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

[0089] The exemplary embodiments will be described in detail herein below with reference to the drawings. In the following description, the same drawings reference numbers are used to denote like or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Rather, they are merely examples of apparatuses 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 realized by a power controller. The control of power scheduling is centralized 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] Therefore, the present application provides a power scheduling method for a charging station. The method is applied to any charging device in the charging station. If the charging device determines that the preset available power is greater than the output demand power, the charging device can control at least part of the remaining power of the charging device to be scheduled to other charging devices in the charging station that need to borrow power. In the method of the present application, the charging device can control the power scheduling between the charging devices, and realize distributed control of power scheduling. Compared with the method in the related art in which the failure of the power control unit will affect all charging devices in the charging station and the charging devices cannot perform power scheduling, in the method of the present application, the other charging devices in the charging station can still perform power scheduling in the case of failure of any charging device.

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

[0093] The technical solutions of the present application and how the technical solutions solve the above technical problems will be 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 can not be described again in some embodiments. The embodiments of the present application will be described below with reference to the drawings.

[0094] Figure 1 Flowchart of a power scheduling method for a charging station provided by an embodiment of the present application Figure One The power scheduling method for the charging station is applied to a first charging device in the charging station. As shown in Figure 1 The power scheduling method for the charging station may, for example, include the following steps:

[0095] S101, determining a first preset available power and a first output demand power of the first charging device.

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

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

[0098] The first output demand power is the power required by the first charging device to charge the electrical equipment and the power scheduled by the first charging device to other charging devices except the second charging device.

[0099] The first preset available power of the first charging device is determined, for example, the rated power of a switch on a single-phase power line to which the first charging device is connected can be determined, and the first preset available power of each charging device on the single-phase power line is set in advance, and the first preset available power of each charging device can be equal or unequal, and 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. Further, the first preset available power of each charging device can be pre-stored in any storage space of each charging device, and the first charging device can read the first preset available power from the storage space of the first charging device when determining the first preset available power of the first charging device.

[0100] In the case that the first charging device does not schedule power supply to other charging devices, the first output demand power of the first charging device is determined, and the power demand of the electrical equipment connected to the first charging device is obtained, and the power demand of the electrical equipment is determined as the first output demand power of the first charging device. For example, the rated output power of the first charging device is obtained and determined as the first output demand power of the first charging device.

[0101] In the case that the first charging device has power scheduled to other charging devices, the first output demand power of the first charging device is determined, and the power demand of 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 except the second charging device are obtained, and the sum of the power is determined as the first output demand power of the first charging device.

[0102] S102, in the case that the first preset available power is greater than the first output demand power, at least part of the remaining power of the first charging device is scheduled to the second charging device in the charging station.

[0103] The size of the remaining power is the difference between the first preset power and the first output demand power. The remaining power is the power that can be scheduled by the first charging device to the second charging device.

[0104] The second output demand power 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 connected to the same phase power line as the first charging device. The second output demand power of the second charging device is greater than the actual available power of the second charging device, which indicates that the actual available power of the second charging device is insufficient to meet the second output demand power of charging the charging device.

[0105] The actual available power is a sum of a second preset available power of the second charging device and a borrowed power of the second charging device, and the borrowed power of the second charging device is power scheduled to the second charging device by other charging devices except the second charging device.

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

[0107] The power scheduling method of the charging station of the present application is applied to a first charging device in the charging station. The first charging device determines a first preset available power of the first charging device and a first output demand power, and in a case where the first preset available power is greater than the first output demand power, at least part of the remaining power of the first charging device is scheduled to a second charging device in the charging station, where a second output demand power of the second charging device is greater than an actual available power of the second charging device. The method of the embodiments of the present application controls power scheduling between charging devices by each charging device, and realizes distributed control of power scheduling. Compared with the method in the related art in which failure of a power control unit will affect all charging devices in the charging station and the charging devices cannot perform power scheduling, in a case where any charging device fails, other charging devices in the charging station can still perform power scheduling.

[0108] Figure 2 A flowchart of a power scheduling method of a charging station provided by the embodiments of the present application Figure Two . The power scheduling method of the charging station is applied to a second charging device in the charging station, as shown in Figure 2 , for example, can include the following steps:

[0109] S201, determining a second output demand power and an actual available power of the second charging device.

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

[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 borrowed power of the second charging device.

