Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In the related art, due to the influence of regional power supply power limitation, a parking lot supporting electric vehicle charging can only be provided with a limited number of charging piles, if an overload situation occurs due to the arrangement of excessive charging piles, the power utilization safety is influenced, and the increasing electric vehicle charging requirements cannot be met; simultaneously, fill electric pile place parking stall and also have the condition of being occupied by the fuel car, further obstructed the charging of electric motor car. In view of this, the present invention provides a dynamic charging pile allocation method, which can allocate charging piles by using a dynamic power allocation method and effectively limit the total power, so that any number of charging piles can be set, and the number of charging piles is ensured to meet the user requirements. Referring to fig. 1, fig. 1 is a flowchart of a method for dynamically allocating charging piles according to an embodiment of the present invention, where the method includes:
s101, receiving charging request information of the charging pile, extracting application power in the charging request information, and determining a charging pile group to which the charging pile belongs.
In the embodiment of the present invention, before the charging pile starts to perform charging, charging request information needs to be sent to a device for performing a charging pile dynamic allocation method in the embodiment of the present invention, so that the device performs dynamic allocation. It can be understood that, because the embodiment of the present invention utilizes the power of the charging pile to perform dynamic allocation, the charging request information at least should include the application power, which is the maximum power required by the charging pile to charge the electric vehicle. The embodiment of the present invention does not limit the specific form of the charging request information, and the embodiment of the present invention also does not limit other contents that can be included in the charging request information, for example, the present invention includes preset time period information indicating that charging is started in a specific time period, and may also include priority information indicating a charging priority, and the priority information may be set according to actual application requirements.
Further, in the embodiment of the invention, the charging pile group is adopted to perform centralized management on the charging piles. The embodiment of the present invention does not limit the number of charging piles that can be included in one charging pile group, and the number can be set arbitrarily. The number of charging piles that can be included in a charging area (e.g., a charging station) is not limited in the embodiments of the present invention, and may also be set according to practical application requirements, and it can be understood that at least one charging pile exists. In the embodiment of the invention, the dynamic allocation of the charging work of the charging piles is carried out by adopting the dynamic power allocation method, so that the total power of all the charging piles can be ensured not to exceed the power limit of a geographical area (such as a cell) where a charging area is located, the number of the charging piles can be set at will, and the number is not limited by the power of the geographical area. Referring to fig. 2, fig. 2 is a schematic diagram illustrating an arrangement of a charging pile and a centralized controller according to an embodiment of the present invention. The integrated controller is the device for performing the charging pile dynamic allocation method. In this region, original power can only set up 8 and fill electric pile (that is 8 that fill electric pile that grey region contains), and after having set up centralized control ware, this region can increase more and fill electric pile in order to satisfy the user demand.
S102, acquiring the real-time charging pile group power of the charging pile group, and calculating by using the applied power and the real-time charging pile group power to obtain the total power.
After the application power of the charging piles is obtained, in order to ensure that the total power of all the charging piles does not exceed the power limit of a geographical area, the real-time charging pile group power of the charging pile group is also obtained in the embodiment of the invention, and then the application power and the real-time charging pile group power are summed to obtain the total power of the charging piles corresponding to the allowable application power when the charging piles are charged.
It should be noted that the embodiment of the present invention does not limit the manner of obtaining the real-time charging pile group power, and for example, the device executing the dynamic distribution method of the charging piles sends a request message to each charging pile of the charging pile groups, and then the charging piles return the real-time charging pile power in a reply message manner, and finally the real-time charging pile power belonging to the same charging pile group is summed to obtain the real-time charging pile group power; of course, the real-time charging pile power can be sent to the device by the charging pile in real time, and the device monitors the real-time charging pile power of the charging pile group in real time. Considering that the latter method can not only rapidly acquire the real-time charging pile group power, but also monitor the overall working condition of the charging pile group, in the embodiment of the present invention, the acquisition method of the real-time charging pile group power may be: the real-time charging pile power is sent to the device by the charging pile in real time, and the real-time charging pile group power of the charging pile group is monitored by the device in real time.
