Description

Technical Field

[0001] The embodiments of the present application relate to the field of charging technology, and in particular to a charging method, a charging pile, and a charging system. Background Art

[0002] The charging system includes a charging gun and a charging pile. After the charging gun is plugged into the charging device (such as an electric car), the charging pile can charge the charging device through the charging gun.

[0003] The charging pile includes multiple charging modules. In related technologies, after the charging system selects a target charging module from the multiple charging modules, it can directly charge the charging device through the charging gun based on the target charging module.

[0004] However, the method in the related art is a method of charging the charging device directly based on the target charging module through the charging gun, which may cause the charging device to malfunction. Therefore, the method in the related art has the problem of low charging safety. Summary of the Invention

[0005] The embodiments of the present application provide a charging method, a charging pile, and a charging system, which improve charging safety.

[0006] In a first aspect, embodiments of the present application provide a charging method, which is applied to a charging system, wherein the charging system includes multiple charging groups and multiple charging guns; the charging groups include multiple charging modules, and each charging gun has a first charging module corresponding to the charging module; the charging gun is connected to any charging module in any charging group; the method includes:

[0007] Obtaining a charging request corresponding to the first charging gun; the charging request includes a power requirement value of the first charging device;

[0008] Determining, based on the power demand value, at least one target charging module from the charging modules of the multiple charging groups; the at least one target charging module includes a target first charging module, which is a first charging module corresponding to the first charging gun;

[0009] When the charging state of the target first charging module is in the use state, controlling the target first charging module to stop charging the second charging device through the second charging gun; the first charging gun and the second charging gun are different;

[0010] Control at least one target charging module to charge the first charging device through the first charging gun.

[0011] In this solution, the charging system can obtain a charging request corresponding to the first charging gun; the charging request includes the power requirement value of the first charging device. The charging system can determine at least one target charging module from the charging modules of multiple charging groups based on the power requirement value; the at least one target charging module includes a target first charging module, and the target first charging module is the first charging module corresponding to the first charging gun. When the charging status of the target first charging module is in use, the charging system can control the target first charging module to stop charging the second charging device through the second charging gun (the second charging gun is different from the first charging gun), and control at least one target charging module to charge the first charging device through the first charging gun. In this way, it is possible to avoid the target first charging module charging the first charging device and the second charging device at the same time, resulting in a short circuit between the first charging device and the second charging device, thereby causing failure of the first charging device and the second charging device, thereby improving charging safety.

[0012] In one implementation,

[0013] For any first charging group, the (i+j)th charging module in the first charging group, excluding the (i)th charging module, is connected to the (i)th charging module via the first switches corresponding to the (i+j)th charging module and the (i)th charging module; i is an integer between 1 and N, j is an integer between 1 and Ni, and N is the number of charging modules in the charging group;

[0014] A first charging module in a first charging group is connected to a first charging module in a second charging group via a second switch corresponding to the first charging module; first charging modules in different charging groups correspond to the same second switch; and the second charging group is a charging group other than the first charging group among the multiple charging groups;

[0015] A first charging module in the first charging group is connected to a charging gun corresponding to the first charging module.

[0016] In this solution, for any first charging group, the i+jth charging module in the first charging group, excluding the ith charging module, is connected to the ith charging module via the first switches corresponding to the i+jth charging module and the ith charging module; i is an integer between 1 and N, j is an integer between 1 and Ni, and N is the number of charging modules included in the charging group. A first charging module in the first charging group is connected to a first charging module in the second charging group via the second switch corresponding to the first charging module; first charging modules in different charging groups correspond to the same second switch; the second charging group is a charging group other than the first charging group among the multiple charging groups. A first charging module in the first charging group is connected to the charging gun corresponding to the first charging module. Compared to the full matrix topology in the related art, which requires the deployment of a large number of switches, the structure of the embodiment of the present application further reduces the number of switches while ensuring the performance of the charging system, thereby reducing the hardware cost of the charging system and improving the reliability of the charging system.

[0017] In one implementation, controlling the target first charging module to stop charging the second charging device through the second charging gun includes:

[0018] Determining whether a target first switch exists among at least one first switch corresponding to the target first charging module; wherein the target first switch is a first switch in a closed state;

[0019] In the case that the target first switch exists, the target first switch is controlled to switch from a closed state to an open state, so that the target first charging module stops charging the second charging device through the second charging gun.

