Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of new energy vehicle charging, in particular to a peak-shaving charging regulation method, a charging pile system, a control device and a storage medium. BACKGROUND

[0002] New energy vehicles gradually enter every household, and more and more cluster charging piles form a charging pile system in cities. The charging piles can charge vehicles after converting the power supply.

[0003] For large-scale cities, especially in summer, the power load of the city is very large. Therefore, in the power supply planning of the power supply bureau for the city, during the peak power consumption period, each district is required to rotate peak power consumption. The district required to consume low-voltage power needs to cooperate to reduce power consumption. This requirement may be planned time or may be sudden. Therefore, most of the existing charging piles are equipped with energy storage modules such as batteries or super capacitors. During the standby period of low peak power consumption and no vehicle charging, the energy storage module can be used to store power. During the peak power consumption period, the energy storage module can also be used to charge the vehicle.

[0004] However, in the existing charging pile safety regulations, it is usually prohibited that the energy storage module charges the vehicle at the same time as the power supply charges the energy storage module, and when in the peak power consumption period, the charging pile system can only allow a limited number (peak queue number) of charging piles to charge at the same time. For a vehicle that needs to be charged for 200 degrees, when entering the charging pile system to select a charging pile, although the current may be in the low peak power consumption period, it cannot be determined when the peak power consumption period will be implemented. The energy storage module cannot meet the charging condition of the charging pile with 200 degrees of stored power. The user selects the charging pile that does not meet the charging condition to charge, and when the vehicle is not fully charged and the peak power consumption period occurs, the charging pile is limited to obtain power from the power supply. The user cannot know when the vehicle can obtain the required power, resulting in unreliable charging conditions, and even the user needs to change the charging pile on site. SUMMARY

[0005] The present application aims to at least solve one of the technical problems existing in the prior art. To this end, the present application proposes a peak-shaving charging regulation method, a charging pile system, a control device and a storage medium, which push reliable charging data to users in the peak-shaving power consumption scenario, so as to facilitate users to select charging piles as needed and properly arrange time.

The input end of the discharging switch module is connected with the first energy storage module and the second energy storage module. The output end of the discharging switch module is connected with a plug-in connector. Each charging pile device comprises at least a first charging state and a second charging state. In the first charging state, the discharging switch module makes the first energy storage module conductive with the plug-in connector and the second energy storage module disconnected with the plug-in connector. The charging switch module makes the mains conductive with the second energy storage module and disconnected with the first energy storage module.

[0039] It should be noted that the charging pile system is arranged in an open-air parking lot or a floor parking lot of a shopping mall, an office building, etc., the charging pile devices 100 are distributed at various positions of the parking lot, the monitoring device 200 can include a cloud server 210 and a central processor 220, the cloud server 210 can be connected in communication with the control terminal of the vehicle through a mobile communication network, and the central processor 220 is respectively connected with each charging pile device 100 and the cloud server 210.

[0041] As shown in Figs. 3-4 The peak-shaving charging regulation method comprises the following steps:

[0042] S310, obtaining a vehicle charging request, wherein the vehicle charging request comprises a required electric quantity of a vehicle;

[0043] S320, checking each standby charging pile device 100 according to the vehicle charging request to determine whether the charging pile meets the charging condition of the vehicle. The standby charging pile device 100 is a charging pile device 100 that does not charge the vehicle. The checking of the charging pile device 100 according to the vehicle charging request comprises the following steps:

[0044] S410, obtaining a first storage electric quantity of the first energy storage module 110 and a second storage electric quantity of the second energy storage module 120;

[0045] S420, when the first storage electric quantity is greater than the required electric quantity of the vehicle, marking the charging pile device 100 as a first-class charging pile that meets the charging condition of the vehicle;

[0046] S430, when the first storage electric quantity is less than the required electric quantity of the vehicle, calculating the difference between the required electric quantity of the vehicle and the first storage electric quantity to obtain a supplementary charging quantity;

[0047] S440, calculating a first charging time according to the supplementary charging quantity, the second storage electric quantity, and the charging speed of the charging pile;

[0048] S450, when the first charging time is less than or equal to the peak-shifting allowance time threshold, the charging pile device 100 is marked as a second charging pile that meets the charging condition of the vehicle;

[0049] S460, calculating the estimated longest charging time of the second charging pile, wherein the number of the second charging piles being charged and the corresponding first charging time are counted, and the estimated longest charging time of the second charging pile is calculated according to the peak queue number, the number of the second charging piles being charged, the first charging time of each second charging pile being charged, and the first charging time of the second charging pile; the peak queue number is the number of the second energy storage modules 120 allowed to be charged by the power grid in the charging pile system during the power consumption peak period;

[0050] S330, sending the parameter data of each standby first charging pile and the parameter data of each standby second charging pile to the vehicle sending the vehicle charging request, wherein the parameter data of the first charging pile includes the position information of the first charging pile, and the parameter data of the second charging pile includes the position information of the second charging pile and the corresponding estimated longest charging time.

