Description

Technical Field

[0001] This application relates to the field of charging pile technology, and more specifically, to a charging control method, device, control unit, and charging system. Background Technology

[0002] With the vigorous development of new energy electric vehicles and their supporting charging facilities, the requirements for protection logic against direct-through risks between different power interfaces are becoming increasingly stringent in order to improve the charging efficiency of group charging systems for multiple power interfaces.

[0003] In the prior art, when a group charging system charges multiple power interfaces, the control unit allocates power units according to the charging needs of multiple power interfaces. That is, the same power unit can only be allocated to one power interface, thereby controlling the output of the power unit and finally executing the closing and opening of the parallel contactor.

[0004] However, in the existing group charging system, when allocating power units according to charging demand, there may be a delay, which may lead to misjudgment by the group charging system. This may result in the same power unit being allocated to any two or more different power interfaces at the same time, which may lead to the risk of shoot-through between different power interfaces. Summary of the Invention

[0005] The purpose of this application includes, for example, providing a charging control method, device, control unit, and charging system, which can determine in a timely manner whether there is a conflict between the charging paths of the target power interface based on the control unit, and then execute the closing operation of the switch unit to be closed, so as to avoid misjudgment by the control unit in the group charging system, thereby avoiding the same power unit being simultaneously allocated to any two or more different power interfaces, thus preventing the risk of shoot-through between different power interfaces.

[0064] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0065] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0066] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0067] In the description of this application, it should be noted that if terms such as "upper," "lower," "inner," or "outer" are used to indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship in which the product of the invention is usually placed during use, they are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0068] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0069] It should be noted that, where there is no conflict, the features in the embodiments of this application can be combined with each other.

[0070] To avoid misjudgment by the control unit in a group charging system, and thus to prevent the same power unit from being simultaneously assigned to any two or more different power interfaces, thereby avoiding the risk of shoot-through between different power interfaces, this application provides a charging control method, device, control unit, and charging system.

[0071] To clearly describe the charging control method provided in the embodiments of this application, an exemplary charging system for the charging control method will be described in detail with reference to the accompanying drawings. Figure 1 This is a schematic diagram of a charging system provided in an embodiment of this application. Figure 1 As shown, the charging system 100 may include: a control unit 110, a power array 120, a switch array 130, and multiple power interfaces 140.

[0072] The power array 120 is connected to multiple power interfaces 140 via a switch array 130, so that after the switch array 130 is connected to the power array 120, power groups corresponding to the multiple power interfaces 140 are formed according to different preset power allocation strategies. The power interfaces 140, each power unit 121 in the power array 120 and each switch unit 131 in the switch array 130 are all connected to the control unit 110, so that the control unit 110 controls each power unit 121 in the power array 120 and each switch unit 131 in the switch array 130 to allocate power units 121 according to the power demand uploaded from the multiple power interfaces 140, and controls each switch unit 131 in the switch array 130 to open and close.

[0073] It should be noted that the control unit 110 is connected to multiple power interfaces 140 via power lines and a communication bus to achieve power output and data communication. The control unit 110 is also connected to the switch array 130 via a communication bus to achieve control of the switch array 130 and data communication.

[0074] The control unit 110, as the core component of the high-power charging system 100, is mainly used for the interaction of charging data, control of the charging system, power distribution, control of the switch array 130, and protection functions. Its most important function is to ensure the charging safety of the charging system 100. The control unit 110 is used to execute the charging control method.

[0075] The power array 120 consists of many AC-to-DC power conversion units, i.e., multiple power units connected in series and / or parallel. By connecting different power units in series and / or parallel, different levels of power are output to meet the charging needs of different devices (such as electric vehicles). The power array 120 can also be a unit compatible with bidirectional energy conversion to realize V2G functionality.

[0076] The switch array 130 is used to control the output of the connected power array 120, and after the switch array 130 is connected to the power array 120, it forms a power unit corresponding to the power interface 140 according to different preset power allocation strategies.

[0077] The power interface 140 is a terminal used to directly connect to the device to be charged and perform charging services.

