Description

Technical Field

[0001] The present application relates to the technical field of charging device design, and in particular to a cable parameter determination method, charging device, apparatus, equipment, medium and product. Background Art

[0002] With the popularity of electric vehicles, the design and optimization of charging equipment has become increasingly important. However, in the related art, the outlet position of the charging cable of the charging equipment is random. In order to meet the charging needs of charging points at different positions on the parking space, a cable length compensation mechanism is usually set to solve the problem of insufficient cable length at distant charging points. Although the charging demand has been solved to a certain extent, the outlet position of the charging cable has not been reasonably designed, which may lead to the situation that a longer cable length is required to meet the charging needs of different charging points at the same time due to unreasonable outlet position, and the utilization rate of the cable length is low. Summary of the invention

[0003] The embodiments of the present application provide a cable parameter determination method, charging device, apparatus, equipment, medium and product, which can determine a more reasonable outlet position of a charging cable in a charging device to improve the utilization rate of the cable length.

[0004] In a first aspect, an embodiment of the present application provides a cable parameter determination method, which is applied to a charging device, wherein the charging device includes a body, a charging gun, and a charging cable connecting the body and the charging gun. The cable parameters include an outlet position, which is a position where the charging cable extends out of the body. The method includes:

[0005] Acquire a first position of the charging device relative to the parking space, at least one charging point of the parking space, and a plurality of candidate outlet positions of the charging device;

[0006] Determining at least one candidate cable length between each candidate outlet location and at least one charging point location based on the first location;

[0007] For each candidate outlet position, determining the maximum value of at least one candidate cable length as a first cable length corresponding to each candidate outlet position;

[0008] The candidate outlet position corresponding to the minimum value among the plurality of first cable lengths is determined as the outlet position.

[0009] In this way, by obtaining the first position of the charging device relative to the parking space, at least one charging point of the parking space, and multiple candidate outlet positions of the charging device, the candidate cable length between each candidate outlet position and at least one charging point can be calculated, and the maximum value of these lengths can be used as the first cable length corresponding to each candidate outlet position to ensure that the charging needs of charging points at different positions can be met. Then, the candidate outlet position corresponding to the minimum value of these first cable lengths is determined as the final outlet position, so as to reasonably select the outlet position, reduce the required cable length while meeting the charging needs of charging points at different positions, and improve the utilization rate of the cable length.

[0010] In some embodiments, when there are multiple charging points, determining at least one candidate cable length between each candidate outlet position and at least one charging point according to the first position includes:

[0011] Determine at least one target charging point from a plurality of charging points according to the first position;

[0012] At least one candidate cable length between each candidate outlet position and at least one target charging point is determined according to the first position.

[0013] In this way, when there are multiple charging points, we can first determine the more frequently used charging point as the target charging point based on the first position of the charging equipment relative to the parking space to participate in the subsequent candidate cable length calculation, avoiding the calculation of the candidate cable lengths corresponding to all charging points, so as to save computing resources.

[0014] In some embodiments, determining at least one target charging point from a plurality of charging points according to the first position includes:

[0015] Determining a charging path between the first location and each charging point;

[0016] The charging point whose charging path meets the preset conditions is determined as the target charging point.

[0017] In this way, by determining the charging path between the first position of the charging device and each charging point, the charging points that meet the preset conditions are screened out as target charging points, avoiding the calculation of the candidate cable lengths corresponding to all charging points, so as to achieve the purpose of saving computing power resources.

[0018] In some embodiments, the at least one charging point includes a first charging point, a second charging point, a third charging point, and a fourth charging point, wherein the first charging point corresponds to the position of the charging port at the front left side of the vehicle, the second charging point corresponds to the position of the charging port at the rear left side of the vehicle, the third charging point corresponds to the position of the charging port at the rear right side of the vehicle, and the fourth charging point corresponds to the position of the charging port at the front of the vehicle;

[0019] Determining at least one target charging point from at least one charging point according to the first position includes:

[0020] When the first position is located at one side in the length direction of the parking space, the first charging point, the second charging point, the third charging point and the fourth charging point are determined as target charging points.

[0021] In this way, by considering the specific location of the charging equipment in the parking space and determining the corresponding target charging point, the outlet position is reasonably selected based on this, so that the length of the charging cable can meet the needs of different charging points, thereby improving the utilization rate of the cable length.

[0022] In some embodiments, the at least one charging point includes a first charging point, a second charging point, a third charging point, and a fourth charging point, wherein the first charging point corresponds to the position of the charging port at the front left side of the vehicle, the second charging point corresponds to the position of the charging port at the rear left side of the vehicle, the third charging point corresponds to the position of the charging port at the rear right side of the vehicle, and the fourth charging point corresponds to the position of the charging port at the front of the vehicle;

[0023] Determining at least one target charging point from at least one charging point according to the first position includes:

[0024] When the first position is located at one side in the width direction of the parking space, the second charging point and the third charging point are determined as target charging points.

[0025] In this way, when the charging equipment is located on one side of the parking space width direction, the charging equipment can reasonably select the target charging point, which can save computing resources on the one hand and improve the rationality of the outlet position on the other hand.

[0026] In some embodiments, before obtaining multiple candidate outlet locations of the charging device, the method further includes:

[0027] Get the charging port heights of different types of vehicles;

[0028] Determine the cable outlet height according to the charging port height of different types of vehicles. The cable outlet height is the distance between the position where the cable extends out of the body and the ground.

[0029] According to the height of the outlet line, multiple candidate outlet line positions of the charging device are determined.

[0030] In this way, by considering the height of the charging port of different types of vehicles, the outlet height of the charging cable can be reasonably determined, thereby optimizing the outlet position to ensure that the needs of different charging points can be met, reducing the required cable length and improving the utilization rate of the cable length.

[0031] In some embodiments, the height of the outlet line is determined according to the height of the charging port of different types of vehicles, including:

[0032] The minimum value among the charging port heights of different types of vehicles is determined as the outlet height.

