Description

Technical Field

[0001] The embodiments of the present application relate to the technical field of charging equipment, and in particular to a method for recommending a charging gun. Background Art

[0002] In related technologies, charging stack power topologies primarily include ring and matrix topologies. Compared to the matrix topology, the ring topology offers advantages such as a smaller number of switches, higher stability and reliability, and easier maintenance. Therefore, the ring topology and its optimized configurations have become the mainstream choice for charging stack power architectures.

[0003] However, the ring topology charging stack has power island and power scheduling limitation problems, and its overall energy efficiency and resource utilization are insufficient, resulting in a low station turnover rate. Summary of the Invention

[0004] An embodiment of the present application provides a method for recommending charging guns, which can determine the optimal recommended charging gun from a first set of charging guns that meets the current charging scenario (reserving an adjacent charging module for power parallel connection for the second charging gun) and takes into account the health of the charging guns, thereby improving resource utilization and system energy efficiency, thereby increasing the turnover rate of the station and extending the service life of the charging gun.

[0005] To achieve the above objectives, the present invention adopts the following technical solutions:

[0006] In the first aspect, an embodiment of the present application provides a method for recommending a charging gun, which is applied to a main controller of a charging stack. The charging stack includes multiple charging modules connected in a ring topology, each charging module is configured with a corresponding charging gun, and supports power parallel connection with adjacent charging modules. The method includes: determining a first set of charging guns in an idle state and a second set of charging guns in a charging state from multiple charging guns; determining one or more health parameters corresponding to each first charging gun in the first charging gun set, and charging parameters of each second charging gun in the second charging gun set; determining a recommendation coefficient of each first charging gun based on the one or more health parameters corresponding to each first charging gun and the charging parameters of each second charging gun; determining a recommended charging gun from the first charging gun set based on the recommendation coefficient of each first charging gun, the number of second charging guns in the second charging gun set, and the ring topology.

[0007] Based on this solution, since one or more health parameters corresponding to an idle first charging gun can, to a certain extent, reflect the health of the first charging gun and its corresponding charging module, and since the second charging parameter of a charging second charging gun can, to a certain extent, reflect the likelihood of its adjacent first charging gun being quickly deployed, a recommendation coefficient reflecting the health and quick deployment likelihood of each first charging gun can be determined based on the one or more health parameters of each first charging gun and the charging parameter of each second charging gun. Furthermore, when the number of second charging guns in the second charging gun set and the ring topology accurately reflect the positional relationship between each first and second charging gun and the actual charging scenario, the optimal recommended charging gun that meets the current charging scenario (maximum reserving adjacent charging modules for power parallel connection for the current second charging gun) and takes into account the health of the charging guns can be determined from the first charging gun set based on the recommendation coefficients of each first charging gun, the number of second charging guns in the second charging gun set, and the ring topology. This improves resource utilization and system energy efficiency, thereby increasing the station turnover rate and extending the service life of the charging guns.

[0008] In some embodiments of the present application, a recommendation coefficient for each first charging gun is determined based on one or more health parameters corresponding to each first charging gun and the charging parameters of each second charging gun, including: determining the relative charging parameters of each first charging gun based on the charging parameters of each second charging gun; determining the recommendation coefficient of each first charging gun based on the weighted coefficients corresponding to each health parameter and the relative charging parameter, as well as each health parameter and the relative charging parameter of the first charging gun.

[0009] Based on this solution, when the weighted coefficients corresponding to each health parameter and relative charging parameter can accurately reflect the degree of influence of the possibility of the first charging gun being called, based on the weighted coefficients corresponding to each health parameter and relative charging parameter and the health parameters and relative charging parameters of the first charging gun, the recommended coefficient that takes into account both the health status of the first charging gun and the current charging scenario can be determined.

[0010] In some embodiments of the present application, the charging parameter is the time required for full charging; based on the charging parameters of each second charging gun, the relative charging parameters of each first charging gun are determined, including: determining two adjacent charging guns of each first charging gun; and taking the minimum value of the time required for full charging of the two adjacent charging guns as the relative charging parameter of the first charging gun.

[0011] Based on this solution, since the relative charging parameter of the first charging gun is the minimum time required for full charging of two adjacent charging guns, it can cover the maximum possibility of quickly calling the first charging gun and the second charging gun that is about to complete the charging task.

[0012] In some embodiments of the present application, a recommended charging gun is determined from the first charging gun set based on the recommendation coefficient of each first charging gun, the number of second charging guns in the second charging gun set, and the ring topology structure, including: when the number of second charging guns is zero, the first charging gun corresponding to the lowest recommendation coefficient is used as the recommended charging gun; when the number of second charging guns is greater than zero, the recommended charging gun is determined from the first charging gun set based on the number of second charging guns and the ring topology structure.

[0013] This solution determines the recommended charging gun based on the recommendation coefficients of each charging gun when the number of second charging guns is zero, and selects the first charging gun with the lowest recommendation coefficient as the recommended charging gun. This method integrates the health of the first charging gun and the current charging scenario, and the optimal recommendation solution is achieved when the recommendation coefficient is higher and the recommendation level is lower.

[0014] In some embodiments of the present application, a recommended charging gun is determined from the set of first charging guns based on the number of second charging guns and the ring topology, including: when the number of second charging guns is 1, the first charging gun with the second highest recommendation coefficient among the two adjacent first charging guns of the second charging gun is used as the recommended charging gun; when the number of second charging guns is greater than 1, the recommended charging gun is determined from the set of first charging guns based on the ring topology.

[0015] This solution uses the recommendation coefficients of the two adjacent first charging guns as the recommended charging gun when the number of second charging guns is one. This method reserves charging modules for power parallel connection with the second charging gun while also taking into account the health of the first charging guns. It is the optimal solution when the recommendation coefficient is higher and the recommendation level is lower.

[0016] In some embodiments of the present application, based on the ring topology, a recommended charging gun is determined from the first charging gun set, including: based on the ring topology, determining one or more first charging gun groups consisting of first charging guns separated by second charging guns; wherein the first charging gun group includes one or more sequentially adjacent first charging guns; based on the status of the charging modules corresponding to each first charging gun in the first charging gun group, determining a dispatchable charging gun from the first charging gun group; wherein the dispatchable charging gun is a first charging gun corresponding to the charging module in an idle state; based on the number of dispatchable charging guns in each first charging gun group, determining a recommended charging gun from one or more first charging gun groups.

[0017] Based on this solution, since the first charging gun group is composed of one or more sequentially adjacent first charging guns separated by second charging guns, it can accurately reflect the usage of the charging guns in the charging stack. Furthermore, due to the status of the charging module corresponding to each first charging gun, it can reflect whether the charging module corresponding to the first charging gun is supplying power in parallel to the charging module corresponding to the adjacent second charging gun, thereby excluding first charging guns that are unavailable due to power sharing and accurately determining the dispatchable charging guns. Therefore, the number of dispatchable charging guns in each first charging gun group can accurately reflect the actual charging scenario. Based on the number of dispatchable charging guns in each first charging gun group, it is possible to determine the recommended charging gun that meets the actual scenario from one or more first charging gun groups.

