Description

Technical Field

[0001] The present application relates to the field of new energy charging technology, and in particular to a charging power distribution method, an electronic device, and a computer-readable storage medium. Background Art

[0002] With the popularity of new energy vehicles, how to allocate higher charging power to vehicles after connecting to charging guns has become a pain point for new energy charging. Among them, the mainstream architectures composed of multiple charging modules include matrix allocation architecture and ring allocation architecture, and the cost-effective ring allocation architecture has been more widely used. However, the randomness of car owners in choosing parking spaces leads to randomness in the selection of charging modules in the ring charging module. Due to the limitations of the ring charging architecture itself, it is easily affected by charging modules in other locations. Under the premise of random allocation of charging modules, it is easy for some charging guns to have low power, resulting in unreasonable charging power distribution. In view of this, how to improve the rationality of charging power distribution has become an urgent problem to be solved. Summary of the Invention

[0003] The main technical problem solved by this application is to provide a charging power distribution method, an electronic device and a computer-readable storage medium, which can improve the rationality of charging power distribution.

[0004] In order to solve the above technical problems, the first aspect of the present application provides a charging power distribution method, which is applied to a ring charging module, wherein the ring charging module includes multiple charging modules connected in sequence end to end, and each charging module corresponds to a charging gun. The method includes: obtaining idle charging modules, and determining the idle partitions corresponding to all idle charging modules; wherein the idle partitions are separated by working partitions, and the working partitions include all charging modules occupied by a single charging gun; in response to obtaining the idle partition, based on the idle partition and the working partitions on both sides of the idle partition, selecting a target module from the charging modules of the idle partition; in response to not obtaining the idle partition, selecting a target module from the working partition based on the idle power corresponding to all the working partitions; in response to the vehicle being connected to the charging gun corresponding to the target module and obtaining the required power of the vehicle, determining the charging power of the vehicle based on the required power and the power that can be allocated by at least part of the charging module.

[0005] To solve the above technical problems, the second aspect of the present application provides an electronic device, which includes: a memory and a processor coupled to each other, wherein the memory stores program data, and the processor calls the program data to execute the method described in the first aspect above.

[0006] In order to solve the above technical problems, the third aspect of the present application provides a computer-readable storage medium on which program data is stored. When the program data is executed by a processor, the method described in the first aspect is implemented.

[0007] In the above scheme, the ring-shaped charging module includes charging modules connected in sequence and connected end to end. Each charging module corresponds to a charging gun, and each charging gun occupies at least the corresponding charging module during operation. Idle charging modules in the ring-shaped charging module are obtained, and an idle partition consisting of all idle charging modules is determined. All charging modules occupied by a single charging gun correspond to a working partition, and an idle partition is separated by a working partition, each containing at least one charging module. When an idle partition is obtained, a suitable charging module is selected as a target module from the charging modules in the idle partition based on the idle partition and the working partitions on either side of the idle partition. When an idle partition is available in the ring-shaped charging module, the target module is selected from the idle partition based on the usage of the charging modules in the idle partition and the working partitions on either side of the idle partition, thereby reducing the probability of inefficient allocation of idle charging modules due to both charging modules on either side of the target module being occupied. When no idle partition is available, a charging module is selected from the working partition as the target module based on the idle power corresponding to all working partitions. When no idle partition is available in the ring-shaped charging module, a target module that maximizes power is selected from the working partition based on the excess idle power of the working partition, thereby ensuring charging power. When the vehicle is connected to the charging gun corresponding to the target module and obtains the required power of the vehicle, at least the output power of the target module is provided to the charging gun. Based on the required power and the power that can be allocated by at least part of the charging module, a decision is made on whether to allocate other charging modules, thereby determining the charging power of the vehicle, so that the total power of the ring charging module can be fully allocated, and the rationality of the charging power allocation is improved.

[0018] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of them, and different implementation methods can be adaptively combined. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0019] The terms "system" and "network" are often used interchangeably in this document. The term "and / or" is simply a description of an association between related objects, indicating that three possible relationships exist. For example, "A and / or B" can mean: A exists alone, A and B exist simultaneously, or B exists alone. Furthermore, the character " / " generally indicates that the related objects are in an "or" relationship. Furthermore, "multiple" in this document means two or more than two.

[0020] The charging power allocation method provided in this application is applied to a ring-shaped charging module, which includes multiple charging modules connected end to end, each with a corresponding charging gun. This charging power allocation method is used to select an appropriate charging module from the ring-shaped charging module and allocate charging power that matches the vehicle's required power. The corresponding execution entity is a processing unit capable of data processing.

