[0056] The present application provides a power scheduling method, device and storage medium for a charging stack, which are described in detail below. It should be noted that the description order of the following embodiments does not limit the preferred order of the embodiments of the present application. In the following embodiments, the description of each embodiment has its own emphasis. For parts that are not described in detail in a certain embodiment, please refer to the relevant description of other embodiments.

[0057] At present, in order to adapt to the fast charging of charging pile charging technology, the power requirements for charging piles are getting higher and higher. When the voltage, current and power of charging piles are getting larger and larger, the form of charging piles is also developing from single charging piles to high-power charging piles. The charging pile includes multiple charging modules, each of which can perform charging operations independently. However, due to the uneven distribution of charging demand or unreasonable allocation of charging modules, some charging modules may be idle and unable to fully exert their charging capacity, which in turn leads to a decrease in the charging efficiency of the charging pile. In addition, if the charging power allocation mechanism cannot be allocated based on power demand, when the power allocation of some charging ports in the charging pile is too high, it will cause the power allocation of other charging ports to be lower, which will cause power waste, so that some charging modules may not be able to fully exert their charging capacity, resulting in a decrease in charging efficiency, which will extend the charging time of some charging ports, further restricting the improvement of charging efficiency and affecting energy utilization efficiency.

[0058] In view of this, the present application provides a power scheduling method for a charging stack, which reasonably allocates idle charging modules in the charging stack to the charging ports with the largest power demand in the charging terminal group, so that the charging capacity of the charging modules can be fully utilized, avoiding the idleness of the charging modules and improving the charging efficiency of the charging stack.

[0059] See also Figure 1 and Figure 2 , Figure 1 A schematic diagram of a flow chart of a power scheduling method for a charging stack provided in an embodiment of the present application, Figure 2 A schematic diagram of the structure of a charging stack provided in an embodiment of the present application. The present application provides a power scheduling method for a charging stack, wherein the charging stack includes multiple charging modules and multiple charging ports, and the multiple charging modules and the multiple charging ports are connected to form a topological structure; wherein the topological structure formed by the connection of the multiple charging modules and the multiple charging ports enables any charging module to be called by any charging port. Exemplarily, the charging stack includes a charging module and 12 charging ports, and the charging module includes 12 charging modules, and the 12 charging modules and the 12 charging ports are connected to form a topological structure, so that charging modules 1 to 12 can be called by any charging port from charging port 1 to charging port 12, and the charging port can be used to connect a charging gun so that the charging module supplies power to the charging gun through the charging port, and the charging module is used to provide charging power to the charging port after being called by the charging port.

[0060] In some embodiments, the method comprises:

[0061] The current required power of each charging port and the current total power currently allocated to each charging port are obtained.

[0062] It should be noted that the current required power of the charging port can be calculated based on the current required current and voltage of the charging port; the current total power currently allocated to each charging port refers to the sum of the powers of all charging modules currently allocated to the charging port.

[0063] If the current required power of the charging port and the current total power do not meet the preset power redundancy condition, the charging port is determined as a charging port group.

[0064] In some embodiments, the preset power redundancy condition includes: the difference between the total power of the charging port and the required power is not greater than the preset power threshold. Wherein, the preset power threshold is the sum of the redundant power of each charging module, that is, the sum of the redundant power of all charging modules currently assigned to the charging port. The redundant power is the additional power capacity reserved to cope with emergencies or future expansion needs, and thus the preset power thresholds corresponding to different charging ports may be different; in some embodiments, the redundant power of a charging module in this application may be 5KW, and the setting of the redundant power may be set based on the actual design requirements of the scheme, which is not limited in this application. Exemplarily, all charging modules currently assigned to charging port 1 include charging module 1, charging module 2, and charging module 3, and the total number of charging modules currently assigned to charging port 1 is 3, and the preset power redundancy condition corresponding to the current charging port 1 is that the difference between the total power of charging port 1 and the required power is not greater than 15KW.

[0065] Determine the current power requirement of each charging port in the charging terminal group based on the current required power of each charging port and the current total power;

[0066] When there is an idle charging module among the multiple charging modules that has not been called by the charging port, the idle charging module is allocated to the charging port with the largest current power demand in the charging end group.

