The number of electric vehicles is increasing, and accordingly, the demand for electric vehicle charging and energy supplementing equipment is also increasing.

[0003] Battery swapping stations, as a kind of fast energy supplementing facilities, are increasingly supported by users and policies. Battery swapping stations can make full use of time to fully charge the batteries in the station. In the case that all or most of the batteries in the station are fully charged, the demand for charging in the station is reduced. At this time, the charging system or the power capacity of the station can be used for charging electric vehicles.

At this time, the charging system or the power capacity of the station can be used for charging electric vehicles.

[0202] The current common practice is to build station piles together, and independently arrange charging piles with the same capacity near the battery swap station. Although this solves the problem of power capacity sharing, it is a redundant arrangement of charging equipment and has poor economy. Alternatively, although power distribution is made according to the power consumption situation, the priority of the charging battery is given priority, and the effect of power sharing is poor.

[0203] In order to solve the problem of poor power sharing effect of the charging and battery swap station, the present application provides a charging management method. The charging and battery swap station includes X charging terminals and Y charging modules, and X>Y. At least part of the charging modules are connected with the plurality of charging terminals. The charging management method includes the following steps: when receiving the charging request of the charging terminal, it is confirmed whether there is an available charging module; when there is an available charging module, the available charging module is switched to the charging terminal requesting charging. The available charging module includes an idle charging module and a switchable charging module.

[0204] The technical solution of the present application can timely switch the available charging module to the charging terminal requesting charging when there is an available charging module, better perform power sharing of the charging and battery swap station, realize time-sharing multiplexing of the charging module between different charging terminals, and reduce the idle rate of the charging module. In addition, it can also reduce and avoid the redundant setting of the equipment of the charging and battery swap station, improve the economy of the charging and battery swap station, and make the charging and battery swap station have a smaller floor area.

[0205] Exemplary charging and swapping station

[0206] First, the charging and battery swap station provided by the present application is described in combination with FIG. 1 and FIG. 2 , the line with double arrows represents the communication connection, and the line without arrow represents the physical connection. FIG. 1

[0207] As shown in FIG. 1 ​As shown, the charging and battery swapping station includes a battery swapping unit, a plurality of charging terminals 14, a plurality of charging modules 12, a master control system 10 and a power distribution unit 13. The battery swapping unit includes a battery swapping mechanism 16 for swapping batteries for a vehicle to be charged, and the charging terminals 14 are used for charging the vehicle or the battery. The power distribution unit 13 has a first input end 131 and a first output end 132, and the first output end 132 is physically connected to the charging terminals 14. The charging module 12 has a second input end connected to a power grid and a second output end 121 physically connected to the first input end 131, and the number of the charging modules 12 is less than the number of the charging terminals 14. The master control system 10 is communicatively connected to the power distribution unit 13, the charging modules 12 and the charging terminals 14, and is configured to control the power distribution unit 13 to distribute power based on a charging request of the charging terminal 14. In this application, the charging module is an AC / DC module group, each AC / DC module group includes at least one AC / DC module, and the charging terminal 14 includes a vehicle charging pile 141 and a battery charging bin 142.

[0208] In this way, the master control system 10 of the charging and battery swapping station can communicate with the power distribution unit 13, the charging modules 12 and the charging terminals 14, and when there is an available charging module 12, the available charging module 12 can be switched to the charging terminal 14 requesting charging in time, the power sharing of the charging and battery swapping station is better, the time-sharing multiplexing of the charging module 12 between the vehicle charging pile 141 and the battery charging bin 142 is realized, and the idle rate of the charging module is reduced. In addition, the number of the charging modules 12 is less than the number of the charging terminals 14, which can reduce and avoid the redundant setting of the equipment of the charging and battery swapping station, effectively reduce the size of the charging and battery swapping station, facilitate the landing of the charging and battery swapping station, and improve the economy of the charging and battery swapping station.

[0209] Of course, those skilled in the art can understand that the charging module 12 can also be in other forms according to the needs of specific application scenarios, such as a DC / AC module group, a DC / DC module group, an AC / AC module group, etc. In addition to the vehicle charging pile 141 and the battery charging bin 142, the charging terminal 14 can also include only one of the two.