[0021] It should be noted that the ring charging module includes charging modules connected in sequence and end to end. Each charging module corresponds to a charging gun, and each charging gun occupies at least the corresponding charging module when in operation. Among them, the ring charging module includes multiple charging modules, and all charging modules correspond to busbars. Each charging module is directly connected to the corresponding charging gun. A busbar switch is provided between adjacent charging modules, and the busbar switch has positive and negative polarity. The number of charging modules in the ring charging module can be any integer, and this application does not impose specific restrictions on this. For ease of understanding, this application is described in detail as if the ring charging module includes 12 charging modules.

[0022] See also Figure 1 , Figure 1 This is a schematic diagram of an application scenario of an embodiment of the matrix charging module of the present application. Taking 12 charging modules as an example to construct a matrix charging module according to the matrix distribution architecture, each charging gun in the matrix distribution architecture requires 24 bus tie switches, and 12 charging guns require 288 switches, resulting in high costs. Figure 1 The diagram only shows the switches corresponding to one polarity. The switches for the other polarity are arranged in the same way. Figure 1 same.

[0023] See also Figure 2 , Figure 2 This is a schematic diagram of an application scenario of an embodiment of the ring charging module of the present application, wherein the ring charging module includes 12 charging modules, namely Figure 2 As shown in the figure, each charging module corresponds to its own charging gun. When the charging gun is connected to the vehicle and working, the charging gun occupies at least the corresponding charging module. A busbar switch is provided between adjacent charging modules. A ring charging module composed of 12 charging guns requires a total of 24 busbar switches, which is relatively low in cost. Figure 2 The diagram only shows the switches corresponding to one polarity. The switches for the other polarity are arranged in the same way. Figure 2 same.

[0024] While the ring-based allocation architecture offers cost advantages, it also has inherent disadvantages in the allocation and scheduling of charging modules. For example, when charging with 12-gun and 2-gun vehicles uses a certain number of charging modules, if a vehicle uses 1-gun for charging, the channels around 1-gun are interrupted by 12-gun and 2-gun. Therefore, even if other modules are idle, 1-gun cannot call modules 3-11, resulting in resource waste. This is also a natural disadvantage of the ring-based allocation architecture. Therefore, it is necessary to rationally plan the allocation of charging modules in the ring charging module to reduce resource waste caused by randomness.

[0025] See also Figure 3 , Figure 3This is a flow chart of an embodiment of a charging power distribution method of the present application, which includes:

[0026] S101: Obtain idle charging modules and determine idle partitions corresponding to all idle charging modules; wherein the idle partitions are separated by working partitions, and the working partitions include all charging modules occupied by a single charging gun.

[0027] Specifically, the idle charging modules in the ring charging module are obtained, and the idle partition composed of all the idle charging modules is determined, wherein all the charging modules occupied by a single charging gun correspond to a working partition, the idle partition is separated by the working partition, and the idle partition includes at least one charging module.

[0028] It is understandable that when a vehicle is connected to a charging gun, the vehicle's required power should be met as much as possible. When the vehicle's required power exceeds the output power of a single charging module, if other charging modules adjacent to the charging module corresponding to the charging gun are idle, a single charging gun will occupy more than at least two charging modules, that is, the charging gun will occupy the corresponding charging module and at least one charging module adjacent to it.

[0029] In one embodiment, all working charging guns in the ring charging module are obtained, the working partition occupied by each working charging gun is determined, and the idle partitions composed of charging modules between the working partitions are determined.

[0030] In one embodiment, all unoccupied charging modules in the ring charging module are obtained, and it is determined whether the unoccupied charging modules are continuous. The continuous and idle charging modules between the working partitions are regarded as idle partitions, and the charging modules that exist alone between the working partitions are regarded as idle partitions.

[0031] It is understandable that when all charging modules in the ring charging module are occupied, the ring charging module does not include any idle partitions.

[0032] S102: In response to obtaining a free partition, a target module is selected from charging modules of the free partition based on the free partition and the working partitions on both sides of the free partition.

[0033] Specifically, when an idle partition is obtained, based on the idle partition and the working partitions on both sides of the idle partition, a suitable charging module is selected from the charging modules of the idle partition as the target module.

[0034] It can be understood that when there is an idle partition in the circular charging module, the target module is selected from the idle partition according to the usage of the charging modules in the idle partition and the working partitions on both sides of the idle partition, so as to reduce the probability of difficulty in effectively allocating idle charging modules due to the charging modules on both sides of the target module being occupied.

