Abstract
Description
Technical Field
[0001] The present invention relates generally to charging cables and, in particular, to a coiled charging cable for an electric vehicle. Background Art
[0002] Electric vehicles are usually charged at a charging station with the aid of a charging cable. In addition to charging cables that are permanently connected to the charging station, there are also charging cables that are carried by the user. An example of the latter is the so-called Mode 3 charging cable. For the charging process, such charging cables are usually connectable at one end to a charging station / charging point / wallbox, and at their other end to the electric vehicle. Depending on their shape, charging cables for electric vehicles can be divided into smooth charging cables and spiral / helical charging cables (also often called spiral charging cables), which are mostly referred to as spiral charging cables in this article.
[0003] Smooth charging cables have the advantage that their entire length can be used without any problems. On the other hand, they are less manageable and may take longer to store, roll up, and unroll.
[0004] Because spiral charging cables cannot be fully extended, it is impossible to use their entire length. However, they do not have to be unfolded in advance for each charging process. Although spiral charging cables are slightly shorter than smooth charging cables when in use due to the spiralization, their spiral shape means that they still take up a relatively large amount of space when stored. This is particularly because, when spiral charging cables are placed in the car with both plugs oriented in one direction, they form a "bulge". Therefore, a very large amount of space is required. In addition, due to their restoring forces, they strive to return to their original shape (accordion effect and memory effect) and can therefore hardly or not be stored in a compact manner. If a spiral charging cable is connected to a charging station / charging point, it usually does not lie partially on the ground, but droops, thereby forming a kind of bulge. In the context of public charging, this bulge pattern / drooping in the bulge constitutes a tripping hazard and thus poses an accident risk. If the charging cable is allowed to droop freely for a long time, the restoring force (memory effect) will be reduced or even completely lost. Furthermore, if coiled charging cables are not carefully stored, they may become tangled and thus become correspondingly bulky and difficult to manage.
[0005] The prior art discloses spiral charging cables that are wound in one winding direction. To produce these cables, a spiral block of charging cable is wound in one direction onto a spiraling mandrel. The resulting shape is then heated ("baked") and further processed to form the finished spiral charging cable. Also known are spiral charging cables that are wound in one winding direction and widen, that is, the spiral is wound wider and wider.
[0006] However, the spiral charging cables known in the prior art still have the problem that they cannot be stored in a way that saves as much space as possible. In addition, the spiral charging cables sag in a convex manner during use. and the problem of bulge formation posing an accident risk is likely to persist.
[0007] Therefore, it is necessary to provide a spiral charging cable for electric vehicles with improved storability. In particular, when the spiral charging cable is not in use, it can be stored in a manner that saves as much space as possible. Summary of the Invention
[0008] According to a first aspect of the present invention, a spiral charging cable for an electric vehicle is provided. The charging cable has at least one first portion. In the at least one first portion, the charging cable has at least one turn. In the at least one first portion, the longitudinal axis of the charging cable extends in a first direction. The charging cable also has at least one second portion. In the at least one second portion, the charging cable has at least one turn. In the at least one second portion, the longitudinal axis of the charging cable extends in a second direction. The charging cable also has at least one reverse portion. The at least one reverse portion connects the at least one first portion and the at least one second portion together. The at least one reverse portion extends in a reverse direction. The reverse direction is different from the first direction and / or the second direction.
[0009] By forming a charging cable having a first portion, a second portion and a reverse portion, wherein the direction of the reverse portion (reverse direction) is different from the first and / or second direction, a more compact structure and / or storage and / or better storage performance can be achieved than in the case of conventional spiral charging cables.
[0010] Technically, the longitudinal axis generally refers to the axis of an object corresponding to the direction of its greatest extension. Therefore, the longitudinal axis of the charging cable can be understood as the axis along the longitudinal extent of the charging cable. The at least one turn in the first portion and the at least one turn in the second portion can extend / form around the longitudinal axis, or, in other words, the longitudinal axis can extend through at least one turn in the first portion and at least one turn in the direction of the second portion. Because the reverse direction is different from the first direction and / or the second direction, the longitudinal axis of the charging cable is not constant over the entire length of the charging cable, but rather varies as the longitudinal extent of the corresponding portion (first portion, second portion, reverse portion) of the charging cable changes.