[0210] Continuing to refer to FIG. 1In some embodiments of the above charging and battery swapping station, the charging and battery swapping station further comprises a power control unit 11, an auxiliary device 18, a battery swapping control panel 17, and a battery charging control panel 15. The power control unit 11 is in communication connection with the master control system 10, the power distribution unit 13, the charging module 12, and the charging terminal 14. The power control unit 11 is configured to receive the power distribution instructions of the master control system 10, issue control instructions to the power distribution unit 13 and the charging module 12 according to the power distribution instructions, collect and report the state information of the charging terminal 14, the state information of the power distribution unit 13, and the state information of the charging module 12 to the master control system 10. The power control unit 11 is in communication connection with the battery charging control panel 15 to obtain the state information of the batteries in the battery charging compartment 142, and is in communication connection with the charging pile 141 through the charging pile control panel built in the charging pile to obtain the state information of the charging pile 141. The power control unit 11 can be directly in communication connection with the above battery charging control panel 15 and charging pile control panel, or can be indirectly in communication connection through the master control system 10.

[0211] The battery swapping control panel 17 is in communication connection with the master control system 10, and controls the battery swapping process based on the battery swapping instructions of the master control system 10. The specific control process is a routine means in the art, and will not be described herein.

[0212] The battery charging control panel 15 is in communication connection with the master control system 10, the power control unit 11, and the battery management system (BMS), and is configured to be capable of performing battery charging management and battery state detection, reporting real-time state information to the power control unit 11, reporting real-time state information to the master control system 10, performing battery charging management based on the instructions of the master control system 10, and the like.

[0213] The charging pile 141 is in communication connection with the master control system 10 and the power control unit 11 through the charging pile control panel. The charging pile control panel is configured to communicate with and interact with the vehicle, obtain real-time information of the charging vehicle, perform vehicle charging management and real-time protection of charging based on the instructions of the master control system 10, report real-time state information to the power control unit 11, and report vehicle information to the master control system 10.

[0214] The auxiliary device 18 is in communication connection with the master control system 10. Specifically, the auxiliary device 18 comprises a battery swapping intelligent auxiliary system, a battery swapping interaction system, a liquid cooling system, a fire alarm system, and the like. The auxiliary device 18 is configured to provide functional services for charging and battery swapping based on the instructions of the master control system 10. The specific service mode is a routine means in the art, and will not be described herein.

[0215] In this way, upon receiving a charging request from the charging pile 141 or the battery charging compartment 142, the main control system 10 makes a charging decision based on the information received from each component, and then issues a power allocation command according to the decision result. The power control unit 11 can specifically control the power allocation of the charging and battery swapping station according to the power allocation command of the main control system 10, so as to better achieve power sharing of the charging and battery swapping station, realize time-sharing multiplexing of the charging module 12 among different charging terminals 14, and reduce the idle rate of the charging module. Other control units can perform corresponding process control based on the instructions of the main control system 10, and report relevant information to the main control system 10 in real time so that the main control system 10 can coordinate and control the system.

[0216] In some embodiments, the power distribution unit 13 of this application includes a plurality of first input terminals 131, a plurality of first output terminals 132, and a switch disposed between the first input terminals 131 and the first output terminals 132. The number of first output terminals 132 is greater than the number of first input terminals 131. Each first input terminal 131 is connected to a charging module 12, and each first output terminal 132 is connected to a charging terminal. By controlling the closing and opening of the switch between the first input terminals 131 and the first output terminals 132, the charging module 12 can distribute power to different charging terminals 14.

[0217] like FIG. 2 As shown, in one specific embodiment, the power distribution unit 13 has ten first input terminals 131 and fourteen first output terminals 132. The ten first input terminals 131 are connected one-to-one with the second output terminals 121 of ten charging modules 12 (each charging module 12 includes multiple AC / DC module groups). The ten first output terminals 132 are connected one-to-one with ten battery charging compartments 142. The other four first output terminals 132 are connected one-to-one with four charging piles 141. Further, each first input terminal 131 is connected to one of the ten first output terminals 132 corresponding to the battery charging compartment 142 via a first cable 137. Each first cable 137 is provided with a first switch 133, and every two first cables 137 form a group. The two first cables 137 in a group are connected by a second switch 134. Each first input terminal 131 is also connected to two first output terminals 132 corresponding to two charging piles 142 simultaneously via a second cable 138, and a third switch 135 and a fourth switch 136 are respectively provided between the two first output terminals 132 connected to the same second cable 138 and the second cable 138.

[0218] Thus, the charging module 12 can supply power to different charging terminals 14 by controlling the opening and closing of the first switch 133, the second switch 134, the third switch 135, and the fourth switch 136. Of course, it is necessary to avoid direct short circuits between different lines during the opening and closing process. In this application, the first switch 133, the second switch 134, the third switch 135, and the fourth switch 136 are preferably relays. However, those skilled in the art can use other switches such as circuit breakers or contactors as replacements.

