Description

Technical Field

[0001] This invention relates to the field of charging technology, and in particular to a power adjustment method, system, electronic device, and storage medium based on a charging pile. Background Technology

[0002] With the explosive growth of new energy electric vehicles and other electric devices, the demand for charging piles and other charging equipment has also increased. Currently, the intelligent scheduling of charging pile power adopts a static allocation strategy, which only triggers the reallocation of power when a new car owner joins the charging process or when a car owner finishes charging.

[0003] However, during the charging process where the charging environment remains unchanged, there will be a certain deviation between the power actually required by the vehicle and the actual power supplied by the charging station. Traditional static allocation strategies are difficult to resolve the power deviation, leading to power overload or power redundancy at the charging station. Summary of the Invention

[0106] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0107] First, to introduce the method of this application, some key terms used below are defined.

[0108] Power supplied: The theoretical charging power that the charging gun is set to provide to the device being charged.

[0109] Reported power: The actual charging power value provided by the charging gun to the device being charged.

[0110] Maximum power: The maximum power value that the charging gun has under normal working conditions. When the actual charging power value of the charging gun exceeds this maximum power value, the charging gun is more likely to be damaged than under normal working conditions.

[0111] Minimum reserved power value: The minimum power value that the charging gun has under normal working conditions. When the actual charging power value of the charging gun is less than this minimum reserved power value, the charging gun cannot start charging.

[0112] The application environment of the method provided in the embodiments of this application is described below.

[0113] The method provided in this embodiment of the invention can be applied to, for example... Figure 1 In the power adjustment system based on charging piles, the power adjustment system 10 includes a charging management device 100 and a charging station 200. The charging station 200 includes at least one charging group 210, and a charging group 210 includes at least two charging piles 211. Each charging pile 211 includes multiple charging guns 211A. Each charging gun 211A can match one user at the same time to charge the user's device, such as a new energy electric vehicle.

[0114] The charging management device 100 is communicatively connected to the charging station 200 and is used to manage the charging station 200. The charging management device 100 can consist of one or more workstations or servers, and can monitor and collect data on the charging piles 211 and charging guns 211A, as well as process and analyze data for the entire charging station 200. The data that the charging management device 100 can acquire includes information on devices charging in the charging station 200, charging information for the charging piles 211, including the charging guns 211A, and user information corresponding to the charging devices.

[0115] In one embodiment, charging station 200 is a facility that provides charging services for electric vehicles in cities, highways, or industrial areas. Charging station 200 includes two charging groups 210, namely a first charging group and a second charging group. The allocation of charging groups 210 can be accomplished by charging management device 100, for example, the charging management device 100 can divide charging piles 211 using the same power supply point into one charging group 210.

[0116] Each charging group 210 may include at least two charging piles 211. For example, the first charging group 210 includes three charging piles 211, namely the first charging pile, the second charging pile, and the third charging pile. Each charging pile includes multiple charging guns 211A. For example, the first charging pile includes four charging guns 211A, namely the first charging gun, the second charging gun, the third charging gun, and the fourth charging gun. The charging guns 211A are used to electrically connect the electric vehicle to be charged and the charging pile 211, so that the charging pile 211 provides power to the electric vehicle for charging through the charging guns 211A.

[0117] The charging pile 211 and the charging gun 211A can provide charging outputs of different power. Specifically, the charging management device 100 controls the power output of the charging pile 211 and the charging gun 211A to adjust the power of the electric vehicle.

[0118] Understandably, the above Figure 1 The charging station and charging management equipment shown are only an example. In actual situations, equipment or modules can be integrated, adjusted, or added as needed. For example, the charging station may also include a power supply system, which mainly provides power to the charging equipment. It may consist of primary equipment (switches, transformers, lines, etc.) and secondary equipment (including detection, protection, control devices, etc.), source filtering devices, etc. This application does not impose any restrictions on this.

[0119] Based on the above power adjustment system, the power adjustment method based on charging piles provided in this application can be realized.

[0120] Please see Figure 2 , Figure 2 This is a flowchart illustrating a charging power allocation method provided in an embodiment of this application. Figure 2 The power adjustment method shown can be executed by a charging management device, and the method may include:

[0121] S21. Determine the priority identifier of the target charging gun.

[0122] The target charging station includes multiple charging guns, including the target charging gun. Each charging gun has a corresponding priority identifier, which is used to determine the position of the corresponding charging gun in the adjustment sequence when adjusting the power.

[0123] In one embodiment, the priority identifier includes four levels, corresponding to four different user types: users who have paused charging, users who prioritize charging, VIP users, and regular users. That is, the four different types of users have different priority identifiers and different orders when allocating and adjusting charging power, the specific order of which will be detailed later.

[0124] It should be noted that the priority identifiers include levels that are not limited to the four levels shown in the example. There may be more levels to correspond to other user types, such as VVIP users or whitelisted customers, which are not limited here.

[0125] It should also be noted that the priority identifier is adjustable. When the user information or charging status corresponding to the target charging gun changes, the priority identifier will also be adjusted accordingly, which requires re-determining the priority identifier of the target charging gun.

[0126] S22. Determine the output power of the target charging gun based on the priority identifier.

