Detailed Implementation

[0012] To enable those skilled in the art to better understand the technical solutions of this application, the power distribution method and related apparatus provided in this application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0013] The terms "first," "second," and "third" used in this application are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first," "second," or "third" may explicitly or implicitly include at least one of that feature. In the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0014] In this document, the term "implementation" means that a specific feature, structure, or characteristic described in connection with an implementation may be included in at least one implementation of this application. The appearance of this phrase in various places in the specification does not necessarily refer to the same implementation, nor is it a separate or alternative implementation mutually exclusive with other implementations. It will be explicitly and implicitly understood by those skilled in the art that, without conflict, the implementations described herein may be combined with other implementations.

[0015] In the related technologies of a split-type 12-gun system, such as Figure 1 As shown, for a full matrix topology, each gun requires 24 bus switches (including positive and negative), and 12 guns would require 288 bus switches. The large number of bus switches results in extremely high costs, making it difficult for the market to accept. However, the allocation logic is independent of each other, and the architecture is perfect with no shortcomings.

[0016] In another related technology of star-ring architecture, such as Figure 2As shown, the number of bus couplers is significantly reduced; 12 guns require a total of 36 bus coupler switches (including positive and negative), greatly controlling costs. However, ring-type distribution has inherent logical flaws; its switching is easily affected by interference from other guns, and it suffers from the significant defect of being unable to switch if a module is missing or has no path. Furthermore, the larger the ring, the more pronounced these flaws become, limiting its applicability and resulting in low profitability for operating sites. For example... Figure 3 As shown, a simple example of a 6-gun circuit can illustrate the defects of the ring circuit: When guns 2 and 3 are in use, modules 4, 5, and 6 are idle. At this time, if gun 1 has a charging requirement and the power is relatively high, because guns 2 and 3 are in use, the bus couplers K1 and K6 cannot be used. At this time, the ring circuit is interrupted, resulting in a waste of resources. The larger the ring, the greater the probability of this interruption, and the more obvious the defect becomes.

[0017] Based on this, this application proposes a power distribution system comprising multiple basic units, each basic unit including at least three charging guns. All charging guns in each basic unit are connected in pairs via bus tie switches, and each charging gun is directly connected to a charging module group. Thus, each charging gun can be allocated to any charging module within its basic unit via the bus tie switch. Furthermore, the charging guns in the same sequence across multiple basic units are electrically connected via bus tie switch groups, allowing each charging gun to be allocated to charging module groups in other basic units via the bus tie switch within its basic unit and the bus tie switch groups between basic units, thereby improving power distribution efficiency. Compared to the aforementioned related technologies, the power distribution system of this application significantly reduces the number of bus tie switches while improving power distribution efficiency, thus ensuring resource allocation efficiency and greatly reducing costs.

[0018] For power distribution systems, charging modules can be grouped first, and then each group of charging modules can be directly connected to a corresponding charging gun. This means the charging module group is directly connected to its corresponding charging gun without being controlled by a bus tie switch; the relationship between the charging module group and its corresponding charging gun is a physical structural binding. Because the charging gun and its corresponding charging module group are directly connected, the power allocation priority for a charging module group corresponding to a charging gun is higher than that for charging guns not corresponding to it. Therefore, if a charging module group is already occupied by its corresponding charging gun, it will not be released, meaning it will not be used to provide power to other charging guns (those not corresponding to this group). Furthermore, if a charging module group is already occupied by a charging gun not corresponding to it, and that corresponding charging gun requests charging, the charging module group will be released and set to provide power to its corresponding charging gun.

[0019] The grouping granularity of the charging modules can be set according to the actual situation and is not limited here; that is, the grouping granularity can be large or small.

[0020] As mentioned above, all the charging guns in each basic unit are connected in pairs via a bus tie switch.

[0021] In one implementation, such as Figure 4 As shown, each basic unit includes 4 charging guns. The 4 charging guns are connected end to end through a bus tie switch to form a three-dimensional pyramid. In this way, the 4 charging guns in each basic unit are connected in pairs through bus tie switches. Thus, the 4 charging guns in each basic unit can be allocated to the charging module group of other charging guns in the basic unit through the bus tie switch in the basic unit, so as to achieve pure and flexible distribution through the bus tie switches between the 4 charging guns.

[0022] The basic unit contains 6 sets of bus tie switches. In addition, the bus tie definitions between the guns in this unit are mapped according to a certain logic. The reason for constructing the basic unit in this way is that the essence of pure flexible distribution is to be undisturbed and to control the charging gun to be allocated to any idle module. Each charging gun in the triangular pyramid is already bound to its own charging module group, so as long as it has a direct bus tie with other charging guns, pure flexible distribution can be achieved.

