Description
[0001] DESCRIPTION
[0002] Title: Cable connection device for electric charging station
[0003] Technical field
[0004] The present invention relates to the field of vehicle charging stations. The present invention relates more particularly to a cable connection device for a charging terminal of a charging station.
[0005] The present invention also relates to a charging station equipped with such a connection device.
[0006] Prior art
[0007] Electric vehicles must be charged regularly at charging stations, which are infrastructures equipped with one or more charging terminals. Each charging station includes at least one charging cable with a plug, forming a charging point, the plug being also called a "charging gun". Vehicles are then charged by connecting the charging cable plug to a corresponding charging socket on the vehicle.
[0008] Since the position of the charging socket varies depending on the electric vehicle, as does the parking of the electric vehicle in relation to the charging station, the charging cable must be of sufficient length to be able to be coupled to the electric vehicle. This is particularly important for a charging station associated with a parking lot, because the electric vehicle must be oriented according to the parking space, and the charging cable must be of sufficient length to reach the vehicle's charging socket, in any possible position of the electric vehicle.
[0009] This length poses several problems. In particular, when the charging cable rests on the ground, for example during use or due to improper handling of the cable, it is likely to be damaged, for example by being crushed by a vehicle or by a person tripping over the cable. The charging cable plug can also be damaged if it is dropped, or it can be contaminated by dirt from the ground. Furthermore, the existence of several global automotive markets, with a variety of standards and manufacturers, results in a wide variety of charging cable plug formats. This variety must therefore be reflected on the charging stations to make them compatible with vehicles from these different markets. For example, it is known to equip a single charging station with a plurality of charging cables, each charging cable having a plug specific to a given standard.
[0010] Each charging cable is an integral part of the charging stations, meaning they form a single, inseparable system. The charging cables are fixed integrally to a connection terminal block inside the charging stations. The charging cables are thus made in one piece, running from the terminals of the connection terminal block to the charging cable plug. The cables therefore pass through a side or front wall of the charging station, through an opening provided for this purpose. The cables are held in place in relation to the opening by a clamping system, in particular a cable gland type system, ensuring the passage of the cable, its mechanical locking, and the sealing of the charging station.
[0011] So, although it is possible to replace a charging cable, particularly to make the charging station compatible with a vehicle's charging socket standard, or to change a damaged or defective charging cable, replacing the charging cable is a complex operation. This complexity comes partly from the integration of the charging cable into the charging station, and from the connection of the charging station to the electrical network.
[0012] In practice, replacing a charging cable requires a cut in the general power supply, a partial dismantling of the charging station, in particular to access its connection terminal, an operation inside the charging station to uncable the defective or incompatible charging cable and to wire the replacement charging cable, a reassembly of the charging station and finally a restart of the complete electrical installation. All of these operations thus put all the charging stations in the electrical installation out of service and require the intervention of authorized operators.
[0013] Replacing a charging cable for a charging station, according to the current design of the whole, therefore causes significant disruptions which result in a loss of productivity of the installation for the operator and a loss of availability of the charging stations for the user.
[0014] Another solution, proposed by document W02020201616, consists of proposing a mechanical system for arranging the charging cable in relation to the charging station, so that the charging cable extends vertically in its rest position, the charging cable being able to deform under the action of a user. Such a solution is however not entirely satisfactory because it does not guarantee the physical integrity of the cable, in particular when it is in use, and therefore has been deformed out of its rest position by a user. This solution also does nothing to resolve the compatibility problems between the different charging cable standards.
[0015] For these reasons, the Applicant submits that the prior art solutions are not fully satisfactory because they are not adapted to the risks and needs associated with the use of vehicle charging stations.
[0016] Summary of the invention
[0017] The present invention aims to improve the situation described above.
[0018] The present invention aims more particularly to remedy the above drawbacks by proposing a cable connection device for an electric vehicle charging station, the device minimizing the disruptions associated with replacing the cable, while preserving the electrical properties and limiting the external size of the charging station.
