Description

Technical Field

[0001] This invention relates to the field of charging technology, and in particular to a mobile charging station and control method, a mobile charging system and control method. Background Technology

[0002] Currently, mobile devices are powered by power banks, and when the power bank's charge is low, it needs to be replaced with a new one.

[0003] In large-scale power consumption scenarios, power banks are often characterized by their large size and heavy weight. When replacing a power bank, users have to bear a heavy burden when carrying and operating it, and they also have to bear the additional cost of carrying the bulky power bank. This results in poor flexibility when replacing a power bank and a heavy burden on users. In large-scale power consumption scenarios, this brings a significant burden to users in terms of carrying and operating, and it is difficult to meet the actual use needs.

[0004] In existing technologies, charging stations are located in fixed locations. When users find that their power banks cannot meet their power needs, they actively search for a charging station to replace or recharge their existing power banks. However, during this search, the power bank may have stopped supplying power, causing a forced power outage to the powered device, potentially leading to safety risks or data loss. In other words, existing power banks suffer from low power supply reliability. Furthermore, in office areas with numerous devices and concentrated charging demands, fixed charging station locations can easily lead to charging resource shortages and long waiting times for users, reducing the efficiency of power bank replacement. In addition, while charging station locations are relatively fixed, users of power banks may be constantly moving. When a power bank's charge is low, users must travel to these fixed locations to replace or recharge it, unable to flexibly choose a charging location based on individual needs or changing locations. Therefore, this method lacks flexibility.

[0005] The existing charging methods result in low power supply reliability of power banks, and the efficiency and flexibility are insufficient when replacing power banks. Summary of the Invention

[0006] This invention provides a portable charging station and its control method, as well as a portable charging system and its control method. The portable charging station can automatically monitor the status information of the power bank and automatically move to the user's location in case of abnormal conditions, facilitating power bank replacement and providing timely charging services. This effectively solves the problems of low charging efficiency and low flexibility of mobile devices in office environments.

[0007] The portable charging station provided in this embodiment offers user convenience in some cases, enabling flexible charging of power banks and continuous power supply to devices, significantly improving user power efficiency and power bank utilization. In this embodiment, the portable charging system can control multiple portable charging stations. The power banks at different charging stations may be of different models. The portable charging system can identify the model of the power bank used by the user and move the portable charging station with that model to the user's location, facilitating the user's replacement with the corresponding model. If, after comprehensive evaluation, the portable charging station determines that the user's model does not meet the battery replacement requirements and no second power bank of the same model is available, the portable charging station can prompt the user to replace it with another model according to a preset battery replacement product logic. When the portable charging station moves to the user's location, it can identify the power bank with the highest battery level in the station and flash its light, prompting the user to remove and replace it.

The positioning module is used to determine the location information of the power bank; the status monitoring module is used to monitor the status of the power bank and generate status signals. The control module is used to generate a first control signal based on the status signal of the first mobile power supply and the location information of the first mobile power supply; The mobile module is used to move to the location of the first mobile power source according to the first control signal.

Alternatively, the location information of the second power bank is identified by the connection signal of the portable charging station, and the status signal of the first power bank is obtained by the status monitoring module on the first power bank. The control module generates a first control signal based on the status signal of the first mobile power supply, the location information of the first mobile power supply, and the location information of the second mobile power supply. The mobile module moves to the location of the first mobile power source according to the first control signal.

[0010] According to another aspect of the present invention, a mobile charging system is provided, the mobile charging system including the mobile charging station described in any embodiment of the present invention, the mobile charging system being capable of executing the mobile charging station control method described in any embodiment of the present invention.

[0011] Optional, the portable charging system also includes: A cloud server is communicatively connected to the portable charging connection. When the cloud server or the main control unit of the portable charging station detects that the first portable power bank at the target location has insufficient power, it controls the matching portable charging station to move to the target location according to a planned path. After the user at the target location removes the fully charged second portable power bank and puts the first portable power bank back into the portable charging station, the portable charging station is used to automatically confirm the placement status and identity information of the first portable power bank through inductive identification technology, and upload a "placement completed" signal to the main control unit or the cloud server. The main control unit or cloud server is used to schedule the mobile charging station to return to the charging base station along the planned path based on the received "placement complete" signal.

[0012] Optional, the portable charging system also includes: The charging base station is used to charge the mobile charging station.

[0013] Optionally, the mobile charging station is also configured to, during the process of the mobile charging station returning to the charging base station, if the mobile charging station receives or detects any target location again, dynamically interrupt the current task of returning to the charging base station according to the task priority, and respond to the power replenishment needs of the mobile power supply at the high-priority target location.

[0014] Optionally, the mobile charging station is further configured to continuously monitor its own charging status and external task requests during the charging process from the charging base station to the mobile charging station; if the monitoring time exceeds a second preset time and the mobile charging station does not receive the target location, the mobile charging station will maintain the charging state and switch to sleep mode during the charging process.

[0015] According to another aspect of the present invention, a control method for a portable charging system includes: When the main control unit of the cloud server or the mobile charging station detects that the power of the first mobile power source at the target location is insufficient, the main control unit or the cloud server controls the matching mobile charging station to move to the target location according to the planned path. After the user at the target location removes the fully charged second power bank and puts the first power bank back into the portable charging station, the portable charging station automatically confirms the placement status and identity information of the first power bank through inductive identification technology, and uploads a "placement complete" signal to the main control unit or cloud server. The main control unit or cloud server, based on the received "placement complete" signal, schedules the mobile charging station to return to the charging base station along the planned path; The mobile charging station charges at the charging base station.

[0016] Optionally, after the main control unit or cloud server schedules the mobile charging station to return to the charging base station along the planned path based on the received "placement complete" signal, the method further includes: During the process of the mobile charging station returning to the charging base station, if the mobile charging station receives or detects any target location again, it will dynamically interrupt the current task of returning to the charging base station according to the task priority, and respond to the power replenishment needs of the mobile power supply at the high-priority target location.

[0017] Optionally, during the charging process at the mobile charging station at the charging base station, the method further includes: During the process of the charging base station charging the mobile charging station, the mobile charging station continuously monitors its own charging status and external task requests. If the monitoring time exceeds the second preset time and the mobile charging station does not receive the target location, the mobile charging station will maintain the charging state and switch to sleep mode during the charging process.

[0018] The technical solution of this invention involves a control module sending a first control signal when it detects an abnormality in the status signal of the first power bank. This control signals the movement module to move the portable charging station to the location of the first power bank, allowing the second power bank to replace it and continue operation. This invention automatically identifies the status of the power bank and controls the portable charging station to move to its location when the power bank's charge level is below a preset level or when the power bank malfunctions. This avoids power outages and improves the reliability of the power supply. Furthermore, by actively moving the portable charging station to the location of users who need to charge or replace their power banks, this invention reduces user waiting time during peak hours and effectively improves the efficiency of power bank replacement. Additionally, by controlling the movement module to move to the location of the first power bank, users are no longer limited to fixed charging stations, increasing the flexibility of power bank replacement. In summary, this invention improves the reliability of power bank supply while increasing the efficiency and flexibility of power bank replacement for users.