[0023] In this implementation, the power distribution system can include three basic units, where the charging guns of the same sequence in the three basic units are connected in pairs via a bus tie switch. Because the charging guns of the same sequence in the three basic units are connected in pairs via bus tie switches, there is no situation where any charging gun is interfered with by other charging guns, preventing it from accessing other idle charging guns' charging module groups. Furthermore, the triangular pyramid basic unit satisfies the requirement of having no dead zones internally, and there are no dead zones between the basic units. Thus, both the basic units and the external pathways represent an optimal topology, allowing for flexible allocation within and between units. This significantly reduces the drawbacks of ring-shaped topologies and, theoretically, can be infinitely stacked, achieving purely flexible power distribution.

[0024] In one example, the three basic units' sequential charging guns are connected in series via a bus tie switch, forming a closed-loop topology. For example... Figure 5 As shown, three identical triangular pyramid basic units, with the corresponding vertices (i.e., charging guns) at the same position forming a ring in sequence. Since a triangular pyramid has 4 vertices, this can form 4 outer rings, with 3 charging guns in each outer ring. The 3 charging guns in an outer ring are connected to each other through a bus tie switch.

[0025] In another example, the sequential charging guns of the three basic units are switched to a common DC bus via a bus tie switch. For example... Figure 6As shown, three identical triangular pyramidal basic units, with their corresponding vertices (i.e., charging guns) connected to a common DC bus via a bus tie switch.

[0026] As mentioned above, the number of charging guns in the power distribution system is greater than or equal to 12, and the specific number is not limited.

[0027] In other embodiments, the number of charging guns in the power distribution system can be greater than 12. For example, if the power distribution system has 16 charging guns, and each basic unit includes 4 charging guns, the power distribution system can include four basic units. The charging guns in the same sequence of the four basic units can be connected in pairs via a bus tie switch. Alternatively, adjacent charging guns in the same sequence of the four basic units can be connected via a bus tie switch. Or, the charging guns in the same sequence of the four basic units can be switched to a common DC bus via a bus tie switch.

[0028] Therefore, regardless of the number of basic units, the charging guns of multiple basic units in the same position can be configured as a topology through the bus tie switch. The specific connection method is not restricted. In this way, each charging gun can be transferred to the charging module of other basic units through the bus tie switch in its own basic unit and the bus tie switch group between basic units to achieve pure flexible distribution.

[0029] In another implementation, such as Figure 7 As shown, each basic unit includes 3 charging guns. The 3 charging guns are connected end to end through a bus tie switch to form a triangular basic unit. In this way, the 3 charging guns in each basic unit are connected in pairs through bus tie switches. Thus, the 3 charging guns in each basic unit can be allocated to the charging module group of other charging guns in the basic unit through the bus tie switch in the basic unit, so as to achieve pure and flexible distribution through the bus tie switches between the 3 charging guns.

[0030] In this implementation, the power distribution system may include four basic units, wherein the charging guns of the four basic units in the same order are configured into a topology through a bus tie switch.

[0031] In one example, the four basic units' sequentially connected charging guns are connected in series via a bus tie switch, forming a closed-loop topology. For example... Figure 8 As shown, four identical triangular basic units, with the corresponding vertices (i.e., charging guns) at the same position forming a ring in sequence. Since each triangular basic unit has 3 vertices, this can form 3 outer rings, with 4 charging guns in each outer ring. The 4 charging guns in one outer ring are connected in series through a bus tie switch.

[0032] In another example, the sequential charging guns of the four basic units are switched to a common DC bus via a bus tie switch. For example... Figure 9As shown, four identical triangular basic units, with their corresponding vertices (i.e., charging guns) connected to a common DC bus via a bus tie switch.

[0033] As mentioned above, the number of charging guns in the power distribution system is greater than or equal to 12, and the specific number is not limited.

[0034] In other embodiments, the number of charging guns in the power distribution system can be greater than 12. For example, if the power distribution system has 15 charging guns, and each basic unit includes 3 charging guns, the power distribution system can include five basic units. The charging guns in the same sequence of the five basic units can be connected in pairs via a bus tie switch. Alternatively, adjacent charging guns in the same sequence of the five basic units can be connected via a bus tie switch. Or, the charging guns in the same sequence of the five basic units can be switched to a common DC bus via a bus tie switch.