[0127] The target charging station has a power limit. Because of this limit, the target charging station cannot support all the charging guns within it to output at maximum power. Therefore, it is necessary to allocate the power output of each charging gun within the charging station. Since each charging gun is assigned a different priority identifier, the power output of all charging guns, including the target charging gun, can be determined based on these priority identifiers.

[0128] In one embodiment, the target charging station includes four charging guns, each with a maximum power of 10kW. Since the target charging station's power limit is 20kW, it's impossible for all four charging guns to operate at their maximum power of 10kW. In this case, based on priority indicators, one charging gun is allocated 0kW of power, one is allocated 10kW, one is allocated 2kW, and the remaining charging gun is allocated 8kW.

[0129] In this embodiment, the target charging gun can be any one of the four charging guns, thereby enabling the power output of the target charging gun to be determined based on the priority identifier.

[0130] It should be noted that the power data in the above embodiments are only for illustrating the technical solutions of this application and do not limit the present invention.

[0131] S23. Obtain the reported power of the target charging gun.

[0132] Once the charging gun determines the output power, it charges the charging device according to that output power. Simultaneously, the charging gun collects and acquires the power it reports.

[0133] In reality, due to the difference between actual operating conditions and theoretical conditions, the reported power is not strictly equal to the transmitted power. As long as the deviation between the two is within a certain fluctuation range, it is acceptable, and the charging gun is considered to be in normal working condition. However, if the actual charging power of the charging gun deviates significantly from the set transmitted power, it indicates that the charging gun is malfunctioning and needs to be adjusted in power or shut down for maintenance. Only by obtaining the reported power in real time and comparing the reported power with the transmitted power can the working status of the target charging gun be detected.

[0134] In one embodiment, the charging pile allocates a power of 10kW to the target charging gun, and the charging gun detects and reports a power of 9kW. The difference between the two is 1kW, which is within an acceptable fluctuation range. Therefore, it can be determined that the charging gun is working normally and there is no need to adjust the power temporarily.

[0135] In another embodiment, the charging pile allocates a power of 10 kW to the target charging gun, and the charging gun detects and reports a power of 6 kW. The difference between the two is 4 kW, which is far beyond the acceptable fluctuation range. Therefore, step S24 needs to be performed on the charging gun to adjust the power.

[0136] It should be noted that the reported power detection can be performed in real time or at intervals, and those skilled in the art can choose according to the actual situation. Regardless of the detection method used, the acquired reported power corresponds to the transmitted power used for comparison; that is, the time when the acquired reported power is used for comparison should not be earlier than the time when the transmitted power is adjusted.

[0137] S24. Based on the power output and the reported power output, control the target charging pile to perform a power release operation or a power recovery operation on the target charging gun.

[0138] Specifically, after determining that the target charging gun needs power adjustment, it is necessary to compare the sent power with the reported power to determine the abnormality type of the target charging gun, and then perform the corresponding power adjustment operation according to the abnormality type of the target charging gun. The power adjustment operation is one of the power release operation and the power recovery operation.

[0139] Please see Figure 3 , Figure 3 This is a flowchart illustrating the process of performing a power release or power recovery operation on a target charging gun according to an embodiment of this application. The method includes the following steps:

[0140] S301. Determine whether the power sent down is greater than the power reported up.

[0141] When the target charging gun's transmit power is greater than its reported power, it indicates that the target charging gun has an abnormally high transmit power, and step S310 is executed. When the target charging gun's transmit power is less than its reported power, it indicates that the target charging gun has an abnormally low transmit power, and step S320 is executed.

[0142] S310. If the value is greater than the target value, then control the target charging pile to perform a power release operation on the target charging gun. Specifically, step S310 includes the following:

[0143] S311. Calculate the release power value of the target charging gun based on the transmitted power and the reported power.

[0144] The purpose of performing a power release operation on the target charging gun is to bring the target charging gun into a normal working state. Specifically, this means that the final reported power of the target charging gun is the same as the adjusted transmitted power, or the deviation between the two is within an acceptable fluctuation range.

[0145] Therefore, it can be determined that in order to reduce the transmitted power value to the reported power value, the releaseable power value of the target charging gun is the result of subtracting the reported power value from the transmitted power value, i.e., the releaseable power value = transmitted power value - reported power value.

[0146] In one embodiment, if the power transmitted is 10kW and the power reported is 6kW, then the calculated release power is 4kW.

[0147] S312. Determine the charging gun in the target charging pile that is in the waiting-to-receive state as the charging gun to be assigned.

[0148] When the power of the target charging gun decreases, it means that the target charging station has additional power redundancy, which can be allocated to other charging guns to improve the overall charging efficiency of the target charging station. Therefore, it is necessary to determine whether the charging guns in the target charging station other than the target charging gun can receive the releasable power value.

[0149] Specifically, in one embodiment, S312 includes the following steps:

[0150] S3121. Obtain the output power and upper limit of the charging gun in the target charging pile.

[0151] S3122. Determine whether the power output is less than the upper limit.

[0152] If the current power output is less than the upper power limit, proceed to step S3123 below. If the current power output is greater than or equal to the upper power limit, proceed to step S3124 below.

[0153] S3123. When the current power output is less than the upper limit of power, the charging gun is determined to be the charging gun to be assigned.

[0154] If the output power is less than the upper limit, it means that the charging gun is not working at full capacity. Therefore, the charging gun can be identified as a charging gun to be assigned, so as to increase the output power of the charging gun and improve the charging efficiency.