[0018] In some embodiments of the present application, based on the number of dispatchable charging guns in each first charging gun group, a recommended charging gun is determined from one or more first charging gun groups, including: when the number of dispatchable charging guns in one or more first charging gun groups is not zero, based on the number of dispatchable charging guns in each first charging gun group and the recommendation coefficient of each dispatchable charging gun, the recommended charging gun is determined from one or more dispatchable charging guns; when the number of dispatchable charging guns in one or more first charging gun groups is zero, based on the recommendation coefficient of each first charging gun, the recommended charging gun is determined from one or more first charging gun groups.

[0019] Based on this solution, if one or more first charging gun groups have dispatchable charging guns, a recommended charging gun is determined from the one or more dispatchable charging guns based on the number of dispatchable charging guns in each first charging gun group and the recommendation coefficient of each dispatchable charging gun. If one or more first charging gun groups do not have dispatchable charging guns, a recommended charging gun is determined from the one or more first charging gun groups based on the recommendation coefficient of each first charging gun. In this way, regardless of whether there are dispatchable charging guns, a recommended charging gun that meets the actual scenario and takes into account health conditions can be determined to a certain extent.

[0020] In some embodiments of the present application, based on the number of dispatchable charging guns in each first charging gun group and the recommendation coefficient of each dispatchable charging gun, a recommended charging gun is determined from one or more dispatchable charging guns, including: determining a target charging gun group based on the number of dispatchable charging guns in each first charging gun group; wherein the target charging gun group is the first charging gun group corresponding to the largest number of dispatchable charging guns; determining a recommended charging gun from the target charging gun group based on the number of dispatchable charging guns in the target charging gun group, or based on the number of dispatchable charging guns in the target charging gun group and the recommendation coefficient of each dispatchable charging gun.

[0021] Based on this solution, since the target charging gun group is the first charging group corresponding to the maximum number of schedulable charging guns, selecting the recommended charging gun from the target charging gun group can reserve the charging module for power parallel connection for the recommended charging gun to the greatest extent. Therefore, based on the number of schedulable charging guns in the target charging gun group, or based on the number of schedulable charging guns in the target charging gun group and the recommended coefficient of each schedulable charging gun, it is possible to meet the user's charging power requirements as much as possible while determining the recommended charging gun from the target charging gun group that meets the actual scenario and takes into account the health condition.

[0022] In some embodiments of the present application, the target charging gun group corresponds to a first charging gun group; based on the number of dispatchable charging guns in the target charging gun group, or based on the number of dispatchable charging guns in the target charging gun group and the recommendation coefficient of each dispatchable charging gun, the recommended charging gun is determined from the target charging gun group, including: when the number of dispatchable charging guns in the target charging gun group is an odd number and greater than 1, a dispatchable charging gun in the middle position of the target charging gun group is used as the recommended charging gun; when the number of dispatchable charging guns in the target charging gun group is an even number and greater than 2, from the two dispatchable charging guns in the middle position of the target charging gun group, the dispatchable charging gun with a lower recommendation coefficient is selected as the recommended charging gun.

[0023] Based on this solution, since the target charging gun group is the first charging gun group corresponding to the maximum number of schedulable charging guns, selecting the recommended charging gun from the target charging gun group can maximize the amount of charging modules reserved for the recommended charging guns for parallel connection, thus avoiding the occurrence of power islands. Furthermore, if the number of schedulable charging guns in the target charging gun group is an odd number and greater than 1, the schedulable charging gun in the middle of the target charging gun group is selected as the recommended charging gun. If the number of schedulable charging guns in the target charging gun group is an even number and greater than or equal to 2, the schedulable charging gun with the lower recommendation coefficient is selected from the two schedulable charging guns in the middle of the target charging gun group as the recommended charging gun. In the case where a larger recommendation coefficient indicates a lower recommendation degree, this solution is the optimal charging gun recommendation solution, which can maximize the amount of charging modules reserved for the recommended charging guns for parallel connection, improving resource utilization, system energy efficiency, and extending the service life of the charging guns.

[0024] In some embodiments of the present application, a target charging gun group corresponds to multiple first charging gun groups; based on the number of schedulable charging guns in the target charging gun group, or based on the number of schedulable charging guns in the target charging gun group and the recommendation coefficient of each schedulable charging gun, a recommended charging gun is determined from the target charging gun group, including: when the number of schedulable charging guns in each first charging gun group corresponding to the target charging gun group is an odd number and greater than 1, extracting a schedulable charging gun in the middle position of each first charging gun group to obtain a first candidate charging gun set, and taking the candidate charging gun with the lowest recommendation coefficient in the first candidate charging gun set as the recommended charging gun; when the number of schedulable charging guns in each first charging gun group corresponding to the target charging gun group is an even number and greater than 2, extracting two schedulable charging guns in the middle position of each first charging gun group to obtain a second candidate charging gun set; and taking the candidate charging gun with the lowest recommendation coefficient in the second candidate charging gun set as the recommended charging gun.

[0025] Based on this solution, since the target charging gun group is the first charging gun group corresponding to the maximum number of dispatchable charging guns, selecting recommended charging guns from the target charging gun group maximizes the amount of power reserved for parallel charging modules for the recommended charging guns, thus avoiding the occurrence of power islands. Furthermore, if the number of dispatchable charging guns in each first charging gun group corresponding to the target charging gun group is an odd number and greater than 1, the dispatchable charging gun with the lowest recommendation coefficient in the middle position of each first charging gun group is selected as the recommended charging gun. If the number of dispatchable charging guns in each first charging gun group corresponding to the target charging gun group is an even number and greater than 2, the dispatchable charging gun with the lowest recommendation coefficient in the middle position of each first charging gun group is selected as the recommended charging gun. This solution is the optimal charging gun recommendation solution, as a larger recommendation coefficient indicates a lower recommendation level. It maximizes the amount of power reserved for the recommended charging guns, improving resource utilization, system energy efficiency, and extending the service life of the charging guns.

[0045] The following will describe the technical solutions in the embodiments of the present application in conjunction with the accompanying drawings. To facilitate the clear description of the technical solutions in the embodiments of the present application, the first, second, etc. descriptions in the embodiments of the present application are only used for illustration and to distinguish the described objects. There is no order, nor does it represent a special limitation on the number of devices in the embodiments of the present application, and it does not constitute any limitation on the embodiments of the present application.

[0046] The following is an explanation of the relevant technical terms in the embodiments of this application:

[0047] A charging stack is a centralized electric vehicle charging system that integrates multiple charging modules, power distribution units (PDUs), intelligent power distribution units, and a master controller to achieve efficient and dynamic power distribution for multiple electric vehicles. Its core goal is to maximize charging power utilization within limited grid capacity and support simultaneous fast charging for multiple vehicles.

