charge the number of empty power banks to be charged through the charging cabinet's battery.

[0058] In the embodiments of this application, after determining the number of power banks to be charged, the terminal device can control the charging cabinet battery to charge the corresponding number of empty power banks, so as to ensure that there are enough fully charged power banks in the charging cabinet for users to borrow.

[0059] This application's implementation method ensures a sufficient number of fully charged power banks in the charging cabinet by real-time monitoring and adjustment of the proportion of each type of power bank, thereby improving the cabinet's utilization efficiency and user satisfaction. It also dynamically adjusts the charging and distribution of power banks according to actual needs, avoiding resource waste and idleness.

[0060] like Figure 5 As shown, in some specific embodiments of this application, after calculating the percentage of fully charged power banks, the percentage of empty power banks, and the percentage of empty card slots respectively, the above method may also include steps S501 and S502.

[0061] Step S501: When the percentage of empty power banks is lower than the second preset percentage, calculate the number of power banks to be discharged that will bring the percentage of empty power banks to the second preset percentage.

[0062] In the embodiments of this application, the terminal device can compare the calculated percentage of empty power banks with a second preset percentage (e.g., 20%) to determine whether the current number of empty power banks is lower than a preset threshold. When the percentage of empty power banks is lower than the second preset percentage, the terminal device can calculate the number of fully charged power banks that need to be discharged based on the current number of empty power banks, the total number of power banks, and the second preset percentage.

[0063] For example, assuming that there are 100 power banks in the charging cabinet, and there are 10 empty power banks at present, the empty power bank proportion is 10%. If the second preset proportion is 20%, it is expected that the number of empty power banks reaches 20. Therefore, the number of full power banks that need to be discharged is: 20 (expected number of empty power banks) - 10 (current number of empty power banks) = 10.

[0064] In step S502, the charging cabinet is controlled to discharge the full power banks of the number of power banks to be discharged by the charging cabinet battery.

[0065] In the embodiments of the present application, the terminal device can control the charging cabinet battery to discharge the corresponding number of full power banks according to the calculated number of power banks to be discharged, until they become empty power banks, thereby increasing the number of empty power banks to ensure that there are enough power banks to receive and store green power.

[0066] The embodiments of the present application improve the utilization rate and storage efficiency of green power by ensuring that there are enough empty power banks to receive green power. In addition, the management and resource allocation of the charging cabinet are also optimized by dynamically adjusting the state of the power banks.

[0067] As shown in Figure 6 In some specific embodiments of the present application, after calculating the full power bank proportion, the empty power bank proportion, and the empty slot proportion, respectively, the above method can further include steps S601 to S606.

[0068] In step S601, when the empty slot proportion is lower than the third preset proportion, the number of empty slots required to reach the third preset proportion is calculated.

[0069] In the embodiments of the present application, the terminal device can compare the calculated empty slot proportion with the third preset proportion (for example, 20%) to determine whether the current number of empty slots is lower than the preset threshold value and whether measures need to be taken to increase the number of empty slots. When the empty slot proportion is lower than the third preset proportion, the terminal device can calculate the number of slots that need to be emptied (i.e., the number of empty slots) according to the current number of empty slots, the total number of slots, and the third preset proportion.

[0070] For example, assuming that there are 100 slots in the charging cabinet, and there are 90 used slots at present, the empty slot proportion is 10%. If the third preset proportion is 20%, it is expected that the number of empty slots reaches 20. Therefore, the number of slots that need to be emptied is: 100 (total number of slots) * 20% (third preset proportion) - 10 (current number of empty slots) = 10.

[0071] In step S602, the number of intermediate state power banks in the charging cabinet is obtained.

[0072] Among them, the intermediate state power bank is the power bank that is neither fully charged nor empty.

[0073] In an embodiment of this application, the terminal device can detect the power level of all power banks in the charging cabinet to determine the number of power banks in the intermediate state.

[0074] Step S603: Compare the number of card slots to be emptied with the number of power banks in the intermediate state.

[0075] In the embodiments of this application, the terminal device can compare the calculated number of card slots to be emptied with the number of intermediate state power banks to determine whether there are enough intermediate state power banks that can be removed to increase the number of empty card slots.

[0076] Step S604: If the number of power banks in the intermediate state is greater than or equal to the number of card slots to be emptied, then determine the corresponding number of power banks to be taken away from the power banks in the intermediate state according to the number of card slots to be emptied.

[0077] In the embodiments of this application, if the number of power banks in the intermediate state is greater than or equal to the number of card slots to be emptied, the terminal device can determine the corresponding number of power banks to be taken away from the power banks in the intermediate state based on the number of card slots to be emptied, so as to increase the number of empty card slots.

[0078] Step S605: Obtain information about the power bank to be taken and the charging cabinet.