Further, it is considered that there are a plurality of charging piles all of which need to be charged, that is, a plurality of charging piles all transmit charging request information. In order to ensure that the charging request information can be efficiently distributed according to a certain sequence, the charging request information can be added into a first-in first-out queue, and the charging request information at the head of the queue is dynamically distributed firstly, so that the charging request information which arrives firstly is processed firstly, and the charging request information which arrives later is processed later.
In a possible case, before calculating the total power by using the application power and the real-time charging pile group power, the method may further include:
step 11: and adding the charging request information to the queuing queue.
It should be noted that the embodiment of the present invention does not limit the specific form of the queue, and the queue may be a first-in first-out type queue, and may completely contain the content of the charging request information.
Correspondingly, the calculating of the total power by using the applied power and the real-time charging pile group power may include:
step 21: and setting the charging request information at the head of the queuing queue as the charging request information to be processed.
Step 22: and calculating to obtain total power by using the application power of the charging request information to be processed and the real-time charging pile group power.
S103, when the total power is larger than the preset power value, the step of obtaining the real-time charging pile group power of the charging pile group is continuously executed, and the total power is obtained through calculation by utilizing the application power and the real-time charging pile group power.
It should be noted that the preset power value is a preset power value corresponding to the charging pile group, and each charging pile group can be customized to set a corresponding preset power value. It will be appreciated that the sum of the preset power values for all the charging stake sets should be less than the power limit of the geographical area (e.g., cell) in which it is located. The embodiment of the invention limits the total power by adopting the preset power value, so that the total power of the charging pile group can be ensured not to exceed the power limit of a geographical area, and the power utilization safety can be further ensured.
It can be understood that, since the real-time charging pile group power of the charging pile group changes in real time, for example, the charging power of the charging pile group being charged decreases with time, or the charging pile group being charged completes charging, the determination operation of determining whether the total power is less than or equal to the preset power value is a loop, and the loop can be exited only when the total power is less than or equal to the preset power value. In order to reduce the calculation amount loss, the steps of obtaining the real-time charging pile group power of the charging pile group and calculating the total power by using the application power and the real-time charging pile group power are continuously executed, and the steps can be executed after the total power is judged to be larger than the preset power value and a preset time period is waited. It should be noted that, the embodiment of the present invention does not limit the specific value of the preset time period, and the user may perform the operation according to the actual application requirement.
And S104, when the total power is less than or equal to the preset power value, sending charging permission information to the charging pile so as to enable the charging pile to start charging.
When the total power is less than or equal to the preset power value, it can be understood that the charging pile in the charging pile group that is charging may end the charging task, or the charging power starts to be adjusted downward, and at this time, sufficient idle power exists in the charging pile group, and then the charging pile corresponding to the charging request information may be sent with charging permission information, so that the charging pile starts to charge.
It should be noted that the embodiment of the present invention does not limit the specific form of the charging permission information, and may include information for controlling the charging start of the charging pile. After the charging pile starts to charge, the charging state of the charging pile can be monitored, so that the real-time charging pile group power of the charging pile group can be rapidly determined.
Further, it can be understood that, when a queuing queue exists, the charging pile corresponding to the charging permission information is the charging pile corresponding to the charging request information located in the queuing queue.
Based on the embodiment, the method firstly requires the charging pile to send the charging request information containing the application power, dynamically distributes the application power by utilizing the real-time charging pile group power and the preset power value of the charging pile group, and sends the charging permission information to the charging pile only when the total power obtained by summing the real-time charging pile group power and the application power is less than or equal to the preset power value, so that the real-time charging pile group power can be effectively ensured to be kept within the preset power value, the overload condition is avoided, and the electricity safety can be effectively ensured; meanwhile, the method dynamically allocates the charging tasks of the charging piles and can effectively limit the total power, so that the number of the charging piles in the method can be set at will and is not limited by the regional power supply, a sufficient number of the charging piles can be set in a charging region for a power vehicle, and the influence of the fuel vehicle occupying the parking space where the charging piles are located on the charging of the power vehicle can be effectively relieved.
