[0025] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments.

It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein.

For example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products, or devices; "plurality" means two or more.

[0027] The method embodiments provided in the embodiments of the present application can be executed in a computer terminal or similar computing device or cloud platform or independent physical server or software platform, wherein the above software platform is run through one or more servers. Taking running on a computer terminal as an example, Figure 1FIG. 1 is a hardware structure block diagram of a computer terminal of a vehicle charging method according to an embodiment of the present application. Figure 1 As shown, the computer terminal may include one or more ( Figure 1 Only one is shown in the figure) processor 102 and memory 104 for storing data. In an exemplary embodiment, the computer terminal may also include a transmission device 106 for communication functions and an input and output device 108, wherein the processor 102 may include but is not limited to a processing device such as a microprocessor MCU or a programmable logic device FPGA. A person skilled in the art can understand that Figure 1 The structure shown is only for illustration and does not limit the structure of the above-mentioned computer terminal. Figure 1 More or fewer components as shown, or with Figure 1 Equivalent functions or comparisons shown Figure 1 A different configuration with more features is shown.

[0028] The memory 104 can be used to store computer programs, for example, software programs and modules of application software, such as computer programs corresponding to the methods in the embodiments of the present application. The processor 102 executes various functional applications and data processing by running the computer programs stored in the memory 104, that is, the above-mentioned methods are implemented. The memory 104 may include a high-speed random access memory, and may also include a non-volatile memory, such as one or more magnetic storage devices, flash memory, or other non-volatile solid-state memory. In some examples, the memory 104 may further include a memory remotely arranged relative to the processor 102, and these remote memories may be connected to the computer terminal via a network.

In one example, the transmission device 106 can be a radio frequency (RF) module, which is used to communicate with the Internet wirelessly.

[0030] In this embodiment, a vehicle charging method is provided, which is applied to the above-mentioned computer terminal. Figure 2 : is a flow chart of a vehicle charging method according to an embodiment of the present application, the process includes the following steps:

[0031] Step S202, obtaining the remaining power corresponding to each of the plurality of first vehicles in the target area;

[0032] The target area may be a charging area with charging piles, for example, a charging area in a community.

[0033] Step S204, grouping the plurality of first vehicles according to the remaining power to obtain a plurality of groups and a charging priority corresponding to each group;

[0034] It is understandable that the plurality of first vehicles may be grouped according to the remaining power, for example, the remaining power of vehicle 1 is 20%, the remaining power of vehicle 2 is 25%, and the remaining power of vehicle 3 is 80%. Vehicles 1 and 2 may be vehicles of set 1, and vehicle 3 may be a vehicle of set 2.

[0035] Step S206, determining charging sub-priorities corresponding to the multiple vehicles in each set according to the charging strategy corresponding to each charging priority;

[0036] The charging strategies corresponding to vehicles of each charging priority can be different. For example, the charging sub-priority of a vehicle corresponding to priority 1 can be determined based on the remaining power of the vehicle. The charging sub-priority of a vehicle corresponding to priority 2 can be determined based on the distance from the charging device.

[0037] Step S208: charging the plurality of first vehicles according to the charging priority and the charging sub-priority, so as to charge the plurality of first vehicles to a target power level.

[0038] The target power level may be 100% power level.

[0039] Through the embodiment of the present application, the remaining power corresponding to each of the multiple first vehicles in the target area is obtained, and the multiple first powers are grouped according to the remaining power to obtain multiple sets and the charging priority corresponding to each set; the charging sub-priority corresponding to the multiple vehicles in each set is determined according to the charging strategy corresponding to each charging priority, and the multiple first vehicles are charged according to the charging priority and the charging sub-priority to charge the multiple first vehicles to the target power. Through the technical solution of the embodiment of the present application, the multiple first vehicles in the target area are grouped according to the remaining power to determine multiple sets. First, the charging priority is assigned to the multiple sets, and secondly, for the vehicles in each set, the charging sub-priority of each vehicle is determined, and then the multiple first vehicles are charged according to the charging priority and the charging sub-priority. It can solve the problem of unreasonable allocation of charging equipment when charging multiple vehicles due to the limited charging equipment in the target area in the related art. Then the charging equipment can be reasonably allocated.

