[0088] The above drawings have shown clear embodiments of the present application, which will be described in more detail later. These drawings and text descriptions are not intended to limit the scope of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0089] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0090] In the related art, power scheduling between charging devices in a charging station is implemented through a power controller, and the control of power scheduling is concentrated in the power controller of the charging station. If the power controller fails, all charging devices in the charging station cannot perform power scheduling.

[0091] In view of this, the present application proposes a power dispatching method for a charging station, which is applied to any charging device in the charging station. When the charging device determines that the preset available power is greater than the output required power, the charging device can control at least part of the remaining power of the charging device to be dispatched to other charging devices in the charging station that need to borrow power. In the method of the embodiment of the present application, the charging device can control the power dispatching between charging devices to realize the distributed control of power dispatching. Compared with the method in the related art that the failure of the power control unit will affect the inability of all charging devices in the charging station to perform power dispatching, in the method of the embodiment of the present application, in the case of a failure of any charging device, the functions of other charging devices in the charging station can still be dispatched.

[0092] It should be understood that the power scheduling method of the charging station in the embodiment of the present application can be used in any power scheduling scenario. The execution subject of the embodiment of the present application can be any charging device in the charging station, and the charging device is not limited to a specific implementation method and can be implemented by software and / or hardware. Specifically, the charging device can be, for example, an electronic device or a processor.

[0093] The technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems are described in detail below with specific embodiments. 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. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0094] Figure 1 A schematic diagram of a power dispatching method for a charging station provided in an embodiment of the present application Figure 1 . A first charging device used in a charging station, such as Figure 1 As shown in , the power scheduling method of the charging station may include the following steps:

[0095] S101 : Determine a first preset available power and a first required output power of a first charging device.

[0096] The first charging device is any charging device in the charging station.

[0097] The first preset available power is a preset power that the first charging device obtains electric power from the transformer of the charging station.

[0098] The first output required power is the sum of the power required by the first charging device to charge the electrical equipment and the power dispatched by the first charging device to other charging devices other than the second charging device.

[0099] Determine the first preset available power of the first charging device. For example, the rated power of the switch on the single-phase power line to which the first charging device is connected can be determined, and the first preset available power can be set in advance for each charging device on the single-phase power line. The first preset available power of each charging device can be equal or unequal, and the condition that the sum of the first preset available power of each charging device is less than or equal to the rated power of the switch on the single-phase power line is satisfied. Furthermore, the first preset available power of each charging device can be pre-stored in any storage space of each charging device. When determining the first preset available power of the first charging device, the first charging device can read the first preset available power from the storage space of the first charging device.

[0100] In the case where the first charging device does not dispatch power supply to other charging devices, the first output required power of the first charging device is determined, and the power required power of the power-consuming device connected to the first charging device can be obtained, and the power required power of the power-consuming device is determined as the first output required power of the first charging device. For example, the rated output power of the first charging device can be obtained and determined as the first output required power of the first charging device.

[0101] In the case that the first charging device has power scheduled for other charging devices, the first output required power of the first charging device is determined. The power required by the electrical equipment connected to the first charging device and the sum of the power scheduled by the first charging device to other charging devices other than the second charging device can be obtained, and the sum of the powers is determined as the first output required power of the first charging device.

[0102] S102: When the first preset available power is greater than the first output required power, dispatch at least part of the remaining power of the first charging device to a second charging device in the charging station.

[0103] The magnitude of the remaining power is the difference between the first preset power and the first output required power. The remaining power is the power that the first charging device can dispatch for the second charging device.

[0104] The second output power requirement of the second charging device is greater than the actual available power of the second charging device. The second charging device is a charging device in the charging station that is connected to the same phase power line as the first charging device. The second output power requirement of the second charging device is greater than the actual available power of the second charging device, indicating that the current actual available power of the second charging device is insufficient to meet the second output power requirement for charging the charging device.

[0105] The actual available power is the sum of the second preset available power of the second charging device and the power borrowed by the second charging device. The power borrowed by the second charging device is the power dispatched to the second charging device by other charging devices other than the current second charging device.

[0106] The first preset available power is greater than the first output required power, indicating that the first charging device has surplus power that can be dispatched to the second charging device. In this case, the first charging device can dispatch at least part of the surplus power of the first charging device to the second charging device in the charging station. For example, the first charging device can receive the size of the power requested to be dispatched by the second charging device. When the size of the surplus power of the first charging device is greater than or equal to the size of the power requested to be dispatched by the second charging device, the size of the power requested to be dispatched by the second charging device is determined as the size of the power to be dispatched, and at least part of the surplus power of the first charging device is dispatched to the second charging device in the charging station. When the size of the surplus power of the first charging device is less than the size of the power requested to be dispatched by the second charging device, the size of the surplus power of the first charging device is determined as the size of the power to be dispatched, and all of the surplus power of the first charging device is dispatched to the second charging device in the charging station.

[0107] The power dispatching method of the charging station of the present application is applied to the first charging device in the charging station. The first charging device determines the first preset available power and the first output required power of the first charging device. When the first preset available power is greater than the first output required power, at least part of the remaining power of the first charging device is dispatched to the second charging device in the charging station, wherein the second output required power of the second charging device is greater than the actual available power of the second charging device. The method of the embodiment of the present application controls the power dispatching between charging devices by each charging device, thus realizing the distributed control of power dispatching. Compared with the method in the related art that the failure of the power control unit will affect the inability of all charging devices in the charging station to perform power dispatching, the method of the embodiment of the present application can still perform functional dispatching between other charging devices in the charging station when any charging device fails.