[0019] One solution proposed to overcome these drawbacks is to implement an external connection system, of the male-female type, of the charging cable on the charging station. In this way, the replacement of the charging cable corresponds to a simple connection, which can be carried out quickly and safely, without requiring any tools or special qualifications. However, given the current intensity required for charging, existing male-female plug systems, corresponding to high-power connectors, do not have sufficient internal volume to connect a charging cable. In addition, this design increases the space occupied by the charging station, due to the offset of the cable from the station.An object of the present disclosure is to provide a robust, reliable and fast cable management device for an electric vehicle charging station so as to replace the charging cable while preserving the electrical properties, reducing the downtime of the installation to zero and limiting the external size of this device. The replacement of the charging cable meets a need for repairability of the latter (defective charging cable) and / or compatibility with the vehicle presented for charging (different charging plug format).
[0020] To this end, the subject of the present invention relates, according to a first aspect, to a device for electrically connecting a charging cable to an electrical charging terminal, the device comprising:
[0021] - a first body having a first face provided with a first connection interface compatible with a second connection interface provided on the terminal, the first body also having a second face provided with at least one housing sized for receiving a wire of the cable, the first body being configured to ensure a passage of current between the wire and the first connection interface when the wire is received by the housing; and
[0022] - a second body having a third face provided with a first opening opening onto an internal space of the second body, the second body also having a fourth face provided with a second opening sized for receiving a first end of the charging cable, the second opening opening onto the internal space.
[0023] It is understood here that the first end of the charging cable is received so as to make the cable integral with the second body. The device comprises, for example, a cable gland type clamping system for the cable with respect to the second opening. The clamping system thus ensures the sealing of the second body and the mechanical locking of the cable relative to the device.
[0024] It is further understood that the first body is dimensioned on the one hand for receiving one or more wires of the charging cable, for example the set of wires making up the charging cable, and on the other hand for fixing it to an electric charging terminal by matching the first interface and the second interface. The design of the first body is therefore adapted according to the formats, in particular the formats known to those skilled in the art, of connection interfaces and cables in the field of vehicle charging stations. The first body corresponds for example, as described below, to a male plug known to those skilled in the art, for example a high-power connector, and allowing the reception of all the wires making up the charging cable. The association of the device on the charging terminal corresponds for example to a simple connection between the two connection interfaces.
[0025] Advantageously, the first body and the second body are associated via the second and third faces, so that the housing of the first body communicates with the internal space of the second body.
[0026] It is understood here that, when using the device, the second body receives the first end of the charging cable, the charging cable then being separated into a plurality of wires within the internal space. The separated wires are then received in respective housings of the first body, which are accessible in the internal space by matching the second face with the third face.
[0027] The person skilled in the art further understands that the internal space provides sufficient volume to allow the separation of the wires of the charging cable and their positioning in the housings of the first body while respecting the radius of curvature of each wire.
[0028] Thanks to the present invention, the electrical connection device allows the removable connection of a charging cable with an electrical charging station, by simply connecting the first interface to the second interface. The charging cable can then be easily detached from the charging station, for example for its replacement in the event of a fault or its substitution with another charging cable, in particular another charging cable having a different charging plug.
[0029] In an advantageous embodiment of the present invention, the first face extends in a first plane and the device extends substantially along a first axis orthogonal to the first plane, and the fourth face extends along a fourth plane oriented at an acute angle to the first plane, such that the charging cable is received by the second opening along a second axis oriented at the acute angle to the first axis.
[0030] According to a first example, the first face, the second face and the third face each extend in parallel planes. According to a second example, the first face, the second face and the third face extend along progressively inclined planes so as to progressively reach the acute angle.
[0031] For the purposes of the present invention, an acute angle is understood to mean here and throughout the following description a non-zero angle between the second axis and the first axis, the measurement of which in degrees is less than 90°. Obviously, such an acute angle is to be differentiated from a clearance or a design tolerance in a coaxial or perpendicular assembly.
[0032] In other words, the charging cable is received by the electrical connection device along a second axis that is not coaxial and not perpendicular to the first axis, i.e. to a longitudinal direction along which the device extends, making it possible to at least partially reorient the charging cable with respect to this longitudinal direction upon its assembly with the electrical connection device. In particular, the first face having the first connection interface, the first axis also corresponds to the axis along which the device extends when the device is received on a charging station. The direction of the charging cable is already at least partially reoriented with respect to the electrical charging station and the length requirement resulting from the radius of curvature of the cable is reduced.