[0078] In one possible implementation, when the charging system is powered on and starts working, the control unit 110 determines the charging needs of different devices connected to the multiple power interfaces 140, and controls the power units 121 in the power array 120 and the switch units 131 in the switch array 130 to group them according to the charging needs. Then, by controlling the opening and closing of each switch unit 131 in the control switch array 130, the power units 121 in the power array 120 are controlled to output power to the multiple power interfaces 140, thereby completing the charging work of the charging system for the devices to be charged.

[0079] It should be noted that during the use of multiple charging guns, the control unit 110 will allocate power units according to the power requirements of the device to be charged, control the power units in the power array 120 to output, and simultaneously execute the closing and opening of the corresponding switching units in the switch array 130.

[0080] The charging system provided in this application includes: a control unit, a power array, a switch array, and multiple power interfaces. The power array is connected to the multiple power interfaces through the switch array. The power interfaces, each power unit in the power array, and each switch unit in the switch array are all connected to the control unit, which is used to execute a charging control method. Therefore, the charging system provided in this application can complete the charging of the device to be charged based on data interaction between the control unit, the power array, the switch array, and the multiple power interfaces.

[0081] Furthermore, to clearly describe the charging system 100 provided in the above embodiments, this application also provides a structural schematic diagram of a control unit 110. Figure 2 This is a schematic diagram of a control unit provided in an embodiment of this application. Figure 2 As shown, the control unit 110 may include a processor 111 and a memory 112.

[0082] The memory 112 stores machine-executable instructions that can be executed by the processor 111. When the master station device 110 is running, these machine-executable instructions are executed. The processor 111 and the memory 112 communicate via a bus. The processor 111 can execute these machine-executable instructions to implement the charging control method.

[0083] The memory 112, processor 111, and bus components are electrically connected directly or indirectly to enable data transmission or interaction. For example, these components can be electrically connected to each other via one or more communication buses or signal lines. The mobile storage device includes at least one software function module that can be stored in the memory 112 as software or firmware or embedded in the operating system (OS) of the electronic device. The processor 111 is used to execute executable modules stored in the memory 112, such as software function modules and computer programs included in the charging control method of the mobile storage medium.

[0084] The memory 112 may be, but is not limited to, random access memory (RAM), read-only memory (ROM), programmable read-only memory (PROM), erasable read-only memory (EPROM), electrically erasable read-only memory (EEPROM), etc.

[0085] The charging control method provided in this application embodiment can be executed by the processor in the control unit 110 of the charging system 100. The charging control method provided in the above embodiment of this application will be explained and described in detail below with reference to the accompanying drawings. The charging control method provided in the embodiment of this application will be explained further below. Figure 3 A flowchart illustrating a charging control method provided in this application embodiment. Figure 1 .like Figure 3As shown, in a control unit applied to a charging system, the method may include:

[0086] S201. Obtain the power allocation unit corresponding to multiple power interfaces in the charging system.

[0087] In one possible implementation, since the control unit is connected to multiple power interfaces via a communication bus, the multiple power interfaces obtain the power requirements of the multiple devices to be charged according to the multiple devices to be charged connected. Then, the multiple power interfaces upload the multiple power requirements to the control unit, and the control unit allocates power units to the power array according to the multiple power requirements, thereby obtaining the allocated power units corresponding to the multiple power interfaces in the charging system.

[0088] S202. Determine the switch unit to be closed in the charging system based on the power allocation unit corresponding to multiple power interfaces.

[0089] In one possible implementation, based on the power allocation units corresponding to the multiple power interfaces obtained, it is determined whether the switch units in the switch array corresponding to the power unit need to be closed. At the same time, when it is determined whether the switch units corresponding to the power allocation units in the charging system need to be closed, it is also possible to determine which switch units corresponding to the power allocation units in the charging system need to be opened.

[0090] It should be noted that the judgment process in the above embodiments is based on the power demand of multiple devices to be charged connected to multiple power interfaces.

[0091] S203. Determine whether there is a conflict between the charging paths of the target power interface after the switch unit to be closed is assumed to be closed.