[0219] It should be noted that the above embodiments are merely for illustrating the principles of this application and are not intended to limit the scope of protection of this application. Without departing from the principles of this application, those skilled in the art can adjust the above settings so that this application can be applied to more specific application scenarios.

[0220] For example, those skilled in the art will understand that the number of power distribution units 13 in this application can also be set to other numbers according to the needs of specific application scenarios. Furthermore, the number of vehicle charging piles 141 and battery charging compartments 142 can also be set to other numbers, as long as the number of charging terminals 14 is greater than the number of charging modules 12. In this case, the number of the first input terminals 131 and the first output terminals 132 of the power distribution units 13 also needs to be adjusted accordingly based on the number of charging modules 12 and charging terminals 14.

[0221] Exemplary method

[0222] The following reference FIG. 3 and FIG. 4 The charging management method of this application is described.

[0223] like FIG. 3 As shown, corresponding to the aforementioned charging and battery swapping station, this application provides a charging management method. The charging and battery swapping station includes X charging terminals and Y charging modules, where X > Y, and at least some of the charging modules are connected to multiple charging terminals. The charging management method includes the following steps:

[0224] S101, upon receiving a charging request from a charging terminal, confirm whether an available charging module exists. For example, upon receiving a charging request from a charging terminal such as a charging pile, confirm whether an available charging module exists based on the current usage of the charging module and the charging status of the charging terminal.

[0225] S102, when an available charging module is available, the available charging module is switched to the charging terminal requesting charging. Available charging modules include idle charging modules and switchable charging modules. For example, if an idle or switchable charging module is available, it can be directly switched to the charging terminal requesting charging. Alternatively, if a switchable charging module is available, it is switched out of the current charging terminal and switched to the charging terminal requesting charging.

[0226] This allows for timely switching of available charging modules to requesting charging terminals when they are available, effectively sharing power within the charging and battery swapping station and enabling time-sharing reuse of charging modules among charging terminals, thus reducing idle rates. Furthermore, since charging modules account for a significant portion of the overall charging system cost (over 50%) and double the system's volume, making site layout difficult, this configuration also reduces and avoids redundant equipment in the charging and battery swapping station, improving its economic efficiency and allowing for smaller footprints and wider deployment in various application scenarios.

[0227] The preferred embodiments of this application are described below.

[0228] In some embodiments of the above charging management method, confirming the availability of a charging module includes the following steps: Based on the charging terminal-charging module usage table, confirm whether Y charging terminals are already in operation. If Y charging terminals are already in operation, confirm that no charging module is available and send a charging request rejection message to the requesting charging terminal. If no Y charging terminals are in operation, confirm the existence of idle charging modules and / or switchable charging modules, and further confirm whether the idle charging modules and / or switchable charging modules are available.

[0229] For example, the charging terminal-charging module usage table can be stored in the main control system. The main control system updates the charging terminal-charging module usage table based on the information uploaded by the charging terminals and the power allocation unit, and calls the usage table to make business decisions when a new charging request is received. When Y charging terminals are already working, according to the charging strategy of this application, all Y charging modules are in working state. At this time, it is assumed that there are no available charging modules, and a charging request rejection message is sent to the requesting charging terminal. When no Y charging terminals are in working state, there must be idle charging modules, and / or multiple charging modules charging a charging terminal simultaneously. At this time, it is confirmed that there are available charging modules, but it is necessary to further determine whether the idle charging module and / or the switchable charging module can be used to charge the requesting charging terminal based on the type of available charging modules.

[0230] In this way, it is possible to determine whether there are any idle or switchable charging modules based on the usage of the charging terminal, and if there are any idle or switchable charging modules, it is possible to purposefully determine whether the charging module is available.

[0231] Of course, those skilled in the art will understand that, depending on the specific application scenario, even when Y charging terminals are already operational, there may be available charging modules. For example, based on charging priority, the requesting charging terminal can be compared with the lowest-priority charging terminal among the Y charging terminals currently charging. If the former has a higher priority than the latter, the charging module connected to the lowest-priority charging terminal can be switched to the requesting charging terminal. Alternatively, in another implementation, it may not be necessary to determine whether Y charging terminals are already operational; instead, it may directly determine whether an available charging module exists. Furthermore, instead of setting a charging terminal-charging module usage table, the usage status of the charging terminal and charging module can be obtained each time a charging request is received. However, this approach may lead to a decrease in control efficiency.