[0108] Figure 2 A schematic diagram of a power dispatching method for a charging station provided in an embodiment of the present application Figure 2 . The second charging device used in the charging station, such as Figure 2 As shown in , the power scheduling method of the charging station may include the following steps:

[0109] S201: Determine a second output required power and actual available power of a second charging device.

[0110] The second required output power of the second charging device is the power required by the second charging device to charge the electrical device.

[0111] The actual available power of the second charging device is the maximum power that the second charging device can output, and the actual available power of the second charging device is the sum of the second preset available power of the second charging device and the power that has been borrowed by the second charging device.

[0112] The second charging device determines the second output required power of the second charging device. For example, the second charging device can detect the power required power of the electrical equipment connected to the second charging device by a power detection method in related technology, and determine the power required power as the second output required power of the second charging device.

[0113] In the case that the second charging device does not borrow power, the actual available power of the second charging device is determined, and a second preset available power of the second charging device may be obtained, and the second preset available power may be determined as the actual available power of the second charging device.

[0114] In the case that the second charging device has borrowed power from other charging devices, the actual available power of the second charging device can be determined by obtaining the sum of the second preset available power of the second charging device and the power borrowed by the second charging device, and determining the sum of the powers as the actual available power of the second charging device.

[0115] S202 : When the second output required power is greater than the actual available power, borrow at least part of the remaining power of the first charging device from the first charging device in the charging station.

[0116] The actual available power is the sum of the second preset available power of the second charging device and the power borrowed by the second charging device. The power borrowed by the second charging device is the power dispatched to the second charging device by other charging devices other than the current second charging device.

[0117] The first preset available power of the first charging device is greater than the first output required power of the first charging device, and the remaining power of the first charging device is the difference between the first preset power and the first output required power.

[0118] The second output required power is greater than the actual available power, indicating that the power that the second charging device can currently output is less than the power required to charge the electrical device. In this case, the second charging device can borrow at least part of the remaining power of the first charging device from the first charging device in the charging station. For example, the second device can send the size of the power requested to be borrowed to the first charging device, and the first charging device can respond to the request and dispatch at least part of the remaining power of the first charging device to the second charging device.

[0119] In the related art, when a power control unit fails, all charging devices in the charging station are set to be unavailable to ensure electricity safety. In the method of the embodiment of the present application, when a first charging device fails, only the charging device connected to the same phase power line as the first charging device needs to be set to be unavailable to ensure electricity safety. Compared with the method in the related art where a power control unit failure affects all charging devices in the charging station, the impact scope of a single point failure on the charging station is reduced.

[0120] The power dispatching method of the charging station of the present application is applied to the second charging device in the charging station. The second charging device determines the second output demand power and the actual available power of the second charging device. When the second output demand power is greater than the actual available power, the second charging device borrows at least part of the remaining power of the first charging device from the first charging device in the charging station, wherein the first preset available power of the first charging device is greater than the first output demand power of the first charging device. In the method of the embodiment of the present application, each charging device controls the power dispatching between the charging devices, thereby realizing the distributed control of power dispatching. The second charging device can borrow at least part of the remaining power of the first charging device from the first charging device in the charging station. The first charging device dispatches at least part of the remaining power of the first charging device to the second charging device in the charging station. The first charging device and the second charging device are connected to the same phase. Compared with the method in the related art that the failure of the power control unit will affect the inability of all charging devices in the charging station to perform power dispatching, the method of the embodiment of the present application can still perform functional dispatching between other charging devices in the charging station when any charging device fails.

[0121] The following is an example of the power scheduling method of the charging station in an embodiment of the present application, how the second device borrows at least part of the remaining power of the first charging device from the first charging device in the charging station, and how the first device schedules at least part of the remaining power of the first charging device to the second charging device in the charging station.

[0122] Optionally, the second charging device may send first power request information to the first charging device. The first charging device may send first power request response information to the second charging device in response to the first power request information of the second charging device. The second charging device may receive the first power request response information of the first charging device.

[0123] The first power request information includes the size of the first power borrowed by the second charging device from the first charging device. The first power request response information includes the size of the second power dispatched by the first charging device to the second charging device and the first dispatching duration, and the size of the second power is less than or equal to the size of the remaining power.

[0124] In one implementation, the first charging device may respond to the power request information of the second charging device and may broadcast the remaining power before sending the power request response information to the second charging device. Before the second charging device sends the first power request information to the first charging device, it may receive the remaining power of the first charging device broadcast by the first charging device.

[0125] Combine the following Figure 3 , describing the specific steps of the power dispatching method of the charging station under the above-mentioned method. Figure 3 A schematic diagram of a power dispatching method for a charging station provided in an embodiment of the present application Figure 3 .like Figure 3 As shown, the following steps may be included:

[0126] S301. A first charging device determines a first preset available power and a first output required power.

[0127] Exemplarily, each phase power line of the charging station is respectively provided with a first switch, and the first preset available power and the first output required power of the first charging device are determined. The smallest ratio of the rated power of the first switch of each phase power line connected to the first charging device to the number of charging devices connected to each phase power line can be determined, and the smallest ratio is determined as the first preset available power of the first charging device.

[0128] Combine the following Figure 4 Determining a first preset available power of a first charging device is described. Figure 4 A connection diagram of a charging device provided in an embodiment of the present application Figure 1 .like Figure 4 As shown, the charging station includes an A-phase power line, a B-phase power line, and a C-phase power line. A first switch A is set on the A-phase power line, a first switch B is set on the B-phase power line, and a first switch C is set on the C-phase power line. N charging devices such as charging device A1, charging device A2, and charging device AN are connected to the A-phase power line, M charging devices such as charging device B1, charging device B2, and charging device BM are connected to the B-phase power line, X charging devices such as charging device C1, charging device C2, and charging device CX are connected to the C-phase power line, and Y charging devices such as charging device T1, charging device T2, and charging device TY are respectively connected to the A-phase power line, the B-phase power line, and the C-phase power line, that is, the three-phase power line is connected. Each charging device is connected in communication.