[0092] In one possible implementation, after the control unit determines that the switch unit to be closed is assumed to be closed, it iterates through the charging path corresponding to the target power interface to which the switch unit to be closed is connected to check whether there are duplicate switch units to be closed, that is, whether there is a situation where the switch units to be closed are reused among the charging paths of the target power interface, so as to ensure that there is no situation where the switch units to be closed in the charging path corresponding to a target power interface are reused, thereby ensuring that the switch unit to be closed after being assumed to be closed does not conflict among the charging paths of multiple power interfaces.

[0093] S204. If the switch unit to be closed assumes that there is no conflict between the charging paths of multiple power interfaces after closing, then control the switch unit to be closed to perform the closing operation.

[0094] In one possible implementation, if it is determined that there is no cross-conflict between the charging paths of the multiple power interfaces after the switch unit to be closed is assumed to be closed, the switch unit to be closed can be controlled to perform a closing operation. After the closing operation is performed, the target power interface corresponding to the switch unit to be closed can charge the device to be charged. This achieves accurate control of a single switch unit to be closed, avoids the risk of power interface shoot-through, and avoids the impact on the use of multiple power interfaces.

[0095] This application provides a charging control method. It acquires power allocation units corresponding to multiple power interfaces in a charging system, determines a switch unit to be closed based on these allocation units, and then assumes the switch unit to be closed is closed. It then determines whether there is a conflict between the charging paths of the target power interfaces. If there is no conflict between the charging paths of the multiple power interfaces after the switch unit is assumed closed, the switch unit is controlled to perform a closing operation. Therefore, this application avoids misjudgments by the control unit in a group charging system, thus preventing the same power unit from being simultaneously allocated to any two or more different power interfaces, which could lead to shoot-through risks between different power interfaces and affect the use of multiple power interfaces. Simultaneously, it improves the reliability and safety of the charging control method.

[0096] exist Figure 3 Based on the above, the charging control method provided in the above embodiments of this application will be explained and described in detail below with reference to the accompanying drawings. Figure 4 A flowchart illustrating a charging control method provided in this application embodiment. Figure 2 .like Figure 4 As shown, determining whether there is a conflict between the charging paths of the target power interface after the switch unit to be closed is assumed to be closed in the above method can include:

[0097] S301. Obtain the calculated charging path of multiple power interfaces after the switch unit to be closed is assumed to be closed.

[0098] In one possible implementation, after determining the switch unit to be closed, the calculated charging path of the switch unit to be closed that can be closed is calculated for the power units connected to multiple power interfaces.

[0099] S302. Based on the calculated charging paths of multiple power interfaces, determine whether there is a conflict between the charging paths of the target power interface after the switch unit to be closed is assumed to be closed.

[0100] In one possible implementation, based on the calculated charging paths of multiple power interfaces, it is determined whether the same switch unit is reused among the assumed closed switch units required for the charging paths corresponding to the target power interface, thereby determining whether there is a conflict between the charging paths of the target power interface after the assumed closed switch units are closed.

[0101] For example, Figure 5 This is a schematic diagram of the charging control structure of a charging system provided in an embodiment of this application. Figure 5 As shown, power interface A is allocated power units 121-1, 121-2, and 121-3, with corresponding closed switch units KP1 and KP2; power interface B is allocated power units 121-4 and 121-6, with corresponding closed switch unit KP4. The output of power interface A is connected to the device A to be charged in a closed state, and the output of power interface B is also connected to the device B to be charged in a closed state. The charging control method provided in this application iterates through the assumed closed states of switch units KP1 to KP4. After statistical analysis, it can form the calculated charging path for the switch units corresponding to power interfaces A and B. Since switch unit KP3 is not assumed to be closed, there is no conflict in the allocation of power units 121-1 to 121-5. It can be determined that there is no risk of interlocking between power interfaces A and B, and charging of the device A and device B can continue.

[0102] The interlock judgment logic refers to the accurate control of the control unit to interlock a single switching unit. For example, it determines whether there is a duplicate power unit number between power units 121-1 to 121-3 of power interface A and power units 121-3 to 121-5 of power interface B. Since power unit 121-3 is duplicated, it can be determined that the switching unit KP3 corresponding to power unit 121-3 cannot be closed.