[0020] In this solution, the charging system can determine whether a target first switch exists among the at least one first switch corresponding to the target first charging module; the target first switch is a first switch in the closed state. If the target first switch exists, the charging system can control the target first switch to switch from the closed state to the open state, so that the target first charging module stops charging the second charging device via the second charging gun. This approach can prevent the target first charging module from charging the first and second charging devices simultaneously, causing a short circuit between the first and second charging devices, and thus leading to failure of the first and second charging devices, thereby improving charging safety.

[0021] In one implementation, controlling the target first charging module to stop charging the second charging device through the second charging gun includes:

[0022] Determining whether the second switch corresponding to the target first charging module is in a closed state;

[0023] When the second switch corresponding to the target first charging module is in a closed state, the second switch corresponding to the target first charging module is controlled to switch from a closed state to an open state, so that the target first charging module stops charging the second charging device through the second charging gun.

[0024] In this solution, the charging system can determine whether the second switch corresponding to the target first charging module is in a closed state. When the second switch corresponding to the target first charging module is in a closed state, the charging system can control the second switch corresponding to the target first charging module to switch from a closed state to an open state, so that the target first charging module stops charging the second charging device through the second charging gun. This method can prevent the target first charging module from charging the first charging device and the second charging device at the same time, causing a short circuit between the first charging device and the second charging device, thereby improving charging safety.

[0025] In one implementation, the method further includes:

[0026] The charging state of the target first charging module is updated from the use state to the idle state.

[0027] In this solution, after controlling the target first charging module to stop charging the second charging device through the second charging gun, the charging system can also update the charging status of the target first charging module from the use status to the idle status so that the charging status of the target first charging module matches the actual status.

[0028] In one implementation, determining at least one target charging module from charging modules of a plurality of charging groups according to the power demand value includes:

[0029] Determining a target first charging module from charging modules in a plurality of charging groups;

[0030] Obtaining a power value of a target first charging module;

[0031] Determining whether the power value of the target first charging module is greater than or equal to the power requirement value;

[0032] When the power value of the target first charging module is greater than or equal to the power requirement value, determining that the at least one target charging module includes the target first charging module;

[0033] When the power value of the target first charging module is less than the power requirement value, at least one target second charging module is determined from the charging modules in the multiple charging groups based on the power requirement value, the power value of the target first charging module, the charging status of the charging modules of each charging group, and the power value of the charging modules of each charging group, and it is determined that the at least one target charging module includes the target first charging module and at least one target second charging module; the charging status is an idle state or a use state.

[0034] In this solution, the charging system can obtain the power value of the target first charging module. When the power value of the target first charging module is greater than or equal to the power requirement value, the charging system can determine that at least one target charging module includes the target first charging module. When the power value of the target first charging module is less than the power requirement value, the charging system can determine at least one target second charging module from the charging modules in the multiple charging groups based on the power requirement value, the power value of the target first charging module, the charging status of the charging modules of each charging group, and the power value of the charging modules of each charging group, and determine that the at least one target charging module includes the target first charging module and at least one target second charging module. In this way, when the power value of the target first charging module cannot meet the charging requirement of the first charging device, the target first charging module and the target second charging module can be controlled as the target charging modules, and the first charging device can be powered by the first charging gun, thereby meeting the charging requirement of the first charging device and improving the power supply efficiency and stability of the charging system.

[0035] In one implementation, determining at least one target second charging module from the charging modules in the plurality of charging groups based on the power demand value, the power value of the target first charging module, the charging status of the charging modules in each charging group, and the power values of the charging modules in each charging group includes:

[0036] Determining a first power difference according to a power value and a power requirement value of the target first charging module;

[0037] Determine, based on the charging status of the charging modules of each charging group, whether there is at least one idle charging module in a first target charging group other than the target first charging module; the first target charging group is the charging group to which the target first charging module belongs;

[0038] When there is at least one idle charging module in the first target charging group in addition to the target first charging module, at least one target second charging module is determined from the at least one idle charging module in the first target charging group based on the first power difference and the power value of the at least one idle charging module in the first target charging group.

[0039] In this solution, in the process of determining at least one target second charging module from the charging modules in multiple charging groups, the charging system can determine a first power difference based on the power value and power demand value of the target first charging module. The charging system can determine whether there is at least one idle charging module in the first target charging group other than the target first charging module based on the charging status of the charging modules in each charging group; the first target charging group is the charging group to which the target first charging module belongs. In the case where there is at least one idle charging module in the first target charging group other than the target first charging module, the charging system can determine at least one target second charging module from the at least one idle charging module in the first target charging group based on the first power difference and the power value of the at least one idle charging module in the first target charging group. In this way, at least one target second charging module can be quickly determined in the first target charging group to which the target first charging module belongs, thereby improving the efficiency of selecting the target charging module.