[0035] In the actual process of the power distribution system described above, the bus tie switch can be adjusted within the basic unit and / or between multiple basic units according to the actual situation, so as to allocate the charging gun with charging needs to the idle charging module group, thereby allowing the idle charging module group to provide energy to the charging gun with charging needs.

[0036] Therefore, this application also provides a power allocation method, such as Figure 10 As shown, the power allocation method includes the following steps.

[0037] S11: In response to the power-consuming equipment initiating a new charging request through the charging gun in the power distribution system, confirm whether the resources within the basic unit to which the charging gun belongs meet the new charging request.

[0038] When an electrical device initiates a new charging request through a charging gun in a power distribution system, it can first try to allocate resources through the basic unit to which the charging gun belongs. If resource allocation cannot be completed through the basic unit to which the charging gun belongs, it can try to allocate resources to the charging gun through other basic units through the bus tie switch between the basic units.

[0039] Thus, in response to a new charging request initiated by an electrical device through a charging gun in the power distribution system, it can first be confirmed whether the resources within the basic unit to which the charging gun belongs meet the new charging request. If the resources within the basic unit to which the charging gun belongs can meet the new charging request, step S12 can be entered to allocate resources to the charging gun through the basic unit to which the charging gun belongs. If the resources within the basic unit to which the charging gun belongs cannot meet the new charging request, step S13 can be entered to attempt to allocate resources to the charging gun through other basic units via the bus tie switch between basic units.

[0040] Specifically, the availability of resources within the basic unit to which the charging gun belongs can be determined by comparing the unused power of the basic unit with the power parameter of the new charging request. If the unused power of the basic unit is greater than the power parameter of the new charging request, then the resources within the basic unit to which the charging gun belongs can be considered to meet the new charging request; otherwise, the resources within the basic unit to which the charging gun belongs can be considered to be unable to meet the new charging request.

[0041] In one implementation, in response to a power-consuming device initiating a new charging request through a charging gun in the power distribution system, it can first be confirmed whether the charging module group corresponding to the charging gun is occupied; if it is confirmed that the charging module group corresponding to the charging gun is not occupied, it is further determined whether the resources within the basic unit to which the charging gun belongs meet the new charging request; if it is confirmed that the charging module group corresponding to the charging gun is occupied, the charging module group corresponding to the charging gun with the new charging request can be released so that the charging gun with the new charging request can utilize its corresponding charging module group. After releasing the charging module group corresponding to the charging gun with the new charging request, it can be determined whether the resources within the basic unit to which the charging gun belongs meet the new charging request.

[0042] Optionally, if the resources within the basic unit to which the charging gun belongs cannot meet the new charging request, before proceeding to step S13, step S12 can be initiated first to allocate resources to the charging gun using the idle charging module groups within the basic unit to which the charging gun belongs. Specifically, before proceeding to step S13, it can be determined whether there are idle charging module groups within the basic unit to which the charging gun belongs. If there are, proceed to step S12; otherwise, proceed to step S13.

[0043] S12: Allocate resources to the charging gun through the basic unit to which the charging gun belongs.

[0044] If the charging module group corresponding to the charging gun can meet the specific parameter conditions in the new charging request, the charging gun can be directly allocated power through the charging module group corresponding to the charging gun.

[0045] If the charging module group corresponding to the charging gun cannot meet the specific parameters in the new charging request due to insufficient unused power or other reasons, the charging gun can be transferred to another charging module group in the basic unit by adjusting the bus tie switch between the charging guns. This allows the charging gun to be powered by other charging module groups in the basic unit besides the one corresponding to the charging gun. The specific parameters in the new charging request may include the power parameters required to meet the new charging request.

[0046] The idle charging module group of the basic unit can be identified, and then the bus tie switch between the charging guns in the basic unit can be adjusted to provide power to the charging gun with a new charging request by utilizing the idle charging module group of the basic unit.

[0047] S13: By coordinating the bus tie switch group between multiple basic units, other basic units are provided with power to the charging gun that has a new charging request.

[0048] Among them, the other basic units mentioned above refer to the basic units in the power distribution system other than the basic unit to which the charging gun with a new charging request belongs.

[0049] Optionally, at least one idle charging module group of other basic units can be identified; taking the idle charging module group as the target charging module group, the power flow path from the idle charging module group to the charging gun with a new charging request is determined based on the location of the idle charging module group; and the bus tie switch in at least one power flow path is adjusted to make at least one power flow path open, so that the idle charging module group corresponding to at least one power flow path can provide power to the charging gun with a new charging request using at least one power flow path.

[0050] Optionally, all power flow paths can be opened to connect the charging gun with a new charging request to all idle charging module groups, thereby enabling the charging gun with a new charging request to be powered through all idle charging module groups.