[0035] In one embodiment, the number of idle charging modules in an idle partition and the number of active charging modules in working partitions on either side of the idle partition are obtained. If no working partition exists on either side of the idle partition, the active number is zero. Based on the idle number of each idle partition, candidate idle partitions are determined. Based on the active numbers of the working partitions on both sides, a power supply module is selected from the candidate idle partitions as a target module.

[0036] In one embodiment, the total idle power of all charging modules in an idle partition and the idle power of charging modules in working partitions on both sides of the idle partition are obtained. Based on the total idle power of each idle partition and the idle power of the working partitions on both sides, candidate idle partitions are determined. Based on the idle power of the working partitions on both sides, a power supply module is selected from the candidate idle partitions as a target module.

[0037] In some implementation scenarios, the number of idle charging modules in an idle partition and the number of working charging modules in the working partitions on both sides of the idle partition are obtained. The idle partition with the largest number of idle modules is selected as a candidate idle partition. If multiple candidate idle partitions are obtained, the idle partition with the fewest working working partitions on both sides is selected as the final candidate idle partition. The side of the working partition with the fewest working working modules adjacent to the candidate idle partition is selected as the target side. If the candidate idle partition includes multiple charging modules, the charging modules separated from the working partition are selected from the target side as the target modules.

[0038] It should be noted that when the number of working charging modules in the working partitions on both sides of the candidate idle partition is equal, the charging module separated from the working partition is selected as the target module according to the preset rules, wherein the preset rules include but are not limited to clockwise selection, counterclockwise selection, selection from the side with smaller identification number or selection from the side with larger identification number. When the candidate idle partition includes only one charging module, the corresponding charging module can be used as the target module.

[0039] In some implementations, the total idle power of all charging modules within an idle partition and the idle power of charging modules within working partitions on either side of the idle partition are obtained. The idle partition with the largest total idle power and the sum of the idle powers of its working partitions on either side is selected as a candidate idle partition. A target side corresponding to the working partition with the largest idle power adjacent to the candidate idle partition is determined. If the candidate idle partition includes multiple charging modules, a charging module separated from the working partition is obtained from the target side as the target module.

[0040] It should be noted that when the idle power in the working partitions on both sides of the candidate idle partition is the same, the charging module separated from the working partition is selected as the target module according to the preset rules, wherein the preset rules include but are not limited to clockwise selection, counterclockwise selection, selection from the side with smaller identification number or selection from the side with larger identification number. When the candidate idle partition includes only one charging module, the corresponding charging module can be used as the target module.

[0041] It is understood that when the number of free modules in the candidate free partitions exceeds the threshold, the target side can be used as a reference to select the central charging module in the free partition as the target module, or charging modules from the target side can be selected as the target modules according to a first interval. When the number of free modules in the candidate free partitions does not exceed the threshold, charging modules from the target side can be selected as the target modules according to a second interval. The first interval is greater than the second interval.

[0042] S103 : In response to not obtaining an idle partition, selecting a target module from the working partition based on the idle powers corresponding to all working partitions.

[0043] Specifically, when no idle partition is obtained, a charging module is selected from the working partition as a target module based on the idle powers corresponding to all working partitions.

[0044] It is understandable that when there is no idle partition in the ring charging module, a target module that can maximize power is selected from the working partition according to the surplus idle power of the working partition, thereby ensuring the charging power.

[0045] In one embodiment, the unused idle power of each working partition in the ring charging module is obtained, the working partition with the highest idle power is obtained, and the charging module at the edge of the working partition with the highest idle power is selected as the target module.

[0046] In one embodiment, the sum of the idle powers of every two adjacent working partitions in the ring charging module is obtained as the total releasable power, and the charging module at the junction of the two working partitions with the largest releasable total power is selected as the target module.

[0047] In some implementation scenarios, the unused idle power of each working partition in the ring charging module is obtained, the working partition with the highest idle power is obtained as the candidate partition, the idle power of the working partitions on both sides of the candidate partition is determined, the side with larger idle power is taken as the target side, and the charging module at the edge of the target side is selected from the candidate partition as the target module.

[0048] In some implementation scenarios, the sum of the idle powers of every two adjacent working partitions in the ring charging module is obtained as the total releasable power, the charging modules corresponding to the intersection of the two working partitions with the largest releasable total power are taken as candidate modules, and the candidate modules in the working partitions with larger idle power are taken as target modules.