[0103] It should be noted that, in the above embodiments Figure 5 The schematic connection of the power unit and the switching unit in the diagram should not be construed as a limitation of this application.

[0104] The charging control method provided in the embodiments of this application, wherein determining whether there is a conflict between the charging paths of the target power interface after the switch unit to be closed is assumed to be closed includes: obtaining the estimated charging paths of multiple power interfaces after the switch unit to be closed is assumed to be closed; and determining whether there is a conflict between the charging paths of multiple power interfaces after the switch unit to be closed is assumed to be closed based on the estimated charging paths of multiple power interfaces. Therefore, this application can, through the assumed closed switch unit, count the estimated charging paths of the switch units to be closed that can be executed to close corresponding to the power units connected to multiple power interfaces, and determine whether the assumed closed switch units required between the charging paths corresponding to the target power interface are reused. This allows for the determination of whether there is a conflict between the charging paths of the target power interface after the switch unit to be closed is assumed to be closed, thereby avoiding the simultaneous allocation of the same power unit to any two or more different power interfaces, which could lead to shoot-through risks between different power interfaces and affect the use of multiple power interfaces. Simultaneously, it improves the reliability and safety of the charging control method of the charging system.

[0105] exist Figure 3 Based on the above, the charging control method provided in the above embodiments of this application will be explained and described in detail below with reference to the accompanying drawings. Figure 6 A flowchart illustrating a charging control method provided in this application embodiment. Figure 3 .like Figure 6 As shown, determining whether there is a conflict between the charging paths of the target power interface after the switch unit to be closed is assumed to be closed in the above method can include:

[0106] S401. Determine the desired charging path for multiple power interfaces based on the power allocation units of multiple power interfaces.

[0107] In one possible implementation, power units in the power array are allocated according to the power demand of the device to be charged, resulting in allocated power units that meet the power demand of the device to be charged. Then, the desired charging path of multiple power interfaces is determined based on the expected closure of the switching unit corresponding to the allocated power unit.

[0108] S402. Based on the desired charging paths of multiple power interfaces, determine whether there is a conflict between the charging paths of the target power interface to be closed assumed by the switch unit to be closed.

[0109] In one possible implementation, based on the desired charging paths of multiple power interfaces, it is determined whether the same switch unit is reused among the assumed closed charging paths corresponding to the target power interface, and thus whether there is a conflict between the charging paths of the target power interface after the assumed closed switch unit is closed.

[0110] For example, continue to refer to the above. Figure 5 When the devices connected to power interfaces A and B change, the power array reallocates power units according to the charging power demand of the devices. The control unit also recalculates a new desired path based on the charging power demand of the devices. For example, the charging system may determine the availability of power unit 121-3 and expect switch unit KP3 to close. However, due to communication delays or faults in the charging system, misjudgments may occur. Power unit 121-3 may be assigned to power interface B, resulting in power unit 121-3 being assigned to both power interface A and power interface B. This leads to the same power unit being assigned to different power interfaces, causing a conflict in the execution of the desired path. This results in a direct connection risk between devices A and B, creating an interlocking problem. Therefore, before the expected switch unit KP3 closes, the interlocking judgment logic is executed, meaning that the closing action of switch unit KP3 can be stopped, thereby avoiding safety hazards during the charging process of the charging system.

[0111] The charging control method provided in the embodiments of this application, wherein determining whether there is a conflict between the charging paths of the target power interface after the switch unit to be closed is assumed to be closed, includes: determining the desired charging paths of multiple power interfaces based on the power allocation units of multiple power interfaces; and determining whether there is a conflict between the charging paths of the target power interface after the switch unit to be closed is assumed to be closed based on the desired charging paths of multiple power interfaces. Therefore, this application executes the switching unit corresponding to the power allocation unit according to the desired charging path, and compares the desired charging path with the calculated charging path to see if the same switching unit is reused, that is, determining whether there is a conflict between the charging paths of the target power interface after the switch unit to be closed is assumed to be closed, thereby avoiding the risk of shoot-through between different power interfaces.