[0040] In one implementation, the method further includes:

[0041] When there is at least one idle charging module in the first target charging group other than the target first charging module, determining the total power value according to the power values of the idle charging modules in the first target charging group other than the target first charging module;

[0042] When the total power value is less than the first power difference value, determining the difference between the first power difference value and the total power value as the second power difference value;

[0043] Determining a second target charging group from the plurality of charging groups according to the charging status of the charging modules of each charging group; wherein the second target charging group is a charging group having charging modules in an idle state;

[0044] At least one target second charging module is determined from the idle charging modules in the second target charging group according to the second power difference and the power values of the idle charging modules in the second target charging group.

[0045] In this solution, when there is at least one idle charging module in the first target charging group in addition to the target first charging module, the charging system can determine the total power value based on the power values of the idle charging modules in the first target charging group in addition to the target first charging module. When the total power value is less than the first power difference, the charging system can determine the difference between the first power difference and the total power value as the second power difference. The charging system can determine a second target charging group from multiple charging groups based on the charging status of the charging modules in each charging group; wherein the second target charging group is a charging group with idle charging modules. The charging system can determine at least one target second charging module from the idle charging modules in the second target charging group based on the second power difference and the power values of the idle charging modules in the second target charging group. In this way, at least one target second charging module can be quickly determined in the second target charging group, thereby improving the efficiency of selecting the target charging module.

[0046] In one implementation, the method further includes:

[0047] When there is no idle charging module in the first target charging group other than the target first charging module, determining a second target charging group from the plurality of charging groups based on the charging states of the charging modules in each charging group; wherein the second target charging group is a charging group having idle charging modules;

[0048] At least one target second charging module is determined from the idle charging modules in the second target charging group according to the first power difference and the power values of the idle charging modules in the second target charging group.

[0049] In this solution, when there are no idle charging modules in the first target charging group other than the target first charging module, the charging system can determine a second target charging group from multiple charging groups based on the charging status of the charging modules of each charging group; wherein the second target charging group is a charging group with idle charging modules. The charging system can determine at least one target second charging module from the idle charging modules in the second target charging group based on the first power difference and the power value of the idle charging modules in the second target charging group. In this way, when the first target charging group cannot meet the charging needs of the first charging device, at least one target second charging module can be quickly determined from the second target charging group, so that the target first charging module and at least one target second charging module can power the first charging device through the first charging gun, thereby meeting the charging needs of the first charging device and improving the power supply efficiency and stability of the charging system.

[0156] First, the charging scenarios to which the embodiments of the present application are applicable are described.

[0157] Figure 1 A schematic diagram of a charging scenario provided in an embodiment of the present application.

[0158] like Figure 1 As shown, the charging scenario includes a power supply 10, a charging system 20, and a plurality of charging devices, wherein the plurality of charging devices include a first charging device 30 and a second charging device 40.

[0159] When the first charging device 30 needs to be charged, the charging system 20 may convert the AC power provided by the power supply 10 into DC power that can be used by the first charging device 30 to power the first charging device 30 .

[0160] When the second charging device 40 needs to be charged, the charging system 20 may convert the AC power provided by the power supply 10 into DC power that can be used by the second charging device 40 to power the second charging device 40 .

[0161] Below, the charging system provided in the embodiment of the present application is described.

[0162] Figure 2 A schematic diagram of the structure of a charging system provided in an embodiment of the present application Figure 1 .

[0163] like Figure 2 As shown, the charging system 20 may include multiple charging groups (also referred to as power pools) and multiple charging guns. In one implementation, the charging system may include a power distribution unit (PDU) 201, which may include a controller ( Figure 2 not shown).

[0164] The charging group includes multiple charging modules. Among the charging modules of the multiple charging groups, there is a first charging module corresponding to each charging gun. It is understandable that each charging gun can correspond to a first charging module.

[0165] The charging gun can be connected to any charging module in any charging group.

[0166] For example, Figure 2 Two charging groups are shown, namely charging group 1 and charging group 2. Figure 2 Six charging guns are shown, namely, charging gun 1, charging gun 2, ..., and charging gun 6. Charging group 1 includes three charging modules, namely, charging module 1, charging module 2, and charging gun 3. Charging group 2 includes three charging modules, namely, charging module 4, charging module 5, and charging module 6.

[0167] Next, the connection of multiple charging modules in the charging group is described.

