[0047] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0048] The core contradiction currently faced in the field of new energy vehicle charging is that the limited charging facility resources and long charging duration are difficult to meet the growing charging demands of electric vehicles. In this process, the following prominent problems generally exist:

[0049] First, some vehicles that have completed charging occupy the charging pile for a long time because the vehicle owners fail to remove the charging gun in time, thus affecting the normal use of other vehicles in urgent need of charging.

[0050] Second, the charging period of electric vehicles highly coincides with the peak period of urban electricity consumption, which not only exacerbates the operation pressure of the power grid but also poses a severe challenge to the overall power load management of the city.

[0051] Based on this, a vehicle charging control method and device provided by the embodiments of the present invention can enable each vehicle entering the charging station to charge in time and ensure the safety of the power grid load.

[0052] To facilitate the understanding of this embodiment, first, a detailed introduction to the application scenario of a vehicle charging control method disclosed in the embodiments of the present invention will be given.

[0053] Figure 1 It is a schematic diagram of the application scenario of a vehicle charging control method provided by the embodiments of the present invention.

[0054] As Figure 1 shown, the camera installed at the entrance of the charging station identifies the vehicle and captures pictures of each entering vehicle. The background server identifies the vehicle pictures. At the same time, the background server applies the vehicle charging control method provided by the embodiments of the present invention to determine the target charging pile for each vehicle entering the charging station, sort the vehicles waiting to be charged in each charging pile, and control the charging mode and charging current of the charging vehicles.

[0055] Among them, the specific vehicle charging control method is as Figure 2 shown. This method is applied to the background server and includes the following steps:

[0056] Step S102: Identify based on the captured images of the vehicles to be charged in the charging station in sequence, and determine the vehicle models and estimated charging capacities of the vehicles to be charged in sequence.

[0057] Here, the vehicle models of the vehicles to be charged in sequence can be determined by identifying the images. Each vehicle model is pre-corresponded with an estimated charging capacity, which can be understood as the maximum chargeable capacity of the vehicle of this model.

[0058] Step S104: Determine the target charging piles corresponding to the vehicles to be charged in sequence according to the charging information of the vehicles charged in sequence corresponding to each charging pile in the charging station.

[0059] Among them, the charging information includes the number of vehicles charged in sequence and the actual charging capacities to be charged of each vehicle charged in sequence; based on the charging information, it can be known whether the available capacity of each charging pile can meet the requirements of the vehicles to be charged in sequence and the approximate waiting time of the vehicles to be charged in sequence, and the charging duration of the vehicles to be charged in sequence can be roughly known, so as to determine the target charging pile with the shortest duration.

[0060] Step S106: When the vehicle to be charged in sequence inserts the charging gun into the target charging pile, update the charging order of the vehicle to be charged in sequence after inserting it into the target charging pile based on the current grid load information, the user's desired charging completion time, and the actual charging capacity to be charged of the vehicle to be charged in sequence sent by the target charging pile.

[0061] After the vehicle to be charged in sequence inserts into the target charging pile, the background server can know the actual charging capacity (less than or equal to the estimated charging capacity) of the vehicle to be charged in sequence and the user's desired charging completion time (pick-up time) of the desired charging completion, and combined with the grid load, can update the charging order of adding the vehicle to be charged in sequence to the target charging pile.

[0062] Step S108: In the case of the grid being at the peak or trough of power consumption, control the target vehicle being charged in the current order to adjust the charging mode and / or charging power based on the current grid load information.

[0063] During the real-time charging process, if the corresponding grid load status is monitored, control the charging mode and / or charging power of the corresponding vehicles being charged at each charging pile to ensure the stability of the grid load.

[0064] In a preferred embodiment of the actual application, by identifying the images collected of the appearance of the vehicles entering the charging station, the vehicle model of the vehicle to be charged in the charging queue and the maximum charging capacity corresponding to the model can be obtained; then, according to the number of vehicles in the charging queue state in each charging pile and the charging capacity required by the vehicles, the target charging pile that can meet the maximum charging capacity requirement can be determined; when the vehicle to be charged in the charging queue inserts the charging gun into the target charging pile, the actual charging information of the vehicle to be charged in the charging queue can be obtained, and then, in combination with the current grid load, the charging order after the vehicle to be charged in the charging queue inserts into the target charging pile can be updated; in the case where the grid load is monitored to be at the peak or trough, the corresponding target vehicle in the current charging order is controlled to adjust the charging mode and / or charging power to ensure the stability of the grid load.