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

[0113] In the case where the second charging device has not borrowed power, the actual available power of the second charging device is determined, and the second preset available power of the second charging device is obtained and determined as the actual available power of the second charging device.

[0114] In the case where the second charging device has borrowed power from other charging devices, the actual available power of the second charging device is determined, and the sum of the second preset available power of the second charging device and the borrowed power of the second charging device is obtained and determined as the actual available power of the second charging device.

[0115] S202, in the case where the second output demand power is greater than the actual available power, at least part of the remaining power of the first charging device in the charging station is borrowed.

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

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

[0118] The second output demand power is greater than the actual available power, which indicates that the power that the second charging device can currently output is less than the power required to charge the power-using device. In this case, the second charging device can borrow at least part of the remaining power of the first charging device in the charging station. For example, the second device can send a request to the first charging device for the size of the borrowed power, 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, in the case of a power control unit failure, to ensure power safety, all charging devices in the charging station are set to be unavailable. In the method of the embodiment of the present application, in the case of a first charging device failure, to ensure power safety, only the charging device connected to the same phase power line as the first charging device is set to be unavailable. Compared with the method in the related art in which the power control unit failure affects all charging devices in the charging station, the influence range of a single point failure on the charging station is reduced.

[0120] The power scheduling method of the charging station of the present application is applied to a second charging device in the charging station. The second charging device determines the second output required power and the actual available power of the second charging device. In the case where the second output required power is greater than the actual available power, the second charging device borrows at least part of the residual power of a first charging device in the charging station from the first charging device, wherein the first preset available power of the first charging device is greater than the first output required power of the first charging device. In the method of the embodiment of the present application, each charging device controls the power scheduling between the charging devices, realizing distributed control of power scheduling. The second charging device can borrow at least part of the residual power of the first charging device in the charging station from the first charging device. The first charging device schedules at least part of the residual 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 in which the power control unit failure will affect all charging devices in the charging station and the charging devices cannot perform power scheduling, in the case of any charging device failure, the other charging devices in the charging station can still perform power scheduling.

[0121] The power scheduling method of the charging station of the embodiment of the present application, how the second device borrows at least part of the residual power of the first charging device in the charging station from the first charging device, and how the first device schedules at least part of the residual power of the first charging device to the second charging device in the charging station will be described by way of example.

[0122] Optionally, the second charging device can send first power request information to the first charging device. The first charging device can 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 can 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 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 residual power.

[0124] In an implementable manner, before the first charging device sends the power request response information to the second charging device in response to the power request information of the second charging device, the first charging device can also broadcast the size of the remaining power. Before the second charging device sends the first power request information to the first charging device, the second charging device can also receive the size of the remaining power of the first charging device broadcast by the first charging device.

[0125] The specific steps of the power scheduling method of the charging station in the above manner will be described below in combination with Figure 3 . Figure 3 The flowchart of the power scheduling method of the charging station provided by the embodiment of the present application is shown in Figure Three . As shown in Figure 3 , the method can include the following steps:

[0126] S301, the first charging device determines the first preset available power and the first output demand power.

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

[0128] The determination of the first preset available power of the first charging device will be described below in combination with Figure 4 , Figure 4 The connection of the charging device provided by the embodiment of the present application is shown in Figure One . As shown in Figure 4 , the charging station includes an A-phase power line, a B-phase power line and a C-phase power line. The A-phase power line is provided with a first switch A, the B-phase power line is provided with a first switch B, and the C-phase power line is provided with a first switch C. 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 connected to the A-phase power line, the B-phase power line and the C-phase power line respectively, i.e. connected to three-phase power lines. The charging devices are communicatively connected.

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

[0130] The first preset available power of any one of 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 one of the M charging devices, such as the charging device B1, the charging device B2, and the charging device BM .

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

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

[0134] It should be understood that in the above examples, the first preset available power of the charging device A1, the charging device A2, and the charging device AN, and the first preset available power of the N charging devices are the same. Alternatively, different first preset available powers can also be set, as long as the sum of the powers of the multiple charging devices connected by the single-phase power line is less than or equal to the rated power of the first switch. Taking the A-phase power line in the single-phase power line as an example, the following limit condition needs to be met: Figure 4 , wherein is the first preset available power of the charging device Ai.