Figure 7 A flowchart illustrating a charging control method provided in this application embodiment. Figure 4 .like Figure 7 As shown, the method described above, based on the calculated charging paths of multiple power interfaces and the expected charging paths of multiple power interfaces, determines whether there is a conflict between the charging paths of the multiple power interfaces assumed to be closed by the switch unit to be closed. This can include:

[0113] S501. Determine whether the calculated charging paths of multiple power interfaces and the expected charging paths of multiple power interfaces match.

[0114] In one possible implementation, it can be determined whether the calculated charging path of multiple power interfaces matches the expected charging path of multiple power interfaces by judging whether there are any duplicate switching units between the switching units used in the expected charging path of multiple power interfaces and the switching units used in the calculated charging path.

[0115] S502. If the calculated charging paths and expected charging paths of multiple power interfaces match, then it is determined that there are no conflicts between the charging paths of the target power interface to be closed in the switch unit to be closed.

[0116] In one possible implementation, if the calculated charging path and the desired charging path of multiple power interfaces match, it can be determined that there are multiple switching units that are reused between the switching unit used in the desired charging path and the switching unit used in the calculated charging path. That is, the calculated charging path and the desired charging path are the same, and it can be determined that the switching unit to be closed assumes that there is no conflict between the charging paths of multiple power interfaces.

[0117] S503. If there is a mismatch between the calculated charging path and the corresponding expected charging path of at least one power interface, it is determined that there is a conflict between the charging paths of the target power interface to be closed by the switch unit to be closed.

[0118] In one possible implementation, if there is a mismatch between the calculated charging path and the corresponding desired charging path of at least one power interface, it can be determined that there are no duplicate switching units between the switching unit used in the desired charging path and the switching unit used in the calculated charging path.

Figure 8 A flowchart illustrating a charging control method provided in this application embodiment. Figure 5 .like Figure 8 As shown, determining whether the calculated charging paths and the desired charging paths of multiple power interfaces match in the above method can include:

[0121] S601. Determine whether the calculated charging path of each power interface and the corresponding expected charging path of each power unit are the same.

[0122] In one possible implementation, the calculated charging path of each power interface is compared with the corresponding expected charging path to determine whether the calculated charging path of each power interface and the corresponding expected charging path are the same.

[0123] S602. If the calculated charging path of each power interface is the same as the power unit on the corresponding desired charging interface, then the calculated charging path of each power interface and the desired charging path of each power interface are matched.

[0124] In one possible implementation, if the calculated charging path of each power interface is the same as the power units on the corresponding desired charging interface, then the calculated charging path of each power interface is also the same as the switching units corresponding to the power units on the corresponding desired charging interface. In this case, it can be determined that the calculated charging path of each power interface matches the desired charging path of each power interface.

[0125] S603. If the calculated charging path of each power interface and the corresponding expected charging interface indicate a different power unit, then it is determined that the calculated charging path of each power interface and the expected charging path of each power interface do not match.

[0126] In one possible implementation, if the calculated charging path of each power interface and the corresponding expected charging interface indicate a different power unit, that is, the calculated charging path of each power interface and the power units on the corresponding expected charging interface are not the same, and there is a case of duplicate access of a power unit, then it can be determined that the calculated charging path of each power interface and the expected charging path of each power interface do not match.

[0127] For example, if a power unit grouping conflict occurs, that is, if the calculated charging path of each power interface and the corresponding expected charging interface indicate a different power unit, it is determined that the switch unit corresponding to the different power unit is closed, which will cause a shoot-through of the power interface. Therefore, the switch unit corresponding to the different power unit needs to be opened to avoid the risk of shoot-through.

[0128] The charging control method provided in the embodiments of this application includes determining whether the calculated charging paths and expected charging paths of multiple power interfaces match. This includes: determining whether the power units on the calculated charging path and the corresponding expected charging path of each power interface are the same; if all power units on the calculated charging path and the corresponding expected charging interface are the same, then the calculated charging path and the expected charging path of each power interface are determined to match; if a different power unit is indicated on the calculated charging path and the corresponding expected charging interface, then the calculated charging path and the expected charging path of each power interface are determined to be mismatched. Therefore, this application can determine whether the calculated charging path and the expected charging path of each power interface match based on whether the power units on the calculated charging path and the corresponding expected charging path of each power interface are the same, thereby avoiding the risk of shoot-through between different power interfaces.

