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 some charging pile clusters including N charging piles, due to the limitation of the total power load of the cluster, only M (M < N) charging piles can be powered at the same time, while the other (NM) charging piles are temporarily powered off and cannot provide charging services. At this time, if the number of charging users is more than M, the later users can only wait in line. This will not meet the needs of some users who are particularly in urgent need of charging. Although it is technically possible to take a simple approach of cutting off the power of a charging pile that is charging to protect the users who need to charge urgently, this approach actually destroys the fair order of "first come, first served" queuing for charging, and is likely to induce deliberate "jamming" bad behavior, so it is not feasible in reality. However, objectively, the urgency of charging for each charging user is usually different, so there is still a possibility of reasonably adjusting the charging queue order based on the principle of "first urgent and then slow" with the permission of the charging user, so as to meet the needs of urgent charging without harming the interests of other charging 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: 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; 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; The user interface is set at each charging pile in the charging pile cluster, and provides different input interfaces to the user according to 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 identity information and the duration of the expedited charging request, is received, and the information is transmitted to the acceptance and review module; The acceptance and review module calls the file of the expedited charging user stored in the user file module to determine whether the expedited charging user meets the preset conditions, and if so, sends a switching instruction to the charging pile switching module; if not, sends information rejecting the expedited charging request to the user interface; After receiving the switching instruction from the acceptance and review module, the charging pile switching module calls the files of all users who are charging in the current charging pile cluster in the user file module, and selects to cut off the power to one of the charging piles according to the preset power-off rule, and starts the power supply to the charging pile where the urgent charging user is located within the urgent charging time required by the urgent charging user; when the urgent charging time is reached, the current urgent charging is ended, and the power supply to the previously powered-off charging pile is restored; and the data of the current urgent charging time of the urgent charging user is transmitted to the user file module; during the urgent charging period, when the current total power load is lower than the set upper limit value, the charging pile switching module gives priority to restoring the power supply to the previously powered-off charging pile.

[0005] The user profile module records and accumulates the allowed power-off duration submitted by each user from the user interface, and records and accumulates the expedited charging duration of each expedited charging user from the charging pile switching module.

[0006] A charging pile cluster control method, which uses the charging pile cluster control device as claimed in claim 1, and comprises the following steps: When the user interface displays the normal charging interface, the charging user can enter identity information and voluntarily choose to enter the power-off duration allowed during this charging process. This information is transmitted to the user profile module and controls the start of the normal charging process of the charging pile; When the user interface displays the expedited charging interface, the expedited charging user can enter an expedited charging request, including his / her identity information and the duration of the requested expedited charging, and this information is transmitted to the acceptance and review module. B. The acceptance and review module calls the file of the expedited charging user stored in the user file module, and calculates the difference between the cumulative allowed power-off time provided by the user and the cumulative expedited charging time used. If it is greater than 0, it is determined that the expedited charging user meets the preset conditions, otherwise it is determined that the expedited charging user does not meet the preset conditions; C. The preset power-off rule executed by the charging pile switching module is: calling the power-off duration data voluntarily selected by each user who is charging during this charging process from the user profile module, selecting the one with the largest value, and powering off the charging pile where the user is located; D. When the power-off time of the powered-off charging pile reaches the allowable power-off time during the current charging process and does not reach the expedited charging time required by the expedited charging user, the charging pile switching module repeats step C, selects another charging pile to power off, and restores power to the previously powered-off charging pile.

[0007] The beneficial effects of the present invention are as follows: since the qualification conditions are set for the users who require expedited charging, that is, they are required to provide the opportunity for themselves to be disconnected from the power supply in advance to ensure the expedited charging of others, so that they can obtain the right to request expedited charging, thereby avoiding the deliberate "cutting in" behavior; since the users who voluntarily provide the longest power-off time (whose charging needs are relatively unurgent) are preferentially disconnected, the loss caused to the users whose power is disconnected is minimized or even no actual loss is caused. Thus, the needs of users who require expedited charging are met, the fairness of the charging order is maintained, and a good atmosphere of mutual assistance among charging users is formed.