[0129] The constraint power of the first switch A is , the constraint power of the second switch B is , the constraint power of the second switch C is For example.

[0130] The first preset available power of any charging device among the N charging devices, such as the charging device A1, the charging device A2 and the charging device AN .

[0131] The first preset available power of any charging device among the M charging devices, namely, the charging device B1, the charging device B2, and the charging device BM .

[0132] The first preset available power of any charging device among the X charging devices, namely, the charging device C1, the charging device C2, and the charging device CX .

[0133] The first preset available power of any charging device among the Y charging devices, namely, the charging device T1, the charging device T2, and the charging device TY .

[0134] It should be understood that in the above example of the embodiment of presetting the first preset available power for the charging device, the first preset available power of the N charging devices such as the charging device A1, the charging device A2 and the charging device AN is the same. Optionally, different first preset available powers can also be set as long as the sum of the powers of the multiple charging devices connected to the single-phase power line is less than or equal to the rated power of the first switch. Figure 4 For example, the A-phase power line in the The restrictions include: It is the first preset available power of the charging device Ai.

[0135] Referring to the first preset available power of the above-mentioned preset charging device, if the first charging device is any one of N charging devices such as charging device A1, charging device A2 and charging device AN, the first preset available power of the first charging device is determined to be equal .

[0136] Exemplarily, the first output demand power may be determined as the sum of the power demand of the electrical equipment connected to the first charging device and the power dispatched by the first charging device to other charging devices other than the second charging device, or as the sum of the rated output power of the first charging device and the power dispatched by the first charging device to other charging devices other than the second charging device.

[0137] Optionally, when the first charging device can detect the power demand of the electric device based on the detection method in the relevant technology, the first charging device can determine the sum of the power demand of the detected electric device and the power of other charging devices dispatched by the first charging device to the second charging device as the first output required power. As shown in formula (1):

[0138] Formula (1)

[0139] in, is the first output required power, is the power demand of the electric device connected to the first charging device, dispatching power from the first charging device to a charging device other than the second charging device, The power of the first charging device is dispatched to the j-th charging device.

[0140] Optionally, the first charging device may determine the first output required power as the sum of its rated output power and the power dispatched by the first charging device to other charging devices other than the second charging device. The rated output power of the first charging device is subject to hardware limitations of the first charging device, such as the conductor size of the charging gun configured by the first charging device, the circuit breaker capacity limitation, etc.

[0141] Formula (2)

[0142] in, is the first output required power, is the rated output power.

[0143] Optionally, the first charging device may periodically update the first preset available power and the first output required power.

[0144] S302: The first charging device determines whether the first preset available power is greater than the first output required power.

[0145] If yes, execute S303;

[0146] If not, execute S301.

[0147] S303: The first charging device broadcasts the amount of remaining power.

[0148] For example, the first charging device may send a power available message, which may include the remaining power and the address of the first charging device. The remaining power is the difference between the first preset power and the first output required power. = .

[0149] S304: The second charging device determines a second output required power and an actually available power.

[0150] For the second charging device, the power dispatched by the second charging device to other charging devices is zero.

[0151] Optionally, when the second charging device can detect the power demand of the electric device based on the detection method in the related art, the detected power demand of the electric device connected to the second charging device is determined as the second output power demand. As shown in formula (3):

[0152] Formula (3)

[0153] in, is the second output power requirement, The power required by the electric device connected to the second charging device.

[0154] Optionally, the second charging device may determine its rated output power as the first output required power. As shown in formula (4):

[0155] Formula (4)

[0156] in, is the second output power requirement, is the rated output power.

[0157] The actual available power of the second charging device is the sum of the second preset available power of the second charging device and the power borrowed by the second charging device. The power borrowed by the second charging device is the power dispatched to the second charging device by other charging devices other than the current second charging device. As shown in formula (5):

[0158] Formula (5)

[0159] in, is the actual available power of the second charging device, is a second preset available power of the second charging device, is the power borrowed by the second charging device, The power dispatched to the second charging device by the jth charging device among the charging devices whose power has been borrowed by the second charging device.

[0160] Optionally, the sum of the powers whose scheduling durations correspond to the powers borrowed by the second charging device and are greater than or equal to a preset threshold value can be used as the power borrowed by the second charging device. In this way, for the power whose scheduling duration is less than the preset threshold value, during the process of the second charging device requesting the first charging device to borrow, the scheduling relationship corresponding to the power will be disconnected because the scheduling duration ends. Therefore, when determining the power borrowed by the second charging device, the power whose scheduling duration is less than the preset threshold value can be excluded from the calculation.

[0161] The second preset available power of the second charging device may be determined by referring to the above step of determining the first preset available power, and the first charging device and the second charging device are connected to the same phase power line. Figure 4 The charging device shown in the figure, and the first preset available power of the charging device preset in the above embodiment, if the first charging device is any one of N charging devices such as charging device A1, charging device A2 and charging device AN, then the second charging device is another charging device of N charging devices such as charging device A1, charging device A2 and charging device AN, and the first preset available power of the first charging device equal , the first preset available power of the second charging device equal .

[0162] S305: The second charging device determines whether the second output required power is greater than the actual available power.

[0163] If yes, execute S306;

[0164] If not, execute S304.

[0165] S306: The second charging device sends first power request information to the first charging device.

[0166] The first power request information includes the magnitude of the first power that the second charging device borrows from the first charging device.

[0167] Optionally, the second charging device may determine the minimum value between the difference between the second output required power and the actual available power and the magnitude of the remaining power as the first power.

