Description

Title of the invention: Quick connection device for electric vehicle charging station and electric vehicle charging station comprising at least one such device

[0001] The present invention relates to the field of electric vehicle charging stations and relates to a quick-connect device for an electric vehicle charging station. It also relates to an electric vehicle charging station comprising at least one such connection device.

[0002] To recharge the battery, also called the accumulator, of an electric vehicle, individuals and professionals are increasingly using charging stations fixed to a permanent support such as a wall. These allow for shorter charging times (higher charging speeds) and higher charging power than with ordinary sockets, and are safer.

[0003] Such a charging station is supplied with alternating current by an electrical distribution network and includes the circuits and socket(s) necessary to supply the battery to be recharged with a direct current adapted to the characteristics of the battery.

[0004] More particularly, the charging station includes a housing delimiting an internal space, at least one electronic board (PCB) fixed in the internal space, at least one charging socket dedicated to charging the storage battery of an electric vehicle and fixed to the housing or connected to the end of a charging cable coming out of the housing.

[0005] Hereafter, the charging socket or sockets fixed to the housing are referred to (or defined as) as a fixed charging socket, also known as a charging socket or power socket. The charging socket or sockets connected to the end of the charging cable are referred to (or defined as) as a mobile charging socket, also known as a pistol grip or pistol grip.

[0006] Such a fixed or mobile charging socket is a female socket that allows the charging station to be electrically connected to a standard male charging socket of an electric vehicle. In the case of a fixed charging socket, it is connected, via a flexible male-to-female charging cable, to the electric vehicle's charging socket. The charging cable has a male plug at one end for connecting to the female fixed charging socket(s) of the charging station and a female plug at the other end for connecting to the standard male charging socket of the electric vehicle being charged. In the case of a mobile charging socket, it is connected directly to the male charging socket of the electric vehicle.

[0007] These fixed or mobile charging sockets are standard components that comply with the relevant standards and regulations. For example, the Type 2 charging socket is the European standard required for all charging stations and all-electric or hybrid electric vehicles sold in the European Union. It comprises a housing and, on the front side of the housing, a plurality of output pins and, on the rear side of the housing, a plurality of rigid conductors. The conductors are held in the housing in a fixed position relative to each other and are each connected to one of the output pins. The conductors are further connected, via flexible electrical cables, to the charging station's electronic board to electrically connect the output pins to the board.

[0008] More particularly, the charging socket includes a set of control output pins, generally two control output pins ("proximity pilot" (PP) and "Control Pilot" (CP)), for communication between the charging station and the electric vehicle to be charged, in particular to determine the maximum current level supported by its battery and to intelligently allow the flow of current from the charging station and a set of power output pins, generally five power output pins (one ground pin, one neutral pin and three phase pins) to supply the current and power to the battery of the electric vehicle to be charged.

[0009] However, a problem encountered with these charging stations is the connection of the charging plug conductors to the electronic board, which is made using flexible electrical cables. These cables must be attached to the conductors with clamping screws and to the electronic board via a junction box, which is itself soldered to the board. This requires significant assembly and fastening time, as well as the use of specific tools, whether for assembly during factory production, on-site installation by the individual or professional, or during maintenance of the charging station. Furthermore, the cost of raw materials, particularly copper, in the electrical cables results in high manufacturing costs and production costs.Furthermore, for a private or professional installer, these operations are demanding and difficult to perform, and can lead to risks of overheating or even fire, for example, when the tightening torque of the screws is not correctly applied and / or controlled by the installer. Finally, the complexity of securing the electrical cables limits the possibility of mass-producing charging stations in factories within short timeframes.

[0010] Document WO 2020 / 167141 proposes a solution aimed at addressing at least some of these problems created by current charging sockets from which the Cables for connecting the pins / conductors to the PCB in charging stations. This document relates to a charging station terminal for an electric vehicle charger, said terminal being mounted on an electronic board (printed circuit board (PCB)) to form a single unit. The terminal conforms to a standard Type 2 charging socket and has a plurality of power and control output pins (carrying control signals), a plurality of conductors each connected to one of the output pins, and to the PCB to connect the output pins to the latter. A support receives the conductors, holding them in a fixed position relative to each other. The terminal also incorporates features found in current charging sockets, such as a locking motor to secure the charger to the electric vehicle charging cable during charging.