[0168] For any first charging group, the i+jth charging module in the first charging group, excluding the i-th charging module, is connected to the i-th charging module via the first switches corresponding to the i+jth charging module and the i-th charging module. It is understood that the first switch belongs to the charging system 20, and further, the first switch belongs to the first charging group. It is understood that in the first charging group, every two charging modules are connected via a first switch. It should also be noted that the opening and closing of each first switch is controlled by the control unit in the power distribution unit 201. In other words, the controller controls each first switch to switch from a closed state to an open state, or from an open state to a closed state.

[0169] It should be noted that i is an integer between 1 and N, j is an integer between 1 and Ni, and N is the number of charging modules included in the charging group.

[0170] In one implementation:

[0171] The charging system 20 includes connection lines corresponding to each charging module, including a first line.

[0172] The (i+j)th charging module other than the (i)th charging module in the first charging group is connected to the (i)th charging module via the first line corresponding to the (i+j)th charging module, the first switch corresponding to the (i+j)th charging module and the (i)th charging module, and the first line corresponding to the (i)th charging module.

[0173] In one implementation:

[0174] The charging system 20 includes a connection line corresponding to each charging module. The connection line includes a first line, a second line and a third switch. For example, Figure 3 This is a schematic diagram of a connection circuit provided in an embodiment of the present application. Figure 3 As shown, one end of the first circuit is connected to the charging module, one end of the third switch is set on the first circuit, and the other end of the third switch is set on the second circuit. It should be noted that the third switch is in a closed state.

[0175] The (i+j)th charging module other than the (i)th charging module in the first charging group is connected to the (i)th charging module via the first line corresponding to the (i+j)th charging module, the first switch corresponding to the (i+j)th charging module and the (i)th charging module, the second line corresponding to the (i)th charging module, the third switch corresponding to the (i)th charging module, and the first line corresponding to the (i)th charging module.

[0176] Next, combine Figure 2 , an exemplary description is given of the connection status of multiple charging modules in the charging group.

[0177] like Figure 2 As shown, in charging group 1:

[0178] The first charging module in charging group 1 is charging module 1, the second charging module in charging group 1 is charging module 2, and the third charging module in charging group 1 is charging module 3.

[0179] The charging module 2 is connected to the charging module 1 through the first line A2 corresponding to the charging module 2, the first switch S12 corresponding to the charging module 1 and the charging module 2, the second line B1 corresponding to the charging module 1, the third switch S1 corresponding to the charging module 1, and the first line A1 corresponding to the charging module 1.

[0180] The charging module 3 is connected to the charging module 1 through the first line A3 corresponding to the charging module 3, the first switch S13 corresponding to the charging module 1 and the charging module 3, the second line B1 corresponding to the charging module 1, the third switch S1 corresponding to the charging module 1, and the first line A1 corresponding to the charging module 1.

[0181] The charging module 3 is connected to the charging module 2 through the first line A3 corresponding to the charging module 3, the first switch S23 corresponding to the charging module 2 and the charging module 3, the second line B2 corresponding to the charging module 2, the third switch S2 corresponding to the charging module 2, and the first line A2 corresponding to the charging module 2.

[0182] In Charge Group 2:

[0183] The first charging module in the charging group 2 is charging module 4 , the second charging module in the charging group 2 is charging module 5 , and the third charging module in the charging group 2 is charging module 6 .

[0184] The charging module 5 is connected to the charging module 4 through the first line A5 corresponding to the charging module 5, the first switch S45 corresponding to the charging module 4 and the charging module 5, the second line B4 corresponding to the charging module 4, the third switch S4 corresponding to the charging module 4, and the first line A4 corresponding to the charging module 4.

[0185] The charging module 6 is connected to the charging module 4 through the first line A6 corresponding to the charging module 6, the first switch S46 corresponding to the charging module 4 and the charging module 6, the second line B4 corresponding to the charging module 4, the third switch S4 corresponding to the charging module 4, and the first line A4 corresponding to the charging module 4.

[0186] The charging module 6 is connected to the charging module 5 through the first line A6 corresponding to the charging module 6, the first switch S56 corresponding to the charging module 5 and the charging module 6, the second line B5 corresponding to the charging module 5, the third switch S5 corresponding to the charging module 5, and the first line A5 corresponding to the charging module 5.

[0187] In addition, if Figure 2 As shown, one end of the third switch S3 corresponding to the charging module 3 is set on the first line A3 corresponding to the charging module 3; the other end of the third switch S3 corresponding to the charging module 3 is set on the second line B3 corresponding to the charging module 3. One end of the third switch S6 corresponding to the charging module 6 is set on the first line A6 corresponding to the charging module 6; the other end of the third switch S6 corresponding to the charging module 6 is set on the second line B6 corresponding to the charging module 6.