Figure 6 .like Figure 9 As shown, the method described above, based on the calculated charging paths of multiple power interfaces, determines whether there is a conflict between the charging paths of the multiple power interfaces after the assumed closure of the switch unit to be closed. This can include:

[0130] S701. Determine whether there are identical power units on the calculated charging paths of different power interfaces among multiple power interfaces.

[0131] In one possible implementation, when a switch unit in the switch matrix needs to be closed, the control unit assumes that the switch unit has been closed, then calculates the grouping information of the power units corresponding to each power interface, thereby obtaining the calculated charging path for different power interfaces, and then determines whether the same power unit is reused based on the calculated charging path for different power interfaces.

[0132] S702. If the same power unit exists on the push charging path of different power interfaces, it is determined that there is a conflict between the charging paths of the target power interface after the switch unit to be closed is assumed to be closed.

[0133] In one possible implementation, if the same power unit exists on the push charging path of different power interfaces, that is, if the same power unit is repeatedly connected on the push charging path, it can be determined that there is a conflict between the charging paths of the target power interface after the switch unit to be closed is assumed to be closed.

[0134] S703. If there are no identical power units on the push charging paths of different power interfaces, then it is determined that the charging paths of the target power interface do not conflict after the switch unit to be closed is assumed to be closed.

[0135] In one possible implementation, if there are no identical power units on the push charging paths of different power interfaces, that is, if there is no case of the same power unit being repeatedly connected on the push charging path, then it can be determined that there is no conflict between the charging paths of the target power interface after the switch unit to be closed is assumed to be closed.

[0136] The charging control method provided in the embodiments of this application, wherein the method determines whether there is a conflict between the charging paths of multiple power interfaces after the switch unit to be closed is assumed to be closed, based on the calculated charging paths of multiple power interfaces, including: determining whether there are identical power units on the calculated charging paths of different power interfaces; if there are identical power units on the pushed charging paths of different power interfaces, then it is determined that there is a conflict between the charging paths of multiple power interfaces after the switch unit to be closed is assumed to be closed; if there are no identical power units on the pushed charging paths of different power interfaces, then it is determined that there is no conflict between the charging paths of multiple power interfaces after the switch unit to be closed is assumed to be closed. Therefore, this application can determine whether there is a conflict between the charging paths of multiple power interfaces after the switch unit to be closed is assumed to be closed, based on whether there are identical power units on the calculated charging paths of different power interfaces, thereby avoiding the risk of shoot-through between different power interfaces.

[0137] Optionally, in one possible implementation, the above-described charging control method may further include:

[0138] If the switch unit to be closed assumes that there is a conflict between the charging paths of multiple power interfaces after closing, it controls the switch unit to be closed to perform a disconnection operation.

[0139] In one possible implementation, if there is a conflict between the charging paths of multiple power interfaces after the switch unit to be closed is assumed to be closed, that is, there is a situation where the same power unit is repeatedly connected, then the switch unit to be closed corresponding to the repeatedly connected power unit needs to be controlled to perform a disconnection operation as soon as possible to improve the safety performance of the charging system.

[0140] Optionally, in one possible implementation embodiment, before determining whether there is a conflict between the charging paths of the multiple power interfaces after the switch unit to be closed is assumed to be closed, the method may further include:

[0141] Obtain the status parameters of multiple power interfaces.

[0142] In one possible implementation, multiple power interfaces and the device to be charged are obtained as status parameters. These status parameters can be selected according to the actual situation. For example, the status parameters can be selected as charging gun connection status, charging status, output switch KM status, fault status, idle status, standby status, charging, stopped charging, not charging, starting, etc. There is no limitation here.

