Description

Technical Field

[0001] The present invention relates to the field of new energy vehicle charging technology, and in particular to a peak-shifting charging control method and a charging pile system, a control device, and a storage medium. Background Art

[0002] New energy vehicles are gradually entering every household, and more and more clustered charging piles are forming charging pile systems in cities. Charging piles can convert municipal electricity into electricity to charge vehicles.

[0003] For larger cities, especially in summer, the city's electricity load is very large. Therefore, in the power supply bureau's power supply planning for the city, during peak hours, it will require each area to take turns to use electricity in staggered periods. Areas required to use low-voltage electricity need to cooperate in reducing electricity consumption. This requirement may be planned or sudden. Therefore, most existing charging piles are equipped with energy storage modules such as batteries or supercapacitors. During low-peak electricity consumption and standby periods when there is no vehicle charging, the energy storage modules can be used to store electricity first. During peak electricity consumption, the energy storage modules can also be used to charge vehicles.

[0004] However, in the existing charging pile safety regulations, it is usually prohibited to charge the energy storage module for the vehicle while the mains is charging the energy storage module at the same time. Moreover, when the power consumption is at peak, the charging pile system can only allow a limited number of charging piles (the number of peak queues) to charge at the same time. For a vehicle that needs to charge 200 degrees, when entering the charging pile system and selecting a charging pile, although the power consumption may be low at present, it is not certain when the peak power consumption will be implemented. The charging pile that does not store 200 degrees of electricity in the energy storage module does not meet the conditions for charging the vehicle. The user chooses to charge the charging pile that does not meet the charging conditions. When the vehicle is not fully charged and the power consumption coincides with peak, the charging pile's way of obtaining electricity from the mains is restricted. The user has no way of knowing when the vehicle can obtain the required amount of electricity, resulting in unreliable charging. The user may even need to go to the site to replace the charging pile. Summary of the Invention

[0005] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a peak-shifting charging control method, a charging pile system, a control device, and a storage medium. These methods deliver reliable charging data to users during peak-shifting electricity consumption scenarios, facilitating their selection of charging piles and proper scheduling.

[0007] Obtaining a vehicle charging request, wherein the vehicle charging request includes a required amount of power for the vehicle;

[0008] Checking each standby charging pile device according to the vehicle charging request to determine whether the charging pile meets the charging conditions of the vehicle, wherein the standby charging pile device is a charging pile device that is not charging the vehicle, wherein the checking of the charging pile device according to the vehicle charging request includes: obtaining a first stored power of the first energy storage module and a second stored power of the second energy storage module; when the first stored power is greater than the power required by the vehicle, marking the charging pile device as a first-class charging pile that meets the charging conditions of the vehicle;

[0009] When the first stored power is less than the power required by the vehicle, the difference between the power required by the vehicle and the first stored power is calculated to obtain the supplementary charge capacity; the first charging time is calculated based on the supplementary charge capacity, the second stored power, and the charging speed of the charging pile; when the first charging time is less than or equal to the off-peak grace time threshold, the charging pile device is marked as a second-class charging pile that meets the charging conditions of the vehicle;

[0010] Calculating an estimated maximum charging time for a second-class charging pile, wherein the number of second-class charging piles currently charging and the corresponding first charging times are counted, and the estimated maximum charging time for the second-class charging pile is calculated based on the number of peak queues, the number of second-class charging piles currently charging, the first charging time of each second-class charging pile currently charging, and the first charging time of the second-class charging pile. The number of peak queues is the number of second energy storage modules in the charging pile device that can be simultaneously charged with mains power in the charging pile system during peak power consumption periods.

[0012] A peak-shifting charging control method according to an embodiment of the present invention has at least the following beneficial effects:

[0013] In the staggered charging control method of the present invention, the charging pile device has at least a first energy storage module and a second energy storage module. While the first energy storage module is charging the vehicle, the second energy storage module can be charged by the mains, which saves time and ensures the safety of charging. When the user drives the vehicle into the place where the charging pile system is located and selects a charging pile for charging, a vehicle charging request will be sent to the monitoring device first. After receiving the vehicle charging request, the monitoring device can traverse and detect whether each standby charging pile device meets the charging conditions of the vehicle. If the first stored electricity in some charging pile devices is greater than the electricity required by the vehicle, it is equivalent to that even if the mains does not charge the second energy storage module, the charging pile device can already meet the electricity required by the vehicle. In this case, the charging pile device can be directly marked as a first-class charging pile. However, given that the number of first-class charging piles may be small and they may be far away from the location of the user's vehicle, For longer distances, this design also provides second-class charging piles. In the second-class charging piles, the first stored power is less than the power required by the vehicle, but while the first energy storage module is charging the vehicle, the AC power can charge the second energy storage module. This design also takes into account that if the area where the charging pile system is located is designated as a peak power consumption period while the vehicle is connected to the second-class charging pile for charging, the second-class charging pile needs to be charged in sequence according to the number of peak queues specified by the charging pile system. At this time, the estimated longest charging time can be calculated, and the monitoring device then 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 issued the vehicle charging request. The user can select as needed, and the parameter data is clear and unambiguous.