[0011] However, while the terminal assembly disclosed by document WO 2020 / 167141 eliminates the need for cables and the manual work of connecting them, and avoids screwing operations in particular, it does not offer a simple solution. Instead, it requires a complex set of parts to manufacture and assemble together and on the PCB to recreate all the functionalities of a standard charging socket, particularly a type "2" socket, i.e., including features such as the socket locking motor. Furthermore, maintenance operations in the event of damage to a component, such as a pin, a conductor, or the locking motor, require replacing the entire terminal assembly, which is manufactured as a single piece / block.

[0012] The present invention aims to overcome these drawbacks by providing a quick connection device for electric vehicle charging stations, enabling production time savings, reduced manufacturing and maintenance costs, simplified factory and on-site assembly operations during installation or maintenance of the charging station, while reducing the risks of incorrect wiring.

[0013] To this end, the quick-connect device according to the present invention for an electric vehicle charging station, said charging station comprising a housing delimiting an internal space, at least one electronic board fixed in the internal space, at least one charging socket dedicated to charging the storage battery of an electric vehicle, each charging socket being either fixed by being attached to the housing, or mobile by being connected to the end of a charging cable exiting the housing, said fixed or mobile charging socket comprising power and / or communication output pins and conductors each connected to one of these pins, the other end of the charging cable terminating in connection points each connected to one of the conductors of the charging socket mobile, is essentially characterized in that it includes suitable connection interfaces, each intended to functionally connect the electronic board to one of said conductors or connection points, and each comprising a first connector equipped with a suitable fixing and connection tip intended to be connected and secured to the conductor or connection point concerned and a male or female connection tip, and a second connector equipped with a suitable fixing and connection tip intended to be connected and secured to the electronic board and a suitable male or female connection tip intended to be connected to the connection tip of the first connector by mutual interlocking of said connection tips.

[0014] The present invention also relates to an electric vehicle charging station, said charging station comprising a housing delimiting an internal space, at least one electronic board fixed in the internal space, at least one charging socket dedicated to charging the storage battery of an electric vehicle, each charging socket being either fixed by being fixed to the housing, or mobile by being connected to the end of a charging cable exiting the housing, said fixed or mobile charging socket comprising power and / or communication output pins and conductors each connected to one of these pins, the other end of the charging cable terminating in connection points each connected to one of the conductors of the mobile charging socket,the conductors of the fixed charging socket or the connection points of the charging cable being connected within the electronic board by means of a connection device, essentially characterized in that the connection device consists of a connection device according to the present invention and in that the fixing and connection tip of each first connector is connected and secured to the conductor or connection point concerned and the fixing and connection tip of each second connector is connected and secured to the electronic board, the male or female connection tip of each second connector being connected to the male or female connection tip of the first connector by mutual interlocking of said connection tips.

[0034] [Fig. 18] is a perspective view of the charging station shown on the [Fig. 14] with the front of the case closed.

[0035] The accompanying figures show a quick-connect device, according to the present invention, for an electric vehicle charging station. Such a charging station comprises:

[0036] - a housing B delimiting an internal space Bl,

[0037] - at least one electronic card 1 fixed in the internal space Bl,

[0038] - at least one charging socket 2 dedicated to charging the storage battery of an electric vehicle. The charging socket(s) 2 are either fixed, being attached to the housing B (as in Figures 1 to 12, 17), or mobile, being connected to the end of a charging cable C extending from the housing B (as in Figures 7 to 14, 15a, 15b, 16, 18). The charging cable(s) C are thus equipped at one of their ends, located outside the housing B, with the charging socket(s) 2. The other end of the charging cable(s) C is functionally connected inside the housing B, as will be seen later.

