Description

Technical Field

[0001] The present application relates to the technical field of charging piles, and in particular to a method for distributing electric energy within a mobile charging pile station. Background Art

[0002] As the core carrier of low-carbon transformation in the transportation sector, the technical architecture of new energy vehicles has broken through the paradigm of traditional fuel vehicles and built a multi-level collaborative innovation system. While saving energy and reducing emissions, it has also driven the rapid iteration and update of related technologies such as on-board batteries, fast charging, and on-board drive motors.

[0003] In particular, the technology for replenishing energy for new energy vehicles has opened up a variety of charging modes, including battery swapping, solar charging, and mobile charging. The advent of mobile charging piles has overcome the limitations of charging piles on the convenience of charging new energy vehicles, making charging deployment more flexible, significantly improving the utilization efficiency of charging piles, and further promoting the popularization and application of new energy vehicles.

[0004] An existing mobile charging pile is installed in the track of the charging station. The track is arranged along the new energy parking spaces. The mobile charging pile moves along the track to the location of the vehicle to perform charging. This type of mobile charging pile has a built-in battery that can drive itself to move and temporarily provide power to the vehicle.

[0005] When users of new energy vehicles are traveling to this charging station or charging, the following situations may occur: for example, the user needs to use the vehicle for a long distance in a short period of time, but the vehicle's own power is not enough for long-distance travel. If the power grid is unable to provide sufficient power supply to the charging station at this time, then this charging station will be unable to meet the power needs of such users, reducing the user experience of new energy vehicle users. Summary of the Invention

[0006] In order to meet the demand of new energy vehicles for fast charging through mobile charging piles in a short time, the present application provides an in-station power distribution method for mobile charging piles.

[0007] This application provides a method for distributing electric energy within a mobile charging station, which adopts the following technical solutions:

[0008] A method for distributing electric energy within a mobile charging station, comprising:

[0009] Obtain the user's charging demand type and the user's preset charging threshold;

[0010] If the charging demand type is strong, the grid system will stop supplying power to vehicles with weak power demand in the charging station, and control the power supply in the charging pile corresponding to the vehicle with weak power demand in the charging station to supply power to the vehicle with weak power demand;

[0011] After the power level of the vehicle with high power demand reaches the charging threshold, the power grid system is restored to supply power to the vehicle with low power demand in the charging station.

[0012] Through the above technical solution, after the user parks the new energy vehicle in the charging station and scans the code through the mobile terminal or other methods to call the charging pile for charging, the user's charging needs and other information have been obtained by the control system or operating system of the charging station.

[0013] User charging demand information includes charging demand type and charging threshold. Charging demand types include strong and weak demand. Strong demand refers to users' need to use the car for long distances in a short period of time, while weak demand refers to users' need for no long-distance travel in a short period of time. The charging threshold refers to the user's charging target, that is, the percentage of battery life the user wants to reach in a short period of time.

[0014] After the control system or operating system of the charging station obtains information such as the user's charging demand type and the user's preset charging threshold, if the charging demand type is a strong power demand and the power grid is unable to provide sufficient power supply to the charging station, the power grid system will stop supplying power to vehicles with weak power demand in the charging station, and control the power supply in the charging pile corresponding to the vehicle with weak power demand in the charging station to supply power to the vehicle with weak power demand. In this way, the power provided by the power grid can be concentrated to supply vehicles with strong power demand, thereby improving the charging power of new energy vehicles, shortening the charging time for vehicles with strong power demand to reach the charging threshold, and then meeting the needs of new energy vehicles to quickly charge through mobile charging piles in a short time, thereby improving user experience.

[0015] After the power of the vehicle with strong power demand reaches the charging threshold, the power grid system will resume supplying power to the vehicle with weak power demand in the charging station. On the one hand, it will speed up the charging speed of the vehicle with weak power demand, and on the other hand, it can replenish the power supply of the charging pile.

[0016] If the charging demand type of the user's vehicle is weak power demand, it can use the power grid system for charging without notifying the power grid system to supply electricity to other vehicles with weak power demand.