[0033] In this way, it ensures that the outlet height of the charging cable of the charging device can adapt to the charging needs of different types of vehicles, while avoiding the problem that the charging gun bears a greater cable falling force due to the outlet height being higher than the charging port height when matching different vehicles.

[0034] In some embodiments, the cable parameter further includes a cable length of the charging cable, and after determining the candidate outlet position corresponding to the minimum value of at least one first cable length as the outlet position, the method further includes:

[0035] Determining at least one second cable length between the outlet location and at least one charging point location based on the first location;

[0036] Based on the at least one second cable length, a cable length is determined.

[0037] In this way, the length of the charging cable can be reasonably determined to meet the needs of different charging points without causing waste of the charging cable.

[0038] In some embodiments, determining the cable length based on at least one second cable length includes:

[0039] A maximum value among the at least one second cable length is determined as the cable length.

[0040] In this way, the situation where charging cannot be performed due to insufficient cable length is avoided, and the utilization rate of the cable length is improved.

[0041] In some embodiments, determining at least one second cable length between the outlet position and at least one charging point according to the first position includes:

[0042] Determine a charging path between the outlet position and the fifth charging point according to the first position, the outlet position and the fifth charging point;

[0043] According to the charging path, the charging cable between the outlet position and the fifth charging point is divided to obtain multiple sections of charging cables;

[0044] Determine the length of the second cable between the outlet position and the fifth charging point according to the length of each section of the charging cable;

[0045] The fifth charging point is any one of the at least one charging point.

[0046] In this way, by refining the path and dividing the charging cable segments, the cable length between the outlet position and the charging point is accurately calculated, so that the cable length between the outlet position and the charging point can be accurately determined.

[0047] In some embodiments, the charging cable between the outlet position and the fifth charging point is divided according to the charging path to obtain multiple sections of the charging cable, including:

[0048] Determine the number of bends in the charging path;

[0049] According to the number of bends, the charging cable between the outlet position and the fifth charging point is divided into multiple sections of charging cable.

[0050] In this way, the charging cable segments are divided according to the number of bends, which facilitates the calculation of the length of each charging cable segment and further accurately determines the cable length between the outlet position and the charging point.

[0051] In some embodiments, determining the second cable length between the outlet position and the fifth charging point according to the length of each charging cable segment includes:

[0052] Get the side length of the parking space and the length parameters of the charging gun;

[0053] Determine the length of each charging cable segment based on the side length and length parameters;

[0054] According to the length of each section of the charging cable, the second cable length between the outlet position and the fifth charging point is determined.

[0055] In this way, the length of each section of the charging cable can be calculated according to the side length of the parking space and the length parameters of the charging gun, thereby improving the tolerance of the cable length calculation and ensuring that the length of the charging cable can meet the charging requirements.

[0056] In some embodiments, the length parameter includes a bending radius, and determining the length of the second cable between the outlet position and the fifth charging point according to the length of each section of the charging cable includes:

[0057] Based on the bending radius, determining a bending correction parameter;

[0058] The length of the second cable between the outlet position and the fifth charging point is determined according to the length of each section of the charging cable and the bending correction parameter.

[0059] In this way, the difference between the bend and the straight-line distance can be taken into account and corrected through the bend correction parameter, thereby further improving the accuracy of the cable length calculation.

[0060] In a second aspect, an embodiment of the present application further provides a charging device, including:

[0061] A main body, on which a wire outlet position is arranged;

[0062] A charging gun, used to connect to the charging port of the vehicle so that the charging device can charge the vehicle;

[0063] The charging cable extends out of the main body from the outlet position and is connected to the charging gun;

[0064] Among them, the cable length required between the outlet position and the second charging point is smaller than the cable length required between other positions on the main body and the third charging point. The second charging point is a charging point corresponding to the maximum value of the cable length required between the outlet positions among at least one charging point in the parking space, and the third charging point is a charging point corresponding to the maximum value of the cable length required between at least one charging point and other positions.

[0065] In this way, the outlet position of the charging equipment can be reasonably selected to meet the charging needs of charging points in different locations while reducing the required cable length and improving the utilization rate of the cable length.

[0066] In some embodiments, the distance between the outlet position and the ground is the outlet height;

[0067] The outlet height is the minimum value among the charging port heights of different types of vehicles.

[0068] In this way, by considering the height of the charging ports of different types of vehicles, it is ensured that the height of the charging cable outlet of the charging equipment can adapt to the charging needs of different types of vehicles, while avoiding the problem of the charging gun bearing a greater cable falling force due to the outlet height being higher than the charging port height when matching different vehicles.

[0069] In some embodiments, the cable length of the charging cable is the cable length required between the outlet position and the second charging point.

[0070] In this way, the length of the charging cable can be reasonably determined to meet the needs of different charging points without causing waste of the charging cable, avoiding the situation where charging cannot be performed due to insufficient cable length, and improving the utilization rate of the cable length.

[0071] In a third aspect, an embodiment of the present application further provides a cable parameter determination device, which is applied to a charging device, wherein the charging device includes a body, a charging gun, and a charging cable connecting the body and the charging gun. The cable parameters include an outlet position, which is a position where the charging cable extends out of the body. The device includes:

[0072] An acquisition module, configured to acquire a first position of the charging device relative to the parking space, at least one charging point of the parking space, and a plurality of candidate outlet positions of the charging device;

[0073] A first determination module, configured to determine at least one candidate cable length between each candidate outlet position and at least one charging point according to the first position;

[0074] A second determining module, configured to determine, for each candidate outlet position, a maximum value of at least one candidate cable length as a first cable length corresponding to each candidate outlet position;

[0075] The third determining module is used to determine the candidate outlet position corresponding to the minimum value of the plurality of first cable lengths as the outlet position.