[0051] In other embodiments, at least one idle charging module group can be selected from all idle charging module groups, wherein the selected at least one idle charging module group can precisely meet the specific parameter conditions in the new charging request, so that the power flow path of the selected at least one idle charging module group is opened to open the path between the selected idle charging module group and the charging gun with the new charging request. In this way, power can be provided to the charging gun with the new charging request through the selected at least one idle charging module group, thereby ensuring resource allocation efficiency, avoiding resource waste, and when a new charging request comes in later, the remaining idle charging module group resources can also be used to provide power for the new charging request.

[0052] When selecting charging paths, the choice of which path to use for charging is highly subjective, and the energy flow path of the charging gun may be interrupted at any time. Therefore, relying on a single path is highly likely to result in interruption, while multiple paths reduce the probability of damage. To minimize the impact of subsequent new charging requests on the energy flow path of the charging gun with a new charging request, the principle of prioritizing the number of paths can be used to determine the energy flow path of at least one idle charging module group and the charging gun, i.e., maximizing the number of energy flow paths for the charging gun. Preferably, the combination of energy flow paths with the most paths is selected, and the charging module group corresponding to the selected combination of energy flow paths can precisely meet the new charging request. Furthermore, the principle of prioritizing the number of paths, followed by prioritizing high power, can be used to determine the energy flow path of at least one idle charging module group and the charging gun. Alternatively, the principle of prioritizing the number of paths and striving for balance can be used to determine the energy flow path of at least one idle charging module group and the charging gun. Here, striving for balance means that the number of idle charging module groups on different paths is approximately the same.

[0053] The step of determining the power flow path of at least one idle charging module group and charging gun based on the principle of path quantity priority may include: determining all other basic units containing idle charging module groups; sequentially traversing each of the other basic units containing idle charging module groups in a certain order, selecting an idle charging module group from the traversed other basic units, and determining the power flow path from the selected idle charging module group to the charging gun with a new charging request, until all other basic units have been traversed or all charging module groups called by the charging gun with the current new charging request can satisfy the new charging request; if all other basic units have been traversed but a new charging request exists... If none of the charging module groups called by the charging gun for the new charging request can satisfy the new charging request, then in a certain order, all other basic units containing idle charging module groups are traversed sequentially. An idle charging module group is selected from the traversed basic units, and the power flow path from the selected idle charging module group to the charging gun with the new charging request is determined. This process is repeated until all other basic units have been traversed or all the charging module groups called by the charging gun with the new charging request can satisfy the new charging request. This process is repeated until all the charging module groups called by the charging gun with the new charging request can satisfy the new charging request, or until there are no idle charging module groups available in the entire power distribution system.

[0054] The above-mentioned step of "selecting an idle charging module group from the other traversed basic units and determining the power flow path from the selected idle charging module group to the charging gun with a new charging request" can be performed as follows: First, select an idle charging module group from the other traversed basic units and attempt to determine the power flow path from the selected idle charging module group to the charging gun with a new charging request; if the power flow path from the selected idle charging module group to the charging gun with a new charging request cannot be determined, then select another idle charging module group from the currently traversed basic units and attempt to determine the power flow path from the selected idle charging module group to the charging gun with a new charging request. This process is repeated until the power flow path from the selected idle charging module group to the charging gun with a new charging request is determined, or until all idle charging module groups have been tried.

[0055] Specifically, when selecting a second or subsequent idle charging module group from one of the traversed basic units and determining the power flow path from the selected idle charging module group to the charging gun with a new charging request, it can be first determined whether the selected second or subsequent idle charging module group can be connected to the charging gun with a new charging request through the power flow path of the previously selected idle charging module group in this traversed basic unit (i.e., the charging module group in this other basic unit that has been called by the charging gun). If so, the power flow path of the charging module group in this other basic unit that has been called by the charging gun, and the connection path between the selected second or subsequent idle charging module group and the charging module group in this other basic unit that has been called by the charging gun, can be combined to form the power flow path of the selected second or subsequent idle charging module group. Of course, in other implementations, when selecting the second or subsequent idle charging module group from another basic unit being traversed, and determining the power flow path from the selected idle charging module group to the charging gun with a new charging request, it is possible not to connect the power flow path of the charging module group that has already been called by the charging gun in this other basic unit, and to retry establishing a new power flow path. That is, it is possible to ensure that the "power flow path from the selected idle charging module group to the charging gun with a new charging request" and the "power flow path of the charging module group that has already been called by the charging gun in this other basic unit" do not have the same transfer node.