[0168] After the second charging device receives the remaining power sent by the first charging device, it can determine the difference between the second output required power and the actual available power, that is, the amount of power that the second charging device currently needs to borrow. The minimum value between the difference between the second output required power and the actual available power and the amount of the remaining power is determined as the first power, and a first power request message is sent to the first charging device, where the first power request message includes the first power. As shown in formula (6):

[0169] Formula (6)

[0170] in, is the first power, is the second output power requirement, is the actual available power of the second charging device, It is the remaining power sent by the first charging device.

[0171] Exemplarily, the second charging device may send a power request message to the first charging device, where the power request message includes the first power, the address of the first charging device, and the address of the second charging device.

[0172] S307: The first charging device sends first power request response information to the second charging device.

[0173] The first charging device receives the first power request information of the second charging device, and in response to the first power request information of the second charging device, sends the first power request response information to the second charging device. The first power request response information includes the size of the second power scheduled by the first charging device to the second charging device and the first scheduling duration, and the size of the second power is less than or equal to the size of the remaining power.

[0174] Exemplarily, the first power request response information may be a power scheduling message, which includes the size of the second power, the first scheduling duration, the address of the first charging device, and the address of the second charging device. The address of the second charging device is the target address of the request for scheduling power, and the address of the first charging device is the source address of the request for scheduling power.

[0175] Optionally, in the process of generating the first power request response information by the first charging device, when the remaining power is greater than or equal to the first power, the first power may be determined as the second power, and when the remaining power is less than the first power, the remaining power may be determined as the second power. As shown in formula (7):

[0176] Formula (7)

[0177] in, is the second power, is the first power, is the remaining power.

[0178] In this mode, the first charging device satisfies the first power requested by the second charging device as much as possible to avoid the second charging device continuing to borrow from other charging devices. Since frequent establishment and disconnection of scheduling between charging devices will lead to unstable charging, therefore, in this mode, reducing the number of charging devices corresponding to the power borrowed by the second charging device can improve the stability of charging.

[0179] The first scheduling duration is the duration for the first charging device to dispatch power to the second charging device, which can be any preset value. For example, for an AC charging device, based on the requirement in GB / T 18487.1 that the time from the change of the pulse width modulation (PWM) duty cycle to the adjustment of the output power of the on-board charger should not be greater than 5 seconds, the first scheduling duration can be set to any duration greater than 5 seconds, for example, it can be set to 10 seconds, 20 seconds or 30 seconds. Optionally, different first scheduling durations can be set for DC and AC power sources.

[0180] The second charging device receives the first power request response information of the first charging device, and based on the above steps, dispatches at least part of the remaining power of the first charging device to the second charging device in the charging station.

[0181] In this way, since power scheduling can be achieved between charging devices, any number of charging devices can be set up. Through power scheduling, the power sum of each charging device is guaranteed not to exceed the total power limit of the charging station, thereby improving the flexibility of charging device settings. The method of the embodiment of the present application realizes distributed control of power scheduling. Compared with the method of controlling by a power control unit in the related art, the calculation amount is distributed to each charging device, thereby improving the stability of the power scheduling of the charging station.

[0182] Optionally, the second charging device may start timing after sending the first power request information to the first charging device. If the second charging device receives the first power request response information from the first charging device within a preset time period, it indicates that at least part of the remaining power of the first charging device is dispatched to the second charging device in the charging station. If the second charging device does not receive the first power request response information from the first charging device within the preset time period, the second charging device executes S304 to update the second output required power and the actual available power of the second charging device again, and request to borrow power again. In the current mode, the second charging device may request to borrow power from the first charging device or other charging devices other than the first charging device, and the charging device borrowed by the second charging device is connected to the same phase power line as the second charging device.

[0183] In one implementation, after the second charging device receives the first power request response information of the first charging device, it may also send the first power request confirmation information to the first charging device. The first charging device may also receive the first power request information, determine the first preset available power and the first output required power of the first charging device, and send the first power request response information to the second charging device when the first preset available power of the first charging device is greater than the first output required power. After sending the first power request response information to the second charging device, the first charging device may also receive the first power request confirmation information of the second charging device. The first power request confirmation information is used to confirm that the second charging device borrows the second power.

[0184] Combine the following Figure 5 , describing the specific steps of the power dispatching method of the charging station under the above-mentioned method. Figure 5 A schematic diagram of a power dispatching method for a charging station provided in an embodiment of the present application Figure 4 .like Figure 5 As shown, the following steps may be included:

[0185] S501: A second charging device determines a second output required power and an actually available power.

[0186] Optionally, the second charging device may periodically update the second output required power and the actual available power, that is, periodically determine the second output required power and the actual available power according to a preset time period.

[0187] S502: The second charging device determines whether the second output required power is greater than the actual available power.

[0188] If yes, execute S503;

[0189] If not, execute S501.

[0190] S503: The second charging device sends first power request information to the first charging device.

[0191] The first power request information includes the magnitude of the first power that the second charging device borrows from the first charging device.

[0192] For example, the second charging device may determine the difference between the second output required power and the actual available power as the first power. In this manner, if the second output required power of the second charging device is greater than the actual available power, the second charging device actively requests to borrow power from other charging devices. As shown in formula (8):

[0193] Formula (8)

[0194] in, is the first power, is the second output power requirement, is the actual available power of the second charging device.

[0195] Exemplarily, the second charging device may broadcast a power request message, where the power request message includes the address of the second charging device and the first power.

[0196] S504: The first charging device determines a first preset available power and a first output required power.

[0197] S505: The first charging device determines whether the first preset available power is greater than the first output required power.

[0198] If yes, execute S506;

[0199] If not, execute S504.

[0200] S506: The first charging device sends first power request response information to the second charging device.