It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0024] Figure 1 This is a schematic diagram of a portable charging station provided in an embodiment of the present invention. This embodiment is applicable to charging mobile power supplies, and the portable charging station can be configured in a portable charging system. Figure 1 As shown, the portable charging station includes: at least two portable power banks 110, a control module 120, and a movement module 130. The control module 120 is connected to both the movement module 130 and the portable power banks 110. The at least two portable power banks 110 include a first portable power bank 111 and a second portable power bank 112. Each portable power bank 110 includes a positioning module and a status monitoring module. The positioning module is used to determine the location information of the portable power bank 110. The status monitoring module is used to monitor the status of the portable power bank 110 and generate a status signal. The control module 120 is used to generate a first control signal based on the status signal and location information of the first portable power bank 111. The movement module 130 is used to move to the location of the first portable power bank 111 based on the first control signal.

[0025] Specifically, the portable power bank 110 refers to a portable power supply device typically used to power various electronic devices such as mobile phones, tablets, and laptops. The portable power bank 110 usually has a built-in battery and multiple output ports, enabling it to provide power to devices in the absence of a fixed power source, facilitating user use in mobile environments. The control module 120 refers to an electronic or software module in the portable charging station responsible for managing and coordinating the operation of other components. It can perform functions such as status monitoring of the portable power bank 110, signal processing, and task scheduling of the mobile module 130, ensuring efficient collaborative operation of all parts of the portable charging station. The mobile module 130 refers to the component that enables the portable charging station to move or change location, responsible for moving the portable charging station from one location to another.

[0026] The second power bank 112 refers to the power bank 110 installed on the portable charging station and connected to the control module 120 via electrical and / or wireless connection. The second power bank 112 is in good working order and can quickly take over the operation of the first power bank 111 to power the device. The first power bank 111 connects to the control module 120 via wireless signals such as radio frequency signals or Bluetooth signals. The positioning module refers to the component on the power bank 110 used to determine and track the device's location, typically using a positioning system, wireless network, Bluetooth, or other technologies to obtain the device's geographical location. An exemplary positioning system may include the Global Positioning System (GPS). Location information refers to the location information sent by the positioning module, which may include the longitude and latitude of the power bank 110, or the relative distance information between the power bank 110 and various wireless points within the workspace network of the portable charging station. The status monitoring module refers to the component used to monitor and record the operating status and performance of the power bank 110, and can detect various parameters such as battery level, temperature, cycle count, and charging status. Status signals refer to the status information detected by the status module based on various status parameters of the power bank 110. The control module 120 includes a wireless signal receiving unit, which can receive location information and status signals sent by the first mobile power supply 111. In addition, the location information and status signals of the second mobile power supply 112 can be sent to the control module 120 wirelessly or directly via electrical connection.

[0027] The first control signal refers to the instruction or signal generated by the control module 120 when the first mobile power supply is in an abnormal state. The first control signal may include the status information and location information of the first mobile power supply. For example, when the portable charging station moves to the user's location, it can identify the mobile power supply with the highest battery level in the portable charging station and flash its light to prompt the user to remove the mobile power supply for replacement. After the second mobile power supply 112 is removed, it takes over the charging work of the first mobile power supply 111 to ensure that the power supply to the charging device is uninterrupted.

[0028] In this embodiment of the invention, the power bank 110 can be locked to a portable charging station, allowing only authorized employees to use it, preventing unauthorized use and thus avoiding loss. Locking includes physical locking or disabling charging and discharging functions, which can be freely configured by the administrator. Locking the power bank 110 and associating it with employees has several advantages. First, the power bank 110 can be tracked; second, data on employee power bank usage can be tracked, allowing for planning the deployment of portable charging stations based on employee power needs. For example, more portable charging stations can be deployed in areas with high power consumption, facilitating timely power bank replacements for employees. In emergencies, such as when a portable charging station detects abnormal environmental parameters like high temperature or dense smoke, the power bank 110 will automatically unlock, the station will be moved to a safe area, and the abnormal information will be pushed to the administrator. Regarding the layout of portable charging stations, their locations can be adjusted based on employee usage or density. When a power bank on a portable charging station is idle, the device's power consumption is automatically reduced (e.g., the display screen is dimmed, the device is turned off), extending the power bank's usage time.

[0029] In this embodiment of the invention, the status monitoring module of the first power bank 111 monitors the status of the first power bank 111 and generates a status signal, while the positioning module obtains the location information of the first power bank 111. The status receiving unit 121 and the positioning information receiving unit 123 on the control module 120 can respectively receive the status signal and location information of the first power bank. When the control module 120 detects that the status signal of the first power bank 111 does not meet the normal power supply requirements, for example, when the SOC value of the first power bank 111 is lower than the preset SOC value or the output voltage of the first power bank 111 is lower than the preset voltage, it sends a first control signal to control the moving module 130 to move to the location of the first power bank 111, so that the user can replace the first power bank 111 as needed.

[0030] The technical solution of this invention involves a control module sending a first control signal when an abnormal status signal of the first power bank is detected. This control signal causes the mobile module to move to the location of the first power bank, enabling a second power bank to replace it and continue operation. This invention automatically identifies the status of the power bank and controls the mobile charging station to move to its location when the power bank's charge level is below a preset level, preventing power outages and improving power supply reliability. Furthermore, by actively moving the mobile charging station to the location of users who need to charge or replace their power banks, this invention reduces waiting time during peak hours and effectively improves the efficiency of power bank replacement. Additionally, by controlling the mobile module to move to the location of the first power bank, users are no longer limited to fixed charging stations, increasing the flexibility of power bank replacement. In summary, this invention improves the reliability of power bank supply while increasing the efficiency and flexibility of power bank replacement for users.

[0031] Figure 2 This is a schematic diagram of another mobile charging station provided in an embodiment of the present invention. Based on the above embodiments, refer to... Figure 2 Optionally, the control module 120 includes: a status receiving unit 121, communicatively connected to the first mobile power supply 111, for receiving in real time the power information, temperature information, and cycle count information transmitted by the status monitoring module of the first mobile power supply 111; and a main control unit 122, connected to the status receiving unit 121 and the mobile module 130 respectively, for comparing the power information of the first mobile power supply 111 with the power parameters of the reference model, comparing the temperature information of the first mobile power supply 111 with the temperature parameters of the reference model, and comparing the cycle count information of the first mobile power supply 111 with the cycle count parameters of the reference model. When the power information of the first mobile power supply 111 is less than the power parameters of the reference model, the temperature information of the first mobile power supply 111 is greater than the temperature parameters of the reference model, a fault signal of the first mobile power supply 111 is received, and / or the cycle count information of the first mobile power supply 111 is greater than the cycle count parameters of the reference model, the first control signal is sent to the mobile module 130.