[0188] In addition, a first charging module in the first charging group is connected to a first charging module in the second charging group via a second switch corresponding to the first charging module. In one implementation, the second switch corresponding to each first charging module belongs to the power distribution unit 201. It should also be noted that the control unit in the power distribution unit 201 controls the opening and closing of each second switch. In other words, the controller controls each second switch to switch from a closed state to an open state, or from an open state to a closed state.

[0189] It should be noted that one first charging module of different charging groups corresponds to the same second switch. The second charging group is a charging group other than the first charging group among the multiple charging groups.

[0190] In one implementation, the first charging module in the first charging group is connected to the first charging module in the second charging group through the first line and the third line corresponding to the first charging module, the second switch corresponding to the first charging module, and the first line and the third line corresponding to a first charging module in the second charging group.

[0191] For example, take charging group 1 as the first charging group and charging group 2 as the second charging group. Figure 2 As shown:

[0192] Charging module 1 in charging group 1 (charging module 1 is a first charging module) is connected to charging module 4 in charging group 2 via first line A1 and third line C1 corresponding to charging module 1, second switch S14 corresponding to charging module 1 (the second switch corresponding to charging module 1 and charging module 4), and first line A4 and third line C4 corresponding to charging module 4 in charging group 2 (charging module 4 is a first charging module). Charging module 1 in charging group 1 and charging module 4 in charging group 2 are connected to the same second switch, second switch S14.

[0193] Similarly, charging module 2 in charging group 2 (charging module 2 is a first charging module) is connected to charging module 5 in charging group 2 through the first line A2 and the third line C2 corresponding to charging module 2, the second switch S25 corresponding to charging module 2 (the second switch corresponding to charging module 2 and charging module 5), and the first line A5 and the third line C5 corresponding to charging module 5 in charging group 2 (charging module 5 is a first charging module).

[0194] Charging module 3 in charging group 2 (charging module 3 is a first charging module) is connected to charging module 6 in charging group 2 through the first line A3 and the third line C3 corresponding to charging module 3, the second switch S36 corresponding to charging module 3 (the second switch corresponding to charging module 3 and charging module 6), and the first line A6 and the third line C6 corresponding to charging module 6 in charging group 2 (charging module 6 is a first charging module).

[0195] In addition, a first charging module in the first charging group is connected to the charging gun corresponding to the first charging module. In one implementation, one end of the first circuit corresponding to the first charging module is connected to the first charging module; the other end of the first circuit corresponding to the first charging module is connected to one end of the third circuit corresponding to the first charging module; and the other end of the third circuit corresponding to the first charging module is connected to the charging gun corresponding to the first charging module. It should be noted that the third circuit corresponding to each first charging module and the second switch corresponding to each first charging module belong to the power distribution unit 201.

[0196] In one implementation:

[0197] Each charging module of each charging group is a first charging module corresponding to a charging gun. In other words, each charging module corresponds to a charging gun.

[0198] For example, Figure 2 As shown, the three charging modules (charging module 1, charging module 2, charging module 3) included in the charging group 1 are all first charging modules; the three charging modules (charging module 4, charging module 5, charging module 6) included in the charging group 2 are all first charging modules.

[0199] The charging module 1 in the charging group 1 is connected to the charging gun 1 corresponding to the charging module 1 .

[0200] The charging module 2 in the charging group 1 is connected to the charging gun 2 corresponding to the charging module 2 .

[0201] The charging module 3 in the charging group 1 is connected to the charging gun 3 corresponding to the charging module 3 .

[0202] The charging module 4 in the charging group 2 is connected to the charging gun 4 corresponding to the charging module 4 .

[0203] The charging module 5 in the charging group 2 is connected to the charging gun 5 corresponding to the charging module 5 .

[0204] The charging module 6 in the charging group 2 is connected to the charging gun 6 corresponding to the charging module 6 .

[0205] In one implementation:

[0206] In each charging group, there is a charging module that does not correspond to a charging gun. In other words, in each charging group, there is at least one charging module that is not the first charging module.

[0207] For example, Figure 4 A schematic diagram of the structure of a charging system provided in an embodiment of the present application Figure 2 .

[0208] like Figure 4 As shown, the three charging modules included in charging group 1 are charging module 1, charging module 2, and charging module 3. Among them, charging module 1 and charging module 2 are both first charging modules, and charging module 3 is not a first charging module. The three charging modules included in charging group 2 are charging module 4, charging module 5, and charging module 6. Among them, charging module 4 and charging module 5 are both first charging modules, and charging module 6 is not a first charging module.

