[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0031] The power scheduling method provided in this application can be applied in Figure 1 The computer device may be, but is not limited to, various personal computers, laptops, smart phones, tablet computers, and various embedded devices.
[0032] In one embodiment, if Figure 2 As shown, a power scheduling method is provided, which is applied in Figure 1The client in the example is used to illustrate, including the following steps S101 to S105:
[0033] S101. Obtain a first number of charging interface devices and a second number of power module groups, and obtain a connection relationship set in which the charging interface devices are connected to the power module groups via relays.
[0034] The power module group includes at least one power module. The connection relationship between the charging interface device, the relay, the power module group and the power module is as follows: Figure 4 or Figure 7 As shown, each of the charging interface devices is connected to at least one of the power module groups via at least one of the relays, and each of the power module groups includes at least one of the power modules. Figure 4 The diagram shows an application scenario where each charging interface device is connected to the power module group via a relay. Figure 7 The illustration shows an application scenario where some charging interface devices are not connected to the power module group through relays. It should be noted that Figure 4 and Figure 7 The number of power modules given in the figure is only for reference. In actual application scenarios, the number can be increased or decreased according to actual needs. Figure 4 and Figure 7 The number of charging interface devices, relays, and power module groups is only for illustration purposes, and can be increased or decreased in actual application scenarios according to actual needs. Existing charging station equipment can also be modified using the power scheduling method of this application, which can efficiently increase or decrease the number of charging interface devices and the number of charging pile devices to meet the ever-changing charging power requirements.
[0035] S102: Generate a first relationship table between the charging interface device and the power module group according to the first quantity, the second quantity and the connection relationship set.
[0036] Specifically, first, each of the charging interface devices in the first quantity is used as each row variable of the first relationship table. Then, each of the power module groups in the second quantity is used as each column variable of the first relationship table. Finally, the connection relationship set is traversed, and the unique charging interface device and the unique power module group contained in each traversed single connection relationship are matched with the target charging interface device represented by the row variable and the target power module group represented by the column variable in the first relationship table, and the matched single connection relationship is filled into the corresponding cell in the first relationship table. Figure 5 and Figure 7are different first relationship tables corresponding to the charging interface device, the relay and the power module group in application scenarios with different connection relationships, Figure 5 The schematic table is Figure 4 The first relationship table corresponding to the schematic diagram, Figure 8 The schematic table is Figure 7 The first relationship table corresponding to the schematic diagram. It should be noted that Figure 7 In the application scenario of the connection relationship between the charging interface device, the relay and the power module group given in the schematic diagram, not every charging interface device is connected to each power module group through a relay, so there is a "—" symbol in the table, and the "—" symbol indicates that the charging interface device and the power module group are not connected through a relay.
[0037] Furthermore, there is a one-to-one correspondence between the relay and each connection relationship in the connection relationship set, the number of the relays is a third number, and after taking each of the power module groups in the second number as each column variable of the first relationship table, it also includes: comparing the size relationship between the third number and a fourth number of elements in the connection relationship set; if the third number is greater than the fourth number, reacquiring the connection relationship set, or removing the relay that is not simultaneously connected to the charging interface device and the power module group; if the third number is less than the fourth number, removing the repeated connection relationships in the connection relationship set, or reacquiring the third number of the relays.
[0038] S103: Generate a power scheduling path table corresponding to each expected power according to the first relationship table and a preset priority rule.
[0039] Specifically, first, the charging interface device is obtained as the first column of the power scheduling path table. Then, each power module group connected to each charging interface device in the first column is obtained as the second column of the power scheduling path table. At the same time, for the case where the corresponding charging interface device in the first column is the same as that in the second column, a merge cell operation is performed on the first column where the same charging interface device exists. A scheduling path parameter is generated according to the connection relationship between each charging interface device in the first column and each power module group in the second column, and the scheduling path parameter is used as the third column of the power scheduling path table. The scheduling path parameter includes priority parameter information, and the priority parameter information is set according to the preset priority rule. Figure 6 is based on Figure 5 The schematic first relationship table and a power scheduling path table generated by the priority rule, Fig. 9 is based on Figure 8The first relationship table and another power scheduling path table generated by the priority rule are shown. Figure 6 and Fig. 9 The scheduling path parameter in is a 4-digit string, the first and second digits of the string together represent the priority of the scheduling path, where "01" represents the highest priority, and "02" represents a priority lower than "01", and the third and fourth digits of the string represent the unique identifier of the relay. In the present application, the unique identifier of the relay is represented by connecting the serial number of the charging interface device connected to the relay and the serial number of the charging module group in series, which is only a preferred implementation method, and other implementation methods can also be used in actual application. By analogy, the aforementioned priority representation method is only a schematic representation of a preferred implementation method, and other implementation methods that can distinguish priorities can also be used in actual application. It should be noted that the content and length of the string of the scheduling path parameter are not limited to the schematic content in this embodiment, and the content and length of the string can be modified as needed in actual application scenarios.