[0065] As an alternative implementation manner, step S102 can identify the vehicle model and the corresponding estimated charging capacity to be charged in the following ways, including:

[0066] Step 1.1, based on the AI image recognition algorithm, determine the vehicle model of the vehicle to be charged in the charging queue from the collected images.

[0067] Among them, the collected images are the appearance images of the vehicles to be charged in the charging queue collected by the entrance camera of the charging station, and the background server performs image recognition on the obtained appearance images of each vehicle to be charged in the charging queue, and can identify the vehicle model corresponding to each vehicle appearance through the AI recognition method.

[0068] Step 1.2, based on the vehicle model, find the estimated charging capacity corresponding to the vehicle to be charged in the charging queue.

[0069] Here, the estimated charging capacity corresponding to each vehicle model can be recorded and stored in advance. At this time, the background server can call out the estimated charging capacity of the corresponding vehicle to be charged in the charging queue based on the identified vehicle model.

[0070] In some embodiments, step S104 can select the charging pile that meets the requirements of the estimated charging capacity of the vehicle to be charged in the charging queue and has the shortest charging time as the target charging pile, specifically including:

[0071] Step 2.1, according to the number of vehicles that have been charged in the charging queue corresponding to each charging pile in the charging station and the actual charging capacity to be charged of each vehicle that has been charged in the charging queue, determine the available charging capacity and charging time of each charging pile.

[0072] Among them, the product of the number of charged and sorted vehicles corresponding to each charging pile and the actual remaining charging capacity of each charged and sorted vehicle can be used to know the supply capacity of each charging pile; then, by combining the difference between the supply capacity and the total capacity of the charging pile, the available charging capacity of each charging pile can be obtained; at the same time, based on the charging time of each charged and sorted vehicle and the number of charged and sorted vehicles corresponding to each charging pile, the remaining charging time corresponding to each charging pile can be obtained; that is, the latest time for the current remaining charging and sorted vehicle to start the charging operation is after this remaining charging time.

[0073] Step 2.2: Compare the available charging capacity of each charging pile with the estimated remaining charging capacity to determine the first charging pile that can meet the charging requirements of the remaining charging and sorted vehicles.

[0074] Here, the charging piles with available charging capacity greater than the estimated remaining charging capacity are included in the selection range of the target charging piles.

[0075] Step 2.3: Based on the remaining charging time, determine the target charging pile with the shortest required charging time for the remaining charging and sorted vehicles from the first charging piles.

[0076] Then, select the charging pile with the shortest remaining charging time from the first charging piles as the target charging pile.

[0077] On the basis of the foregoing embodiments, after the remaining charging and sorted vehicle arrives at the target charging pile and inserts the charging gun, the background server can obtain the actual charging information of the remaining charging and sorted vehicle, and then, in combination with the grid compliance information, determine the charging order of the remaining charging and sorted vehicle at the target charging pile; specifically, this step S106 includes:

[0078] Step 3.1: When the remaining charging and sorted vehicle inserts the charging gun at the target charging pile, obtain the user's expected completion charging time and the actual remaining charging capacity of the remaining charging and sorted vehicle sent by the target charging pile.

[0079] Among them, after the remaining charging and sorted vehicle inserts the charging gun, the target charging pile only reads the basic vehicle information (actual battery status, actual remaining power capacity, SOC, maximum charging current, etc.) according to the national standard protocol and transmits these basic information to the background server; at the same time, the background server obtains the expected pick-up time provided by the vehicle owner (the user's expected completion charging time).

[0080] It should be noted that the user can input information such as the expected charging completion time through the interactive device configured on the charging pile or the user's intelligent control device; the user can also directly transmit information such as the expected charging completion time and vehicle model to the background server through the intelligent control device. The background server searches for the target charging pile corresponding to the vehicle to be charged in the waiting charging queue based on information such as the expected charging completion time and vehicle model of the user, and then combines the vehicle basic information sent by the target charging pile, etc., to update the charging order in the subsequent steps.