[0076] In this way, by obtaining the first position of the charging device relative to the parking space, at least one charging point of the parking space, and multiple candidate outlet positions of the charging device, the candidate cable length between each candidate outlet position and at least one charging point can be calculated, and the maximum value of these lengths can be used as the first cable length corresponding to each candidate outlet position to ensure that the charging needs of charging points at different positions can be met. Then, the candidate outlet position corresponding to the minimum value of these first cable lengths is determined as the final outlet position, so as to reasonably select the outlet position, reduce the required cable length while meeting the charging needs of charging points at different positions, and improve the utilization rate of the cable length.

[0077] In a fourth aspect, an embodiment of the present application provides an electronic device, comprising: a processor and a memory storing program instructions; when the processor executes the program instructions, the method of the first aspect or the second aspect is implemented.

[0078] In a fifth aspect, an embodiment of the present application provides a machine-readable storage medium having program instructions stored thereon, and the program instructions implement the method of the first aspect or the second aspect when executed by a processor.

[0098] The following detailed description and drawings of the embodiments of the present application are used to illustrate the principles of the present application, but cannot be used to limit the scope of the present application, that is, the present application is not limited to the described embodiments.

[0099] In the description of the present application, it should be noted that, unless otherwise specified, "multiple" means more than two; the terms "upper", "lower", "left", "right", "inside", "outside", etc., indicating the orientation or positional relationship, are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application. In addition, the terms "first", "second", "third", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance. "Vertical" is not strictly vertical, but is within the allowable error range. "Parallel" is not strictly parallel, but is within the allowable error range.

[0100] Reference to "embodiments" in this application means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described in this application may be combined with other embodiments.

[0101] The embodiments of the present application provide a cable parameter determination method, charging device, apparatus, equipment, medium and product to solve the above technical problems. The cable parameter determination method provided by the embodiments of the present application is first introduced below.

[0102] Please refer to Figure 1 The charging device 100 may include a main body 110 , a charging gun 120 , and a charging cable 130 connecting the main body 110 and the charging gun 120 . The cable parameters include a line outlet position, which is a position where the charging cable 130 extends out of the main body 110 .

[0103] like Figure 2 As shown, the method for determining the cable parameters of the charging device may include:

[0104] Step 201 : obtaining a first position of a charging device relative to a parking space, at least one charging point of the parking space, and a plurality of candidate outlet positions of the charging device.

[0105] In step 201, the charging device 100 may be installed on one side of the parking space 200 in the length direction or on one side of the parking space 200 in the width direction. Figure 3 Three common installation positions of the charging device 100 are shown. Taking this as an example, the first position can be position 1, position 2 or position 3.

[0106] It is understandable that the locations of the charging ports of different types of vehicles may be different. For example, the charging port may be located at the left front, left rear, right rear, or front of the vehicle. In this embodiment, the charging device 100 can charge one or more of the above types of vehicles. For example, in order to improve the versatility of the charging device, the charging device 100 can simultaneously meet the charging needs of vehicles with the above four charging port locations.

[0107] like Figure 3 As shown, taking the case where the vehicle is parked in the parking space 200 along the X direction as an example, the charging points of the parking space may include a first charging point C1, a second charging point C2, a third charging point C3 and a fourth charging point C4, wherein the first charging point C1 corresponds to the position of the charging port at the front left side of the vehicle, the second charging point C2 corresponds to the position of the charging port at the rear left side of the vehicle, the third charging point C3 corresponds to the position of the charging port at the rear right side of the vehicle, and the fourth charging point C4 corresponds to the position of the charging port directly in front of the vehicle.

[0108] The multiple candidate outlet positions of the charging device 100 may refer to any position within a specified height range on the body 110. In order to save the length of the charging cable, the multiple candidate outlet positions may be any position within a specified height range on the surface of the body 110 that is relatively closer to the parking space 200.

[0109] Step 202: Determine at least one candidate cable length between each candidate outlet position and at least one charging point according to the first position.

[0110] In step 202, at least one candidate cable length between each candidate outlet position and at least one charging point can be calculated based on the first position. Figures 4 to 6 , which shows the candidate cable lengths between some candidate outlet positions and some charging points at different first positions.

[0111] like Figure 4 As shown, for the charging device 100 at position 1, its candidate outlet positions may include candidate outlet position a and candidate outlet position b. The candidate cable length between the candidate outlet position a and each of the at least one charging position, and the candidate cable length between the candidate outlet position b and each of the at least one charging position may be calculated respectively. For example Figure 4 The candidate cable lengths between the candidate outlet position a and the second charging point C2, the candidate cable lengths between the candidate outlet position b and the second charging point C2, and the candidate cable lengths between the candidate outlet position b and the first charging point C1 are shown.

[0112] like Figure 5 As shown, for the charging device 100 at position 2, its candidate outlet positions may include candidate outlet position c and candidate outlet position d. The candidate cable length between the candidate outlet position c and each of the at least one charging point position, and the candidate cable length between the candidate outlet position d and each of the at least one charging point position may be calculated respectively. For example Figure 5 The candidate cable lengths between the candidate outlet position c and the first charging point C1 and the candidate cable lengths between the candidate outlet position d and the second charging point C2 are shown.

[0113] like Figure 6 As shown, for the charging device 100 at position 3, its candidate outlet position may include a candidate outlet position e. The candidate cable length between the candidate outlet position e and each of the at least one charging point can be calculated respectively. Figure 6 The candidate cable lengths between the candidate outlet position e and the second charging point C2 and the candidate cable lengths between the candidate outlet position e and the third charging point C3 are shown.

[0114] It is understandable that the candidate cable length can be obtained by field measurement or by calculation based on the side length of the parking space, the first position, the candidate appearance position, and the position of the charging point.

[0115] Step 203: for each candidate outlet position, determine the maximum value of at least one candidate cable length as the first cable length corresponding to each candidate outlet position.

[0116] In step 203, for each candidate outlet position, the maximum value of at least one candidate cable length can be determined as the first cable length corresponding to each candidate outlet position. In this way, it can be ensured that the first cable length corresponding to each candidate outlet position can be greater than or equal to the required cable length between it and each charging point, that is, the first cable length corresponding to each candidate outlet position can meet the charging requirements between different charging points.

