[0030] FIG1 is a block diagram of the principle structure of a control system of a mobile power supply provided in an embodiment of the present application. 1 , the control system of the power bank includes: a wireless charging module 100, a power module 200, a control module 300, a storage module 400, a power module 500, an information interaction module 600, and an interface interaction module 700. The wireless charging module 100 is configured to simultaneously provide multiple wireless charging functions, providing wireless charging for multiple devices to be charged; the power module 200 is configured to simultaneously provide multiple wired charging functions, providing wired charging for multiple devices to be charged; the control module 300 is connected to the wireless charging module 100 and the power module 200, respectively, and is configured to provide matching voltage and power for the wireless charging module 100 and the power module 200; the control module 300 is also connected to the storage module 400 and is configured to read, store, and transmit power bank usage information; the control module 300 is also connected to the power module 500 and is configured to control the power bank to input / output with optimal parameters; the control module 300 is also connected to the information interaction module 600 and the interface interaction module 700, respectively; and the power module 200 is further configured to provide simultaneous input / output functions.

[0031] The device to be charged may be a portable electronic device such as a mobile phone, a portable computer, a drone, a camera, a watch, a bracelet, a headset, etc. The charging method of the device to be charged may include a wireless charging method and / or a wired charging method.

[0032] The control module 300 includes a microprocessor, which includes one or both of random access memory (RAM) and read-only memory (ROM) to store software instructions. The microprocessor also includes non-volatile memory, such as electrically erasable programmable read-only memory (EEPROM).

[0033] Among them, the wireless charging module 100 and the power module 200 are respectively connected to the control module 300. The control module 300 can cooperate with the wireless charging module 100 and the power module 200 according to the power demand of the device to be charged, provide the required matching voltage and power, automatically identify the optimal parameters, and realize the function of the mobile power supply to charge the device to be charged with the optimal charging parameters.

[0034] The storage module 400 is connected to the control module 300, and the control module 300 can cooperate with the storage module 400 to read, store, and transmit mobile power usage information. The power module 500 is connected to the control module 300, and the control module 300 can cooperate with the power module 500 to optimize the input / output parameters of the mobile power module, thereby increasing the life of the mobile power module and improving the overall life and safety of the mobile power. The control module 300 is connected to the information interaction module 600 and the interface interaction module 700 respectively. The control module 300 can cooperate with the information interaction module 600 and the interface interaction module 700 to interact with the user or mobile power administrator, allowing the user or mobile power administrator to view, adjust, and monitor the mobile power parameters.

[0035] In this embodiment, the control system of the power bank is implemented as follows: Referring to FIG1 , for example, assume that user A has five devices to be charged simultaneously and require wired or wireless charging. Assume that three of these devices have wireless charging capabilities and the other two require wired charging. The three devices requiring wireless charging are wirelessly charged via the wireless charging module 100, while the two devices requiring wired charging are wired charged via the power module 200. This allows for simultaneous provision of multiple wireless and wired charging functions for multiple devices of the same user, thereby enabling simultaneous wired and / or wireless charging for multiple devices when the user carries multiple devices, improving adaptability and charging convenience. Furthermore, when the power bank is low or insufficient and requires charging, power can be simultaneously input / output via the power module 200. This allows the power bank to be continuously and stably charged while the wireless charging module 100 and the power module 200 of the power bank can output power for a long period of time, still providing simultaneous wired and / or wireless charging for multiple devices, meeting user needs, improving convenience, and enhancing user experience. When using the simultaneous input / output function, the power bank can perform the following functions: First, enable pass-through mode. This allows all incoming power to be supplied to the device being charged first. The power bank only performs circuit switching, with the power bank's own battery pack providing power later. Second, it allows the device being charged and the power bank to be charged simultaneously according to a set policy. In this case, both the device being charged and the power bank can be charged simultaneously through the input port. The first function is suitable for situations where the user urgently needs to replenish power, while the second function is suitable for normal charging conditions. Furthermore, during use of the power bank, the control module 300 collaborates with the storage module 400 to read, store, and transmit power bank usage information. The control module 300 collaborates with the information interaction module 600 and the interface interaction module 700 to interact with the user or the power bank administrator, enabling them to view, adjust, and monitor power bank parameters, greatly enhancing user convenience and user experience.