[0018] According to some embodiments of the present invention, the estimated minimum charging time of the standby charging pile device calculated according to the vehicle charging speed includes: calculating the second charging time of the second-class charging pile, the second charging time is the first stored power divided by the vehicle charging speed; calculating the third charging time of the second-class charging pile, the third charging time is the supplementary charging amount divided by the vehicle charging speed; when the second charging time is greater than the first charging time, the estimated minimum charging time of the second-class charging pile is the sum of the second charging time and the third charging time; when the first charging time is greater than the second charging time, the estimated shortest charging time of the second-class charging pile is the sum of the first charging time and the third charging time.

[0019] According to some embodiments of the present invention, the calculation of the first charging time based on the supplementary charging amount, the second stored amount and the charging speed of the charging pile includes: when the supplementary charging amount is less than the second stored amount, the first charging time is zero; when the supplementary charging amount is greater than the second stored amount, the difference between the supplementary charging amount and the second stored amount is calculated to obtain the difference to be charged, and the difference to be charged is divided by the charging speed of the charging pile to obtain the first charging time.

[0020] According to an embodiment of the second aspect of the present invention, a charging pile system includes multiple charging pile devices and a monitoring device, which is respectively communicatively connected to each charging pile device.

[0038] like Figures 1 to 2 As shown, a peak-shifting charging control method according to an embodiment of the first aspect of the present invention is applied to a charging pile system, the charging pile system includes a plurality of charging pile devices 100 and a monitoring device 200, the monitoring device 200 is respectively communicated with each charging pile device 100, the charging pile device 100 includes at least a first energy storage module 110, a second energy storage module 120, a charging switching module 130 and a discharging switching module 140, the input end of the charging switching module 130 is used to be connected to the mains, the output end of the charging switching module 130 is respectively connected to the first energy storage module 110 and the second energy storage module 120, the input end of the discharging switching module 140 is respectively connected to the first energy storage module 110 and the second energy storage module 120 The output end of the discharge switching module 140 is connected to the plug connector 160.

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

[0040] The charging switching module 130 and the discharging switching module 140 can both be electrically controlled multi-speed switches. A control module 150 is also provided in the charging pile device 100. The control module 150 is respectively connected to the charging switching module 130 and the discharging switching module 140. The control module 150 is provided with a CPU and its auxiliary circuits. The control module 150 is also provided with relevant circuits for detecting the power of the first energy storage module 110 and the second energy storage module 120. The control module 150 can control the charging switching module 130 and the discharging switching module 140 to switch the connection state, wherein the charging switching module 130 can make the mains power and the second energy storage module 120 conductive and the mains power and the first energy storage module 110 disconnected, and can also make the mains power and the second energy storage module 120 disconnected and the mains power and the first energy storage module 110 conductive, and can also make the mains power and the second energy storage module 120 and the first energy storage module 110 disconnected.

[0041] like Figures 3 to 4 As shown, the peak-shifting charging control method includes:

[0042] S310: Obtain a vehicle charging request, wherein the vehicle charging request includes a required amount of power for the vehicle;

[0043] S320: Check each standby charging pile device 100 according to the vehicle charging request to determine whether the charging pile meets the charging conditions of the vehicle. The standby charging pile device 100 is a charging pile device 100 that is not charging the vehicle. The checking of the charging pile device 100 according to the vehicle charging request includes:

[0044] S410, obtaining a first stored amount of electricity of the first energy storage module 110 and a second stored amount of electricity of the second energy storage module 120;

[0045] S420: When the first stored power is greater than the power required by the vehicle, marking the charging pile device 100 as a first-class charging pile that meets the charging conditions of the vehicle;

[0046] S430: When the first stored power is less than the power required by the vehicle, calculating the difference between the power required by the vehicle and the first stored power to obtain a supplementary charge capacity;

[0047] S440, calculating a first charging time according to the supplementary charge amount, the second stored amount of electricity, and the charging speed of the charging pile;