[0011] The charging cable may include a spiral having a total spiral length. The at least one first portion may form a first spiral portion of the spiral. In other words, the at least one turn in the at least one first portion may form a portion of the spiral as the first spiral portion. The at least one second portion may form a second spiral portion of the spiral. In other words, the at least one turn in the at least one second portion may form a portion of the spiral as the second spiral portion. The first spiral portion and the second spiral portion may together form the spiral having a total spiral length.
[0012] In at least one first section, the charging cable can be wound along a first winding direction. In other words, the at least one turn in the at least one first section can be wound along the first winding direction. In at least one second section, the charging cable can be wound along a second winding direction. In other words, the at least one turn in the at least one second section can be wound along the second winding direction. Thus, the first helical section can be wound along the first winding direction, and the second helical section can be wound along the second winding direction.
[0013] According to a first exemplary embodiment, the first and second winding directions may correspond. In this case, the first helical portion and the second helical portion may be wound along the same winding direction. According to another exemplary embodiment, the first and second winding directions may be different. In this case, the first helical portion and the second helical portion may be wound along different winding directions. For example, the first and second winding directions may be opposite. In this case, the first helical portion and the second helical portion may be wound along opposite winding directions.
[0014] The first direction in which the longitudinal axis of the charging cable extends in the first portion and the second direction in which the longitudinal axis of the charging cable extends in the second portion may be parallel to / correspond to each other. When the first and second directions are arranged in parallel, the first direction may be perpendicular to the longitudinal axis of the charging cable and offset from the second direction, or vice versa. In other words, the first and second spiral portions may be arranged parallel to each other and extend in the same direction. Alternatively, the first and second directions may be different from each other. For example, the first and second directions may be non-parallel to each other, for example, inclined to each other.
[0015] The at least one reversing region extends in a reverse direction. The reverse direction is different from the first direction and / or the second direction. For example, the reverse direction may be perpendicular to the first direction and / or the second direction. In other words, the reversing region may extend in a different direction, for example, perpendicular to the first spiral portion and / or the second spiral portion. In this way, a particularly compact structure and storage can be achieved compared to conventional spiral charging cables.
[0016] The length of the at least one first portion may correspond to the length of the at least one second portion. For example, the at least one first portion and the at least one second portion may each be formed by half, a quarter or another fraction of the spiral length of the charging cable. If the length of the first portion corresponds to the length of the second portion, a symmetrical shape of the charging cable is possible. In this way, a particularly more compact structure and storage can be achieved compared to conventional spiral charging cables. By forming two, four or more than four first and second portions, the length of the first portion and the length of the second portion can be shortened while the total length of the charging cable remains unchanged. In this way, a more compact structure and storage in the longitudinal direction can be achieved compared to conventional spiral charging cables.
[0017] The at least one reverse portion may have or be in the form of a straight portion. The at least one reverse portion connects the at least one first portion, which is a first portion of the charging cable's spiral, and the at least one second portion, which is a second portion of the charging cable's spiral. The charging cable may be unwound / have no turns in the straight portion of the reverse portion. In other words, the straight portion connects the first and second spiral portions. The straight portion allows the first and second portions to be connected in a compact manner.
[0018] According to the specific configuration, a plurality of first portions may be formed, a plurality of second portions may be formed, and a plurality of reverse portions may be formed. In other words, the spiral charging cable may have a plurality of first portions, a plurality of second portions, and a plurality of reverse portions.