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

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

[0137] Alternatively, in the case where the first charging device can detect the power demand of the electrical equipment based on the detection method in the related art, the first charging device can determine the detected power demand of the electrical equipment and the sum of the powers of the first charging device and the other charging devices other than the second charging device as the first output demand power. As shown in formula (1):

[0138] ​ Formula (1)

[0139] wherein, is the first output demand power, is the power demand of the power-using equipment connected with the first charging device, is the power of the first charging device dispatched to the charging device other than the second charging device, is the power of the first charging device dispatched to the jth charging device.

[0140] Optionally, the first charging device can determine the sum of the rated output power of the first charging device and the power of the first charging device dispatched to other charging devices other than the second charging device as the first output demand power. The rated output power of the first charging device is limited by the hardware of the first charging device, such as the conductor size of the charging gun configured by the first charging device, the circuit breaker capacity limit, etc.

[0141] Formula (2)

[0142] wherein, is the first output demand power, is the rated output power.

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

[0144] S302, the first charging device determines whether the first preset available power is greater than the first output demand power.

[0145] If yes, S303 is executed;

[0146] If no, S301 is executed.

[0147] S303, the first charging device broadcasts the size of the residual power.

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

[0149] S304, the second charging device determines the second output demand power and the actual available power.

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

[0151] Optionally, in a case where the second charging device can detect the power demand of the electrical equipment based on a detection method in the related art, the detected power demand of the electrical equipment connected with the second charging device is determined as the second output demand power. As shown in equation (3):

[0152] Equation (3)

[0153] wherein, the second output demand power, the power demand of the electrical equipment connected with the second charging device.

[0154] Optionally, the second charging device can determine the rated output power thereof as the first output demand power. As shown in equation (4):

[0155] Equation (4)

[0156] wherein, the second output demand power, 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 borrowed power of the second charging device, and the borrowed power of the second charging device is the power dispatched to the second charging device by other charging devices except the second charging device. As shown in equation (5):

[0158] Equation (5)

[0159] wherein, the actual available power of the second charging device, the second preset available power of the second charging device, the borrowed power of the second charging device, the power dispatched to the second charging device by the jth charging device in the charging devices whose borrowed power is borrowed by the second charging device.

[0160] Optionally, the sum of the borrowed power whose dispatch duration is greater than or equal to the preset threshold value in the borrowed power of the second charging device can be taken as the borrowed power of the second charging device. In this way, for the power whose dispatch duration is less than the preset threshold value, in a process in which the second charging device requests to borrow from the first charging device, the dispatch relationship corresponding to the power will be disconnected due to the end of the dispatch duration, and thus the borrowed power of the second charging device can not include the power whose dispatch duration is less than the preset threshold value.

[0161] The second preset available power of the second charging device can refer to the steps of determining the first preset available power described above, and the first charging device and the second charging device are connected to the same phase power line. Referring to Figure 4 The first preset available power of the charging device in the above embodiment, if the first charging device is any one of the N charging devices of the charging device A1, the charging device A2, and the charging device AN, then the second charging device is another charging device of the N charging devices of the charging device A1, the charging device A2, and the charging device AN, and the first preset available power of the first charging device is equal to , and the first preset available power of the second charging device is equal to .

[0162] S305, the second charging device determines whether the second output demand power is greater than the actual available power.

[0163] If yes, S306 is performed;

[0164] If no, S304 is performed.

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

[0166] The first power request information includes the size of the first power borrowed by the second charging device from the first charging device.

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

[0168] After the second charging device receives the remaining power sent by the first charging device, the difference between the second output demand power and the actual available power, i.e., the size of the power currently needed to be borrowed by the second charging device, can be determined. The minimum value between the difference between the second output demand power and the actual available power and the size of the remaining power is determined as the first power, and the first power request information including the first power is sent to the first charging device. As shown in formula (6):

[0169] Formula (6)

[0170] Wherein, is the first power, is the second output demand power, is the actual available power of the second charging device, is the remaining power sent by the first charging device.

[0171] ​​Exemplarily, the second charging device can send a power request message to the first charging device, the power request message comprising the first power, an address of the first charging device and an 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 first power request response information to the second charging device. The first power request response information comprises a size of a second power scheduled by the first charging device to the second charging device and a first scheduling duration, and the size of the second power is less than or equal to the size of the residual power.