[0201] The first charging device receives the first power request information and sends the first power request response information to the second charging device. The first power request response information includes the magnitude of the second power scheduled by the first charging device to the second charging device and the first scheduling duration, and the magnitude of the second power is less than or equal to the magnitude of the remaining power.

[0202] Exemplarily, the first charging device may send a power scheduling message to the second charging device, the power scheduling message including the size of the second power, the first scheduling duration, the address of the first charging device and the address of the second charging device. The first charging device may determine the size of the second power as the minimum value between the size of the remaining power of the first charging device and the first power in the first power request information.

[0203] S507: The second charging device sends first power request confirmation information to the first charging device.

[0204] The first power request confirmation information is used to confirm that the second charging device borrows the second power.

[0205] Exemplarily, the second charging device may send a secondment confirmation response message to the first charging device, where the secondment confirmation response message includes the magnitude of the second power, the first scheduling duration, the address of the first charging device, and the address of the second charging device.

[0206] The first charging device receives the first power request confirmation information of the second charging device, and based on the above steps, dispatches at least part of the remaining power of the first charging device to the second charging device in the charging station.

[0207] The above embodiment illustrates the specific steps of dispatching at least part of the remaining power of the first charging device to the second charging device in the charging station.

[0208] Optionally, after dispatching at least part of the remaining power of the first charging device to the second charging device in the charging station, the first charging device may also send a second power request response message to the second charging device in response to the second power request information upon receiving the second power request information from the second charging device and upon receiving the third power request information from the third charging device.

[0209] Among them, the second power request information includes the size of the third power borrowed by the second charging device from the first charging device, the third power request information includes the size of the fourth power borrowed by the third charging device from the first charging device, and the second power request response information includes the size of the fifth power of the second charging device dispatched by the first charging device and the second scheduling duration, and the size of the fifth power is less than or equal to the size of the remaining power.

[0210] Exemplarily, the first charging device and the second charging device already have a scheduling relationship, that is, the first charging device has scheduled at least part of the remaining power to the second charging device. When there is still remaining power in the first charging device, if the second charging device sends a second power request message to the first charging device again, and the first charging device receives the second power request message sent by the second charging device and also receives the third power request message sent by the third charging device, then the first charging device first responds to the second power request message and sends a second power request response message to the second charging device. The second power request message includes the size of the third power borrowed by the second charging device from the first charging device, and the third power request message includes the size of the fourth power borrowed by the third charging device from the first charging device.

[0211] Optionally, the first charging device sends a second power request response message to the second charging device in response to the second power request message. If the third power is less than the remaining power, part of the remaining power is dispatched to the second charging device according to the size of the third power. If the third power is greater than or equal to the remaining power, all of the remaining power is dispatched to the second charging device according to the size of the remaining power.

[0212] Optionally, when the third power is less than the remaining power, the first charging device may continue to respond to the third power request information sent by the third charging device and send a power request response message in response to the third power request information to the third charging device. Exemplarily, the first charging device may determine the minimum value between the difference between the magnitude of the remaining power and the magnitude of the third power and the magnitude of the fourth power, and dispatch at least part of the remaining power to the third charging device according to the magnitude of the minimum value.

[0213] In the power dispatching method of the charging station provided in the embodiment of the present application, after the first charging device dispatches at least part of the remaining power of the first charging device to the second charging device in the charging station, the first charging device can also send a second power request response message to the second charging device in response to the second power request message when receiving the second power request message from the second charging device and receiving the third power request message from the third charging device. In this way, the scheduling relationship between the charging devices that already have a scheduling relationship is maintained, and frequent disconnection of scheduling between the charging devices is avoided, thereby improving the stability of power dispatching and further improving the stability of the charging devices in the charging station supplying power to the electrical equipment.

[0214] Optionally, after the second charging device borrows at least part of the remaining power of the first charging device from the first charging device in the charging station, the second charging device may also receive the size of the remaining power of the first charging device broadcast by the first charging device, and receive the size of the remaining power of the fifth charging device broadcast by the fifth charging device. When the second output required power is greater than the actual available power, sixth power request information is sent to the first charging device, and the sixth power request information includes the size of the seventh power borrowed by the second charging device from the first charging device.

[0215] Exemplarily, after the second charging device borrows at least part of the remaining power of the first charging device from the first charging device in the charging station, that is, the first charging device and the second charging device already have a scheduling relationship. When the second charging device receives the remaining power of the first charging device broadcasted by the first charging device again, and also receives the remaining power of the fifth charging device broadcasted by the fifth charging device, and the second output required power is greater than the actual available power, the second charging device first sends the sixth power request information to the first charging device. The sixth power request information includes the seventh power that the second charging device borrows from the first charging device.

[0216] Optionally, the second charging device sends a sixth power request message to the first charging device, and after borrowing all the remaining power of the first charging device from the first charging device in the charging station, if the sixth power is greater than the remaining power, the second charging device again determines the second output demand power and the actual available power, and the second output demand power is still greater than the actual available power. In this case, the second charging device can send a corresponding power request message to the fifth charging device.

[0217] Optionally, after the second charging device borrows at least part of the remaining power of the first charging device from the first charging device in the charging station, the second charging device may periodically send power request information to the second charging device. For example, the first scheduling duration for the second charging device to borrow power from the first charging device is 20 seconds, and the second charging device may use 18 seconds as the interval duration for sending power request information to the first charging device, and periodically send power request information to the first charging device. In this way, the second charging device actively maintains the scheduling relationship with the first charging device, avoids frequent disconnection of scheduling between charging devices, and improves the stability of power scheduling.

