Technical Field

[0001] This application relates to the field of charging pile technology, and in particular to a charging pile power distribution method, system, device, equipment and storage medium. Background Technology

[0002] In recent years, the number of new energy electric vehicles has exploded, and the number of DC charging piles, which serve as their infrastructure, has also increased dramatically.

[0003] To ensure the effective utilization of DC charging piles, high-power DC charging piles with multiple charging interfaces have become the preferred solution for most operators. The mainstream products of this type adopt a matrix power distribution scheme, which requires a huge number of power switches, resulting in a waste of resources and increasing the construction cost of charging piles. Summary of the Invention

[0004] In view of this, this application provides a charging pile power distribution method, system, device, equipment and storage medium, which aims to reduce the construction cost of charging piles while ensuring normal use of charging piles.

[0005] To achieve the above objectives, this application provides a charging pile power allocation method, which includes the following steps:

[0006] Obtain the power requirements of the charging interface;

[0007] Based on the power requirements and the preset charging module power, the charging module to be used is determined; wherein, the charging module is connected to the charging interface through a preset power distribution module to form a circuit, and the power distribution module is equipped with a power switch for controlling the circuit to be turned on and off;

[0008] The power switch corresponding to the charging module to be used within the power distribution module is closed so that the charging interface outputs power that meets the power requirements.

[0009] For example, the step of determining the charging module to be used based on the power requirement and the preset charging module power includes:

[0010] Based on the power requirements and the preset charging module power, calculate the required number of charging modules;

[0011] If the required quantity is greater than the quantity of each power distribution module, then a first power circuit directly connected to the charging interface and a second power circuit not directly connected are determined from each power distribution module.

[0012] Based on the required quantity, select some charging modules from the first power circuit and a portion of the charging modules from the second power circuit as the charging modules to be used.

[0013] For example, the step of selecting a portion of the charging modules in the first power circuit and a portion of the charging modules in the second power circuit as the charging modules to be used based on the required quantity includes:

[0014] Based on the required quantity, the charging modules in the first power circuit are selected in ascending order of their preset numbers, and some charging modules in the second power circuit are selected in descending order of their preset numbers.

[0015] The selected charging module will be used as the charging module to be used.

[0016] For example, the step of selecting a portion of the charging modules in the second power circuit in descending order of the preset numbers includes:

[0017] According to the preset number, select the charging module in all the second power circuits corresponding to the power distribution module with the largest number;

[0018] If the number of charging modules does not meet the required number, then the charging modules in the second power circuit corresponding to the remaining power distribution modules are selected in descending order of the preset numbers until the number of charging modules meets the required number.

[0019] For example, the step of determining the charging modules to be used based on the required quantity includes:

[0020] If the required quantity is not greater than the quantity of each power distribution module, then a first power circuit directly connected to the charging interface is determined from each power distribution module.

[0021] Based on the required quantity, a portion of the charging modules in the first power circuit are selected as the charging modules to be used.

[0022] For example, after the step of controlling the power switch within the power distribution module corresponding to the charging module to be used to close, the method includes:

[0023] When the charging interface is detected to be no longer in use, the charging modules corresponding to the charging interface are released sequentially in the reverse order of when the charging module was selected.

[0024] For example, to achieve the above objectives, this application also provides a charging pile power distribution system, which includes a charging module, a power distribution module, and a charging interface:

[0025] The charging module is used to provide corresponding electrical energy. When the charging module is connected to the charging interface, the charging module acts as a module that outputs electrical energy.

[0026] The charging interface is used to receive electrical energy output by the charging module and output it to the outside.

[0027] The power distribution module is used to control the connection and disconnection of the power switch in the circuit formed by the charging module and the charging interface, so as to control the connection and disconnection of the circuit.

[0028] The power distribution module is provided with a preset number of output interfaces and input interfaces. The output interfaces are directly connected to the charging interface, and the input interfaces are directly connected to the charging module. Each set of output interfaces and input interfaces is connected through a power switch, and each input interface is interconnected with other input interfaces through a power switch to reduce the number of power switches installed inside.