[0174] Exemplarily, the first power request response information can be a power scheduling message, the power scheduling message comprising the size of the second power, the first scheduling duration, an address of the first charging device and an address of the second charging device. The address of the second charging device is a target address requesting to schedule power, and the address of the first charging device is a source address requesting to schedule power.

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

[0176] Formula (7)

[0177] Wherein, is the second power, is the first power, is the residual power.

[0178] In this way, the first charging device can meet the first power requested by the second charging device as much as possible to avoid the second charging device continuing to borrow power from other charging devices. Since frequent establishment and disconnection of scheduling between charging devices can lead to unstable charging, in this way, the number of charging devices corresponding to the power borrowed by the second charging device is reduced, and the stability of charging can be improved.

[0179] The first scheduling duration is a duration for the first charging device to schedule power to the second charging device, which can be any preset value. For example, for an alternating current charging device, based on the requirement in GB / T 18487.1 that the time for changing from a pulse width modulation (PWM) duty cycle to adjusting the output power of a vehicle-mounted charger should be no more than 5 seconds, the first scheduling duration can be set to any duration greater than 5 seconds, for example, 10 seconds, 20 seconds, or 30 seconds. Alternatively, different first scheduling durations can be set for direct current and alternating current power sources.

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

[0181] In this way, since power scheduling can be implemented between the charging devices, any number of charging devices can be set, and through power scheduling, the power of each charging device can be ensured not to exceed the total limited power of the charging station, and the flexibility of setting the charging devices is improved. The method of the embodiments of the present application implements distributed control of power scheduling, and compared with the method of controlling through a power control unit in the related art, the calculation amount is distributed to each charging device, and the stability of power scheduling of the charging station is improved.

[0182] Alternatively, the second charging device can 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 of the first charging device within a preset duration, it indicates that at least part of the remaining power of the first charging device is scheduled to the second charging device in the charging station. If the second charging device does not receive the first power request response information of the first charging device within the preset duration, the second charging device performs S304 to update the second output required power and the actual available power of the second charging device again, and requests for borrowed power again. In the current way, the second charging device can request for borrowed 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 an implementable manner, after receiving the first power request response information of the first charging device, the second charging device can further send first power request confirmation information to the first charging device. The first charging device can further receive the first power request information, determine the first preset available power and the first output demand power of the first charging device, and in a case where the first preset available power of the first charging device is greater than the first output demand power, send the first power request response information to the second charging device. After sending the first power request response information to the second charging device, the first charging device can further 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] The specific steps of the power scheduling method of the charging station in the above manner will be described below in combination with Figure 5 . Figure 5 The power scheduling method of the charging station provided by the embodiment of the present application Figure Four . As shown in Figure 5 , the method can include the following steps:

[0185] S501, the second charging device determines the second output demand power and the actual available power.

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

[0187] S502, the second charging device determines whether the second output demand power is greater than the actual available power.

[0188] If yes, S503 is performed;

[0189] If no, S501 is performed.

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

[0191] The first power request information includes the size of the first power borrowed by the second charging device from the first charging device.

[0192] Exemplarily, the second charging device can determine the difference between the second output demand power and the actual available power as the first power. In this manner, in a case where the second output demand 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] wherein, a first power, a second output demand power, an actual available power of the second charging device.

[0195] Exemplarily, the second charging device can broadcast a power request message, the power request message comprising an address of the second charging device and the first power.

[0196] S504, the first charging device determines the first preset available power and the first output demand power.

[0197] S505, the first charging device determines whether the first preset available power is greater than the first output demand power.

[0198] If yes, S506 is performed;

[0199] If no, S504 is performed.

[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 comprises a size of a second power scheduled by the first charging device to the second charging device and a first scheduling duration, and the size of the second power is less than or equal to the size of the remaining power.

[0202] Exemplarily, the first charging device can send a power scheduling message to the second charging device, the power scheduling message comprising the size of the second power, the first scheduling duration, an address of the first charging device and an address of the second charging device. Wherein, the first charging device can determine 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 as the size of the second power.

[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 can send a borrowing confirmation response message to the first charging device, the borrowing confirmation response message comprising 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.

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

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

[0208] Optionally, after scheduling at least part of the residual power of the first charging device to the second charging device, the first charging device can further send second power request response information to the second charging device in response to the second power request information, in the case that the second power request information of the second charging device and the third power request information of the third charging device are received.