[0155] S3124. When the current power output is greater than or equal to the power limit, determine that the charging gun is not a charging gun to be assigned.

[0156] If the output power is greater than or equal to the upper limit, it indicates that the charging gun is already operating at full capacity or even overload. Continuing to increase the output power of the charging gun could easily damage it or cause other safety accidents. Therefore, it is necessary to ensure that the charging gun is not the one to be assigned.

[0157] In another embodiment, S312 includes the following steps:

[0158] S3125. Obtain the power output and reporting power of the charging gun in the target charging pile.

[0159] S3126. Determine whether the difference between the transmitted power and the reported power is less than a preset threshold.

[0160] If the difference between the transmitted power and the reported power is less than a preset threshold, proceed to step S3127 below; if the difference between the transmitted power and the reported power is greater than a preset threshold, proceed to step S3128 below.

[0161] S3127. When the difference between the current output power and the reported power is less than a preset threshold, the charging gun is determined to be a charging gun to be assigned.

[0162] If the difference between the current output power and the reported power is less than the preset threshold, it indicates that the charging gun is in normal working condition and its power can be adjusted. Therefore, the charging gun is determined to be a charging gun to be assigned.

[0163] S3128. When the difference between the current output power and the reported power is greater than or equal to a preset threshold, it is determined that the charging gun is not a charging gun to be assigned.

[0164] If the difference between the transmitted power and the reported power is greater than or equal to a preset threshold, it indicates that the charging gun also belongs to the type of abnormally high transmitted power. It is necessary to perform a power release operation on it, rather than allowing the charging gun to receive additional power from another target charging gun with abnormally high transmitted power. Therefore, it is determined that the charging gun is not a charging gun to be assigned.

[0165] It should be noted that the methods for determining the charging gun to be assigned in the above two embodiments can be used alone or in combination, and those skilled in the art can make adaptive adjustments as needed.

[0166] S313. Allocate power to the charging gun to be allocated based on the releasable power value.

[0167] Specifically, in one embodiment, S313 includes the following steps:

[0168] S3131. Determine the output power and upper limit of the charging gun to be assigned.

[0169] S3132. Determine the maximum receiving value of the charging gun to be allocated based on the transmitted power and the power limit value.

[0170] The maximum transmit power of the charging gun to be assigned during normal operation is the upper limit of power, which is the maximum transmit power after the charging gun to be assigned has increased its power. Therefore, the maximum receive value of the charging gun to be assigned can be determined as the result of the upper limit of power minus the transmit power value, that is, the maximum receive value = upper limit of power - transmit power value.

[0171] S3133. Allocate power to the charging gun to be allocated based on the maximum received value or the releasable power value.

[0172] Since both the maximum received value and the releaseable power value constrain the allocated power, the additional power allocated to the charging gun to be allocated cannot exceed the maximum received value to avoid damage to the charging gun and safety accidents. At the same time, the additional power allocated cannot exceed the releaseable power value to avoid the target charging gun not having enough redundant power to release, which would cause the target charging pile to be overloaded.

[0173] Specifically, to solve the above problem, S3133 also includes the following steps:

[0174] S31331. Determine whether the maximum received value is less than the releaseable power value.

[0175] S31332. If it is greater than or equal to the value, the output power of the charging gun to be allocated is increased according to the releasable power value.

[0176] When the maximum received value is greater than or equal to the releasable power value, it means that the charging gun to be assigned is sufficient to fully receive the releasable power value of the target charging gun. At this time, the releasable power value is used to increase the power transmitted to the charging gun to be assigned, and the power transmitted to the target charging gun is reduced to reach the reported power value.

[0177] S31333. If it is less than the maximum received value, the power of the charging gun to be assigned will be increased.

[0178] If the maximum received value is less than the releaseable power value, it means that even if the charging gun to be assigned increases to its maximum power limit, it cannot fully receive the releaseable power value of the target charging gun. In this case, the maximum received value is used to increase the transmission power of the charging gun to be assigned, and the transmission power of the charging gun to be assigned is increased to reach the maximum power limit.

[0179] S31334. Based on the maximum received value and the releasable power value, recalculate the releasable power value of the target charging gun.

[0180] When the power output of the charging gun to be assigned is increased by the maximum received value, it means that the charging gun to be assigned cannot fully receive the release power value of the target charging gun. Therefore, power needs to be allocated to another charging gun to be assigned, which requires recalculating the release power value of the target charging gun.

[0181] Specifically, the releaseable power value of the target charging gun at this time is the original releaseable power value minus the maximum receiving value of the assigned charging gun, that is, the recalculated releaseable power value = the original releaseable power value - the maximum receiving value.

[0182] Specifically, in this embodiment, the first charging gun to be allocated is defined as the charging gun among the charging guns that has not yet been allocated power, and the second charging gun to be allocated is the charging gun among the charging guns that has already been allocated power. The original releaseable power value of the target charging gun is 4kW, and the maximum receiving power value of the second charging gun to be allocated is 1kW. Therefore, the recalculated releaseable power value is 3kW. For the first charging gun to be allocated, subsequent calculations and judgments will use the recalculated 3kW as the releaseable power value.