[0081] Step 3.2, based on the current grid load information, the actual waiting charging capacity of the vehicle to be charged in the waiting charging queue, the user's expected charging completion time, and the charging order of the charged vehicles corresponding to the target charging pile, update the charging order to the latest charging order after the vehicle to be charged in the waiting charging queue is inserted into the target charging pile according to the recursive incremental algorithm.

[0082] Here, by using the recursive incremental algorithm, it is not necessary to recalculate the charging order of the target charging pile where the vehicle to be charged in the waiting charging queue is added, but only to update the charging order of the target charging pile based on the current grid load and the charging information of the newly added vehicle to be charged in the waiting charging queue.

[0083] In practical applications, step S108 also monitors the grid load status, and controls the corresponding vehicles in the current charging order to adjust the charging mode and / or charging power in the case of power peaks or valleys of the power grid, so as to ensure the stability of the grid load, specifically including:

[0084] Step 4.1, if it is determined based on the current grid load information that the power grid is in a power peak or power valley, then determine the power value to be adjusted for the charging station according to the difference between the power outputtable by the power grid corresponding to the current grid load information and the charging power required by the vehicles charging in the current order in the charging station.

[0085] Here, based on the current grid load information, the background server can know whether it is currently in a power peak or power valley from the preset grid load curve; if it is in a power peak or power valley, then according to the comparison difference between the power outputtable by the power grid under the corresponding load status and the charging power required by the vehicles currently charging in the charging station, determine the power value to be reduced for the charging station in the case of a power peak and the power value that can be increased for the charging station in the case of a power valley.

[0086] Step 4.2, according to the charging status of each vehicle charging in the current order, the user's expected charging completion time and charging current value, and the corresponding weight coefficients respectively, determine the arrangement order of each vehicle charging in the current order in the case of a power peak or power valley.

[0087] Exemplarily, the vehicles can be sorted according to the comprehensive situation of multiple charging parameters of the vehicle currently being charged to ensure that the subsequent steps adjust the vehicles according to this order, including:

[0088] Step 4.2.1: Determine the comprehensive score of each currently sequenced charging vehicle according to the charging state corresponding to the first weight coefficient, the user's expected completion charging time corresponding to the second weight coefficient, and the charging current value corresponding to the third weight coefficient.

[0089] Here, the charging state of the currently sequenced charging vehicle, the user's expected completion charging time, and the charging current value respectively correspond to a weight coefficient, which can be preset in advance or adjusted by the background server according to the actual situation.

[0090] Step 4.2.2: In the case of a power peak, control the arrangement order of the currently sequenced charging vehicles with a charging state closer to completion, a longer user's expected completion charging time, and a larger charging current value in the comprehensive score to be in the front.

[0091] It can be understood that when the completion percentage of the charging state is higher, that is, the charging state is closer to completion; the longer the current time is from the user's expected completion charging time, the longer the user's expected completion charging time; in the case of a power peak, when the charging state of a vehicle is closer to completion, the user's expected completion charging time is longer, and the charging current value is larger, its corresponding comprehensive score is higher, and the arrangement order is more forward.

[0092] Step 4.2.3: In the case of a power valley, control the arrangement order of the currently sequenced charging vehicles with a charging state farther from completion, a closer user's expected completion charging time, and a smaller charging current value in the comprehensive score to be in the front.

[0093] Similarly to the above, when the completion percentage of the charging state is lower, that is, the charging state is farther from the completion state; the shorter the current time is from the user's expected completion charging time, the closer the user's expected completion charging time; in the case of a power valley, when the charging state of a vehicle is farther from completion, the user's expected completion charging time is closer, and the charging current value is smaller, its corresponding comprehensive score is higher, and the arrangement order is more forward.

[0094] Step 4.3: Based on the power value to be adjusted, determine at least one target vehicle to be adjusted in the case of a power peak or a power valley from the currently sequenced charging vehicles with a forward arrangement order.

[0095] Here, according to the power value to be adjusted, select the corresponding number of target vehicles in the arrangement order for adjustment to meet the situation of a power peak or a power valley.