[0143] Furthermore, in one possible embodiment, determining whether there is a conflict between the charging paths of multiple power interfaces after the switch unit to be closed is assumed to be closed includes:

[0144] Based on the status parameters of multiple power interfaces, determine whether there is a conflict between the charging paths of multiple power interfaces after the switch unit to be closed is assumed to be closed.

[0145] In one possible implementation, based on the state parameters of the multiple power interfaces obtained above, it is determined whether the state parameter of each power interface is the desired parameter state, and based on whether the state parameter of each power interface is the desired parameter state, it is determined whether there is a conflict between the charging paths of the multiple power interfaces after the switch unit to be closed is assumed to be closed.

[0146] The charging control method provided in the embodiments of this application further includes, before determining whether there is a conflict between the charging paths of multiple power interfaces after the switch unit to be closed is assumed to be closed, the method further includes: acquiring the state parameters of multiple power interfaces; determining whether there is a conflict between the charging paths of multiple power interfaces after the switch unit to be closed is assumed to be closed includes: determining whether there is a conflict between the charging paths of multiple power interfaces after the switch unit to be closed is assumed to be closed based on the state parameters of multiple power interfaces. Therefore, this application can determine whether there is a conflict between the charging paths of multiple power interfaces after the switch unit to be closed is assumed to be closed based on whether the state parameters of multiple power interfaces are in the desired parameter state, thereby avoiding the risk of shoot-through between different power interfaces.

[0147] Optionally, in one possible implementation, obtaining the power allocation units corresponding to multiple power interfaces in the charging system in the above method may include:

[0148] If there is a power interface among the multiple power interfaces whose charging state changes, then obtain the allocated power unit corresponding to the multiple power interfaces.

[0149] In one possible implementation, if there is a power interface among the multiple power interfaces whose charging state changes, for example, if the power interface was previously in a charging state, and the charging power demand of the device to be charged connected to the power interface gradually decreases during the charging process, then the power unit corresponding to the device to be charged needs to be adjusted according to the change in the charging power demand of the device to be charged, and then the switching unit corresponding to the power unit needs to be adjusted, thereby changing the state of the switching unit. If the current charging state of the power interface changes from a charging state to a charging end state, then the power matrix corresponding to the power interface needs to be redistributed according to the charging end state of the power interface, that is, the power allocation units corresponding to multiple power interfaces need to be obtained.

[0150] exist Figure 3 Based on the above, the charging control method provided in the above embodiments of this application will be explained and described in detail below with reference to the accompanying drawings. Figure 10 A flowchart illustrating a charging control method provided in this application embodiment. Figure 7 .like Figure 10 As shown, the above charging control method may further include:

[0151] S801. Obtain information about the target power interface and the switch unit to be closed, assuming that there is a conflict in the charging path after the switch unit is closed.

[0152] In one possible implementation, since the charging path of the switch unit to be closed is assumed to conflict after closure, it is necessary to obtain information such as the target power unit corresponding to the target power interface and the information of the switch unit to be closed corresponding to the target power unit in the case of the charging path conflict after the switch unit to be closed is assumed to conflict.

[0153] S802. Record the information of the target power interface and the information of the switch unit to be closed.

[0154] In one possible implementation, the target power unit information of the conflicting target power interface and the information of the corresponding switch unit to be closed are recorded so that subsequent staff can perform subsequent testing and adjustments based on the record.

[0155] The charging control method provided in the embodiments of this application further includes acquiring information about the target power interface and the switch unit to be closed, which are assumed to conflict with the charging path after the switch unit is closed; and recording the information about the target power interface and the switch unit to be closed. Therefore, this application records the information about the target power interface and the switch unit to be closed, which are in conflict with the charging path, so that subsequent personnel can perform subsequent testing and adjustments based on the records, thereby improving the safety of the charging system.

[0156] To facilitate understanding of the above-described charging control method, this application also provides an example of the charging control method's flow, which will be further described below with reference to the accompanying drawings. Figure 11 A flowchart illustrating a charging control method provided in this application embodiment. Figure 8 .like Figure 11 As shown in the illustration, the embodiments provided in this application provide... Figure 8 It may include:

[0157] S901, Obtain the power allocation unit corresponding to multiple power interfaces in the charging system.

