Description

Technical Field

[0001] The embodiments of the present application relate to the technical field of electric vehicles, and specifically to a management method, device, equipment and computer-readable storage medium for electric vehicle charging reservations. Background Art

[0002] In the charging scenario of a new energy vehicle at a charging station, if the owner finds that there is no free charging position, he needs to make a reservation for the charging pile on the charging reservation system of the charging station. The current charging reservation system only supports the function of making reservations for charging piles that are in use. However, the existing charging reservation system does not take into account that not every charging pile needs to provide the reservation function. For example, for charging piles that are idle most of the time in a specific time period, there is no need to provide a reservation function. Therefore, the current charging reservation system cannot consider the actual situation of the charging pile to decide whether to open the reservation for the charging pile, which reduces the management efficiency of charging reservations.

[0003] In addition, the current charging reservation system only provides reservation functions for a single user. It cannot handle the situation where multiple car owners want to make reservations and queue up for the same charging pile, nor can it provide car owners with reminders of the waiting time in the queue. It cannot meet the reservation needs of multiple users, and the management efficiency of charging reservations is low. Summary of the invention

[0004] In view of the above problems, the embodiments of the present application provide a method, device, equipment and computer-readable storage medium for managing electric vehicle charging reservations, which are used to solve or partially solve the problem of low management efficiency of charging reservations in the prior art.

[0005] According to one aspect of an embodiment of the present application, a method for managing electric vehicle charging reservations is provided, the method comprising:

[0006] When receiving a charging reservation request from a target user, determining whether the target charging pile meets the reservation opening conditions;

[0007] The reservation opening condition is determined according to the utilization rate of the target charging pile, the date type of the day, and the usage status of the target charging pile;

[0008] If the target charging pile is in a reservation open state, the target user is written into the queue;

[0009] According to the time information of each user in the queue, the waiting time of the target charging pile is fed back to the target user.

[0010] Specifically, the present application comprehensively considers the actual usage of the charging piles through the utilization rate of the charging piles, the date type of the day, and the usage status of the charging piles, so as to decide whether to open the reservation of the charging piles, avoid idle charging piles occupying reservation resources, and improve the management efficiency of charging reservations.

[0011] At the same time, this application accepts charging reservations for charging piles that are open for reservation, queues the reservation users in the order of reservation, calculates the time information of each user in real time, and provides each reservation user with their own ranking and waiting time in the queue, thereby meeting the charging reservation and queuing needs of multiple users for the same charging pile, and improving the management efficiency of charging reservations.

[0012] In some optional ways, the determining whether the target charging pile meets the reservation opening condition includes:

[0013] When the utilization rate of the target charging pile within the preset number of days does not reach the preset utilization rate threshold, determining whether the target charging pile meets the reservation opening condition based on the date type of the day;

[0014] When the utilization rate of the target charging pile within a preset number of days reaches a preset utilization rate threshold, it is determined whether the target charging pile meets the reservation opening condition based on the usage status of the target charging pile.

[0015] Specifically, different from the prior art that only supports the function of making reservations for charging piles that are in use, the present application combines the utilization rate of the charging piles within a preset number of days and the date type of the day, or combines the utilization rate of the charging piles within a preset number of days and the usage status of the charging piles, and comprehensively considers the actual usage of the charging piles, so as to determine whether the charging piles meet the reservation opening conditions, avoid idle charging piles occupying reservation resources, and improve the management efficiency of charging reservations.

[0016] In some optional methods, before determining whether the target charging pile meets the reservation opening condition, the following steps are further included:

[0017] Based on the total charging time of each charging pile in the current charging station within a preset number of days, the entropy value and corresponding weight of each charging pile in several preset time periods are calculated;

[0018] Based on the entropy value of each charging pile in several preset time periods and the corresponding weight, a comprehensive score of each charging pile is obtained;

[0019] The average of the comprehensive scores of the charging piles in the current charging station is calculated, and the preset data is added to the average to obtain the utilization rate threshold of the target charging pile.

[0020] Specifically, this application calculates the entropy value and weight of each charging pile in the current charging station based on the entropy weight method, and then calculates the comprehensive score corresponding to each charging pile. This application uses the comprehensive score to set the utilization threshold of each charging pile as a reference for the utilization rate of the charging pile, and then combines the date type of the day or the usage status of the charging pile to determine the reservation opening conditions of the charging pile, so as to accurately identify the actual usage of the charging pile, further avoid idle charging piles occupying reservation resources, and improve the management efficiency of charging reservations.

