Description

Technical Field

[0001] This application relates to the field of charging equipment, and more particularly to a charging device, a charging control method, and a computing device. Background Technology

[0002] A charging stack is a centralized charging device that can achieve dynamic power distribution to multiple charging objects by integrating multiple charging modules and multiple charging guns.

[0003] In related technologies, charging devices can distribute charging power using a matrix topology. A matrix topology arranges charging modules in a matrix, with each module interconnected in rows and columns, and the connections are controlled by relays to achieve power distribution.

[0004] However, the above method requires a large number of relays to meet the connection between the matrix topology, which increases the number of failure points in the system and leads to poor stability of the charging equipment. Summary of the Invention

[0005] This application provides a charging device, a charging control method, and a computing device, which can improve the stability of the charging device.

[0006] In a first aspect, embodiments of this application provide a charging device, including multiple charging modules and multiple charging guns. A second charging module is connected to a fourth charging module via a switching circuit corresponding to the fourth charging module. The multiple charging modules include a first charging module, a second charging module, a third charging module, and a fourth charging module corresponding to the charging gun. The charging gun is connected to the first charging module; the charging gun is connected to the second charging module via a switching circuit corresponding to the second charging module; the charging gun is connected to the third charging module via a switching circuit corresponding to the third charging module; the charging gun is connected to the fourth charging module via switching circuits corresponding to the third and fourth charging modules; and the second charging module is connected to the fourth charging module via a switching circuit corresponding to the fourth charging module.

[0007] This application provides a charging device in which any one charging gun can be connected to multiple charging modules. When the power of the first charging module cannot meet the power requirements of the charging gun, sufficient power can be provided to the charging gun through the connection between the second, third, and fourth charging modules. Furthermore, compared to a method where each charging gun and each charging module has a corresponding switching circuit, the number of switching circuits is reduced, thus reducing potential points of failure in the charging device and improving its stability.

[0008] In one possible implementation,

[0009] The charging gun is connected to the first charging module via a first line;

[0010] The charging gun is connected to the second charging module through the corresponding switching circuit and the first line.

[0011] In the above method, the first charging module and the second charging module are connected to the charging gun through the first line, so that both the first charging module and the second charging module can supply power to the charging gun, thereby improving the efficiency of the charging equipment.

[0012] In one possible implementation, the charging gun is connected to one end of the first line;

[0013] The other end of the first line is connected to one end of the switching circuit corresponding to the first charging module and the second charging module, respectively.

[0014] The other end of the switching circuit corresponding to the second charging module is connected to the second charging module.

[0015] The above method can reduce the number of switching circuits, reduce the failure points of the charging equipment, and thus improve the stability of the charging equipment.

[0016] In one possible implementation, the charging gun is connected to the third charging module via a second line and a corresponding switching circuit for the third charging module.

[0017] The charging gun is connected to the fourth charging module through the second line, the switching circuit corresponding to the third charging module, and the switching circuit corresponding to the fourth charging module.

[0018] In the above method, the third and fourth charging modules can be connected to the charging gun via the second line, so that both the third and fourth charging modules can supply power to the charging gun, thereby improving the efficiency of the charging equipment.

[0019] In one possible implementation, the charging gun is connected to one end of the switching circuit corresponding to the third charging module, and the other end of the switching circuit corresponding to the third charging module is connected to one end of the second line.

[0020] The other end of the second line is connected to one end of the switching circuit corresponding to the third charging module and the fourth charging module, respectively, and the other end of the switching circuit corresponding to the fourth charging module is connected to the fourth charging module.

[0021] The above method can reduce the number of switching circuits, reduce the failure points of the charging equipment, and thus improve the stability of the charging equipment.

[0022] In one possible implementation, the number of multiple charging modules and multiple charging guns are both M, where M is an integer greater than 1.

[0023] The first charging module corresponding to the i-th charging gun is the i-th charging module among multiple charging modules, where i is a positive integer less than or equal to M.

[0024] The above method can uniquely identify the first charging module corresponding to the charging gun, thus improving the stability of the charging equipment.

[0025] In one possible implementation, the number of multiple charging modules and multiple charging guns are M, where M is an even number greater than 1;

[0026] The number of the first charging modules corresponding to the charging gun is 1;

[0027] The number of second charging modules corresponding to the charging gun is

[0028] The number of third charging modules corresponding to the charging gun is 1;

[0029] The number of fourth charging modules corresponding to the charging gun is

[0030] Each second charging module is connected via a corresponding switching circuit.