[0029] For example, to achieve the above objectives, this application also provides a charging pile power distribution device, the device comprising:

[0030] The acquisition module is used to acquire the power requirements of the charging interface;

[0031] The determination module is used to determine the charging module to be used based on the power requirement and the preset charging module power; wherein the charging module is connected to the charging interface to form a circuit through a preset power distribution module, and the power distribution module is provided with a power switch for controlling the circuit to be turned on and off;

[0032] The control module is used to control the closing of the power switch corresponding to the charging module within the power distribution module, so that the charging interface outputs power that meets the power requirements.

[0033] For example, to achieve the above objectives, this application also provides a charging pile power allocation device, the device comprising: a memory, a processor, and a charging pile power allocation program stored in the memory and executable on the processor, the charging pile power allocation program being configured to implement the steps of the charging pile power allocation method as described above.

[0034] For example, to achieve the above objectives, this application also provides a computer storage medium storing a charging pile power allocation program, which, when executed by a processor, implements the steps of the charging pile power allocation method as described above.

[0035] Compared to related technologies, current high-power multi-charging-interface DC charging piles employ a matrix power distribution scheme, which results in high installation costs. This application addresses this by obtaining the power requirements of the charging interfaces; determining the charging modules to be used based on these power requirements and a preset charging module power; wherein the charging modules are connected to the charging interfaces via a preset power distribution module to form a circuit; the power distribution module includes power switches for controlling the circuit's on / off state; and controlling the power switches within the power distribution module corresponding to the charging modules to be used to close, allowing the charging interfaces to output power that meets the power requirements. In other words, by setting up a power distribution module, the application determines the charging modules to be used based on the charging interface's power requirements and controls the power switches within the power distribution module corresponding to the charging modules to achieve the required charging power. This approach avoids the need for numerous power switches between the charging modules and the charging interfaces, thereby reducing the cost of the charging pile while ensuring that the charging pile's output power meets the charging interface's power requirements.

[0042] The realization of the purpose, functional features and advantages of this application will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0043] It should be understood that the specific embodiments described herein are merely illustrative of this application and are not intended to limit this application.

[0044] This application provides a power allocation method for charging piles, referring to... Figure 1 , Figure 1 This is a flowchart illustrating the first embodiment of the charging pile power allocation method of this application.

[0045] This application provides an embodiment of a charging pile power allocation method. It should be noted that although the logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in a different order. For ease of description, the following description of the execution entity and the various steps of the charging pile power allocation method are omitted. The charging pile power allocation method includes:

[0046] Step S110: Obtain the power requirement of the charging interface;

[0047] With the increasing popularity of new energy vehicles, the application of charging piles, which serve as the infrastructure for new energy vehicles, is also being promoted. Currently, high-power DC charging piles with multiple charging interfaces have become the preferred solution for most operators. However, due to the excessive number of power switches used in this solution, resources are wasted, and the construction cost of charging piles is increased.

[0048] Reference Figure 2 , Figure 2 A circuit diagram of a DC charging station with multiple charging interfaces.

[0049] according to Figure 2 It is known that existing charging piles with multiple charging interfaces are equipped with multiple charging interfaces and multiple charging modules, which are set as m and n respectively.

[0050] Each intersection of the horizontal and vertical lines represents a switching device (i.e., a power switch), and each charging module needs to be connected to both the positive and negative terminals when connected to the charging interface. Therefore, when the number of charging modules is n and the number of charging interfaces is m, the required number of power switches is 2*n*m.

[0051] In this application, the circuit and power distribution method used in this situation are improved to reduce the construction cost of the charging pile while ensuring that the charging pile can properly distribute the output power.

[0052] For example, a charging station is equipped with multiple charging ports. The following explanation will use the example of a charging station with n charging ports.

[0053] For example, when obtaining the power requirement of the charging interface, it is first determined which specific charging interface has the requirement, such as interface 1 or interface 2 out of 1 to n charging interfaces, or the simultaneous use of interface 1 and interface 2, etc.

[0054] The power requirement is usually determined by the specific battery that is connected to the charging interface.

[0055] Step S120: Determine the charging module to be used based on the power requirement and the preset charging module power; wherein, the charging module is connected to the charging interface to form a circuit through a preset power distribution module, and the power distribution module is equipped with a power switch for controlling the circuit to be turned on and off;

[0056] The preset charging module power is the hardware attribute of the charging module itself. When setting up the same charging pile, multiple charging modules with identical hardware attributes can be installed. That is, the output power of each charging module is limited to the same value. The output power is the preset charging module power, which can be determined according to the actual situation.