[0021] In some optional ways, the waiting time of the target charging pile is fed back to the target user according to the time information of each user in the queue, specifically:

[0022] The remaining charging time of the first user in the queue is calculated in real time, and the waiting time of the non-first users in the queue is calculated in turn, so as to feed back the remaining charging time or waiting time of each user in the queue to the target user in real time.

[0023] Specifically, the present application accepts charging reservations made by users for charging piles that are open for reservation, queues the users in the order of reservation, calculates in real time the remaining charging time for the first-ranked user and the waiting time for users other than the first-ranked user, and provides each user with his or her ranking and waiting time in the queue, thereby satisfying the needs of multiple users for charging reservations and queuing for the same charging pile and improving the management efficiency of charging reservations.

[0024] In some optional manners, the real-time calculation of the remaining charging time of the user who is first in the queue includes:

[0025] Real-time acquisition of the first charging time of the vehicle connected to the target charging pile based on the current battery power feedback;

[0026] Based on the output power and the limited charging power of the target charging pile, as well as the battery capacity and the current battery power of the vehicle, a second charging time required for the vehicle to be charged to the limited charging power is calculated in real time;

[0027] According to the charging charging standard of the current time period and the pre-charging fee of the first user in the queue, the third charging time allowed for charging by the target charging pile based on the current remaining pre-charging fee is calculated in real time;

[0028] Among the first charging time, the second charging time and the third charging time, the minimum value is taken as the remaining charging time for the user who is first in the queue.

[0029] Specifically, for the vehicle connected to the target charging pile, that is, the first user in the queue, this application comprehensively considers the limitation of the vehicle battery power, the charging limitation of the target charging pile, and the limitation of the vehicle pre-charging fee, calculates three corresponding charging times in real time, and takes the minimum value as the remaining charging time of the target user who ranks first in the queue. This application provides real-time feedback on the remaining charging time of the target user who ranks first in the queue, and provides an accurate waiting time for subsequent reservation users, so that subsequent reservation users can calculate their respective rankings and waiting times in the queue, meet the needs of multiple users for charging reservations and queuing for the same charging pile, and improve the management efficiency of charging reservations.

[0030] In some optional manners, the waiting time of the users not in the first position in the queue is calculated in sequence, including:

[0031] Based on the estimated end time of the first user, determine the starting charging period of the target charging pile where the second user falls;

[0032] The second user is any user who is not the first user in the queue, and the first user is the user who is one user before the second user in the queue;

[0033] According to each charging period of the target charging pile and the corresponding average deduction rate, combined with the pre-charging fee of the second user and the starting charging period, the estimated charging time of the second user in each charging period is obtained;

[0034] The waiting time of the second user is obtained by adding the sum of the estimated charging time of the second user in each charging period to the estimated end time of the first user.

[0035] Specifically, charging piles have different charging standards in different charging periods, and each charging period corresponds to an average deduction rate. Therefore, this application can determine the estimated end time of the first user based on the remaining charging time of the first user in the queue, so as to determine the starting charging period for the second user in the queue, and determine the charging time and waiting time of the second user in combination with the average deduction rate corresponding to each charging period and the pre-charge fee of the second user. By analogy, this application calculates the waiting time of each second user in the queue in turn for real-time feedback, and provides users with the remaining charging time of the target user who ranks first in the queue, as well as the ranking and waiting time of the second user who ranks second in the queue, so as to meet the needs of multiple users for charging reservations and queuing for the same charging pile, and improve the management efficiency of charging reservations.

[0036] In some optional methods, before any third user uses the target charging pile, if a charging reservation cancellation request is received from the third user, the third user will be deleted from the queue, and the pre-charging fee of the third user will be managed according to the time when the third user submits the charging reservation cancellation request.

[0037] Specifically, the present application imposes a time limit on the time within which a user may request to cancel a charging reservation before using a charging pile. When a user does not cancel a charging reservation within the specified time frame, a corresponding fee will be deducted from the pre-charging fee based on the time when the request to cancel the charging reservation is submitted, thereby avoiding waste of charging resources due to temporary cancellation by the user and improving the management efficiency of charging reservations.