[0033] In particular, the design of the device providing a volume greater than existing male-female plug systems, the offset of the cable relative to the terminal is all the more impacted, and its extension of the device along the second axis makes it possible to minimize the overall length requirement, in particular so as not to require more free space around the charging terminal than a design according to the prior art.
[0034] The skilled person further understands that the internal space of the second body allows for the separation of the charging cable into a plurality of wires, each individual wire having a radius of curvature smaller than that of the charging cable. The second body may therefore be sized to allow for the orientation of the cable along the second axis, with any additional offset resulting from this sizing being offset by the total space gain resulting from the new orientation of the charging cable.
[0035] In an additional embodiment, the second axis is oriented at an angle of between 10° and 80° relative to the first axis. Preferably, the second axis is oriented at an angle of between 30° and 60° relative to the first axis.
[0036] Preferably, the second axis is oriented at an angle substantially equal to 45° relative to the first axis.
[0037] It is understood here that the choice of angle is made according to the design constraints, in particular the set of positions expected of the charging cable with respect to the charging terminal, during its use, that is to say the connection of the plug of the charging cable to a charging socket of a vehicle.
[0038] Depending on the axis of rotation with respect to which the second axis is oriented relative to the first axis, the choice of angle may also depend on the positioning of the connection device according to the height of the charging station, relative to the height of a charging socket of an electric vehicle. For example, an orientation at a lower angle is provided for positioning the device at a height substantially close to a charging socket of the vehicle, and a higher angle for positioning the device at a height further from a charging socket of the vehicle, so that the charging cable extends naturally from the charging station towards the charging socket.
[0039] In a specific embodiment, the second body and / or the first body have a third opening formed along a side wall, the device further comprising a cover forming a negative of the third opening and means for removably fixing the cover to the third opening, the cover being associated with the third opening in a removably manner, so that the cover closes the third opening and can be dissociated from the third opening.
[0040] Preferably, the third opening is formed along the side wall of the second body. According to an alternative embodiment, the third opening is formed partially by the second body and partially by the first body, the third opening being formed by the association of the first body with the second body.
[0041] It is understood here that the cover, when dissociated from the third opening, allows direct access to the internal space, in particular to allow the connection of the wires of the charging cable in the housings, or simply for a visual check of such a connection. The cover is for example associated with the third opening via removable fixing means, for example via a set of screws allowing the release of the third opening with simple tools. According to another example, the cover is articulated with respect to the third opening, for example via a hinge, allowing access to the internal space without any particular tool.
[0042] In an additional embodiment, the first body comprises a cavity formed along the second face, the cavity having the housing.
[0043] In other words, the first body has a hollow structure containing the at least one housing, the association of the first body and the second body creating a volume formed by the internal space of the second body and the cavity of the first body.
[0044] It is thus understood that the device, in particular the second body, is sized so that the wires coming from the charging cable can be reoriented in the volume formed by the internal space and the cavity and received in the dedicated housings of the first body.
[0045] In yet another embodiment, the first body corresponds to a male plug sized for current passage between the wire and the first connection interface when the wire is received by the housing.
[0046] In other words, it is understood here that the device is formed by the association of a male plug, for example whose design corresponds to an existing male-female socket system, in particular to a high-power connector, with a second body forming an extension adapted for receiving the charging cable, that is to say the extraction of all the wires of the charging cable and their positioning in the housings of the male plug, by providing an internal volume allowing the radius of curvature of each of these wires to be respected. The second connection interface corresponds for example to a female plug complementary to the male plug, of the same existing male-female socket system.
[0047] In an additional embodiment, the device further comprises means for fixing the first body and the second body according to the second face and third face.
[0048] It is understood here that the first body and the second body form two separate elements, the fixing means allowing the first body and the second body to be combined for the assembly of the device. This design allows in particular a simple production of the device according to the invention, for example by combining a male plug, known to those skilled in the art, with a second body sized so as to correspond to the male plug and forming an extension of the male plug. The fixing means correspond for example to a set of screws passing through dedicated openings provided according to the first body and the second body. More generally, this design allows a simplified production of the device by separate manufacture of the first body and the second body, then assembly. This design allows the first body and the second body, in particular the housing and the internal space, to be produced without difficulty.