[0040] Optionally, the above-mentioned grouping of the multiple first vehicles according to the remaining power to obtain multiple sets and the charging priority corresponding to each set includes: determining multiple second vehicles whose remaining power is less than the first power among the multiple first vehicles, dividing the multiple second vehicles into a first set, and determining the charging priority of the first set to be the first charging priority, wherein the first charging priority is the highest priority; determining multiple third vehicles whose remaining power is greater than or equal to the first power and less than the second power among the multiple first vehicles, dividing the multiple third vehicles into a second set, and determining the charging priority of the second set to be the second charging priority; determining multiple fourth vehicles whose remaining power is greater than or equal to the second power and less than the third power among the multiple first vehicles, dividing the multiple fourth vehicles into a third set, and determining the charging priority of the third set to be the third charging priority, wherein the priority of the second charging priority is greater than the third charging priority; determining multiple fifth vehicles whose remaining power is greater than or equal to the third power and less than the target power among the multiple first vehicles, dividing the multiple fifth vehicles into a fourth set, and determining the charging priority of the fourth set to be the fourth charging priority, wherein the fourth charging priority is the lowest charging priority.

[0041] It is understandable that the implementation of this application can divide multiple first vehicles in the target area into four sets. The remaining power of the vehicles included in the four sets is different. In the first set, the remaining power of multiple second vehicles is less than the first power, the remaining power of multiple third vehicles in the second set is greater than or equal to the first power, and less than the second power, the remaining power of multiple fourth vehicles in the third set is greater than or equal to the second power, and less than the third power, and the remaining power of multiple fifth vehicles in the fourth set is greater than or equal to the third power, and less than the target power. For example: the first power can be 30%, the second power can be 50%, the third power can be 80%, and the target power can be 100%.

[0042] The charging priority of the first set may be the first charging priority, the charging priority of the second set may be the second charging priority, the charging priority of the third set may be the third charging priority, and the charging priority of the fourth set may be the fourth charging priority. The priority relationship between the first charging priority and the fourth charging priority may be: the first charging priority> the second charging priority> the third charging priority> the fourth charging priority.

[0043] Optionally, the above-mentioned determining charging sub-priorities corresponding to the multiple vehicles in each set respectively according to the charging strategy corresponding to each charging priority includes:

[0044] (1) When the charging priority is the first charging priority, determine a first time duration for charging each second vehicle in the first set to the second power; determine a first size relationship between multiple first time durations and a preset time duration; and determine a charging sub-priority for each second vehicle based on the first size relationship.

[0045] Wherein, determining the charging sub-priority of each second vehicle according to the first size relationship includes: when the first size relationship indicates that the multiple first time periods are all greater than the preset time period, determining a first difference between each first time period and the preset time period, and determining the charging sub-priority of each second vehicle according to the first difference; when the first size relationship indicates that the multiple first time periods are all less than or equal to the preset time period, determining the charging sub-priority of each second vehicle according to the remaining power of each second vehicle; when the first size relationship indicates that there is a second time period greater than the preset time period and a third time period less than or equal to the preset time period among the multiple first time periods, determining a second difference between the second time period and the preset time period, and determining the charging sub-priority of the second vehicle corresponding to the second time period according to the second difference, and determining the charging sub-priority of the second vehicle corresponding to the third time period according to the remaining power of the second vehicle corresponding to the third time period, wherein the charging sub-priority of the second vehicle corresponding to the third time period is less than the charging sub-priority of the second vehicle corresponding to the second time period.

[0046] It is understandable that, when the charging priority is the first charging priority, a first time duration for charging each second vehicle to the second power can be determined, and the charging sub-priority of each second vehicle can be determined according to a first size relationship between the first time duration and the preset time duration. For example:

[0047] 1) The preset duration is 5 minutes, the time for the second vehicle 1 to charge to the second power is 7 minutes, the time for the second vehicle 2 to charge to the second power is 6 minutes, and the time for the second vehicle 3 to charge to the second vehicle is 8 minutes, then the first difference corresponding to the second vehicle 1 is determined to be 2 minutes, the first difference corresponding to the second vehicle 2 is 1 minute, and the first difference corresponding to the second vehicle 3 is 3 minutes. It can be determined that the charging sub-priority of the second vehicle 2 is less than the charging sub-priority of the second vehicle 1, which is less than the charging sub-priority of the second vehicle 3.

[0048] 2) The preset duration is 5 minutes, the time for the second vehicle 4 to charge to the second power is 4 minutes, the time for the second vehicle 2 to charge to the second power is 3 minutes, and the time for the second vehicle 3 to charge to the second vehicle is 2 minutes. It can be determined that the charging duration of the second vehicles 4-6 is less than the preset duration, and the remaining power of the second vehicles 4-6 needs to be determined. Assume that the remaining power of the second vehicle 4 is 25%, the remaining power of the second vehicle 5 is 20%, and the remaining power of the second vehicle 6 is 15%. Then the charging sub-priority of the second vehicle 6 is greater than the charging sub-priority of the second vehicle 5, which is greater than the charging sub-priority of the second vehicle 4.

