Description

Technical Field

[0001] The present invention relates to the field of electric vehicles, and in particular to a method and device for optimizing the selection of a fast charging pile, and a computer-readable storage medium. Background Art

[0002] With the increasing popularity of electric vehicles, charging has become a common problem for users. Currently, based on backend data collected about the usage of charging piles at each charging station, users can query the location and number of available charging piles for their electric vehicles and drive to them for charging. During fast charging, the power battery management system outputs a fast-charge request current signal to the fast-charging pile based on the actual charging capacity of the battery. The fast-charging pile then outputs the actual charging current based on the request current value.

[0003] However, since some fast charging piles will reduce the output actual charging current by a certain ratio after receiving the fast charging request current signal value, the actual charging current will be far lower than the requested current. Charging on this type of current-limited fast charging pile will cause problems such as poor fast charging effect and long charging time, leading to user complaints. Summary of the Invention

[0016] Determining whether the first current value and the second current value conform to a preset logic within a preset time;

[0017] If the first current value and the second current value meet the preset logic a preset number of times within the preset time, the fast charging pile is determined to be a current-limited fast charging pile;

[0018] If the first current value and the second current value do not conform to the preset logic within the preset time, or the number of times the first current value and the second current value conform to the preset logic within the preset time does not reach the preset number, the fast charging pile is not determined to be a current-limited fast charging pile.

[0019] Optionally, after the step of determining whether the first current value and the second current value conform to a preset logic within a preset time, the method further comprises:

[0020] If the first current value and the second current value conform to a preset logic within a preset time, a counting mark is added to the fast charging pile;

[0023] Refresh the counting mark of the fast charging pile, obtain the number of the counting marks, and determine whether the number of the counting marks reaches a preset upper limit;

[0024] If the number of the counting marks reaches a preset upper limit, the fast charging pile is determined to be a current-limiting fast charging pile, and the step of recording the serial number of the current-limiting fast charging pile is executed.

[0025] Optionally, after the step of determining whether the number of the counting marks reaches a preset upper limit, the method further comprises:

[0036] It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0037] The main solution of the embodiment of the present invention is: a method for optimizing the selection of a fast charging pile, which includes the following steps:

[0038] When the preset conditions are met, locate the number and position of the fast charging pile;

[0039] Determining whether the fast charging pile is a current-limiting fast charging pile;

[0040] If the fast charging pile is a current-limiting fast charging pile, record the number of the current-limiting fast charging pile;

[0041] When an instruction to select a fast charging pile is received from the client, the current-limiting fast charging pile is automatically filtered according to the number of the current-limiting fast charging pile.

[0042] With the increasing popularity of electric vehicles, charging has become a common problem for users. Currently, based on backend data collected about the usage of charging piles at each charging station, users can query the location and number of available charging piles for their electric vehicles and drive to them for charging. During fast charging, the power battery management system outputs a fast-charge request current signal to the fast-charging pile based on the actual charging capacity of the battery. The fast-charging pile then outputs the actual charging current based on the request current value.

[0043] However, since some fast charging piles will reduce the output actual charging current by a certain ratio after receiving the fast charging request current signal value, the actual charging current will be much lower than the requested current. Charging on this type of current-limited fast charging pile will cause problems such as poor fast charging effect and long charging time, leading to user complaints.

[0044] The present invention provides a fast charging pile selection optimization method. When preset conditions are met, the method determines whether the fast charging pile is a current-limiting fast charging pile by locating the number and position of the fast charging pile. If the fast charging pile is a current-limiting fast charging pile, the number of the current-limiting fast charging pile is recorded, thereby ensuring accurate positioning and reducing the misjudgment rate of the current-limiting fast charging pile. When an instruction to select a fast charging pile is received from a client, the current-limiting fast charging pile is automatically filtered according to the number of the current-limiting fast charging pile, thereby avoiding the risk of the user using the current-limiting fast charging pile in advance, realizing the optimization of the selection of the fast charging pile, improving the fast charging efficiency, preventing users from complaining about slow fast charging, and improving the user's car experience.

As a type of motion sensor, the gravity acceleration sensor can detect the magnitude of acceleration in all directions (generally three axes), and can detect the magnitude and direction of gravity when stationary. It can be used for applications that identify the posture of the mobile terminal (such as horizontal and vertical screen switching, related games, magnetometer posture calibration), vibration recognition related functions (such as pedometer, tapping), etc.; of course, the mobile terminal can also be configured with other sensors such as gyroscopes, barometers, hygrometers, thermometers, infrared sensors, etc., which will not be repeated here.