[0067] In some embodiments, the idle charging module is assigned to the charging port with the largest current power demand in the charging end group. This can be done by assigning one idle charging module to the charging port with the largest current power demand in the charging end group at a time, then updating the charging end group and the power demand of the charging end group, and then assigning the idle charging module to the charging port with the largest power demand in the updated charging end group. It can also be done by assigning multiple idle charging modules to the charging port with the largest current power demand in the charging end group at a time, then updating the charging end group and the power demand of the charging end group, and then assigning the idle charging module to the charging port with the largest power demand in the updated charging end group.

[0068] It should be noted that when the charging port is supplying power, the power demand of the charging port will change during the charging process, and thus the power scheduling method of the charging stack needs to be executed in real time or based on a preset time interval until the charging port completes charging. In addition, when there are multiple charging ports with the largest current power demand in the charging terminal group, the idle charging module is assigned to any one of the charging ports with the largest current power demand in the charging terminal group. In some embodiments, based on the number of the charging port, the idle charging module can be assigned to the charging port with the smallest number among the charging ports with the largest current power demand in the charging terminal group; in other embodiments, the idle charging module can be assigned to the charging port in the charging terminal group that is closest to the idle charging module. The charging module is called by the charging port, which means that the charging module is assigned to the charging port, that is, the charging power of the charging module is assigned to the charging port.

[0069] In some embodiments, the power of the multiple charging modules is 40KW. It should be noted that the charging power of the multiple charging modules can be the same or different, which is specifically set based on the actual solution requirements and is not limited in this application.

[0070] Through the above technical solution, if the current required power of the charging port and the current total power do not meet the preset power redundancy condition, the charging port is determined as a charging terminal group, that is, the charging port that needs to increase power is selected; through the current power demand of each charging port in the charging terminal group, when there is an idle charging module that is not called by the charging port in multiple charging modules, the idle charging module is allocated to the charging port with the largest current power demand in the charging terminal group, that is, the idle charging module is preferentially allocated to the charging port with the largest current power demand in the charging terminal group. By preferentially allocating to the charging port with the largest current power demand, the charging modules can be allocated more evenly, the overall utilization rate of the charging stack can be improved, and at the same time, it helps to reduce energy waste and reduce the operating cost of the charging stack. In addition, in the present application, the preset power redundancy condition is used as a criterion to determine the charging terminal group, which can ensure that the charging stack can maintain stable operation under any circumstances. Even if the power demand of a charging port suddenly increases, the charging stack still has enough redundant power to meet the demand, avoiding overload or failure to meet the charging demand, making the charging stack more flexible and adaptable.

[0071] In some embodiments, determining the current power requirement of each charging port in the charging terminal group based on the current required power of each charging port and the current total power includes:

[0072] Determine the ratio of the current required power of each charging port to the current total power;

[0073] The ratio of the current required power to the current total power is determined as the current power requirement of the charging port.

[0074] Specifically, the ratio of the current required power to the current total power is the value of the current required power divided by the current total power. If the ratio of the current required power to the current total power of the charging port is larger, it means that the current power demand of the charging port is larger.

[0075] In some other embodiments, determining the current power requirement of each charging port in the charging terminal group based on the current required power of each charging port and the current total power includes:

[0076] Determine the difference between the current required power and the current total power of each charging port;

[0077] The difference between the current required power and the current total power is determined as the current power requirement of the charging port.

[0078] Specifically, if the difference between the current required power of the charging port and the current total power is larger, it means that the current power requirement of the charging port is larger.

[0079] Through the above technical solution, the current power demand of each charging port in the charging terminal group is determined based on the relationship between the current required power of each charging port and the current total power as a criterion, thereby determining the charging port with the largest current power demand in the charging terminal group, so that the idle charging module is preferentially called to provide charging power for the charging port, and the charging modules are more evenly distributed, thereby improving the overall utilization rate of the charging stack, while helping to reduce energy waste and reduce the operating cost of the charging stack.