[0038] In some optional ways, if the vehicle connected to the target charging pile does not release the charging pile within a third time range after completing charging, a target fee is charged to the user to whom the vehicle connected to the target charging pile belongs based on the time exceeding the third time range until the vehicle connected to the target charging pile releases the charging pile;

[0039] If there are users in the queue, the target fee is allocated to the accounts corresponding to the users in the queue according to a preset ratio.

[0040] Specifically, the present application limits the time for users to release the charging pile after using it. If the user does not release the charging pile in time after the vehicle is charged, it is necessary to charge the user of the vehicle connected to the target charging pile based on the time exceeding the third time range, and distribute the target fee to users in the queue according to a preset ratio to avoid users occupying charging resources and compensate the affected users, thereby improving the management efficiency of charging appointments.

[0041] According to another aspect of an embodiment of the present application, there is provided a management device for electric vehicle charging reservation, comprising: a reservation module and a queuing module;

[0042] The reservation module is used to determine whether the target charging pile meets the reservation opening conditions when receiving a reservation charging request from a target user;

[0043] The reservation opening condition is determined according to the utilization rate of the target charging pile, the date type of the day, and the usage status of the target charging pile;

[0044] The queuing module is used to write the target user into a queuing queue if the target charging pile is in a reservation open state; and to feed back the waiting time of the target charging pile to the target user according to the time information of each user in the queuing queue.

[0045] According to another aspect of an embodiment of the present application, a management device for electric vehicle charging reservations is provided, comprising: a processor, a memory, a communication interface and a communication bus, wherein the processor, the memory and the communication interface communicate with each other via the communication bus; the memory is used to store at least one executable instruction, and the executable instruction enables the processor to perform the operation of the electric vehicle charging reservation management method as described in any one of the above.

[0046] According to another aspect of an embodiment of the present application, a computer-readable storage medium is provided, wherein at least one executable instruction is stored in the storage medium, and the executable instruction enables an electric vehicle charging reservation management device / apparatus to perform the operation of the electric vehicle charging reservation management method as described in any one of the above.

[0047] The embodiment of the present application comprehensively considers the actual use of the charging pile through the utilization rate of the charging pile, the date type of the day, and the use status of the charging pile, so as to decide whether to open the reservation of the charging pile, avoid idle charging piles occupying reservation resources, and improve the management efficiency of charging reservation. At the same time, the embodiment of the present application accepts the charging reservation of the reserved user for the charging pile that is open for reservation, queues the reserved users in the order of reservation, calculates the time information of each user in the queue in real time, and provides each reserved user with their own ranking and waiting time in the queue, so as to meet the needs of multiple users for charging reservation and queuing for the same charging pile, and improve the management efficiency of charging reservation. In addition, the embodiment of the present application limits the time when the user submits a request to cancel the charging reservation before using the charging pile, and the time when the charging pile is released after using the charging pile, so as to avoid wasting charging resources and improve the management efficiency of charging reservation.

[0048] The above description is only an overview of the technical solution of the embodiment of the present application. In order to more clearly understand the technical means of the embodiment of the present application, it can be implemented in accordance with the contents of the specification.

[0055] The exemplary embodiments of the present application will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present application are shown in the drawings, it should be understood that the present application can be implemented in various forms and should not be limited by the embodiments set forth herein.

[0056] Figure 1 The flowchart of an embodiment of the method for managing electric vehicle charging reservations of the present application is shown, and the method is executed by a management device for electric vehicle charging reservations. Figure 1 As shown, the method comprises the following steps:

[0057] Step 110: When receiving a charging reservation request from a target user, determine whether the target charging pile is in a reservation open state.

[0058] Specifically, the management device manages the reservation of all charging piles in the charging station. When the charging pile meets the reservation opening condition, the management device sets the reservation state of the charging pile meeting the reservation opening condition to the reservation opening state.

[0059] Preferably, the management device sets the initial value of the reservation status of the charging pile to the closed state. When the management device receives the reservation charging request of the first reservation user, it determines whether the target charging pile meets the reservation opening condition. If the target charging pile meets the reservation opening condition, the reservation status of the charging pile is set to the reservation opening state. When the management device receives the reservation charging request of a user other than the first reservation user, it is not necessary to determine whether the target charging pile meets the reservation opening condition.