[0117] Step 204: determine the candidate outlet position corresponding to the minimum value among the plurality of first cable lengths as the outlet position.

[0118] In step 204, multiple first cable lengths may be compared, and the candidate outlet position corresponding to the minimum value may be determined as the outlet position. In this way, the charging requirements of charging points at different locations may be met with a shorter cable length, thereby improving the utilization rate of the cable length.

[0119] In this way, by obtaining the first position of the charging device relative to the parking space, at least one charging point of the parking space, and multiple candidate outlet positions of the charging device, the candidate cable length between each candidate outlet position and at least one charging point can be calculated, and the maximum value of these lengths can be used as the first cable length corresponding to each candidate outlet position to ensure that the charging needs of charging points at different positions can be met. Then, the candidate outlet position corresponding to the minimum value of these first cable lengths is determined as the final outlet position, so as to reasonably select the outlet position, reduce the required cable length while meeting the charging needs of charging points at different positions, and improve the utilization rate of the cable length.

[0120] In some embodiments, when there are multiple charging points, determining at least one candidate cable length between each candidate outlet position and at least one charging point according to the first position includes:

[0121] Determine at least one target charging point from a plurality of charging points according to the first position;

[0122] At least one candidate cable length between each candidate outlet position and at least one target charging point is determined according to the first position.

[0123] In this embodiment, when there are multiple charging points, at least one target charging point can be determined from the multiple charging points according to the first position. Figure 3As shown, for the charging device 100 at position 1 or position 2, the probability of charging at the four charging points is similar, so the first charging point C1, the second charging point C2, the third charging point C3 and the fourth charging point C4 can all be determined as target charging points.

[0124] As for the charging device at position 3, since the vehicle can be parked forward or reversely, if the charging port is in front of the vehicle or in front of the left side, reverse parking can be chosen. At this time, the fourth charging point is closer to the charging device, so only the first charging point needs to be considered. At this time, the positions of the first charging point and the third charging point are close. Therefore, in this case, the second charging point C2 and the third charging point C3 can be directly determined as the target charging points.

[0125] At least one candidate cable length between each candidate outlet position and at least one target charging point may be determined based on the first position. The determination method is the same as above and will not be described in detail here.

[0126] In this way, when there are multiple charging points, we can first determine the more frequently used charging point as the target charging point based on the first position of the charging equipment relative to the parking space to participate in the subsequent candidate cable length calculation, avoiding the calculation of the candidate cable lengths corresponding to all charging points, so as to save computing resources.

[0127] In some embodiments, determining at least one target charging point from a plurality of charging points according to the first position includes:

[0128] Determining a charging path between the first location and each charging point;

[0129] The charging point whose charging path meets the preset conditions is determined as the target charging point.

[0130] In this embodiment, the charging path between the first position and each charging point may be determined, and the target charging point may be determined based on whether the charging path meets the preset conditions.

[0131] For example, a charging point with a charging path less than a preset threshold value may be determined as a target charging point. A charging point with a number of bends on the charging path less than a preset value may also be determined as a target charging point. The length difference of the charging paths between the charging points may also be compared. If the length difference is greater than the preset difference, the charging point with the shorter charging path length may be determined as the target charging point.

[0132] In this way, by determining the charging path between the first position of the charging device and each charging point, the charging points that meet the preset conditions are screened out as target charging points, avoiding the calculation of the candidate cable lengths corresponding to all charging points, so as to achieve the purpose of saving computing power resources.

[0133] In some embodiments, the at least one charging point includes a first charging point, a second charging point, a third charging point, and a fourth charging point, wherein the first charging point corresponds to the position of the charging port at the front left side of the vehicle, the second charging point corresponds to the position of the charging port at the rear left side of the vehicle, the third charging point corresponds to the position of the charging port at the rear right side of the vehicle, and the fourth charging point corresponds to the position of the charging port at the front of the vehicle;

[0134] Determining at least one target charging point from at least one charging point according to the first position includes:

[0135] When the first position is located at one side in the length direction of the parking space, the first charging point, the second charging point, the third charging point and the fourth charging point are determined as target charging points.

[0136] In this embodiment, as mentioned above, the at least one charging point may include a first charging point C1, a second charging point C2, a third charging point C3 and a fourth charging point C4. In the case where the first position is located at one side of the length direction of the parking space, that is, Figure 3 As shown, the charging device 100 is at position 1 or position 2. At this time, the first charging point C1, the second charging point C2, the third charging point C3 and the fourth charging point C4 can be determined as target charging points.

[0137] In this way, by considering the specific location of the charging equipment in the parking space and determining the corresponding target charging point, the outlet position is reasonably selected based on this, so that the length of the charging cable can meet the needs of different charging points, thereby improving the utilization rate of the cable length.

[0138] In some embodiments, the at least one charging point includes a first charging point, a second charging point, a third charging point, and a fourth charging point, wherein the first charging point corresponds to the position of the charging port at the front left side of the vehicle, the second charging point corresponds to the position of the charging port at the rear left side of the vehicle, the third charging point corresponds to the position of the charging port at the rear right side of the vehicle, and the fourth charging point corresponds to the position of the charging port at the front of the vehicle;

[0139] Determining at least one target charging point from at least one charging point according to the first position includes:

[0140] When the first position is located at one side in the width direction of the parking space, the second charging point and the third charging point are determined as target charging points.

[0141] In this embodiment, as mentioned above, the at least one charging point may include a first charging point C1, a second charging point C2, a third charging point C3 and a fourth charging point C4. In the case where the first position is located on one side in the width direction of the parking space, that is, Figure 3 As shown, the charging device 100 is at position 3. At this time, when the vehicle is parked in the parking space 200, forward entry or reverse entry can be considered. In this case, the second charging point C2 and the third charging point C3 can be determined as the target charging point.