[0017] In a preferred example, the present application may be further configured such that after the power of the vehicle with high power demand reaches the charging threshold, the following steps are included:

[0018] Convert the charging demand type of the vehicle that has reached the charging threshold into a weak power demand;

[0019] Record the number of vehicles with strong power demand and the number of vehicles with weak power demand in the charging station before and after the charging demand type conversion;

[0020] Based on the number of vehicles with strong electricity demand and the number of vehicles with weak electricity demand before the charging demand type conversion, the ratio before the conversion is calculated; based on the number of vehicles with strong electricity demand and the number of vehicles with weak electricity demand after the charging demand type conversion, the ratio after the conversion is calculated;

[0021] Calculating a ratio change value based on the ratio value after the change and the ratio value before the change;

[0022] Comparison is made based on the ratio change value and a preset ratio comparison value;

[0023] If the proportional change value is greater than or equal to a preset proportional comparison value, the power grid system is restored to supply power to the vehicles with weak power demand in the charging station one by one.

[0024] Through the above technical solution, the charging demand type of vehicles that have reached the charging threshold is converted to weak power demand, and the power grid system needs to be restored to supply power to vehicles with weak power demand in the charging station. If a large number of charging units (that is, vehicles with weak power demand) are put into the power grid system in a short period of time, this will cause residents around the charging station to have a strong sense of it, which will not only cause varying degrees of damage to electrical equipment, but also affect the normal life and production of surrounding residents.

[0025] Therefore, we first record the number of vehicles with high and low power demands at the charging station before and after the charging demand type change. Based on this data, we calculate the ratio before and after the change. The ratio before the change is the ratio of the number of vehicles with low power demands to the number of vehicles with high power demands before the charging demand type change; the ratio after the change is the ratio of the number of vehicles with low power demands to the number of vehicles with high power demands after the charging type change.

[0026] By calculating the proportional change value based on the ratio before and after the change, we can know the change in the proportion of vehicles with weak power demand relative to vehicles with strong power demand before and after the change of charging demand type. The larger the proportional change value, the greater the proportion of vehicles with weak power demand that need to restore power supply to the grid. If the power grid is restored to charge such a high proportion of vehicles with weak power demand at the same time, it will increase the possibility of surrounding users feeling it, which will affect the normal life and production of surrounding residents.

[0027] The calculated proportional change value is compared with the preset proportional comparison value. If the proportional change value is greater than or equal to the proportional comparison value, the power grid system will be restored to supply power to vehicles with weak power demand in the charging station one by one to reduce user perception and reduce the impact of sudden changes in power supply of the power grid system on the normal life and production of surrounding residents.

[0028] The specific calculation steps of relevant values ​​are shown below.

[0029] In a preferred example, the present application may be further configured such that the calculation of the proportional change value adopts the following formula:

[0030] ,

[0031] is the proportional change value, is the number of vehicles with weak electricity demand before the charging demand type conversion, is the number of vehicles with strong electricity demand before the charging demand type conversion, is the ratio before the change, is the ratio after transformation.

[0032] With this technical solution, the ratio before the "-" in the formula is the ratio after the change, and the ratio after the "-" is the ratio before the change. The difference between the two is the ratio change. The reason the numerator of the ratio after the change is increased by one is because a vehicle with weak charging demand has been added. Similarly, the reason the denominator of the ratio after the change is decreased by one is because a vehicle with strong charging demand has been removed.

[0033] In a preferred example, the present application can be further configured such that if the proportional change value is less than the proportional comparison value, the power grid system is restored to supply power to vehicles with weak power demand in the charging station in batches or simultaneously.

[0034] Through the above technical solution, since the proportional change value is smaller than the proportional comparison value, even if the power grid system is restored to charge vehicles with weak power demand at the same time, it is difficult for surrounding residents to perceive it. Therefore, the power grid system can be restored to supply power to vehicles with weak power demand in the charging station in batches or at the same time, thereby reducing the operational steps for restoring the power grid system to supply power to vehicles with weak power demand and improving operational efficiency.