[0031] Each fourth charging module is connected via a corresponding switching circuit.

[0032] The adjacent second and fourth charging modules are connected through the corresponding switching circuit of the fourth charging module.

[0033] The above method can determine the number of the first charging module, the second charging module, the third charging module, and the fourth charging module corresponding to the charging gun, thereby improving the stability of the charging equipment.

[0034] Secondly, embodiments of this application provide a charging control method, including: obtaining a charging request corresponding to a charging gun, wherein the charging request includes a target charging power corresponding to the charging gun;

[0035] Determine the first charging power of the first charging module corresponding to the charging gun;

[0036] When the first charging power is greater than or equal to the target charging power, the first charging module is controlled to charge the target object through the charging gun.

[0037] When the first charging power is less than the target charging power, the target charging module is determined from among multiple charging modules based on the first charging power, the target charging power, the working status of each charging module in the charging device, and the priority between each charging module. The first charging module and the target charging module are then controlled to charge the target object through the charging gun. The working status is either occupied or idle.

[0038] In a charging control method provided in this application embodiment, when power needs to be supplied to a device to be charged via a charging gun, the charging request corresponding to the charging gun can be obtained first to determine the target charging power required by the charging gun; the first charging power of the first charging module corresponding to the charging gun can be determined; it can be determined whether the first charging power is greater than or equal to the target charging power. If the first charging power is greater than or equal to the target charging power, the first charging module is controlled to charge the target object through the charging gun; if the first charging power is less than the target charging power, the target charging module is determined from multiple charging modules based on the first charging power, the target charging power, the working status of each charging module in the charging device, and the priority between each charging module, and the first charging module and the target charging module are controlled to charge the target object through the charging gun. In this way, compared with the method of supplying power only through the charging module corresponding to the charging gun, in this solution, when the first charging module corresponding to the charging gun does not meet the target charging power, the charging gun can be supplied power through the second, third, and / or fourth charging modules corresponding to the charging gun according to the priority order, thereby improving the efficiency and stability of the charging device.

[0039] In one possible implementation, the priority of the second charging module corresponding to the charging gun is higher than the priority of the third charging module corresponding to the charging gun.

[0040] The priority of the third charging module corresponding to the charging gun is higher than the priority of the fourth charging module corresponding to the charging gun.

[0041] The above method improves the efficiency of charging control by setting priorities.

[0042] In one possible implementation, the number of second charging modules corresponding to the charging gun is multiple; based on the first charging power, the target charging power, the operating status of each charging module in the charging device, and the priority among the charging modules, the target charging module is determined from the multiple charging modules, including:

[0043] The difference between the target charging power and the first charging power is determined as the first remaining power;

[0044] Determine the working status of each second charging module corresponding to the charging gun;

[0045] If there is an idle second charging module among the multiple second charging modules corresponding to the charging gun, the target charging module is determined among the idle second charging modules based on the first remaining power and the charging power of each idle second charging module.

[0046] If there is no idle second charging module among the multiple second charging modules corresponding to the charging gun, the target charging module is determined from the third and / or fourth charging modules corresponding to the charging gun based on the first remaining power.

[0047] In the above method, when the first charging power cannot reach the target charging power, the target charging module for powering the charging gun is determined by the first remaining power, which ensures that the charging gun can provide the target charging power to the device to be charged, thereby improving the efficiency of the charging device.

[0048] In one possible implementation, determining the target charging module among the idle second charging modules based on the first remaining power and the charging power of each idle second charging module includes:

[0049] The sum of the charging power of the second charging module in the idle state is determined as the second charging power;

[0050] If the second charging power is less than the first remaining power, then the idle second charging module is identified as a part of the target charging modules. Based on the first remaining power and the second charging power, another part of the target charging modules is identified in the third and / or fourth charging modules corresponding to the charging gun.

[0051] If the second charging power is greater than or equal to the first remaining power, then the target charging module is determined from the idle second charging modules based on the total output power and total charging time of each idle second charging module.

[0052] In the above method, if there is an idle second charging module, the target charging module is determined in the second charging module, thereby improving the efficiency of the charging equipment.