[0036] In this embodiment, a control system of a mobile power supply is provided, which includes: a wireless charging module, a power module, a control module, a storage module, a power module, an information interaction module and an interface interaction module; wherein the wireless charging module is configured to simultaneously provide multiple wireless charging functions and provide wireless charging for multiple devices to be charged; the power module is configured to simultaneously provide multiple wired charging functions and provide wired charging for multiple devices to be charged; the control module is respectively connected to the wireless charging module and the power module, and is configured to provide matching voltage and power for the wireless charging module and the power module; the control module is also connected to the storage module, and is configured to read, store and transmit usage information of the mobile power supply; the control module is also connected to the power module, and is configured to control the input / output of the mobile power supply with optimal parameters; the control module is also respectively connected to the information interaction module and the interface interaction module; the power module is also configured to provide simultaneous input / output functions. It can be seen from this that the mobile power supply can charge multiple devices to be charged simultaneously in wired and / or wireless ways, and can provide simultaneous input / output functions, that is, it can charge multiple devices wired and / or wirelessly while charging the mobile power supply, expand the range of charging options, enhance adaptability, meet users' charging needs for multiple devices and multiple charging methods, improve user experience, and bring great convenience to users.

[0037] Figure 2 is a block diagram of the principle structure of another mobile power supply control system provided in an embodiment of the present application. Based on the above embodiment, the wireless charging module optionally includes at least: a wireless charging power circuit and multiple wireless charging coils; each wireless charging coil is connected to the wireless charging power circuit; and the wireless charging power circuit is also connected to the control module.

[0038] It should be noted that the specific number of wireless charging coils included in the wireless charging module can be set according to actual conditions.

[0039] Exemplarily, referring to Figure 2, the wireless charging module includes at least: a first wireless charging coil 101, a second wireless charging coil 102, a third wireless charging coil 103 and a wireless charging power circuit 104; the first wireless charging coil 101, the second wireless charging coil 102 and the third wireless charging coil 103 are all connected to the wireless charging power circuit 104; the wireless charging power circuit 104 is also connected to the control module 300.

[0040] The wireless charging module includes multiple wireless charging coils. When combined with magnetic coils, the wireless charging coils can be combined and upgraded to form wireless magnetic charging coils. If the device being charged has wireless charging capabilities, the user can place the device in contact with the wireless charging coil area of ​​the power bank. The power bank automatically recognizes the device and enables the control module 300 to control the power module 500 to charge the device through the wireless charging module 100. The wireless charging module 100 can work with the control module 300 to independently control the operating status of one or more wireless charging coils. One or more wireless charging coils can be activated independently or all can operate simultaneously. When multiple wireless charging coils operate simultaneously, they are independent of each other, unaffected by charging functionality, and can operate simultaneously at maximum output power. Depending on the power requirements of the device being charged, one or more wireless charging coils can operate simultaneously at the maximum output power set by the power bank or at the optimal power required by the external device being charged. The charging power strategy can also be determined by the power required by the user's device and the internal temperature of the power bank. The charging powers of multiple wireless charging coils can be different and independent of each other.

[0041] For example, in this embodiment, the wireless charging module includes three wireless charging coils. These three wireless charging coils are: a first wireless charging coil 101, a second wireless charging coil 102, and a third wireless charging coil 103. The wireless charging module includes a wireless charging power circuit 104, which supplies power to the first wireless charging coil 101, the second wireless charging coil 102, and the third wireless charging coil 103. When a user needs to wirelessly charge one or more devices to be charged, they only need to contact and fit each device to the wireless charging area corresponding to the wireless charging coil corresponding to the mobile power supply according to the actual number of devices required to perform wireless charging.