[0209] 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 scheduled by the first charging device to the second charging device and the second scheduling duration, and the size of the fifth power is less than or equal to the size of the residual power.

[0210] For example, the first charging device and the second charging device have an existing scheduling relationship, that is, the first charging device has scheduled at least part of the residual power to the second charging device. In the case that the first charging device still has residual power, if the second charging device sends second power request information to the first charging device again, the first charging device receives the second power request information sent by the second charging device and also receives the third power request information sent by the third charging device. Then, the first charging device sends second power request response information to the second charging device in response to the second power request information. The second power request information includes the size of the third power borrowed by the second charging device from the first charging device, and the third power request information 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 second power request response information to the second charging device in response to the second power request information. If the third power is less than the residual power, part of the residual power is scheduled to the second charging device according to the size of the third power. If the third power is greater than or equal to the residual power, all of the residual power is scheduled to the second charging device according to the size of the residual power.

[0212] Optionally, in the case that the third power is less than the residual power, the first charging device can continue to send power request response information in response to the third power request information to the third charging device in response to the third power request information sent by the third charging device. For example, the first charging device can determine the minimum value between the difference between the size of the residual power and the size of the third power, and the size of the fourth power, and schedule at least part of the residual power to the third charging device according to the size of the minimum value.

[0213] The power scheduling method of the charging station provided in the embodiments of the present application, after the first charging device schedules 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 further send second power request response information to the second charging device in response to the second power request information, in the case that the second power request information of the second charging device is received and the third power request information of the third charging device is received. In this way, the scheduling relationship is maintained between the charging devices that have the scheduling relationship, the scheduling between the charging devices is avoided from being frequently disconnected, the stability of power scheduling is improved, and the stability of the charging device in the charging station to supply power to the power consumption equipment is further improved.

[0214] Optionally, after the second charging device borrows at least part of the remaining power of the first charging device in the charging station, the second charging device can further 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. In the case that the second output demand power is greater than the actual available power, the 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 in the charging station, that is, the first charging device and the second charging device have the scheduling relationship. In the case that the second charging device receives the size of the remaining power of the first charging device broadcast by the first charging device again, receives the size of the remaining power of the fifth charging device broadcast by the fifth charging device, and the second output demand 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 size of the seventh power borrowed by the second charging device from the first charging device.

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

[0217] Optionally, after the second charging device borrows at least part of the residual power of the first charging device in the charging station, the second charging device can periodically send power request information to the first charging device. For example, the first scheduling duration of the second charging device borrowing power from the first charging device is 20 seconds, and the second charging device can take 18 seconds as the interval duration of 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] The power scheduling method of the charging station provided by the embodiments of the present application can be used to receive the sizes of the residual powers respectively broadcast by the first charging device and the fifth charging device after the second charging device borrows at least part of the residual power of the first charging device in the charging station, and send sixth power request information to the first charging device in the case where the second output demand power is greater than the actual available power. In this way, the scheduling relationship between the charging devices that already have a scheduling relationship is maintained, the frequent disconnection of scheduling between the charging devices is avoided, the stability of power scheduling is improved, and the stability of the charging devices in the charging station supplying power to the power consumption equipment is further improved.

[0219] Optionally, in the case where the second output demand power decreases and the change amount of the second output demand power decreasing is greater than the first threshold value, the second charging device can determine the change amount as a first numerical value; determine the minimum power value in the power borrowed to the second charging device, if the minimum power value is less than the first numerical value, take the difference between the first numerical value and the minimum power value as a new first numerical value, eliminate the minimum power value from the power borrowed to the second charging device, and repeatedly execute the present step until the minimum power value is greater than the first numerical value, send fifth power request information to the fourth charging device corresponding to the minimum power value of the power borrowed to the second charging device, and the fifth power request information includes the size of the sixth power borrowed 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 numerical value.

[0220] Figure 6 A flowchart of a process of reducing borrowed power by a second charging device provided by the embodiments of the present application is shown in FIG. 8. Taking the case where the change amount is greater than the first threshold value as an example, as shown in FIG. 8, the process can include the following steps: Figure 6

[0221] S601, determine the change amount as a first numerical value.

[0222] S602, determine the minimum power value in the power borrowed to the second charging device.

[0223] S603, determine whether the minimum power value is less than the first numerical value.​

[0224] If yes, S604 is performed;

[0225] If no, S606 is performed.