[0060] Step 120: If the target charging pile is in a reservation open state, or if the target charging pile is not in a reservation open state and the target charging pile meets the reservation open condition, the target user is written into the queue; wherein the reservation open condition is determined according to the utilization rate of the target charging pile, the date type of the day, and the usage status of the target charging pile.

[0061] In some embodiments of the present application, the step of determining whether the target charging pile meets the reservation opening condition includes:

[0062] When the utilization rate of the target charging pile within the preset number of days does not reach the preset utilization rate threshold, determining whether the target charging pile meets the reservation opening condition based on the date type of the day;

[0063] When the utilization rate of the target charging pile within a preset number of days reaches a preset utilization rate threshold, it is determined whether the target charging pile meets the reservation opening condition based on the usage status of the target charging pile.

[0064] Specifically, when the utilization rate does not reach the utilization rate threshold and the date type of the day is a preset type, or when the utilization rate reaches the utilization rate threshold and a vehicle is being charged at the target charging pile, it is determined that the target charging pile meets the reservation opening condition.

[0065] Preferably, please refer to Figure 2 The charging station regularly counts the utilization rate of each charging pile. The management device obtains the utilization rate of the target charging pile and compares the utilization rate of the target charging pile with the utilization rate threshold. Among them, the utilization rate of the target charging pile within the preset number of days is the ratio of the total charging time of the target charging pile within the preset number of days to the total duration of the preset number of days.

[0066] If the utilization rate of the target charging pile does not reach the utilization rate threshold, the management device determines whether the date type of the day is a statutory holiday such as a holiday. If the date type of the day is a statutory holiday such as a holiday, the management device determines that the target charging pile does not meet the reservation opening condition and does not open the reservation function of the target charging pile.

[0067] When the utilization rate of the target charging pile reaches the utilization rate threshold, or when the utilization rate of the target charging pile does not reach the utilization rate threshold and the date type of the day is not a statutory holiday such as a holiday, the management device detects whether there is a vehicle charging at the target charging pile.

[0068] If no vehicle is being charged at the target charging pile, the management device determines that the target charging pile does not meet the reservation opening condition, and does not open the reservation function of the target charging pile.

[0069] If a vehicle is being charged at the target charging pile, the management device determines that the target charging pile meets the reservation opening condition and opens the reservation function of the target charging pile.

[0070] When the management device determines that the target charging pile meets the reservation opening conditions, it opens the reservation function of the target charging pile and receives the charging reservations of the reserved users in turn for charging reservations. After the previous reserved user successfully makes a reservation, the next reserved user is allowed to make a reservation until the number of reserved users reaches N. N is the maximum number of reserved users set by the charging station. When the number of reserved users reaches N, the management device closes the reservation function of the target charging pile and does not allow the reservation function to be released to more users.

[0071] Preferably, when the management device receives a charging reservation from a subscribing user, it charges the subscribing user a pre-charging fee, and the amount of the pre-charging fee is set by the subscribing user according to charging requirements.

[0072] Different from the prior art that only supports the function of making reservations for charging piles that are being used, the embodiments of the present application combine the utilization rate of the charging piles within a preset number of days and the date type of the day, or combine the utilization rate of the charging piles within a preset number of days and the usage status of the charging piles, and comprehensively consider the actual usage of the charging piles, so as to determine whether the charging piles meet the reservation opening conditions, avoid idle charging piles occupying reservation resources, and improve the management efficiency of charging reservations.

[0073] In some embodiments of the present application, before determining whether the target charging pile is in a reservation open state, the method further includes:

[0074] Based on the total charging time of each charging pile in the current charging station within a preset number of days, the entropy value and corresponding weight of each charging pile in several preset time periods are calculated;

[0075] Based on the entropy value of each charging pile in several preset time periods and the corresponding weight, a comprehensive score of each charging pile is obtained;

[0076] The average of the comprehensive scores of the charging piles in the current charging station is calculated, and the preset data is added to the average to obtain the utilization rate threshold of the target charging pile.

[0077] Specifically, the management device periodically selects the charging time of the charging piles in a preset time period, and recalculates the utilization threshold of each charging pile to dynamically adjust the reservation opening conditions of the charging piles.