[0057] Based on the power requirements and the preset charging module power, the charging modules to be used can be determined. In determining the charging modules to be used, the position of the charging modules in the preset charging module layer and the number of charging modules to be used are determined, so as to facilitate the subsequent use of the charging modules.

[0058] The charging module determined by the power requirement and the preset charging module power is the charging module to be used. This module will be used as the power input of the charging pile, and the power will be output from the charging interface through the regulation of the power distribution module and related circuits.

[0059] The entire power output system of the charging pile includes: a charging module, a power distribution module, and a charging interface.

[0060] The charging module serves as the module that provides electrical energy.

[0061] Among them, the power distribution module, as a power switch control module, controls the power switches in the charging module and charging interface circuit to generate closed and open states, thereby controlling the output power of different charging interfaces and controlling the output power of the charging interfaces to adapt to power demand.

[0062] The charging interface serves as the power output terminal and is connected to the device to be charged.

[0063] For example, refer to Figure 3 , Figure 3 This is a schematic diagram of the power distribution module.

[0064] according to Figure 3 It can be seen that the power module has a preset number of output interfaces and input interfaces. The output interfaces are directly connected to the charging interface, and the input interfaces are directly connected to the charging module. Each set of output interfaces and input interfaces is connected through a power switch, and each input interface is interconnected with other input interfaces through a power switch.

[0065] in, Figure 3The left side serves as the input interface. Figure 3 The right side serves as the output interface.

[0066] The preset number is equal to the number of charging interfaces of the charging pile, so as to ensure that a power distribution module can connect and disconnect the circuit between the charging module and the charging interface by controlling the power switch. That is, each charging interface corresponds to at least one power distribution module and at least one directly connected charging module.

[0067] Each input interface is interconnected with other input interfaces via a power switch, meaning that each input interface can be connected in parallel with other input interfaces to output charging power together.

[0068] Step S130: Control the power switch in the power distribution module corresponding to the charging module to be used to close, so that the charging interface outputs power that meets the power requirements.

[0069] After the charging module is identified, its internal power switch is controlled by the power distribution module, thereby connecting the circuit formed by the charging module and the charging interface.

[0070] Specifically, when the power switch is closed by the power distribution module, the power switch at the corresponding position will be controlled. For example, by closing the power switch between the input interface and the output interface, the charging module can be directly connected to the charging interface at the corresponding position. Or by closing the power switch between multiple input interfaces that are connected in a cross manner, multiple charging modules can be connected in parallel and output power together.

[0071] Compared to related technologies, current high-power multi-charging-interface DC charging piles employ a matrix power distribution scheme, which results in high installation costs. This application addresses this by obtaining the power requirements of the charging interfaces; determining the charging modules to be used based on these power requirements and a preset charging module power; wherein the charging modules are connected to the charging interfaces via a preset power distribution module to form a circuit; the power distribution module includes power switches for controlling the circuit's on / off state; and controlling the power switches within the power distribution module corresponding to the charging modules to be used to close, allowing the charging interfaces to output power that meets the power requirements. In other words, by setting up a power distribution module, the application determines the charging modules to be used based on the charging interface's power requirements and controls the power switches within the power distribution module corresponding to the charging modules to achieve the required charging power. This approach avoids the need for numerous power switches between the charging modules and the charging interfaces, thereby reducing the cost of the charging pile while ensuring that the charging pile's output power meets the charging interface's power requirements.

[0072] For example, refer toFigure 4 , Figure 4 This is a flowchart illustrating the second embodiment of the charging pile power allocation method of this application. Based on the first embodiment of the charging pile power allocation method of this application described above, a second embodiment is proposed, wherein the method further includes:

[0073] Step S210: Calculate the required number of charging modules based on the power requirement and the preset charging module power;

[0074] Based on the power requirements and the preset power of the charging modules, the required number of charging modules can be calculated. For example, the power requirement is the total output power required when the charging interface charges the vehicle. This can be achieved by stacking multiple charging modules to ensure that the total output power meets the output requirements.

[0075] Based on the required quantity, the required number of charging modules can be determined from each module layer of the preset charging module layer and used as the charging modules to be used.