[0226] S604, the difference between the first value and the minimum power value is taken as a new first value.

[0227] S605, the minimum power value is removed from the power borrowed to the second charging device.

[0228] S606, the fifth power request information is sent to the fourth charging device corresponding to the minimum power value of the power borrowed to the second charging device.

[0229] The fifth power request information includes the size of the sixth power borrowed 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.

[0230] Taking the case that the second charging device has borrowed power to charging device A, charging device B and charging device C, the power value borrowed by the second charging device to charging device A is 20, the power value borrowed by the second charging device to charging device B is 10, and the power value borrowed by the second charging device to charging device C is 8, and the second output demand power is reduced by 15, for example, in combination with Figure 6 The processing method in the case of reducing the second output demand power is described.

[0231] S601 is performed to determine the change amount 15 as the first value, S602 is performed to determine that the minimum power value of the power 20, 10 and 8 borrowed to the second charging device is 8, S603 is performed to determine that the minimum power value 8 is less than the first value 15, S604 is performed to take the difference 7 between the first value 15 and the minimum power value 8 as a new first value, and S605 is performed to remove the minimum power value from the power borrowed to the second charging device, that is, the current power borrowed to the second charging device is 20 and 10. It should be understood that after the first scheduling duration borrowed by the second charging device to charging device C, the scheduling relationship between the second charging device and charging device C is disconnected, that is, the power borrowed by the second charging device is reduced by 8.

[0232] The minimum power value in the power 20, 10 borrowed by the second charging device is 10, and the execution S603 determines that the minimum power value 10 is greater than the first value 7, so the execution S606 sends the fifth power request information to the charging device B corresponding to the minimum power value 10, that is, the fourth charging device, and the fifth power request information includes the size of the sixth power borrowed by the second charging device from the fourth charging device. 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 is reduced by 7. In combination with the above embodiment, the power borrowed by the second charging device is reduced by 8, and the total power borrowed by the second charging device is reduced by 15.

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

[0234] The power scheduling method of the charging station provided in the present application is applied to a first charging device in the charging station. The first charging device determines a first preset available power of the first charging device and a first output demand power, and schedules at least part of the residual power of the first charging device to a second charging device in the charging station when the first preset available power is greater than the first output demand power, where a second output demand power of the second charging device is greater than an actual available power of the second charging device. The method provided in the embodiments of the present application controls the power scheduling between the charging devices by each charging device, realizes distributed control of the power scheduling, and enables the first charging device to control the scheduling 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 in which the failure of the power control unit will affect all the charging devices in the charging station and the power scheduling cannot be performed, the method provided in the embodiments of the present application can still enable the power scheduling between the other charging devices in the charging station in the case of failure of any charging device.

[0235] The following will be described in combination with Figure 7 The connection between each charging device and at least one power supply line through at least one second switch is described.

[0236] Figure 7 A connection diagram of the charging device provided in the embodiments of the present application Figure Two AsFigure 7 As shown, each phase power line of the charging station is provided with a first switch, and each charging device is connected to at least one phase power line through at least one second switch.

[0237] In this mode, the first charging device can send third power request response information to the second charging device in response to the fourth power request information of the second charging device, so as to realize scheduling of at least part of the residual power of the first charging device to the second charging device in the charging station.

[0238] In this mode, the second charging device can send fourth power request information to the first charging device and receive the third power request response information of 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 scheduled by the first charging device corresponding to at least one fourth switch in the 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 residual power of the first charging device corresponding to each fourth switch, and the size of the residual power of the first charging device corresponding to each fourth switch is the difference between the first preset power and the first output demand power of the first charging device corresponding to each fourth switch.

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

[0241] Table 1 Relationship table of second switch and 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 the charging devices corresponding to the second switch S1. In the case where the second switch S1 is disconnected, the charging devices corresponding to the second switch S1 will be unable to charge, that is, the connection between the charging devices corresponding to the second switch S1 and the single-phase power supply is disconnected. Therefore, the charging devices affected by the on-off of the second switch S1 are the charging devices 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 the 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, the power corresponding to the second switch S1 is the rated power, and 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 size of the rated power of the second switch S1.

[0246] In an implementable manner, before the first charging device sends the 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 corresponding to each third switch can also broadcast the size of the remaining power of the first charging device.