[0080] See also Figure 3 , Figure 3 An example flow chart of a power scheduling method provided in an embodiment of the present application. In some embodiments, a method for obtaining the current total power currently allocated to each charging port includes:

[0081] When each charging port starts supplying power, if there is an idle charging module among the multiple charging modules, an available charging module is determined from the idle charging modules based on the initial required power of the corresponding charging port.

[0082] It should be noted that when the charging port starts power supply, it means that when the charging port is connected to a new charging gun, the charging port does not call any charging module at this time, and the current total power of the charging port is 0. Therefore, when the charging port starts power supply, a charging module needs to be allocated to the charging port, and the initial required power is the required power corresponding to the charging gun charging when the new charging gun is connected.

[0083] If there is no idle charging module among the multiple charging modules, an available charging module is determined from the called charging modules in use.

[0084] It should be noted that the available charging module belongs to at least one charging module among the called charging modules in use.

[0085] The charging power of the available charging module is determined as the current total power of the corresponding charging port.

[0086] It should be noted that the charging module in use refers to the charging module that has been called by the charging port at this time, and the idle charging module refers to the charging module that has not been called by the charging port at this time. It should be understood that when each charging port starts to supply power, it means that the charging port has completed one charging, or the charging port has not been started to supply power; if the charging port has completed one charging, all the charging modules called by the charging port are released as idle charging modules.

[0087] Through the above technical solution, when the charging port starts to supply power, an idle charging module is preferentially provided to the charging port. If there is no idle charging module, an available charging module is selected from the charging modules in use to provide charging power for the charging port. The charging demand of the charging port that starts supplying power can be quickly met, the waiting time can be reduced, the charging efficiency can be improved, and frequent calls to other charging ports can be avoided, thereby reducing the scheduling time and energy waste of the charging stack.

[0088] In some embodiments, based on the startup power supply duration of the charging port, if the startup power supply duration of the charging port does not reach the preset charging duration, it means that at the startup power supply stage of each charging port, if there is an idle charging module among the multiple charging modules, then based on the initial required power of the corresponding charging port, the available charging module is determined from the idle charging modules; if there is no idle charging module among the multiple charging modules, then the available charging module is determined from the called charging modules in use. In some embodiments, the preset charging duration can be 5 minutes, which can be designed according to actual needs.

[0089] Furthermore, in some embodiments, if the startup power supply duration of the charging port reaches the preset charging duration, the method for obtaining the current total power currently allocated to each charging port includes: for each charging port, respectively, obtaining the sum of the charging powers of all charging modules currently called by the charging port as the current total power of the charging port. Furthermore, based on obtaining the current required power of each charging port and the current total power currently allocated to each charging port; if the current required power of the charging port and the current total power do not meet the preset power redundancy condition, the charging port is determined as a charging end group; based on the current required power and the current total power of each charging port, the current power requirement of each charging port in the charging end group is determined; when there is an idle charging module that is not called by the charging port among multiple charging modules, the idle charging module is allocated to the charging port with the largest current power requirement in the charging end group.

[0090] Through the above technical solution, if the charging time of the charging port does not reach the preset charging time, an idle charging module is preferentially provided for the charging port. If there is no idle charging module, an available charging module is selected from the charging modules in use to provide charging power for the charging port. Furthermore, when the charging time of the charging port does not reach the preset charging time, it means that the initial stage of charging of the charging port can quickly meet the charging demand of the charging port that starts the power supply, thereby reducing waiting time, improving charging efficiency, avoiding frequent calls to other charging ports, and reducing the scheduling time and energy waste of the charging stack. If the charging time of the charging port reaches the preset charging time, and the preset power redundancy condition is not met between the current demand power of the charging port and the current total power, the charging port is determined as a charging terminal group, and the charging port that needs to increase power is selected; through the current power demand of each charging port in the charging terminal group, when there are idle charging modules that are not called by the charging port in multiple charging modules, the idle charging modules are allocated to the charging port with the largest current power demand in the charging terminal group, and the idle charging modules are preferentially allocated to the charging port with the largest current power demand in the charging terminal group. Then, when the charging time of the charging port reaches the preset charging time, it means that the charging port is in the middle stage of charging. By preferentially allocating to the port with the largest current power demand, the charging modules can be allocated more evenly, thereby improving the overall utilization rate of the charging stack, while helping to reduce energy waste and reduce the operating cost of the charging stack.