[0049] In another embodiment, the first body and the second body form a single-piece assembly.
[0050] It is understood here that this embodiment corresponds to a design of the device in a single main part, the first body and the second body corresponding to two adjacent portions of the device and the second face and third face to two cross sections of the device. Those skilled in the art also understand that this design also comprises means allowing the reception of the wires of the charging cable in the at least one housing, for example a third opening as described above allowing access to the internal space of the device.
[0051] In an additional embodiment, the device is sized to pass a current greater than or equal to 16A.
[0052] Preferably, the device is sized for the passage of a current greater than 100 A.
[0053] We understand here that a current of 16A corresponds to a standard recharge, of approximately 3kW and based on European standards for domestic electrical installations, combining a voltage of 230V with an amperage of 16A.
[0054] A current greater than 100 A corresponds to the standards for rapid direct current charging, for example the CCS standard (from the English "Combined Charging System"), in particular CCS 1.0 or CCS 2.0, based on a voltage of 850V with an amperage of 200A for a charge of approximately 170 kW, or even a charge of 350 kW via a voltage of 920V and an amperage of 500A, or the CHAdeMO standard (from the English "Charge de Move" or in French "movement by charge"), allowing a charge between 50kW and 62.5kW under 500V and 100A to 125 A, or even up to 400kW under 1000V and 400A in direct current. According to one variant, the device is sized for a fast AC charging standard, in particular for a charging power of 43 kW at 400V and 63 A.
[0055] It is understood here that the sizing of the device is associated with the sizing of the wiring allowing the passage of the desired current, higher amperages requiring cables with a larger cross-section. The standard associated with the device also determines, for example, the number and type of wires in a cable, and therefore the number of associated housings for the first body, as well as their size. The device is, for example, sized to allow the reception of a variety of cables according to the different charging standards known to those skilled in the art.
[0056] A second aspect of the present invention relates to a charging cable for an electric charging station, the cable having a first end provided with an electrical connection device according to the first aspect of the invention, the cable having a second end provided with a plug.
[0057] It is understood here that the charging cable has a structure substantially similar to the charging cables known from the prior art. For example, a plurality of interchangeable charging cables are provided, each charging cable being provided with the device according to the invention and a plug associated with a charging standard from among a plurality of known standards.
[0058] A third aspect of the present invention relates to an electric charging terminal, the terminal comprising an external casing defining an internal volume, the external casing being provided with at least one second connection interface, the terminal comprising an electrical panel arranged in the internal volume and connected to the second interface, the terminal being configured to receive at least one electrical connection device according to the first aspect of the invention, via the second connection interface.
[0059] It is understood here that the charging station is designed in a manner compatible with the device according to the invention. The joint use of the charging station and the device according to the invention thus allows a removable connection of a charging cable, requiring no special tools and no disconnection of the general power supply for the replacement or exchange of the charging cable.
[0060] According to one embodiment, the terminal comprises at least one electrical connection device according to the first aspect of the invention and at least one charging cable according to the second aspect of the invention, so that the charging cable is electrically connected to the electrical panel via the electrical connection device and the second interface.
[0061] A fourth aspect of the present invention relates to a vehicle charging station, the station comprising at least one electric charging terminal according to the third aspect of the invention.
[0062] Thus, through the various functional and structural characteristics above, the Applicant proposes an electrical connection device adapted on the one hand to its removable connection on an electric charging station, and on the other hand to the secure reception of a charging cable. This device thus allows easy replacement of the charging cables on the charging stations, in a manner adapted to the needs in terms of repairability and compatibility of the charging cables.

[0069] Figure 5 represents a schematic view of a second body of an electrical connection device according to Figure 1;
[0070] Figure 6 shows an electrical connection device according to a second exemplary embodiment of the present invention. Detailed description
[0071] The present invention will now be described in the following with reference to Figures 1 to 6 attached to the description. The same elements are identified with the same reference signs throughout the description which follows.