[0247] The specific steps of the power scheduling method of the charging station in the above manner will be described below Figure 8 . Figure 8 The power scheduling method of the charging station provided by the embodiment of the present application has the flowchart Figure Five . As shown in Figure 8 , the method can include the following steps:

[0248] S801, the first charging device determines the first preset available power and the first output demand power.

[0249] Exemplarily, for each third switch, the 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] wherein, 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 for 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 , and 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 of the electrical equipment connected by the first charging device and the power of the first charging device corresponding to the third switch scheduled to the other charging device 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 scheduled to the other charging device 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] Taking the first charging device as the charging device L1 in Table 1 and the second charging device as the charging device L2 in Table 1 as an example, 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 electrical equipment connected by the first charging device L1 is w1, and the power of the first charging device L1 scheduled to the charging device L4 in the power corresponding to the third switch S1 is w2, and 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 scheduled to the charging device L4 is w2, which is zero, indicating that the first charging device L1 does not schedule 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, and the power of the first charging device L1 scheduled to the charging device L4 is w2, and then the first output demand 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 demand power.

[0257] If yes, S803 is performed;

[0258] If no, S801 is performed.

[0259] S803, the first charging device broadcasts the size of the residual 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 and the first output demand power of the first charging device corresponding to each third switch as the size of the residual 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 can be the second switch S1, the second switch S2 and the second switch S3. The second switch S1, the second switch S2 and the second switch S3 broadcast the sizes of the residual powers of the first charging device corresponding to the second switch S1, the second switch S2 and the second switch S3 respectively.

[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 size of the residual 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 residual power, the power available message broadcast by the first charging device only includes the sizes of the residual powers of the first charging devices corresponding to the second switch S2 and the second switch S3.

[0263] S804, the second charging device determines the second output required power and the actual available power of the second charging device.

[0264] Exemplarily, the minimum value between the minimum value of the actual available powers of the second charging device corresponding to each third switch and the second output required power of the second charging device is determined as the second output required 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 switch corresponding to the charging device L1 includes the second switch S1, the second switch S2 and the second switch S3. Assuming 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, the preset power of the charging device L1 corresponding to the third switch S3 is 120, the charging device L1 borrows power of 100 at the charging device corresponding to the second switch S1, borrows power of 80 at the charging device corresponding to the second switch S2, borrows power of 50 at the charging device corresponding to the second switch S3, 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 powers of the second charging device corresponding to each third switch, i.e. 170, is determined as the second output required power of the second charging device.

[0266] In this mode, the borrowed power of the charging device L1 at the charging device corresponding to the second switch S1 is reduced from 100 to 70, and the borrowed power of the charging device L1 at the charging device 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, 150 is determined as the second output required power of the second charging device. In this way, the borrowed power of the charging device L1 in the charging device corresponding to the second switch S1 is reduced to 50, the borrowed power of the charging device L1 in the charging device corresponding to the second switch S2 is reduced to 30, and the borrowed power of the charging device L1 in the charging device 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, S806 is executed;

[0270] If no, S804 is executed.

[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] For example, 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, taking the first charging device as 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 fourth power request information to the first charging device, and 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, and 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.

[0277] Exemplarily, the second charging device can send a power request message to the first charging device, and the message can include at least one third switch, a size of third power borrowed by the second charging device from the first charging device corresponding to each third switch, and 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 sends third power request response information to the second charging device in response to fourth power request information of the second charging device. The third power request response information includes a size of fourth power scheduled by the first charging device to the second charging device and a third scheduling duration corresponding to each of at least one fourth switch in the at least one third switch, and 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.

[0280] Exemplarily, the first charging device sends a power scheduling message to the second charging device, and the message can include a size of fourth power scheduled by the first charging device to the second charging device and a third scheduling duration corresponding to each of at least one fourth switch in the at least one third switch, and 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, and through the above steps, at least part of the remaining power of the first charging device corresponding to at least one third switch is scheduled to the second charging device.

[0282] In an implementable manner, before determining the first preset available power and the first output demand power of the first charging device, the first charging device can also receive fourth power request information, and after sending the third power request response information to the second charging device, the first charging device can also receive second power request confirmation information of the second charging device, and the second power request confirmation information is used to confirm that the second charging device borrows at least part of the fourth power corresponding to the fourth switch.