[0158] Specifically, the control unit is connected to multiple power interfaces via a communication bus. Multiple devices to be charged are connected to the multiple power interfaces. The control unit obtains the required power of the multiple devices to be charged through the multiple power interfaces. The control unit allocates power units to the power array according to the multiple required power, thereby obtaining the allocated power units corresponding to the multiple power interfaces in the charging system.

[0159] S902. Determine the switch unit to be closed in the charging system based on the power allocation unit corresponding to multiple power interfaces.

[0160] Specifically, based on the power allocation units corresponding to the multiple power interfaces obtained, the system determines whether the switch units in the switch array corresponding to the power unit need to be closed. At the same time, when determining whether the switch units corresponding to the power allocation units in the charging system need to be closed, it can also determine which switch units in the power allocation units corresponding to the charging system need to be opened.

[0161] S903. Determine whether there is a conflict between the charging paths of the target power interface after the switch unit to be closed is assumed to be closed.

[0162] Specifically, after the control unit determines that the switch unit to be closed is assumed to be closed, it traverses the charging path corresponding to the target power interface connected to the switch unit to be closed to see if there are duplicate switch units to be closed, that is, whether there is a situation where the switch units to be closed are reused among the charging paths of the target power interface, so as to ensure that there is no reuse of the switch units to be closed in the charging path corresponding to a target power interface, thereby ensuring that the switch unit to be closed after being assumed to be closed does not conflict among the charging paths of multiple power interfaces.

[0163] S904. If the switch unit to be closed assumes that there is no conflict between the charging paths of multiple power interfaces after closing, then control the switch unit to be closed to perform the closing operation.

[0164] Specifically, when it is determined that there is no cross conflict between the charging paths of multiple power interfaces after the switch unit to be closed is assumed to be closed, the switch unit to be closed can be controlled to perform a closing operation. After the closing operation is performed, the target power interface corresponding to the switch unit to be closed can charge the device to be charged. This achieves accurate control of a single switch unit to be closed, avoids the risk of power interface shoot-through, and avoids the impact on the use of multiple power interfaces.

[0165] S905. If the switch unit to be closed assumes that there are conflicts between the charging paths of multiple power interfaces after closure, then obtain the information of the target power interface where the charging paths of the switch unit to be closed are conflicted after closure, as well as the information of the switch unit to be closed, and record it.

[0166] Specifically, since there is a conflict in the charging path after the switch unit to be closed is assumed to be closed, it is necessary to obtain information such as the target power unit corresponding to the target power interface in the case of the conflict in the charging path after the switch unit to be closed is assumed to be closed, as well as the information of the switch unit to be closed corresponding to the target power unit. The obtained target power unit information of the conflicting target power interface and the information of the switch unit to be closed corresponding to the target power unit should be recorded so that the staff can perform subsequent testing and adjustment based on the record.

[0167] The charging control method provided in the embodiments of this application obtains the power allocation units corresponding to multiple power interfaces in the charging system, determines the switch unit to be closed in the charging system based on the power allocation units corresponding to the multiple power interfaces, and determines whether there is a conflict between the charging paths of the target power interfaces after the switch unit to be closed is assumed to be closed. If there is no conflict between the charging paths of the multiple power interfaces after the switch unit to be closed is assumed to be closed, the switch unit to be closed is controlled to perform a closing operation. If there is a conflict between the charging paths of the multiple power interfaces after the switch unit to be closed is assumed to be closed, the information of the target power interface with the conflicting charging paths after the switch unit to be closed is obtained and recorded. Therefore, this application can calculate the charging path of the power unit connected to multiple power interfaces by assuming a closed switch unit to be closed, and determine whether the same switch unit is reused among the required assuming closed switch units for the charging path of the target power interface. This allows for the determination of whether there is a conflict between the charging paths of the target power interface after the switch unit is assumed to be closed. This avoids the same power unit being assigned to any two or more different power interfaces at the same time, which could lead to shoot-through risk between different power interfaces and affect the use of multiple power interfaces. At the same time, it improves the reliability and safety of the charging control method of the charging system.