[0032] Specifically, the status receiving unit 121 refers to a component or module within the control module 120 specifically responsible for communicating with the first power bank 111. Its main function is to receive, in real time, information such as power level, temperature, and cycle count from the status monitoring module of the first power bank 111. Power level information refers to the current remaining power of the first power bank 111, usually expressed as a percentage. Temperature information refers to the operating temperature of the first power bank 111, ensuring the device operates within a safe temperature range and avoiding overheating and other safety hazards. Cycle count information refers to the number of charge-discharge cycles completed by the first power bank 111, used to assess the health and lifespan of the battery inside the first power bank 111. Furthermore, the status receiving unit 121 can also communicate with the second power bank 112 to receive, in real time, information such as power level, temperature, and cycle count from the status monitoring module of the second power bank 112. A fault signal refers to the signal transmitted by the first power bank 111 to the main control unit 122 when a fault occurs.

[0033] The main control unit 122 refers to the core component of the control module 120, responsible for coordinating and managing the various components within the control module 120. The reference model power parameter refers to the minimum acceptable power level set for the first power bank 111. The reference model temperature parameter refers to the safe temperature range or threshold set for the first power bank 111. The reference model cycle count parameter refers to the maximum charge / discharge cycle limit set for the first power bank.

[0034] In this embodiment of the invention, the status receiving unit 121 receives in real time the power information, temperature information, and cycle count information transmitted by the first mobile power supply 111. The main control unit 122 is connected to the status receiving unit 121. The main control unit 122 identifies the power information, temperature information, and cycle count information of the first mobile power supply 111, compares the power information of the first mobile power supply 111 with the power parameters of the reference model, compares the temperature information of the first mobile power supply 111 with the temperature parameters of the reference model, and compares the cycle count information of the first mobile power supply 111 with the cycle count parameters of the reference model. When the main control unit 122 detects at least one of the following: the power information of the first mobile power supply 111 is less than the power parameters of the reference model, the temperature information of the first mobile power supply 111 is less than the temperature parameters of the reference model, or the cycle count information of the first mobile power supply 111 is greater than the cycle count parameters of the reference model, it sends a first control signal to the moving module 130, controlling the moving module 130 to move to the position of the first mobile power supply 111.

[0035] Figure 3 This is a schematic diagram of another mobile charging station provided in an embodiment of the present invention. Based on the above embodiments, refer to... Figure 3Optionally, the control module 120 further includes: a positioning information receiving unit 123, a path planning unit 124, and a movement control unit 125; the positioning information receiving unit 123 is communicatively connected to the first mobile power supply 111 and the second mobile power supply 112, and electrically connected to the main control unit 122, for receiving the location information of the first mobile power supply 111 transmitted by the positioning module of the first mobile power supply 111 and the location information of at least one second mobile power supply 112, and uploading it to the main control unit 122; wherein, the second mobile power supply 112 is located in the mobile charging station, and the distance between the first mobile power supply 111 and the mobile charging station is greater than or equal to zero. The path planning unit 124, electrically connected to the main control unit 122, is used to plan a target movement path based on the location information of the first mobile power supply 111, the location information of the second mobile power supply 112, and the map information of the area where the mobile charging station is located; and to monitor obstacles on the target movement path in real time, and correct the target movement path based on the obstacle information; wherein, the map information includes charging location information for charging the mobile charging station. The movement control unit 125 is electrically connected to the path planning unit 124, the movement module 130 and the main control unit 122, and is used to control the movement module 130 to move to the location of the first mobile power source 111 according to the target movement path.

[0036] Specifically, the portable charging station 100 includes a control module 120, a mobility module 130, and a wireless communication module 140. A second portable power bank 112 is placed in the charging slot of the portable charging station 100, and a replaced first portable power bank 111 is placed in the charging slot of the portable charging station 100. The portable charging station 100 can automatically charge the portable power banks placed in the charging slot.

[0037] The main control unit 122 may include a data module and a storage module. On one hand, data acquired by the status receiving unit 121 and the positioning information receiving unit 123 is transmitted to the wireless communication module 140 via the data module. The wireless communication module 140 then uploads this data to the cloud. In other words, the power bank transmits data to the mobile charging station via a physical or wireless connection, thus achieving data communication functionality. On the other hand, the storage module can store the data in the data module. Specifically, the data module within the mobile charging station stores the collected data and power bank information in the storage module. For example, the data module could be a Raspberry Pi.

[0038] It should be noted that the type of wireless communication module 140 is not limited, and the wireless communication module 140 includes, but is not limited to, Bluetooth modules, WIFI networks, cellular networks, IoT modules, LoRa modules, etc. Through the wireless communication module 140, data stored in the storage module or data acquired in real time by the status receiving unit 121 and / or the location information receiving unit 123 can be uploaded to a cloud server and / or cloud storage in the cloud, enabling the mobile charging system to realize the processes and functions of data collection, storage, and analysis. The wireless communication module 140 can be configured to be independently powered by a power system, such as a battery, to ensure that when the power input of the mobile charging station is without power, the wireless communication module 140 maintains a continuous or short-term connection with the cloud, so as to continuously monitor the data and working status of the mobile charging station and prevent the mobile charging station from going offline. For example, the power input of the mobile charging station includes, but is not limited to, the mains power network.

[0039] The data stored in the storage module or the data acquired in real time by the status receiving unit 121 and / or the location information receiving unit 123 can be sent to the user terminal, such as a mobile APP, through the wireless communication module 140 for the user to browse or save the data.

[0040] Users or system administrators can wirelessly access various data from the portable charging station via a terminal, such as a mobile app. This data includes, but is not limited to, data stored in the storage module. In other embodiments, the charging station can also be connected to a mobile device via a wired communication module and a network cable, allowing users to view the data through an app on the mobile device.

[0041] The system data of the mobile charging station can be stored in the cloud or locally. There are no restrictions on the type of storage module; the data type can be selected according to needs. Data in the storage module can be set to be refreshed and cleared periodically to free up storage space, or stored permanently, with a reminder to update when storage space is insufficient. The type of storage module is not limited. For example, the storage module can be a memory mounted on a circuit board or an external memory card. This configuration facilitates data management, protects user privacy, and meets the administrator's requirements for the confidentiality of system user information.

[0042] Furthermore, the portable charging system can collect user usage habits, as the interfaces on portable charging stations, i.e., the interfaces configured on power banks, may vary. By collecting user habit data, the system can determine, for example, that area A has the most users with USB-C interfaces. It can then automatically distribute charging stations with more USB-C interfaces within that area. This algorithmic allocation process effectively improves the utilization rate of charging stations while meeting user needs. Based on this, administrators can assign which portable charging station to which location, allowing them to automatically move to their corresponding positions, thus improving the overall system and equipment utilization. Moreover, users can view the specific locations of portable charging stations and power banks through a terminal app.