[0056] In one implementation, the other basic units containing idle charging module groups can be traversed sequentially in descending order of the number of idle charging module groups contained in the other basic units. Alternatively, the other basic units containing idle charging module groups can be traversed sequentially in descending order of the number of idle charging module groups contained in the other basic units.

[0057] When determining the power flow path from each idle charging module group to the charging gun with a new charging request, the number of transit nodes (i.e., the node where the charging gun is located, which is also the transit charging module group) in the power flow path can be minimized to reduce the probability of the power flow path being interrupted.

[0058] More preferably, the step of determining the power flow path from the idle charging module group to the charging gun with a new charging request, and adjusting the bus tie switch in at least one power flow path to ensure that at least one power flow path is open, may include: determining whether there is an idle node in the basic unit where the idle charging module group is located, where at least one charging gun in the same order as the charging gun with a new charging request is located; if there is an idle node, adjusting the bus tie switch between the charging gun with a new charging request and the idle node, and adjusting the bus tie switch between the idle node and the idle charging module group to establish a power flow path between the charging gun with a new charging request and the idle charging module group; if there is no idle node, other charging gun nodes in the basic unit where the charging gun with a new charging request is located can be used to access the idle charging module group, thereby establishing a power flow path from the idle charging module group to the charging gun with a new charging request through other charging gun nodes in the basic unit where the charging gun with a new charging request is located.

[0059] Furthermore, if there is an idle node in the basic unit where the idle charging module group is located, and at least one charging gun in the same position as the charging gun with a new charging request is located, since the idle node itself is an idle charging module group, it is possible to establish an "energy flow path from the idle node to the charging gun with a new charging request" and / or an "energy flow path from the idle charging module group to the charging gun with a new charging request". That is, it is possible to choose to call only the idle node, or to call both the idle node and the idle charging module group.

[0060] The step of establishing a power flow path from an idle charging module group to the charging gun with a new charging request through other charging gun nodes in the basic unit where the charging gun with the new charging request is located may include: determining whether there are available charging guns among the other charging gun nodes in the basic unit where the charging gun with the new charging request is located; if there are available charging guns, determining whether there are idle nodes among at least one charging gun node in the basic unit where the idle charging module group is located that has the same position as the available charging gun; if there are idle nodes, adjusting the bus tie switch between the available charging gun and the idle node, adjusting the bus tie switch between the idle node and the idle charging module group, and using the route between the idle node and the charging gun with the new charging request to establish a power flow path between the charging gun with the new charging request and the idle charging module group. If there are no idle nodes among all charging gun nodes in the basic unit where the idle charging module group is located that have the same position as the available charging gun, it may not be possible to establish a power flow path from the idle charging module group to the charging gun with the new charging request through other charging gun nodes in the basic unit where the charging gun with the new charging request is located.

[0061] In the process of establishing an energy flow path from an idle charging module group to the charging gun with the new charging request through other charging gun nodes in the basic unit where the charging gun with the new charging request is located, the possibility of "establishing an energy flow path from an idle charging module group to the charging gun with the new charging request through other charging gun nodes in the basic unit where the charging gun with the new charging request is located" can be determined by steps such as judging the available charging guns and judging whether there are idle nodes in the nodes where the charging guns with the same position are located. That is, at this time, a judgment condition can be used within the software, and the allocation command will not be triggered in real time. The specific allocation will be executed after the calculation is reasonable. The judgment logic mentioned above can be to judge whether the gun has allocated modules within the basic unit. If so, the module is used as the origin as a hypothetical gun for allocation. That is, the hypothetical gun is used as the "transfer node between the idle charging module group and the charging gun with the new charging request" to confirm the energy flow path. After confirming the power flow path from the idle charging module group to the charging gun with a new charging request through the above method, the bus tie switch on the power flow path can be adjusted to make the power flow path open.

[0062] The available charging guns mentioned above refer to the charging guns corresponding to idle charging module groups, and / or the charging guns corresponding to charging module groups invoked by charging guns with new charging requests.