[0091] In some embodiments, a plurality of charging modules and a plurality of charging ports are connected one-to-one through corresponding charging lines, and based on the initial required power of the corresponding charging port, an available charging module is determined from the idle charging modules, including:

[0092] Obtaining the distance between the corresponding charging port and each idle charging module, wherein the distance between the corresponding charging port and the charging module connected through the corresponding charging line is the shortest;

[0093] Based on the order of distance from near to far, the idle charging modules are determined as available charging modules in sequence until the total charging power of all available charging modules meets the required power of the corresponding charging port;

[0094] If the total charging power of all idle charging modules does not meet the required power of the corresponding charging port, all idle charging modules are determined as available charging modules.

[0095] It should be noted that satisfying the power requirement of the corresponding charging port means that the sum of the powers of the charging modules called by the charging port is greater than or equal to the required power. In some embodiments, the current required power of the charging port is calculated based on the current required current and voltage of the charging port, and then the number of charging modules currently required by the charging port can be obtained in combination with the power provided by the charging module, that is, the required power is met. In addition, if there is a charging port that is equidistant from multiple idle charging modules, at least one charging module can be selected based on the initial required power of the corresponding charging port.

[0096] In some embodiments, multiple charging modules and multiple charging ports can be numbered based on the arrangement order, so that the distance is indicated based on the number. Specifically, multiple charging modules and multiple charging ports are connected one-to-one through corresponding charging lines, and the charging modules are numbered in sequence based on the arrangement order, and the charging modules and charging ports connected at both ends of each charging line have the same number.

[0097] Based on the initial required power of the corresponding charging port, an available charging module is determined from the idle charging modules, including:

[0098] Obtaining the absolute value of the difference between the serial number of the corresponding charging port and each idle charging module;

[0099] Based on the absolute value of the number difference, the idle charging modules are determined as available charging modules in order from small to large, until the total charging power of all available charging modules meets the required power of the corresponding charging port; wherein, the order of the absolute value of the number difference from small to large represents the order of distance from near to far.

[0100] If the total charging power of all idle charging modules does not meet the required power of the corresponding charging port, all idle charging modules are determined as available charging modules.

[0101] It should be noted that if the absolute value of the difference between the number of the corresponding charging port and each idle charging module is the same, it means that the distance from the charging port to each idle charging module with the same absolute value of the number difference is the same, and at present, at least one of the charging modules can be selected based on the initial required power of the corresponding charging port; for example, if the corresponding charging port is numbered 3, and there are idle charging modules numbered 2 and 4 at this time, then the distance from the charging port numbered 3 to the charging modules numbered 2 and 4 is equal, and thus the required power of the charging port numbered 3, if calling two charging modules still cannot meet the required power, then call the charging modules numbered 2 and 4 at the same time; if calling one charging module can meet the required power, then call any one of the charging modules numbered 2 and 4.

[0102] In some embodiments, the number of charging modules required by the charging port can be obtained based on the current power requirement of the charging port and the charging power of each charging module, so as to determine whether the idle charging modules can meet the current power requirement of the charging port. If the current power requirement of the charging port is not met, all the idle charging modules are selected and allocated to power the charging port.

[0103] It should be noted that the arrangement order of the charging modules is the arrangement order of the positions of the charging modules; the difference in numbers between the charging port and the idle charging modules is obtained, and the idle charging modules are selected in order from small to large based on the absolute value of the number difference and assigned to the charging port, that is, in order to make the charging port give priority to calling the module closest to it.

[0104] Through the above technical scheme, the number difference between the charging port and the idle charging module is obtained, and the idle charging modules are selected in order from small to large based on the number difference and allocated to the charging port, so that the charging port preferentially calls the module closest to it, thereby making the charging line the shortest, which can reduce the length of the charging line, reduce line loss, and improve charging efficiency; based on the number difference, the idle charging modules are selected in order from small to large and allocated to the charging port until the current required power of the charging port is met or all the idle charging modules are selected, so that the current required power of the charging port is met as much as possible, so that the charging port can obtain sufficient power faster, improve charging efficiency, avoid idle resources of the charging module, and improve the overall utilization of the charging stack.