[0232] In some embodiments of the above charging management method, confirming whether an idle charging module is available includes the following steps: determining whether the idle charging module can connect to the charging terminal requesting charging. If yes, the idle charging module is confirmed to be available. If not, the idle charging module is confirmed to be unavailable.

[0233] For example, when an idle charging module exists, its availability can be determined by checking whether its first input terminal is connected to the first output terminal of the requesting charging terminal. If they are connected, the idle charging module is considered available, and it is then switched to the requesting charging terminal. This involves closing the relevant switches between the charging modules connected to the requesting terminal to charge it. Otherwise, if they are not connected, the idle charging module is considered unavailable. Of course, determining the availability of an idle charging module may also include other necessary checks, such as whether the charging module is faulty, or whether related switches or wiring are faulty.

[0234] In some embodiments of the above charging management method, confirming the availability of a switchable charging module includes the following steps: Starting with the charging terminal with the lowest priority according to a preset priority, determine whether a switchable charging module exists. If a switchable charging module exists, determine whether it can connect to the requesting charging terminal. If yes, the switchable charging module is confirmed to be available. If not, the switchable charging module is confirmed to be unavailable.

[0235] For example, the preset priority is not limited in this application, and those skilled in the art can choose it based on specific scenarios. For instance, the preset priority can be defined according to charging time order (e.g., the earlier the charging begins, the higher the priority), according to the urgency of charging (higher urgency, higher priority), according to required power / capacity (e.g., lower required power / capacity, higher priority), or according to the type of charging terminal (e.g., charging piles have higher priority than charging batteries). When a switchable charging module exists, starting with the charging terminal with the lowest priority, it is determined whether a switchable charging module exists, that is, whether two or more charging modules are connected to that charging terminal. If so, a switchable charging module exists, and the determination of its availability continues; otherwise, no switchable charging module exists, and the determination of the next charging terminal continues according to priority. When determining whether a switchable charging module is available, it is determined whether the first input terminal corresponding to the switchable charging module is connected to the first output terminal corresponding to the requesting charging terminal. When the two are connected, the switchable charging module is determined to be usable. At this time, the charging module is switched to the charging terminal requesting charging; that is, the relevant switch between the switchable charging module and the charging terminal is opened, and then the relevant switch between the switchable charging module and the charging terminal requesting charging is closed. Otherwise, when the two are not connected, the switchable charging module is determined to be unusable. Similarly, determining whether the switchable charging module is usable may also include other necessary judgment processes, such as whether the charging module is faulty, or whether the relevant switches or circuits are faulty.

[0236] In some embodiments of the above-described charging management method, the charging management method further includes:

[0237] When neither the idle charging module nor the switchable charging module is available, a message rejecting the charging request is sent to the charging terminal that requests charging.

[0238] For example, if there are available charging modules and / or switchable charging modules, and if both are deemed unavailable, a message rejecting the charging request is sent to the charging terminal requesting charging, such as through sound, light, or text.

[0239] Furthermore, based on the usage of charging modules, the availability status of charging terminals, such as charging piles, can be displayed in real time on the operation interface (such as the terminal APP interface). If there are no idle charging modules in the system or no charging modules that can be switched out, the charging terminal should be displayed as unavailable on the operation interface to avoid users making wasted trips.

[0240] In some embodiments of the above-mentioned charging management method, the charging management method further includes the following step: adding newly started charging terminals to the charging terminal queue according to a preset priority.

[0241] Taking the priority definition based on charging time as an example, after switching the charging module to the charging terminal that requests charging, the newly started charging terminal is added to the end of the charging terminal queue.

[0242] Of course, when the preset priorities are different, the newly started charging terminal can be added to other positions in the charging terminal queue according to the preset priority. For example, the charging terminal with the highest urgency of newly started charging can be added to the head of the charging terminal queue according to the importance and urgency of charging.

[0243] In some embodiments of the above-described charging management method, the charging management method further includes: when no charging request is received from a charging terminal, confirming whether there is an idle charging module; when an idle charging module exists, confirming whether there is an accessible charging terminal; and when an accessible charging terminal is confirmed, switching the idle charging module to the accessible charging terminal.

[0244] For example, during the charging process, some charging terminals may complete charging or switch to an idle state due to reduced power demand. To further reduce the idle rate of charging modules and improve reuse efficiency, when no charging request is received, it is necessary to determine whether there are idle charging modules, for example, by checking the charging terminal-charging module usage table. If an idle charging module exists, it is further confirmed whether it can be used to accelerate the charging efficiency of a particular charging terminal. If so, i.e., there is a usable charging terminal, the idle charging module is switched to the usable charging terminal to accelerate its charging efficiency.