[0142] In this way, when the charging equipment is located on one side of the parking space width direction, the charging equipment can reasonably select the target charging point, which can save computing resources on the one hand and improve the rationality of the outlet position on the other hand.

[0143] In some embodiments, Figure 7 As shown, before obtaining multiple candidate outlet positions of the charging device, the method also includes:

[0144] Step 701, obtaining the charging port heights of different types of vehicles;

[0145] Step 702, determining the height of the cable outlet according to the height of the charging port of different types of vehicles, where the height of the cable outlet is the distance between the position where the cable extends out of the body and the ground;

[0146] Step 703: Determine multiple candidate outlet positions of the charging device according to the outlet height.

[0147] In this embodiment, the outlet height of the candidate outlet position can be determined by obtaining the height of the charging port of different types of vehicles.

[0148] For example, the outlet height can be kept consistent with the height of the vehicle's charging port as much as possible. Generally speaking, the height of the charging port of different types of vehicles is generally 0.8~1.2m. The average value of the height of the charging port of different types of vehicles can be obtained as the outlet height. The minimum value can also be used as the outlet height.

[0149] In this way, by considering the height of the charging port of different types of vehicles, the outlet height of the charging cable can be reasonably determined, thereby optimizing the outlet position to ensure that the needs of different charging points can be met, reducing the required cable length and improving the utilization rate of the cable length.

[0150] In some embodiments, the height of the outlet line is determined according to the height of the charging port of different types of vehicles, including:

[0151] The minimum value among the charging port heights of different types of vehicles is determined as the outlet height.

[0152] In this embodiment, in order to prevent the charging gun from bearing a greater cable drop force when matching different types of vehicles, the minimum value of the charging port heights of different types of vehicles can be determined as the outlet height. For example, the outlet height can be 0.8m.

[0153] In this way, it ensures that the outlet height of the charging cable of the charging device can adapt to the charging needs of different types of vehicles, while avoiding the problem that the charging gun bears a greater cable falling force due to the outlet height being higher than the charging port height when matching different vehicles.

[0154] In some embodiments, Figure 8 As shown, the cable parameter also includes the cable length of the charging cable. After determining the candidate outlet position corresponding to the minimum value of at least one first cable length as the outlet position, the method further includes:

[0155] Step 801, determining at least one second cable length between an outlet position and at least one charging point according to the first position;

[0156] Step 802: Determine a cable length based on at least one second cable length.

[0157] In this embodiment, after determining the outlet position, at least one second cable length between the outlet position and at least one charging point can be determined. The at least one second cable length can be recalculated using the candidate cable length determination method mentioned above. It is also possible to directly match the at least one candidate cable length between the outlet position and at least one charging point based on the at least one candidate cable length between each candidate outlet position and at least one charging point obtained above, as the at least one second cable length.

[0158] The cable length may be determined based on at least one second cable length. For example, a preset length may be added to the longest second cable length to obtain a final cable length of the charging cable.

[0159] In this way, the length of the charging cable can be reasonably determined to meet the needs of different charging points without causing waste of the charging cable.

[0160] In some embodiments, determining the cable length based on at least one second cable length includes:

[0161] A maximum value among the at least one second cable length is determined as the cable length.

[0162] In this embodiment, the maximum value of the at least one second cable length may be directly determined as the cable length, so that the cable length is just enough to charge the farthest charging point.

[0163] In this way, the situation where charging cannot be performed due to insufficient cable length is avoided, and the utilization rate of the cable length is improved.

[0164] In some embodiments, determining at least one second cable length between the outlet position and at least one charging point according to the first position includes:

[0165] Determine a charging path between the outlet position and the fifth charging point according to the first position, the outlet position and the fifth charging point;

[0166] According to the charging path, the charging cable between the outlet position and the fifth charging point is divided to obtain multiple sections of charging cables;

[0167] Determine the length of the second cable between the outlet position and the fifth charging point according to the length of each section of the charging cable;

[0168] The fifth charging point is any one of the at least one charging point.

[0169] In this embodiment, for any charging point, i.e., the fifth charging point, the second cable length between the outlet position and the fifth charging point is calculated. The charging path between the outlet position and the fifth charging point can be determined based on the first position, the outlet position, and the fifth charging point. According to the charging path, the charging cable between the outlet position and the fifth charging point is divided to obtain multiple charging cables, and then the length of each charging cable is calculated respectively, and finally the second cable length between the outlet position and the fifth charging point is obtained.

[0170] It can be understood that the above-mentioned determination of at least one candidate cable length between each candidate outlet position and at least one charging point according to the first position can be calculated using the same method.

[0171] See also Figures 9 to 12 The charging cable can be divided according to the charging path to obtain multiple cable segments. Different first positions, different outlet positions or different charging points have different corresponding charging paths, and the number of cable segments obtained by division is also different.

[0172] In this way, by refining the path and dividing the charging cable segments, the cable length between the outlet position and the charging point is accurately calculated, so that the cable length between the outlet position and the charging point can be accurately determined.

[0173] In some embodiments, the charging cable between the outlet position and the fifth charging point is divided according to the charging path to obtain multiple sections of the charging cable, including:

[0174] Determine the number of bends in the charging path;

[0175] According to the number of bends, the charging cable between the outlet position and the fifth charging point is divided into multiple sections of charging cable.

[0176] In this embodiment, the number of bends in the charging path may be counted. In actual operation, the bends at the outlet position of the charging cable may not be included when counting the number of bends.

[0177] The charging cable between the outlet position and the fifth charging point can be divided according to the number of bends to obtain multiple segments of the charging cable. For example, the bend can be used as a dividing node for different cable segments. In other words, the number of charging cable segments can be equal to the number of bends plus one.

[0178] like Fig. 9 As shown, the charging cable between the outlet position and the fifth charging point may include a first section a901, a second section a902, a third section a903, a fourth section a904 and a fifth section a905.