[0076] This demand can be calculated by dividing the power demand by the preset charging module power.

[0077] During the determination process, not only the required number of charging modules is determined, but also their locations. For example, the power distribution module has a preset number of input and output interfaces. Different groups of input and output interfaces will result in different charging interfaces directly connecting to different charging modules. Therefore, when scheduling the use of charging modules, it is necessary not only to calculate the required number of charging modules based on the power demand, but also to determine the location of the charging modules. Priority is given to selecting charging modules that are directly connected to the corresponding charging interface. If the output power of the directly connected charging module is insufficient, then a charging module connected in parallel with it is selected as the input.

[0078] Step S220: If the required quantity is greater than the quantity of each power distribution module, then determine the first power circuit directly connected to the charging interface and the second power circuit not directly connected from each power distribution module;

[0079] If the required quantity is greater than the quantity of each power distribution module, then a first power circuit directly connected to the charging interface and a second power circuit not directly connected are determined from each power distribution module.

[0080] Reference Figure 5 , Figure 5 This is a schematic diagram of the charging system structure of a charging pile.

[0081] Taking an example with n charging ports, the power distribution module has a total of n sets of input and output ports. Each power distribution module controls n charging modules. The number of power distribution modules can be set according to actual needs. Taking a set of k (at least 3) power distribution modules as an example, the explanation is as follows.

[0082] according to Figure 5 It can be seen that each of the n charging modules connected to the power distribution module corresponds one-to-one with a charging interface. For example, charging module 1 (the charging module in power distribution module 1) corresponds to charging interface 1, and charging module 2 (the charging module in power distribution module 2) corresponds to charging interface 1. That is, there are a total of k charging modules that directly correspond to any charging interface. All other cases are considered non-corresponding. For example, charging module 1 and charging interface 2 are non-corresponding.

[0083] The circuit in which the charging module and the charging interface have a corresponding relationship is the first power circuit. The first power circuit is a circuit composed of the charging interface and the charging module corresponding to the charging interface. The other non-corresponding circuits are the second power circuits. The second power circuits are circuits composed of the charging interface and the charging module that does not correspond to the charging interface.

[0084] When the number of required charging modules is calculated to be greater than k, it is necessary to call the charging modules corresponding to the charging interface, as well as the charging modules that do not correspond to the charging interface. In this case, the power distribution module needs to control the power switch of the parallel line to increase the number of charging modules put into use, thereby meeting the power requirements.

[0085] When the required number of charging modules is greater than k, it is necessary to connect both the first power circuit and the second power circuit to call up the charging modules that meet the quantity requirements.

[0086] For example, the step of determining the charging modules to be used based on the required quantity includes:

[0087] Step a: If the required quantity is not greater than the quantity of each power distribution module, then determine the first power circuit directly connected to the charging interface from each power distribution module;

[0088] Step b: Based on the required quantity, select a portion of the charging modules in the first power circuit as the charging modules to be used.

[0089] When controlling the power switch through the power distribution module, the charging module corresponding to the situation is selected as the charging module to be used. Thus, the power distribution module only needs to control the power switches that are directly connected to the input and output interfaces, without having to control the parallel power switches between the input interfaces, thereby improving response efficiency.

[0090] For example, if the number of required charging modules is no greater than k, the corresponding charging module can be directly selected as the charging module to be used. If the number of required charging modules is greater than k, other parallel charging modules need to be called.

[0091] Step S230: Based on the required quantity, select some charging modules from the first power circuit and some charging modules from the second power circuit as the charging modules to be used.

[0092] Depending on the required quantity, an appropriate number of charging modules need to be selected from the first power circuit and the second power circuit respectively. For example, if there are k charging modules in the first power circuit and the required quantity is 2k, then k charging modules from the first power circuit and k charging modules from the second power circuit need to be called to meet the power requirements of the charging interface.

[0093] For example, the step of selecting a portion of the charging modules in the first power circuit and a portion of the charging modules in the second power circuit as the charging modules to be used based on the required quantity includes:

[0094] Step c: Based on the required quantity, select the charging modules in the first power circuit in ascending order of the preset numbers of each power distribution module, and select some charging modules in the second power circuit in descending order of the preset numbers.