[0043] The positioning information receiving unit 123 refers to the component in the control module 120 used to receive the location information of the first mobile power supply 111 and the second mobile power supply 112, and upload this information to the main control unit 122. The path planning unit 124 refers to the component in the control module 120 used to plan a movement path based on the location information of the first mobile power supply 111 and the second mobile power supply 112, as well as map information. Furthermore, the path planning unit 124 can monitor obstacles on the path in real time, and correct the target movement path when obstacles are detected, ensuring the path avoids obstacles. The target movement path refers to the movement route of the mobile module 130 planned by the path planning unit 124 based on the location information of the first mobile power supply 111 and the second mobile power supply 112, as well as map information. For example, the target movement path could be from the location of the second mobile power supply 112 to the location of the first mobile power supply 111. The map information refers to comprehensive data including geographic information of the mobile charging station 100 and its surrounding environment, as well as charging location information for the mobile charging station 100. Obstacles refer to obstacles detected on the movement path, such as buildings, people, and vehicles, that could affect the normal movement of the mobile module 130. The motion control unit 125 refers to the control component that controls the actual motion module 130 to move according to the motion path provided by the path planning unit 124.

[0044] In this embodiment of the invention, the positioning information receiving unit 123 can receive the positioning information sent by the first mobile power supply 111 and the second mobile power supply 112, and then upload the positioning information of both to the main control unit 122. Based on the status information received by the status receiving unit 121 and the positioning information received by the positioning information receiving unit 123, the main control unit 122 controls the path planning unit 124 to plan the target movement path of the movement module 130, and the movement control unit 125 controls the movement of the movement module 130 according to the target movement path.

[0045] The technical solution of this invention involves receiving status information of a first mobile power supply through a status receiving unit, and receiving location information of both a first and a second mobile power supply through a positioning information receiving unit. The main control unit then controls a path planning unit to plan a target movement path based on the status information, location information, and location information of the first and second mobile power supplies, and sends this path to a movement control unit. The movement control unit then controls the movement of the mobile module. This invention enables a mobile charging station to automatically detect the status of the first mobile power supply and actively move to its location when its status is poor. This allows users to replace the first mobile power supply with a second mobile power supply, ensuring a continuous power supply for user devices and effectively improving the efficiency and flexibility of charging mobile power supplies.

[0046] Based on the above embodiments, refer to Figure 3 Optionally, the mobile charging station further includes: a wireless communication module 140; the wireless communication module 140 is electrically connected to the control module 120, and is used to upload the status information of the first mobile power supply 111, the location information of the first mobile power supply 111, and the location information of the second mobile power supply 112 to the cloud server 150, and to receive control commands from the mobile terminal 160 and send them to the control module 120, the control commands being used to control the control module 120 to generate a first control signal; wherein, the mobile terminal 160 and the cloud server 150 perform data interaction.

[0047] Specifically, the wireless communication module 140 refers to a hardware component used to realize wireless data transmission between devices. The cloud server 150 refers to a remote data storage and processing server capable of storing location information, usage records, and other data from multiple mobile charging devices. The mobile terminal 160 refers to a portable device used by a user to access system information and control the device, such as a smartphone or tablet. The control command refers to the control command sent by the mobile terminal 160 to the control module 120 based on information from the cloud server 150. After receiving the control command, the control module 120 issues a first control signal to control the mobile module to move from the location of the second mobile power source 112 to the location of the first mobile power source 111. For example, the mobile terminal 160 can be a smartphone, and the user can send control commands to the wireless communication module 140 via an app on the smartphone, commanding the mobile charging station to move.

[0048] Furthermore, the charging station can connect to mobile terminals, allowing users or administrators to wirelessly view various data about the charging station, including but not limited to data stored in the storage module and data from each portable power bank within the station, such as location, charging / discharging status, battery level, and temperature. When the charging station detects abnormal environmental parameters such as high temperature or dense smoke, it will automatically unlock the portable power banks and send an alarm message to the user's or administrator's mobile terminal; it will also control the portable charging station to a safe area.

[0049] Users or administrators can also automatically deliver power banks to designated locations via a mobile app, and alert users when a portable charging station approaches. Users can also actively call for portable charging stations via the app. A user can actively call for any portable charging station via the app, or any model of power bank from a target portable charging station via the app. Simultaneously, the mobile terminal can monitor the location of portable charging stations, the status of power banks on the stations, the removal of power banks from the stations, and the charging percentage of each power bank on the stations.

[0050] In this embodiment of the invention, the mobile terminal 160 and the cloud server 150 can interact with each other. The mobile terminal 160 can send a control command to the wireless communication module 140 according to the information of the cloud server 150. The wireless communication module 140 sends the control command to the main control unit 122. The main control unit 122 generates a first control signal according to the control command and controls the mobile module 130 to move to the position of the first mobile power source.

[0051] In one alternative implementation, multiple mobile charging stations communicate with the cloud; multiple mobile charging stations communicate with a terminal; and the cloud communicates with the terminal.

[0052] During operation, the mobile charging station provides charging and discharging management functions to at least one portable power bank awaiting charging. The portable power bank transmits data to the mobile charging station via physical and / or wireless connections, enabling data transmission. The mobile charging station then uploads the collected data to the cloud, enabling data communication.

[0053] The cloud platform is equipped with cloud servers and cloud storage. Terminals are terminal devices or applications (APPs) with information processing capabilities. User roles for terminals include: system operators, system administrators, and consumer users. A system operator can be comprised of one or more companies. For example, multiple mobile charging stations deployed in a shared office space can be simultaneously designated as system operators, managing all mobile charging stations within that space. System administrators are the providers of the mobile charging stations and / or cloud service providers. System administrators can configure and manage the functions of the mobile charging stations and their access permissions according to actual needs. Consumer users can be any user within a limited area and under limited usage conditions. They can use information processing terminals, including mobile APPs, to access and configure the functions of the mobile charging stations and the power banks waiting to be charged.

[0054] During operation, the mobile charging station provides charging and discharging management functions to at least one portable power bank awaiting charging. The portable power bank transmits data to the mobile charging station via physical and / or wireless connections, enabling data transmission. The mobile charging station uploads the collected data to the cloud, enabling data communication.

[0055] Based on the above embodiments, refer to Figure 3 Optionally, the moving module 130 further includes a motor 131 and at least one drive wheel 132; the motor 131 is electrically connected to the moving control unit 125 and the drive wheel 132 respectively, and is used to drive the drive wheel 132 to rotate under the control of the moving control unit 125, and the drive wheel 132 is used to drive the moving module 130 to move.

[0056] Specifically, motor 131 refers to a device that converts electrical energy into mechanical energy. Under the control of the motion control unit 125, motor 131 is responsible for driving the rotation of drive wheel 132. Drive wheel 132 is a wheel directly connected to motor 131, which can drive the driven wheel to rotate, thereby supporting the movement of motion module 130.