[0048] The charging module is the unit in the charging stack that independently performs alternating current / direct current (AC / DC) or DC / DC power conversion. It usually includes a power circuit, a control unit, and a heat dissipation unit.

[0049] The charging gun is an intelligent, highly integrated power interface used to connect the charging stack with the key terminal equipment of the electric vehicle, and is responsible for power transmission, signal interaction and safety.

[0050] The main controller is the system's core decision-making unit, responsible for global power scheduling, charging strategy optimization, device health management, and safety control. Through real-time data processing and intelligent algorithms, it coordinates components such as the charging module, PDU, and charging gun to achieve efficient and safe charging services. The main controller typically adopts a multi-processor heterogeneous architecture and can combine at least two of the following: a digital signal processor (DSP), a microcontroller unit (MCU), a field-programmable gate array (FPGA), and a multi-core system on chip (SOC).

[0051] Charging stations, also known as stations, provide centralized power infrastructure for electric vehicles, encompassing charging equipment, distribution systems, operations management platforms, and supporting services. Their core goal is to deliver efficient, safe, and intelligent charging services at scale.

[0052] The turnover rate is a core indicator for measuring the operational efficiency of charging stations. It reflects the number of vehicles served by a single charging station within a unit of time and directly affects station revenue and user experience. The turnover rate is the quotient of the total number of vehicles that have completed charging within a unit of time and the number of available charging stations.

[0053] An embodiment of the present application provides a method for recommending charging guns, which is applied to a main controller of a charging stack. The charging stack includes multiple charging modules connected in a ring topology, each of which is configured with a corresponding charging gun and supports power parallel connection with adjacent charging modules. The method determines, from a plurality of charging guns, a first set of charging guns in an idle state and a second set of charging guns in a charging state; determines one or more health parameters corresponding to each first charging gun in the first set of charging guns, and charging parameters of each second charging gun in the second set of charging guns; determines a recommendation coefficient for each first charging gun based on the one or more health parameters corresponding to each first charging gun and the charging parameters of each second charging gun; and determines a recommended charging gun from the first set of charging guns based on the recommendation coefficient of each first charging gun, the number of second charging guns in the second set of charging guns, and the ring topology. Because one or more health parameters corresponding to an idle first charging gun can, to a certain extent, reflect the health of the first charging gun and its corresponding charging module, and because a second charging parameter of a charging second charging gun can, to a certain extent, reflect the likelihood of its adjacent first charging gun being quickly deployed, a recommendation coefficient reflecting the health and quick deployment likelihood of each first charging gun can be determined based on the one or more health parameters of each first charging gun and the charging parameters of each second charging gun. Furthermore, when the number of second charging guns in the second charging gun set and the ring topology accurately reflect the positional relationship between each first and second charging gun and the actual charging scenario, an optimal recommended charging gun that meets the current charging scenario (maximum reserving adjacent charging modules for power parallel connection for the current second charging gun) and takes into account charging gun health can be determined from the first charging gun set based on the recommendation coefficients of each first charging gun, the number of second charging guns in the second charging gun set, and the ring topology. This improves resource utilization and system energy efficiency, thereby increasing the station turnover rate and extending the service life of the charging guns.

[0054] The recommended method for the charging gun provided in the embodiment of the present application can be applied to Figure 1 In the main controller shown. Figure 1 This is a schematic diagram of the structure of a charging stack provided in an embodiment of the present application. Figure 1As shown, taking the charging stack 10 including 6 charging modules as an example, the charging stack 10 may include a PDU 101, first charging modules 102 to 107, charging guns A to F, and a main controller 108. The PDU 101, first charging modules 102 to 107, and main controller 108 are all located in a cabinet, while charging guns A to F are all located outside the cabinet. The PDU 101 is connected to the first charging modules 102 to 107 (connected by solid lines) and is used to distribute electrical energy to each charging module. The first charging modules 102 to 107 are correspondingly connected to charging guns A to F (connected by solid lines), and charging guns A to F are used to connect to the target charging object (e.g., an electric vehicle). The first charging modules 102 to 107 are used to convert electrical energy (e.g., input AC power) into the voltage / current required by the vehicle and transmit the electrical energy to the target charging object through the charging guns. The main controller 108 is connected to the PDU 101, the first charging module 102 to the sixth charging module 107, and the charging guns A to F. It is used to adjust power distribution through the PDU, control the output parameters of the charging module, and manage the start and stop of the charging gun.

[0055] Continue to refer Figure 1 As shown, since each charging module from the first to the sixth charging module 102 to 107 can be connected to an adjacent charging module to form a closed ring, the first to sixth charging modules 102 to 107 can be considered to be connected in a ring topology. Specifically, a switch S1 is configured between the first and second charging modules 102 to 103, a switch S2 is configured between the second and third charging modules 103 to 104, a switch S3 is configured between the third and fourth charging modules 104 to 105, a switch S4 is configured between the fourth and fifth charging modules 105 to 106, a switch S5 is configured between the fifth and sixth charging modules 106 to 107, and a switch S6 is configured between the sixth charging module 107 and the first charging module 102. The main controller 108 can achieve power parallel connection with adjacent charging modules by controlling the closing of switches S1 to S6. For example, when S1 is closed, the power of the first charging module 102 and the second charging module 103 can be combined to meet the high power output request of one charging gun.

[0056] Figure 2 This is a flow chart of a recommended method for a charging gun provided in an embodiment of the present application. The recommended method for the charging gun can be applied to Figure 1 The main controller 108 shown. And the recommended method of the charging gun can be executed after any one of the multiple charging guns in the charging stack changes from the charging state to the idle state, regardless of whether the target charging object enters the charging station for charging. Figure 2As shown, the recommended method for the charging gun may include the following steps 201 to 204.

[0057] Step 201: Determine a first set of charging guns in an idle state and a second set of charging guns in a charging state from a plurality of charging guns.

[0058] refer to Figure 1 As shown, the main controller 108 can obtain the status of each charging gun among the charging guns A to F of the charging stack 10, and determine the first charging gun set and the second charging gun set according to the status of each charging gun.

[0059] In some examples, the main controller 108 may monitor the output current and voltage of each charging gun among charging guns A to F, and determine whether the status of charging guns A to F is a charging state or an idle state based on the output current and voltage of each charging gun.

[0060] In other examples, charging guns A to F may proactively report status information indicating whether they are in a charging state or an idle state to the main controller 108. The present embodiment of the application does not limit the manner in which the main controller 108 obtains the status of each charging gun.

[0061] Continue to refer Figure 1 As shown in the figure, among charging guns A to F, if charging guns A to E are all in the idle state and charging gun F is in the charging state, then the first charging gun set includes charging guns A to E, and the second charging gun set includes charging gun F. If charging guns A, C, and F are in the idle state, and charging guns B, D, and E are in the charging state, then the first charging gun set includes charging guns A, C, and F, and the second charging gun set includes charging guns B, D, and E.