[0053] In one possible implementation, based on the total output power and total charging time of each idle second charging module, a target charging module is determined among the idle second charging modules, including:

[0054] When the number of idle second charging modules is equal to 1, the idle second charging module is identified as the target charging module;

[0055] When the number of idle second charging modules is greater than 1 and the number of idle second charging modules is N, the utilization rate of the N second charging modules is determined sequentially based on the total output power and the total charging time.

[0056] Based on the utilization rate and the first remaining power of the N second charging modules, the target charging module is determined from the idle second charging modules.

[0057] In the above method, when the number of idle second charging modules is equal to 1, that is, the second charging module can meet the first remaining power, which can meet the target charging power of the charging gun; when the number of idle second charging modules is greater than 1, according to the utilization rate of the charging modules, if the power is met, the second charging module with a low utilization rate is preferentially selected for power supply, thereby improving the power balance of the charging equipment.

[0058] In one possible implementation, based on the first remaining power and the second charging power, another portion of the target charging modules is determined from the third and / or fourth charging modules corresponding to the charging gun, including:

[0059] The difference between the first remaining power and the second charging power is determined as the second remaining power;

[0060] Determine the working status of each third charging module corresponding to the charging gun;

[0061] If there is an idle third charging module among the multiple third charging modules corresponding to the charging gun, the target charging module is determined among the idle third charging modules based on the second remaining power and the charging power of each idle third charging module.

[0062] If there is no idle third charging module among the multiple third charging modules corresponding to the charging gun, the target charging module is determined among the fourth charging modules corresponding to the charging gun based on the second remaining power.

[0063] In the above method, if the power provided by the second charging module still does not meet the target charging power, the third charging module and / or the fourth charging module can be used to power the charging gun.

[0064] In one possible implementation, the method further includes obtaining the current charging energy reached by the charging gun;

[0065] When the current charging energy is greater than or equal to the preset charging energy, power supply to the charging gun is stopped according to the reverse order of priority among the target charging modules.

[0066] In the above method, when the preset charging energy is reached, in order to protect the health of the battery of the device to be charged, the power supply is gradually withdrawn in reverse order of priority, thereby improving the stability of the charging device and the battery of the device to be charged.

[0067] Thirdly, embodiments of this application provide a charging control device, including: an acquisition module, a determination module, a first control module, and a second control module, wherein...

[0068] The acquisition module is specifically used to acquire the charging request corresponding to the charging gun, and the charging request includes the target charging power corresponding to the charging gun.

[0069] The module is specifically used to determine the first charging power of the first charging module corresponding to the charging gun.

[0070] The first control module is specifically used to control the first charging module to charge the target object through the charging gun when the first charging power is greater than or equal to the target charging power.

[0071] The second control module is specifically used to, when the first charging power is less than the target charging power, determine the target charging module among multiple charging modules based on the first charging power, the target charging power, the working status of each charging module in the charging device, and the priority between each charging module, and control the first charging module and the target charging module to charge the target object through the charging gun, with the working status being either occupied or idle.

[0072] In a charging control device provided in this application embodiment, when power needs to be supplied to a device to be charged via a charging gun, the charging request corresponding to the charging gun can be obtained first to determine the target charging power required by the charging gun; the first charging power of the first charging module corresponding to the charging gun can be determined; it can be determined whether the first charging power is greater than or equal to the target charging power. If the first charging power is greater than or equal to the target charging power, the first charging module is controlled to charge the target object through the charging gun; if the first charging power is less than the target charging power, the target charging module is determined from multiple charging modules based on the first charging power, the target charging power, the working status of each charging module in the charging device, and the priority between each charging module, and the first charging module and the target charging module are controlled to charge the target object through the charging gun. In this way, compared with the method of supplying power only through the charging module corresponding to the charging gun, in this solution, when the first charging module corresponding to the charging gun does not meet the target charging power, the charging gun can be supplied with power through the second, third, and / or fourth charging modules corresponding to the charging gun according to the priority order, thereby improving the efficiency and stability of the charging device.

[0073] In one possible implementation, the priority of the second charging module corresponding to the charging gun is higher than the priority of the third charging module corresponding to the charging gun.

[0074] The priority of the third charging module corresponding to the charging gun is higher than the priority of the fourth charging module corresponding to the charging gun.

[0075] The above method can improve the efficiency of charging control by setting priorities.