[0179] like Fig.10 As shown, the charging cable between the outlet position and the fifth charging point may include a first section b1001, a second section b1002, a third section b1003 and a fourth section b1004.

[0180] like Fig.11 As shown, the charging cable between the outlet position and the fifth charging point may include a first section c1101, a second section c1102, a third section c1103, a fourth section c1104 and a fifth section c1105.

[0181] like Fig.12 As shown, the charging cable between the outlet position and the fifth charging point may include a first section d1201, a second section d1202, a third section d1203 and a fourth section d1204.

[0182] In this way, the charging cable segments are divided according to the number of bends, which facilitates the calculation of the length of each charging cable segment and further accurately determines the cable length between the outlet position and the charging point.

[0183] In some embodiments, determining the second cable length between the outlet position and the fifth charging point according to the length of each charging cable segment includes:

[0184] Get the side length of the parking space and the length parameters of the charging gun;

[0185] Determine the length of each charging cable segment based on the side length and length parameters;

[0186] According to the length of each section of the charging cable, the second cable length between the outlet position and the fifth charging point is determined.

[0187] In this embodiment, the side length of the parking space and the length parameters of the charging gun can be obtained, wherein the side length of the parking space may include the length W of the parking space and the width D of the parking space. Figure 1 As shown, the length parameters of the charging gun may include the charging gun length L0 and the bending radius R.

[0188] The length of each section of the charging cable can be determined according to the side length and the length parameter, and the second cable length between the outlet position and the fifth charging point can be determined according to the length of each section of the charging cable.

[0189] For example, Fig. 9 As shown, taking the fifth charging point as the first charging point C1 as an example. The length of the first section a901 can be d1, wherein d1 is the distance between the surface of the body 110 of the charging device 100 close to the parking space 200 and the edge of the parking space 200 close to the charging device 100. The length of the second section a902 can be W-d2-d3, wherein W is the length of the parking space 200, d2 is the distance between the outlet position and the tail of the parking space 200, and d3 is the horizontal offset of the charging cable 130 at the outlet position. The length of the third section a903 can be D+L0+R, wherein D is the width of the parking space 200, and L0+R is the correction of the charging gun length L0 and the bending radius R of the added charging gun 120. The length of the fourth section a904 can be d4, where d4 is the distance between the first charging point C1 and the front end of the parking space 200. It can be understood that the position of the first charging point C1 corresponds to the position of the charging port when the vehicle parking position is flush with the rear of the parking space 200. The length of the fifth section can be L0+R, where L0 is the length of the charging gun and R is the bending radius. Therefore, the length of the second cable between the outlet position and the fifth charging point can be the length of the first section a901 + the length of the second section a902 + the length of the third section a903 + the length of the fourth section a904 + the length of the fifth section a905 = d1+(W-d2-d3)+D+d4+2*(L0+R).

[0190] like Fig.10 As shown, the fifth charging point is taken as the first charging point C1 as an example. The length of the second segment b1002, the length of the third segment b1003 and the length of the fourth segment b1004 are respectively Fig. 9The length of the third section a903, the length of the fourth section a904 and the length of the fifth section a905 are the same, and are not described here. The length of the first section b1001 can be √((W-d2)²+(d1+d3)²), where d1 is the distance between the surface of the body 110 of the charging device 100 close to the parking space 200 and the edge of the parking space 200 close to the charging device 100, W is the length of the parking space 200, d2 is the distance between the outlet position and the tail of the parking space 200, and d3 is the horizontal offset of the charging cable 130 at the outlet position. Therefore, the length of the second cable between the outlet position and the fifth charging point can be the length of the first section b1001 + the length of the second section b1002 + the length of the third section b1003 + the length of the fourth section b1004 = √((W-d2)²+(d1+d3)²)+D+d4+2*(L0+R).

[0191] like Fig.11 As shown, taking the fifth charging point as the second charging point C2 as an example. The length of the first section c1101 can be d1+d3, wherein d1 is the distance between the surface of the body 110 of the charging device 100 close to the parking space 200 and the edge of the parking space 200 close to the charging device 100, and d3 is the horizontal offset of the charging cable 130 at the outlet position. The length of the second section c1102 can be d2+d3, wherein d2 is the distance between the outlet position and the tail of the parking space 200, and d3 is the horizontal offset of the charging cable 130 at the outlet position. The length of the third section c1103 can be D+L0+R, wherein D is the width of the parking space 200, and L0+R is the correction of the charging gun length L0 and the bending radius R of the added charging gun 120. The length of the fourth section c1104 can be d5, where d5 is the distance between the second charging point C2 and the rear of the parking space 200. It can be understood that the position of the second charging point C2 corresponds to the position of the charging port when the vehicle parking position is flush with the front end of the parking space 200. The length of the fifth section can be L0+R, where L0 is the length of the charging gun and R is the bending radius. Therefore, the length of the second cable between the outlet position and the fifth charging point can be the length of the first section c1101 + the length of the second section c1102 + the length of the third section c1103 + the length of the fourth section c1104 + the length of the fifth section c1105 = d1+d2+2*d3++D+d5+2*(L0+R).

[0192] like Fig.12 As shown, the fifth charging point is the third charging point C3, and the third charging point C3 is symmetrical to the second charging point C2. Among them, the length of the third section d1203 and the length of the fourth section d1204 are respectively Fig.11The length of the fourth section c1104 is the same as the length of the fifth section c1105, which will not be described in detail here. The length of the first section d1201 can be d1, where d1 is the distance between the surface of the body 110 of the charging device 100 close to the parking space 200 and the edge of the parking space 200 close to the charging device 100, and the length of the second section d1202 can be 1 / 2*D+L0+R, where D is the width of the parking space 200, and L0+R is the correction of the added charging gun length L0 and the bending radius R of the charging gun 120. Therefore, the length of the second cable between the outlet position and the fifth charging point can be the length of the first section d1201 + the length of the second section d1202 + the length of the third section d1203 + the length of the fourth section d1204 = d1+1 / 2*D+d5+2*(L0+R).