[0245] This allows for the timely switching of idle charging modules to available charging terminals when such modules are available, further improving the utilization rate of the charging modules. Of course, in other implementations, the above steps can be selectively omitted, and the availability of a module can be determined only when a charging request is received.

[0246] In some embodiments of the above charging management method, confirming the existence of an accessible charging terminal includes: according to a preset priority, starting with the highest priority charging terminal, determining whether an idle charging module can connect to a charging terminal that is in operation. If yes, then it is determined that an accessible charging terminal exists. If not, then it is determined that no accessible charging terminal exists.

[0247] For example, the preset priorities have been described in the above embodiments and will not be repeated here. Taking the priority definition based on charging time sequence as an example, when there are idle modules, starting with the charging terminal that started charging first, it is determined whether an idle charging module is connected to that charging terminal; if so, the charging terminal with the highest priority is determined as the accessible charging terminal. Otherwise, the next charging terminal is determined to be connected to an idle charging module according to priority, until all charging terminals have been determined. If none of the charging terminals can be connected to an idle charging module, then it is determined that there are no accessible charging terminals. The determination methods for other priorities are similar and will not be repeated here.

[0248] In this way, when there are idle modules, the charging efficiency of high-priority charging terminals can be improved according to their priority.

[0249] In some embodiments of the above-mentioned charging management method, the charging management method further includes: updating the charging terminal-charging module usage table.

[0250] For example, the above-mentioned updated charging terminal-charging module usage table can be updated in real time, at regular intervals, or after each charging module switchover.

[0251] In this way, the charging terminal-charging module usage table can be updated in a timely manner based on specific usage conditions, providing timely and effective information for power sharing, so as to further improve the efficiency and effectiveness of power sharing.

[0252] Below, in conjunction with FIG. 4 One possible operation process of the charging management method of this application is described.

[0253] like FIG. 4 As shown, in the operation of a possible charging management method, S301 is executed first to determine whether a charging request from the charging terminal has been received. If so, S302 is executed; otherwise, S312 is executed.

[0254] S302, determine whether Y charging terminals are already in working state. If yes, execute S309; ​​otherwise, execute S303.

[0255] S303: Determine if there is an idle charging module. If yes, execute S310; otherwise, execute S304.

[0256] S304. According to the preset priority, determine whether there is a switchable charging module. If so, execute S305; otherwise, execute S309.

[0257] S305, determine whether the switchable charging module is available. If yes, proceed to S306; otherwise, proceed to S309.

[0258] S306, switch the switchable charging module to the charging terminal that requests charging.

[0259] S307, add the newly started charging terminal to the end of the charging priority queue.

[0260] S308, Update the charging module - charging terminal usage table.

[0261] S309, Reject the charging terminal's charging request.

[0262] S310: Determine if an idle charging module is available. If yes, execute S311; otherwise, return to execute S304.

[0263] S311, switch the idle charging module to the charging terminal that requests charging.

[0264] S312: If no charging request is received from the charging terminal, determine whether there is an idle charging module. If so, execute S313; otherwise, terminate the program directly.

[0265] S313, according to the preset priority, starts with the charging terminal with the highest priority and selects the charging terminal that can speed up charging.

[0266] S314, determine whether the charging terminal is selected. If yes, execute S315; otherwise, execute S316.

[0267] S315, switch the idle charging module to the accessible charging terminal, and return to execute S308.

[0268] S316: Determine if there are other idle charging modules. If so, execute S313; otherwise, end the program.

[0269] It should be noted that although the detailed steps of the method of this application have been described in detail above, those skilled in the art can combine, split and rearrange the above steps without departing from the basic principles of this application. Such modified technical solutions do not change the basic concept of this application and therefore fall within the protection scope of this application.

[0270] Exemplary system

[0271] Below, we will combine FIG. 5 An exemplary system of this application is described below. It should be understood that the description of the method embodiments corresponds to the description of the system embodiments; therefore, any parts not described in detail can be referred to the foregoing method embodiments.

[0272] like FIG. 5As shown, this application also provides a charging management system 400 for a charging and battery swapping station. The charging and battery swapping station includes X charging terminals and Y charging modules, where X > Y. At least some of the charging modules are connected to multiple charging terminals. The charging management system 400 includes a first confirmation module 401 and a switching module 402. The first confirmation module 401 is configured to confirm whether an available charging module exists when a charging request is received from a charging terminal. The switching module 402 is configured to switch an available charging module to the requesting charging terminal when an available charging module exists. The available charging modules include idle charging modules and switchable charging modules.