[0039] Each fixed or mobile charging socket 2 comprises, in a known manner, power and / or communication output pins 2a and conductors 2b each connected to one of these pins. The power output pins 2a each allow the passage of alternating current, each forming a phase, neutral, or earth. The power output pins 2b may comprise, as is the case with current standard charging sockets, three to five power output pins (one earth pin, one neutral pin, and one to three phase pins).The communication output pins 2a are control output pins (known for example by the English expressions "proximity pilot" (PP) and "Control Pilot" (CP)) for communication between the charging station B and the electric vehicle to be charged, in particular to determine the maximum current level that its battery can withstand and to intelligently allow the flow of current from the charging station B to the battery (or batteries or accumulator(s)) of the electric vehicle.

[0040] Such a fixed or mobile charging socket 2 is a standard component that meets the applicable standards. For example, such a charging socket 2 may be a type "2" charging socket, which is the European standard imposed on all charging stations and 100% electric or hybrid electric vehicles sold in the European Union. It comprises a housing 2c intended to be fixed to the housing B1 of the charging station B and, by making the output pins 2a accessible from the outside on a front side of the housing 2c, and the output pins 2a on a rear side of the housing 2c. conductors 2b. The conductors 2b are held in the housing 2c in a fixed position relative to each other.

[0041] In the case of a mobile charging socket 2 (connected to one end of a charging cable C exiting the housing B of a charging station B), the other end of the charging cable C (opposite to the end equipped with the mobile charging socket 2) terminates in connection points Cia, each connected to one of the conductors 2b of the mobile charging socket 2 (Figures 13, 14, 16). These connection points Cia ensure the electrical continuity of the conductors 2b to the other end of the charging cable Cl located in the internal space B1 of the charging station B.

[0042] According to the present invention, such a connection device according to the present invention comprises connection interfaces 3, 4, each suitable and intended to functionally connect the electronic board 1 (or one of the electronic boards 1 in the case where the charging station comprises a plurality of electronic boards 1) to one of said conductors 2b or connection points Cia. Such a functional connection made by the connection device between the conductors 2b of the fixed charging socket 2 and the electronic board 1, or between the connection points Cia and the electronic board 1, makes it possible to connect (electrically) the output pins 2a of the fixed or mobile charging socket 2 to said electronic board 1.Each electronic board 1 is in particular a printed circuit board (or PCB), that is to say a support, generally a plate, allowing a set of electronic components to be held and electrically connected together.

[0043] In accordance with the present invention, each connection interface 3, 4 comprises:

[0044] - a first connector 3 equipped with a suitable fixing and connection tip 3a and intended to be connected to and secured to the relevant 2b conductor or Cia connection point and a male or female 3b connection fitting,

[0045] - and a second connector 4 equipped with a suitable fixing and connection tip 4a and intended to be connected and attached to the electronic board 1 and to a suitable male or female connection tip 4b and intended to be connected to the connection tip 3b of the first connector 3 by mutual interlocking of said connection tips 3b, 4b.

[0046] It is understood that the number of connection interfaces 3, 4 depends on the number of output pins 2a to be connected to the relevant electronic board(s) 1. Note that, in such a charging station, not all output pins 2a are always connected to the electronic board 1.

[0047] A connection point Cia forms an end termination of the charging cable C and more particularly an end termination of one of the wires Electrical connection point C1 of the charging cable C connected to one of the conductors 2b of the mobile charging socket 2. Such a connection point C1 can be formed, in the first case, directly by the stripped end of one of the electrical wires C1 of the charging cable C (Figures 13, 14, 15a, 15b, 16). It can also be formed, in a second case not shown in the accompanying figures, by an electrical connection element connected to such a stripped end. Such an electrical connection element can be, for example, a cable ferrule or a ferrule that can be crimped onto the stripped end of the wire in question. In the first case, the fixing and connection tip 3a of each first connector 3 can be secured and connected, for example, by crimping or screwing, to the bare end Cia of one of the electrical wires Cl of the charging cable C (figures 13, 14, 15a, 15b, 16).In the second case, the fixing and connection end 3a of each first connector 3 can be secured and connected to the connecting element, for example by screwing.

[0048] The present invention may provide, as can be seen in particular in figures 13, 14 and 16, that the set of connection points Cia and the first connectors 3 connected and secured to them is mounted on a support S allowing the positioning and maintenance in a fixed position relative to each other of said first connectors 3. This positioning makes this connection set, and in particular the first connectors 3, ready to be quickly connected to the second connectors 4 connected and secured on the electronic board 1 to be connected.