[0079] In the embodiments of this application, the terminal device can obtain detailed information about the power bank to be taken and the charging cabinet through the control system or database of the charging cabinet, thereby providing the necessary data support for generating notification information.

[0080] Step S606: Generate notification information based on the power bank information and charging cabinet information, and send the notification information to the maintenance user terminal.

[0081] In the embodiments of this application, the terminal device can generate a notification message containing the obtained power bank information and charging cabinet information, and send the notification message to the maintenance user terminal (such as the maintenance personnel's mobile phone, computer, etc.) to notify the maintenance personnel that a power bank needs to be taken away so that they can perform the relevant operations in a timely manner.

[0082] This application's implementation method improves the utilization rate and flexibility of charging cabinets by dynamically adjusting the status and location of power banks. By accurately calculating the number of card slots to be emptied and the number of power banks to be taken, optimized resource allocation and management are achieved. Furthermore, by promptly notifying maintenance personnel to perform relevant operations, the problem of users being unable to borrow or return power banks due to insufficient charging cabinet space is avoided, thus improving the user experience.

[0083] As shown in the above embodiment, in some embodiments of the present application, the above determining the target power bank based on the target power bank type can specifically include steps S701-S704. Figure 7

[0084] Step S701, when the target power bank type is full power bank, acquiring first electric quantity of all full power banks in the charging cabinet.

[0085] In the embodiments of the present application, when the target power bank type is full power bank, the terminal device can detect the electric quantity of all power banks in real time, thereby acquiring the electric quantity information of all full power banks.

[0086] Step S702, determining the target power bank in the order from high to low of the first electric quantity.

[0087] In the embodiments of the present application, the terminal device can sort the acquired electric quantity of full power banks, and select the power bank with the highest electric quantity as the target power bank, so as to ensure that the user or the system acquires the power bank with the most sufficient electric quantity.

[0088] Step S703, when the target power bank type is empty power bank, acquiring second electric quantity of all empty power banks in the charging cabinet.

[0089] In the embodiments of the present application, when the target power bank type is empty power bank, the terminal device can detect the electric quantity of all power banks in real time, thereby acquiring the electric quantity information of all empty power banks.

[0090] Step S704, determining the target power bank in the order from low to high of the second electric quantity.

[0091] In the embodiments of the present application, the terminal device can sort the acquired second electric quantity of empty power banks, and select the power bank with the lowest electric quantity (i.e. closest to empty state) as the target power bank, so as to ensure that the user acquires the power bank most in need of charging, or selects the power bank most meeting the requirements in some scenarios (such as recycling empty power banks for charging).

[0092] The embodiments of the present application avoid waste of resources and unnecessary energy consumption by reasonably selecting the target power bank, and improve the utilization efficiency of the charging cabinet and the power bank.

[0093] Figure 2 ​An implementation flowchart of another power exchange method provided by the embodiments of the present application is shown, which can be applied to the intelligent charging cabinet in the power exchange system. The power exchange system can further include a power bank, which can be a full-power power bank, an empty-power power bank, an intermediate-state power bank, etc. These power banks can be placed in the charging cabinet or borrowed by users.

[0094] Specifically, the above-mentioned power exchange method can include the following steps S201 to S204.

[0095] Step S201, when receiving the return request, the number of empty card slots in the charging cabinet and the position of the empty card slots are obtained.

[0096] In the embodiments of the present application, after receiving the return request of the user, the terminal device can detect the number and position of the empty card slots through the internal sensor.

[0097] Step S202, a target card slot is determined from the empty card slots, and the charging cabinet is controlled to open the target card slot.

[0098] In the embodiments of the present application, the terminal device can select an optimal empty card slot as the target card slot (for example, select the card slot closest to the user or the card slot most easily accessed) according to the number and position of the empty card slots, and control the charging cabinet to open the door or cover of the card slot, so as to facilitate the user to put the power bank into the charging cabinet and ensure that the power bank is correctly stored in an empty card slot.

[0099] Step S203, when detecting that the power bank is put into the target card slot, the type of the power bank is detected.

[0100] The type of the power bank includes a full-power power bank and an empty-power power bank, and the empty-power power bank is used to receive green power.

[0101] In the embodiments of the present application, the terminal device can detect whether the power bank is put into the target card slot through the internal sensor. When detecting that the power bank is put into the target card slot, the terminal device can detect the type (full-power or empty-power) of the power bank put into the target card slot through the detection circuit.

[0102] Step S204, when detecting that the type of the power bank is a full-power power bank, the charging cabinet is controlled to discharge the full-power power bank through the charging cabinet battery.

[0103] In the embodiments of the present application, if it is detected that the power bank put in is a full-power power bank, the terminal device can control the charging cabinet battery to be connected with the power bank, and transfer the power in the power bank to the charging cabinet battery through appropriate circuit (i.e. the discharging process).