[0273] In this way, when the first confirmation module 401 confirms the existence of an available charging module, the switching module 402 can promptly switch the available charging module to the charging terminal requesting charging, thus achieving better power sharing at the charging and battery swapping station and resulting in a better power sharing effect. Furthermore, it can reduce and avoid redundant equipment settings at the charging and battery swapping station, improving the economic efficiency of the station.

[0274] In some embodiments of the charging management system 400, the first confirmation module 401 is configured to confirm whether there is an available charging module by: confirming whether Y charging terminals are already in working state according to the charging terminal-charging module usage table between charging terminals and charging modules; if no Y charging terminals are in working state, confirming the existence of idle charging modules and / or switchable charging modules; and confirming whether the idle charging modules and / or switchable charging modules are available.

[0275] In this way, the first confirmation module 401 can confirm whether there is an idle charging module or a switchable charging module based on the usage of the charging terminal. If there is an idle charging module or a switchable charging module, it can purposefully confirm whether there is an available charging module.

[0276] In some embodiments of the charging management system 400 described above, the first confirmation module 401 is further configured to confirm whether an idle charging module is available by: determining whether the idle charging module can be connected to a charging terminal requesting charging; if so, confirming that the idle charging module is available; if not, confirming that the idle charging module is unavailable.

[0277] In this way, the first confirmation module 401 can confirm whether the idle charging module is available by confirming whether the idle charging module requests charging from the charging terminal connection.

[0278] In some embodiments of the charging management system 400 described above, the first confirmation module 401 is further configured to confirm whether the switchable charging module is available by means of:

[0279] According to the preset priority, starting from the charging terminal with the lowest priority, it is determined whether there is a switchable charging module;

[0280] When a switchable charging module exists, determine whether the switchable charging module can connect to the charging terminal that requests charging.

[0281] If so, confirm that the cut-out charging module is available;

[0282] If not, then confirm that the detachable charging module is unavailable.

[0283] In this way, the first confirmation module 401 can confirm whether a switchable charging module exists based on the priority of the charging terminal. Then, if a switchable charging module exists, it confirms whether the charging module is usable based on whether the charging module can be connected to the charging terminal requesting charging.

[0284] In some embodiments of the charging management system 400 described above, the charging management system 400 further includes:

[0285] The information sending module 406 is configured to send a charging rejection message to the charging terminal requesting charging when both the idle charging module and the switchable charging module are unavailable.

[0286] In this way, when neither the idle charging module nor the switchable charging module is available, the information sending module 406 can purposefully send a message to the charging terminal requesting charging a refusal request.

[0287] In a specific implementation of the charging management system 400, the first confirmation module 401 is further configured to confirm that there is no available charging module when Y charging terminals are already in operation; the information sending module 406 is further configured to send a message to the charging terminal requesting charging to refuse charging.

[0288] When the above technical solution is adopted, the first confirmation module 401 can confirm that there is no available charging module when Y charging terminals are already working. At this time, the information sending module 406 sends a message to the charging terminal requesting charging to refuse the charging request.

[0289] In some embodiments of the charging management system 400 described above, the charging management system 400 further includes a queue update module 405, which is configured to add newly started charging terminals to the charging terminal queue according to a preset priority.

[0290] In this way, the queue update module 405 can replenish the charging terminal queue information in a timely manner according to the usage of the charging terminals.

[0291] In some embodiments of the charging management system 400 described above, the charging management system 400 further includes:

[0292] The second confirmation module 403 is configured to confirm whether there is an idle charging module when no charging request is received from the charging terminal.

[0293] The third confirmation module 404 is configured to confirm whether there is an accessible charging terminal when there is an idle charging module.

[0294] The switching module 402 is further configured to switch the idle charging module to the accessible charging terminal when it is confirmed that an accessible charging terminal exists.

[0295] In this way, when there are idle charging modules, the switching module 402 can promptly switch the idle charging module to an accessible charging terminal, further improving the effect of power sharing.

[0296] In some embodiments of the charging management system 400 described above, the third confirmation module 404 is further configured to confirm the existence of an accessible charging terminal by means of:

[0297] According to the preset priority, starting from the highest priority charging terminal, it is determined whether an idle charging module can connect to a charging terminal that is in operation.