[0105] In some embodiments, determining an available charging module from the called charging modules in use includes:

[0106] Determine types of multiple charging ports, where the types of the charging ports include a first charging port and a second charging port;

[0107] It should be noted that the maximum charging power provided by the first charging port is less than the maximum charging power of the second charging port; in some embodiments, the first charging port may be a fast charging port, and the second charging port may be a super charging port, wherein the maximum charging power of the fast charging port may be 250kW, and the maximum output current of the fast charging port may be 250A, and the maximum charging power of the super charging port may be 480kW, and the maximum output current of the super charging port may be 600A.

[0108] If there is a target first charging port that calls multiple charging modules at the same time, the first target charging module with the shortest calling time is determined from all the charging modules called by all the target first charging ports, and an available charging module is selected from all the charging modules called by the target first charging port that calls the first target charging module.

[0109] For example, if there are target first charging ports that call multiple charging modules at the same time, each of which calls at least two charging modules, the first target charging module represents the charging module with the shortest calling time, that is, the charging module that was last called. It should be noted that the calling time of a charging module represents the time during a calling process of the charging module. For example, if the charging module numbered 5 is called by the charging port numbered 3, and then the charging module numbered 5 is called by the charging port numbered 4, the calling time of the charging module numbered 5 is recalculated after being called by the charging port numbered 4.

[0110] If there is no target first charging port that calls multiple charging modules at the same time, the second target charging module with the shortest calling time is determined from all the charging modules called by all the second charging ports, and an available charging module is selected from all the charging modules called by the second charging port that calls the second target charging module.

[0111] Exemplarily, the second target charging module indicates the charging module with the shortest calling time, that is, the charging module that was last called. It should be noted that in this application, it is assumed that the number of charging modules called by the second charging port is multiple.

[0112] In some embodiments, an available charging module is selected from each charging module called by the target first charging port and assigned to the charging port, wherein the available charging module may be one charging module, and further, the available charging module may be the charging module closest to the charging port among the charging modules called by the first charging port. An available charging module is selected from each charging module called by the target second charging port and assigned to the charging port, wherein the available charging module may be one charging module, and further, the available charging module may be the charging module closest to the charging port among the charging modules called by the second charging port. The specific number of available charging modules selected may be selected based on the solution design, and this application does not limit this.

[0113] Through the above technical solution, an available charging module is selected from the called charging modules and assigned to the charging port, and the charging module called by the first charging port is called first, and then the charging module called by the second charging port is called, so as to avoid affecting the charging process of the second charging port as much as possible, and ensure that the second charging port can continue to charge at high power. In addition, an available charging module is selected from each charging module called by the target first charging port or the target second charging port and assigned to the charging port, on the one hand, to ensure that the charging port has a charging module to provide charging, and on the other hand, to avoid affecting the charging process of other charging ports as much as possible. In some embodiments, multiple charging modules and multiple charging ports are connected one by one through corresponding charging lines, and the method also includes:

[0114] If the current required power of the charging port and the current total power meet the preset power redundancy condition, the distance between the charging port and each charging module currently assigned to the charging port is obtained, wherein the distance between the charging port and the charging module connected through the corresponding charging line is the shortest;

[0115] The charging modules currently assigned to the charging port are released in order based on the distance from far to near, until the difference between the current total power of the charging port and the required power of the charging port meets the preset threshold.

[0116] In some embodiments, the plurality of charging modules and the plurality of charging ports may be numbered based on the arrangement order, so that the distance is indicated based on the number, the plurality of charging modules and the plurality of charging ports are connected one-to-one through corresponding charging lines, the charging modules are numbered in sequence based on the arrangement order, and the charging modules and the charging ports connected at both ends of each charging line have the same number; the method further includes:

[0117] If the current required power of the charging port and the current total power meet the preset power redundancy condition, the difference between the number of the charging port and each charging module currently assigned to the charging port is obtained, wherein the distance between the charging port and the charging module connected through the corresponding charging line is the shortest, that is, the charging port with the same number is the shortest distance to the charging module;

[0118] Based on the order of the number difference from large to small, each charging module currently assigned to the charging port is released in sequence until the difference between the current total power of the charging port and the required power of the charging port meets the preset threshold. Among them, the order of the number difference from large to small is the relationship of distance from far to near.