[0104] In a typical application scenario of this application, a user can first take an empty power bank from the charging cabinet and charge it using a green power generation device. The empty power bank stores enough green energy to become a fully charged power bank. The user then returns the fully charged power bank to the charging cabinet. At this point, the charging cabinet can transfer the green energy from the fully charged power bank to its own battery and settle the corresponding electricity bill or other rewards with the user. Furthermore, the charging cabinet can use this green energy to charge other empty power banks for user use, thus realizing the personal storage and utilization of green energy.

[0105] This application's implementation method, through intelligent management of power bank storage and power exchange, can utilize electrical energy more effectively and reduce waste. Users can conveniently return power banks, and the charging cabinet can automatically handle different types of power banks, improving ease of use and user satisfaction.

[0106] like Figure 8 As shown, in some embodiments of this application, after detecting the power bank type, the above method may further include steps S801 to S804.

[0107] Step S801: When the power bank type is detected as an empty power bank, obtain the number of fully charged power banks and empty power banks in the charging cabinet.

[0108] In the embodiments of this application, when the power bank type is detected as an empty power bank, the terminal device can obtain the number of fully charged and empty power banks in the charging cabinet in real time through internal detection circuits or database records.

[0109] Step S802: Calculate the percentage of fully charged power banks and the percentage of empty power banks respectively.

[0110] In the embodiments of this application, the terminal device can calculate the percentage of fully charged power banks and the percentage of empty power banks based on the number of fully charged power banks and empty power banks in the charging cabinet and the total number of power banks.

[0111] Step S803: When the proportion of empty power banks is higher than the fourth preset proportion, calculate the number of power banks to be charged that will make the proportion of empty power banks reach the fourth preset proportion.

[0112] In the embodiments of this application, when the proportion of empty power banks is higher than the fourth preset proportion (e.g., 30%), the terminal device can calculate the number of power banks to be charged so that the proportion of empty power banks reaches the fourth preset proportion based on the current proportion of empty power banks, the fourth preset proportion, and the total number of power banks.

[0113] For example, assuming that the current proportion of empty power banks is X, the fourth preset proportion is Y, and the total number of power banks is T, the number of empty power banks that need to be charged is equal to (X-Y)*T / (1-Y).

[0114] In step S804, the charging cabinet is controlled to charge the empty power banks by the charging cabinet battery.

[0115] In the embodiments of the present application, the terminal device can select a corresponding number of empty power banks for charging according to the calculation result, thereby charging the excessive empty power banks and obtaining a corresponding number of full power banks, improving the utilization efficiency of electric energy and meeting the user demand.

[0116] The embodiments of the present application can automatically balance the distribution of electric energy in the charging cabinet, avoid the problem of insufficient electric energy caused by excessive empty power banks, thereby improving the utilization efficiency of electric energy and reducing the waste of electric energy. It can also improve the user experience and ensure that users can obtain full power banks in time.

[0117] As shown in Figure 9 In some specific embodiments of the present application, after calculating the proportion of full power banks and the proportion of empty power banks, respectively, the above method can further include steps S901 and S902.

[0118] In step S901, when the proportion of full power banks is higher than a fifth preset proportion, the number of power banks to be discharged to make the proportion of full power banks reach the fifth preset proportion is calculated.

[0119] In the embodiments of the present application, when the proportion of full power banks is higher than the fifth preset proportion (for example, 60%), the terminal device can calculate the number of full power banks to be discharged to make the proportion of full power banks reach the fifth preset proportion based on the current proportion of full power banks, the fifth preset proportion, and the total number of power banks.

[0120] For example, assuming that the current proportion of full power banks is A, the fifth preset proportion is B, and the total number of power banks is T, the number of full power banks that need to be discharged is equal to (A-B)*T / (1-B).

[0121] In step S902, the charging cabinet is controlled to discharge the full power banks by the charging cabinet battery.

[0122] In the embodiments of the present application, the terminal device can select a corresponding number of full power banks for discharging according to the calculation result, thereby transferring electric energy to the charging cabinet battery and obtaining a corresponding number of empty power banks.

[0123] The embodiments of the present application can automatically balance the distribution of electric energy in the charging cabinet, avoid the problem of insufficient empty power banks caused by excessive full power banks, and cannot meet the user demand.

[0124] As shown in the above embodiments of the present application, the method can further include steps S1001 to S1007. Figure 10

[0125] Step S1001, when it is detected that a power bank is put into the target slot, the number of empty slots in the charging cabinet is acquired, and the empty slot ratio is calculated.

[0126] In the embodiments of the present application, after detecting that a power bank is put into the target slot, the terminal device can acquire the number of remaining empty slots in real time through sensors or database records, and calculate the empty slot ratio.