[0049] S104: In response to the vehicle being connected to the charging plug corresponding to the target module and obtaining the required power of the vehicle, determining the charging power of the vehicle based on the required power and the power that can be allocated by at least part of the charging module.

[0050] Specifically, when the vehicle is connected to the charging gun corresponding to the target module and obtains the required power of the vehicle, at least the output power of the target module is provided to the charging gun. Based on the required power and the power that can be allocated by at least part of the charging module, a decision is made on whether to allocate other charging modules, thereby determining the charging power of the vehicle, so that the total power of the ring charging module can be fully allocated, and the rationality of the charging power allocation is improved.

[0051] In one embodiment, the required power of the vehicle is obtained, and based on the required power and the power that can be allocated to the target module and other charging modules on both sides of the target module, it is determined whether to allocate other charging modules other than the target module to the vehicle, thereby determining the charging power of the vehicle based on the allocated charging modules.

[0052] In some implementation scenarios, the vehicle's required power is obtained. If the target module's output power can meet the required power, the required power is used as the vehicle's charging power. If the target module's output power does not meet the required power, it is determined whether the charging modules on both sides of the target module can provide surplus power. If so, other charging modules are deployed. Otherwise, only the target module is deployed for the vehicle.

[0053] In one embodiment, the vehicle's required power and the output power of the target module are obtained, the partition in which the target module is located is determined, and based on the vehicle's required power, the output power of the target module and the partition in which the target module is located, it is determined whether to allocate other charging modules in the partition in which the target module is located or the vector partition to the vehicle, thereby determining the vehicle's charging power based on the allocated charging module.

[0054] It can be understood that when the vehicle is connected to the charging gun corresponding to the target module, the required power can be determined after reading the vehicle's battery management system information. After reading the information, if the target module is in the working partition, the target module will be released so that the target module can be assigned to the corresponding charging gun, and the working partition in the ring charging module will be updated after releasing the target module.

[0055] In some implementation scenarios, the vehicle's required power is obtained. If the target module's output power can meet the required power, the required power is used as the vehicle's charging power, and the target module is deployed for power supply. If the target module's output power does not meet the required power, the partition in which the target module is located is determined, and when the target module is in an idle partition, an idle charging module is deployed. Alternatively, when the target module is in a working partition, it is determined whether to deploy other charging modules from adjacent working partitions according to the allocation principle of maximizing power utilization.

[0056] In the above scheme, the ring-shaped charging module includes charging modules connected in sequence and connected end to end. Each charging module corresponds to a charging gun, and each charging gun occupies at least the corresponding charging module during operation. Idle charging modules in the ring-shaped charging module are obtained, and an idle partition consisting of all idle charging modules is determined. All charging modules occupied by a single charging gun correspond to a working partition, and an idle partition is separated by a working partition, each containing at least one charging module. When an idle partition is obtained, a suitable charging module is selected as a target module from the charging modules in the idle partition based on the idle partition and the working partitions on either side of the idle partition. When an idle partition is available in the ring-shaped charging module, the target module is selected from the idle partition based on the usage of the charging modules in the idle partition and the working partitions on either side of the idle partition, thereby reducing the probability of inefficient allocation of idle charging modules due to both charging modules on either side of the target module being occupied. When no idle partition is available, a charging module is selected from the working partition as the target module based on the idle power corresponding to all working partitions. When no idle partition is available in the ring-shaped charging module, a target module that maximizes power is selected from the working partition based on the excess idle power of the working partition, thereby ensuring charging power. When the vehicle is connected to the charging gun corresponding to the target module and obtains the required power of the vehicle, at least the output power of the target module is provided to the charging gun. Based on the required power and the power that can be allocated by at least part of the charging module, a decision is made on whether to allocate other charging modules, thereby determining the charging power of the vehicle, so that the total power of the ring charging module can be fully allocated, and the rationality of the charging power allocation is improved.

[0057] See also Figure 4 , Figure 4 This is a flow chart of another embodiment of the charging power distribution method of the present application. The method is applied to a ring charging module, which is deployed in a parking lot IoT system. The charging gun is matched with a parking space in the parking lot IoT system. The parking lot IoT system is equipped with an entrance display module and a parking space management module. The method includes:

[0058] S201: Obtain idle charging modules and determine idle partitions corresponding to all idle charging modules; wherein the idle partitions are separated by working partitions, and the working partitions include all charging modules occupied by a single charging gun.