[0035] In a preferred example, the present application may be further configured such that the batch-by-batch restoration of power supply from the power grid system to vehicles with weak power demand in the charging station includes:

[0036] Calculating a ratio deviation value based on the ratio change value and the ratio comparison value;

[0037] Divide the deviation intervals into multiple deviation intervals according to the preset interval length;

[0038] Establishing a mapping relationship between multiple preset charging recovery quantities and multiple deviation intervals;

[0039] Based on the calculated proportional deviation value, matching the corresponding deviation interval;

[0040] Based on the deviation interval, obtaining a corresponding charging recovery quantity;

[0041] The power grid system is restored in sequence according to the preset interval time, and power is supplied to a number of vehicles with weak power demand corresponding to the charging restoration number.

[0042] Through the above technical solution, if the proportional change value is less than the proportional comparison value, the power grid system can be restored in batches to supply power to vehicles with weak power demand in the charging station. That is, multiple vehicles with weak power demand that originally relied on charging piles for charging can be divided into multiple batches to restore the power supply of the power grid system.

[0043] First, calculate the proportional deviation value, which is the difference between the proportional comparison value and the proportional change value. Based on the size of the proportional deviation value, determine the number of vehicles with weak power demand to restore power to the grid system in each batch. That is, set the corresponding charging recovery number for each deviation interval of the proportional deviation value.

[0044] After calculating the actual proportional deviation value, first match the deviation interval where the proportional deviation value is located, and obtain the corresponding charging recovery number based on the deviation interval, so as to determine the number of vehicles with weak power demand restored to the power grid system in each batch. If the number of vehicles with weak power demand that need to be restored at the end is less than the charging recovery number, the power grid system will directly restore the power supply to these vehicles with weak power demand.

[0045] In a preferred example, the present application may be further configured such that the calculation of the proportional deviation value adopts the following formula:

[0046] ,

[0047] is the proportional deviation value, is the ratio comparison value, is the proportional change value.

[0048] Through the above technical solution, the proportion deviation value can be obtained by subtracting the proportion change value from the proportion comparison value.

[0049] In a preferred example, the present application can be further configured such that before a vehicle with high power demand in a charging state reaches a charging threshold, if a user changes the charging demand type of the vehicle with high power demand in a charging state to a vehicle with low power demand or stops charging, the power grid system will be restored to supply power to the vehicle with low power demand in the charging station.

[0050] Through the above technical solution, before a vehicle with strong power demand in the charging state reaches the charging threshold, if the user changes the charging demand type of the vehicle with strong power demand in the charging state to weak power demand or stops charging through the mobile terminal, it means that the user's charging demand has weakened or there is no charging demand, and there is no need to provide a charging mode with strong charging demand for the user's car. At this time, the power grid system is directly restored to supply power to vehicles with weak power demand in the charging station, thereby speeding up the charging speed of other vehicles.

[0051] In a preferred example, the present application can be further configured such that before a vehicle with a strong power demand in a charging state reaches a charging threshold, if the charging station cannot receive power supply from the power grid system, the power supply in the charging pile corresponding to the vehicle is controlled to charge the vehicle.

[0052] Through the above technical solution, before a vehicle with strong power demand in the charging state reaches the charging threshold, a power outage, equipment maintenance, etc. occurs, resulting in the charging station being unable to receive power supply from the power grid system. At this time, the power supply in the charging pile corresponding to the vehicle is controlled to charge the vehicle so as to replenish power to the vehicle in time.

[0053] In a preferred example, the present application can be further configured such that if the electric energy released by the power source in the charging pile corresponding to the vehicle does not cause the vehicle to fail to reach the charging threshold, other charging piles are matched for the vehicle to perform charging for the vehicle.

[0054] Through the above technical solution, if the electric energy released by the charging pile currently used by the vehicle does not cause the vehicle to reach the charging threshold, other charging piles will be matched for the vehicle to charge the vehicle. The matched charging pile will travel to the location of the vehicle and continue to charge the vehicle, thereby extending the vehicle's cruising range and improving user experience.