[0019] The at least one first portion may be in the form of a plurality of first portions. The at least one second portion may be in the form of a plurality of second portions. The number of the plurality of first portions may correspond to the number of the plurality of second portions. However, the number of the first portions and the number of the second portions may also be different. Depending on the number of the first and second portions, the proportional lengths of the first and second portions may be adapted to the total length of the charging cable. According to one example, the number of the at least one first portion and the number of the at least one second portion may each be one. In this case, in each case, half of the coil of the charging cable may form the first portion and the second portion. According to another example, the number of the at least one first portion and the number of the at least one second portion may each be two. In this case, in each case, a quarter of the coil of the charging cable may form two first portions and two second portions. Those skilled in the art will be able to conceive of other examples and implement them accordingly.
[0020] Depending on the number of first parts and the number of second parts, a corresponding number of reverse parts can be formed. For example, in each case, one reverse part can be provided for connecting one first part and one second part together. Thus, the number of reverse parts can be determined by the larger of the number of first parts and the number of second parts. For example, if two first parts and one second part are provided, a total of two reverse parts can be provided.
[0021] The first portions of the plurality of first portions and the second portions of the plurality of second portions can be arranged in an alternating manner. In other words, the first portion and the reverse portion can be followed by the second portion, which can in turn be followed by the reverse portion and the first portion, etc. In other words, in each case, the reverse portion of the at least one reverse portion can be formed between a first portion of the plurality of first portions and a second portion of the plurality of second portions. Accordingly, in each case, the reverse portion of the at least one reverse portion, in particular the reverse portion of the plurality of reverse portions, can be formed between a second portion of the plurality of second portions and a first portion of the plurality of first portions.
[0022] According to a first conceivable variant, the inverting directions of the plurality of inverting sections between a first portion of the plurality of first portions and a second portion of the plurality of second portions can in each case be parallel to one another. According to a second variant, which can also be combined with the first variant with regard to some inverting sections, the inverting directions of the plurality of inverting sections between a first portion of the plurality of first portions and a second portion of the plurality of second portions can in each case be oriented at an angle, in particular at a 90° angle, to one another.
[0023] According to a second aspect, a charging station having a charging cable according to the first aspect is provided.
[0024] Although some of the above aspects have been described with respect to the charging cable according to the first aspect, these aspects may also be implemented in a corresponding manner in the charging station according to the second aspect, and vice versa. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] Figure 2 : A second exemplary embodiment of a spiral charging cable. DETAILED DESCRIPTION
[0028] In the following, specific details are provided to provide a complete understanding of the present invention, but are not intended to be limiting. However, it will be clear to those skilled in the art that the present invention may be used in other exemplary embodiments that may differ from the details presented below. In addition, the drawings are only for the purpose of illustrating the exemplary embodiments. They are not drawn to scale and are intended to reflect the overall concept of the present invention by way of example only. For example, the features included in the drawings should not be considered essential elements.
[0029] Figure 1 A first exemplary embodiment of a spiral charging cable 10 for an electric vehicle is shown. The charging cable 10 has at least one first portion 20. In the at least one first portion 20, the charging cable 10 has at least one turn. In the at least one first portion 20, the longitudinal axis of the charging cable 10 extends in a first direction. Figure 1 In the description of FIG, the first direction extends in the horizontal direction. The charging cable 10 has at least one second portion 30. In at least one second portion 30, the charging cable 10 has at least one turn. In at least one second portion 30, the longitudinal axis of the charging cable 10 extends in the second direction. Figure 1 In the description, the second direction extends in the horizontal direction. The charging cable 10 has at least one reverse portion 40. The at least one reverse portion 40 connects at least one first portion 20 and at least one second portion 30 together. The at least one reverse portion 40 extends in the reverse direction. The reverse direction is different from the first direction and / or the second direction. Figure 1 In the example shown, the reverse direction is different from both the first direction and the second direction. Figure 1 In the description, the first reverse direction is perpendicular to the first direction and the second direction, that is, extends in the vertical direction.