[0057] In this embodiment of the invention, the motion control unit 125 controls the motor 131 to rotate, and the motor 131 drives the drive wheel 132 to rotate, thereby moving the motion module 130.

[0058] The technical solution of this invention achieves efficient data interaction through a wireless communication module, a mobile terminal, and a cloud server, thereby improving user experience and the intelligence level of the system.

[0059] This invention provides a portable charging station that communicates wirelessly with its workspace network and a cloud server. The cloud server sends path instructions to the portable charging station based on full-space map data, enabling the station to precisely move to each user's location. The control module of the portable charging station receives the instructions and executes the actions. During movement, the portable charging station can connect with various wireless points to confirm its location information. The cloud server can identify location information and provide preventative and corrective feedback.

[0060] The cloud server receives and analyzes the status information sent by each power bank, and compares this status information with the baseline model parameters of the baseline status data model. For example, the baseline model parameters may include baseline model power parameters. For instance, when the power bank's power level is lower than the baseline model power parameters, the cloud server, through path analysis and the availability of portable charging stations, sends a battery swapping instruction to the target portable charging station, which then proceeds according to the instruction.

[0061] For example, the baseline model parameters may include baseline model state parameters. For instance, when the power bank's state information deviates from the baseline model state parameters, the power bank or cloud server will issue an alarm, and the power bank or cloud server can promptly issue various alarm commands.

[0062] The mobile charging station provided in this invention fully utilizes wireless networks and cloud servers, resulting in fast response speeds and timely determination and feedback of battery swapping status, as well as the issuance and feedback of battery swapping commands. This mobile charging station employs a method of comparison with a benchmark data model, reducing the need for manual determination of the power bank's status and the environment, thus minimizing human error and labor costs. The mobile charging station utilizes various data models, including a benchmark data model used by the cloud server to analyze the path, location, and availability of a designated target mobile charging station, a benchmark determination model for power bank and environmental information, and a system battery swapping product logic model. This avoids the need for users to manually walk and search for charging stations; the mobile charging station autonomously moves to find the user, greatly improving convenience and power efficiency. The mobile charging station provided in this invention has a high degree of automation and integration, minimizing human intervention.

[0063] Figure 4 This is a flowchart illustrating a mobile charging station control method provided in an embodiment of the present invention. Figure 4 As shown, the method includes: S210. Obtain the location information of the first mobile power bank through the positioning module on the first mobile power bank, obtain the location information of the second mobile power bank through the positioning module on the second mobile power bank, or identify the location information of the second mobile power bank through the connection signal of the portable charging station, and obtain the status signal of the first mobile power bank through the status monitoring module on the first mobile power bank.

[0064] In this embodiment of the invention, the status signal of the first mobile power source can provide status information of the first mobile power source, such as battery level, temperature, and cycle count. The location information of the first mobile power source and the location information of the second mobile power source can provide the starting point and ending point location information of the mobile module.

[0065] S220. The control module generates a first control signal based on the status signal of the first mobile power supply, the location information of the first mobile power supply, and the location information of the second mobile power supply.

[0066] In this embodiment of the invention, the control module acquires the status signal of the first mobile power supply, compares the status signal of the first mobile power supply with the status parameters of a reference model, and generates a first control signal based on the comparison result. The status signal of the first mobile power supply may include power information, temperature information, and cycle count information of the first mobile power supply. The status parameters of the reference model may include reference model power parameters, reference model cycle count parameters, and reference model temperature parameters.

[0067] The control module compares the power level of the first mobile power source with the power level parameter of the reference model, the temperature parameter of the first mobile power source with the temperature parameter of the reference model, and the number of cycles of the first mobile power source with the number of cycles of the reference model. When the power level of the first mobile power source is less than the power level parameter of the reference model, the temperature parameter of the first mobile power source is greater than the temperature parameter of the reference model, or the number of cycles of the first mobile power source is greater than the number of cycles of the reference model, the control module generates a first control signal based on the position information of the first and second mobile power sources to control the movement of the mobile module.

[0068] S230. The mobile module moves to the position of the first mobile power supply according to the first control signal.

[0069] In this embodiment of the invention, the first control signal includes information such as the location information of the first power supply and the location information of the second power supply. After receiving the first control signal, the mobile module moves to the location of the first power supply. The control module receives the signal from the mobile module that it has moved to the location of the first power supply, allowing the user to remove the second power supply so that the second power supply can replace the first power supply and continue to power the user's device.

[0070] The technical solution provided by this invention involves a control module sending a first control signal when it detects an abnormality in the status signal of the first power bank, controlling the mobile module to move to the position of the first power bank, so that the second power bank can replace the first power bank and continue to work. This effectively improves the efficiency and flexibility of charging the power bank, while also making it convenient for users to use, and realizing flexible charging of the power bank and continuous power supply to the device.

[0071] Based on the above embodiments, optionally, after the mobile module moves to the position of the first mobile power source according to the first control signal, the method further includes: controlling the mobile module to move to the charging position of the charging station.

[0072] In this embodiment of the invention, the charging location of the charging base station can be obtained from map information. Upon receiving a first mobile power bank with insufficient power, the mobile charging station can automatically move to the charging location of the charging base station, automatically connect, and charge the first mobile power bank with insufficient power. With the continuous issuance of charging commands, the mobile charging station frequently carries mobile power banks with varying capacities to provide battery swapping services to users. During this process, the capacity of the mobile power banks may differ; therefore, to maximize the power efficiency of the mobile charging system, the charging strategy of the mobile charging station can be set by the administrator. For example, during working hours, the mobile charging station is always in fast charging mode; once a mobile power bank is placed on the mobile charging station, it can be quickly charged immediately, meeting the high turnover rate within the power consumption space during working hours.

[0073] For example, during weekends, portable charging stations are set to a semi-dormant state. When more than half of the power banks are not fully charged, the portable charging station will switch to charging mode. This charging strategy can be configured by the administrator to match the operating modes and power consumption habits within the charging space.

[0074] Charging base stations are typically base station equipment that is constantly connected to mains power. The number of charging base stations within the power-consuming space can be the same as or different from the number of portable charging stations. For example, the number of charging base stations can be more than the number of portable charging stations, the number of charging base stations can be less than the number of portable charging stations, or the number of charging base stations can be equal to the number of portable charging stations.

[0075] In some implementations, when the number of charging base stations within the power-consuming space is greater than or equal to the number of mobile charging stations, the mobile charging stations will always be charging at a charging base station when they are not moving outside. The charging base stations offer both contact charging and wireless inductive charging methods to adapt to different charging needs. Contact charging base stations are equipped with standardized charging interfaces, such as DC fast charging interfaces and Type-C interfaces.

[0076] Once the mobile charging station is in place, it precisely connects with the standardized charging interface of the contact charging base station via its own interface, establishing a physical conductive path. The contact charging base station then supplies power to the mobile charging station, while simultaneously providing real-time feedback on charging voltage, current, and power status to ensure safe and stable charging.