[0049] As can be seen particularly in Figures 1, 2, 3 to 6, in a first embodiment of the male / female connection of the first and second connectors 3, 4, the connection tip 4b of each second connector 4 is a female connection tip 4b and the connection tip 3b of each first connector 3 is a male connection tip 3b. The female connection tip 4b of the second connector 4 has an axial receiving cavity 40b for receiving the male tip 3b of the first connector (Figures 4, 5 and 6 in particular). The material (metallic for example), dimensions and shape of the male connection tip 3b of the first connector 3 and of the axial receiving cavity 40b of the second connector 4 are determined so as to allow an electrical connection between the two connectors 3, 4.

[0050] As can be seen particularly in Figures 7, 8, 9 to 12 and 16, in a second embodiment of the male / female connection of the first and second connectors 3, 4, the connection tip 4b of each second connector 4 can be a male connection tip 4b and the connection tip 3b of each first connector 3 can be a female connection tip 3b. The female connection tip 3b of the first connector 3 has a receiving cavity 30b allowing the male connector 4b of the second connector 4 to be received (Figures 10, 11 and 12 in particular). The material (metallic for example), dimensions and shape of the male connector 4b of the second connector 4 and of the axial receiving cavity 30b of the first connector 3 are determined so as to allow an electrical connection between the two connectors 3, 4.

[0051] The male / female assembly / connection between each first connector 3 and the corresponding second connector 4, by mutually fitting their respective male / female connection tips 3b, 4b, allows for a quick mutual assembly / connection between said first and second connectors 3, 4 and therefore between the conductors 2b of the fixed charging socket, or the connection points Cia at the relevant end of the charging cable C, and the electronic board 1.

[0052] The fixed or mobile charging socket 2 can be connected, via the connection device according to the present invention, to one or more electronic cards 2, i.e. to a single electronic card 1 performing all the functions necessary for the fixed or mobile charging socket 2 for its connection to an electric vehicle or to several electronic cards 1 each performing at least one of said functions.

[0053] Referring in particular to Figures 1 to 12, it can be seen that each conductor 2b of the fixed charging socket 2 has, in a known manner, a socket or barrel shape. Each conductor 2b has an axial receiving cavity 20b. It can also be seen that the present invention can provide that the fixing and connection tip 3a of each first connector 3 is suitable and intended to be inserted (or embedded) in the receiving cavity 20b of the relevant conductor 2b of the fixed charging socket 2. It can also be seen that the connection device according to the present invention further comprises locking means 5 for securing the fixing and connection tips 3a and preventing their removal from the respective receiving cavities 20b of the relevant conductors 2b.

[0054] In the case of a mobile charging socket 2 (figures 13, 14, 16, 18 in particular), i.e. connected (and secured) to the end of a charging cable C coming out of the charging station C, the conductors 2b are identical or similar to those of a fixed charging socket 2.

[0055] In the case of a fixed charging socket 2, in a first embodiment of the locking means 5, as can be seen more particularly in Figures 6 and 12, each conductor 2b has at least one tapped hole 21b opening transversely into its receiving cavity 20b. In addition, the locking means 5 consist of at least one pressure screw 5 screwed into the tapped hole(s) 21b, its end 5a pressing against the external surface, said bearing surface, of the fixing and connection end 3a inserted into the receiving cavity 20b. Preferably, as can be seen in particular in Figures 7, 9, 10, the fixing and connection end 3a of each first connector 3 may have a flat 30a formed in its external surface, said flat 30a forming the bearing surface. The flat 30a prevents the rotation of the first connector 3 about its axis and, thanks to the flat surface of the flat 30a, improves the clamping pressure and thus strengthens the connection.

[0056] Still in the case of a fixed charging socket 2, in another embodiment of the locking means, not shown in the attached figures, the receiving cavity 20b of each conductor 2b is tapped and the fixing and connection tip 3a of each first connector 3 is threaded so as to allow its screwing into the receiving cavity 2b concerned, said thread and tapping forming the locking means.

[0057] Still in the case of a fixed charging socket 2, in a third embodiment of the locking means, not shown in the attached figures, the locking means consist of crimping or brazing each conductor 2b with the connection tip 3a embedded in the latter.