[0062] Step 202: Determine one or more health parameters corresponding to each first charging gun in the first charging gun set, and charging parameters corresponding to each second charging gun in the second charging gun set.

[0063] Health parameters may be parameters that affect the health of the charging gun. In some examples, one or more health parameters may include one or both of the number of charge cycles of the first charging gun and the total output power of the first charging gun. In other examples, one or more health parameters may include one or more of the number of charge cycles of the first charging gun, the total output power of the first charging gun, and the total output power of the charging module corresponding to the first charging gun. The embodiments of the present application do not limit the specific type of the one or more health parameters.

[0064] For example, the one or more health parameters include one or both of the number of charging times of the first charging gun and the total output power of the first charging gun. Figure 1As shown, the main controller 108 can directly count the number of charge times and total output power of each first charging gun, or can receive the number of charge times and total output power reported by each first charging gun. This embodiment of the application does not limit the specific implementation method of determining one or more health parameters of each first charging gun. This embodiment of the application uses the example of the main controller 108 directly counting the number of charge times and total output power of each first charging gun as an example for illustration.

[0065] For example, the one or more health parameters may include one or more of the number of charging times of the first charging gun, the total output power of the first charging gun, and the total output power of the charging module corresponding to the first charging gun. Figure 1 As shown, the main controller 108 can directly count the charging times and total output power of each first charging gun, as well as the total output power of the charging module corresponding to the first charging gun.

[0066] The charging parameters may include the time required for full charging. The time required for full charging refers to the time from the current moment of the charging gun to the full charging moment. And it can be determined based on the charging speed of the charging gun and the current charging percentage. In some examples, the full charging moment refers to the moment when the charging gun fully charges the target charging object (such as a charging vehicle). The embodiment of the present disclosure does not limit the basis for judging whether the charging gun has fully charged the target charging object. The target charging object is determined to be fully charged when the power of the target charging object is greater than a preset power percentage. For example, the preset power can be any power percentage greater than or equal to 90%.

[0067] In other examples, the full charge time refers to the time when the charging gun charges the target charging object and the target charging object's power reaches the required power level. For example, if the required power level is 60% of the total power, the full charge time refers to the time when the target charging object's power level reaches 60%.

[0068] The embodiments of the present disclosure do not limit the specific definition of the full charging moment. The embodiments of the present disclosure use the example of the full charging moment being the moment when the charging gun fully charges the target charging object for illustrative explanation.

[0069] For example, the full charge moment refers to the moment when the charging gun fully charges the target charging object. Figure 1 As shown, the main controller 108 can obtain the charging speed and current charging percentage of the second charging gun by communicating with the target charging object, and calculate the time required for full charging based on the charging speed and current charging percentage of the second charging gun.

[0070] For example, the time required for full charging can be calculated by referring to the following formula (1):

[0071] T=(100%-E%) / Vcharge*t (1)

[0072] Where T represents the time required for a full charge, E% represents the current charge percentage, Vcharge represents the charging speed of the second charging connector, and t represents the gear time. The gear time refers to the duration of a fixed power / speed gear during the charging process, that is, the time interval during which the charging system operates at a fixed charging speed (Vcharge).

[0073] In some examples, since the first charging gun in the idle state can directly charge the target charging object without any waiting time, the time required to fully charge the first charging gun in the idle state may be zero.

[0074] Step 203 : Determine a recommendation coefficient for each first charging gun based on one or more health parameters corresponding to each first charging gun and charging parameters of each second charging gun.

[0075] The recommendation coefficient can be a coefficient used to indicate the degree of recommendation. The larger the recommendation coefficient, the lower the degree of recommendation, and vice versa. Figure 1 As shown, the main controller 108 may perform weighted processing on one or more health parameters corresponding to each first charging gun and the charging parameters of each second charging gun to obtain a recommendation coefficient corresponding to the first charging gun.

[0076] Step 204 : Determine a recommended charging gun from the first charging gun set based on the recommendation coefficient of each first charging gun, the number of second charging guns in the second charging gun set, and the ring topology.

[0077] The number of second charging guns in the second charging gun set can be greater than or equal to 0 and less than the total number of charging guns in the charging stack. For example, if the total number of charging guns in the charging stack is 6, the number of second charging guns in the second charging gun set can be greater than or equal to 0 and less than 6.

[0078] like Figure 1 As shown, a ring topology can be formed by sequentially connecting the first charging module 102 to the sixth charging module 107. The main controller 108 can select a recommended charging gun from the first charging gun set based on preset rules, taking into account the recommendation coefficient of the first charging gun, the number of second charging guns in the second charging gun set, and the ring topology.

[0079] In some examples, the main controller 108 may first determine the current actual charging scenario based on preset rules and the number of second charging guns in the second charging gun set and the ring topology structure, and then determine the recommended charging gun from the first charging gun set in combination with the recommendation coefficient of each first charging gun.

[0080] Embodiments of the present application provide a method for recommending charging guns. Because one or more health parameters corresponding to an idle first charging gun can, to a certain extent, reflect the health of the first charging gun and its corresponding charging module, and a second charging parameter of a charging second charging gun can, to a certain extent, reflect the likelihood of its adjacent first charging gun being quickly deployed, a recommendation coefficient reflecting the health and quick deployment likelihood of each first charging gun can be determined based on the one or more health parameters of each first charging gun and the charging parameters of each second charging gun. Furthermore, when the number of second charging guns in a second charging gun set and the ring topology accurately reflect the positional relationship between each first and second charging gun and the actual charging scenario, the optimal recommended charging gun from the first charging gun set can be determined based on the recommendation coefficients of each first charging gun, the number of second charging guns in the second charging gun set, and the ring topology, which meets the current charging scenario (maximum reserving adjacent charging modules for power parallel connection for the current second charging gun) while also taking into account the health of the charging guns. This improves resource utilization, system energy efficiency, and extends the service life of the charging guns.

[0081] like Figure 3 As shown in the above Figure 2 Based on the illustrated embodiment, step 203 determines the recommended coefficient of each first charging gun based on one or more health parameters corresponding to each first charging gun and the charging parameters of each second charging gun, and may include the following steps 2031 to 2033.

[0082] Step 2031: Determine relative charging parameters of each first charging gun based on the charging parameters of each second charging gun.

[0083] For example, the relative charging parameter may be a parameter used to characterize the likelihood of the first charging gun being quickly called. In some examples, the relative charging parameter may be the minimum full charging time required for two charging guns adjacent to the first charging gun.

[0084] In some embodiments of the present application, the charging parameter is the time required for full charging. Determining the relative charging parameters of each first charging gun based on the charging parameters of each second charging gun may include: determining two adjacent charging guns of each first charging gun; and using the minimum value of the time required for full charging of the two adjacent charging guns as the relative charging parameter of the first charging gun.