[0055] In summary, this application has the following beneficial technical effects:

[0056] 1. If the user's vehicle has a strong charging demand and the power grid cannot provide sufficient power to the charging station, the power supply mode for vehicles with weak power demand in the charging station will be adjusted. In other words, the charging pile will be used to supply power to vehicles with weak power demand, and the power of the power grid will be concentrated to supply vehicles with strong power demand. This will increase the charging power of new energy vehicles and shorten the charging time for vehicles with strong power demand to reach the charging threshold. This will meet the needs of new energy vehicles for fast charging through mobile charging piles in a short time and improve the user experience.

[0057] 2. After the high-demand vehicle reaches the charging threshold, the grid system will restore power to the low-demand vehicles in the charging station. Based on the ratio change value and the ratio comparison value, it will be decided whether to restore power to the low-demand vehicles one by one or in batches. This will reduce the perceived power consumption of residents near the charging station, thereby minimizing the impact of sudden changes in the grid system's power supply on the normal life and production of nearby residents.

[0058] 3. If a power outage occurs at the charging station, the vehicle will be powered by the built-in power supply of the corresponding charging pile to replenish the vehicle with energy in time; if the corresponding charging pile of the vehicle is not sufficient to charge the vehicle to the charging threshold, the vehicle will be matched with other charging piles for power replenishment to extend the vehicle's range.

[0062] The following is combined with Figure 1 -Attached Figure 3 This application is described in further detail.

[0063] In an embodiment of the present application, a method for distributing power within a mobile charging pile is disclosed. The executor of this method may be an operating system or control system of a charging station using a mobile charging pile. The operating system or control system may control the power supply mode of the mobile charging pile, the movement, track change, and self-power supply of the mobile charging pile, and so on.

[0064] Refer to the attached Figure 1 As shown, a method for distributing electric energy within a mobile charging station includes the following processing steps:

[0065] S101: Obtain a user's charging requirement type and a user-preset charging threshold.

[0066] In practice, user charging demand information includes charging demand type and charging threshold. Charging demand types include strong and weak demand. Strong demand refers to users requiring long-distance driving within a short period of time, while weak demand refers to users requiring no long-distance driving within a short period of time.

[0067] The charging threshold refers to the user's charging goal, that is, the percentage of power that the user wants to charge in a short period of time.

[0068] S102: If the charging demand type is a strong power demand, stop the power grid system from supplying power to the vehicle with a weak power demand in the charging station, and control the power supply in the charging pile corresponding to the vehicle with a weak power demand in the charging station to supply power to the vehicle with a weak power demand.

[0069] During implementation, if the charging demand type is a strong power demand and the power grid is unable to provide sufficient power supply to the charging station, the power grid system will stop supplying power to vehicles with weak power demand in the charging station, and control the power supply in the charging pile corresponding to the vehicle with weak power demand in the charging station to supply power to the vehicle with weak power demand.

[0070] This will concentrate the electricity provided by the power grid to supply vehicles with strong electricity demand, improve the charging power of new energy vehicles, shorten the charging time for vehicles with strong electricity demand to reach the charging threshold, and thus meet the needs of new energy vehicles for fast charging through mobile charging piles in a short time.

[0071] If the charging demand type of the user's vehicle is weak power demand, it can use the power grid system for charging without notifying the power grid system to supply electricity to other vehicles with weak power demand.

[0072] S103: After the power of the vehicle with high power demand reaches the charging threshold, the power grid system is restored to supply power to the vehicle with low power demand in the charging station.

[0073] During implementation, after the power of vehicles with strong power demand reaches the charging threshold, the power grid system will be restored to supply power to vehicles with weak power demand in the charging station. This will not only speed up the charging speed of vehicles with weak power demand, but also replenish the power supply of the charging pile.

[0074] Refer to the attached Figure 2 As shown, after the power of a vehicle with high power demand reaches the charging threshold, the following processing steps are included:

[0075] S201: Convert the charging demand type of a vehicle that has reached a charging threshold into a weak power demand.

[0076] During implementation, after the battery level of a vehicle with strong power demand reaches the charging threshold, the vehicle's battery level has reached the owner's charging expectations and can meet the user's vehicle needs. At this time, the system will convert the charging demand type of the vehicle that has reached the charging threshold into a weak power demand.