[0058] Referring now to Figures 13 to 14, 15a, 15b and 16 in particular, it can be seen that the fixing and connection tip 3a of each first connector 3 is connected to and secured at a connection point Cia. The connection point Cia corresponds to the bare end of a wire Cl of the charging cable Cl, which has a movable charging plug 2 (not shown) at its other end. Referring more specifically to Figures 13, 15a and 15b, it can be seen that the fixing and connection tip 3a of each first connector 3 may have a ferrule shape that can be crimped onto the terminal end of the wire Cl in question.

[0059] In a preferred embodiment of each male connection tip 3b, 4b of the first or second connector 3, 4, as can be seen in Figures 1, 3, 6, 7, 9, 16, each male connection tip 3b, 4b may comprise an elongated and rigid body 3c, 4c and an external elastic metallic sheath 3d, 4d surrounding said body 3c, 4c so as to ensure an electrical connection and a tight fit of the mutual interlocking of the male and female connection tips 3b, 4b of each connection interface 3, 4. Such a male connection tip 3b, 4b may be made from a plug called a "banana plug" which constitutes a well-known quick electrical connection element in the field of electrical connections / connections.

[0060] Preferably, the connection and fixing tip 4a of each second conductor 4 can be fixed to the electronic board 1 by brazing.

[0061] As can be seen in Figures 1, 2, 7, 8, 14 and 16, the second conductors 4 They may have an elongated shape, preferably a generally cylindrical shape. They may extend perpendicularly to the plane of the electronic board 1.

[0062] The present invention also relates to an electric vehicle charging station as described above, that is to say, it essentially comprises:

[0063] - a housing B delimiting an internal space Bl,

[0064] - at least one electronic card 1 fixed in the internal space Bl,

[0065] - at least one charging socket 2 dedicated to charging the storage battery of an electric vehicle. The charging socket or sockets 2 are either fixed by being attached to the box B, or mobile by being connected to the end of a charging cable C coming out of the box B.

[0066] Each fixed or mobile charging socket 2 comprises power and / or communication output pins 2a and conductors 2b, each connected to one of these pins. The other end of the charging cable C terminates in connection points Cia, each connected to one of the conductors 2b of the mobile charging socket 2.

[0067] The conductors 2b of the fixed charging socket 2 (or of one of the fixed charging sockets 2 in the case of a plurality of charging sockets 2) or the connection points Cia of the charging cable C (or of one of the charging cables C in the case of a plurality of charging cables C) are connected in the internal space Bl to the electronic card 1 (or to one of the electronic cards 1 in the case of a plurality of electronic cards 1) by means of a connection device.

[0068] It is understood that such a terminal can include several connection devices in the case of a plurality of 2 fixed or mobile charging sockets.

[0069] According to the present invention, in such a charging station B, the connection device consists of a connection device according to the present invention as described above and of which the fixing and connection tip 3a of each first connector 3 is connected and secured to the conductor 2b or connection point Cia concerned and the fixing and connection tip 4a of each second connector 4 is connected and secured to the electronic board 1, the male or female connection tip 4b of each second connector 4 being connected to the male or female connection tip 3b of the first connector 3 by mutual interlocking of said connection tips 3b, 4b.

[0070] It is understood that in the case of a plurality of electronic cards 1, the fixing and connection tip 4a of each second connector 4 is connected and secured to one of the electronic card(s) 1.

[0071] Thus, such a quick-connect device according to the present invention, and such a terminal equipped with such a quick-connect device, allows in particular to The installer or assembler (individual or assembly robot), on-site or in the factory, can make a quick connection in the charging station B, i.e., in the internal space B1 of its housing, between the electronics (the electronic board(s) 1) and the charging socket 2, without using any special tools or connecting cables. Such a connection device offers the manufacturer and / or the installer / assembler and / or the individual user the following advantages:

[0072] - a time saving in production (less labor),

[0075] - a reduction in risk during installation (no incorrect wiring),

[0076] - easier handling,

[0077] - simpler spare parts.

[0078] Of course, the invention is not limited to the embodiment described and shown in the accompanying drawings.