[0059] Specifically, the idle charging modules in the ring charging module are obtained, and the idle partition composed of all the idle charging modules is determined, wherein the idle partition includes unoccupied charging modules, and all charging modules occupied by a single charging gun correspond to a working partition. The idle partition is separated by the working partition, and the idle partition includes one charging module or multiple consecutive charging modules.

[0060] It is understandable that when all charging modules in the ring charging module are occupied, the ring charging module does not include any idle partitions.

[0061] S202: In response to obtaining a free partition, a target module is selected from charging modules of the free partition based on the free partition and the working partitions on both sides of the free partition.

[0062] Specifically, when an idle partition is obtained, based on the idle partition and the working partitions on both sides of the idle partition, a suitable charging module is selected from the charging modules of the idle partition as the target module.

[0063] In one embodiment, based on the idle partition and the working partitions on both sides thereof, a target module is selected from the charging modules of the idle partition, including: obtaining the idle number of charging modules in each idle partition, taking the idle partition with the largest idle number as the target idle partition, obtaining the idle power corresponding to the working partitions on both sides of the target idle partition as the releasable power; based on the idle number and the releasable power, selecting the charging module from the target idle partition as the target module.

[0064] Specifically, the total number of charging modules in each idle partition is obtained to determine the idle number. The idle partition with the largest idle number is selected as the target idle partition. The idle power corresponding to the working partitions on both sides of the target idle partition is obtained as the surplus releasable power of the idle partitions on both sides. If there are multiple idle partitions with the largest idle number, the idle partition with the highest releasable power is selected as the final target idle partition. This allows for precise screening of target idle partitions based on the idle number of charging modules in the idle partition and the idle power of the working partitions on both sides.

[0065] Furthermore, based on the idle quantity and releasable power in the target idle partition, the charging modules in the target idle partition are screened, and the charging module with the highest matching degree is selected from the target idle partition as the target module, thereby improving the accuracy of the target module.

[0066] It should be noted that, based on the idle number and the releasable power, the charging module is selected as the target module from the target idle partition, including: in response to the idle number of the target idle partition exceeding the quantity threshold, the side with larger releasable power is taken as the target side, and the charging module is selected as the target module from the target idle partition from the target side according to the first quantity interval; in response to the idle number of the target idle partition not exceeding the quantity threshold, the side with larger releasable power is taken as the target side, and the charging module is selected as the target module from the target idle partition from the target side according to the second quantity interval; wherein the first quantity interval is greater than the second quantity interval.

[0067] Specifically, when the number of idle modules in the target idle partition exceeds the quantity threshold, the side with larger release power is obtained and used as the target side. Starting from the target side, the charging module is selected from the target idle partition as the target module according to the first quantity interval, thereby controlling the position of the target module screened on one side in the idle partition, ensuring the interval between the target module and the working partition, facilitating the subsequent allocation of the charging module to maximize power, and avoiding the target module dividing the longer idle partition into more fragmented areas.

[0068] It can be understood that when the idle number of the target idle partition does not exceed the quantity threshold, the side with larger releasable power is taken as the target side, and the charging module is selected as the target module from the target idle partition according to the second quantity interval with the target side as the starting point, so that when the idle number is small, the charging module is selected at the second quantity interval, wherein the first quantity interval is greater than the second quantity interval, and the target module is set on the side with larger releasable power to facilitate power maximization.

[0069] In one specific implementation scenario, a target idle partition is determined, and then, based on the releasable power of the working partitions adjacent to the left and right of the target idle partition, the side with greater releasable power is selected as the target side. For example, if the module number increases from the left side to the right side until it reaches the maximum value and then resets, and the module number decreases from the right side to the left side until it reaches the minimum value and then resets, if the number of idle partitions in the partition exceeds a threshold and the releasable power on the left side is greater, the charging module with the module number +2 on the left side is selected as the target module. If the releasable power on the right side is greater, the charging module with the module number -2 on the left side is selected as the target module. Thus, when the number of idle partitions exceeds the threshold, the target module is selected with one charging module interval, so that more charging modules can be more conveniently called after the charging gun corresponding to the target module is working. If the number of idle modules in the partition does not exceed the quantity threshold, the charging module with module number +1 on the left is selected as the target module. If the releasable power on the right is large, the charging module with module number -1 on the right is selected as the target module. Therefore, when the number of idle modules does not exceed the quantity threshold, the target module is set to be adjacent to the working partition with larger releasable power, so that after the charging gun corresponding to the target module works, there is a higher probability that the adjacent working partition can release the charging module for use by the charging gun corresponding to the target module.