[0209] The charging module 1 in the charging group 1 is connected to the charging gun 1 corresponding to the charging module 1. Figure 4 As shown, one end of the first line A1 corresponding to the charging module 1 is connected to the charging module 1; the other end of the first line A1 corresponding to the charging module 1 is connected to one end of the third line C1 corresponding to the charging module 1; the other end of the third line C1 corresponding to the charging module 1 is connected to the charging gun 1 corresponding to the charging module 1.

[0210] The charging module 2 in the charging group 1 is connected to the charging gun 2 corresponding to the charging module 2. Figure 4 As shown, one end of the first line A2 corresponding to the charging module 2 is connected to the charging module 2; the other end of the first line A2 corresponding to the charging module 2 is connected to one end of the third line C2 corresponding to the charging module 2; the other end of the third line C2 corresponding to the charging module 2 is connected to the charging gun 2 corresponding to the charging module 2.

[0211] The charging module 4 in the charging group 2 is connected to the charging gun 4 corresponding to the charging module 4. Figure 4As shown, one end of the first line A4 corresponding to the charging module 4 is connected to the charging module 4; the other end of the first line A4 corresponding to the charging module 4 is connected to one end of the third line C4 corresponding to the charging module 4; the other end of the third line C4 corresponding to the charging module 4 is connected to the charging gun 4 corresponding to the charging module 4.

[0212] The charging module 5 in the charging group 2 is connected to the charging gun 5 corresponding to the charging module 5. Figure 4 As shown, one end of the first line A5 corresponding to the charging module 5 is connected to the charging module 5; the other end of the first line A5 corresponding to the charging module 5 is connected to one end of the third line C5 corresponding to the charging module 5; the other end of the third line C5 corresponding to the charging module 5 is connected to the charging gun 5 corresponding to the charging module 5.

[0213] One end of the first line A3 corresponding to the charging module 3 is connected to the charging module 3. The power distribution unit 201 does not include a third line corresponding to the charging module 3. In other words, the other end of the first line A3 corresponding to the charging module 3 is not connected to a third line, and further, is not connected to a charging gun via a third line.

[0214] One end of the first line A6 corresponding to the charging module 6 is connected to the charging module 6. The power distribution unit 201 does not include a third line corresponding to the charging module 6. In other words, the other end of the first line A6 corresponding to the charging module 6 is not connected to a third line, and thus is not connected to the charging gun through a third line.

[0215] Next, the charging module and charging gun in the charging system are described.

[0216] Charging module: Also known as a power conversion module, it is used to convert the AC power provided by the power supply into DC power that can be used by the charging device.

[0217] Charging gun: Used to transmit the DC power output by the charging module to the charging device to charge the charging device connected to the charging gun. It should be noted that the charging gun can be a liquid-cooled charging gun, an air-cooled charging gun, or other types of charging guns, and this embodiment of the application is not limited to this.

[0218] Controller: This can be a microcontroller unit (MCU) or other device with control capabilities. An MCU, also known as a single-chip microcomputer or microcontroller, is a chip-level computer that reduces the frequency and specifications of a central processing unit (CPU) and integrates various components onto a single chip. This allows for different control combinations for different applications.

[0219] The following is a detailed description of the charging method of the embodiment of the present application. It should be noted that the following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. It should also be noted that the execution subject of the following embodiments is the charging system, more specifically, the controller in the charging system. Among them, the controller belongs to the power distribution unit in the charging system.

[0220] Figure 5 A schematic diagram of a charging method provided in an embodiment of the present application Figure 1 See also Figure 5 , the method specifically comprises the following steps:

[0221] S501: Obtain a charging request from a first charging gun.

[0222] In this embodiment, the first charging gun may generate a charging request when detecting that the first charging device is connected to the first charging gun.

[0223] The charging request may include a power requirement value of the first charging device. For example, the power requirement value of the first charging device may be 80KW.

[0224] S502: Determine at least one target charging module from the charging modules in the plurality of charging groups according to the power demand value.

[0225] In this embodiment, the charging system may determine at least one target charging module from the charging modules in the plurality of charging groups according to the power requirement value.

[0226] Wherein, the at least one target charging module includes a target first charging module.

[0227] It should be noted that the target first charging module is the first charging module corresponding to the first charging gun. It can be understood that one end of the first circuit corresponding to the target first charging module is connected to the target first charging module; the other end of the first circuit corresponding to the target first charging module is connected to one end of the third circuit corresponding to the target first charging module; and the other end of the third circuit corresponding to the target first charging module is connected to the first charging gun.