[0183] It should be noted that there can be multiple first charging guns to be allocated, and the specific number is not limited. For example, in this embodiment, the maximum receiving power values ​​of the two first charging guns to be allocated are 2kW and 1kW, respectively, then the recalculated release power value is 1kW.

[0184] S31335. Allocate power to the first charging gun to be allocated based on the recalculated releasable power value.

[0185] Specifically, in this step, it is necessary to determine again the magnitude between the release power value of the target charging gun and the maximum receiving value of the first charging gun to be allocated, and allocate power to the first charging gun to be allocated according to the determination result. The specific process can be referred to step S313, which will not be elaborated here.

[0186] In some embodiments, after step S313, the method further includes:

[0187] S314. Allocate power to the charging pile to be assigned based on the releaseable power value. Specifically, this includes:

[0188] S3141. Determine whether the target charging station has a releaseable power value.

[0189] After the target charging station allocates power to all the charging guns it includes, the power output of the target charging gun may still not have reached the reported power, requiring further power release. Specifically, the target charging station still has a releaseable power value, i.e., the releaseable power value is greater than 0. Therefore, it is necessary to further determine whether the releaseable power value is 0. If it is not 0, then proceed to step S3142 below; if it is 0, then proceed to step S3145 below.

[0190] S3142. When the target charging station has a releaseable power value, determine the group containing the target charging station as the target group.

[0191] S3143. Identify the charging piles in the target group that are in the waiting-to-receive state as the charging piles to be allocated.

[0192] Due to the structure of the power adjustment system, the algorithm difficulty and loss of allocating power among charging piles belonging to the same group are both better than allocating power among charging piles in different groups. Therefore, when a target charging pile has a releaseable power value, the group containing the target charging pile is identified as the target group, and charging piles in the same target group that are in a waiting-to-receive state are identified as charging piles to be allocated.

[0193] Specifically, it is determined whether the power output of each charging pile in the target group has reached the power limit of the charging pile. If so, the charging pile is determined not to be a charging pile to be allocated; otherwise, the charging pile is determined to be a charging pile to be allocated.

[0194] S3144. Allocate power to the charging pile to be allocated based on the releaseable power value.

[0195] For the charging gun of the charging pile to be assigned, the power is allocated to the charging gun according to the release power value. The specific process can be referred to in steps S312 and S313, which will not be repeated here.

[0196] S3145. If the target charging station does not have a releaseable power value, end step S310.

[0197] If the target charging station does not have a release power value, it means that the power output of the target charging gun has been adjusted to the reported power, and the target charging station has completed the power release operation. Therefore, the power release operation step can be ended.

[0198] In some embodiments, after step S3144, the method further includes:

[0199] S315. Allocate power to the group to be allocated based on the releasable power value. Specifically, this includes:

[0200] S3151. Determine whether the target group has a releaseable power value.

[0201] After the target group allocates power to all the charging piles it includes, the power sent by the target charging gun may still not have reached the reported power, and further power needs to be released. Specifically, the target group still has a releaseable power value, that is, a releaseable power value greater than 0. Therefore, it is necessary to further determine whether the releaseable power value is 0. If it is not 0, then execute the following step S3152; if it is 0, then execute the following step S3154.

[0202] S3152. When the target group has a releasable power value, identify other groups in the waiting-to-receive state as the groups to be assigned.

[0203] Specifically, it is determined whether the overall power of groups outside the target group has reached the power limit of the group. If so, the group is determined not to be a group to be assigned; otherwise, the group is determined to be a group to be assigned.

[0204] S3153. Allocate power to the group to be allocated based on the releasable power value.

[0205] For the charging piles in the group to be assigned, refer to step S3143 to determine the charging piles to be assigned in the group, and then allocate power to the charging guns in the charging piles to be assigned according to the release power value. The specific process can be referred to steps S312 and S313, which will not be elaborated here.

[0206] It should be noted that if the target charging gun still has a releaseable power value after step S3153, that is, the releaseable power value is greater than 0, then the final output power of the target charging gun after releasing power in step S310 is the output power minus the allocated power value, or it can be calculated as the output power being the reported power plus the power that has not yet been allocated.

[0207] S3154. If there is no releasable power value in the target group, end step S310.

[0208] If there is no releaseable power value in the target group, it means that the power output of the target charging gun has been adjusted to the reported power, the target group has completed the power release operation, and the power release operation step can be ended.

[0209] Please refer to it again. Figure 3 Next, we will continue with S301, and then introduce S320, another step relative to S310.

[0210] S320: If the value is less than the target value, then control the target charging pile to perform a power recovery operation on the target charging gun. Specifically, step S320 includes the following:

[0211] S321. Calculate the receivable power value of the target charging gun based on the transmitted power and the reported power.

[0212] The purpose of performing power recovery operation on the target charging gun is to bring the target charging gun into normal working condition. Specifically, this means that the final reported power of the target charging gun is the same as the adjusted output power, or the deviation between the two is within an acceptable fluctuation range.

[0213] Therefore, it can be determined that in order to increase the transmitted power value to the reported power value, the receivable power value of the target charging gun is the result of subtracting the transmitted power value from the reported power value, i.e., receivable power value = reported power value - transmitted power value.

[0214] In one embodiment, if the transmitted power value is 4kW and the reported power value is 7kW, then the calculated receiveable power value is 3kW.