[0070] S203 : In response to not obtaining an idle partition, selecting a target module from the working partition based on the idle powers corresponding to all working partitions.

[0071] Specifically, when no idle partition is obtained, a charging module is selected from the working partition as a target module based on the idle powers corresponding to all working partitions.

[0072] In one embodiment, a target module is selected from a working partition based on the idle power corresponding to all working partitions, including: determining the total releasable idle power between every two adjacent working partitions based on the idle power corresponding to all working partitions; and selecting a target module from a working partition based on the total releasable power.

[0073] Specifically, the idle power corresponding to each working partition is obtained, the sum of the idle powers of every two adjacent working partitions is used as the total releasable power, and a charging module is selected from the working partition as the target module according to the total releasable power.

[0074] It can be understood that the two working partitions with the largest total power that can be released are determined, and the corresponding charging module is selected as the target module from the intersection of the two corresponding working partitions, so that the power loss of the original working partition can be reduced after the target module is released, and after the charging gun corresponding to the target module works, there is a higher probability that the adjacent working partition can release the charging module for use by the charging gun corresponding to the target module.

[0075] In some implementation scenarios, a target module is selected from a working partition based on the total releasable power, including: obtaining two working partitions with the largest total releasable power as candidate partitions; and selecting a target module from two adjacent charging modules between the candidate partitions based on the idle power within the candidate partitions.

[0076] Specifically, the total releasable power corresponding to every two adjacent working partitions is obtained, the two working partitions with the largest releasable total power are selected as candidate partitions, the idle power in each candidate partition is determined, and according to the size of the idle power, the charging module adjacent to the other candidate partition in the candidate partition with larger idle power is selected as the target module from the two adjacent charging modules between the candidate partitions. This can minimize the power loss of the original working partition after the target module is released, and there is a high probability that the adjacent working partition can release the charging module after the charging gun corresponding to the target module is working, so that the charging gun corresponding to the target module can be used.

[0077] For illustration purposes, see Figure 5 , Figure 5 This is a schematic diagram of an application scenario for determining an embodiment of the target module of this application. Taking the output power of each charging module as 40 kilowatts (KW), 2 guns occupy modules 1 to 3 to form a working partition, 5 guns occupy modules 4 to 6 to form a working partition, 8 guns occupy modules 7 to 9 to form a working partition, 10 guns occupy module 10 to form a working partition, and 11 guns occupy modules 11 to 12 to form a working partition. Among them, 2 guns have an idle power of 10KW, 5 guns have an idle power of 12KW, and 8 guns have an idle power of 5KW; 10 guns have an idle power of 0KW, and 11 guns have an idle power of 2KW. In theory, each charging gun can release a charging module as long as it has idle power.

[0078] Furthermore, the difference between the actual power occupied in the working partition and the output power is compared to obtain the idle power of the working partition, thereby determining the total power that can be released in the two adjacent working partitions. According to the matching rules of the adjacent charging guns, the total power that can be released and the number of releasable modules are calculated again by crossing the two adjacent charging guns. Figure 5 Guns 2 and 5 have 22 kW of idle power, theoretically allowing the release of two charging modules. Guns 5 and 8 have 17 kW of idle power, theoretically allowing the release of two charging modules. Guns 8 and 10 have 5 kW of idle power, theoretically allowing the release of one idle module. Guns 10 and 11 have 2 kW of idle power, theoretically allowing the release of one charging module. Guns 11 and 2 have 12 kW of idle power, theoretically allowing the release of two charging modules. Therefore, in this scenario, the working partitions corresponding to guns 2 and 5 are selected as candidate partitions. Since gun 5 has greater idle power, module 4 is selected as the target module from the working partition corresponding to gun 5.

[0079] Understandably, by determining the available power within the two candidate zones, the charging module with greater available power is prioritized as the target module, ensuring maximum resource utilization. The target module is then released. Once the vehicle connects to the target module's corresponding charging station, the battery management system determines the power requirements and decides whether to allocate a module in the other candidate zone that is operating at less than full power, maximizing the utilization of limited power.

[0080] S204: Acquire the target parking space matched by the target module, and transmit the target parking space to the entrance display module; wherein, when the vehicle enters the preset range of the target parking space, the parking space management module releases the target parking space.

[0081] Specifically, the target module obtains the parking space matched by the charging gun in the parking lot IoT system as the target parking space. This target parking space is then transmitted to the entrance display module, where a prompt message is generated, instructing the vehicle to proceed to the target parking space. When the corresponding vehicle enters the preset range of the target parking space, the parking space management module releases the target parking space, enabling more intelligent allocation and management of parking spaces.