[0076] In one possible implementation, the second control module is specifically used for,

[0077] The difference between the target charging power and the first charging power is determined as the first remaining power;

[0078] Determine the working status of each second charging module corresponding to the charging gun;

[0079] If there is an idle second charging module among the multiple second charging modules corresponding to the charging gun, the target charging module is determined among the idle second charging modules based on the first remaining power and the charging power of each idle second charging module.

[0080] If there is no idle second charging module among the multiple second charging modules corresponding to the charging gun, the target charging module is determined from the third and / or fourth charging modules corresponding to the charging gun based on the first remaining power.

[0081] In the above method, when the first charging power cannot reach the target charging power, the target charging module for powering the charging gun is determined by the first remaining power, which ensures that the charging gun can provide the target charging power to the device to be charged, thereby improving the efficiency of the charging device.

[0082] In one possible implementation, the second control module is specifically used for,

[0083] The sum of the charging power of the second charging module in the idle state is determined as the second charging power;

[0084] If the second charging power is less than the first remaining power, then the idle second charging module is identified as a part of the target charging modules. Based on the first remaining power and the second charging power, another part of the target charging modules is identified in the third and / or fourth charging modules corresponding to the charging gun.

[0085] If the second charging power is greater than or equal to the first remaining power, then the target charging module is determined from the idle second charging modules based on the total output power and total charging time of each idle second charging module.

[0086] In the above method, if there is an idle second charging module, the target charging module is determined in the second charging module, thereby improving the efficiency of the charging equipment.

[0087] In one possible implementation, the second control module is specifically used for,

[0088] When the number of idle second charging modules is equal to 1, the idle second charging module is identified as the target charging module;

[0089] When the number of idle second charging modules is greater than 1 and the number of idle second charging modules is N, the utilization rate of the N second charging modules is determined sequentially based on the total output power and the total charging time.

[0090] Based on the utilization rate and the first remaining power of the N second charging modules, the target charging module is determined from the idle second charging modules.

[0091] In the above method, when the number of idle second charging modules is equal to 1, that is, the second charging module can meet the first remaining power, which can meet the target charging power of the charging gun; when the number of idle second charging modules is greater than 1, according to the utilization rate of the charging modules, if the power is met, the second charging module with a low utilization rate is preferentially selected for power supply, thereby improving the power balance of the charging equipment.

[0094] Determine the working status of each third charging module corresponding to the charging gun;

[0095] If there is an idle third charging module among the multiple third charging modules corresponding to the charging gun, the target charging module is determined among the idle third charging modules based on the second remaining power and the charging power of each idle third charging module.

[0096] If there is no idle third charging module among the multiple third charging modules corresponding to the charging gun, the target charging module is determined among the fourth charging modules corresponding to the charging gun based on the second remaining power.

[0097] In the above method, if the power provided by the second charging module still does not meet the target charging power, the third charging module and / or the fourth charging module can be used to power the charging gun.

[0182] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with those of this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of the embodiments of this application as detailed in the appended claims.

[0183] To facilitate understanding, the following will be combined with... Figure 1 The application scenarios involved in the embodiments of this application are described below.

[0184] Figure 1 For a schematic diagram of the architecture of a charging device provided in an embodiment of this application, please refer to [link / reference]. Figure 1 This includes: a charging device, a device to be charged 1, a device to be charged 2, a device to be charged 3, and a device to be charged N. Figure 1 In the architecture shown, the charging equipment can include multiple charging modules and multiple charging guns. The charging modules can convert AC power into DC power that can charge the device to be charged. Each charging gun can correspond one-to-one with a device to be charged, and the charging gun can charge the device to be charged with the DC power provided by the charging modules. The device to be charged can refer to an electric vehicle or similar device.

[0185] It should be noted that, Figure 1 This is merely an example to illustrate the architecture of a charging device, and is not intended to limit the scope of such an architecture.

[0186] In this embodiment, the charging device may include multiple charging modules and multiple charging guns. The multiple charging modules may include a first charging module, a second charging module, a third charging module, and a fourth charging module corresponding to the charging gun. The charging gun can be connected to the first charging module, and can also be connected to the second charging module via a corresponding switching circuit. The charging gun can also be connected to the third charging module via a corresponding switching circuit, and finally to the fourth charging module via switching circuits corresponding to both the third and fourth charging modules. This allows any single charging gun to be connected to multiple charging modules. When the power of the first charging module is insufficient to meet the power requirements of the charging gun, sufficient power can be provided to the charging gun through the connections between the second, third, and fourth charging modules. Furthermore, compared to having a corresponding switching circuit between each charging gun and each charging module, this reduces the number of switching circuits, thus reducing potential points of failure in the charging device and improving its stability.