[0078] Preferably, the management device regularly selects the charging time of the charging pile in the first week of each month, divides the days of the first week into k time periods, and takes the ratio of the charging time of the i-th charging pile in the j-th time period to the total charging time of all charging piles in the j-th time period as the normalized value of the i-th charging pile in the j-th time period to eliminate the influence of the dimension. The normalization formula is:

[0079]

[0080] Among them, X ij is the standardized value of the i-th charging pile in the j-th time period, x ij is the charging time of the i-th charging pile on the j-th day, m is the total number of charging piles in the charging station, m, i, j and k are positive integers; k is greater than or equal to j; m is greater than or equal to i.

[0081] The management device calculates the entropy value of each time period according to the standardized value of each charging pile in each time period and the number of the charging piles; the calculation formula of the entropy value is:

[0082]

[0083] Among them, E j is the entropy value of the jth time period, which is used to measure the uncertainty or diversity of information; n is the number of charging time data corresponding to each charging pile in a certain time period; p ij is the standardized value of the ith charging pile in the jth time period, that is, the proportion of the charging time of the charging pile in this time period to the total charging time of all charging piles in this time period; ln is a natural logarithm function, which can transform the numerical value into an information measurement form that is more suitable for calculation.

[0084] The management device calculates the weight of each time period based on the entropy value of each time period; the weight w of the jth time period j The calculation formula is:

[0085]

[0086] The standardized value of each charging pile in each time period is multiplied by the weight of the corresponding time period and then added to obtain the comprehensive score of each charging pile; the calculation formula for the comprehensive score of the i-th charging pile is:

[0087]

[0088] The average of the comprehensive scores of each charging pile in the current charging station is calculated, and 3 sigma is added to the average to obtain the utilization threshold of each charging pile.

[0089] The embodiment of the present application calculates the entropy value and weight of each charging pile in the current charging station based on the entropy weight method, and then calculates the comprehensive score corresponding to each charging pile. The present application uses the comprehensive score to set the utilization threshold of each charging pile as a reference for the utilization rate of the charging pile, and then combines the date type of the day or the usage status of the charging pile to determine the reservation opening conditions of the charging pile, so as to accurately identify the actual usage of the charging pile, further avoid idle charging piles occupying reservation resources, and improve the management efficiency of charging reservations.

[0090] Step 130: Feedback the waiting time of the target charging pile to the target user based on the time information of each user in the queue.

[0091] In some embodiments of the present application, the waiting time of the target charging pile is fed back to the target user according to the time information of each user in the queue, specifically:

[0092] The remaining charging time of the first user in the queue is calculated in real time, and the waiting time of the non-first users in the queue is calculated in turn, so as to feed back the remaining charging time or waiting time of each user in the queue to the target user in real time.

[0093] Preferably, please refer to Figure 3 , is the queue interface displayed on the user APP when the first user who made a reservation is using the target charging pile. The queue interface displays the names of the first to n users in the order of the queue and the corresponding waiting time. Among them, n is the number of users who made reservations. The queue interface displays the remaining time for the first user to charge the vehicle using the target charging pile, as well as the average waiting time of the second to nth users who made reservations.

[0094] In some embodiments of the present application, the real-time calculation of the remaining charging time of the first user in the queue includes:

[0095] Real-time acquisition of the first charging time of the vehicle connected to the target charging pile based on the current battery power feedback;

[0096] Based on the output power and the limited charging power of the target charging pile, as well as the battery capacity and the current battery power of the vehicle, a second charging time required for the vehicle to be charged to the limited charging power is calculated in real time;

[0097] According to the charging charging standard of the current time period and the pre-charging fee of the first user in the queue, the third charging time allowed for charging by the target charging pile based on the current remaining pre-charging fee is calculated in real time;

[0098] Among the first charging time, the second charging time and the third charging time, the minimum value is taken as the remaining charging time for the user who is first in the queue.

[0099] Preferably, the current battery power of the vehicle is subtracted from the limited charging power to obtain a power difference; the power difference is multiplied by the battery capacity and divided by the output power of the target charging pile to obtain a second charging time required for the vehicle to charge to the limited charging power.