[0082] It is understood that the entrance display module can recognize the vehicle's license plate and receive the target parking space display prompt information. The parking space management module corresponds to a terminal for managing parking spaces, and each terminal manages at least one parking space. The parking lot IoT system can be configured with at least one set of entrance display modules and multiple sets of parking space management modules based on the actual situation within the parking lot. This application does not impose specific limitations on this.

[0083] For illustration purposes, see Figure 6 , Figure 6 This is a schematic diagram of the application scenario of the unified implementation method of the parking lot IoT system of this application. The parking lot IoT system includes a variety of intelligent IoT devices to achieve the adaptation of parking space management and charging module allocation. The entrance display module is set at the entrance, which can identify vehicle information and display prompt information. Each terminal controls two corresponding parking spaces. The charging host is used to allocate charging modules and interact with the entrance display module and parking space management module.

[0084] Further, see Figure 7 , Figure 7This is a topological diagram of a unified implementation method of the parking lot IoT system in this application. The dashed lines represent communication relationships. The charging host dynamically closes the busbar switch to assign the charging module to the corresponding terminal based on vehicle demand or resource utilization within the ring-shaped charging module. The charging host can also communicate with the intelligent IoT device in the entrance display module to guide the charging vehicle to its designated location. The terminal includes a camera and a control unit. The control unit interacts with the vehicle's battery management system, reporting power requirements to the host and receiving power output from the host. This terminal is equipped with a camera that can identify vehicle information and, through communication with the parking space management module, control devices such as lifts or ground locks to facilitate vehicle entry and charging. The entrance display module includes a collection of intelligent IoT devices, including cameras, lifts, and indicator screens. The control unit interacts with the host, allowing the entrance display module to receive vehicle information mapped by the charging host and display it to the driver in real time to guide the vehicle owner to the designated location. The parking space management module includes IoT devices such as lifts or ground locks that restrict access, which are opened and closed in real time based on the parking space information assigned by the host and the license plate information identified by the terminal camera.

[0085] It's understandable that by using smart IoT devices to guide new energy vehicles to optimal parking spaces for charging, this minimizes the situation where the ring path in the ring distribution architecture is interrupted and there are no resources left, thereby reducing costs and improving operational efficiency. The cost of the entire parking lot IoT system, in addition to the ring charging module, also includes some costs for smart IoT devices. However, the involvement of smart IoT devices can, to a certain extent, solve more practical application problems, such as vehicle parking lot occupancy and parking lot congestion, making parking lots more intelligent and automated, and improving the cost-effectiveness of the entire parking lot IoT system.

[0086] S205: In response to the vehicle being connected to the charging plug corresponding to the target module and obtaining the required power of the vehicle, determine the charging power of the vehicle based on the required power and the power that can be allocated by at least part of the charging module.

[0087] Specifically, when the vehicle is connected to the charging gun corresponding to the target module and obtains the required power of the vehicle, at least the output power of the target module is provided to the charging gun. Based on the required power and the power that can be allocated to at least part of the charging module, a decision is made on whether to deploy other charging modules, thereby determining the charging power of the vehicle.

[0088] It should be noted that switches are provided between adjacent charging modules in the ring charging module. Figure 5 For example, when 2 guns call modules 1 to 3, switches 1 and 2 need to be closed. Similarly, when 11 guns call modules 11 to 12, switch 11 needs to be closed.

[0089] In one embodiment, the charging power of the vehicle is determined based on the required power and the power that can be allocated to at least part of the charging module, including: in response to the target module being in the idle partition, maintaining the current state of the switch; in response to the target module being in the working partition, controlling the switch corresponding to the target module to release the target module, obtaining the idle partition corresponding to the target module and updating the working partition in the ring charging module; obtaining the total idle power in the idle partition corresponding to the target module, and the idle power in the working partitions on both sides of the idle partition, and based on the required power, the total idle power in the idle partition and the idle power in the working partitions on both sides of the idle partition, determining the charging power of the vehicle and controlling the corresponding switches to achieve the charging power.

[0090] Specifically, the partition type of the target module is determined. When the target module is in the idle partition, the switch state in the ring charging module is temporarily not adjusted. When the target module is in the working partition, the switch that can release the target module from the working partition is controlled to be disconnected, thereby releasing the target module. At this time, the released target modules constitute the idle partition alone, thereby updating the working partition in the entire ring charging module.