[0077] S202: Record the number of vehicles with strong power demand and the number of vehicles with weak power demand in the charging station before and after the charging demand type conversion.

[0078] In implementation, that is, before the conversion of charging demand type, the number of vehicles with strong power demand and the number of vehicles with weak power demand in the charging station are obtained; and after the conversion of charging demand type, the number of vehicles with strong power demand and the number of vehicles with weak power demand in the charging station are obtained to provide data support for subsequent related calculations.

[0079] S203. Calculate the ratio before the conversion based on the number of vehicles with strong electricity demand and the number of vehicles with weak electricity demand before the conversion of the charging demand type; calculate the ratio after the conversion based on the number of vehicles with strong electricity demand and the number of vehicles with weak electricity demand after the conversion of the charging demand type.

[0080] In implementation, the pre-change ratio, that is, the ratio between the number of vehicles with weak power demand and the number of vehicles with strong power demand before the charging demand type is converted, reflects the proportion of vehicles with weak power demand to vehicles with strong power demand before the charging demand type is converted.

[0081] Similarly, the post-change ratio, that is, the ratio between the number of vehicles with weak electricity demand and the number of vehicles with strong electricity demand after the charging demand type is converted, reflects the proportion of vehicles with weak electricity demand to vehicles with strong electricity demand after the charging demand type is converted.

[0082] S204: Calculate a ratio change value based on the ratio value after the change and the ratio value before the change.

[0083] In practice, the ratio change value (i.e., the difference between the ratio before and after the change) reflects the change in the proportion of vehicles with low power demand at the charging station before and after the charging demand type change. A larger ratio change value indicates a greater change in the proportion of vehicles with low power demand, and vice versa.

[0084] S205: Compare the ratio change value with a preset ratio comparison value.

[0085] In practice, the preset proportional comparison value is calculated by referring to a large amount of statistical data and electrical equipment operation data in advance, and will not be elaborated on here.

[0086] S206: If the proportional change value is greater than or equal to a preset proportional comparison value, the power grid system is restored to supply power to the vehicles with weak power demand in the charging station one by one.

[0087] In practice, if the proportional change value is greater than or equal to the proportional comparison value, it means that if the grid system restores power to vehicles with weak power demand, it will be noticeable to surrounding users and damage surrounding electrical equipment. Conversely, if the proportional change value is less than the proportional comparison value, it means that if the grid system restores power to vehicles with weak power demand, it will be less noticeable to surrounding users and damage surrounding electrical equipment will be less.

[0088] Therefore, if the proportional change value is greater than or equal to the proportional comparison value, the power supply of the power grid system to vehicles with weak power demand in the charging station will be restored one by one. It is necessary to restore the power supply of the power grid system to vehicles with weak power demand one by one to reduce the perception of surrounding users and reduce the impact of sudden changes in power supply of the power grid system on the normal life and production of surrounding residents.

[0089] The proportional change value is calculated using the following formula:

[0090] ,

[0091] in is the proportional change value, is the number of vehicles with weak electricity demand before the charging demand type conversion, is the number of vehicles with strong electricity demand before the charging demand type conversion, is the ratio before the change, The ratio after the change is calculated. The number before the "-" is the ratio after the change, and the number after the "-" is the ratio before the change. The difference between the two is the ratio change. The numerator of the ratio after the change is increased by one because a vehicle with weak charging demand has been added. Similarly, the denominator of the ratio after the change is decreased by one because a vehicle with strong charging demand has been removed.

[0092] After the numerical comparison in step S205, the following situation is also included: if the proportional change value is less than the proportional comparison value, the power grid system is restored to power the vehicles with weak power demand in the charging station in batches or simultaneously.

[0093] During implementation, since the proportional change value is smaller than the proportional comparison value, even if the power grid system is restored to charge vehicles with weak power demand at the same time, it is difficult for surrounding residents to perceive it. Therefore, the power grid system can be restored to supply power to vehicles with weak power demand in the charging station in batches or at the same time, thereby reducing the operational steps for restoring the power grid system to supply power to vehicles with weak power demand and improving operational efficiency.