[0077] The wireless inductive charging base station has a built-in inductive transmitting coil, and the portable charging station is equipped with a corresponding inductive receiving coil, eliminating the need for physical interface connections. Once the portable charging station enters the sensing range of the wireless inductive charging base station and completes positioning calibration, the base station transmits electrical energy to the station via electromagnetic induction. The wireless inductive charging base station is suitable for scenarios where avoiding tangled wiring and requiring high interface protection are necessary. Furthermore, it supports short-distance fine-tuning of its position during charging without affecting charging continuity.

[0078] In some implementations, when the number of charging base stations is less than the number of mobile charging stations, at least one fully charged mobile charging station may be parked in a waiting area outside the charging base stations, without any limitation.

[0079] Figure 5 A flowchart illustrating another mobile charging station control method provided by an embodiment of the present invention. Based on the above embodiments, refer to... Figure 5 Optionally, the control method for the mobile charging station includes: S310. Obtain the location information of the first mobile power bank through the positioning module on the first mobile power bank, obtain the location information of the second mobile power bank through the positioning module on the second mobile power bank, or identify the location information of the second mobile power bank through the connection signal of the portable charging station, and obtain the status signal of the first mobile power bank through the status monitoring module on the first mobile power bank.

[0080] S320. The control module generates a first control signal based on the status signal of the first mobile power supply, the location information of the first mobile power supply, and the location information of the second mobile power supply.

[0081] S330: The path planning unit plans the target movement path of the mobile module based on the location information of the first mobile power source, the location information of the second mobile power source, and the map information of the area where the mobile charging station is located.

[0082] In this embodiment of the invention, the target movement path is planned by the path planning unit, which can reduce the movement time of the mobile module between the charging station and the power source, and ensure that the mobile module reaches the location of the first mobile power source in the shortest possible time, thereby improving efficiency.

[0083] S340. The main control unit controls the moving module to start moving according to the target moving path.

[0084] In this embodiment of the invention, the main control unit instructs the moving module to start moving according to the previously planned target moving path, ensuring that it travels along the predetermined route.

[0085] S350. During the movement of the mobile module, the path planning unit monitors the environmental information on the target movement path in real time. If there are obstacles on the target movement path, the target movement path is corrected to avoid the obstacles.

[0086] In this embodiment of the invention, the path planning unit continuously monitors the environmental information along the mobile module's path to ensure timely identification of potential obstacles. If an obstacle is detected, the mobile charging station can automatically correct its path to ensure the mobile module safely bypasses the obstacle, avoiding collisions and damage, thereby effectively preventing accidents, improving operational safety, and protecting the safety of equipment and personnel.

[0087] Based on the above embodiments, optionally, the mobile charging station control method further includes: uploading the status information of the first mobile power supply, the location information of the first mobile power supply, the location information of the second mobile power supply, and the target movement path to a cloud server via a wireless communication module; receiving control commands from a mobile terminal via a wireless communication module and sending them to a control module; and generating a first control signal by the control module according to the control commands.

[0088] In this embodiment of the invention, the status information and location information of the first mobile power supply, as well as the information of the second mobile power supply, are uploaded to a cloud server via a wireless communication module, ensuring real-time data updates and centralized management. The data uploaded to the cloud server can be accessed by mobile terminals, enabling information sharing and facilitating real-time monitoring and management of the mobile power supply's operating status by administrators. Furthermore, the wireless communication module can receive control commands from the mobile terminal and send them to the control module, allowing users to remotely control the mobile module to move towards the location of the first mobile power supply, improving the flexibility of the mobile charging station.

[0089] In one alternative implementation, for example, in an office building, the administrator sets up 10 mobile charging stations, each equipped with 5 different models of portable power banks (Type A, Type B, Type C, Type D, and Type E), and there are 10 charging base stations.

[0090] One possible application scenario: After employee A arrives at their workstation, their location information is identified via a mobile app. For example, employee A's workstation location is identified by swiping their card using the mobile app on their mobile device. The app then requests a Type A power bank. Upon receiving the request, the cloud server identifies a portable charging station equipped with a Type A power bank. The portable charging station responds to the request and moves to employee A's workstation, eliminating the need for employee A to search for a charging station. Another possible application scenario: After entering the office building, employee B passes a portable charging station, randomly picks up a Type C power bank from it, and takes it to their workstation. Employee B's workstation location is identified by swiping their card using the mobile app on their mobile device.

[0091] After a first preset time period, such as 0.5 hours or 1 hour, the battery levels of both the Type A power bank used by employee A and the Type C power bank used by employee B fall below their baseline model battery parameters. Both power banks automatically send battery swapping instructions to the cloud server. The nearest mobile charging station equipped with a Type A power bank automatically moves to employee A's workstation, reminding employee A to swap batteries, and the swap is completed. Similarly, the nearest mobile charging station equipped with both Type A and Type C power banks automatically moves to employee B's workstation, reminding employee B to swap batteries, and the swap is completed. Alternatively, the nearest mobile charging station equipped with both Type A and Type C power banks simultaneously sends reminders to both employee A's and employee B's workstations, respectively, to swap batteries, and the swaps are completed.

[0092] As different employees have different needs, the mobile charging station may move around in space. After completing the battery swap, it can automatically find the nearest charging station to recharge.

[0093] Furthermore, portable charging stations can directly identify power bank swapping requests. They can also record employees' preferences for power bank models. By accumulating this data, the portable charging station can construct an employee power demand data model. Based on this model, the portable charging station can autonomously learn and update it, resulting in an updated model that better suits the power consumption habits of all employees, further improving the overall power efficiency of the office building.

[0094] It should be noted that the employee electricity demand data model is deeply integrated into the delivery logic of the mobile charging station. This allows the mobile charging system to make scheduling decisions by fully considering real-time factors such as spatial location, the status of the mobile charging station, and model matching. It can also predict and prioritize matching mobile power bank models that match user habits based on historical data, thus achieving an upgrade from "passive response" to "active prediction" and comprehensively improving the accuracy of power supply services and the power efficiency of the entire space.

[0095] In one optional implementation, based on the above embodiments, for example, large exhibition halls or conference centers often feature movable information display screens or interactive screens, which typically require continuous power to operate. Traditional wiring methods not only restrict screen movement but also make it difficult to quickly find charging points after movement, and also pose a risk of power outages. The movable charging station provided by this invention can provide active power supply in this scenario. The movable charging station provided in the above embodiments of this application is used to supply power to the aforementioned movable information display screens or interactive screens.