Based on the embodiment, considering that the user may urgently need to charge the electric vehicle, in order to ensure that the charging requirements of the user of the type are preferentially met, the priority can be set for the charging request information of the charging pile, and then dynamic allocation can be performed according to the priority of the charging pile. In order to solve the above technical problem, in a possible case, after extracting the application power in the charging request information and determining the charging pile group to which the charging pile belongs, the method may further include:
s201, when the charging request information contains priority information, searching the charging piles without priority in the charging piles being charged in the charging pile group.
In the embodiment of the present invention, the charging request information may further include priority information. It should be noted that, the embodiment of the present invention does not limit specific priority information, for example, the priority may include two types, i.e., a priority and a non-priority, and when the charging request information includes priority information, it indicates that the charging pile has the priority; of course, the priority level may be further subdivided into multiple levels, for example, the priority level may include one level, two levels, and three levels according to the priority order, and may be set according to the actual application requirement.
It can be understood that, when the priority is in a multi-level form, charging piles of which the levels are lower than the levels corresponding to the priority information can be queried in the charging piles according to the specific levels in the priority information.
S202, judging whether the real-time charging pile power of the charging pile without the priority is larger than or equal to the applied power; if not, go to step S203; if yes, the process proceeds to step S204.
In the embodiment of the invention, after the non-priority charging pile is determined, in order to ensure that the power does not exceed the limit, whether the real-time charging pile power corresponding to the non-priority charging pile is greater than or equal to the application power or not needs to be determined, and only when the real-time charging pile power is greater than or equal to the application power, the charging of the non-priority charging pile can be ensured to be stopped and the charging of the charging pile corresponding to the application power can be started, so that the power utilization safety can be ensured.
And S203, adding the charging request information to the head of the queuing queue.
When the real-time charging pile power of the non-priority charging pile cannot meet the power application requirement, the charging request information with the priority information can be added to the head of the queue, and therefore the charging request information with the priority is processed preferentially.
And S204, generating temporary request information containing the real-time charging pile power for the non-priority charging pile, and adding the temporary request information to the head of the queuing queue.
It is understood that the form of the temporary request information coincides with the form of the charging request information; simultaneously, in order to ensure that the non-priority charging pile can have the charging process that continues last time, the non-priority charging pile real-time charging pile power is stored in the temporary request information, so that the charging pile can continue the charging process according to the real-time charging pile power next time.
And S205, stopping charging of the charging piles without priority, and sending charging permission information to the charging piles corresponding to the charging request information.
It will be appreciated that the charging stop information may also be sent to the non-priority charging post to stop the charging process of the charging post.
Based on the embodiment, the priority information can be added into the charging request information, so that the priority charging requirement of the electric vehicle can be met, and the charging experience of the electric vehicle can be effectively improved.
Based on the above embodiment, in consideration of the fact that the user may require charging in a special time period, for example, the user requires charging in the early morning time period in order to save cost, in order to ensure that the charging requirements of the user are preferentially met, a preset time period may be set for the charging request information of the charging pile, and then dynamic allocation may be performed in the preset time period. In order to solve the above technical problem, in a possible case, after extracting the application power in the charging request information and determining the charging pile group to which the charging pile belongs, the method may further include:
s301, when the charging request information contains a preset time period, when the starting time corresponding to the preset time period is reached, the step of searching the charging pile without priority in the charging piles in the charging pile group is executed.
It should be noted that, the embodiment of the present invention does not limit the specific preset time period, and can be set according to the actual application requirement. It will be appreciated that the preset time period comprises a start time and an end time. Since the charging request information specifies that charging is to be performed within the preset time period, the charging request information can be dynamically allocated again when the start time of the preset time period is reached.
Further, after the charging pile corresponding to the charging request information containing the preset time period starts charging, the charging pile corresponding to the charging request information is stopped from charging when the preset time period end time is reached, so that the occurrence of poor user experience such as extra cost is avoided.
In one possible case, after sending the charging permission information to the charging post, the method further includes:
step 31: and when the end time of the preset time period is reached, stopping charging of the charging pile corresponding to the charging request information.
Based on the embodiment, the charging pile dynamic allocation method can perform charging pile dynamic allocation within the preset time period according to the preset time period in the charging request information, further meet the special requirement of charging within the special time period, and further improve the charging experience of the electric vehicle.