[0215] S322. Identify the charging gun in the target charging pile that is in a state of waiting to be recycled as the charging gun to be recycled.

[0216] When the power of the target charging gun increases, it indicates that the target charging station may be overloaded. It is necessary to reduce the output power of other charging guns to keep the overall output power of the target charging station below the theoretical upper limit. Therefore, it is necessary to determine whether the charging guns other than the target charging gun in the target charging station can reduce their power to offset the increased acceptable power value and keep the target charging station working normally.

[0217] Specifically, in one embodiment, S322 includes the following steps:

[0218] S3221. Obtain the output power and minimum reserved power value of the charging gun in the target charging pile.

[0219] S3222. Determine whether the power output is greater than the minimum reserved power value.

[0220] If the current power generation is greater than the minimum reserved power value, proceed to step S3223 below; if the current power generation is less than or equal to the minimum reserved power value, proceed to step S3224 below.

[0221] S3223. When the current output power is greater than the minimum reserved power value, the charging gun is determined to be a charging gun to be recycled.

[0222] If the output power is greater than the minimum reserved power value, it means that the charging gun has not yet reached the minimum load operation. The output power can be further reduced to recover part of the power of the charging gun and provide it to the target charging gun. Thus, the charging gun is identified as the charging gun to be recovered.

[0223] S3224. When the current power output is less than or equal to the minimum reserved power value, it is determined that the charging gun is not a charging gun to be recycled.

[0224] If the output power is less than or equal to the minimum reserved power value, it indicates that the charging gun is already operating at its minimum load, or even below the minimum load. Further reducing the output power of the charging gun could easily cause it to stop working altogether or perform ineffective operations. Therefore, it is necessary to determine whether the charging gun is intended for recycling.

[0225] In another embodiment, S322 includes the following steps:

[0226] S3225. Obtain the power output and reporting power of the charging gun in the target charging pile.

[0227] S3226. Determine whether the difference between the transmitted power and the reported power is greater than a preset threshold.

[0228] If the difference between the current power output and the reported power output is greater than a preset threshold, proceed to step S3227 below; if the difference between the current power output and the reported power output is less than or equal to a preset threshold, proceed to step S3228 below.

[0229] S3227. When the difference between the current output power and the reported power is greater than the preset threshold, the charging gun is determined to be a charging gun to be recycled.

[0230] If the difference between the current output power and the reported power is greater than the preset threshold, it indicates that the charging gun is in normal working condition, or that the charging gun is in a state of abnormally high output power. The output power can be adjusted and recycled. Therefore, the charging gun is determined to be a charging gun to be recycled.

[0231] In one embodiment, if the power output of the charging gun is 6kW and the power output is 5kW, with a deviation of +1kW, which is greater than the threshold of 0, the charging gun is in normal working condition and is therefore determined to be a charging gun to be recycled.

[0232] In another embodiment, the charging gun's output power is 9kW, the reported power is 5kW, the deviation is +4kW, which is greater than the threshold of 0. Although the charging gun is not in normal working condition, but rather has an abnormally high output power, it can still be determined that the charging gun is a charging gun to be recycled.

[0233] In another embodiment, the charging gun's output power is 2kW, the reported power is 5kW, the deviation is -2kW, which is less than the threshold of 0. Therefore, the charging gun's output power is abnormally low, and it is determined that the charging gun is not a charging gun to be recycled.

[0234] S3228. When the difference between the current output power and the reported power is less than or equal to a preset threshold, it is determined that the charging gun is not a charging gun to be recycled.

[0235] If the difference between the transmitted power and the reported power is less than or equal to the preset threshold, it indicates that the charging gun also belongs to the type with abnormally low transmitted power. It is necessary to increase the transmitted power of the charging gun, rather than letting the charging gun continue to reduce the transmitted power to recover power for the target charging gun. Therefore, it is determined that the charging gun is not the charging gun to be recovered.

[0236] It should be noted that the methods for determining the charging gun to be recycled in the above two embodiments can be used alone or in combination, and those skilled in the art can make adaptive adjustments as needed.

[0237] S323. The recoverable power value is the power to be recovered by the charging gun.

[0238] Specifically, in one embodiment, S323 includes the following steps:

[0239] S3231. Determine the priority identifier of the charging gun to be recycled.

[0240] Specifically, each charging gun to be recycled has a priority identifier. As the charging status of the corresponding charging gun changes, the priority identifier of the charging gun to be recycled may change compared to when the power adjustment started. Therefore, it is necessary to re-determine the priority identifier of the charging gun to be recycled.

[0241] S3232. Determine the power recovery sequence based on the priority identifier.

[0242] Each priority identifier has a different priority when recovering power, thus allowing all charging guns to be recovered to be sorted according to the priority identifier to obtain a power recovery sequence.

[0243] Specifically, in this embodiment, the priority identifier includes four levels, corresponding to users who have paused charging, users who are charging in priority, VIP users, and ordinary users, respectively. In the power recovery sequence, the charging guns corresponding to users who have paused charging are recovered first, followed by the charging guns corresponding to VIP users, and finally the charging guns corresponding to users who are charging in priority. The charging guns corresponding to users who have paused charging do not participate in power recovery because their charging power is completely reduced to 0.