[0049] 3) The preset duration is 5 minutes, the time for the second vehicle 7 to charge to the second power is 3 minutes, the time for the second vehicle 8 to charge to the second power is 4 minutes, the time for the second vehicle 9 to charge to the second power is 6 minutes, and the time for the second vehicle 10 to charge to the second power is 7 minutes. It is determined that the remaining power of the second vehicle 7 is 25%, the remaining power of the second vehicle 8 is 20%, the second difference corresponding to the second vehicle 9 is 1 minute, and the second difference corresponding to the second vehicle 10 is 2 minutes. It can be determined that the charging sub-priority of the second vehicle 10 is greater than the charging sub-priority of the second vehicle 9, which is greater than the charging sub-priority of the second vehicle 8, which is greater than the charging sub-priority of the second vehicle 7.

[0050] (2) When the charging priority is the second charging priority, determine a fourth time duration for charging each third vehicle in the second set to the third power; and determine a second charging sub-priority for each fourth vehicle according to a second size relationship among multiple fourth time durations.

[0051] It can be understood that, when the charging priority is the second charging priority, the fourth time duration for charging each third vehicle to the third power can be determined, and the second charging sub-priority can be determined according to the second size relationship of each fourth time duration. For example: assuming that the third power is 55%, the time duration for charging the third vehicle 1 to 55% is 4 minutes, the time duration for charging the third vehicle 2 to 55% is 5 minutes, and the time duration for charging the third vehicle 3 to 55% is 6 minutes. It can be determined that 6 minutes>5 minutes>4 minutes, that is, the charging sub-priority of the third vehicle 3>the charging sub-priority of the third vehicle 2>the charging sub-priority of the third vehicle 1.

[0052] (3) when the charging priority is the third charging priority, determining a parking time for each fourth vehicle in the third set to park in the target area; and determining a charging sub-priority for each fourth vehicle according to the parking time.

[0053] It is understandable that, when the charging priority is the third charging priority, the parking time of each fourth vehicle in the target area can be determined, and the charging sub-priority of the fourth vehicle can be determined according to the parking time. For example, the parking time of the fourth vehicle 1 is 8:00 a.m. on May 25, 2024, the parking time of the fourth vehicle 2 is 9:00 a.m. on May 25, 2024, and the parking time of the fourth vehicle 3 is 10:00 a.m. on May 25, 2024. Then it can be determined that the charging sub-priority of the fourth vehicle 1> the charging sub-priority of the fourth vehicle 2> the charging sub-priority of the fourth vehicle 3.

[0054] (4) When the charging priority is the fourth charging priority, determine the shortest distance between each fifth vehicle in the fourth set and the charging device in the target area; and determine the charging sub-priority of each fifth vehicle based on the shortest distance.

[0055] It can be understood that, when the charging priority is the fourth priority, the shortest distance between each fifth vehicle and the charging device in the target area can be determined, and the charging sub-priority of each fifth vehicle can be determined according to the shortest distance.

[0056] For example, the shortest distance between the fifth vehicle 1 and the charging device is 2 meters, the shortest distance between the fifth vehicle 2 and the charging device is 3 meters, and the shortest distance between the fifth vehicle 3 and the charging device is 4 meters. Then the charging sub-priority of the fifth vehicle 1 is greater than the charging sub-priority of the fifth vehicle 2 and the charging sub-priority of the fifth vehicle 3.

[0057] The charging device may be: a smart charging device using a vehicle to everything (V2X) wireless communication technology mounted on an overhead crane. The V2X smart charging device mounted on an overhead crane may move toward the direction of the new energy vehicle to be charged (i.e., the multiple first vehicles of the present application).

[0058] Figure 3 is a schematic diagram of the target area structure according to an embodiment of the present application (top view), Figure 4 is a schematic diagram of the structure of the target area according to an embodiment of the present application (oblique view). Figure 3 , Figure 4 As shown, Figure 3 , Figure 4 The smart charging device is included. Specifically: ① is the target area (such as an underground garage, etc.); ② is the parking space (multiple) included in the target area, and the parking space can park multiple first vehicles; ③ overhead crane track-horizontal; ④ overhead crane track-vertical; ⑤ AC-DC power supply (i.e. AC power supply-DC power supply); ⑥ smart charging device (i.e. the charging device of this application). The smart charging device moves through ③ and ④.

[0059] The V2X-based intelligent mobile charging device has a robotic arm that can be extended and retracted in the vertical direction and rotated 360° in the vertical direction. The end of the robotic arm is equipped with a GB standard 800V fast charging gun. The charging gun is backward compatible with fast charging and slow charging modes with voltages below 800V. The charging gun can be inserted into the charging port of new energy vehicles with the same GB standard with full dimensional freedom.