[0042] As a specific implementation manner, optionally, the first wireless charging coil is a mobile phone wireless charging coil, the second wireless charging coil is a headset wireless charging coil, and the third wireless charging coil is a watch wireless charging coil.

[0043] The wireless charging power circuit supplies power to the mobile phone wireless charging circuit corresponding to the mobile phone wireless charging coil and the headphone wireless charging circuit corresponding to the headphone wireless charging coil. The watch wireless charging power circuit also converts power to power the watch wireless charging circuit corresponding to the watch wireless charging coil. The mobile phone wireless charging circuit, headphone wireless charging circuit, and watch wireless charging circuit all have wireless transceiver capabilities, providing wireless power that meets the load protocol requirements.

[0044] It should be noted that the specific device that each wireless charging coil can be used for wireless charging can be set according to the situation, and the solution of this embodiment is only an exemplary illustration of one implementation situation.

[0045] Optionally, the power module includes at least one or more bidirectional interfaces and one or more unidirectional interfaces.

[0046] It should be noted that the specific number of bidirectional interfaces and the number of unidirectional interfaces included in the power module can be set according to actual conditions.

[0047] For example, continuing to refer to Figure 2, the power module includes at least: a first bidirectional interface 201, a second bidirectional interface 202, a first unidirectional interface 203, a second unidirectional interface 204, a third unidirectional interface 205, a first interface power circuit 206, a second interface power circuit 207 and a third interface power circuit 208; wherein, the first bidirectional interface 201 and the second bidirectional interface 202 are both connected to the first interface power circuit 206, and the first interface power circuit 206 is also connected to the control module 300; the first unidirectional interface 203 is connected to the second interface power circuit 207, and the second interface power circuit 207 is also electrically connected to the control module 300; the second unidirectional interface 204 and the third unidirectional interface 205 are both connected to the third interface power circuit 208, and the third interface power circuit 208 is also connected to the control module 300.

[0048] Among them, the power module includes multiple wired charging interfaces and their related circuits. Under the control of the control module, the power module 200 can simultaneously control the working status of all interfaces, and the working status of each interface can be controlled independently without affecting each other. For example, in this embodiment, the power module includes 5 wired charging interfaces as an example. These 5 wired charging interfaces are respectively a first bidirectional interface 201, a second bidirectional interface 202, a first unidirectional interface 203, a second unidirectional interface 204 and a third unidirectional interface 205.

[0049] Exemplarily, all interfaces of the mobile power supply include 2 USB-A interfaces, 2 USB-C interfaces, and 1 DC interface. Among them, the first bidirectional interface 201 is a USB-C1 interface. The second bidirectional interface 202 is a DC interface, the first unidirectional interface 203 is a USB-C2 interface, the second unidirectional interface 204 is a USB-A1 interface, and the third unidirectional interface 205 is a USB-A2 interface. Among them, the first bidirectional interface 201 and the second bidirectional interface 202 can realize simultaneous input / output functions. The above interfaces can be turned on independently or all of them can work together at the same time, which can be determined according to the power demand of the device to be charged.

[0050] For example, when the above interfaces are operating simultaneously, all interfaces can operate at the set maximum input / output power, or they can simultaneously operate at the optimal power required by the device being charged. The power bank is also designed with simultaneous input / output functionality. In this mode, all interfaces can operate simultaneously, with USB-C and DC as inputs, and USB-A, USB-C, DC, and each wireless charging coil as outputs. For example, while one USB-C and DC interface can operate as inputs, two USB-A interfaces and one USB-C interface can also operate simultaneously as outputs. Simultaneously, the three wireless charging coils controlled by the wireless charging module can also operate simultaneously. In other words, in this scenario, two interfaces function as inputs, while the remaining three interfaces and the three wireless charging coils function as six outputs. For example, when simultaneous input / output mode is enabled, if one interface is reserved for receiving power and the remaining interfaces function as outputs, up to seven portable electronic devices can be powered simultaneously, providing significant convenience and enhancing the user experience.