[0100] According to the charging charge standard of the current time period, calculate the cost and time required to charge a preset amount of electricity; subtract the cost required to charge the preset amount of electricity from the remaining charging cost of the vehicle to obtain the remaining cost; multiply the remaining cost by the time required to charge the preset amount of electricity, and divide it by the cost required to charge the preset amount of electricity to obtain the third charging time allowed for charging by the target charging pile based on the current remaining pre-charging cost.

[0101] Assume that the output power of the target charging pile is x KW, the target charging pile obtains SOC=z at the start time of charging, the capacity of the vehicle battery is y KWH, and the charging pile restricts the vehicle battery from being fully charged and only allows charging to SOC=k.

[0102] If a charging gun of a charging pile is used to charge the vehicle, the calculation expression for the second charging time n (hours) required for the vehicle to charge to the limited charging power is:

[0103]

[0104] If the vehicle is charged using two charging guns of the charging pile, the calculation expression for the second charging time required for the vehicle to charge to the limited charging power is:

[0105]

[0106] The management device takes the minimum time L=min(m, n) of the first charging time m and the second charging time n as the remaining charging time calculated without considering the cost.

[0107] Assume that the pre-charging fee for this charging is a, the fee required to charge the vehicle to 5% SOC is h, and the time required to charge the vehicle to 5% SOC is b hours;

[0108] The calculation expression of the third charging time D (hours) allowed for charging by the target charging pile based on the current remaining pre-charging fee is:

[0109]

[0110] The management device takes the minimum time min(L, D) of the remaining charging time L without considering the cost and the third charging time D as the remaining charging time considering the cost, and updates the D value in real time according to the charging cost and charging time for charging the vehicle to 5% SOC.

[0111] The remaining charging time taking into account the cost will be fed back to the user's APP in real time as the remaining charging time for the first user in the queue.

[0112] For the vehicle connected to the target charging pile, that is, the user ranked first in the queue, the embodiment of the present application comprehensively considers the limitation of the vehicle battery power, the charging limitation of the target charging pile, and the limitation of the vehicle pre-charging fee, and calculates the remaining charging time considering the fee in real time as the remaining charging time of the target user ranked first in the queue. The embodiment of the present application provides real-time feedback on the remaining charging time of the target user ranked first in the queue, and provides an accurate waiting time for subsequent reservation users, so that subsequent reservation users can calculate their respective rankings and waiting times in the queue, meet the needs of multiple users for charging reservations and queuing for the same charging pile, and improve the management efficiency of charging reservations.

[0113] In some embodiments of the present application, sequentially calculating the waiting time of users who are not the first in the queue includes:

[0114] Based on the estimated end time of the first user, determine the starting charging period of the target charging pile where the second user falls;

[0115] The second user is any user who is not the first user in the queue, and the first user is the user who is one user before the second user in the queue;

[0116] According to each charging period of the target charging pile and the corresponding average deduction rate, combined with the pre-charging fee of the second user and the starting charging period, the estimated charging time of the second user in each charging period is obtained;

[0117] The waiting time of the second user is obtained by adding the sum of the estimated charging time of the second user in each charging period to the estimated end time of the first user.

[0118] Specifically, the target charging pile is provided with different charging periods, and different charging standards are provided in different charging periods. The management device counts the historical deduction records of the target charging pile in each charging period to obtain the average deduction rate of each charging period of the target charging pile. For example, in the historical deduction records of the first charging period, there are several users who use the target charging pile to charge, and different users have different deduction rates. The average of the deduction rates of all users who use the target charging pile in the first charging period is calculated as the average deduction rate of the first charging period.

[0119] According to the estimated end time of the last user in the queue, it is determined that the starting charging period that the current user falls into is the second charging period.

[0120] The pre-charge fee of the current user is divided by the average deduction rate corresponding to the second charging period to obtain the first time. The estimated end time of the previous user is added to the first time to obtain the estimated second time in the second charging period.

[0121] Determine the usage time T1 in the second charging period. The calculation expression of T1 is:

[0122] T1=t1-(t0+5).

[0123] Among them, t1 is the end time of the second charging period, and t0 is the estimated end time of the previous user.

[0124] If the second time exceeds the second charging period, the third charging period next to the second charging period is entered, and the third time t3 estimated in the third charging period is calculated. The calculation expression of t3 is:

[0125]

[0126] Among them, s1 is the average deduction rate of the second charging period, s2 is the average deduction rate of the third charging period, and a is the pre-charge fee of the current user.