[0096] Step 4.4, based on the charging status of each target vehicle, the user's desired time to complete charging, and the charging current value, allocate an adjustable power value to each target vehicle.

[0097] As an alternative embodiment, in the case of a power peak, if the charging status of a certain target vehicle is closer to completion, the user's desired time to complete charging is longer, and the charging current value is larger, then the adjustable power value allocated to this target vehicle is larger; in the case of a power valley, if the charging status of a certain target vehicle is farther from completion, the user's desired time to complete charging is closer, and the charging current value is smaller, then the adjustable power value allocated to this target vehicle is larger.

[0098] Step 4.5, based on the allocated adjustable power value, the charging status of each target vehicle, the user's desired time to complete charging, and the charging current value, control each target vehicle to adjust the charging current and / or charging mode.

[0099] Here, based on the allocated adjustable power value in the foregoing embodiment and the charging information of each target vehicle, it is possible to further control the charging current and / or charging mode of each target vehicle, specifically including:

[0100] Step 4.5.1, in the case of a power peak, based on the allocated adjustable power value of each target vehicle, adjust the target vehicle whose charging status meets the first preset requirement for distance from completion from the constant current charging mode to the trickle charging mode, and control the target vehicle whose charging current value reaches the first preset current threshold or whose user's desired time to complete charging exceeds the first preset time threshold to reduce the charging current.

[0101] Among them, the target vehicle whose charging status meets the first preset requirement for distance from completion can be understood as a vehicle that is about to complete charging. At this time, the charging power can be adjusted by adjusting the charging mode; the target vehicle whose charging current value reaches the first preset current threshold can be understood as a vehicle with a relatively large charging current value, and the target vehicle whose user's desired time to complete charging exceeds the first preset time threshold can be understood as a vehicle with a relatively long user's desired time to complete charging (far from the pick-up time). For these two types of target vehicles, the charging power can be adjusted by reducing the charging current.

[0102] Step 4.5.2, in the case of a power valley, based on the allocated adjustable power value of each target vehicle, control the target vehicle whose charging status meets the second preset requirement for distance from completion to the constant current charging mode, and control the target vehicle whose charging current value does not reach the second preset current threshold or whose user's desired time to complete charging does not exceed the second preset time threshold to increase the charging current.

[0103] Among them, the target vehicle whose charging state is close to completion and meets the second preset requirement can be understood as a vehicle that has just started charging not long ago. At this time, the charging power can be adjusted by adjusting the charging mode; the charging current value that has not reached the second preset current threshold can be understood as a vehicle with a small charging current value, and the vehicle whose user's expected charging completion time does not exceed the second preset time threshold can be understood as a vehicle with a short expected charging completion time (close to the vehicle pick-up time). For these two types of target vehicles, the charging power can be adjusted by increasing the charging current.

[0104] Among them, the percentage value corresponding to the second preset requirement is less than or equal to the percentage value corresponding to the first preset requirement; the second preset current threshold is less than or equal to the first preset current threshold; the second preset time threshold is less than or equal to the first preset time threshold.

[0105] In the embodiment of the present invention, the AI recognition camera is used to obtain the vehicle image to determine the vehicle model and the maximum chargeable capacity to be charged, and then the target charging pile that can meet the supply is determined. Combining the grid load information, the recursive incremental clustering algorithm is applied to reasonably sort the vehicle charging. While realizing the reasonable utilization of the charging pile, it has a long-term effect of balancing the grid usage load.

[0106] In some embodiments, as Figure 3 shown, the embodiment of the present invention also provides a vehicle charging control device 200, including:

[0107] The first determination module 201 is used to identify based on the collected image of the vehicle to be charged and sorted entering the charging station, and determine the vehicle model and the estimated chargeable capacity of the vehicle to be charged and sorted.

[0108] The second determination module 202 is used to determine the target charging pile corresponding to the vehicle to be charged and sorted according to the charging information of the charged and sorted vehicles corresponding to each charging pile in the charging station; wherein, the charging information includes the number of the charged and sorted vehicles and the actual chargeable capacity of each charged and sorted vehicle.