[0072] As stated in the preamble to the description, current solutions for connecting a charging cable to a vehicle charging station do not allow for rapid and secure replacement of the cable in the event of damage, incompatibility or even a change of cable model.
[0073] One of the objectives of the present invention is to make it possible to easily connect and disconnect an electric cable from a charging station, without requiring a complex operation or special authorization.
[0074] As illustrated in Figure 1, in the example described here, an electric charging terminal 3 is provided, for example inside a public or private charging station, receiving a charging cable 2 via an electrical connection device 1. The charging station comprises, for example, a plurality of charging terminals 3 arranged at regular intervals, each charging terminal 3 allowing the charging of one or more vehicles.
[0075] Electric charging station 3 corresponds, for example, to a rapid charging station, configured to operate at high power, for example between 50kW and 400kW.
[0076] The charging cable 2 extends between a first end 20a receiving the electrical connection device 1 and a second end 20b receiving a plug or charging gun 21. In this figure, the charging cable 2 and the charging gun 21 correspond to the CCS 2.0 fast charging standard.
[0077] In this example, and as described in figures 2 to 6, the electrical connection device 1 comprises a first body 10 and a second body 11. The first body 10 has a first connection interface 103, on a first face illustrated by figures 4 and 6, allowing its connection to a second connection interface 31 provided on the rapid charging terminal 3.
[0078] The first body 10 also has a second face provided with at least one housing 104, each housing 104 receiving a wire of the charging cable 2. The number and the section of the housings 104 depend on the charging cable 2, and therefore on the charging standard. The first body 10 is provided with housings 104 corresponding to a plurality of different charging standards, allowing the wiring of different charging cables 2 on the same device 1. The example of figures 2 to 4 corresponds for example to the CSS 2.0 standard, in accordance with the charging cable 2 and the charging gun 21 of figure 1.In this example, the second face is provided with first housings having a first section, corresponding to a positive terminal and a negative terminal and allowing the circulation of a direct current, a second housing having a second section and corresponding to an earthing, as well as third housings having a third section and corresponding to the proximity signal and the control signal. For example, a plurality of fourth housings associated with small section wires are also provided, each housing and each wire corresponding to one or more pieces of information that can be transmitted during recharging via the charging cable 2, for example information from sensors integrated into the charging cable 2 or the charging gun 21 and making it possible to ensure the proper functioning of the recharging.The housings 104 allow communication with the first interface 103, so that a wire received by a housing 104 enters into electrical connection with the charging terminal 3, when the device 1 is connected to the second interface 32.
[0079] In this same example, the housings 104 are arranged in a cavity 105, or recess, on the second face, so that the housings 104 do not form protrusions on the second face. This design makes it possible to maximize the internal space of the device 1 for a given total length, or vice versa to minimize the length of the device 1 with respect to the space necessary to make the connection.
[0080] The first body 10 corresponds for example, or has a substantially similar structure, to a male plug sized for the passage of a current associated with the charging cable 2, or more generally sized in accordance with the male-female socket standards existing in the field. Like the first body 10, the second connection interface 31 corresponds for example to a female plug complementary to such a male plug. The first body 10 and the second connection interface 31 correspond for example to a pair of male and female power connectors, commonly used by those skilled in the art for example for panel or box mounting, in particular in the context of test benches.As illustrated in Figures 2 to 4, the first body 10 comprises for example a housing 101 having the first face and the second face, the housing 101 being at least partially surrounded by a flange 102 of suitable shape to allow the connection of the first body 10 to the charging terminal 3.
[0081] In addition to the first body 10, a second body 11 is also provided which is part of the device 1. The second body 11 has a third face 111 provided with a first opening 112 (figure 5), and a fourth face 113 provided with a second opening 114 (figures 3 and 6). The first opening 112 and the second opening 114 open onto an internal space of the second body 11. The fourth opening 114 allows the charging cable 2 to be received at its first end 20a, for example via clamping means 119 of the cable gland type.
[0082] The first body 10 and the second body 11 are associated with each other via the second face and the third face 111. In other words, the first body 10 and the second body 11 are brought into contact, the first opening 112 allowing communication between the internal space and the housing 104.