[0051] Wherein, the vehicle can send a vehicle charging request to the cloud server 210 when entering the parking lot, wherein the required power of the vehicle can be calculated from the total storage capacity of the vehicle and the remaining power of the vehicle, or can be set by the user.

[0052] And the charging pile device 100 is provided with the first energy storage module 110 and the second energy storage module 120, and in the process of executing the peak-shifting charging regulation method, the one with higher storage capacity is taken as the first energy storage module 110, and the one with lower storage capacity is taken as the second energy storage module 120.

[0053] In addition, in step S330, the user can obtain the parameter data from the vehicle, and the user can know the positions of the first charging pile and the second charging pile. The number of the first charging pile is small, and the distance from the vehicle at this time can be far, while the number of the second charging pile is large, and the user can select as needed, and can send a binding instruction to the selected charging pile through the vehicle, and match the charging after the vehicle travels to the corresponding charging pile.

[0054] It can be understood that the peak-shifting allowance time threshold is the longest time allowed for the power grid to charge the second energy storage module 120 in the second charging pile when entering the power consumption peak period. This peak-shifting allowance time threshold can be set by the manufacturer or specified by the power supply department, so as to guarantee the reasonable planning of urban peak-shifting power consumption and reduce the urban power consumption load. The charging speed of the charging pile is set as the actual speed of the power grid charging the charging pile.

[0055] In the calculation of the estimated longest charging time of the second-class charging pile, since in most cases, it is not possible to accurately know when to enter the peak electricity consumption period, it is assumed that the current time is in the peak electricity consumption period, and even if the second energy storage module 120 of part of the second-class charging pile has been charged for a certain period of time, the first charging time is still used to calculate in step S460. In addition, since it is assumed that the current time is in the peak electricity consumption period in the estimation, each second-class charging pile is immediately calculated to enter the peak charging queue, so that the estimated longest charging time is provided to the user. However, in the subsequent actual charging process, it is possible to be in the off-peak electricity consumption period all the time, and the estimated longest charging time can be greatly shortened. The actual charging time will be less than the estimated longest charging time. Since the user has been provided with the reference of the estimated longest charging time, the substantial reduction of the actual charging time can also meet the user's requirements.

[0056] The peak-shifting charging regulation method of the application, at least the first energy storage module 110 and the second energy storage module 120 in the charging pile device 100, the second energy storage module 120 can be charged by the mains while the first energy storage module 110 is charging the vehicle, saving time and ensuring the safety of charging,

[0057] When the user drives the vehicle into the place where the charging pile system is located to select the charging pile for charging, the vehicle charging request will be sent to the monitoring device 200 first. After receiving the vehicle charging request, the monitoring device 200 can traverse and detect whether each standby charging pile device 100 meets the charging conditions of the vehicle. If the first storage capacity in part of the charging pile device 100 is already greater than the required capacity of the vehicle, it means that even if the mains does not charge the second energy storage module 120, the charging pile device 100 can still meet the required capacity of the vehicle. Therefore, the charging pile device 100 can be directly marked as a first-class charging pile. However, considering the situation that the number of first-class charging piles may not be large and the distance between the first-class charging piles and the user's vehicle may be far, the design also provides a second-class charging pile. In the second-class charging pile, the first storage capacity is less than the required capacity of the vehicle, but the mains can charge the second energy storage module 120 while the first energy storage module 110 is charging the vehicle. The design also takes into account that if the vehicle is connected to the second-class charging pile for charging at the same time, the area where the charging pile system is located is designated as the peak electricity consumption period. The second-class charging pile needs to be charged in order according to the peak queue number specified by the charging pile system. At this time, the estimated longest charging time can be calculated. The monitoring device 200 sends the parameter data of each standby first-class charging pile and the parameter data of each standby second-class charging pile to the vehicle that sends the vehicle charging request. The user can select as needed. The parameter data is clear and explicit. The design pushes reliable charging data to the user in the peak-shifting electricity consumption scenario, which is convenient for the user to select the charging pile and properly arrange the time.

[0058] In some embodiments of the application, as shown inFig. 5 As shown, in the calculation of the estimated longest charging time of the second-class charging pile according to the peak queue number, the number of second-class charging piles being charged, the first charging time of each second-class charging pile being charged, and the first charging time of the second-class charging pile, the following is included:

[0059] S510, sorting each second-class charging pile being charged according to the charging sequence;

[0060] S520, sequentially adding each second-class charging pile being charged to N peak charging queues, N being the peak queue number;

[0061] S530, calculating the charging cumulative duration of each peak charging queue, wherein the charging cumulative duration of each peak charging queue is the sum of the first charging time of each second-class charging pile in the peak charging queue;

[0062] S540, adding the shortest charging cumulative duration and the first charging time of the second-class charging pile to obtain the estimated longest charging time of the second-class charging pile.