[0040] Optionally, the maximum output power of each charging module group is obtained. Since the scheduling path represented by each row in the power scheduling path table only contains one charging module group, the maximum output power of each charging module group is used as the maximum output path that can be provided by the scheduling path represented by each row in the power scheduling path table, and the maximum output path is used as the fourth column of the power scheduling path table.
[0041] S104: Obtain required power of an external device connected to the charging interface device, and obtain a first power scheduling path whose expected power matches the required power from the power scheduling path table.
[0042] Specifically, first, the required power of the external device connected to the target charging interface device is obtained, and then, according to the power scheduling path table, each associated power module group connected to the target charging interface device is obtained and added to a preset set of candidate power module groups. Then, at least one of the associated power module groups is selected from the candidate power module group set and added to the charging power module group set, and the sum of the maximum powers of the associated power module groups in the charging power module group set is greater than or equal to the required power. Then, the charging power module group set is traversed, and the scheduling path parameters of each traversed associated power module group are searched according to the power scheduling path table. Finally, at least one of the scheduling path parameters is combined to generate the first power scheduling path.
[0043] Preferably, before acquiring each associated power module group connected to the target charging interface device and adding them to a preset set of selectable power module groups, first acquire a power module group in use and a power module group in a faulty state, mark the power module group in use and the power module group in the faulty state as unselectable in the power scheduling path table, and select at least one power module group from the remaining selectable power module groups in the power scheduling path table to meet the power requirements of the external device.
[0044] Furthermore, the method of acquiring each associated power module group connected to the target charging interface device and adding the associated power module group to a preset set of candidate power module groups according to the power scheduling path table also includes: traversing the set of candidate power module groups to check whether the traversed power module group has a fault, and if so, removing the traversed power module group; traversing the set of candidate power module groups to check whether the traversed power module group is working, and if so, removing the traversed power module group.
[0045] Further, the selecting at least one of the associated power module groups from the set of candidate power module groups to be added to the charging power module group set, wherein the sum of the maximum powers of the associated power module groups in the charging power module group set is greater than or equal to the required power, comprises: first, sorting the associated power module groups according to the priority parameter information; and then, selecting the associated power module groups in order from high to low priority to add them to the charging power module group set until the sum of the maximum powers of the associated power module groups in the charging power module group set is greater than the required power.
[0046] S105. According to the first power scheduling path, obtain a corresponding charging interface device, relay, and power module group to charge the external device.
[0047] The connection relationship between the charging interface device, the relay and the charging module group is established to establish a connection relationship table, and then the connection relationship table is combined with the pre-set priority rules to generate a power scheduling path table corresponding to each expected power. The power path table can meet the power supply requirements of various expected powers. When the charging interface device receives a charging power requirement, an optimal power scheduling path is searched in the power scheduling path table by looking up the table, and finally the corresponding charging module group is operated according to the optimal power scheduling path to provide the expected power to the outside through the relay and the charging interface device. This application abstracts all charging and discharging power storage devices into power module groups, and only focuses on the maximum output power of each power module group and the connection method of each power module group with the charging interface device. It can unify many power scheduling methods, solve the problem of chaotic version management of power scheduling methods, and avoid safety accidents caused by incorrect use of power scheduling methods in actual applications. At the same time, the power scheduling method of this application can efficiently realize the increase or decrease in the number of charging interface devices and the increase or decrease in the number of charging pile devices to meet the ever-changing charging power requirements. For example, the charging piles at urban charging stations provide pure electric vehicle charging services with different power requirements through charging guns, but the total power requirements of the batteries used by various pure electric vehicles are not necessarily the same. The method of this embodiment can efficiently meet various different charging power requirements.
[0048] It should be understood that the order of execution of the steps in the above embodiment does not necessarily mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiment of the present invention.