[0228] S503: When the charging state of the target first charging module is in use state, control the target first charging module to stop charging the second charging device through the second charging gun.

[0229] In this embodiment, the charging system can record the charging status of each charging module, wherein the charging status can be an idle state or an in-use state.

[0230] The charging system may determine whether the charging status of the target first charging module is in a use state.

[0231] If the charging state of the target first charging module is not in use, the charging system may execute S504;

[0232] When the charging state of the target first charging module is in use state, the charging system may control the target first charging module to stop charging the second charging device through the second charging gun.

[0233] Next, a process of controlling the first charging module of the charging system to stop charging the second charging device through the second charging gun will be described.

[0234] When the charging state of the target first charging module is the use state, the target first charging module supplies power to the second charging device through the second charging gun.

[0235] In one implementation, the first charging module corresponding to the second charging gun and the target first charging module belong to the same charging group. The target first charging module is connected to the first charging module corresponding to the second charging gun via a first switch (target first switch). The target first switch is in a closed state.

[0236] In one implementation, the first charging module corresponding to the second charging gun and the target first charging module do not belong to the same charging group. The target first charging module is connected to the first charging module corresponding to the second charging gun via the second switch corresponding to the target first charging module. The second switch corresponding to the target first charging module is in a closed state.

[0237] In one implementation, the first charging module corresponding to the second charging gun does not belong to the same charging group as the target first charging module. The first charging module corresponding to the second charging gun is connected to the intermediate first charging module through a first switch (target first switch). The target first switch is in a closed state. The intermediate first charging module and the first charging module corresponding to the second charging gun belong to the same charging group. The target first charging module is connected to the intermediate first charging module through the second switch corresponding to the target first charging module. The second switch corresponds to both the target first charging module and the intermediate first charging module, and the second switch is in a closed state.

[0238] In one implementation, the first charging module corresponding to the second charging gun does not belong to the same charging group as the target first charging module. The target first charging module is connected to the intermediate first charging module through a first switch (target first switch). The target first switch is in a closed state. The intermediate first charging module and the target first charging module belong to the same charging group. The intermediate first charging module is connected to the first charging module corresponding to the second charging gun through the second switch corresponding to the intermediate first charging module. The second switch corresponds to both the intermediate first charging module and the first charging module corresponding to the second charging gun, and the second switch is in a closed state.

[0239] Based on the above content, it can be seen that when the target first charging module charges the second charging device through the second charging gun, there is a target first switch (a first switch in a closed state) in at least one first switch corresponding to the target first charging module, or the second switch corresponding to the target first charging module is in a closed state.

[0240] Based on this, when it is necessary to control the target first charging module to stop charging the second charging device through the second charging gun:

[0241] In one implementation:

[0242] The charging system may determine whether a target first switch exists among at least one first switch corresponding to the target first charging module; wherein the target first switch is a first switch in a closed state.

[0243] In the case where the target first switch exists, the charging system can control the target first switch to switch from a closed state to an open state, so that the target first charging module stops charging the second charging device through the second charging gun.

[0244] In one implementation:

[0245] The charging system may determine whether the second switch corresponding to the target first charging module is in a closed state.

[0246] When the second switch corresponding to the target first charging module is in a closed state, the charging system can control the second switch corresponding to the target first charging module to switch from a closed state to an open state, so that the target first charging module stops charging the second charging device through the second charging gun.

[0247] In addition, in one implementation, the charging system may also update the charging state of the target first charging module from the use state to the idle state.

[0248] S504: Control at least one target charging module to charge the first charging device through the first charging gun.

[0249] In this embodiment, the charging system may control at least one target charging module to charge the first charging device through the first charging gun.

[0250] In addition, in one implementation, when the charging system controls at least one target charging module to charge the first charging device through the first charging gun, the charging state of the at least one target charging module can be updated from an idle state to a used state.

[0251] Beneficial effects of this embodiment: In this embodiment, the charging system can obtain a charging request corresponding to the first charging gun; the charging request includes the power requirement value of the first charging device. The charging system can determine at least one target charging module from the charging modules of multiple charging groups based on the power requirement value; the at least one target charging module includes a target first charging module, and the target first charging module is the first charging module corresponding to the first charging gun. When the charging status of the target first charging module is in the use state, the charging system can control the target first charging module to stop charging the second charging device through the second charging gun, and control at least one target charging module to charge the first charging device through the first charging gun. In this way, it is possible to avoid the target first charging module charging the first charging device and the second charging device at the same time, resulting in a short circuit between the first charging device and the second charging device, thereby causing failure of the first charging device and the second charging device, thereby improving charging safety.