[0095] When selecting charging modules based on the required quantity, the selection order will vary depending on the circuit in which the charging module is located.

[0096] For example, a charging pile may be equipped with k power distribution modules. When using these power distribution modules, the corresponding second power circuits in multiple power distribution modules can be used simultaneously. For example, using... Figure 5 Charging modules 1 and 2 in power distribution module 1, and charging modules 1 and 2 in power distribution module 2, are output to charging interface 1. If charging interface 2 has increased power demand, charging module 2 in power distribution module 1 and power distribution module 2 should be prioritized as the output of charging interface 2. However, since charging module 2 is already being used as the output of charging interface 1, closing the power switch between charging module 2 and charging interface 2 will cause the output power of charging module 2 to be simultaneously distributed to charging interface 1 and charging interface 2. As a result, the output power of charging interface 1 and charging interface 2 will not be able to meet the power demand, affecting the use of the charging pile. Therefore, it is necessary to determine the appropriate order of charging module selection when the charging interface outputs power.

[0097] Before determining the selection order of the charging modules, first determine the sequential numbering of the power distribution modules, then... Figure 5 In this way, multiple power distribution modules are numbered 1, 2, 3...k from top to bottom.

[0098] When selecting charging modules, the charging modules in the first power circuit are selected in ascending order of their preset numbers, and the charging modules in the second power circuit are selected in descending order of their preset numbers.

[0099] For example, the step of selecting a portion of the charging modules in the second power circuit in descending order of the preset numbers includes:

[0100] Step d: Select the charging module in all the second power circuits corresponding to the power distribution module with the largest number, according to the preset number;

[0101] Step e: If the number of charging modules does not meet the required number, then according to the preset number in descending order, the charging modules in the second power circuit corresponding to the remaining power distribution modules are selected sequentially until the number of charging modules meets the required number.

[0102] Based on the selection order and preset numbering established above, the charging modules in the first power circuit and the second power circuit can be selected starting from the largest and smallest numbers, respectively.

[0103] When selecting charging modules in the second power circuit, first determine the power allocation module with the largest number, and then select an appropriate number of charging modules from the second power circuit corresponding to the power allocation module with the largest number.

[0104] After all the charging modules in the second power circuit of the power distribution module with the highest number have been selected, the charging modules are then selected from the other power distribution modules in descending order until the total number of selected charging modules meets the required quantity.

[0105] For example, the maximum number is k. After all the charging modules in the power distribution module k have been selected, the corresponding charging module is then selected from the power distribution module (k-1).

[0106] After selecting the charging module in the second power circuit, the second power module that has been put into use is marked and no longer used. When connecting other charging interfaces, the charging modules are selected in order of preset number from smallest to largest to avoid the output power being evenly distributed among multiple charging interfaces.

[0107] Step f: Select the obtained charging module as the charging module to be used.

[0108] After selecting a portion of the charging modules based on the required quantity, these charging modules will be used as the charging modules to be used.

[0109] In summary, when a charging port needs to connect to a charging module, the charging modules corresponding to the current charging port are allocated in ascending order of their preset numbers according to the power allocation module. Then, the charging modules not corresponding to the current charging port are allocated in descending order of their preset numbers according to the power allocation module.

[0110] In this embodiment, if the required quantity is greater than the number of each power distribution module, a first power circuit directly connected to the charging interface and a second power circuit not directly connected are determined from the power distribution modules. Based on the required quantity, some charging modules in the first power circuit and some charging modules in the second power circuit are selected as charging modules to be used. That is, when selecting charging modules, charging modules directly connected to the charging interface in the first power circuit are given priority. When the number of charging modules in the first power circuit cannot meet the required quantity, a corresponding number of charging modules are selected from the second power circuit. This achieves the effect of power distribution scheduling with a smaller number of power switches, reducing costs, reducing the complexity of parallel circuits, and reducing the difficulty of subsequent maintenance of charging piles.

[0111] For example, based on the first and second embodiments of the charging pile power allocation method described in this application, a third embodiment is proposed, wherein the method further includes:

[0112] Step g: When the charging interface is detected to be no longer in use, release the charging modules corresponding to the charging interface in the reverse order of when the charging modules were selected.