[0085] For example, the two adjacent charging guns may both be first charging guns, or both be second charging guns, or one may be first charging gun and the other may be second charging gun. The embodiment of the present application does not limit the types of the two adjacent charging guns.

[0086] If at least one of the two adjacent charging guns is the first charging gun, the relative charging parameter of the first charging gun can be directly determined to be 0. If both adjacent charging guns are the second charging gun, the minimum of the full-charge times of the two adjacent charging guns can be used as the relative charging parameter of the first charging gun. Because the relative charging parameter of the first charging gun is the minimum of the full-charge times of the two adjacent charging guns, it can maximize the possibility of quickly calling the first charging gun and the second charging gun that is about to complete its charging task.

[0087] like Figure 1 As shown, taking the example of a first charging gun set including charging guns A and charging gun F, and a second charging gun set including charging guns B, charging gun C, charging gun D, ​​and charging gun E, the main controller 108 may first determine, when determining the relative charging parameter of charging gun A, that the two adjacent charging guns of charging gun A are charging guns B and charging gun F. Furthermore, when charging gun B is the second charging gun (the corresponding full charge time is greater than 0) and charging gun F is the first charging gun (the corresponding charging parameter is 0), the main controller 108 may determine that the full charge time of charging gun F is the shortest, and use the full charge time of charging gun F as the relative charging parameter of charging gun A.

[0088] When determining the relative charging parameters of charging gun C, the main controller 108 may first determine that the two adjacent charging guns of charging gun C are charging gun B and charging gun D, ​​and when charging gun B and charging gun D are both second charging guns (the corresponding full charging time is greater than 0), the minimum value of the full charging time corresponding to charging gun B and charging gun D is used as the relative charging parameter of charging gun A.

[0089] Step 2032: Obtain weighting coefficients corresponding to the health parameters and the relative charging parameters of the first charging gun.

[0090] The weighting coefficients corresponding to each health parameter and relative charging parameter are used to characterize the degree of influence of the corresponding health parameter or relative charging parameter on the possibility of the first charging gun being called, and can be determined based on test data or expert experience. For example, one or more health parameters include one or two of the number of charging times of the first charging gun and the total output power of the first charging gun. The first weighting coefficient corresponding to the number of charging times of the first charging gun (denoted as K1), the second weighting coefficient corresponding to the total output power of the first charging gun (denoted as K2), and the third weighting coefficient corresponding to the relative charging parameter of the first charging gun (denoted as K3) can be based on the degree of influence of the number of charging times of the first charging gun, the total output power of the first charging gun, and the relative charging parameter of the first charging gun on the possibility of the first charging gun being called.

[0091] In some examples, if the impact of the number of charge cycles of a first charging gun on the likelihood of the first charging gun being called is greater than the impact of the total output power of the first charging gun on the likelihood of the first charging gun number being called, and the impact of the total output power of the first charging gun on the likelihood of the first charging gun number being called is greater than the impact of the relative charging parameters of the first charging gun on the likelihood of the first charging gun number being called, then a first weighting coefficient K1 corresponding to the number of charge cycles of the first charging gun is greater than a second weighting coefficient K2 corresponding to the total output power of the first charging gun, and the second weighting coefficient K2 corresponding to the total output power of the first charging gun is greater than a third weighting coefficient K3 corresponding to the relative charging parameters of the first charging gun, and the sum of K1, K2, and K3 is 1. For example, K1, K2, and K3 may be 0.5, 0.3, and 0.2, respectively. For another example, K1, K2, and K3 may be 0.6, 0.3, and 0.1, respectively. This embodiment of the present application does not limit the values ​​of K1, K2, and K3. This embodiment of the present application uses K1, K2, and K3 as 0.5, 0.3, and 0.2, respectively, for illustrative purposes.

[0092] For example, the one or more health parameters may include one or more of the number of charge cycles of the first charging gun, the total output power of the first charging gun, and the total output power of the charging module corresponding to the first charging gun. A first weighting coefficient K1 corresponding to the number of charge cycles of the first charging gun, a second weighting coefficient K2 corresponding to the total output power of the first charging gun, a third weighting coefficient K3 corresponding to the relative charging parameters of the first charging gun, and a fourth weighting coefficient K4 corresponding to the total output power of the charging module corresponding to the first charging gun may be determined based on the degree of influence of the number of charge cycles of the first charging gun, the total output power of the first charging gun, the relative charging parameters of the first charging gun, and the total output power of the charging module corresponding to the first charging gun on the likelihood of the first charging gun being activated.

[0093] In some examples, if the impact of the number of charge attempts of a first charging gun on the likelihood of the first charging gun being called is greater than the impact of the total output power of the first charging gun on the likelihood of the first charging gun number being called, the impact of the total output power of the first charging gun on the likelihood of the first charging gun number being called is greater than the impact of the relative charging parameters of the first charging gun on the likelihood of the first charging gun number being called, and the impact of the relative charging parameters of the first charging gun on the likelihood of the first charging gun number being called is greater than the impact of the total output power of the charging module corresponding to the first charging gun on the likelihood of the first charging gun number being called, then K1 is greater than K2, K2 is greater than K3, K3 is greater than K4, and the sum of K1, K2, K3, and K4 is 1. For example, K1, K2, K3, and K4 may be 0.4, 0.3, 0.2, and 0.1, respectively. For another example, K1, K2, K3, and K4 may be 0.5, 0.25, 0.15, and 0.1, respectively. The embodiment of the present application does not limit the sizes of K1, K2, K3 and K4. The embodiment of the present application uses K1, K2, K3 and K4 as 0.4, 0.3, 0.2 and 0.1 respectively as an example for illustration.

[0094] For example, the weighting coefficients corresponding to the health parameters and the relative charging parameters of the first charging gun may be pre-stored in a memory. Figure 1 The main controller 108 can read the weighting coefficients corresponding to the health parameters and the relative charging parameters of the first charging gun from a memory, wherein the memory can be a memory in the main controller 108 .

[0095] Step 2033 : Determine a recommended coefficient for each first charging gun based on the weighted coefficients corresponding to the health parameters and the relative charging parameters of the first charging guns, as well as the health parameters and relative charging parameters of the first charging guns.

[0096] The one or more health parameters include one or both of the number of charging times of the first charging gun and the total output power of the first charging gun, the number of charging times of the first charging gun corresponds to a first weighting coefficient K1, the total output power of the first charging gun corresponds to a second weighting coefficient K2, and the relative charging parameter of the first charging gun corresponds to a third weighting coefficient K3, and the number of charging times of the first charging gun, the total output power of the first charging gun, and the relative charging parameter of the first charging gun are denoted as m, n, and z, respectively. For example, Figure 1 As shown, the main controller 108 can calculate K1*m+K2*n+K2*z and use the calculated result as the recommended coefficient for the first charging gun.