[0063] Determining whether there are available charging guns among the nodes of other charging guns in the basic unit where the charging gun with the new charging request is located may include: determining whether the charging gun with the new charging request has already been transferred to the charging module group of other charging guns within the basic unit; if it has been transferred to the charging module group of other charging guns within the basic unit, then the node of the charging module group of the other charging gun that has been transferred is an available node, and the other charging gun that has been transferred is an available charging gun. Then, subsequent steps such as determining whether there are idle nodes among the nodes of at least one charging gun in the same order as the available charging gun in other basic units can be performed, so as to establish an energy flow path between the charging gun with the new charging request and the idle charging module group using the available charging gun. Furthermore, determining whether there are available charging guns in the nodes of other charging guns within the basic unit containing the charging gun with the new charging request may further include: determining whether the charging module group of the charging gun with the new charging request has not been allocated to other charging guns within the basic unit; if so, determining whether all charging module groups of other charging guns are utilized by their respective corresponding charging guns; if all are utilized by their respective corresponding charging guns, then there are no available charging guns; if there are charging module groups not utilized by their corresponding charging guns, then the node containing the charging module group not utilized by its corresponding charging gun can be designated as an available node, and the charging gun directly connected to the charging module group not utilized by its corresponding charging gun can be designated as an available charging gun, thereby determining at least one charging gun in the other basic unit with the same order as the available charging gun through the available nodes. Subsequent steps, such as whether a node containing a charging gun has an idle node, determine whether it is possible to establish a power flow path between a charging gun with a new charging request and an idle charging module group using an available node. If it is possible to establish a power flow path between an available node and an idle charging module group, and the charging module group in the available node is being used by a charging gun other than its corresponding charging gun, the comparison between the module power utilization rate after the charging module group in the available node is released and the module power utilization rate before the charging module group is released determines whether to release the charging module group in the available node. If the charging module group in the available node is released, then a power flow path between the charging gun with a new charging request and the idle charging module group is established using the available node. It can be understood that since there is a one-to-one correspondence between charging guns and charging module groups, the node containing the charging gun is equivalent to the node containing the charging module group corresponding to the charging gun. In one implementation, if the module power utilization rate before the charging module group is released is greater than the module power utilization rate after the charging module group is released, then the charging module group in the available node may not be released; otherwise, the charging module group in the available node is released.

[0064] In other implementations, if the resources within the basic unit to which the charging gun belongs cannot satisfy the new charging request, it can first be determined whether there is an idle node in the node containing at least one charging gun with the same position as the charging gun with the new charging request in other basic units. If there is an idle node in the node containing at least one charging gun with the same position as the charging gun with the new charging request in other basic units, a power flow path can be established from the charging module group of the idle node to the charging gun with the new charging request, i.e., the idle node is invoked. Alternatively, if there are other idle charging module groups in the basic unit to which the idle node belongs, a power flow path can also be established from the other idle charging module groups to the charging gun with the new charging request, i.e., the idle node and other idle charging module groups are invoked. If there is no idle node in the node containing at least one charging gun with the same position as the charging gun with the new charging request in other basic units... If an idle node, or if all idle nodes in other basic units that are in the same order as the charging gun with the new charging request have been scheduled but still cannot satisfy the new charging request, it can be determined whether there are any available charging guns in other charging gun nodes in the basic unit where the charging gun with the new charging request is located. If there are available charging guns, it can be determined whether there are any idle nodes in at least one charging gun node in other basic units that are in the same order as the available charging gun. If there are any idle nodes in at least one charging gun node in other basic units that are in the same order as the available charging gun, an energy flow path can be established from the charging module group of the idle node to the charging gun with the new charging request. In addition, if there are other idle charging module groups in the basic unit where the idle node is located, an energy flow path can also be established from the other idle charging module groups to the charging gun with the new charging request.

[0065] In this implementation, which idle nodes and / or idle charging module groups are invoked can be determined based on the actual situation and are not restricted here. When invoking idle nodes and idle charging module groups, each idle node and / or each other idle charging module group can be traversed sequentially until all charging module groups invoked by the charging gun with a new charging request can satisfy the new charging request or the entire power distribution system has no available idle charging module groups.

[0066] In addition, step S13 can be performed on the premise that there are idle charging module groups in other basic units. In this way, if there are no idle charging module groups in other basic units, S13 can be omitted, that is, resources can be allocated to the charging gun only using the charging module group inside the basic unit where the charging gun with the new charging request is located.

[0067] In some implementations, to facilitate the processing of new charging requests, when a new charging request is received, if the charging module group corresponding to the charging gun with the new charging request is occupied by other charging guns, the charging module group corresponding to the charging gun with the new charging request can be released so that the charging gun with the new charging request can utilize its corresponding charging module group.