[0051] Exemplarily, referring to Figure 2, the power module also includes a first interface power circuit 206, a second interface power circuit 207, and a third interface power circuit 208. Among them, the first interface power circuit 206 has a bidirectional power supply function, which can not only supply power to the outside and provide power supply that meets the requirements of the load protocol, but also input power internally through the first bidirectional interface 201 or the second bidirectional interface 202 (i.e., the USB-C1 interface or the DC interface) to charge the battery pack. Among them, the second interface power circuit 207 realizes external power supply through the first unidirectional interface 203 and provides power supply that meets the requirements of the load protocol. The third interface power circuit 208 supplies power to the outside and has a second unidirectional interface 204 and a third unidirectional interface 205, which are used to provide power supply that meets the requirements of the load protocol.

[0052] Optionally, continuing to refer to Figure 2, the power module includes: a battery pack 501, a fuel meter unit 502 and a BMS circuit 503; the battery pack 501 is connected to the BMS circuit 503, the BMS circuit 503 is connected to the fuel meter unit 502, and the fuel meter unit 502 is respectively connected to the control module 300, the wireless charging module 100 and the power module 200.

[0053] The battery module includes a battery pack 501, a fuel meter unit 502, and a BMS circuit 503. The battery pack 501 includes batteries, and the control module can control the battery pack 501. The capacity of the battery pack 501 can be customized and adjusted according to the user's actual needs. For example, if the user requires a large capacity and the design scenario requires charging multiple devices simultaneously for a long time, the number of batteries in the battery pack within the mobile power supply can be increased accordingly, and the series and parallel connection of the batteries can also be adjusted and customized accordingly.

[0054] The power module 500 manages the input / output on / off status of the battery pack 501 through the control of the control module 300. For example, when using the simultaneous input / output function, the user can choose to enable pass-through mode. When pass-through mode is enabled, the input / output does not pass through the power module 500, but is directly output through the control module 300 and power module 200 on the circuit board. The benefits of this setting are: on the one hand, it reduces power loss; on the other hand, it reduces the number of cycles of the battery in the power module, thereby increasing the lifespan of the battery and the entire product.

[0055] The power module 500 can also monitor environmental indicators of the battery pack 501, such as temperature, to monitor the operating temperature of the battery pack 501 and provide a safety protection function. Furthermore, the power module 500 can cooperate with the control module 300 to monitor the health of the battery pack 501 and estimate the number of battery cycles according to set rules. For example, based on the set total battery pack capacity, the established rule is to monitor the actual input / output of one full capacity cycle as the battery pack cycle count plus one. All of the above can be displayed and reminded to the user and the mobile power supply administrator through the interface interaction module 700 through logical control and data analysis, thereby achieving an early warning function for the safety performance of the entire product. For example, if the power module 500 cooperates with the control module 300 to monitor and analyze that the battery pack 501 has reached 300 cycles, the interface interaction module 700 will display a reminder to the user, warning that the battery pack life is decreasing and reminding the user to pay more attention to safety during use.

[0056] The power module 500 includes a battery pack 501, which includes one or more batteries, such as one or more rechargeable lithium batteries. The battery packs shown above are merely examples of lithium batteries. The battery packs included in the power module 500 are removable from the mobile power supply structure, meaning they are detachable and replaceable. When the mobile power supply's battery pack is low on power, the user can replace it.

[0057] The fuel gauge unit 502 collects the voltage, current, and temperature of the battery pack 501 and provides this information to the control module via I2C communication. The BMS circuit 503 monitors the battery pack voltage, current, and temperature and implements related battery pack protection functions. Furthermore, the fuel gauge unit accurately measures the remaining capacity of the device, which is then accurately calculated by the control module and displayed in real time on the display. This allows for precise real-time power consumption across each interface, ensuring accurate power consumption across the entire power bank.