[0065] If the first current value and the second current value meet the preset logic a preset number of times within the preset time, the fast charging pile is determined to be a current-limited fast charging pile;

[0066] If the first current value and the second current value do not conform to the preset logic within the preset time, or the number of times the first current value and the second current value conform to the preset logic within the preset time does not reach the preset number, the fast charging pile is not determined to be a current-limited fast charging pile.

[0067] Furthermore, the processor 1001 may call the fast charging pile selection optimization program stored in the memory 1005 and perform the following operations:

[0076] Obtain the filtered location information of the recommended fast charging piles within a preset distance of the client, and send the location information of the recommended fast charging piles to the client.

[0077] Reference Figure 2 A first embodiment of the present invention provides a method for optimizing the selection of a fast charging pile, the method comprising:

[0078] Step S10: When the preset conditions are met, locate the number and position of the fast charging pile;

[0079] In this embodiment, step S10 includes:

[0080] When it is detected that the fast charging gun is inserted into the electric vehicle, the fast charging pile has actual output, and the battery power of the electric vehicle is within the preset power range, the number and position of the fast charging pile are located.

[0081] It should be noted that, in this embodiment, the executing entity is a cloud platform server capable of big data collection and analysis, hereinafter referred to as the background; the preset condition is "monitoring that the fast charging gun is inserted into the electric vehicle, and the fast charging pile has actual output, and the battery power of the electric vehicle is within the preset power range". In this embodiment, the preset power range is 30% to 80%. At this time, the battery of the electric vehicle has a greater fast charging capability, which is convenient for monitoring. The preset power range can also be other reasonable ranges, such as 20% to 60%, 40% to 70%, etc. Depending on the vehicle battery, the power range with greater fast charging capability will also be different, and this embodiment does not limit this.

[0082] It is understandable that since the background can collect and analyze data based on big data, when the background monitors the fast charging pile that meets the above preset conditions based on big data, it means that the fast charging pile has started charging the electric vehicle. Only then is it necessary to detect the charging efficiency. If any of the above conditions is missing, it means that the fast charging pile has not charged the electric vehicle, so there is no need to monitor the fast charging pile in real time.

[0083] In this embodiment, step S10 includes:

[0084] Obtaining a fast charging request signal sent by the electric vehicle to the fast charging pile, and obtaining a first current value according to the fast charging request signal;

[0085] The second current value output by the fast charging pile is detected in real time.

[0086] It can be understood that during the fast charging process of an electric vehicle, the power battery management system will output a fast charging request current signal to the fast charging pile based on the actual charging capacity of its own battery. The first current value is the request current value obtained based on the fast charging request current signal, and the second current value is the actual charging current output by the fast charging pile with reference to the request current value.

[0087] Step S20, determining whether the fast charging pile is a current-limiting fast charging pile;

[0088] It can be understood that when it is determined that the currently located fast charging pile is fast charging the power battery of an electric vehicle, and the requested current value of the electric vehicle and the actual charging current output by the fast charging pile are obtained, the two current values can be compared to determine whether the fast charging pile is a current-limited fast charging pile.

[0089] Step S30: If the fast charging pile is a current-limiting fast charging pile, record the number of the current-limiting fast charging pile;

[0090] It can be understood that after the judgment in step S20, a conclusion can be obtained as to whether the fast charging pile is a current-limiting fast charging pile. If the fast charging pile is a current-limiting fast charging pile, the number of the current-limiting fast charging pile is recorded; if the fast charging pile is not a current-limiting fast charging pile, the process returns to step S10 and continues to monitor the conditions of other fast charging piles that meet the preset conditions.

[0091] Step S40: When receiving an instruction from the client to select a fast charging pile, the current-limiting fast charging pile is automatically filtered according to the number of the current-limiting fast charging pile.

[0092] It should be noted that the client may be an onboard computer of an electric vehicle or a mobile APP used by a user driving the electric vehicle, and this embodiment does not impose any restrictions on this.