[0218] In the power scheduling method of the charging station provided in the embodiment of the present application, after the second charging device borrows at least part of the remaining power of the first charging device from the first charging device in the charging station, it receives the magnitude of the remaining power broadcasted by the first charging device and the fifth charging device respectively, and sends the sixth power request information to the first charging device when the second output required power is greater than the actual available power. In this way, the scheduling relationship is maintained between the charging devices that already have a scheduling relationship, avoiding frequent disconnection of scheduling between the charging devices, improving the stability of power scheduling, and further improving the stability of the charging devices in the charging station supplying power to the electrical equipment.

[0219] Optionally, when the second output demand power decreases and the change in the second output demand power decrease is greater than a first threshold, the second charging device may determine the change as a first value; determine the minimum power value in the power seconded to the second charging device, if the minimum power value is less than the first value, use the difference between the first value and the minimum power value as the new first value, remove the minimum power value from the power seconded to the second charging device, repeat this step until the minimum power value is greater than the first value, and send a fifth power request message to the fourth charging device corresponding to the minimum power value of the power seconded to the second charging device, the fifth power request message includes the size of the sixth power seconded by the second charging device to the fourth charging device; the size of the sixth power is the minimum power value of the power of the second charging device minus the first value.

[0220] Figure 6 A schematic diagram of a process for reducing the borrowed power of a second charging device provided in an embodiment of the present application. Taking the variation greater than the first threshold as an example, Figure 6 As shown, the following steps may be included:

[0221] S601: Determine the change amount as a first value.

[0222] S602: Determine a minimum power value among the powers borrowed to the second charging device.

[0223] S603: Determine whether the minimum power value is less than the first value.

[0224] If yes, execute S604;

[0225] If not, execute S606.

[0226] S604: Take the difference between the first value and the minimum power value as a new first value.

[0227] S605: Eliminate the minimum power value from the power borrowed to the second charging device.

[0228] S606: Send fifth power request information to the fourth charging device corresponding to the minimum power value of the power borrowed from the second charging device.

[0229] The fifth power request information includes the magnitude of the sixth power borrowed by the second charging device from the fourth charging device; the magnitude of the sixth power is the minimum power value of the power of the second charging device minus the first value.

[0230] For example, the second charging device has borrowed power from charging device A, charging device B and charging device C, the power borrowed from charging device A is 20, the power borrowed from charging device B is 10, the power borrowed from charging device C is 8, and the second output required power is reduced by 15. Figure 6 A description will be given of a method for processing when the second output required power decreases.

[0231] Execute S601 to determine the change 15 as the first value, execute S602 to determine the minimum power value of 8 among the powers 20, 10, and 8 borrowed to the second charging device, execute S603 to determine that the minimum power value 8 is less than the first value 15, then execute S604 to use the difference 7 between the first value 15 and the minimum power value 8 as the new first value, execute S605 to remove the minimum power value from the power borrowed to the second charging device, that is, the power currently borrowed to the second charging device is 20 and 10. It should be understood that after the first scheduling duration of the second charging device borrowing from the charging device C, the scheduling relationship between the second charging device and the charging device C is disconnected, that is, the power borrowed by the second charging device is reduced by 8.

[0232] S602 is executed again to determine that the minimum power value of the power 20 and 10 borrowed to the second charging device is 10, and S603 is executed to determine that the minimum power value 10 is greater than the first value 7, then S606 is executed to send the fifth power request information to the charging device B corresponding to the minimum power value 10, and the charging device B is the fourth charging device. The fifth power request information includes the size of the sixth power borrowed by the second charging device from the fourth charging device, and the size of the sixth power is the minimum power value 10 of the power of the second charging device minus the first value 7. It should be understood that the power borrowed by the second charging device from the charging device B has been reduced by 7. In combination with the above embodiment, the power borrowed by the second charging device has been reduced by 8, and the current power borrowed by the second charging device has been reduced by 15.

[0233] In this manner, when the second output power requirement decreases and the change in the second output power requirement decreases is greater than the first threshold, the size of the power borrowed by the second charging device is further reduced, thereby improving the stability of power scheduling between charging devices. In the process of reducing the size of the power borrowed by the second charging device when the second output power requirement decreases, the method of gradually processing the minimum power value in the power borrowed to the second charging device ensures that the charging device corresponding to the minimum power value in the power borrowed to the second charging device gradually reduces the size of the borrowed power, avoids multiple adjustments to the scheduling between the second charging device and multiple charging devices, and improves the stability of power scheduling.

[0234] The power dispatching method of the charging station of the present application is applied to the first charging device in the charging station. The first charging device determines the first preset available power and the first output required power of the first charging device. When the first preset available power is greater than the first output required power, the first charging device dispatches at least part of the remaining power of the first charging device to the second charging device in the charging station, wherein the second output required power of the second charging device is greater than the actual available power of the second charging device. In the method of the embodiment of the present application, each charging device controls the power dispatching between charging devices, thereby realizing the distributed control of power dispatching. The first charging device can control the dispatching of the power of the first charging device to the second charging device in the charging station. Compared with the method in the related art that the failure of the power control unit will affect the inability of all charging devices in the charging station to perform power dispatching, the method of the embodiment of the present application can still perform functional dispatching between other charging devices in the charging station when any charging device fails.

[0235] Combine the following Figure 7 The following describes a case where each charging device is connected to at least one phase of the power line via at least one second switch.

[0236] Figure 7 A connection diagram of a charging device provided in an embodiment of the present application Figure 2 ,like Figure 7 As shown, each phase power line of the charging station is respectively provided with a first switch, and each charging device is connected to at least one phase power line via at least one second switch.

[0237] In this manner, the first charging device may send third power request response information to the second charging device in response to the fourth power request information of the second charging device, thereby dispatching at least part of the remaining power of the first charging device to the second charging device in the charging station.

[0238] In this manner, the second charging device may send fourth power request information to the first charging device, and receive third power request response information from the first charging device.