[0113] Once the charging interface is detected as no longer in use, the output connection of the charging module needs to be disconnected, i.e., the charging module needs to be released.

[0114] When the charging interface needs to release the charging module, the charging modules that are not corresponding to the current charging interface are released in order of power distribution module number from smallest to largest, and then the charging modules corresponding to the current charging interface are released in order of power distribution module number from largest to smallest.

[0115] That is, the release process of the charging module is the reverse of the order in which the charging module is connected to the charging interface.

[0116] In this embodiment, when the charging interface is detected to be no longer in use, the charging modules corresponding to the charging interface are released sequentially in the reverse order of selecting the charging modules. That is, corresponding control steps for releasing the charging modules are formulated so that the entire charging pile can normally connect the charging modules to the charging interface and normally release the charging modules, ensuring the normal operation of the charging pile.

[0117] In addition, this application also provides a charging pile power distribution system, which includes a charging module, a power distribution module, and a charging interface:

[0118] The charging module is used to provide corresponding electrical energy. When the charging module is connected to the charging interface, the charging module acts as a module that outputs electrical energy.

[0119] The charging interface is used to receive electrical energy output by the charging module and output it to the outside.

[0120] The power distribution module is used to control the connection and disconnection of the power switch in the circuit formed by the charging module and the charging interface, so as to control the connection and disconnection of the circuit.

[0121] The power distribution module is provided with a preset number of output interfaces and input interfaces. The output interfaces are directly connected to the charging interface, and the input interfaces are directly connected to the charging module. Each set of output interfaces and input interfaces is connected through a power switch, and each input interface is interconnected with other input interfaces through a power switch to reduce the number of power switches installed inside.

[0122] In addition, this application also provides a charging pile power distribution device, which includes:

[0123] The acquisition module is used to acquire the power requirements of the charging interface;

[0124] The determination module is used to determine the charging module to be used based on the power requirement and the preset charging module power; wherein the charging module is connected to the charging interface to form a circuit through a preset power distribution module, and the power distribution module is provided with a power switch for controlling the circuit to be turned on and off;

[0125] The control module is used to control the closing of the power switch corresponding to the charging module within the power distribution module, so that the charging interface outputs power that meets the power requirements.

[0126] For example, the determining module includes:

[0127] The calculation submodule is used to calculate the required number of charging modules based on the power requirements and the preset charging module power.

[0128] The first determining submodule is used to determine, if the required quantity is greater than the quantity of each power distribution module, a first power circuit directly connected to the charging interface and a second power circuit not directly connected to the charging interface from each power distribution module.

[0129] The first selection submodule is used to select, according to the required quantity, a portion of the charging modules in the first power circuit and the second power circuit as the charging modules to be used.

[0130] The second determining submodule is used to determine, if the required quantity is not greater than the number of each power distribution module, a first power circuit directly connected to the charging interface from each power distribution module.

[0131] The second selection submodule is used to select a portion of the charging modules in the first power circuit as the charging modules to be used, based on the required quantity.

[0132] For example, the first selection submodule includes:

[0133] The first selection unit is used to select charging modules in the first power circuit in ascending order of the preset numbers of each power distribution module according to the required quantity, and to select some charging modules in the second power circuit in descending order of the preset numbers.

[0134] A determining unit is used to select the charging module as the charging module to be used.

[0135] For example, the first selection unit includes:

[0136] The first selection subunit is used to select the charging module in all the second power circuits corresponding to the power distribution module with the largest number according to the preset number;

[0137] The second selection subunit is used to select, in descending order of the preset numbers, the charging modules in the second power circuit corresponding to the remaining power distribution modules if the number of charging modules does not meet the required number, until the number of charging modules meets the required number.

[0138] The specific implementation method of the charging pile power distribution device in this application is basically the same as the embodiments of the charging pile power distribution method described above, and will not be repeated here.

[0139] In addition, this application also provides a power distribution device for a charging pile. For example... Figure 6 As shown, Figure 6 This is a schematic diagram of the hardware operating environment involved in the embodiments of this application.

[0140] For example, Figure 6 This is a schematic diagram of the hardware operating environment for the power distribution equipment of a charging pile.

[0141] like Figure 6 As shown, the charging pile power distribution device may include a processor 601, a communication interface 602, a memory 603, and a communication bus 604.