[0244] It should be noted that the priority level is not limited to the four levels described in the above embodiments. The number of users corresponding to these levels can be increased, decreased, or changed compared to the four types of users in the above embodiments. The corresponding priority is also not limited to the embodiments. Those skilled in the art can make adaptive modifications in practical applications.

[0245] S3233: Recover power for each charging gun to be recovered in sequence according to the power recovery sequence.

[0246] Specifically, step S3233 includes the following:

[0247] S32331. Determine the output power and minimum reserved power value of the charging gun to be recycled.

[0248] S32332. Determine the maximum recycling value of the charging gun to be recycled based on the output power and the minimum reserved power value.

[0249] The minimum output power of the charging gun to be recycled during normal operation is the minimum reserved power value, which is the minimum output power of the charging gun to be recycled after reducing its power. Therefore, the maximum recycling value of the charging gun to be recycled can be determined as the output power value minus the minimum reserved power value, that is, the maximum recycling value = output power value - minimum reserved power value.

[0250] S32333: Based on the maximum recoverable value or the acceptable power value, recover the power of the charging gun to be recycled.

[0251] Since both the maximum recovery value and the acceptable power value constrain the recovery power, the power reduction allocated to the charging gun to be recovered cannot exceed the maximum recovery value to prevent the charging gun's output power from falling below the minimum reserved power value, causing the charging gun to stop working. At the same time, the power reduction during recovery cannot exceed the acceptable power value; otherwise, the target charging gun will receive too much power, causing power redundancy in the target charging pile and reducing the overall charging efficiency.

[0252] Therefore, to solve the above problem, S32333 also includes the following steps:

[0253] S323331. Determine whether the maximum recovery value is greater than the acceptable power value.

[0254] S323332. If it is greater than or equal to the acceptable power value, the power output of the charging gun to be recycled will be reduced accordingly.

[0255] When the maximum recovery value is greater than or equal to the acceptable power value, it means that the charging gun to be recovered is sufficient to fully release the acceptable power value of the target charging gun. At this time, the power output of the charging gun to be recovered is reduced based on the acceptable power value, and the power output of the target charging gun is increased to reach the reported power value.

[0256] S323333: If it is less than the maximum recovery value, then reduce the output power of the charging gun to be recycled according to the maximum recovery value.

[0257] If the maximum recovery value is less than the acceptable power value, it means that even if the power output of the charging gun to be recycled is reduced to the minimum reserved power value, it cannot fully provide the full acceptable power value required by the target charging gun. In this case, the power output of the charging gun to be recycled is reduced to the maximum recovery value, and the power output of the charging gun to be recycled is reduced to the minimum reserved power value.

[0258] S323334. Based on the maximum recovery value and the acceptable power value, recalculate the acceptable power value of the target charging gun.

[0259] When the power output of the charging gun to be recycled is reduced to the maximum recovery value, it means that the charging gun to be recycled cannot fully provide the acceptable power value required by the target charging gun. Therefore, it is necessary to recover power for another charging gun to be recycled, which requires recalculating the acceptable power value of the target charging gun.

[0260] Specifically, the receivable power value of the target charging gun at this time is the original receivable power value minus the maximum receivable power value of the recovered charging gun, that is, the recalculated receivable power value = the original receivable power value - the maximum recovery value.

[0261] Specifically, in this embodiment, the first charging gun to be recycled is defined as the charging gun whose power has not yet been recycled, and the second charging gun to be recycled is the charging gun whose power has already been recycled. The original acceptable power value of the target charging gun is 4kW, and the maximum recyclable power value of the second charging gun to be allocated is 1kW. Therefore, the recalculated acceptable power value is 3kW. For the first charging gun to be recycled, subsequent calculations and judgments will use the recalculated 3kW as the acceptable power value.

[0262] It should be noted that there can be multiple first charging guns to be recycled, and the specific number is not limited. For example, in this embodiment, the maximum recycling power values ​​of the two first charging guns to be recycled are 2kW and 1kW, respectively, so the recalculated receivable power value is 1kW.

[0263] S323335. Based on the recalculated acceptable power value, the power to be recovered by the first charging gun to be recycled is determined.

[0264] Specifically, in this step, it is necessary to determine again the magnitude between the acceptable power value of the target charging gun and the maximum recovery value of the first charging gun to be recycled, and allocate power to the first charging gun to be recycled according to the determination result. The specific process can be referred to step S323, which will not be elaborated here.

[0265] In some embodiments, after step S323, the method further includes:

[0266] S324. The recoverable power value is based on the power to be recovered by the charging pile. Specifically, this includes:

[0267] S3241. Determine whether the target charging station has a receivable power value.

[0268] After the target charging station has recovered power from all the charging guns it includes, the power output of the target charging gun may still not have reached the reported power, requiring further power recovery. Specifically, the target charging station still has a receivable power value, i.e., a receivable power value greater than 0. Therefore, it is necessary to further determine whether the receivable power value is 0. If it is not 0, proceed to step S3242 below; if it is 0, proceed to step S3245 below.

[0269] S3242. When the target charging station has a receivable power value, determine the group containing the target charging station as the target group.

[0270] S3243. Identify the charging piles in the target group that are in a state of pending recycling as charging piles to be recycled.