[0068] Furthermore, considering that the node where the charging gun with the new charging request is located may be a transit node in the power flow path of the charging gun occupying its corresponding charging module group, when the charging module group corresponding to the charging gun with the new charging request is released, it is also impossible to use the target charging module group of that power flow path to provide power to the charging gun occupying its corresponding charging module group. Therefore, when releasing the charging module group corresponding to the charging gun with the new charging request, the bus tie switch at the rear end of the node where the charging gun with the new charging request is located in the power flow path of the charging gun occupying its corresponding charging module group can also be disconnected. That is, the bus tie switch between the target charging module group of the power flow path of the second charging gun and the node where the first charging gun is located can be disconnected, so as to release the charging module group that the charging gun occupying its corresponding charging module group cannot use. Here, the charging gun with the new charging request can be referred to as the first charging gun, and the charging gun occupying the charging module group corresponding to the first charging gun can be referred to as the second charging gun.

[0069] To facilitate the full utilization of unusable charging module groups, the energy flow path can be recorded when the charging gun is determined and activated. This allows for subsequent determination of which bus tie switches need to be disconnected based on the recorded energy flow path information. Optionally, branches of the charging allocation paths (i.e., energy flow paths) radiating in multiple directions from the charging gun can be recorded, sorted according to the closing time of each bus tie on each branch, and the corresponding path information can be output. For example... Figure 6 Assume that gun 2 (GUN2) allocates modules 3 (K3) and 7 (K7), and also allocates modules 2 (K2), 6 (K6), and 8 (K8), denoted as path A37 and path B268. With the power flow path of each charging gun recorded, when a charging gun has a new charging request, it can be determined whether the charging module group n directly connected to charging gun n is being used. If it is, the charging gun m using the charging module group n's label recorded by the system is found, and the corresponding specific path is located. All charging module groups and their associated bus tie switches, including those within the charging module group n and those calling the charging module group n, as well as those at the back end recorded by the system, are disconnected. Other paths or those at the front end of charging module group n remain unchanged. First, charging module group n outputs power to charging gun n; the other modules that were just released can remain temporarily unaffected.

[0070] Furthermore, to further improve energy distribution efficiency, provided that both the charging gun with a new charging request (for ease of description, the charging gun with a new charging request can be referred to as the first charging gun) and the charging gun occupying the charging module group corresponding to the first charging gun (for ease of description, the charging gun occupying the charging module group corresponding to the first charging gun can be referred to as the second charging gun) have power for charging, it can be done according to... Figure 10 The power distribution method shown distributes electrical energy to determine the current power flow path of the first charging gun and the second charging gun, and provides electrical energy to the first charging gun and the second charging gun respectively using the current power flow path of the first charging gun and the second charging gun.

[0071] The allocation order of the first and second charging guns can be determined based on factors such as remaining charging power or the time when a new charging request is initiated.

[0072] In one implementation, the remaining charging power of the first charging gun and the second charging gun can be compared. The one with the larger power is allocated first, and the one with the smaller power is allocated a new path using existing resources. Thus, if the remaining charging power of the first charging gun is less than that of the second charging gun, it is first determined whether the resources within the basic unit to which the second charging gun belongs can meet the charging request of the second charging gun. If the resources within the basic unit to which the second charging gun belongs can meet the charging request, resources are allocated to the second charging gun through the basic unit to which the second charging gun belongs. If the resources within the basic unit to which the second charging gun belongs cannot meet the new charging request, the charging module groups of other basic units are coordinated through the bus tie switch group between multiple basic units to provide power to the second charging gun. The charging module group of the first charging gun cannot be allocated to provide power to the second charging gun. Conveniently, before the path reallocation of the second charging gun is performed using the above steps, the charging module group of the first charging gun can allocate power to the first charging gun. Then, using... Figure 10 The power allocation method utilizes the remaining idle resources in the power allocation system to seek allocation paths, thereby determining other power allocation paths for the first charging gun besides its charging module group. If the remaining charging power of the first charging gun is greater than the remaining charging power of the second charging gun, then... Figure 10The power allocation method utilizes the system's currently available resources to find the allocation path for the first charging gun, and then confirms whether the resources within the basic unit to which the second charging gun belongs can meet the charging request of the second charging gun. If the resources within the basic unit to which the second charging gun belongs can meet the new charging request, resources are allocated to the second charging gun through the basic unit to which the second charging gun belongs. If the resources within the basic unit to which the second charging gun belongs cannot meet the new charging request, the charging module groups of other basic units are coordinated through the bus tie switch group between multiple basic units to provide power to the second charging gun. It can be understood that since the second charging gun also has a charging request, the charging module group of the second charging gun will not be coordinated to provide power to the first charging gun when allocating a path for the first charging gun.

[0073] In another implementation, the first new charging requester is allocated a resource, and the next new charging requester seeks an allocation path by utilizing existing resources (which can be understood as the system's currently idle resources) after the former has allocated a resource.