[0048] S450: When the first charging time is less than or equal to the off-peak grace time threshold, the charging pile device 100 is marked as a second-class charging pile that meets the charging conditions of the vehicle;

[0049] S460, calculating an estimated maximum charging time for a second-class charging pile, wherein the number of second-class charging piles being charged and the corresponding first charging times are counted, and the estimated maximum charging time for the second-class charging pile is calculated based on the number of peak queues, 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 number of peak queues is the number of second energy storage modules 120 in the charging pile device 100 that are allowed to be charged simultaneously with mains power in the charging pile system during peak power consumption periods;

[0050] S330. Send the parameter data of each first-class charging pile on standby and the parameter data of each second-class charging pile on standby to the vehicle that issues the vehicle charging request, wherein the parameter data of the first-class charging pile includes the location information of the first-class charging pile, and the parameter data of the second-class charging pile includes the location information of the second-class charging pile and the corresponding estimated maximum charging time.

[0051] When a vehicle enters a parking lot, it can send a vehicle charging request to the cloud server 210. The amount of electricity required by the vehicle can be calculated from the total amount of electricity stored in the vehicle and the remaining electricity of the vehicle, or it can be set by the user.

[0052] The charging pile device 100 is provided with a first energy storage module 110 and a second energy storage module 120. During the execution of the peak-shifting charging control method, the energy storage module with higher storage capacity is used as the first energy storage module 110, and the energy storage module with lower storage capacity is used as the second energy storage module 120.

[0053] In addition, in step S330, the user can obtain parameter data from the vehicle, and the user can know the location of the first-class charging piles and the second-class charging piles. The number of first-class charging piles is small, and they can be farther away from the vehicle at this time, while the number of second-class charging piles is large. The user can choose as needed, and can send a binding instruction to the selected charging pile through the vehicle, and match the charging after the vehicle moves to the corresponding charging pile.

[0054] It can be understood that the peak grace time threshold is the maximum time that the mains power in the second-class charging pile is allowed to serve the second energy storage module 120 when entering the peak power consumption period. This peak grace time threshold can be set by the manufacturer or stipulated by the power supply department, so as to ensure the reasonable planning of urban peak power consumption and reduce the urban power load. The charging speed of the charging pile is set according to the actual speed at which the mains power charges the charging pile.

[0055] When calculating the estimated maximum charging time of a second-class charging pile, since in most cases it is impossible to accurately know when the peak electricity consumption period will begin, it is assumed that the peak electricity consumption period has already begun. Even if the second energy storage module 120 of some second-class charging piles has been charged for a certain period of time, the first charging time is still used for calculation in step S460. In addition, since the estimation assumes that the peak electricity consumption period has already begun, each second-class charging pile is immediately entered into the peak charging queue for calculation, thereby obtaining an estimated maximum charging time and providing it to the user. In the subsequent actual charging process, it is possible that the electricity consumption period has always been off-peak, and the estimated maximum charging time can be greatly shortened, and the actual charging time will be less than the estimated maximum charging time. Since the user has been provided with a reference for the estimated maximum charging time, the substantial reduction in the actual charging time can also meet the user's requirements.

[0056] In the peak-shifting charging control method of the present invention, the charging pile device 100 includes at least a first energy storage module 110 and a second energy storage module 120. While the first energy storage module 110 is charging the vehicle, the second energy storage module 120 can be charged by the mains, saving time and ensuring charging safety.

[0057] When the user drives the vehicle into the place where the charging pile system is located and selects a charging pile for charging, a 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 stored power in some charging pile devices 100 is already greater than the power required by the vehicle, it is equivalent to that even if the mains power does not charge the second energy storage module 120, the charging pile device 100 can already meet the power required by the vehicle. In this case, the charging pile device 100 can be directly marked as a first-class charging pile. However, in view of the fact that the number of first-class charging piles may be small and they may be far away from the location of the user's vehicle, this design also provides a second-class charging pile. In the second-class charging pile, the first stored power is less than The amount of electricity required by the vehicle, but while the first energy storage module 110 is charging the vehicle, the AC power can charge the second energy storage module 120. The present design also takes into account that if the area where the charging pile system is located is designated as a peak power consumption period while the vehicle is connected to the second-class charging pile for charging, the second-class charging pile needs to be charged in sequence according to the number of peak queues specified by the charging pile system. At this time, the estimated maximum charging time can be calculated, and the monitoring device 200 then 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 issued the vehicle charging request. The user can select as needed, and the parameter data is clear and unambiguous. The present design pushes reliable charging data to users in the scenario of off-peak power consumption, making it convenient for users to select charging piles as needed and properly arrange time.