[0252] Figure 6 A schematic diagram of a charging method provided in an embodiment of the present application Figure 2 See also Figure 6 , the method specifically comprises the following steps:

[0253] S601: Obtain a charging request from a first charging gun.

[0254] In this embodiment, the charging system may obtain a charging request from the first charging gun, where the charging request includes a power requirement value of the first charging device.

[0255] S602: Determine a target first charging module from charging modules in multiple charging groups.

[0256] In this embodiment, the charging system may record the first charging module corresponding to each charging gun.

[0257] It should be noted that the first charging module corresponding to the charging gun refers to the charging module directly connected to the charging gun. It can be understood that one end of the first circuit corresponding to the first charging module is connected to the first charging module; the other end of the first circuit corresponding to the first charging module is connected to one end of the third circuit corresponding to the first charging module; and the other end of the third circuit corresponding to the first charging module is connected to the charging gun.

[0258] The charging system may determine a first charging module corresponding to the first charging gun, ie, a target first charging module, from the charging modules in the multiple charging groups.

[0259] S603: Acquire the power value of the target first charging module.

[0260] In this embodiment, the charging system can record the power value of each charging module.

[0261] After determining the target first charging module, the charging system may obtain the power value of the target first charging module.

[0262] S604: Determine whether the power value of the target first charging module is greater than or equal to the power requirement value.

[0263] In this embodiment, the charging system may determine whether the power value of the target first charging module is greater than or equal to the power requirement value.

[0264] If the power value of the target first charging module is greater than or equal to the power requirement value, the charging system may execute S605;

[0265] When the target power value of the first charging module is less than the power requirement value, the charging system may execute S606 .

[0266] S605: Determine that at least one target charging module includes a target first charging module.

[0267] In this embodiment, when the power value of the target first charging module is greater than or equal to the power requirement value, the charging system may determine that the at least one target charging module includes the target first charging module.

[0268] It should be noted that, after executing S605 , the charging system executes S608 .

[0269] S606: Determine at least one target second charging module from the charging modules in the multiple charging groups according to the power demand value, the power value of the target first charging module, the charging status of the charging modules in each charging group, and the power value of the charging modules in each charging group.

[0270] In this embodiment, when the power value of the target first charging module is less than the power requirement value, the charging system can determine at least one target second charging module from the charging modules in multiple charging groups based on the power requirement value, the power value of the target first charging module, the charging status of the charging modules of each charging group, and the power value of the charging modules of each charging group.

[0271] The following describes a process by which the charging system determines at least one target second charging module from the charging modules in multiple charging groups based on a power demand value, a power value of a target first charging module, a charging state of the charging modules in each charging group, and a power value of the charging modules in each charging group.

[0272] In one implementation:

[0273] The charging system may determine a first power difference value based on the power value and the power requirement value of the target first charging module, wherein the first power difference value is the difference between the power requirement value and the power value of the target first charging module.

[0274] The charging system can determine whether there is at least one idle charging module in the first target charging group other than the target first charging module based on the charging status of the charging modules in each charging group. It should be noted that the first target charging group is the charging group to which the target first charging module belongs.

[0275] When there is at least one idle charging module in the first target charging group in addition to the target first charging module, the charging system can determine at least one target second charging module from the at least one idle charging module in the first target charging group based on the first power difference and the power value of the at least one idle charging module in the first target charging group.

[0276] If no idle charging modules exist in the first target charging group other than the target first charging module, the charging system may determine a second target charging group from the multiple charging groups based on the charging states of the charging modules in each charging group; wherein the second target charging group is a charging group in the multiple charging groups that has idle charging modules. The charging system may determine at least one target second charging module from the idle charging modules in the second target charging group based on the first power difference and the power values of the idle charging modules in the second target charging group.

[0277] S607: Determine that the at least one target charging module includes a target first charging module and at least one target second charging module.

[0278] In this embodiment, after determining at least one target second charging module, the charging system may determine that the at least one target charging module includes a target first charging module and at least one target second charging module.

[0279] It should be noted that the charging system executes S608 after executing S607.

[0280] S608: When the charging state of the target first charging module is in use, control the target first charging module to stop charging the second charging device through the second charging gun.

[0281] In this embodiment, the charging system may control the target first charging module to stop charging the second charging device through the second charging gun when the charging state of the target first charging module is in the use state.

[0282] The specific implementation process is the same as S503 and will not be repeated here.

[0283] S609: Control at least one target charging module to charge the first charging device through the first charging gun.

[0284] In this embodiment, the charging system may control at least one target charging module to charge the first charging device through the first charging gun.