[0083] In a first embodiment illustrated in Figures 2 to 5, the first body 10 and the second body 11 form two separate elements assembled together via fixing means 12. According to the example of Figure 3, the first body 10 and the second body 11 are assembled via four screws forming the fixing means 12 and arranged around the periphery of the second face. The assembly between the first body 10 and the second body 11 is sealed, to ensure the safety of the connection device 1. The second body 11 corresponds for example to a part designed to be associated with a male plug known to those skilled in the art and forming an extension of this male plug.
[0084] In a second embodiment illustrated in Figure 6, the first body 10 and the second body 11 form a single-piece assembly, that is to say they are made in a single piece, the first body 10 and the second body 11 then corresponding to two adjacent portions of the single-piece assembly, the second opening 114 allowing access to the internal space up to the housing 104.
[0085] The charging cable 2 is therefore received via the fourth opening 114, and can be separated into several wires in the internal space, each wire being separately received by a housing 104 of the first body. Each wire having a section smaller than the total section of the charging cable 2, their individual bending radius is smaller. It therefore becomes possible to arrange them advantageously inside the device 1, minimizing the required length. The Applicant further submits that existing male-female plug systems do not have sufficient internal volume to directly receive and separate the wires of a charging cable 2. The device 1 according to the invention allows such separation entirely inside the internal space, ensuring a safe structure that can be arranged outside the charging station 3.
[0086] It is also understood that the device 1, in particular the second body 11, is sized according to the number and the section of the wires of the charging cable 2, that is to say in such a way as to respect the radius of curvature of each wire for its separation and its positioning in the dedicated housing 104.
[0087] In particular, in this same example, the fourth face 113 is arranged at an angle relative to the first face, as well as relative to the second face and the third face 111. According to the example of FIGS. 2 and 3, the fourth face is arranged substantially at 45° relative to the first face, second face and third face. The charging cable 2 therefore extends at this angle relative to the device 1, and by extension relative to the charging terminal 3. This design makes it possible to minimize the size resulting from the radius of curvature of the charging cable 2, in particular compared to a coaxial assembly. Furthermore, the separation of the charging cable 2 into several wires in the internal space makes it possible to take advantage of a smaller radius of curvature to orient the charging cable 2 according to the angle, minimizing the constraints on the dimensions of the connection device 1.This design thus makes it possible to minimize the size resulting from the addition of the connection device 1, in comparison with the solutions of the prior art in which the charging cable 2 extends directly from the charging terminal 3.
[0088] Optionally, the device 1 has a third opening 115 formed along a side wall. According to the example of FIG. 3, the third opening 115 is formed along a side wall of the second body 11. The side wall corresponds for example to a wall adjacent to the first face and / or to the second face and / or to the third face 111 and / or to the fourth face 113, or more simply to a wall connecting two faces of the device 1. According to another example, the device 1, for example the first body 10 and / or the second body 11, has a substantially cylindrical shape, the side wall corresponding to a portion of the periphery of the cylindrical shape. In addition to the third opening 115, a cover 116 is provided which is removably attached to the device 1. The cover 116 forms a negative of the third opening 115, i.e. the cover 116 covers and closes the third opening 115 when the cover 116 is attached to the device 1.In this same example, the cover 116 is fixed to the device 1 via a plurality of screws 117 arranged along the edge of the cover 116, the cover 116 having a surface area greater than that of the third opening 115. Thus, the cover 116 can be removed to view the arrangement of the wires in the device 1, and in particular to check that each wire is arranged in a corresponding housing 104. Also provided in this same example is a seal 118 ensuring the sealing of the fixing of the cover 116. Obviously, a variety of other means of assembling the cover 116 with the third opening 115 can be provided, making it possible to remove, raise or even slide the cover 116 so as to release the third opening 115.
[0089] Thus, it will be understood that the present invention provides a device for electrically connecting a charging cable, making it possible to receive a charging cable on the one hand and to be connected on the other hand to an electrical interface compatible with the wires of the charging cable, in particular to an electrical interface of an electric charging station.