[0097] The charging gun recommendation method provided in the embodiment of the present application can determine a recommendation coefficient that takes into account both the health status of the first charging gun and the current charging scenario based on the weighting coefficients corresponding to the health parameters and relative charging parameters and the health parameters and relative charging parameters corresponding to the first charging gun, when the weighting coefficients corresponding to the health parameters and relative charging parameters can accurately reflect the degree of influence of the possibility of the first charging gun being called.

[0098] like Figure 4 As shown in the above Figure 2 Based on the illustrated embodiment, step 204 determines a recommended charging gun from the first charging gun set based on the recommendation coefficient of each first charging gun, the number of second charging guns in the second charging gun set, and the ring topology, and may include the following steps 2041 and 2042 .

[0099] Step 2041: When the number of second charging guns is zero, the first charging gun corresponding to the lowest recommended coefficient is used as the recommended charging gun.

[0100] For example, when all charging guns of the charging stack are in an idle state, the charging gun corresponding to the minimum recommended coefficient among the recommended coefficients of the charging guns can be directly used as the recommended charging gun.

[0101] like Figure 1 As shown, if each of the charging guns A to F is in an idle state and the recommendation coefficient of charging gun A is the lowest, the main controller 108 may use charging gun A as the recommended gun.

[0102] Step 2042: When the number of second charging guns is greater than zero, determine a recommended charging gun from the first charging gun set based on the number of second charging guns and the ring topology.

[0103] like Figure 1 As shown, if at least one of the charging guns A to F is in a charging state, that is, at least one charging gun is a second charging gun, the main controller 108 can determine a recommended charging gun from the first charging gun set according to the number of second charging guns and the position of each second charging gun in the ring topology.

[0104] The charging gun recommendation method provided in the embodiments of this application determines a recommended charging gun based on the recommendation coefficient of each charging gun when the number of second charging guns is zero, and selects the first charging gun with the lowest recommendation coefficient as the recommended charging gun. This method integrates the health of the first charging gun and the current charging scenario, and the optimal recommendation solution is the one where the higher the recommendation coefficient, the lower the recommendation level.

[0105] like Figure 5 As shown in the above Figure 4Based on the illustrated embodiment, determining a recommended charging gun from the first charging gun set based on the number of second charging guns and the ring topology in step 2042 may include the following steps 501 and 502 .

[0106] Step 501: When the number of second charging guns is 1, the first charging gun with the second highest recommendation coefficient among the two adjacent first charging guns of the second charging gun is used as the recommended charging gun.

[0107] It can be understood that the second highest recommendation coefficient refers to the second highest recommendation coefficient among the two adjacent first charging guns of the second charging gun.

[0108] For example, when any charging gun of the charging stack is in a charging state, the recommendation coefficients of two adjacent charging guns in an idle state of the charging gun may be determined first, and the adjacent charging gun with the second highest recommendation coefficient may be used as the recommended charging gun.

[0109] like Figure 1 As shown, if charging gun A among charging guns A to charging gun F is in the charging state and the other charging guns are in the idle state, the main controller 108 can obtain the recommended coefficients of charging guns B and charging guns F adjacent to charging gun A, and when the recommended coefficient of charging gun B is higher than the recommended coefficient of charging gun F, charging gun F will be used as the recommended charging gun.

[0110] Step 502 : When the number of second charging guns is greater than 1, determine a recommended charging gun from the first charging gun set based on a ring topology.

[0111] like Figure 1 As shown, if at least two charging guns among charging guns A to F are in a charging state, that is, at least two charging guns are second charging guns, the main controller 108 can determine a recommended charging gun from the first charging gun set according to the position of each second charging gun in the ring topology.

[0112] The charging gun recommendation method provided in the embodiments of the present application uses the recommendation coefficients of two adjacent first charging guns to recommend the first charging gun with the next highest recommendation coefficient, if the number of second charging guns is one. This method reserves a charging module for power parallel connection for the second charging gun while also taking into account the health of the first charging gun. It is the optimal solution when the higher the recommendation coefficient, the lower the recommendation level.

[0113] like Figure 6 As shown in the above Figure 5 Based on the illustrated embodiment, determining a recommended charging gun from the first charging gun set based on the ring topology in step 502 may include the following steps 601 to 603 .

[0114] Step 601: Based on a ring topology, determine one or more first charging gun groups consisting of first charging guns separated by second charging guns.

[0115] The first charging gun group includes one or more first charging guns that are adjacent to each other in sequence.

[0116] like Figure 1 As shown, if among charging guns A to F, charging guns A and E are the second charging guns, the main controller 108 can determine that charging guns B, C, and D constitute the first charging gun group, and charging gun F constitutes the second charging gun group.

[0117] If charging guns A to F, charging guns A and D are the second charging guns, then the main controller 108 may determine that charging guns B and C constitute the first charging gun group, and charging guns E and F constitute the first charging gun group.

[0118] Step 602: Determine a dispatchable charging gun from the first charging gun group based on the status of the charging module corresponding to each first charging gun in the first charging gun group.

[0119] Among them, the dispatchable charging gun is the first charging gun corresponding to the charging module in the idle state.

[0120] For example, the status of a charging module may include a parallel power state and an idle state. Here, the parallel power state refers to a state in which the charging module outputs power to an adjacent charging module, thereby merging the power of the adjacent charging module. In some examples, if the status of a charging module is idle, the charging gun corresponding to the charging module is determined to be a dispatchable charging gun. If the status of the charging module is parallel power state, the charging gun corresponding to the charging module is determined to be not a dispatchable charging gun.

[0121] like Figure 1 As shown, in a first charging gun group consisting of charging guns B, C, and D, if the charging module corresponding to charging gun B is in parallel power mode and the charging modules corresponding to charging guns C and D are both in idle mode, the main controller 108 can use charging guns C and D as dispatchable charging guns. In another first charging gun group consisting of charging gun F, if the charging modules corresponding to charging gun F are both in idle mode, the main controller 108 can use charging gun F as dispatchable charging gun.

[0122] Step 603 : Determine a recommended charging gun from one or more first charging gun groups based on the number of dispatchable charging guns in each first charging gun group.

[0123] like Figure 1As shown, for example, a charging stack includes a first charging gun group consisting of charging guns B, C, and D, and another first charging gun group consisting of charging gun F, with the charging module corresponding to charging gun B in a parallel power state and the charging modules corresponding to charging guns C, D, and F all in an idle state. The main controller 108 may determine that the number of dispatchable charging guns in the first charging gun group consisting of charging guns B, C, and D is 2, and the number of dispatchable charging guns in the other first charging gun group consisting of charging gun F is 1. Based on the relationship between the number of dispatchable charging guns 2 and the number of dispatchable charging guns 1, the main controller 108 determines a recommended charging gun from the first charging gun group consisting of charging guns B, C, and D.