[0093] It is understandable that when a user needs to charge, he will search for the location of a nearby fast charging pile. At this time, the background will receive a request from the user via the client to obtain the location of a nearby fast charging pile, and filter the various current-limiting fast charging piles among the fast charging piles near the user according to the number of the recorded current-limiting fast charging piles.

[0094] In this embodiment, the steps after step S40 include:

[0095] Obtain the filtered location information of the recommended fast charging piles within a preset distance of the client, and send the location information of the recommended fast charging piles to the client.

[0096] It should be noted that the preset distance may be 5 kilometers near the client, or 3 kilometers near the client, or other reasonable distances, which is not limited in this embodiment.

[0097] It is understandable that after filtering the information of the current-limited fast charging piles, the background will obtain the location information of other fast charging piles within a preset distance near the client, and send the location information of these fast charging piles to the user for the user to choose.

[0098] In the specific implementation, the background will send the location of the fast charging pile near the client to the user, and reflect the current-limited fast charging pile on the map as a highlighted warning with 5 counting marks, and the counting marks of the remaining fast charging piles are also reflected on the map, and different colors or text labels are given according to the number of counting marks. For example, the fast charging pile with 0 counting mark is displayed in green, and the text label is recommended; the background can also filter the current-limited fast charging piles directly from the map, that is, the fast charging piles sent to the user do not include the current-limited fast charging piles.

[0099] This embodiment proposes a fast charging pile selection optimization method. In the fast charging pile selection optimization method, when the preset conditions are met, the number and position of the fast charging pile are located to determine whether the fast charging pile is a current-limiting fast charging pile. If the fast charging pile is a current-limiting fast charging pile, the number of the current-limiting fast charging pile is recorded, thereby ensuring accurate positioning and reducing the misjudgment rate of the current-limiting fast charging pile. When an instruction to select a fast charging pile is received from the client, the current-limiting fast charging pile is automatically filtered according to the number of the current-limiting fast charging pile, thereby avoiding the risk of users using current-limiting fast charging piles in advance, realizing the optimization of fast charging pile selection, improving fast charging efficiency, preventing users from complaining about slow fast charging, and improving the user's car experience.

[0100] Further, refer to Figure 3 , proposes the second embodiment of the fast charging pile selection optimization method of the present invention, based on the above Figure 2 In the embodiment shown, step S20 includes:

[0101] Step S21 , determining whether the first current value and the second current value conform to a preset logic within a preset time.

[0102] It should be noted that, in this embodiment, not only one fast charging pile for charging electric vehicles is monitored all the time, but multiple fast charging piles that meet the above preset conditions are monitored at the same time, and for each monitored fast charging pile, a judgment on whether to limit the current is made within a short time; the preset time is 1 minute, and it can also be other reasonable monitoring times such as 30 seconds, 1 minute and 30 seconds, 45 seconds, etc., which is not limited in this embodiment; the logic is: fast charging request current ÷ | actual charging current | > 2.

[0103] It can be understood that in this embodiment, when the quotient of the absolute value of the fast charging request current and the actual charging current is greater than 2 and maintained for 1 minute, it is considered that the first current value and the second current value comply with the preset logic within the preset time.

[0104] In the specific implementation, for example: the fast charging request current is 400A, the actual charging current is 150A, if the actual charging current does not reach or exceed 200A within 1 minute, it is obviously in line with the preset logic; for another example: the fast charging request current is 300A, the actual charging current is 100A, if the actual charging current does not reach or exceed 150A within 1 minute, it is obviously in line with the preset logic.

[0105] Step S21 and subsequent steps include:

[0106] Step S22: If the first current value and the second current value conform to a preset logic within a preset time, a counting mark is added to the fast charging pile;

[0107] Step S23: If the first current value and the second current value do not conform to a preset logic within a preset time, a counting mark of the fast charging pile is reduced by one, wherein the number of the counting marks will not be less than 0.

[0108] It can be understood that when judging whether the relationship between two current values conforms to the preset logic, the background will start the counting mark function. When it conforms to the preset logic, the fast charging pile will be counted and marked with +1, and the fast charging count will stop; when it does not conform to the preset logic, the fast charging pile will be counted and marked with -1. The minimum number of counting marks for each fast charging pile is 0, and the fast charging count will stop.

[0109] Step S22 and step S23 include:

[0110] Step S24: Refresh the counting mark of the fast charging pile, obtain the number of the counting marks, and determine whether the number of the counting marks reaches a preset upper limit.