[0058] In some embodiments of the present invention, Figure 5 As shown, the estimated maximum charging time of the second-class charging pile calculated based on the number of peak queues, 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 includes:

[0059] S510, sorting the second-class charging piles that are charging in order of charging;

[0060] S520: Add each second-class charging pile that is currently charging to N peak charging queues in sequence, where N is the number of peak queues.

[0061] S530: Calculate the cumulative charging time of each peak charging queue, where the cumulative charging time 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: Add the shortest cumulative charging time and the first charging time of the second-class charging pile to obtain an estimated maximum charging time of the second-class charging pile.

[0063] It should be noted that when entering the peak electricity consumption period, 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 maximum charging time of the target second-class charging pile, the second-class charging piles that have been charging or confirmed to be charging are first sorted in order of charging, and then added one by one to each peak charging queue. At this time, it can be simulated that when entering the peak electricity consumption period, the target second-class charging pile will be arranged into which peak charging queue, and the estimated maximum charging time can be calculated accordingly.

[0064] Specifically, N can be set by the manufacturer or 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 invention, sequentially adding each of the second-class charging piles being charged to the N peak charging queues includes:

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

[0067] It can be understood that in step S520, since the second-class charging piles that are being charged have been sorted, each second-class charging pile that is being charged can be selected and added to each peak charging queue one by one, and the second-class charging piles are added to the peak charging queue with the shortest cumulative charging time at this time, so as to simulate the arrangement of the subsequent actual charging process and obtain an estimated maximum charging time that is relatively in line with the requirements.

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

[0069] After checking each standby charging pile device 100 according to the vehicle charging request and determining whether the charging pile meets the charging conditions of the vehicle, the method further includes:

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

[0071] The parameter data of first-class charging piles and second-class charging piles also include the estimated minimum charging time.

[0072] To make it easier for users to arrange their time, before charging, users can choose fast charging or slow charging. Different charging methods correspond to different vehicle charging speeds. Based on the vehicle charging speed, the estimated shortest charging time for users choosing a first-class charging pile or a second-class charging pile can be calculated.

[0073] In some embodiments of the present invention, the calculation of the estimated shortest charging time of the standby charging pile device 100 according to the vehicle charging speed includes:

[0074] The estimated minimum charging time for a first-class charging station is the amount of electricity required by the vehicle divided by the vehicle's charging speed.

[0075] In a first-class charging station, the vehicle is directly charged by the first energy storage module 110 . Therefore, the estimated shortest charging time is obtained by dividing the power required by the vehicle by the vehicle charging speed.

[0076] In some embodiments of the present invention, the calculation of the estimated shortest charging time of the standby charging pile device 100 according to the vehicle charging speed includes:

[0077] Calculate the second charging time of the second-class charging pile, where the second charging time is the first stored power divided by the vehicle charging speed;

[0078] Calculate the third charging time of the second-class charging pile, which is the supplementary charging amount divided by the vehicle charging speed;

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

[0081] In the calculation of the estimated minimum charging time for the second-class charging pile, the second charging time for the first energy storage module 110 to charge the vehicle is first calculated. If the second charging time is greater than the first charging time, it proves that before the first energy storage module 110 exhausts the first stored electricity, the mains has already charged the second energy storage module 120 with a supplementary charging amount. Therefore, the estimated minimum charging time of the second-class 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 when the first energy storage module 110 exhausts the first stored electricity, the mains has not yet charged the second energy storage module 120 with a supplementary charging amount. It is necessary to wait for the mains to fully charge the second energy storage module 120 with the supplementary charging amount before the second energy storage module 120 can charge the vehicle. Therefore, the estimated shortest charging time for the second-class charging pile is the sum of the first charging time and the third charging time.

[0082] In some embodiments of the present invention, calculating the first charging time according to the supplementary charge amount, the second stored charge amount, and the charging speed of the charging pile includes:

[0083] When the supplementary charge amount is less than the second stored charge amount, the first charging time is zero;

[0084] When the supplementary charge amount is greater than the second stored charge amount, the difference between the supplementary charge amount and the second stored charge amount is calculated to obtain a waiting-to-charge difference, and the waiting-to-charge difference is divided by the charging speed of the charging pile to obtain the first charging time.

[0085] It is understandable that for some charging piles, the second energy storage module 120 itself will also store some electricity. Therefore, when calculating the first charging time, when the supplementary charging amount is less than the second stored electricity, the first charging time is zero. When the supplementary charging amount is greater than the second stored electricity, it is necessary to calculate the difference between the supplementary charging amount and the second stored electricity to obtain the first charging time.