[0060] In order to better understand the process of the charging method of the above-mentioned vehicle, the charging method of the above-mentioned vehicle is described below in combination with an optional embodiment, but it is not used to limit the technical solution of the embodiment of the present application.

[0061] In the related technology, if the parking spaces with charging piles are added as home parking spaces, as a common charging scene, the number of charging piles is limited by the power supply conditions of the community. Equipping each electric car with a home charging pile will lead to a great waste of charging pile resources. For example: With the development of technology, high-voltage fast charging (60KW charging power) has gradually become the mainstream. If 1,000 charging piles are equipped, the owner goes home from get off work at 7 o'clock in the evening, and 1,000 new energy vehicles are charged at the same time (charged with a charging power of 60,000KW). The power grid of the community will not be able to bear such a large power load, and at other times, most of the charging piles are idle. Therefore, many new energy vehicle owners cannot obtain approval to install charging piles.

[0062] The charging device and the charging method in the related art mainly connect several charging circuits to the transformer circuit, each charging circuit is installed in a main installation wire trough, and the cables of each charging circuit pass through the main installation wire trough and then enter the wire storage box through the secondary wire trough respectively; the wire storage box can store the cables, and the charging method can realize charging of one or more new energy vehicles. However, the above charging device and the charging method cannot solve the problem of unreasonable allocation of charging equipment when charging multiple vehicles due to the limited charging equipment in the target area in the related art.

[0063] An optional embodiment of the present application provides a V2X-based smart charging device and a charging method thereof. The charging equipment includes: roadside equipment (RSU), overhead crane track, smart charging device and charging gun. After the vehicle enters the parking space, the RSU receives the vehicle information of the vehicle (including the vehicle model, remaining power, location information, etc.), and records the parking time and saves it in the RSU. When the smart charging device requests vehicle data, the vehicle information within the charging range of the charging device is sent to the smart charging device, and the charging device then charges the vehicles within its charging range. The charging sequence can also be intelligently planned based on the car owner's car usage habits recorded by the RSU. On the one hand, it can prioritize the charging of vehicles that need to use the car in a short period of time, and on the other hand, it can maximize the utilization of the charging equipment. Specifically, Figure 5is a schematic diagram of a charging method for a V2X-based smart charging device according to an optional embodiment of the present application, such as Figure 5 As shown:

[0064] Step S501, obtaining vehicle information in a charging pairing sequence, the vehicle information including: remaining power and estimated vehicle use time, etc.

[0065] After the vehicle is parked in the parking space, the RSU obtains vehicle information (including vehicle model, remaining power, location information, etc.) through the vehicle's on-board unit (OBU), records the parking time, and predicts the next time the vehicle is used based on the vehicle's usage habits.

[0066] Step S502, according to the remaining power of the vehicles, the vehicles are divided into: vehicles with a remaining power of less than 30% (i.e., multiple second vehicles of the present application), vehicles with a remaining power of greater than or equal to 30% and less than 50% (i.e., multiple third vehicles of the present application), vehicles with a remaining power of greater than or equal to 50% and less than 80% (i.e., multiple fourth vehicles of the present application), and vehicles with a remaining power of greater than or equal to 80% and less than 100% (i.e., multiple fifth vehicles of the present application).

[0067] For a vehicle with a remaining power of less than 30%, steps S503 - 1 to S503 - 4 are executed.

[0068] For a vehicle with a remaining power greater than or equal to 30% and less than 50%, steps S504 - 1 to S504 - 2 are executed.

[0069] For a vehicle with a remaining power greater than or equal to 50% and less than 80%, step S505 is executed.

[0070] For a vehicle with a remaining power greater than or equal to 80% and less than 100%, step S506 is executed.

[0071] The smart charging device requests vehicle information, obtains vehicle information within the charging range of the smart charging device and the parking time of the vehicle from the RSU, updates the charging queue sequence, adds the newly parked vehicle to the charging queue sequence and removes the departing vehicle from the charging queue.

[0072] Step S503-1, for a vehicle with a remaining power of less than 30%, calculate the time t_55 required to charge to 55% (or the time required to charge to 50%).

[0073] Step S503-2, determining the relationship between t_55 and the preset time t, that is, determining whether t_55 is greater than t.

[0074] When it is determined that t_55>t, step S503-3 is executed, and when it is determined that t_55≤t, step S503-4 is executed.

[0075] Step S503-3, when it is determined that t_55>t, select the vehicles with t_55>t, and select the vehicle with the largest t_55>t to charge until the power is 55%.

[0076] Step S503-4: When it is determined that t_55≤t, the vehicle with the lowest power is selected for charging and charged to 55%.