[0271] Due to the structure of the power adjustment system, the algorithm difficulty and losses for recovering power among charging piles belonging to the same group are better than those for recovering power among charging piles in different groups. Therefore, when a target charging pile has a receivable power value, the group containing the target charging pile is identified as the target group, and charging piles belonging to the same target group that are in a state of pending power recovery are identified as charging piles to be recovered.

[0272] Specifically, it is determined whether the power output of each charging pile in the target group has reached the minimum reserved power of the charging pile. If so, the charging pile is determined not to be a charging pile to be recycled; otherwise, the charging pile is determined to be a charging pile to be recycled.

[0273] S3244. The recoverable power value is the power to be recovered by the charging pile.

[0274] For the charging gun of the charging pile to be recycled, the recycling power of the charging gun is based on the acceptable power value. The specific process can be referred to in steps S322 and S323, which will not be elaborated here.

[0275] S3245. If the target charging station does not have a receivable power value, end step S320.

[0276] If the target charging station does not have a receivable power value, it means that the power output of the target charging gun has been adjusted to the reported power, and the target charging station has completed the power recovery operation. Therefore, the power recovery operation step can be terminated.

[0277] In some embodiments, after step S324, the method further includes:

[0278] S325. The recoverable power value is the power to be recovered for the group to be recovered. Specifically, this includes:

[0279] S3251. Determine whether the target group has a receivable power value.

[0280] After the target group has recovered power from all the charging piles it includes, the power transmitted by the target charging gun may still not have reached the reported power, requiring further power reception. Specifically, this means that the target group still has a receivable power value, i.e., a receivable power value greater than 0. Therefore, it is necessary to further determine whether the receivable power value is 0. If it is not 0, then proceed to step S3252 below; if it is 0, then proceed to step S3254 below.

[0281] S3252. When the target group has a receivable power value, identify other groups in the pending recovery state as pending recovery groups.

[0282] Specifically, it is determined whether the overall transmission power of groups outside the target group has reached the minimum reserved power of the group. If so, the group is determined not to be a group to be assigned; otherwise, the group is determined to be a group to be assigned.

[0283] S3253, The recoverable power value is the power of the group to be recovered.

[0284] For the charging piles in the group to be recycled, refer to step S3243 to determine the charging piles to be recycled in the group, and then use the recyclable power value to determine the power of the charging gun in the charging pile to be recycled. The specific process can be referred to steps S322 and S323, which will not be elaborated here.

[0285] It should be noted that if the target charging gun still has a receivable power value after step S3253, that is, the receivable power value is greater than 0, then the final output power of the target charging gun after releasing power in step S320 is the output power plus the recovered power value, or it can be calculated as the output power being the reported power minus the power that has not yet been recovered.

[0286] It should also be noted that if, after step S3253, the final output power of the target charging gun is still lower than the reported power and the deviation between the two is greater than the preset threshold, making the target charging gun still belong to the type of abnormally high output power, then in order to avoid overloading the target charging pile, the priority identifier corresponding to the target charging gun will be adjusted to the user level of suspended charging, and the final output power of the target charging gun will be reduced to 0, waiting for maintenance personnel to inspect and repair it.

[0287] S3254. If no receivable power value exists for the target group, end step S320.

[0288] If there is no receivable power value in the target group, it means that the power output of the target charging gun has been adjusted to the reported power, the target group has completed the power recovery operation, and the power recovery operation can be terminated.

[0289] In some embodiments, prior to step S21, the method further includes:

[0290] S201. Obtain the user information corresponding to the target charging gun.

[0291] Specifically, user information includes the user type, such as VVIP user, VIP user, ordinary user, blacklisted user, or whitelisted user.

[0292] S202. Generate a priority identifier for the target charging gun based on the user information.

[0293] The priority identifier is used to determine the order in which the target charging gun transmits and recovers power. Specifically, when determining the transmission power, it is allocated in the order of VVIP users, VIP users, and ordinary users; when recovering power, it is recovered in the order of ordinary users, VIP users, and VVIP users.

[0294] In some other embodiments, prior to step S21, the method further includes:

[0295] S203. Obtain the user information corresponding to the target charging gun.

[0296] Specifically, user information includes the user's planned charging time.

[0297] In some embodiments, a user can send a charging plan time to the power adjustment system via a smart terminal such as a mobile phone or laptop. After receiving the charging plan time, the power adjustment system adjusts the output power of the target charging gun corresponding to the user according to the charging plan time, so that the user's device to be charged can complete the charging task within the charging plan time.

[0298] S204. Obtain the estimated charging time of the target charging gun.

[0299] The power adjustment system generates the estimated charging time for the target charging gun based on the real-time reported power collected by the target charging gun and the charging task or charging progress of the device to be charged.

[0300] In one embodiment, the target charging gun reports a power of 5kW, the charging task is to charge the battery from 20% to 98%, and the estimated charging time is 40 minutes according to the preset charging curve.

[0301] S205. Generate a priority identifier for the target charging gun based on the charging plan time and the estimated charging time.

[0302] In one embodiment, if the user sets a charging plan time of 30 minutes, and the estimated charging time calculated by the power adjustment system is 40 minutes, then the priority identifier of the target charging gun corresponding to the user is set to the priority charging user level.

[0303] In another embodiment, if the user sets a charging plan time of 30 minutes, and the estimated charging time calculated by the power adjustment system is 40 minutes, then the priority identifier of the target charging gun corresponding to the user is set to the ordinary charging user level.