[0096] For example, a threshold can be set, such as 30% of the total battery power. When the power bank used by the portable screen drops to the set threshold, the positioning module built into the power bank sends a low battery signal and the power bank's real-time location to the control module of the portable charging station. After receiving the low battery signal and the power bank's real-time location, the path planning unit of the portable charging station plans a target movement path based on the location information of the portable screen. The control module controls the movement module to move to the vicinity of the portable screen according to the target movement path. After that, the portable charging station wirelessly prompts the staff to complete the power bank replacement. After completion, the portable charging station returns to the charging area to stand by or returns to the charging base station to replenish its power. The portable screen continues to work normally, ensuring the continuity and user experience of the portable screen.

[0097] Another alternative implementation, based on the above embodiments, exemplarily speaking, addresses areas with inconvenient power connections, such as remote rural clinics, temporary medical shelters after disasters, field rescue sites, and temporary isolation wards in hospitals. Specialized medical equipment such as mobile monitors, portable ultrasound devices, and mobile infusion pumps cannot rely on fixed power lines for continuous operation and must be powered entirely by mobile power sources. In these areas, not only are stable mains power interfaces lacking, but traditional fixed charging stations are also completely unavailable. Furthermore, mobile power sources have limited battery life, and if the power is about to run out or the temperature becomes abnormal, these specialized medical devices are prone to shutdown, severely impacting the normal operation of medical and rescue work. The portable charging station provided in the above embodiments of the present invention can charge the mobile power sources of specialized medical equipment such as mobile monitors, portable ultrasound devices, and mobile infusion pumps, specifically adapting to such scenarios and providing stable and timely power support for medical equipment.

[0098] For example, mobile monitors are powered by a portable power bank. When the power bank is about to run out of power or experiences abnormal temperature, medical staff can send a power bank status alarm and the power bank's real-time location to the portable charging station via a mobile terminal. Upon receiving the power bank status alarm and real-time location information, the portable charging station immediately enters a high-priority task queue. A high-definition terrain map of the area is simultaneously loaded via the path planning module, and a dynamic path planning algorithm is used to plan the shortest and safest movement route, i.e., the target movement path. The control module controls the mobile module to move to the target location according to the target movement path and notifies the user, such as medical staff, that the portable charging station has arrived via the wireless communication module. The user can then promptly replace the power bank, ensuring uninterrupted operation of devices such as mobile monitors. After the battery swap, the portable charging station returns to the charging base station for recharging and surface disinfection. Charging data is also synchronized to the corresponding medical device management system via a cloud server. This medical device management system not only reduces the equipment management burden for medical staff and other users but also ensures emergency power supply for critical medical equipment, improving medical safety and efficiency.

[0099] Another alternative implementation, exemplified by this example, addresses the issue of users' portable electronic devices such as mobile phones, cameras, drones, and outdoor lighting equipment easily running out of power in scenarios like outdoor music festivals, campsites, or outdoor construction areas. Traditional power banks require users to carry them with them, and there are no fixed charging points outdoors, resulting in scattered charging resources. Furthermore, outdoor environments present challenges such as complex terrain, unpredictable weather, and the lack of stable network connectivity. This embodiment provides charging services to address the mobility and environmental complexity of outdoor scenarios.

[0100] For example, mobile charging stations can be deployed outdoors and solar-powered systems activated, synchronizing outdoor map data with satellite positioning. The status monitoring module within the mobile charging station continuously monitors various parameters of the power bank and receives charging requests initiated by users. Users can search for nearby mobile charging stations, their remaining battery level, and available interface types via their mobile devices. A scheduled charging function is supported; users in urgent situations can mark an emergency, and the mobile charging station prioritizes responding based on these marked emergency statuses. When the mobile charging station receives a charging request from user A, it controls its movement module to move to user A's location and notifies the user to retrieve the power bank via their mobile device. The mobile charging station monitors the parameters of the retrieved power bank in real time. When the power level of the retrieved power bank falls below a baseline model parameter (i.e., a set threshold), the mobile charging station actively moves to the location of the retrieved power bank and reminds the user to swap batteries. After completing the swap or charging of the current power bank, the mobile charging station moves to the next requested location or uses solar panels for replenishment. When a mobile charging station's own battery level falls below a threshold, such as 20% of its total battery capacity, it will proactively travel to a charging base station for recharging. Administrators can also remotely view the distribution locations, recharging efficiency, and fault information of mobile charging stations via a cloud server, facilitating remote scheduling and maintenance.

[0101] Figure 6 This is a schematic diagram illustrating an office use scenario for a portable charging station, as provided in an embodiment of the present invention. The movement path of the portable charging station 100 is as follows: Figure 6 As shown by the dashed line, when the power of the first mobile power bank 111 located at the workstation is detected to be insufficient, the portable charging station 100 is controlled to move to the workstation. After the user at the workstation removes the fully charged second mobile power bank and places the first mobile power bank 111 back on the portable charging station 100, the portable charging station 100 can automatically return to the base station for charging.

[0102] Based on the same inventive concept, this embodiment provides a control method for a portable charging system. The control method for the portable charging system provided in this embodiment includes: Step 1: When the main control unit of the cloud server or the mobile charging station detects that the power of the first mobile power source located at the target location is insufficient, the main control unit or the cloud server controls the matching mobile charging station to move to the target location according to the planned path.

[0103] Step 2: After the user at the target location removes the fully charged second power bank and places the first power bank back into the portable charging station, the portable charging station automatically confirms the placement status and identity information of the first power bank through inductive identification technology, and uploads a "placement complete" signal to the main control unit or cloud server.

[0104] Step 3: The main control unit or cloud server, based on the received "placement complete" signal, schedules the mobile charging station to return to the charging base station along the planned path.

[0105] Step 4: The mobile charging station charges at the charging base station.

[0106] Optionally, based on the above embodiments, after step three, whereby the main control unit or cloud server schedules the mobile charging station to return to the charging base station along the planned path according to the received "placement complete" signal, the method may further include: During the process of the mobile charging station returning to the charging base station, if the mobile charging station receives or detects any target location again, it will dynamically interrupt the current task of returning to the charging base station according to the task priority, and respond to the power replenishment needs of the mobile power supply at the high-priority target location.

[0107] Optionally, based on the above embodiments, the charging process of the mobile charging station at the charging base station may further include: During the charging process from the charging base station to the mobile charging station, the mobile charging station continuously monitors its own charging status and external task requests.

[0108] If the monitoring time exceeds the second preset time and the mobile charging station does not receive the target location, the mobile charging station will maintain the charging state and switch to sleep mode during the charging process.

[0109] For example, Figure 7 A flowchart illustrating another mobile charging station control method provided by an embodiment of the present invention. Based on the above embodiments, refer to... Figure 7 The control method for the mobile charging station provided in this embodiment includes: S701. When the main control unit or cloud server detects that the first mobile power supply 111 at the target location has insufficient power, the main control unit or cloud server controls the mobile charging station 100 to move to the target location. The target location is, for example, a workstation.

[0110] S702. After the user at the target location removes the fully charged second power bank and places the first power bank 111 back on the portable charging station 100, the portable charging station automatically confirms the placement status and identity information of the power bank through inductive identification technology, and uploads a "placement complete" signal to the main control unit.