[0193] In this way, the length of each section of the charging cable can be calculated according to the side length of the parking space and the length parameters of the charging gun, thereby improving the tolerance of the cable length calculation and ensuring that the length of the charging cable can meet the charging requirements.

[0194] In some embodiments, the length parameter includes a bending radius, and determining the length of the second cable between the outlet position and the fifth charging point according to the length of each section of the charging cable includes:

[0195] Based on the bending radius, determining a bending correction parameter;

[0196] The length of the second cable between the outlet position and the fifth charging point is determined according to the length of each section of the charging cable and the bending correction parameter.

[0197] In this embodiment, it can be understood that Fig.13 As shown, when the charging cable is bent, there is a length difference between the bent path 1301 and the straight path 1302. In order to more accurately calculate the cable length, the length difference needs to be corrected. Based on this, the bending correction parameter can be determined based on the bending radius. Among them, the bending correction parameter can be 1 / 4*π*R–2*R / √2≈0.08*R.

[0198] The second cable length between the outlet position and the fifth charging point can be determined according to the length of each charging cable segment and the bend correction parameter. It is understandable that the cable length needs to be corrected according to the bend correction coefficient for each bend, and the number of bends needs to take into account the number of all bends on the charging path to ensure the accuracy of the cable length.

[0199] Based on this, Fig. 9 The length of the second cable between the middle outlet position and the fifth charging point may be d1+(W-d2-d3)+D+d4+2*(L0+R)+4*0.08*R. Fig.10The length of the second cable between the middle outlet position and the fifth charging point can be √((W-d2)²+(d1+d3)²)+D+d4+2*(L0+R)+3*0.08*R. Fig.11 The length of the second cable between the middle outlet position and the fifth charging point may be d1+d2+2*d3++D+d5+2*(L0+R)+5*0.08*R. Fig.12 The length of the second cable between the middle outlet position and the fifth charging point may be d1+1 / 2*D+d5+2*(L0+R)+3*0.08*R.

[0200] In this way, the difference between the bend and the straight-line distance can be taken into account and corrected through the bend correction parameter, thereby further improving the accuracy of the cable length calculation.

[0201] Based on the cable parameter determination method provided in the above embodiment, the present application also provides an embodiment of a cable parameter determination device.

[0202] For ease of explanation, only the parts related to the embodiments of the present application are shown.

[0203] It can be understood that the charging device includes a main body, a charging gun and a charging cable connecting the main body and the charging gun, and the cable parameters include a line outlet position, which is a position where the charging cable extends out of the main body.

[0204] Reference Fig.14 , the cable parameter determination device 1400 may include:

[0205] An acquisition module 1401 is used to acquire a first position of a charging device relative to a parking space, at least one charging point of the parking space, and a plurality of candidate outlet positions of the charging device;

[0206] A first determination module 1402 is used to determine at least one candidate cable length between each candidate outlet position and at least one charging point according to the first position;

[0207] A second determining module 1403 is used to determine, for each candidate outlet position, a maximum value of at least one candidate cable length as a first cable length corresponding to each candidate outlet position;

[0208] The third determining module 1404 is configured to determine the candidate outlet position corresponding to the minimum value among the plurality of first cable lengths as the outlet position.

[0209] In this way, by obtaining the first position of the charging device relative to the parking space, at least one charging point of the parking space, and multiple candidate outlet positions of the charging device, the candidate cable length between each candidate outlet position and at least one charging point can be calculated, and the maximum value of these lengths can be used as the first cable length corresponding to each candidate outlet position to ensure that the charging needs of charging points at different positions can be met. Then, the candidate outlet position corresponding to the minimum value of these first cable lengths is determined as the final outlet position, so as to reasonably select the outlet position, reduce the required cable length while meeting the charging needs of charging points at different positions, and improve the utilization rate of the cable length.

[0210] In some embodiments, when there are multiple charging points, the first determining module 1402 may also be used to:

[0211] Determine at least one target charging point from a plurality of charging points according to the first position;

[0212] At least one candidate cable length between each candidate outlet position and at least one target charging point is determined according to the first position.

[0213] In this way, when there are multiple charging points, we can first determine the more frequently used charging point as the target charging point based on the first position of the charging equipment relative to the parking space to participate in the subsequent candidate cable length calculation, avoiding the calculation of the candidate cable lengths corresponding to all charging points, so as to save computing resources.

[0214] In some embodiments, the first determining module 1402 may also be used to:

[0215] Determining a charging path between the first location and each charging point;

[0216] The charging point whose charging path meets the preset conditions is determined as the target charging point.

[0217] In this way, by determining the charging path between the first position of the charging device and each charging point, the charging points that meet the preset conditions are screened out as target charging points, avoiding the calculation of the candidate cable lengths corresponding to all charging points, so as to achieve the purpose of saving computing power resources.

[0218] In some embodiments, the at least one charging point includes a first charging point, a second charging point, a third charging point, and a fourth charging point, wherein the first charging point corresponds to the position of the charging port at the front left side of the vehicle, the second charging point corresponds to the position of the charging port at the rear left side of the vehicle, the third charging point corresponds to the position of the charging port at the rear right side of the vehicle, and the fourth charging point corresponds to the position of the charging port at the front of the vehicle;

[0219] The first determining module 1402 may also be used to:

[0220] When the first position is located at one side in the length direction of the parking space, the first charging point, the second charging point, the third charging point and the fourth charging point are determined as target charging points.

[0221] In this way, by considering the specific location of the charging equipment in the parking space and determining the corresponding target charging point, the outlet position is reasonably selected based on this, so that the length of the charging cable can meet the needs of different charging points, thereby improving the utilization rate of the cable length.