[0091] Furthermore, the total idle power in the idle partition corresponding to the target module and the idle power in the working partitions on both sides of the idle partition are obtained. Based on the vehicle's required power, the total idle power in the idle partition and the idle power in the working partitions on both sides of the idle partition, the optimal charging power is set for the vehicle to be charged, thereby controlling the corresponding switches so that the vehicle is charged according to the charging power, thereby improving the power utilization rate in the ring charging module.

[0092] It is understandable that when the charging gun corresponding to the target module is connected to the vehicle, the charging gun must at least occupy the target module. When the target module is in the idle partition, the target module can be at least allocated to the charging gun without adjusting the switch. When the target module is in the working partition, the target module is released, thereby creating an idle partition corresponding to the target module in the ring charging module. After the charging gun is connected, based on the required power, the total idle power of the idle partition, and the idle power in the working partitions on both sides of the idle partition, the allocation of other charging modules other than the target module in the ring charging module is analyzed. If the power utilized by releasing other charging modules to the current charging gun is greater than the original allocation method, the other charging modules are released and allocated to the current charging gun and the charging power is determined. Otherwise, only the target module is allocated to the current charging gun and the charging power is determined, thereby improving the power utilization rate in the ring charging module.

[0093] In some implementation scenarios, the charging module corresponds to an output power. Based on the required power, the total idle power in the idle partition and the idle power in the working partitions on both sides, the charging power of the vehicle is determined and the corresponding switches are controlled to achieve the charging power, including: judging whether the idle total power meets the required power; if so, the required power is used as the charging power of the vehicle, and the switch corresponding to the corresponding charging module is closed; if not, the required power is obtained compared with the idle total power to be supplemented, and based on the output power and the idle power in the working partitions on both sides, the occupied power corresponding to the charging modules at the edges of the working partitions on both sides is determined, and it is judged whether the two groups of occupied powers are both greater than the power to be supplemented; if greater, the idle total power is used as the charging power of the vehicle, and the switch corresponding to the corresponding charging module is closed; otherwise, at least the charging module with the smallest occupied power is released, and the charging power of the vehicle is determined based on the idle total power and the output power corresponding to the released charging module, and the switch corresponding to the corresponding charging module is closed.

[0094] Specifically, the system determines whether the total idle power meets the required power. If so, the required power is used as the vehicle's charging power, and the corresponding charging module is allocated from the idle partition to the charging gun for use, closing the switch corresponding to the corresponding charging module. If the target module can meet the required power, only the target module is allocated to the current charging gun. If the target module cannot meet the required power, the target module and at least one of its adjacent charging modules are allocated from the idle partition to the current charging gun to achieve the required power, allowing the charging gun to charge quickly according to the required power.

[0095] Furthermore, if the total idle power cannot meet the required power, the difference between the required power and the total idle power is calculated as the required power. The idle power within the working zone is then subtracted from the sum of the available output powers of all charging modules within the working zone to determine the occupied power corresponding to the charging modules at the edges of the working zones on both sides. The system then determines whether both occupied power groups are greater than the required power. If so, this indicates that the allocation method for releasing charging modules within the working zone is inferior to the original allocation method. Therefore, the total idle power is used as the vehicle's charging power, and the switches corresponding to the corresponding charging modules are closed.

[0096] It is understandable that if at least one group of occupied power is less than or equal to the power to be supplemented, at least the charging module with the smallest occupied power will be released. After releasing the charging module with the smallest occupied power, it can be determined whether the charging modules that can be deployed by the charging gun can meet the required power. If it cannot be met, the updated power to be supplemented can be further determined. Based on the same comparison logic, it can be determined whether to release the charging module in another working partition. Therefore, based on the idle total power and the output power corresponding to the released charging module, the charging power of the vehicle can be determined, and the switches corresponding to the corresponding charging modules can be closed. If the idle total power and the output power corresponding to the released charging module can meet the required power, the required power will be used as the charging power. If the idle total power and the output power corresponding to the released charging module cannot meet the required power, the sum of the idle total power and the output power corresponding to the released charging module will be used as the charging power, thereby maximizing the charging power.

[0097] It should be noted that when there is an idle partition in the ring charging module and the number of charging modules in the idle partition is greater than the quantity threshold, the target module is selected according to the first quantity interval, which provides a basis for releasing the charging module from the working partition when the subsequent charging modules are occupied. By releasing one charging module in each group, more working partitions with at least two charging modules for power supply can be created, which increases the possibility of this combination and maximizes the use of the power that the ring charging module can provide.