[0063] It should be noted that when the power peak period is entered, only a limited number of charging piles in the charging pile system are allowed to be charged by the mains at the same time. Therefore, when calculating the estimated longest charging time of the target second-class charging pile, the second-class charging piles that have been charging or are confirmed to be charging are sorted according to the charging sequence, and then are sequentially added to each peak charging queue. At this time, it can be simulated that when the present time enters the peak power peak period, the target second-class charging pile will be arranged in which peak charging queue, and the estimated longest charging time is calculated accordingly.

[0064] Specifically, N can be set by the manufacturer, can be specified by the power supply department, or in the actual operation process, N can also be set and modified by the staff, for example, N can be 5, 8, 10, etc.

[0065] In some embodiments of the present application, the sequentially adding each second-class charging pile being charged to N peak charging queues includes:

[0066] When adding the second-class charging pile to the peak charging queue, the second-class charging pile is added to the peak charging queue with the shortest charging cumulative duration at the time.

[0067] It can be understood that in step S520, since each second-class charging pile being charged has been sorted, each second-class charging pile being charged can be sequentially selected and added in each peak charging queue. The second-class charging pile is added to the peak charging queue with the shortest charging cumulative duration at the time, simulating the arrangement of the subsequent actual charging process, and obtaining a relatively required estimated longest charging time.

[0068] In some embodiments of the present application, the vehicle charging request further comprises a vehicle charging speed;

[0069] In some embodiments of the present application, the method further comprises:

[0070] calculating an estimated shortest charging time of the standby charging pile device 100 according to the vehicle charging speed;

[0071] The parameter data of the first charging pile and the parameter data of the second charging pile further comprise the estimated shortest charging time.

[0072] In order to facilitate the user to arrange the time, before charging, the user can choose fast charging or slow charging and other charging methods, different charging methods correspond to different vehicle charging speeds, and according to the vehicle charging speed, the estimated shortest charging time of the user in selecting the first charging pile or the second charging pile can be calculated.

[0073] In some embodiments of the present application, the method further comprises:

[0074] The estimated shortest charging time of the first charging pile is the required vehicle power divided by the vehicle charging speed.

[0075] In the first charging pile, the first energy storage module 110 directly charges the vehicle, so that the quotient of the required vehicle power divided by the vehicle charging speed is obtained to obtain the estimated shortest charging time.

[0076] In some embodiments of the present application, the method further comprises:

[0077] calculating a second charging time of the second charging pile, the second charging time being the first storage power divided by the vehicle charging speed;

[0078] calculating a third charging time of the second charging pile, the third charging time being the supplementary charging power divided by the vehicle charging speed;

[0079] When the second charging time is greater than the first charging time, the estimated shortest charging time of the second charging pile is the sum of the second charging time and the third charging time;

[0080] When the first charging time is greater than the second charging time, the estimated shortest charging time of the second charging pile is the sum of the first charging time and the third charging time.

[0081] In the calculation of the estimated shortest charging time of the second charging pile, the second charging time of the first energy storage module 110 charging the vehicle is calculated first. If the second charging time is greater than the first charging time, it proves that the power supply has charged the second energy storage module 120 with the supplementary charging capacity before the first energy storage module 110 depletes the first storage capacity. Therefore, the estimated shortest charging time of the second charging pile is the sum of the second charging time and the third charging time. If the first charging time is greater than the second charging time, it proves that the power supply has not charged the second energy storage module 120 with the supplementary charging capacity when the first energy storage module 110 depletes the first storage capacity. Therefore, the vehicle needs to wait until the power supply charges the second energy storage module 120 with the supplementary charging capacity before the second energy storage module 120 can charge the vehicle. Therefore, the estimated shortest charging time of the second charging pile is the sum of the first charging time and the third charging time.

[0082] In some embodiments of the present application, the calculation of the first charging time according to the supplementary charging capacity, the second storage capacity, and the charging speed of the charging pile includes:

[0083] When the supplementary charging capacity is less than the second storage capacity, the first charging time is zero.

[0084] When the supplementary charging capacity is greater than the second storage capacity, the difference between the supplementary charging capacity and the second storage capacity is calculated to obtain a charging difference, and the charging difference is divided by the charging speed of the charging pile to obtain the first charging time.

[0085] It can be understood that for some charging piles, the second energy storage module 120 itself also stores some capacity. Therefore, when calculating the first charging time, when the supplementary charging capacity is less than the second storage capacity, the first charging time is zero. When the supplementary charging capacity is greater than the second storage capacity, the difference between the supplementary charging capacity and the second storage capacity is calculated to obtain the first charging time.