[0111] S703. After receiving the "placement complete" signal, the main control unit immediately dispatches the mobile charging station to return to the charging base station along the optimized path.

[0112] As fixed infrastructure, charging base stations are typically continuously connected to the mains power supply to ensure a stable and continuous power supply. Their primary function is to provide centralized and secure power replenishment for mobile charging stations.

[0113] S704. During the process of the mobile charging station returning to the charging base station, if the mobile charging station detects any target location again, such as the mobile power supply at the workstation having insufficient power, it can dynamically interrupt the current return to the charging base station task according to the task priority and prioritize responding to the power replenishment needs of the high-priority target location.

[0114] The S705 mobile charging station can charge at the charging base station.

[0115] S706. During the charging process at the charging base station, the mobile charging station continuously monitors its own charging status and external task requests. If the mobile charging station does not receive a power demand from the target location, such as a workstation, after a second preset time has elapsed, the mobile charging station will maintain the charging state and switch to sleep mode during the charging process to save energy.

[0116] In an optional implementation, after step S705 of the above embodiment, the method may further include: S707, the mobile charging station switches to a sleep mode, which can activate an overcharge protection mechanism to continuously monitor the health status of the mobile charging station's own battery and the mobile power supply it carries, effectively avoiding the risk of thermal runaway or performance degradation caused by prolonged charging.

[0117] In another optional implementation, after step S705 of the above embodiment, it may further include: S708, during the charging process of the mobile charging station, the battery management system of the mobile charging station continuously monitors the battery status and provides real-time feedback on the charging progress.

[0118] Another alternative implementation involves a cloud server capable of multi-task concurrent processing and learning. This allows it to predict high-frequency target locations, such as the power consumption periods of workstations, based on historical task data, and pre-arrange mobile charging stations to be on standby. When multiple target locations, such as workstations, simultaneously initiate power requests, the main control unit of the mobile charging station intelligently allocates the path execution order of the mobile charging stations, optimizing the overall system energy efficiency and response speed.

[0119] The technical solution of this invention plans the target movement path of the mobile module through a path planning unit, and monitors the environmental information along the target movement path in real time during the movement of the mobile module, correcting the route in a timely manner to avoid the mobile module encountering obstacles. This invention can enhance the flexibility and safety of mobile charging stations, and also improve charging efficiency and reduce user waiting time.

[0120] In another optional implementation, based on the above embodiments, the mobile charging station can be equipped with a fault detection system. The fault detection system is used to monitor information of critical components in real time. A critical component is, for example, the battery. When the fault detection system of the mobile charging station detects abnormalities in the critical parameters of a critical component, such as battery overheating, a fault signal is generated by the main control unit. The fault signal is sent to the administrator via multi-mode wireless communication. For example, during charging, if the fault detection system of the mobile charging station detects that the battery temperature exceeds a reference model temperature parameter, such as a set 50°C, the main control unit of the mobile charging station controls the charging to stop and sends a fault signal. Furthermore, when the fault signal is a battery overheating fault, the mobile charging station can automatically move to a safe area to prevent further overheating risks.

[0121] Another alternative implementation involves integrating various environmental sensors into the portable charging station. For example, a temperature sensor can be installed to monitor the internal battery temperature, the temperature of the mounted power bank, and the external ambient temperature. Temperature information includes the internal battery temperature, the temperature of the mounted power bank, and the external ambient temperature. Alternatively, a humidity sensor can be installed to detect humidity levels within the portable charging station, preventing excessive humidity from causing circuit malfunctions such as short circuits. Finally, a smoke sensor can be installed to detect fire or smoke risks.

[0122] The control unit can set corresponding baseline model parameter thresholds, such as an internal temperature of >60°C and an external smoke concentration of >5%. When the corresponding sensing parameters detected by the sensors reach the baseline model parameter thresholds, the mobile charging station is automatically moved to a predefined safe area. During the relocation process, the mobile charging station continuously sends status updates via wireless communication, including new location information and environmental sensing parameters, facilitating tracking by administrators.

[0123] For example, if smoke is detected nearby during battery swapping or charging at a mobile charging station, it immediately stops charging or swapping, sends an "environmental hazard" alarm to the administrator via wireless communication, and automatically navigates to a predefined safe area. Additionally, the mobile charging station can activate warning lights and audible alarms to alert nearby personnel. If the portable power bank or its own battery overheats, the mobile charging station will prioritize moving to a well-ventilated area and reduce power output to prevent thermal runaway. The mobile charging station can continuously send status updates, including new location information and environmental sensor parameters, allowing administrators to remotely monitor it via a cloud server. When the temperature drops below the baseline model's temperature parameters, the mobile charging station resumes operation.

[0124] This invention also provides a mobile charging system, including a mobile charging station provided in any embodiment of this invention, capable of executing the mobile charging station control method provided in any embodiment of this invention, and possessing corresponding functional modules and beneficial effects for executing the mobile charging station control method.

[0125] Optionally, based on the above embodiments, the portable charging system may further include: A cloud server is communicatively connected to the portable charging station. When the cloud server or the main control unit of the portable charging station detects that the first portable power bank at the target location has insufficient power, it controls the matching portable charging station to move to the target location according to a planned path. After the user at the target location removes the fully charged second portable power bank and puts the first portable power bank back into the portable charging station, the portable charging station automatically confirms the placement status and identity information of the first portable power bank through inductive identification technology, and uploads a "placement complete" signal to the main control unit or the cloud server.

[0126] The main control unit or cloud server is used to schedule the mobile charging station to return to the charging base station along the planned path based on the received "placement complete" signal.

[0127] Optionally, based on the above embodiments, the portable charging system may further include: The charging base station is used to charge the mobile charging station.

[0128] Optionally, based on the above embodiments, the mobile charging station is further configured to, during the process of the mobile charging station returning to the charging base station, dynamically interrupt the current task of returning to the charging base station according to the task priority when the mobile charging station receives or detects any target location again, and respond to the power replenishment needs of the mobile power supply at the high-priority target location.

[0129] Optionally, based on the above embodiments, the mobile charging station is further configured to continuously monitor its own charging status and external task requests during the charging process from the charging base station to the mobile charging station; if the monitoring time exceeds a second preset time and the mobile charging station does not receive the target location, the mobile charging station will maintain the charging state and switch to sleep mode during the charging process.

[0130] It should be understood that the various forms of processes shown above can be used, with steps reordered, added, or deleted. For example, the steps described in this invention can be executed in parallel, sequentially, or in different orders, as long as the desired result of the technical solution of this invention can be achieved, and this is not limited herein.

[0131] The specific embodiments described above do not constitute a limitation on the scope of protection of this invention. Those skilled in the art should understand that various modifications, combinations, sub-combinations, and substitutions can be made according to design requirements and other factors. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this invention should be included within the scope of protection of this invention.