[0210] The charging device 20 of this application embodiment includes: a plurality of charging modules 21 and a plurality of charging guns 22. The plurality of charging modules 21 include: a first charging module 211, a second charging module 212, a third charging module 213 and a fourth charging module 214 corresponding to the charging gun 22. The charging gun 22 is connected to the first charging module 211.

To ensure the output voltage matches the battery charging requirements and achieves input-output electrical isolation, improving system safety, the AC / DC rectifier module rectifies the high-frequency AC power back into DC power for subsequent DC / DC conversion. The DC / DC converter module adjusts and stabilizes the voltage and current of the rectified DC power, outputting charging voltage and current that meet the battery's characteristics. The output filter module filters the DC / DC module output, reducing voltage and current ripple and ensuring a stable and clean output DC level. The monitoring and protection module monitors input and output voltage, current, temperature, and other parameters in real time and is equipped with overvoltage, undervoltage, overcurrent, short circuit, and overtemperature protection functions to ensure a safe and reliable charging process. The charging module can also include other IGBT or MOSFET modules, as long as they can convert the input voltage to a voltage usable by the device being charged. No specific limitations are placed on the power modules included in the charging module. The charging gun 22 can be connected to the device being charged to provide it with the necessary power. In this way, the charging device can supply power to the device to be charged through multiple charging modules 21 and multiple charging guns 22. At the same time, compared with the method of connecting each charging module through a switching circuit, this solution reduces the number of switching circuits (i.e., reduces the number of fault nodes) and improves the stability of the charging device 20.

[0223] Figure 8 This is a schematic flowchart illustrating a charging control method provided in an embodiment of this application. Please refer to... Figure 8 The method may include:

[0224] S801, Obtain the charging request corresponding to the charging gun.

[0225] The execution entity in this application embodiment can be a charging device or a charging control device installed in the charging device. The charging device can be a charging pile, charging stack, or other similar equipment. The charging control device can be implemented through software or through a combination of software and hardware.

[0226] The charging request includes the target charging power corresponding to the charging gun. Users can connect the charging gun to the device to be charged, and the charging gun can obtain the target charging power required by the device. For example, the target charging power could be 60kW.

[0227] S802. Determine the first charging power of the first charging module corresponding to the charging gun.

[0228] The first charging power can be the charging power provided by the first charging module or the charging gun.

[0229] For example, the first charging power can be 30kW.

[0230] S803. Determine whether the first charging power is greater than or equal to the target charging power.

[0231] If so, then execute S804.

[0232] If not, then execute S805.

[0233] S804. Control the first charging module to charge the target object through the charging gun.

[0234] When the first charging power can meet the target charging power required by the charging gun, the charging gun is powered only through the first charging module.

[0235] S805. Based on the first charging power, the target charging power, the working status of each charging module in the charging device, and the priority between each charging module, determine the target charging module among multiple charging modules, and control the first charging module and the target charging module to charge the target object through the charging gun.

[0236] The priority among the charging modules can refer to the fact that when the first charging power of the first charging module corresponding to the charging gun does not meet the target charging power, the charging modules corresponding to the charging gun can supply power to the charging gun according to their priority.

[0237] The priority among the charging modules corresponding to any given charging gun can be as follows: the priority of the second charging module corresponding to the charging gun is higher than the priority of the third charging module corresponding to the charging gun; the priority of the third charging module corresponding to the charging gun is higher than the priority of the fourth charging module corresponding to the charging gun.

[0238] Specifically, when the first charging power corresponding to the charging gun does not meet the target charging power, the charging gun is first powered by the second charging module corresponding to the charging gun. When the second charging module corresponding to the charging gun is occupied, or when the second charging power of the second charging module corresponding to the charging gun plus the first charging power still cannot meet the target charging power, the charging gun is then powered by the third charging module and / or the fourth charging module.

[0239] Each charging module can be in either an occupied or idle state. Specifically, for any given charging module, the occupied state means that the charging module is supplying power to the charging gun, while the idle state means that the charging module is not supplying power to the charging gun.