[0222] In some embodiments, the at least one charging point includes a first charging point, a second charging point, a third charging point, and a fourth charging point, wherein the first charging point corresponds to the position of the charging port at the front left side of the vehicle, the second charging point corresponds to the position of the charging port at the rear left side of the vehicle, the third charging point corresponds to the position of the charging port at the rear right side of the vehicle, and the fourth charging point corresponds to the position of the charging port at the front of the vehicle;

[0223] The first determining module 1402 may also be used to:

[0224] When the first position is located at one side in the width direction of the parking space, the second charging point and the third charging point are determined as target charging points.

[0225] In this way, when the charging equipment is located on one side of the parking space width direction, the charging equipment can reasonably select the target charging point, which can save computing resources on the one hand and improve the rationality of the outlet position on the other hand.

[0226] In some embodiments, the acquisition module 1401 may also be used to: acquire the height of the charging port of different types of vehicles;

[0227] The cable parameter determination device 1400 of the charging device may further include:

[0228] A fourth determination module is used to determine the height of the cable outlet according to the height of the charging port of different types of vehicles, where the height of the cable outlet is the distance between the position where the cable extends out of the body and the ground;

[0229] The fifth determination module is used to determine a plurality of candidate outlet positions of the charging device according to the outlet height.

[0230] In this way, by considering the height of the charging port of different types of vehicles, the outlet height of the charging cable can be reasonably determined, thereby optimizing the outlet position to ensure that the needs of different charging points can be met, reducing the required cable length and improving the utilization rate of the cable length.

[0231] In some embodiments, the fourth determining module may also be used to:

[0232] The minimum value among the charging port heights of different types of vehicles is determined as the outlet height.

[0233] In this way, it ensures that the outlet height of the charging cable of the charging device can adapt to the charging needs of different types of vehicles, while avoiding the problem that the charging gun bears a greater cable falling force due to the outlet height being higher than the charging port height when matching different vehicles.

[0234] In some embodiments, the cable parameter further includes the cable length of the charging cable, and the cable parameter determination device 1400 of the charging device may further include:

[0235] a sixth determination module, configured to determine at least one second cable length between the outlet position and at least one charging point according to the first position;

[0236] The seventh determination module is used to determine the cable length according to at least one second cable length.

[0237] In this way, the length of the charging cable can be reasonably determined to meet the needs of different charging points without causing waste of the charging cable.

[0238] In some embodiments, the seventh determination module may also be used to:

[0239] A maximum value among the at least one second cable length is determined as the cable length.

[0240] In this way, the situation where charging cannot be performed due to insufficient cable length is avoided, and the utilization rate of the cable length is improved.

[0241] In some embodiments, the sixth determination module may also be used to:

[0242] Determine a charging path between the outlet position and the fifth charging point according to the first position, the outlet position and the fifth charging point;

[0243] According to the charging path, the charging cable between the outlet position and the fifth charging point is divided to obtain multiple sections of charging cables;

[0244] Determine the length of the second cable between the outlet position and the fifth charging point according to the length of each section of the charging cable;

[0245] The fifth charging point is any one of the at least one charging point.

[0246] In this way, by refining the path and dividing the charging cable segments, the cable length between the outlet position and the charging point is accurately calculated, so that the cable length between the outlet position and the charging point can be accurately determined.

[0247] In some embodiments, the sixth determination module may also be used to:

[0248] Determine the number of bends in the charging path;

[0249] According to the number of bends, the charging cable between the outlet position and the fifth charging point is divided into multiple sections of charging cable.

[0250] In this way, the charging cable segments are divided according to the number of bends, which facilitates the calculation of the length of each charging cable segment and further accurately determines the cable length between the outlet position and the charging point.

[0251] In some embodiments, the sixth determination module may also be used to:

[0252] Get the side length of the parking space and the length parameters of the charging gun;

[0253] Determine the length of each charging cable segment based on the side length and length parameters;

[0254] According to the length of each section of the charging cable, the second cable length between the outlet position and the fifth charging point is determined.

[0255] In this way, the length of each section of the charging cable can be calculated according to the side length of the parking space and the length parameters of the charging gun, thereby improving the tolerance of the cable length calculation and ensuring that the length of the charging cable can meet the charging requirements.

[0256] In some embodiments, the length parameter includes a bending radius. The sixth determination module may also be used to:

[0257] Based on the bending radius, determining a bending correction parameter;

[0258] The length of the second cable between the outlet position and the fifth charging point is determined according to the length of each section of the charging cable and the bending correction parameter.

[0259] In this way, the difference between the bend and the straight-line distance can be taken into account and corrected through the bend correction parameter, thereby further improving the accuracy of the cable length calculation.

[0265] The charging cable 130 extends out of the body 110 from the outlet position and is connected to the charging gun 120;

[0266] Among them, the cable length required between the outlet position and the second charging point is smaller than the cable length required between other positions on the main body and the third charging point. The second charging point is a charging point corresponding to the maximum value of the cable length required between the outlet positions among at least one charging point in the parking space, and the third charging point is a charging point corresponding to the maximum value of the cable length required between at least one charging point and other positions.

[0267] In this way, the outlet position of the charging equipment can be reasonably selected to meet the charging needs of charging points in different locations while reducing the required cable length and improving the utilization rate of the cable length.

[0268] In some embodiments, the distance between the outlet position and the ground is the outlet height;

[0269] The outlet height is the minimum value among the charging port heights of different types of vehicles.

[0270] In this way, by considering the height of the charging ports of different types of vehicles, it is ensured that the outlet height of the charging cable 130 of the charging device can adapt to the charging needs of different types of vehicles, while avoiding the problem of the charging gun 120 bearing a greater cable falling force due to the outlet height being higher than the charging port height when matching different vehicles.

[0271] In some embodiments, the cable length of the charging cable 130 is the cable length required between the outlet position and the second charging point.

[0272] In this way, the length of the charging cable 130 can be reasonably determined to meet the needs of different charging points without causing waste of the charging cable, avoiding the situation where charging cannot be performed due to insufficient cable length, and improving the utilization rate of the cable length.