[0239] The fourth power request information includes at least one third switch, and the size of the third power borrowed by the second charging device corresponding to each third switch from the first charging device, and the third switch is a second switch shared by the second charging device and the first charging device; the third power request response information includes the size of the fourth power dispatched from the first charging device corresponding to at least one fourth switch of at least one third switch to the second charging device and the third scheduling duration, the size of the fourth power corresponding to each fourth switch is less than or equal to the size of the remaining power of the first charging device corresponding to each fourth switch, and the size of the remaining power of the first charging device corresponding to each fourth switch is the difference between the first preset power and the first output required power of the first charging device corresponding to each fourth switch.

[0240] Table 1 is a relationship table between a second switch and a corresponding charging device provided in an embodiment of the present application. As shown in Table 1, S1 to S5 represent 5 second switches, and L1 to L4 represent 4 charging devices. The horizontal charging device corresponding to the table marked with "1" in the vertical table of the second switch in the figure is the charging device corresponding to the second switch.

[0241] Table 1 Relationship between the second switch and the corresponding charging device

[0242]

[0243] Taking the second switch S1 as an example, the charging device L1, the charging device L2 and the charging device L4 are all charging devices corresponding to the second switch S1. When the second switch S1 is disconnected, the charging device corresponding to the second switch S1 cannot be charged, that is, the connection between the charging device corresponding to the second switch S1 and the single-phase power supply is disconnected. Therefore, the charging device whose charging is affected by the on-off of the second switch S1 is the charging device corresponding to the second switch S1.

[0244] Taking the charging device L1 and the charging device L2 as an example, the second switch S1 and the second switch S2 are second switches shared by the charging device L1 and the charging device L2.

[0245] Exemplarily, the power corresponding to the second switch S1 is the sum of the first preset power of the charging device L1 at the second switch S1, the first preset power of the charging device L2 at the second switch S1, and the first preset power of the charging device L4 at the second switch S1. Exemplarily, taking the power corresponding to the second switch S1 as the magnitude of the rated power, the sum of the first preset power of the charging device L1 at the second switch S1, the first preset power of the charging device L2 at the second switch S1, and the first preset power of the charging device L4 at the second switch S1 is the magnitude of the rated power of the second switch S1.

[0246] In one achievable manner, before the first charging device sends third power request response information to the second charging device in response to the fourth power request information of the second charging device, the first charging device may also broadcast the remaining power of the first charging device corresponding to each third switch.

[0247] Combine the following Figure 8 , describing the specific steps of the power dispatching method of the charging station under the above-mentioned method. Figure 8 A schematic diagram of a power dispatching method for a charging station provided in an embodiment of the present application Figure 5 .like Figure 8 As shown, the following steps may be included:

[0248] S801. A first charging device determines a first preset available power and a first output required power.

[0249] Exemplarily, for each third switch, a ratio of the rated power of the third switch to the number of charging devices controlled by the third switch is determined as the first preset power of the first charging device corresponding to the third switch, as shown in formula (9):

[0250] Formula (9)

[0251] in, is the first preset power of the first charging device corresponding to the third switch Sn, is the rated power of the third switch Sn, is the number of charging devices controlled by the third switch.

[0252] Referring to the second switch in Table 1, the number of charging devices controlled by the second switch S1 is 3, and the number of charging devices controlled by the second switch S2 is 2. Taking the first charging device as the charging device L1 as an example, the first preset power of the charging device L1 corresponding to the second switch S1 is , the first preset power of the charging device L1 corresponding to the second switch S2 is , the first preset power of the charging device L1 corresponding to the second switch S3 is . , and May be the same or different.

[0253] Exemplarily, for each third switch, the sum of the power demand power of the electrical equipment connected to the first charging device and the power of the first charging device corresponding to the third switch dispatched to other charging devices other than the second charging device, or the sum of the rated output power of the first charging device and the power of the first charging device corresponding to the third switch dispatched to other charging devices other than the second charging device, is determined as the first output demand power of the first charging device corresponding to the third switch.

[0254] For example, the first charging device is the charging device L1 in Table 1, and the second charging device is the charging device L2 in Table 1. The first charging device and the second charging device share the third switch S1 and the third switch S2. For example, for the third switch S1, the power demand of the electric device connected to the first charging device L1 is w1, and the power of the first charging device L1 dispatched to the charging device L4 in the power corresponding to the third switch S1 is w2, then the first output demand power of the first charging device L1 corresponding to the third switch S1 is the sum of w1 and w2. The power of the first charging device L1 dispatched to the charging device L4 is w2, which is zero, indicating that the first charging device L1 does not dispatch power to the charging device L4 in the power corresponding to the third switch S1.

[0255] For example, for the third switch S1 , the rated output power of the first charging device is w3 , the power dispatched from the first charging device L1 to the charging device L4 is w2 , and the first output required power of the first charging device L1 corresponding to the third switch S1 is the sum of w3 and w2 .

[0256] S802: The first charging device determines whether the first preset available power is greater than the first output required power.

[0257] If yes, execute S803;

[0258] If not, execute S801.

[0259] S803: The first charging device broadcasts the magnitude of the remaining power of the first charging device corresponding to each third switch.

[0260] Exemplarily, the first charging device determines the difference between the first preset power of the first charging device corresponding to each third switch and the first output required power as the size of the remaining power of the first charging device corresponding to each third switch.

[0261] Taking the first charging device as the charging device L1 in Table 1 as an example, the third switch may be the second switch S1, the second switch S2, and the second switch S3. The remaining power of the first charging device corresponding to the second switch S1, the remaining power of the first charging device corresponding to the second switch S2, and the remaining power of the first charging device corresponding to the second switch S3 are broadcast.