[0030] Reference Figure 1 , a first exemplary embodiment of the charging cable 10 will be described more precisely as follows. It should be noted that Figure 1 In the exemplary embodiment of the present invention, only one first portion 20, one second portion 30 and one reverse portion 40 are shown by way of example. However, in a variant, more than one first portion 20, more than one second portion 30 and / or more than one reverse portion 40 may be provided in the charging cable 10.
[0031] In the first lead-out portion 50, the charging cable 10 extends straight / unwound (without turns) in its longitudinal direction. The charging cable merges from the first lead-out portion 50 into the first portion 20. In the first portion 20, the charging cable 10 is wound helically and forms a helical shape as it originally was. The first portion 20 can also be referred to as a first helical portion or a first winding portion 20. The helix in the first helical portion 20 is wound along a first winding direction. When viewed from the first lead-out portion 50 in the direction toward the first helical portion 20, the first portion 20 is wound in a first winding direction. Figure 1 Generally, the first lead-out portion 50 can be implemented in different ways, such as axially or tangentially.
[0032] exist Figure 1 In the exemplary embodiment of the present invention, the reverse portion 40 in the form of a straight line extends perpendicularly to the first spiral portion 20 at one end of the first spiral portion 20. One end of the reverse portion 40 is connected to the first portion 20. In the reverse portion 40, the charging cable 10 is not wound, that is, there are no turns in the charging cable 10.
[0033] Again perpendicular to the reverse portion 40 and parallel to the first spiral portion 20, a second portion 30 is formed (starting from the other end of the reverse portion 40), in which the charging cable 10 is spirally wound and forms a spiral shape as it originally did. The second portion 30 may also be referred to as a second spiral portion or a second winding portion 30. After the second winding portion 30, the second lead-out portion 60 of the charging cable 10 extends straight / unwound (without turns) in the longitudinal direction of the charging cable 10. Generally, the second lead-out portion 60 can be realized in different ways, for example axially or tangentially. The spiral in the second spiral portion 30 is wound along a second winding direction, as viewed from the second lead-out portion 60 in a direction towards the second spiral portion 30. Figure 1 That is, in the first exemplary embodiment, the first winding direction of the helix in the first helical portion 20 corresponds to the second winding direction of the helix in the second helical portion 30, ie, the counterclockwise direction.
[0034] If the charging cable 10 is viewed at the reverse portion 40, that is, at Figure 1 In the configuration shown in the example, when viewed from the right side, the first spiral portion 20 is located on the right side of the reverse portion 40, and the second spiral portion is located on the left side of the reverse portion 40. Figure 1 When viewing the charging cable 10 at the reverse portion 40, the first spiral portion 20 and the second spiral portion 30 are located on different sides of the reverse portion in the horizontal direction. In addition, the first spiral portion 20 and the second spiral portion 30 are located at different positions in the vertical direction.
[0035] Therefore, in summary, it can be said that in the first spiral portion 20, the charging cable is wound, for example, counterclockwise to show a first winding direction. In the second spiral portion 30, the charging cable is also wound counterclockwise to show a second winding direction. Figure 1 In the first exemplary embodiment, the winding direction of the spirals in at least one first portion 20 and at least one second portion 30 is, for example, the same, that is, the first and second winding directions correspond. In other words, in the first portion 20 and the second portion 30, the spirals formed by winding the charging cable 10 have the same winding direction.
[0036] In addition, Figure 1 In the first exemplary embodiment, the first portion 20 and the second portion 30 extend parallel to each other but are offset in the vertical direction. Figure 1 In the first exemplary embodiment, the length of the first portion 20 corresponds to the length of the second portion 30. Figure 1 In the exemplary embodiment of the present invention, the reverse portion 40 connecting the first portion 20 and the second portion 30 together is in the form of a straight portion. In the straight portion, the charging cable is not wound / has no turns. Figure 1 In the exemplary embodiment of FIG. 5 , the reverse portion 40 extends perpendicular to the first portion 20 and the second portion 30 .