[0111] Step S24 and subsequent steps include:

[0112] Step S25: If the number of the counting marks does not reach the preset upper limit, return to step S10: when the preset conditions are met, locate the number and position of the fast charging pile;

[0113] In step S26 , if the number of the counting marks reaches a preset upper limit, the fast charging pile is identified as a current-limiting fast charging pile, and step S30 is executed: the serial number of the current-limiting fast charging pile is recorded.

[0114] It should be noted that the counting mark is used to record the number of times the fast charging pile has current limiting phenomenon, but each fast charging pile may occasionally have current limiting output, so it is not determined that the fast charging pile is a current limiting fast charging pile after counting once, but it is determined after multiple counts. In this embodiment, the upper limit of the preset number is 5, and it can also be set to other values, such as 4, 6, etc., which is not limited in this embodiment.

[0115] It is understood that after the fast charge count stops, the count mark of the fast charge pile will be refreshed and the latest count mark of the fast charge pile will be obtained. If the latest count does not reach the preset upper limit, the monitoring of the current fast charge pile will end and the monitoring of other fast charge piles will continue, that is, returning to step S10; however, if the latest count reaches the preset upper limit, it means that the fast charge pile has experienced current limiting output multiple times. At this time, the fast charge pile is identified as a current limiting fast charge pile, and the location and number of the current limiting fast charge pile need to be recorded, that is, executing step S30.

[0116] In this embodiment, detailed steps for determining whether the fast charging pile is a current-limiting fast charging pile in the fast charging pile selection optimization method are given, by determining whether the first current value and the second current value comply with the preset logic within the preset time. If the first current value and the second current value comply with the preset logic within the preset time, a counting mark is added to the fast charging pile; if the first current value and the second current value do not comply with the preset logic within the preset time, a counting mark is reduced for the fast charging pile; the counting mark of the fast charging pile is refreshed, and the number of the counting marks is obtained. If the number of the counting marks does not reach the preset upper limit, return to step: when the preset conditions are met, locate the number and position of the fast charging pile; if the number of the counting marks reaches the preset upper limit, determine that the fast charging pile is a current-limiting fast charging pile, and execute step S30: record the number of the current-limiting fast charging pile, and detect and judge the charging current situation of the fast charging pile when it is used in a short period of time multiple times, thereby reducing the probability of misjudgment of the current limiting phenomenon.

[0117] In addition, an embodiment of the present invention further provides a computer-readable storage medium, on which a fast charging pile selection optimization program is stored. When the fast charging pile selection optimization program is executed by a processor, the following operations are implemented:

[0118] When the preset conditions are met, locate the number and position of the fast charging pile;

[0119] Determining whether the fast charging pile is a current-limiting fast charging pile;

[0120] If the fast charging pile is a current-limiting fast charging pile, record the number of the current-limiting fast charging pile;

[0121] When an instruction to select a fast charging pile is received from the client, the current-limiting fast charging pile is automatically filtered according to the number of the current-limiting fast charging pile.

[0122] Furthermore, when the processor executes the fast charging pile selection optimization program, the following operations are also implemented:

[0123] When the preset conditions are met, the step of locating the number and position of the fast charging pile includes:

[0124] When it is detected that the fast charging gun is inserted into the electric vehicle, the fast charging pile has actual output, and the battery power of the electric vehicle is within the preset power range, the number and position of the fast charging pile are located.

[0125] Furthermore, when the processor executes the fast charging pile selection optimization program, the following operations are also implemented:

[0126] Obtaining a fast charging request signal sent by the electric vehicle to the fast charging pile, and obtaining a first current value according to the fast charging request signal;

[0127] The second current value output by the fast charging pile is detected in real time.

[0128] Furthermore, when the processor executes the fast charging pile selection optimization program, the following operations are also implemented:

[0129] The step of determining whether the fast charging pile is a current-limiting fast charging pile includes:

[0130] Determining whether the first current value and the second current value conform to a preset logic within a preset time;

[0131] If the first current value and the second current value meet the preset logic a preset number of times within the preset time, the fast charging pile is determined to be a current-limited fast charging pile;

[0132] If the first current value and the second current value do not conform to the preset logic within the preset time, or the number of times the first current value and the second current value conform to the preset logic within the preset time does not reach the preset number, the fast charging pile is not determined to be a current-limited fast charging pile.