[0240] The target charging module can refer to the charging module that supplies power to the charging gun among the second, third, and / or fourth charging modules corresponding to the charging gun when the first charging module corresponding to the charging gun cannot meet the target charging power.

[0241] Optionally, after controlling the first charging module and the target charging module to charge the target object through the charging gun, the method further includes: acquiring the current charging energy reached by the charging gun; when the current charging energy is greater than or equal to a preset charging energy, stopping the power supply to the charging gun according to the reverse order of priority among the target charging modules. The preset charging energy is a value pre-set by the user within the charging device. For example, the preset charging energy can be 90% of the total charging energy.

[0242] For example, assuming the current target charging module includes multiple second charging modules, multiple third charging modules, and multiple fourth charging modules, if the current charging energy reached by the current charging gun is greater than or equal to the preset charging energy, then in reverse order of priority, the multiple fourth charging modules are first stopped supplying power to the charging gun, then the multiple third charging modules are stopped supplying power to the charging gun, and finally the multiple second charging modules are stopped supplying power to the charging gun, until the charging gun is detected to have reached the total charging energy, at which point the first charging module stops supplying power to the charging gun.

[0243] exist Figure 8 In the illustrated embodiment, when power needs to be supplied to the device to be charged via the charging gun, the charging request corresponding to the charging gun can be obtained first to determine the target charging power required by the charging gun; the first charging power of the first charging module corresponding to the charging gun can be determined; it can be determined whether the first charging power is greater than or equal to the target charging power. If the first charging power is greater than or equal to the target charging power, the first charging module is controlled to charge the target object through the charging gun; if the first charging power is less than the target charging power, the target charging module is determined from multiple charging modules based on the first charging power, the target charging power, the working status of each charging module in the charging device, and the priority between each charging module, and the first charging module and the target charging module are controlled to charge the target object through the charging gun. In this way, compared with the method of supplying power only through the charging module corresponding to the charging gun, in this solution, when the first charging module corresponding to the charging gun does not meet the target charging power, the charging gun can be supplied power through the second, third, and / or fourth charging modules corresponding to the charging gun according to the priority order, thereby improving the efficiency and stability of the charging device.

[0244] Based on the above embodiments, the following, in conjunction with Figure 9 The process of determining the target charging module ( Figure 8 The S805 example will be described in detail.

[0245] Figure 9 This is a schematic diagram illustrating the process of determining the target charging module provided in an embodiment of this application. Please refer to... Figure 9 The method may include:

[0246] S901. When the first charging power is less than the target charging power, the difference between the target charging power and the first charging power is determined as the first remaining power.

[0247] For example, assuming the first charging power is 30kW and the target charging power is 60kW, then the first remaining power is 30kW.

[0248] S902. Determine whether there is an idle second charging module in each of the second charging modules corresponding to the charging gun.

[0249] If so, then execute S903.

[0250] If not, then execute S910.

[0251] S903. The sum of the charging power of the second charging module in the idle state is determined as the second charging power.

[0252] For example, assuming that there are currently two idle charging modules, namely the second charging module 1, the second charging module 2, and the second charging module 3, the charging power of the second charging module 1 is 15kW, the charging power of the second charging module 2 is 30kW, and the charging power of the second charging module 3 is 20kW, then the total charging power is 65kW.

[0253] S904. Determine whether the second charging power is less than the first remaining power.

[0254] If so, then execute S905.

[0255] If not, then execute S906.

[0256] S905. Identify the idle second charging module as a part of the target charging modules, and based on the first remaining power and the second charging power, identify another part of the target charging modules in the third and / or fourth charging modules corresponding to the charging gun.

[0257] Another set of target charging modules can be determined from the third and / or fourth charging modules corresponding to the charging gun in the following ways: the difference between the first remaining power and the second charging power is determined as the second remaining power; the working state of each third charging module corresponding to the charging gun is determined; if there is an idle third charging module among the multiple third charging modules corresponding to the charging gun, the target charging module is determined from the idle third charging modules based on the second remaining power and the charging power of each idle third charging module; if there is no idle third charging module among the multiple third charging modules corresponding to the charging gun, the target charging module is determined from the fourth charging module corresponding to the charging gun based on the second remaining power.