[0304] Please see Figure 4 , Figure 4 This is a schematic diagram illustrating a process for determining the output power of a target charging gun based on a priority identifier, as provided in an embodiment of this application.

[0305] S410. Determine the priority identifier of the charging gun in the target charging pile.

[0306] S420. Based on the priority identifier, determine the upper limit of the power output of all charging guns in the target charging pile.

[0307] Specifically, step S420 includes the following:

[0308] S421. Determine the number of charging guns corresponding to each priority identifier.

[0309] In some embodiments, the target charging station includes four charging guns, each corresponding to a user type with a priority identifier: priority charging user, paused charging user, VIP user, and regular user. Therefore, each priority identifier corresponds to one charging gun.

[0310] S422. Sort the charging guns according to the priority identifier to obtain the power allocation sequence.

[0311] In some embodiments, the power allocation sequence first determines the upper limit of the power allocated to users who have paused charging, then determines the upper limit of the power allocated to users who have priority charging, then determines the upper limit of the power allocated to VIP users, and finally determines the upper limit of the power allocated to ordinary users.

[0312] It is understood that in some other embodiments, the power allocation sequence corresponding to the priority identifier can be changed in order, for example, the upper limit of the power allocated to VIP users can be determined first, and the upper limit of the power allocated to priority charging users can be determined later.

[0313] S423. Determine the upper limit of the power output for each charging gun according to the power allocation sequence and priority identifier.

[0314] In some embodiments, the target charging pile has a maximum power of 20kW, the minimum reserved power of each charging gun is 3kW, the maximum power of the charging gun is 10kW, and the target charging pile includes 4 charging guns, which correspond to priority charging users, paused charging users, VIP users, and ordinary users, respectively.

[0315] Based on the power allocation sequence, the upper limit of the power output for charging guns of users who are temporarily suspending charging is first determined to be 0. Secondly, the upper limit of the power output for priority charging users is calculated as follows: (Charging pile power limit - minimum reserved power value x number of charging guns for low-priority users) / (number of charging guns for priority charging users), which is (20-3x2) / 1 = 14kW.

[0316] It should be noted that the number of charging guns marked as low priority does not include the number of charging guns used by users who have paused their charging process.

[0317] It should also be noted that since the value of 14kW is greater than the power limit of the charging gun of 10kW, the calculation is based on the power limit of the charging gun of 10kW.

[0318] Furthermore, since there are priority charging users in the power allocation sequence, the priority identifier of VIP users is reduced to the same level as that of ordinary users. That is, both VIP users and ordinary users calculate the upper limit of the power to be distributed according to the minimum reserved power value.

[0319] In some other embodiments, even if there are priority charging users in the power allocation sequence, the priority identifier of VIP users is still higher than that of ordinary users. Then, the upper limit of the power allocated to VIP users is calculated as (the upper limit of the remaining power of the charging pile - the minimum reserved power value x the number of charging guns of the low priority user) / (the number of charging guns of VIP users), that is, ((20-14)-3x1) / 1 = 3kw.

[0320] Finally, if there are no priority charging or VIP users in the power allocation sequence, the upper limit of the power allocated to ordinary users is equal to the upper limit of the charging pile power / the number of charging guns for ordinary users; if there are, the upper limit of the power allocated to the charging guns corresponding to ordinary users is set according to the minimum reserved power value.

[0321] S430: Based on the power allocation algorithm, determine the output power of the target charging gun according to the upper limit of the output power of all charging guns.

[0322] The power allocation algorithms include average allocation algorithm, weighted average algorithm, and first-in-first-out algorithm. The specific algorithm is selected based on the parameters.

[0323] Specifically, during the execution of the power allocation algorithm, the power output of each charging gun in the target charging station is allocated sequentially according to its priority identifier. For example, the charging guns for priority charging users are allocated first, followed by those for VIP users, and finally those for regular users.

[0324] In some embodiments, the target charging station first allocates power to all charging guns corresponding to priority users based on a power allocation algorithm. After determining the power output of the charging guns for priority users, the target charging station allocates power to VIP users based on the remaining allocable power value and the power allocation algorithm. The remaining allocable power value is the target charging station's maximum power value minus the total power output already allocated to priority users. If the remaining allocable power value is 0, the minimum reserved power value is directly allocated to VIP users to determine the power output.

[0325] It is understood that in this embodiment, the power transmission logic of the charging gun for ordinary users is the same as that for VIP users. The only difference is that the priority identifier of ordinary users is lower than that of VIP users, so it will not be described in detail.

[0326] Therefore, the technical solution of this application can achieve the following technical effects: First, the priority identifier of the target charging gun is determined. The target charging pile includes multiple charging guns, including the target charging gun. Second, based on the priority identifier, the output power of the target charging gun is determined. Then, the reported power of the target charging gun is obtained. Finally, based on the output power and the reported power, the target charging pile is controlled to perform a power release operation or a power recovery operation on the target charging gun. This achieves real-time dynamic adjustment of the target charging gun's power. By combining the priority identifier and real-time monitoring of the charging gun, the target charging gun, while determining the output power according to the priority identifier, can react to abnormal target charging guns by releasing or recovering power. This ensures the normal operation of the target charging gun while improving the overall charging efficiency and stable operation of the target charging pile.