[0127] Step S1002, when the empty slot ratio is lower than the sixth preset ratio, the number of slots to be emptied to make the empty slot ratio reach the sixth preset ratio is calculated.

[0128] In the embodiments of the present application, when the empty slot ratio is lower than the sixth preset ratio (for example, 20%), the terminal device can calculate the number of slots to be emptied according to the current empty slot ratio, the sixth preset ratio, and the total number of slots.

[0129] For example, assuming that the current empty slot ratio is X, the sixth preset ratio is Y, and the total number of slots is T, the number of slots to be emptied is (Y-X)*T / (1-Y).

[0130] Step S1003, the number of intermediate state power banks in the charging cabinet is acquired, the intermediate state power bank being a power bank that is neither fully charged nor empty.

[0131] In the embodiments of the present application, the terminal device can count the number of intermediate state power banks by detecting the power state of the power bank in each slot.

[0132] Step S1004, the number of slots to be emptied is compared with the number of intermediate state power banks.

[0133] In the embodiments of the present application, the terminal device can directly compare the two number values to determine whether the number of intermediate state power banks is sufficient to meet the demand for emptying the slots.

[0134] Step S1005, if the number of intermediate state power banks is greater than or equal to the number of slots to be emptied, a corresponding number of power banks to be taken away is determined from the intermediate state power banks according to the number of slots to be emptied.

[0135] In the embodiments of the present application, if the number of intermediate state power banks is greater than or equal to the number of slots to be emptied, the terminal device can select a corresponding number of power banks from the intermediate state power banks as the power banks to be taken away according to the number of slots to be emptied, so as to free up empty slots. ​

[0136] Step S1006, obtaining the power bank information of the power bank to be taken away and the charging cabinet information of the charging cabinet.

[0137] In the embodiments of the present application, the terminal device can extract the detailed information of the power bank to be taken away and the charging cabinet from the database, providing data support for generating notification information.

[0138] Step S1007, generating notification information according to the power bank information and the charging cabinet information, and sending the notification information to the maintenance user terminal.

[0139] In the embodiments of the present application, the terminal device can generate notification information containing detailed information of the power bank and the charging cabinet according to the extracted information, and send it to the maintenance user terminal through the network to inform the maintenance personnel to come to take away the power bank to be taken away, so as to free up the empty card slot.

[0140] The embodiments of the present application can automatically balance the use of card slots in the charging cabinet, avoid the shortage or waste of card slot resources, improve the operation and maintenance efficiency of the charging cabinet, quickly locate and process the power bank to be taken away through notification information, so as to ensure the reasonable distribution of power banks in the charging cabinet and improve the efficiency of electric energy utilization.

[0141] As shown in Figure 11 In some embodiments of the present application, the electric energy exchange system further comprises a backup battery, the backup battery is electrically connected with the charging cabinet, and the method further comprises steps S1101 to S1104.

[0142] Step S1101, detecting the electric quantity of the charging cabinet battery.

[0143] In the embodiments of the present application, the terminal device can monitor the electric quantity of the charging cabinet battery in real time through the electric quantity detection device or sensor built in the charging cabinet.

[0144] Step S1102, when the electric quantity of the charging cabinet battery is higher than the first preset electric quantity, controlling the charging cabinet battery to discharge to the backup battery.

[0145] In the embodiments of the present application, the terminal device can automatically open the discharge channel to transfer electric energy to the backup battery when the electric quantity of the charging cabinet battery exceeds the first preset electric quantity according to the feedback of the electric quantity detection device, avoiding the waste of electric energy or the damage of the battery caused by the too high electric quantity of the charging cabinet battery, and charging the backup battery with the excess electric energy at the same time.

[0146] Step S1103, obtaining the electric quantity of the backup battery.

[0147] In the embodiments of the present application, the terminal device can monitor the electric quantity of the backup battery in real time through the electric quantity detection device or sensor built in the backup battery.

[0148] Step S1104: When the backup battery power is higher than the second preset power, a control command is sent to the backup battery to instruct it to upload electrical energy to the grid through the inverter.

[0149] In the embodiments of this application, the terminal device can send control commands to the backup battery and inverter when the battery level exceeds a second preset level, based on the feedback of the backup battery's power level. The commands instruct the backup battery and inverter to work together to convert the DC power in the backup battery into AC power and upload it to the power grid. This avoids energy waste caused by excessive backup battery power and simultaneously realizes energy recovery and reuse, thereby improving energy efficiency.

[0150] This application's implementation method avoids energy waste by rationally utilizing the electrical energy of the charging cabinet's batteries and backup batteries. When the backup battery's charge is too high, the electrical energy can be uploaded to the power grid, realizing the recovery and reuse of electrical energy.