[0127] If the third time does not exceed the end time of the third charging period, the third time is used as the usage time T2 in the third charging period, and the waiting time of the second user T3=t0+T1+T2.

[0128] If the third time exceeds the end time of the third charging period, the fourth time expected in the next fourth charging period and the usage time of the fourth charging period continue to be calculated until the usage time of the second user in each of the charging periods is calculated.

[0129] The waiting time of the second user is obtained by adding the total usage time of the second user in each charging period to the estimated end time of the first user.

[0130] The embodiment of the present application can determine the estimated end time of the first user based on the remaining charging time of the first user in the queue, so as to determine the starting charging period for the second user in the queue, and determine the charging time and waiting time of the second user in combination with the average deduction rate corresponding to each charging period and the pre-charge fee of the second user. By analogy, the present application calculates the waiting time of each second user in the queue in turn and provides real-time feedback, providing users with the remaining charging time of the target user in the first place in the queue, as well as the ranking and waiting time of the second user who is not in the first place in the queue, so as to meet the needs of multiple users for charging reservations and queuing for the same charging pile, and improve the management efficiency of charging reservations.

[0131] In some embodiments of the present application, before any third user uses the target charging pile, if a charging reservation cancellation request is received from the third user, the third user will be deleted from the queue, and the pre-charging fee of the third user will be managed according to the time when the third user submits the charging reservation cancellation request.

[0132] Specifically, if the time when the third user submits the charging reservation cancellation request exceeds the first time range, the management device determines whether the current waiting time of the third user is greater than the second time range;

[0133] The first time range is obtained by adding the reservation time of the third user to the preset time range;

[0134] If the current waiting time of the third user is greater than the second time range, the management device does not deduct fees;

[0135] If the current waiting time of the third user is less than or equal to the second time range, the management device deducts part or all of the pre-charge fee of the third user based on the time exceeding the first time range.

[0136] Preferably, the management device deducts the pre-charge fee of the third user according to a preset proportion of the time exceeding the first time range until the maximum limit is reached, or until all the pre-charge fees are deducted.

[0137] The embodiment of the present application limits the time for a user to submit a request to cancel a charging reservation before using a charging pile. The user submits a request to cancel a charging reservation after exceeding a first time range, and the user's current waiting time is less than or equal to a second time range. The management device needs to deduct the corresponding fee from the pre-charging fee based on the time exceeding the first time range, thereby avoiding waste of charging resources due to temporary cancellation by the user and improving the management efficiency of charging reservations.

[0138] In some embodiments of the present application, if the vehicle connected to the target charging pile does not release the charging pile within a third time range after completing charging, the target fee is charged to the user to whom the vehicle connected to the target charging pile belongs based on the time exceeding the third time range until the vehicle connected to the target charging pile releases the charging pile;

[0139] If there are users in the queue, the target fee is allocated to the accounts corresponding to the users in the queue according to a preset ratio.

[0140] Preferably, if the user does not release the charging pile in time after the vehicle is charged, a parking fee will be charged to the user whose vehicle is connected to the target charging pile based on the time exceeding the third time range, and the fee will be distributed to the users in the queue and the charging pile company according to a preset ratio.

[0141] If a user in the queue cancels his charging reservation, the occupancy fee attributable to the user will stop being charged from the moment the charging reservation is canceled.

[0142] This application limits the time for users to release the charging pile after using it. If the user does not release the charging pile in time after the vehicle is charged, it is necessary to charge the user of the vehicle connected to the target charging pile a space fee based on the time exceeding the third time range, so as to avoid users occupying charging resources and compensate the affected users, thereby improving the management efficiency of charging appointments.

[0143] Figure 4 The structure diagram of the first embodiment of the management device for electric vehicle charging reservation of the present application is shown; Figure 4 As shown, the device 400 includes: a reservation module 410 and a queuing module 420;

[0144] The reservation module 410 is used to determine whether the target charging pile meets the reservation opening conditions when receiving the target user's reservation charging request;

[0145] The reservation opening condition is determined according to the utilization rate of the target charging pile, the date type of the day, and the usage status of the target charging pile;

[0146] The queuing module 420 is used to write the target user into a queuing queue if the target charging pile is in a reservation open state; and to feed back the waiting time of the target charging pile to the target user according to the time information of each user in the queuing queue.