[0124] The charging gun recommendation method provided in the embodiment of the present application can accurately reflect the usage of the charging guns in the charging stack, because the first charging gun group is composed of one or more first charging guns connected in series and separated by second charging guns. And because of the status of the charging module corresponding to each first charging gun, it can reflect whether the charging module corresponding to the first charging gun is connecting power in parallel to the charging module corresponding to the adjacent second charging gun, thereby excluding first charging guns that are unavailable due to power sharing and accurately determining the dispatchable charging guns. Therefore, the number of dispatchable charging guns in each first charging gun group can accurately reflect the actual charging scenario, and based on the number of dispatchable charging guns in each first charging gun group, the recommended charging gun that meets the actual scenario can be determined from one or more first charging gun groups.

[0125] like Figure 7 As shown in the above Figure 6 Based on the illustrated embodiment, step 603 determines a recommended charging gun from one or more first charging gun groups based on the number of dispatchable charging guns in each first charging gun group, and may include the following steps 6031 to 6032 .

[0126] Step 6031: When the number of schedulable charging guns in one or more first charging gun groups is not zero, determine a recommended charging gun from the one or more schedulable charging guns based on the number of schedulable charging guns in each first charging gun group and the recommendation coefficient of each schedulable charging gun.

[0127] Based on the number of dispatchable charging guns in each first charging gun group and the recommendation coefficient of each dispatchable charging gun, a recommended charging gun is determined from one or more dispatchable charging guns, including: determining a target first charging gun group with the largest number of dispatchable charging guns, and determining the first charging gun with the lowest recommendation coefficient from the target first charging gun group as the recommended charging gun; wherein, the charging module corresponding to the dispatchable charging gun is in an idle state; the first charging gun group includes one or more first charging guns adjacent to each other in sequence.

[0128] Exemplarily, if the charging module corresponding to any first charging gun in any first charging gun group is in an idle state, it is determined that there are schedulable charging guns in one or more first charging gun groups.

[0129] like Figure 1 As shown in the figure, for example, one or more first charging groups include one first charging gun group consisting of charging guns B, charging guns C, and charging guns D, and another first charging gun group consisting of charging gun F. If the charging modules corresponding to one or more of charging guns B, charging guns C, charging guns D, and charging gun F are in an idle state, it is determined that there are schedulable charging guns in the one or more first charging groups. In this case, the main controller 108 can select a recommended charging gun from charging guns B, charging guns C, and charging guns D, or use charging gun D as the recommended charging gun based on the number of idle charging modules among the charging modules corresponding to charging guns B, charging guns C, and charging guns D, and whether the charging module corresponding to charging gun F is idle.

[0130] Step 6032: When the number of dispatchable charging guns in one or more first charging gun groups is zero, determine a recommended charging gun from the one or more first charging gun groups based on the recommendation coefficient of each first charging gun.

[0131] For example, if all charging modules corresponding to the first charging guns in each first charging gun group are in a power-parallel state, it is determined that there are no dispatchable charging guns in one or more first charging gun groups. It is understood that if a recommended charging gun is required when all charging modules corresponding to the first charging guns are in a power-parallel state, the power parallel connection of the recommended first charging gun needs to be disconnected, that is, the switch between the recommended charging gun and the second charging gun needs to be controlled.

[0132] like Figure 1 As shown in the figure, for example, one or more first charging groups include one first charging gun group consisting of charging guns B and charging guns C, and another first charging gun group consisting of charging gun F. If the charging modules corresponding to charging guns B, charging guns C, and charging guns F are all in parallel power state, it is determined that there are no dispatchable charging guns in the one or more first charging groups. In this case, the main controller 108 can directly select a recommended charging gun from charging guns B, charging guns C, and charging guns F based on their recommendation coefficients. For example, if charging gun C has the lowest recommendation coefficient among charging guns B, charging guns C, and charging guns F, the main controller 108 will select charging gun C as the recommended charging gun.

[0133] The charging gun recommendation method provided in the embodiments of the present application determines a recommended charging gun from one or more schedulable charging guns based on the number of schedulable charging guns in each first charging gun group and the recommendation coefficient of each schedulable charging gun, if one or more first charging gun groups have schedulable charging guns. If one or more first charging gun groups do not have schedulable charging guns, the method determines a recommended charging gun from one or more first charging gun groups based on the recommendation coefficient of each first charging gun. In this way, regardless of whether there are schedulable charging guns, a recommended charging gun that meets the actual scenario and takes health into consideration can be determined to a certain extent.

[0134] like Figure 8 As shown in the above Figure 7 On the basis of the illustrated embodiment, determining a recommended charging gun from one or more schedulable charging guns based on the number of schedulable charging guns in each first charging gun group and the recommendation coefficient of each schedulable charging gun in step 6031 may include the following steps 801 and 802.

[0135] Step 801: Determine a target charging gun group based on the number of dispatchable charging guns in each first charging gun group.

[0136] Among them, the target charging gun group is the first charging gun group corresponding to the largest number of dispatchable charging guns.

[0137] Exemplarily, the target charging gun group may include one or more first charging gun groups. This embodiment of the application does not limit the number of first charging gun groups in the target charging gun group.

[0138] like Figure 1 As shown, taking one or more first charging gun groups including a first charging gun group consisting of charging guns B and charging guns C, and another first charging gun group consisting of charging guns E and charging guns F as an example, if the number of schedulable charging guns in a first charging gun group consisting of charging guns B and charging guns C is 2, and the number of schedulable charging guns in another first charging gun group consisting of charging guns E and charging guns F is also 2, the main controller 108 can use a first charging gun group consisting of charging guns B and charging guns C, and another first charging gun group consisting of charging guns E and charging gun F (2 first charging groups) as target charging gun groups.

[0139] If the number of schedulable charging guns in a first charging gun group consisting of charging guns B and charging guns C is 2, and the number of schedulable charging guns in another first charging gun group consisting of charging guns E and charging guns F is 1 (the charging module corresponding to charging gun F is in parallel power state), then the main controller 108 can use a first charging gun group (a first charging group) consisting of charging guns B and charging guns C as the target charging gun group.

[0140] Step 802 : Determine a recommended charging gun from the target charging gun group based on the number of schedulable charging guns in the target charging gun group, or based on the number of schedulable charging guns in the target charging gun group and a recommendation coefficient of each schedulable charging gun.

[0141] For example, Figure 1 As shown, the main controller 108 can determine whether the number of schedulable charging guns in the target charging gun group is odd or even, and use different judgment rules and recommendation coefficients of each schedulable charging gun to determine the recommended charging gun from the target charging gun group.

[0142] The charging gun recommendation method provided in the embodiment of the present application is such that, since the target charging gun group is the first charging group corresponding to the maximum number of schedulable charging guns, selecting the recommended charging gun from the target charging gun group can reserve the charging module for power parallel connection for the recommended charging gun to the greatest extent. Therefore, based on the number of schedulable charging guns in the target charging gun group, or based on the number of schedulable charging guns in the target charging gun group and the recommendation coefficient of each schedulable charging gun, it is possible to determine the recommended charging gun from the target charging gun group that meets the actual scenario and takes into account the health condition while meeting the user's charging power requirements as much as possible.