[0094] Refer to the attached Figure 3 As shown, restoring the power supply of the power grid system to vehicles with weak power demand in the charging station in batches includes the following processing steps:

[0095] S301 : Calculate a proportion deviation value based on the proportion change value and the proportion comparison value.

[0096] In implementation, the ratio deviation value is the difference between the ratio comparison value and the ratio change value.

[0097] S302: Divide the deviation intervals into multiple deviation intervals for the proportional deviation value according to the preset interval length.

[0098] In implementation, the numerical length of the proportional deviation value is divided into a plurality of deviation intervals according to a preset interval length, so as to facilitate the establishment of a mapping relationship.

[0099] S303: Establish a mapping relationship between a plurality of preset charging recovery quantities and a plurality of deviation intervals.

[0100] In implementation, a corresponding charging recovery quantity is set for each deviation interval, and the charging recovery quantities corresponding to different deviation intervals are different.

[0101] S304 : Match the corresponding deviation interval based on the calculated proportional deviation value.

[0102] In implementation, the deviation interval in which the proportional deviation value is located is matched according to the calculated proportional deviation value.

[0103] S305: Based on the deviation interval, obtain the corresponding charging recovery quantity.

[0104] In implementation, the charging recovery quantity corresponding to the deviation interval is matched according to the above mapping relationship.

[0105] S306. Restore the power grid system in sequence according to the preset interval time, and supply power to a number of vehicles with weak power demand corresponding to the number of restored charging times.

[0106] In practice, once the number of restored charging vehicles corresponding to the proportional deviation value is known, the grid system can be restored sequentially at preset intervals to provide power to a corresponding number of vehicles with weak power demand. For example, in the first batch, the grid system will restore power to m vehicles with weak power demand, followed by another m vehicles with weak power demand in the second batch, and so on, until power is restored to all vehicles with weak power demand.

[0107] If the number of vehicles with weak power demand that need to be restored in the last batch is less than the number of vehicles that can be restored to charge, the power grid system will directly restore power to these vehicles with weak power demand.

[0108] The proportional deviation value is calculated using the following formula:

[0109] ,

[0110] is the proportional deviation value, is the ratio comparison value, The proportional deviation value can be obtained by subtracting the proportional change value from the proportional comparison value.

[0111] Before a vehicle with high power demand in the charging state reaches the charging threshold, if the user changes the charging demand type of the vehicle with high power demand in the charging state to low power demand or stops charging, the power grid system will resume power supply to the vehicle with low power demand in the charging station.

[0112] Before a vehicle with strong power demand in the charging state reaches the charging threshold, if the user changes the charging demand type of the vehicle with strong power demand in the charging state to weak power demand or stops charging through the mobile terminal, it means that the user's charging demand has weakened or there is no charging demand, and there is no need to provide a charging mode with strong charging demand for the user's car. At this time, the power grid system is directly restored to supply power to vehicles with weak power demand in the charging station, thereby speeding up the charging speed of other vehicles.

[0113] Before a vehicle with high power demand in the charging state reaches the charging threshold, if the charging station cannot receive power supply from the power grid system, the power supply in the charging pile corresponding to the vehicle will be controlled to charge the vehicle.

[0114] If a high-power-demand vehicle in the charging state has not reached the charging threshold and a power outage, equipment maintenance, or other phenomena occur, causing the charging station to be unable to receive power from the power grid system, the power supply in the charging pile corresponding to the vehicle will be controlled to charge the vehicle so that the vehicle can be replenished with power in a timely manner.

[0115] If the electric energy released by the power source in the charging pile corresponding to the vehicle does not cause the vehicle to reach the charging threshold, the vehicle is matched with other charging piles to charge the vehicle.

[0116] If the electric energy released by the charging pile currently used by the vehicle does not cause the vehicle to reach the charging threshold, other charging piles will be matched for the vehicle to charge the vehicle. The matched charging pile will travel to the location of the vehicle and continue to charge the vehicle to extend the vehicle's range and improve the user experience.

[0117] The embodiments of this specific implementation method are all preferred embodiments of the present application and are not intended to limit the scope of protection of the present application in turn. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
