Description

Technical Field

[0001] The present invention belongs to the technical field of electric vehicle charging, and in particular relates to a device and method for controlling a charging pile cluster. Background Art

[0002] In a cluster of N charging stations, due to the total load, only M (M < N) of them can be powered simultaneously, while the remaining (NM) stations are temporarily disconnected from the grid and unable to provide charging service. In this situation, if the number of charging users exceeds M, later users will be forced to wait in line. This will not meet the needs of users with particularly urgent charging needs. While technically possible, simply disconnecting power to a charging station to protect those in urgent need of charging services would disrupt the fair "first-come, first-served" queuing system and could easily encourage deliberate "cutting in line," making it impractical in practice. However, objectively, the urgency of charging varies among users. Therefore, it is possible to reasonably adjust the charging queue order, based on the principle of "urgent first, less urgent later," with the permission of the charging users, to meet urgent charging needs while preserving the interests of other users. Summary of the Invention

[0003] The purpose of the present invention is to provide a charging pile cluster control device and method that conforms to the principle of fairness and can meet the needs of users who need expedited charging.

[0004] The technical solution of the present invention is:

[0005] A charging pile cluster control device, characterized in that it includes a load monitoring module, a user interface, an acceptance and review module, a user profile module, and a charging pile switching module;

[0006] The load monitoring module monitors the total power load of the charging pile cluster in real time and sends the monitoring data to the user interface and the charging pile switching module;

[0007] The user interface is provided at each charging pile within the charging pile cluster and provides different input interfaces to the user based on the monitoring data provided by the load monitoring module: when the current total power load is lower than the set upper limit, only the normal charging interface is enabled; when the current total power load reaches the set upper limit, only the expedited charging interface is enabled, and the expedited charging request input by the user, including the user's identity information and the duration of the requested expedited charging, is received, and this information is transmitted to the acceptance and review module;

[0008] The receiving and auditing module calls the file of the urgent charging user stored in the user file module, judges whether the urgent charging user meets the preset condition, and if yes, sends a switching instruction to the charging pile switching module, and if not, sends information rejecting the urgent charging request to the user interface;

[0009] After receiving the switching instruction from the receiving and auditing module, the charging pile switching module calls the files of all users charging in the charging pile cluster in the user file module, selects one charging pile to be powered off according to the preset power-off rule, powers on the charging pile where the urgent charging user is located within the urgent charging time length required by the urgent charging user, ends the urgent charging and restores the power supply to the previously powered-off charging pile when the urgent charging time length is reached, and transmits the urgent charging time length data of the urgent charging user to the user file module; during the urgent charging, when the current total power load is lower than the set upper limit value, the charging pile switching module preferentially restores the power supply to the previously powered-off charging pile.

[0010] The user file module records and accumulates the allowed power-off time length submitted by each user each time from the user interface, and records and accumulates the urgent charging time length of each urgent charging user each time from the charging pile switching module.

[0011] A charging pile cluster control method using the charging pile cluster control device of claim 1, comprising the following steps:

[0012] When the user interface displays the normal charging interface, the charging user can input identity information and voluntarily select the allowed power-off time length in the current charging process, and these information is transmitted to the user file module and controls the start of the normal charging process of the charging pile;

[0013] When the user interface displays the urgent charging interface, the urgent charging user can input an urgent charging request, including identity information and urgent charging time length data, and these information is transmitted to the receiving and auditing module;

[0014] B. The receiving and auditing module calls the file of the urgent charging user stored in the user file module, calculates the difference between the accumulated allowed power-off time length and the accumulated urgent charging time length, and if the difference is greater than 0, it is judged that the urgent charging user meets the preset condition, otherwise it is judged that the urgent charging user does not meet the preset condition;

[0015] C. The preset power-off rule executed by the charging pile switching module is to call the allowed power-off time length data voluntarily selected by each user during the current charging process from the user file module, and select the one with the largest value to power off the charging pile where it is located.

[0016] D. When the power-off time of the power-off charging pile reaches the allowed power-off time length in the current charging process, and the urgent charging time length required by the urgent charging user is not reached, the charging pile switching module repeats step C, selects another charging pile to be powered off, and restores the power supply to the previously powered-off charging pile.

[0017] The beneficial effects of the present application are: since the urgent charging user is set with a qualification condition, i.e. he is required to provide an opportunity to allow himself to be powered off to guarantee the urgent charging of others in advance, in order to obtain the right to request urgent charging, the behavior of deliberately "adding a queue" is avoided; since the user who voluntarily provides the longest power-off time length (considering that his charging demand is relatively not urgent) is preferentially selected to be powered off, the loss caused to the powered-off user is minimized to no actual loss. Thus, the needs of the urgent charging user are met, the fairness of the charging order is maintained, and a good atmosphere of mutual assistance among charging users is formed.