[0143] In some embodiments, the target charging gun group corresponds to a first charging gun group. Figure 9 As shown in the above Figure 8 Based on the illustrated embodiment, step 802 determines the recommended charging gun from the target charging gun group based on the number of dispatchable charging guns in the target charging gun group, or based on the number of dispatchable charging guns in the target charging gun group and the recommendation coefficient of each dispatchable charging gun, and may include the following steps 8021 and 8022.

[0144] Step 8021: When the number of dispatchable charging guns in the target charging gun group is odd and greater than 1, a dispatchable charging gun in the middle of the target charging gun group is used as a recommended charging gun.

[0145] like Figure 1 As shown, if the target charging gun group includes charging gun B, charging gun C, and charging gun D, ​​the main controller 108 may use charging gun C as the recommended charging gun.

[0146] Step 8022: When the number of schedulable charging guns in the target charging gun group is even and greater than or equal to 2, select the schedulable charging gun with the lower recommendation coefficient from the two schedulable charging guns in the middle position of the target charging gun group as the recommended charging gun.

[0147] It can be understood that if the number of schedulable charging guns in the target charging gun group is 1, the schedulable charging gun in the target charging gun group is used as the recommended charging gun.

[0148] like Figure 1As shown, if the target charging gun group includes charging guns B and charging guns C, and the recommendation coefficient of charging gun B is greater than the recommendation coefficient of charging gun C, the main controller 108 may use charging gun B as the recommended charging gun.

[0149] If the target charging gun group includes charging guns B, C, D, and E, the main controller 108 may select a recommended charging gun from charging guns C and D. If the recommendation coefficient of charging gun C is greater than the recommendation coefficient of charging gun D, ​​the main controller 108 may select charging gun C as the recommended charging gun.

[0150] The charging gun recommendation method provided in the embodiment of the present application is that since the target charging gun group is the first charging gun group corresponding to the maximum number of schedulable charging guns, selecting the recommended charging gun from the target charging gun group can maximize the reserved charging modules for power parallel connection for the recommended charging guns, thereby avoiding the occurrence of power islands. Furthermore, when the number of schedulable charging guns in the target charging gun group is an odd number and greater than 1, a schedulable charging gun in the middle position of the target charging gun group is used as the recommended charging gun; when the number of schedulable charging guns in the target charging gun group is an even number and greater than or equal to 2, the schedulable charging gun with a higher recommendation coefficient is selected from the two schedulable charging guns in the middle position of the target charging gun group as the recommended charging gun. This scheme is the optimal charging gun recommendation scheme, which can maximize the reserved charging modules for the recommended charging guns, improve resource utilization, system energy efficiency, and extend the service life of the charging guns.

[0151] In some embodiments, the target charging gun group corresponds to multiple first charging gun groups. Figure 10 As shown in the above Figure 8 Based on the illustrated embodiment, step 802 determines the recommended charging gun from the target charging gun group based on the number of dispatchable charging guns in the target charging gun group, or based on the number of dispatchable charging guns in the target charging gun group and the recommendation coefficient of each dispatchable charging gun, and may include the following steps 8023 and 8024.

[0152] Step 8023: When the number of schedulable charging guns in each first charging gun group corresponding to the target charging gun group is an odd number and greater than 1, extract a schedulable charging gun in the middle position of each first charging gun group to obtain a first candidate charging gun set, and use the candidate charging gun with the lowest recommendation coefficient in the first candidate charging gun set as the recommended charging gun.

[0153] For example, consider a charging stack consisting of eight charging modules connected in a ring topology, corresponding to charging guns A through H. If charging guns A and E are second-tier charging guns, and the remaining charging guns are all first-tier, schedulable charging guns, then charging gun C, located in the middle of the first group of charging guns consisting of charging guns B, C, and D, can be selected as a candidate charging gun. Similarly, charging gun G, located in the middle of the first group of charging guns consisting of charging guns F, G, and H, can be selected as a candidate charging gun, resulting in a first candidate charging gun set that includes charging guns C and G. The charging gun with the lowest recommendation coefficient between charging guns C and G is selected as the recommended charging gun. For example, if charging gun G's recommendation coefficient is higher than that of charging gun C, then charging gun C is selected as the recommended charging gun.

[0154] Step 8024: When the number of schedulable charging guns in each first charging gun group corresponding to the target charging gun group is an even number and greater than 2, extract the two schedulable charging guns in the middle position of each first charging gun group to obtain a second candidate charging gun set; and use the candidate charging gun with the lowest recommendation coefficient in the second candidate charging gun set as the recommended charging gun.

[0155] For example, consider a charging stack consisting of 10 charging modules connected in a ring topology, corresponding to charging guns A through J. If charging guns A and F are second-tier charging guns, and the remaining charging guns are all first-tier, schedulable guns, then two middle-position charging guns, C and D, can be selected as candidate charging guns from the first group of charging guns consisting of B, C, D, and E. Two middle-position charging guns, H and I, can be selected as candidate charging guns from the first group of charging guns consisting of G, H, I, and J. This yields a second candidate charging gun set consisting of charging guns C, D, H, and I. The recommended charging gun is then selected as the one with the lowest recommendation coefficient among C, D, H, and I. For example, if charging gun D has the lowest recommendation coefficient among C, D, H, and I, then D is selected as the recommended charging gun.

[0156] In the charging gun recommendation method provided in the embodiments of the present application, since the target charging gun group is the first charging gun group corresponding to the maximum number of schedulable charging guns, selecting the recommended charging gun from the target charging gun group can maximize the number of charging modules reserved for power parallel connection for the recommended charging guns, thereby avoiding the occurrence of power islands. Furthermore, if the number of schedulable charging guns in each first charging gun group corresponding to the target charging gun group is an odd number and greater than 1, the schedulable charging gun with the lowest recommendation coefficient among the schedulable charging guns in the middle of each first charging gun group is selected as the recommended charging gun. If the number of schedulable charging guns in each first charging gun group corresponding to the target charging gun group is an even number and greater than 2, the schedulable charging gun with the lowest recommendation coefficient among the two schedulable charging guns in the middle of each first charging gun group is selected as the recommended charging gun. In the case where a larger recommendation coefficient indicates a lower recommendation level, this solution is the optimal charging gun recommendation solution, which can maximize the number of charging modules reserved for power parallel connection for the recommended charging guns, thereby improving resource utilization, system energy efficiency, and extending the service life of the charging guns.

[0181] Step 1123: Is the number of dispatchable charging guns in each first charging gun group corresponding to the target charging gun group greater than 1? If so, proceed to step 1124; otherwise, proceed to step 1125.

[0182] Step 1124 : extract a dispatchable charging gun in the middle position of each first charging gun group to obtain a first candidate charging gun set, and use the candidate charging gun with the lowest recommendation coefficient in the first candidate charging gun set as the recommended charging gun.