[0037] Figure 2A second exemplary embodiment of a spiral charging cable 10 for an electric vehicle is shown. The charging cable 10 has at least one first portion 20. In the at least one first portion 20, the charging cable 10 has at least one turn. In the at least one first portion 20, the longitudinal axis of the charging cable 10 extends in a first direction. The charging cable 10 has at least one second portion 30. In the at least one second portion 30, the charging cable 10 has at least one turn. In the at least one second portion 30, the longitudinal axis of the charging cable 10 extends in a second direction. The charging cable 10 has at least one reverse portion 40. At least one reverse portion 40 connects at least one first portion 20 and at least one second portion 30 together. At least one reverse portion 40 extends in a reverse direction. The reverse direction is different from the first direction and / or the second direction. Figure 2 In the example shown, the reverse direction is different from both the first direction and the second direction. Figure 2 In the illustration, the first reverse direction is perpendicular to the first direction and the second direction, that is, extends in the vertical direction.
[0038] Reference Figure 2 , a second exemplary embodiment of the charging cable 10 will be described more precisely as follows. It should be noted that Figure 2 In the exemplary embodiment of the present invention, only one first portion 20, one second portion 30 and one reverse portion 40 are shown by way of example. However, in a variant, more than one first portion 20, more than one second portion 30 and / or more than one reverse portion 40 may be provided in the charging cable 10.
[0039] In the first lead-out portion 50, the charging cable 10 extends straight / unwound (without turns) in its longitudinal direction. The length of the first lead-out portion is denoted as LA. The first charging cable 10 flows into the first portion 20 from the first lead-out portion 50. In the first portion 20, the charging cable 10 is spirally wound and forms a spiral shape as it originally did. The first portion 20 may also be referred to as a first spiral portion or a first winding portion 20. The length of the first spiral portion 20 may also be referred to as a block length. The spiral in the first spiral portion 20 is wound along a first winding direction, as viewed from the first lead-out portion 50 in a direction toward the first spiral portion 20. Figure 2 In the exemplary illustration, it is clockwise (left winding or left-hand winding).
[0040] exist Figure 2 In the exemplary embodiment of FIG. 1 , the straight-line reverse portion 40 extends perpendicularly to the first spiral portion 20 at one end of the first spiral portion 20 . In the reverse portion 40 , the charging cable 10 is not wound, that is, no turns exist in the charging cable 10 .
[0041] The second portion 30 is formed again perpendicular to the reverse portion 40 and parallel to the first spiral portion 20, in which the charging cable 10 is spirally wound and formed into a spiral shape as it was originally. The second portion 30 can also be referred to as a second spiral portion or a second winding portion 30. After the second winding portion 30, the second lead-out portion 60 of the charging cable 10 extends straight / unwound (without turns) in the longitudinal direction of the charging cable 10. The spiral in the second spiral portion 30 is wound along the second winding direction, as viewed from the second lead-out portion 60 in the direction toward the second spiral portion 30. Figure 2 In the exemplary representation of , the first winding direction of the helix in the first helical portion 20 and the second winding direction of the helix in the second helical portion 30 are different, i.e., the first winding direction corresponds to the clockwise winding direction, and the second winding direction corresponds to the counterclockwise direction.
[0042] If the charging cable 10 is viewed from the reverse portion 40, that is, Figure 2 In the configuration shown in the example, when viewed from the right side, the first spiral portion 20 is located to the left of the reverse portion 40, and the second spiral portion is also located to the left of the reverse portion 40. Figure 2 When viewing the charging cable 10 at the reverse portion 40, the first spiral portion 20 and the second spiral portion 30 are located on the same side of the reverse portion in the horizontal direction. However, the first spiral portion 20 and the second spiral portion 30 are located at different positions in the vertical direction.