[0119] In some embodiments, the current required power and the current total power of the charging port meet a preset power redundancy condition, which means that the difference between the current total power of the charging port and the current required power is greater than a preset power threshold.

[0120] It should be noted that the charging modules are released as idle charging modules in descending order based on the number difference, so that the charging port preferentially releases the module with the farthest calling distance.

[0121] Through the above technical solution, the charging modules are released as idle charging modules in order from large to small based on the number difference until the current total power of the charging port meets the current required power of the charging port, so that the called charging line is the closest. This can reduce the length of the charging line, reduce line loss, improve charging efficiency, and ensure that the current total power of the charging port meets the current required power of the charging port, avoid excessive charging power, rationally use charging resources, and improve charging efficiency and resource utilization.

[0122] In some embodiments, a plurality of charging modules and a plurality of charging ports are connected one-to-one through corresponding charging lines, the charging stack further comprises a contactor module, the contactor module comprises a plurality of contactors, and the two charging lines are connected through the contactor; releasing each charging module currently assigned to the charging port comprises:

[0123] Disconnect the contactor connected between the first charging circuit and the second charging circuit to disconnect the charging modules currently assigned to the charging port from the charging port. The first charging circuit is the charging circuit connected to the charging modules currently assigned to the charging port, and the second charging circuit is the charging circuit connected to the charging port.

[0124] Exemplarily, the contactor module includes contactors K1 to K11, the first charging circuit includes a charging circuit connected to the charging module numbered 2, and the second charging circuit is a charging circuit connected to the charging port numbered 4, and then the contactors K2 and K3 are disconnected to disconnect the charging modules currently assigned to the charging port from the charging port. It should be noted that releasing the charging modules currently assigned to the charging port may be releasing the charging modules as idle charging modules, or releasing the called charging modules as available charging modules.

[0125] In some embodiments, multiple charging modules and multiple charging ports are connected one-to-one through corresponding charging lines, the charging stack further includes a contactor module, the contactor module includes multiple contactors, and the two charging lines are connected through the contactor; the idle charging module is allocated to the charging port with the largest current power demand in the charging terminal group, including:

[0126] Close the contactor connected between the third charging circuit and the fourth charging circuit to conduct the idle charging module to the charging port with the largest current power demand in the charging terminal group. The third charging circuit is the charging circuit connected to the idle charging module, and the fourth charging circuit is the charging circuit connected to the charging port with the largest current power demand in the charging terminal group.

[0127] Exemplarily, the third charging circuit is a charging circuit connected to an idle charging module numbered 2, and the fourth charging circuit is a charging circuit connected to a charging port numbered 4, and then contactors K2 and K3 are closed to connect the idle charging module to the charging port with the largest current power demand in the charging terminal group.

[0128] It should be noted that the two ends of a contactor can also be connected to two non-adjacent charging circuits. Then, the contactor connecting the two non-adjacent charging circuits can be disconnected or closed to call or release the charging module, thereby reducing the number of contactors and simplifying the control of the contactors. The present application does not limit the two charging circuits connected to the two ends of each first contactor. The two charging circuits can be two adjacent charging circuits or two non-adjacent charging circuits. Among them, the contactor is an electrical switching device, whose main function is to control the on and off of the current during the charging process. In some embodiments, multiple contactors can be numbered in sequence, and the charging module ranked first and the contactor ranked first can be set to the same number, and then the opening and closing of the contactor can be controlled based on the number.

[0129] Through the above technical solution, if the charging port calls or releases a charging module that is not connected through a charging line, the contactor between the charging line corresponding to the charging port and the charging line corresponding to the charging module is closed or disconnected, thereby achieving the effect of calling or releasing the charging module. In addition, the contactor can play a protective role in the circuit. When other components or devices in the charging stack fail or are abnormal, the contactor can quickly disconnect the circuit to avoid problems such as excessive current or circuit short circuit, thereby protecting the safety of the charging stack and related equipment.