[0074] To facilitate understanding of the power allocation method of this application, a power allocation embodiment is provided.

[0075] Example The following steps are based on a dynamic process, meaning that regardless of how many charging guns are in operation, how many modules are occupied, or how many bus connections are closed, this logic will be followed whenever a new charging gun is added. Gun n refers to any single charging gun, gun m refers to another charging gun, module group n refers to the group of charging modules physically directly connected to gun n, and module group m refers to the group of charging modules physically directly connected to gun m.

[0076] like Figure 11 and Figure 12 As shown, a power allocation embodiment specifically includes the following steps.

[0077] A. First, regardless of the charging situation, the system needs to record the branches of the charging allocation path radiating in multiple directions from the base gun, sort them according to the closing time of each bus in each branch, and output the corresponding path information. For example... Figure 6 Assume that gun 2 allocates modules 3 and 7, and modules 2, 6 and 8. This is denoted as path A37 and path B268.

[0078] B. As mentioned earlier, because gun n and module group n are bound together (a binding relationship), when a new gun n needs charging, it's necessary to check if the module group n directly connected to gun n is in use. If it is, the system uses the module group n's recorded label to find the using gun m and its corresponding path. All module groups and their corresponding parent connections within the module group n and calling module n, as well as the backend connections recorded by the system, are disconnected. Other paths or the frontend of module n remain unchanged. Module n is first used to charge gun n, while other recently released modules remain untouched.

[0079] C. Assuming both gun n and gun m have charging capabilities, the bus connection is redistributed according to the preset allocation logic. The reason is that gun m may indirectly utilize the bus connection in the outer ring through module n to allocate power to other module groups in the basic unit. While gun n has a higher priority, its charging demand is lower. As described in step B, gun m is now left with only directly connected module group m, which is unfair to gun m. Therefore, a reassignment is necessary.

[0080] D. Compare the remaining charging power of gun m and gun n. The one with the larger power is allocated first, and the one with the smaller power is allocated first. Then, the remaining idle resources are used to find an allocation path for the one with the smaller power.

[0081] E. Preset allocation logic: 1. Prioritize allocating idle module groups within this basic unit to determine if the resources within this basic unit meet the charging requirements; if they do, stop, and since the basic unit is a purely flexible structure, it can allocate resources automatically; if not, proceed to the next step. 2. Determine if there are any idle module groups in other basic units; if there are idle module groups, mark the basic unit n containing the idle charging module group as the available basic unit N; if there are no idle module groups, end this logic.

[0082] 3. Determine whether there is an idle node in the basic unit where the idle module group is located, where at least one charging gun in the same position as the preset charging gun is located; when attempting to establish an energy flow path between the idle module group and the first charging gun for the first time, the preset charging gun is the first charging gun; when attempting to allocate energy through the "circling around" logic, the preset charging gun is the currently traversed available charging gun in the basic unit where the first charging gun is located.

[0083] 4. If there are idle nodes, the allocation relationship between basic units is triggered; otherwise, proceed to step 5. The allocation principle can be priority based on the number of paths, followed by priority based on power. This is because the ring is a dynamic allocation process. Since the willingness of vehicles to charge is highly subjective, situations like those in steps A and B may occur at any time. Therefore, if relying solely on a single path extension, the connection is likely to be interrupted, while with multiple paths, the probability of damage is lower.

[0084] 5. If there are no free nodes, in order to allocate free modules as much as possible, the allocation is carried out through the logic of "going around once". The judgment logic is to determine whether the current gun (i.e. the charging gun with a new charging request) has allocated modules within the basic unit. If so, the module is taken as the origin, that is, the charging gun directly connected to the module is "the currently traversed available charging gun in the basic unit where the first charging gun is located" (i.e. the preset charging gun), and the allocation is carried out again according to steps 3 and 4; if not, proceed to step 6.

[0085] 6. Determine whether all charging module groups within the basic unit where this gun is located are being used by the corresponding charging gun. If so, end this process, indicating that there are no other paths to follow, and the allocation ends. If so, determine whether an idle module can be allocated after the charging module group is released, following steps 3 and 4. If not, end the process and the allocation ends. If so, determine the difference between the power utilization rate of the module after release and the power utilization rate of the module before release, and then decide whether to release it.

[0086] for Figure 6 In terms of the power distribution system model, one gun directly connects to 6 groups of modules, which means that a single gun can arbitrarily allocate at least 6 groups of modules. Therefore, the probability of resource waste under this model is relatively small. When extreme situations occur, we can inform the vehicle owner to charge at a designated location through the station's indicator screen, voice broadcast, etc., which is also a remedial measure.