[0147] In some optional embodiments, the reservation module 410 includes: a threshold calculation unit and a judgment unit.

[0148] In some optional embodiments, the threshold calculation unit is used to calculate the entropy value and corresponding weight of each charging pile in a number of preset time periods based on the total charging time of each charging pile in the current charging station within a preset number of days;

[0149] Based on the entropy value of each charging pile in several preset time periods and the corresponding weight, a comprehensive score of each charging pile is obtained;

[0150] The average of the comprehensive scores of the charging piles in the current charging station is calculated, and the preset data is added to the average to obtain the utilization rate threshold of the target charging pile.

[0151] In some optional modes, the judgment unit is used to determine whether the target charging pile meets the reservation opening condition based on the date type of the day when the utilization rate of the target charging pile within the preset number of days does not reach the preset utilization rate threshold;

[0152] When the utilization rate of the target charging pile within a preset number of days reaches a preset utilization rate threshold, it is determined whether the target charging pile meets the reservation opening condition based on the usage status of the target charging pile.

[0153] In some optional methods, the queuing module 420 is used to calculate in real time the remaining charging time of the user ranked first in the queue, and calculate the waiting time of the users not ranked first in the queue in turn, so as to provide real-time feedback to the target user on the remaining charging time or waiting time of each user in the queue.

[0154] In some optional embodiments, the queuing module 420 includes a first time calculation unit and a second time calculation unit;

[0155] In some optional modes, the first time calculation unit is used to obtain in real time the first charging time of the vehicle connected to the target charging pile based on the current battery power feedback;

[0156] Based on the output power and the limited charging power of the target charging pile, as well as the battery capacity and the current battery power of the vehicle, a second charging time required for the vehicle to be charged to the limited charging power is calculated in real time;

[0157] According to the charging charging standard of the current time period and the pre-charging fee of the first user in the queue, the third charging time allowed for charging by the target charging pile based on the current remaining pre-charging fee is calculated in real time;

[0158] Among the first charging time, the second charging time and the third charging time, the minimum value is taken as the remaining charging time for the user who is first in the queue.

[0159] In some optional manners, the second time calculation unit is used to sequentially calculate the waiting time of users who are not the first in the queue, including:

[0160] Based on the estimated end time of the first user, determine the starting charging period of the target charging pile where the second user falls;

[0161] The second user is any user who is not the first user in the queue, and the first user is the user who is one user before the second user in the queue;

[0162] According to each charging period of the target charging pile and the corresponding average deduction rate, combined with the pre-charging fee of the second user and the starting charging period, the estimated charging time of the second user in each charging period is obtained;

[0163] The waiting time of the second user is obtained by adding the sum of the estimated charging time of the second user in each charging period to the estimated end time of the first user.

[0164] In some optional modes, the electric vehicle charging reservation management device further includes: a fee management module. The fee management module includes a timeout cancellation unit and a timeout placeholder unit;

[0165] The timeout cancellation unit is used to receive a charging reservation cancellation request from a third user before any third user uses the target charging pile, and then delete the third user from the queue, and manage the pre-charging fee of the third user according to the time when the third user submits the charging reservation cancellation request.

[0166] The timeout placeholder unit is used to charge the target fee to the user of the vehicle connected to the target charging pile based on the time exceeding the third time range if the vehicle connected to the target charging pile does not release the charging pile within a third time range after completing charging, until the vehicle connected to the target charging pile releases the charging pile;

[0167] If there are users in the queue, the target fee is allocated to the accounts corresponding to the users in the queue according to a preset ratio.

At the same time, the embodiment of the present application accepts the charging reservation of the reserved user for the open reserved charging pile through the queuing module, queues the reserved users in the order of reservation, calculates the time information of each user in the queue in real time, and provides each reserved user with their own ranking and waiting time in the queue, so as to meet the needs of multiple users for charging reservation and queuing of the same charging pile, and improves the management efficiency of charging reservation. In addition, the embodiment of the present application limits the time when the user submits a request to cancel the charging reservation before using the charging pile, and the time when the charging pile is released after using the charging pile, so as to avoid wasting charging resources and improve the management efficiency of charging reservation.