[0043] Therefore, in summary, it can be said that in the first spiral portion 20, the charging cable is wound, for example, clockwise to show a first winding direction. In the second spiral portion 30, the charging cable is wound counterclockwise to show a second winding direction. Figure 2 In the first exemplary embodiment, the winding direction of the spiral in the first section 20 is, for example, different from the winding direction in the second section 30, that is, the first and second winding directions do not correspond, but are offset from one another. In other words, in the first section 20 and the second section 30, the spirals formed by the winding of the charging cable 10 each have opposite winding directions.
[0044] In addition, Figure 2 In the first exemplary embodiment, the first portion 20 and the second portion 30 are parallel to each other but extend offset in the vertical direction. Figure 2 In the first exemplary embodiment, the length of the first portion 20 corresponds to the length of the second portion 30, i.e. the block length. Figure 2In the exemplary embodiment of the present invention, the reverse portion 40 connecting the first portion 20 and the second portion 30 together is in the form of a straight portion. In the straight portion, the charging cable is not wound / has no turns. Figure 2 In the exemplary embodiment of FIG. 5 , the reverse portion 40 extends perpendicular to the first portion 20 and the second portion 30 .
[0045] exist Figure 1 and Figure 2 In the two exemplary embodiments, exactly one first portion 20 and exactly one second portion 30 are provided in each case. However, configurations with more than one first portion 20 and more than one second portion 30 are also conceivable, that is, a plurality of first portions 20 and a plurality of second portions 30 can be provided. The number of first portions 20 can correspond to the number of second portions 30, but the number of first portions 20 and second portions can also be different.
[0046] According to a first conceivable variant, the inverting portions can in each case be arranged in the same direction relative to one another, for example in the same inverting direction. In other words, the inverting directions of the inverting portions of the plurality of inverting portions between a first portion of the plurality of first portions and a second portion of the plurality of second portions can in each case extend parallel to one another.
[0047] When applied to Figure 1 In the example of , this means that the other reverse portion 40 can extend upward from the second lead-out portion 60 in parallel with the first reverse portion 40. The other first portion 20 can extend from the other reverse portion 40 in parallel with the first portion 20 - according to Figure 1 Extend to the right. Figure 1 In this case, the further portion 20 is parallel to and above the second portion 30. In this way, the charging cable 10 can be made particularly flat.
[0048] When applied to Figure 2 In the example of , this means that the other reverse portion 40 can extend upward from the second lead-out portion 60 in parallel with the first reverse portion 40. The other first portion 20 can extend from the other reverse portion 40 in parallel with the first portion 20 - according to Figure 2 Extend to the right. Figure 2 In this case, the further portion 20 is parallel to and above the second portion 40. In this way, the charging cable 10 can be made particularly flat.
[0049] According to a second variant, which can also be combined with the first variant with respect to some of the reversing sections, the reversing directions of the reversing sections of the plurality of reversing sections between a first section of the plurality of first sections and a second section of the plurality of second sections can each be arranged / oriented at an angle to one another. This angle can in particular be 90°. Other angles are also conceivable.
[0050] When applied to Figure 1 In the example of , this means that the further reverse portion 40 can extend forward (out of the drawing) or backward (into the drawing) from the second lead-out portion 60 at a certain angle (e.g. 90°) to the first reverse portion 40. The further first portion 20 can in turn extend from the further reverse portion 40 in parallel to the first portion 20 - according to Figure 1 Extend to the right. Figure 1 In this case, the further part 20 is located in front of or behind the second part 30 in the plane of the drawing and is parallel to the second part 20. In this way, the charging cable 10 can be arranged in a particularly compact manner.
[0051] When applied to Figure 2 In the example of , this means that the further reverse portion 40 can extend forward (out of the drawing) or backward (into the drawing) from the second lead-out portion 60 at a certain angle (e.g. 90°) to the first reverse portion 40. The further first portion 20 can in turn extend from the further reverse portion 40 in parallel to the first portion 20 - according to Figure 2 Extend to the right. Figure 2 In this case, the further part 20 is located in front of or behind the second part 30 in the plane of the drawing and is parallel to the second part 20. In this way, the charging cable 10 can be arranged in a particularly compact manner.