[0262] Exemplarily, the first charging device broadcasts a power available message, and the power available message includes the address of the first charging device, each third switch, and the remaining power of the first charging device corresponding to each third switch. For example, if the first charging device corresponding to the second switch S1 does not have remaining power, the power available message broadcast by the first charging device only includes the remaining power of the first charging device corresponding to the second switch S2 and the remaining power of the first charging device corresponding to the second switch S3.

[0263] S804: The second charging device determines a second output required power and an actually available power of the second charging device.

[0264] Exemplarily, the minimum value between the minimum value of the actual available power of the second charging device corresponding to each third switch and the second required output power of the second charging device is determined as the second required output power of the second charging device.

[0265] Taking the second charging device as the charging device L1 in Table 1 as an example, the third switches corresponding to the charging device L1 include the second switch S1, the second switch S2, and the second switch S3. Assume that the preset power of the charging device L1 corresponding to the second switch S1 is 100, the preset power of the charging device L1 corresponding to the second switch S2 is 120, and the preset power of the charging device L1 corresponding to the third switch S3 is 120, the charging device borrowed power of the charging device L1 corresponding to the second switch S1 is 100, the charging device borrowed power corresponding to the second switch S2 is 80, and the charging device borrowed power corresponding to the second switch S3 is 50, and the second output required power of the second charging device is 200. In this case, the actual available power of the charging device L1 corresponding to the second switch S1 is 200, the actual available power of the charging device L1 corresponding to the second switch S2 is 200, and the actual available power of the charging device L1 corresponding to the second switch S3 is 170. Then, the minimum value of the actual available power of the second charging device corresponding to each third switch, 170, is determined as the second output required power of the second charging device.

[0266] In this manner, the charging device borrowing power of the charging device L1 corresponding to the second switch S1 is reduced from 100 to 70, and the charging device borrowing power of the charging device L1 corresponding to the second switch S2 is reduced from 80 to 50.

[0267] Optionally, if the minimum value of the actual available power of the second charging device corresponding to each third switch is 170, and the second output required power of the second charging device is reduced to 150, then 150 is determined as the second output required power of the second charging device. In this manner, the charging device borrowing power of the charging device L1 corresponding to the second switch S1 is reduced to 50, the charging device borrowing power of the charging device L1 corresponding to the second switch S2 is reduced to 30, and the charging device borrowing power of the charging device L1 corresponding to the second switch S3 is reduced to 30.

[0268] S805: The second charging device determines whether the second output required power is greater than the actual available power.

[0269] If yes, execute S806;

[0270] If not, execute S804.

[0271] S806: The second charging device sends fourth power request information to the first charging device.

[0272] The fourth power request information includes at least one third switch and the size of the third power borrowed by the second charging device corresponding to each third switch from the first charging device.

[0273] Exemplarily, for each third switch, the difference between the second output required power and the actual available power of the second charging device corresponding to each third switch is determined as the size of the third power borrowed by the second charging device corresponding to each third switch from the first charging device.

[0274] Referring to Table 1, the first charging device is the charging device L1 in Table 1. If the information broadcast by the first charging device includes the size of the remaining power of the first charging device corresponding to the second switch S1, the size of the remaining power of the first charging device corresponding to the second switch S2, and the size of the remaining power of the first charging device corresponding to the second switch S3.

[0275] Taking the second charging device as the charging device L2 in Table 1 as an example, the second charging device can send a fourth power request information to the first charging device, wherein the fourth power request information includes the size of the third power borrowed by the second charging device from the first charging device for the second switch S1, and the size of the third power borrowed by the second charging device from the first charging device for the second switch S2.

[0276] Taking the second charging device as the charging device L4 in Table 1 as an example, the second charging device can send fourth power request information to the first charging device, where the fourth power request information includes the magnitude of the third power borrowed by the second charging device from the first charging device for the second switch S1.

[0277] Exemplarily, the second charging device may send a power request message to the first charging device, which may include at least one third switch, the size of the third power borrowed by the second charging device corresponding to each third switch from the first charging device, and the addresses of the first charging device and the second charging device.

[0278] S807: The first charging device sends third power request response information to the second charging device.

[0279] The first charging device responds to the fourth power request information of the second charging device by sending a third power request response information to the second charging device. The third power request response information includes the magnitude of the fourth power and the third scheduling duration of the fourth power dispatched from the first charging device to the second charging device corresponding to at least one fourth switch of at least one third switch, and the magnitude of the fourth power corresponding to each fourth switch is less than or equal to the magnitude of the remaining power of the first charging device corresponding to each fourth switch.

[0280] Exemplarily, the first charging device sends a power scheduling message to the second charging device, which may include the size of the fourth power and the third scheduling duration of the first charging device to the second charging device corresponding to at least one fourth switch in at least one third switch, and the addresses of the first charging device and the second charging device.

[0281] The second charging device receives the third power request response information of the first charging device. Through the above steps, at least part of the remaining power of the first charging device corresponding to at least one third switch is dispatched to the second charging device.

[0282] One possible implementation method is that, before determining the first preset available power and the first output required power of the first charging device, the first charging device may also receive fourth power request information, and after sending third power request response information to the second charging device, may also receive second power request confirmation information from the second charging device, wherein the second power request confirmation information is used to confirm that the second charging device has borrowed at least part of the fourth power corresponding to the fourth switch.

[0286] If yes, execute S903;

[0287] If not, execute S901.

[0288] S903: The second charging device sends fourth power request information to the first charging device.

[0289] Exemplarily, the second charging device can broadcast fourth power request information, which includes at least one third switch and the size of the third power borrowed by the second charging device corresponding to each third switch from the first charging device, and the third switch is a second switch shared by the second charging device and the first charging device.