[0058] Optionally, with continued reference to FIG. 2 , the information interaction module 600 includes at least a communication module 601 , and the communication module 601 is connected to the control module 300 .

[0059] The information interaction module 600 includes a communication module 601, which can include a wired network, a wireless (Wireless Fidelity, Wi-Fi) network, a cellular network, an Internet of Things (IoT) module, a Long Range Radio (LORA) module, and the like. For example, the communication module 601 in this embodiment can be a Bluetooth / Wi-Fi module. Its main uses are: first, communicating with the charging station. The power bank connects to the charging station via the Bluetooth / Wi-Fi module and transmits its basic information to the charging station, which then guides the user to select a specific power bank. After confirmation, the charging station also sends a rental instruction to the power bank via the Bluetooth / Wi-Fi module, enabling the user to access or rent the power bank when used with the charging station. Second, the information interaction module 600 can connect to other terminals, such as mobile phone apps, primarily to upgrade the product's firmware. For example, the power bank can connect to the manufacturer's data management app or other dedicated apps via the Bluetooth module to upgrade the product's firmware. When there is no manufacturer data management APP or other dedicated APP support environment, the mobile power supply can also be connected to the charging station through the information interaction module. The charging station issues a program upgrade instruction, which can be displayed on the display screen through the interface interaction module 700. The user or mobile power supply administrator can operate the upgrade.

[0060] Optionally, continuing to refer to FIG. 2 , the interface interaction module 700 includes at least a display unit 701 and a button 702 , and both the display unit 701 and the button 702 are connected to the control module 300 .

[0061] The interface interaction module 700 primarily comprises a display unit 701 and buttons 702. The display unit 701 can be a display such as a screen. The display is used to display the product's operating status and the human-computer interaction settings interface. For example, the display can include an organic electroluminescent display or an organic liquid crystal display. The buttons can include a power button and up / down adjustment buttons for powering the product on and off and selecting menus. The display interface can be customized based on the user's needs. The control module 300, in conjunction with the power module 200, collects information from various interfaces and other power bank information, such as the real-time temperature, remaining battery charge, and remaining operating time at temperature sampling points located within the battery pack or elsewhere within the power bank. This information is displayed in real time on the power bank's display via the interface interaction module 700 for viewing by the user or power bank administrator. Furthermore, the interface interaction module 700's display and buttons can be used to provide parameter adjustment functionality for the user or power bank administrator, including adjusting interface voltage, menu language, timed power on / off, factory reset, and the power bank's firmware version number. The interface status adjustment operation can adjust the output power or output protocol voltage of one or more interfaces. For example, the DC interface voltage input / output accuracy is adjusted to 0.1V. This can be adjusted by the user through the combination of the screen and buttons.

[0062] FIG3 is a structural diagram of a control system of a mobile power supply provided in an embodiment of the present application. Exemplarily, referring to FIG3 , the control module includes a master microcontroller unit (MCU) and a slave MCU, the storage module includes an EEPROM circuit, the interface interaction module includes a display screen and buttons, and the information interaction module includes a Bluetooth / WIFI module. Exemplarily, the first bidirectional interface, the second bidirectional interface, the first unidirectional interface, the second unidirectional interface, and the third unidirectional interface are respectively a USB-C1 interface, a DC interface, a USB-C2 interface, a USB-A1 interface, and a USB-A2 interface, and the first interface power circuit, the second interface power circuit, and the third interface power circuit are respectively a C1 port power circuit, a C2 port power circuit, and an A port power circuit. The first wireless charging coil, the second wireless charging coil, and the third wireless charging coil are respectively a mobile phone wireless charging coil, a headset wireless charging coil, and a watch wireless charging coil. Among them, the wireless charging power circuit converts the power of the watch wireless charging power circuit to power the watch wireless charging circuit corresponding to the watch wireless charging coil. Among them, the EEPROM, wireless charging power circuit, C1 port power circuit, C2 port power circuit, A port power circuit, fuel meter unit and slave MCU are all connected to the main MCU, and the Bluetooth / WIFI module, display screen and buttons are all connected to the slave MCU.