[0258] The process of determining the target charging module among the idle third charging modules, based on the second remaining power and the total charging power of each idle third charging module, further includes: determining the sum of the charging power of each idle third charging module as the third charging power; if the third charging power is greater than or equal to the second remaining power, determining the utilization rate of each third charging module based on the total output power and total charging time of each third charging module; sorting the third charging modules in ascending order according to their utilization rates, and determining the first i third charging modules as the target charging modules, wherein the sum of the charging power of the first i-1 third charging modules is less than the second remaining power. The remaining power is determined by the sum of the charging power of the first i third charging modules being greater than or equal to the second remaining power. If the third charging power is less than the second remaining power, then the idle third charging module is identified as the target charging module, and the difference between the third charging power and the second remaining power is identified as the third remaining power. The idle fourth charging modules are identified and sorted in ascending order according to their usage rate. The first i fourth charging modules are identified as the target charging modules in this order. The sum of the charging power of the first i-1 fourth charging modules is less than the third remaining power, and the sum of the charging power of the first i fourth charging modules is greater than or equal to the third remaining power.

[0259] The determination of the target charging module in the fourth charging module corresponding to the charging gun based on the second remaining power also includes: determining the fourth charging module that is in an idle state, sorting the fourth charging modules in ascending order according to their usage rate, and determining the first i fourth charging modules as the target charging modules in order, wherein the sum of the charging power of the first i-1 fourth charging modules is less than the second remaining power, and the sum of the charging power of the first i fourth charging modules is greater than or equal to the second remaining power.

[0260] The utilization rate of a charging module can be determined as follows: For any charging module, assuming the total charging time is x, the total output energy is y, the weighting coefficient for the total charging time is n, and the weighting coefficient for the total output energy is m, then the utilization rate K can be expressed as:

[0261] K = nx + my

[0262] The weighting coefficient n for the total charging time of the charging module and the weighting coefficient m for the total output power of the charging module are values ​​set by the user in advance. For example, n can be 0.3 and m can be 0.7.

[0263] S906. Determine whether the number of second charging modules in the idle state is equal to 1.

[0264] If so, then execute S907.

[0265] If not, then execute S908.

[0266] S907. Identify the idle second charging module as the target charging module.

[0267] S908. Based on the total output power and total charging time of each second charging module, determine the utilization rate of each second charging module in sequence.

[0268] S909. Based on the utilization rate and first remaining power of each second charging module, determine the target charging module among the idle second charging modules.

[0269] S910. Based on the first remaining power, determine the target charging module among the third and / or fourth charging modules corresponding to the charging gun.

[0270] The execution process of steps S908-S910 can be referred to step S905, and will not be repeated here.

[0271] exist Figure 9In the illustrated embodiment, when power needs to be supplied to the device to be charged via the charging gun, if the first charging power of the first charging module is less than the target charging power, the target charging module can be selected from the second, third, and / or fourth charging modules to supply power to the charging gun. The difference between the target charging power and the first charging power can be determined as the first remaining power; it is determined whether there are any idle second charging modules in each of the second charging modules corresponding to the charging gun. If there are idle second charging modules, the sum of the charging power of the idle second charging modules is determined as the second charging power; it is determined whether the second charging power is less than the first remaining power. If the second charging power is less than the first remaining power, the idle second charging modules are determined as part of the target charging modules, and another part of the target charging modules is determined from the third and / or fourth charging modules corresponding to the charging gun based on the first remaining power and the second charging power; if the second charging power is greater than or equal to the first remaining power, when the idle second charging module is less than the target charging power, the target charging module is selected from the third and / or fourth charging modules corresponding to the charging gun. When the number of idle second charging modules is equal to one, the idle second charging module is designated as the target charging module. When the number of idle second charging modules is greater than one, the utilization rate of each second charging module is determined sequentially based on the total output power and total charging time of each second charging module. Then, based on the utilization rate of each second charging module and the first remaining power, the target charging module is determined from the idle second charging modules. Based on the first remaining power, the target charging module is determined from the third and / or fourth charging modules corresponding to the charging gun. If there are no idle second charging modules among the second charging modules, the target charging module is determined from the third and / or fourth charging modules corresponding to the charging gun based on the first remaining power. In this way, based on the target charging power, when the charging power provided by the first charging module is insufficient, the remaining charging modules are prioritized to supply power to the charging gun, improving the charging efficiency of the charging device. Furthermore, under the same priority, by determining the utilization rate of multiple charging modules, the charging module with the lower utilization rate is prioritized to supply power to the charging gun, so that the lifespan of each charging module of the charging device is balanced.