[0063] In one embodiment, the C1 port power circuit features bidirectional power supply functionality. It can provide external power, complying with load protocol requirements, and internal power input via a DC interface or USB-C1 interface to charge the battery pack. The C2 port power circuit provides external power via the USB-C2 interface, complying with load protocol requirements. The A port power circuit provides external power, with two output interfaces, USB-A1 and USB-A2, complying with load protocol requirements. The wireless charging power circuit provides power to mobile phone and headphone wireless charging coils, while also providing power to the watch wireless charging coil after power conversion via the watch charging power circuit. The fuel gauge unit collects battery pack voltage, current, and temperature information and provides battery-related information to the main MCU via I2C communication. The BMS circuit monitors battery pack voltage, current, and temperature information and implements related battery pack protection functions. Battery pack protection functions include undervoltage protection, overvoltage protection, overcurrent protection, and high temperature protection. The main MCU communicates with the C1 port power circuit, C2 port power circuit, fuel gauge unit, and EEPROM circuit via I2C to implement information collection, power control, and storage. At the same time, the main MCU is used to control the A port power circuit and the wireless charging power circuit to enable and monitor the watch status.

This extends the product lifespan and ensures user safety during use.

[0076] It should be noted that each interface of the mobile power supply can work independently and will not affect each other. Each interface of the mobile power supply can work simultaneously, and the strategy for working simultaneously can be set and adjusted.

[0077] This power bank supports uninterruptible power supply (UPS) with a switching response time of less than 10ms. When using the simultaneous input / output function, if the input is interrupted for any reason, the power bank will instantly switch to powering the connected electronic device from the battery pack in the power module within a response time of less than 10ms. For example, a user might use the power bank to charge a portable monitor during a meeting, meeting their mobile office needs. The power bank connects to a wall outlet via an adapter via the DC port, while simultaneously charging the portable monitor via the USB-C port via a cable harness. In this scenario, the power bank uses the simultaneous input / output function. Users can select pass-through mode, which bypasses the battery pack for simultaneous input / output. If a building power outage occurs, the wall outlet immediately loses power, disrupting the power bank's input. The power bank's control circuitry and the power module instantly switch power to the battery pack, preventing the portable monitor from losing power as the building loses power. This provides users with an uninterrupted experience and significant convenience.

[0078] It should be noted that the length and weight of the power bank itself are related to the overall product design capacity. When the expected capacity increases, the number of batteries in the battery pack can be increased, and accordingly, the product length and weight will increase accordingly.

[0079] Figure 9 is a schematic diagram of a charging station and a mobile power supply provided in an embodiment of the present application. Referring to Figure 9, an embodiment of the present application further provides a charging station, which is adapted to the mobile power supply provided in any embodiment of the present application.

[0080] For example, Figure 9 shows a schematic diagram of a power bank and its charging station, including the charging station and the power bank. The charging station includes a charging base and a power supply circuit. The power supply circuit is located within the charging base. The charging base includes multiple slots, each of which is equipped with charging terminals. The charging terminals are connected to the power supply circuit. Each power bank is placed in a slot. When placed in a slot, its interface connects to the charging terminals, which then charge the power bank. As shown in Figure 9, the charging base includes eight slots and can simultaneously charge 1-8 power banks. The power bank's input is configured as a DC or USB-C port, and the charging terminals within the charging slots can be configured as DC or USB-C ports. The position of the charging terminals within the slots must align with the position of the ports on the power bank, ensuring that when the power bank is placed in the slot, the charging terminals connect to the ports on the power bank, allowing the charging station to charge the power bank. The charging terminals within each slot can be different to meet the needs of different users. Power banks placed in each slot can be charged independently, and power banks placed in different slots do not affect each other's charging. In addition, the mobile power supply only needs to be placed in the slot. The shape of the slot and the shape of the mobile power supply can be set according to actual conditions. It is only necessary to ensure that when each mobile power supply is placed in the slot, its input interface can be connected to the charging terminal.

[0081] The charging station is equipped with a circuit control module, an information storage module, a mode management module, and an information communication module. The specific functions are as follows.

[0082] The circuit control module is configured to control the charging process of the power bank at the charging station. Each port can charge the power bank at different power levels without affecting each other. Each port can independently identify the power bank's status and charge level, charging the power bank at the optimal power level.

[0083] The information storage module can store part or all of the current status information of the charging station and the status information of the mobile power bank. The current status information of the charging station includes the safety monitoring indicators of the charging station, such as the temperature of the temperature sampling points set up inside the charging station and the ambient humidity of the charging station. These are very important environmental parameters for products using batteries and are related to the safety performance of the mobile power bank. The status information of the mobile power bank includes the number of times the mobile power bank has been taken out, the remaining power of the mobile power bank, the battery health of the mobile power bank, and the operations performed after the mobile power bank was taken out by the user. The above information can be stored wirelessly, such as the mobile power bank interacting with and storing information with the charging station via Bluetooth, or through contact, such as through the USB-C charging terminal. The USB-C type terminal can transmit both power and data. When the mobile power bank is connected to the charging station via the USB-C terminal, the above status information is transmitted and stored while replenishing the power.

[0084] Before the mode management module is used with a charging station, the charging station administrator can set its mode. These include user access charging mode, user access free mode, user restricted area use mode, etc. Under different management modes, the control strategy of the circuit control module will also be different. For example, in the user access charging mode, the mode management module can be specifically configured to set the charging standard of the charging station and whether all charging terminals of the charging station charge the mobile power supply at maximum power. For example, in the user restricted area use mode, the mode management module can be specifically configured to scan the mobile power supply by the Bluetooth module of the charging station. Mobile power supplies scanned within a range of 20 meters of the charging station can be used normally by the user; when out of range, the mobile power supply will automatically shut down and cannot be turned on for user use because it cannot receive instructions from the charging station.

[0085] The information communication module, on the one hand, obtains the status information of the mobile power supply wirelessly or in contact mode and then stores it. On the other hand, the charging station will be connected to the cloud-based backend server wirelessly or by wire, and upload various types of information such as the charging station mode information and the mobile power supply status information for storage. The charging station can communicate, transmit data, and back up data with the cloud-based backend server wirelessly, including Bluetooth, WIFI, etc. It can also communicate, transmit data, and back up data with a mobile terminal such as a PC APP through a wired method, such as through an Internet cable. The information communication module includes a Bluetooth communicator and a network communicator.

[0086] The system consisting of charging stations and mobile power supplies can be divided into several main roles. First, the end user, after wirelessly connecting to the charging station through an information operation terminal such as a mobile phone app, sends instructions to the charging station. After the charging station and the mobile power supply transmit the instructions, the user can take the mobile power supply and use it normally according to the mode set by the system administrator. Second, the charging station system administrator, after wirelessly connecting to the charging station through a terminal such as a PC app, sets the charging station mode. At the same time, he checks and sets various parameters to ensure the normal operation and system security of the charging station system under use. Third, the cloud service system administrator provides cloud system services, can obtain various device information backed up in the cloud, and ensure smooth network and real-time connection between the cloud service system and the charging station. Depending on different usage modes, the charging station system can be set up in various public places such as shared office spaces, within companies, and inside shopping malls.

[0087] It should be understood that the various forms of the processes shown above can be used to reorder, add, or delete steps. For example, the steps described in this application can be performed in parallel, sequentially, or in a different order, as long as the desired results of this application can be achieved.
