    The same elements have been designated with the same references in the various figures. For the sake of clarity, only the elements that are useful for understanding the described embodiments have been shown and will be detailed. In particular, the management of the recharging of a vehicle battery has not been detailed, the embodiments described being compatible with the usual solutions.

    This description refers to an example of application to the storage of an electric cable for charging an electric vehicle. However, the embodiments that will be described apply more generally to the storage of any electrical cable, or any cable or pipe-type windable element (for example a garden hose or compressed air, a wire rope traction, etc.) for which similar problems arise.
    Among the constraints generated by the application to the charging of an electric vehicle, we note: a long cable length, that is to say a length of up to ten meters, which generates a significant weight for the cable, which usually poses a problem for the user; a desire to recharge said fast, that is to say with a current of several tens of amperes, requiring a section of conductors of several millimeters square (typically of the order of 6 mm), participating in increasing the weight cable; a need to store the cable in such a way that it does not become entangled in order to facilitate subsequent uses; a need for a compact system.
    FIG. 1 very schematically shows an embodiment of an electrical connection system for charging a battery of a motor vehicle and such a vehicle, cable deployed.
    An electric or hybrid vehicle 1 comprises one or more batteries 12 intended to supply the energy necessary for its propulsion. These batteries 12 are connected to one or more load management and control devices (chargers) 14 for controlling the charging of the batteries when they are connected to an electricity supply installation 3. The installation 3 may be a public charging station of the service station type, a domestic installation (for example at the vehicle user's residence), etc. The installation 3 is equipped with an electrical plug 32 for receiving a connection plug 52 fitted to the end of an electric cable deployed from the vehicle 1. The storage of the cable in the vehicle is carried out in bulk in a dedicated safe or using a device 7 cable reel. The installation 3 may also be equipped with an electrical connection system (not shown) consisting of a similar device for storing an installation-side cable 3 that can be unwound in order to be connected to the charger 14.
    Assuming the cable on the vehicle side, when charging the vehicle 1, the cable 5 is stretched out at least partially of the device 7. Between refills, the cable 5 is stored in the device 7.
    FIG. 2 is a schematic and functional view of an embodiment of the device 7 for storing the cable 5.
    In this embodiment, the device 7 comprises: two plates 71 and 72, movable in translation coplanar with respect to each other; and guiding elements 73 arranged approximately in several (at least two) concentric semicircles 711, 712, and 713, etc., respectively 721, 722 and 723, etc., for guiding the cable on each plate 71 and 72.
    The cable 5 is wound flat from a fixed first end 54 located approximately in the middle between the two plates 71 and 72, until its free end 56 carrying the plug 52. Starting from the end 54, the cable 5 passes successively around the guide elements by traversing the internal semicircle 711 of the first plate 71, the internal semicircle 721 of the second plate, the successive semicircles of increasing radii, to the outer semicircle 713 of the first plate and finally the outer semi-circle 723 of the second plate. The end 54 is connected for example to the loader 14 by a section 56 (Figure 1). In a variant, the end 54 carries a plug for connection to the charger 14 or to the connection section to the charger 14.
    Preferably, the device 7 further comprises at least one elastic return element (in the example of Figure 2, two pneumatic cylinders 74) to a position in which the plates 71 and 72 are spaced from one another . In the example of FIG. 2, the two jacks 74 are fixed by their bodies 742 to one of the plates 72 and by their rod 744 to the other plate 71.
    Alternatively, a spacer spring trays are used relative to each other.
    According to an exemplary embodiment in which the device is placed approximately horizontally, that is to say that the planes of the trays 71 and 72 are approximately horizontal, the two trays 71 and 72 are movable in translation one towards the other.
    According to another exemplary embodiment, applied in the case where the device 7 is in a vertical or inclined (non-horizontal) position, the plate (for example 72) situated at the top is fixed and comprises the cable exit (the free end 52 ) and the other tray (for example 71) located at the bottom is movable in translation. In this case, the weight of the cable and the low platform may be sufficient to return the cable to the wound position. If necessary, it is possible to ballast the low platform to facilitate the return to the remote position of the trays.
    According to an alternative embodiment, the number of semicircles is different from one unit of a plateau relative to the other, the entrance and the cable exit then being on the side of the plateau having the greatest number of paths. guiding the cable.
    Figures 3A and 3B are schematic views from above (assuming a horizontal device 7) showing an example of device 7, respectively in the stored cable position (or wound) and cable deployed.
    The trays 71 and 72 are movable in translation towards one another between a position (FIG. 3B) where they are spaced apart as far as possible and where the cable 5 is stored and a position (FIG. 3A) in which they are brought closer together. from the other to the maximum and where the cable is fully deployed. Depending on the amount of cable required to connect the vehicle 1 to the installation 3 (Figure 1), the trays 71 and 72 can take any intermediate position between the extreme positions of Figures 3A and 3B.
    When the cable 5 is deployed, the elastic return element, in this example a spring 74 'spacer, is armed by the traction operated by the user on the end 56 (the plug 52) of the cable to deploy . When the traction on the cable 5 is released, the spring 74 'recalls the plates towards their spaced position, which contributes to the storage of the cable 5.
    If necessary, the cable outlet, free end side, is equipped with a brake to prevent rewinding too abrupt. Similarly, the device 7 may include a cable locking system in the deployed position to avoid traction on it during charging.
    Figure 4 is a schematic sectional view along the line IV of Figure 3B. In Figure 4, there is also shown a housing 76 in which is housed the entire device. This housing may be a component integrated in the vehicle in which the device 7 is housed (for example, a rear shelf luggage cover, the bonnet, the tailgate, etc.). The housing then comprises a light 78 output cable 5.
    As illustrated in FIG. 4, depending on the restoring force of the elastic return elements, the cable can, by its weight, fall between the two plates 71 and 72. This is however not a problem insofar as, without superposition of the cable, there is no risk that the cable gets entangled.
    FIGS. 5A, 5B and 5C are top views illustrating variants of guideways of the cable in a storage device 7. In all these figures, a spring-like return element 74 'is taken as an example.
    In the embodiment of FIG. 5A, concentric slideways 73 'are provided for defining the paths guiding the cable 5.
    The embodiment of FIG. 5B corresponds to the use of pulleys 73 as in FIG. 2. The pulleys 73 have axes perpendicular to the planes of the plates 71 and 72.
    The embodiment of Figure 5C provides roller paths 73 "closer together from the embodiment of Figure 5B.
    Preferably, the rollers 73 "or pulleys 73 are rotatably mounted according to their respective vertical axes in order to facilitate deployment and storage of the cable.
    Moreover, as illustrated in FIG. 2, the pulleys 73 are preferably diabolo-shaped so as to include a groove 732 for guiding the cable.
    Depending on the length of the desired cable, several superimposed layers may be provided, each consisting of two plates and guide elements. In this case, the cable output of one level corresponds to the fixed input of the next level, etc.
    FIG. 6 represents a variant in which, in order to prevent the cable tending to fall towards the bottom of the box as in FIG. 4, the device comprises, in addition to the two plates 71 and 72 sliding towards each other and carrying the guide elements 73, a third continuous plate 79 on which the cable rests. The plate 79 then comprises lumens 792 in radial directions of the concentric (virtual) circles of the guideways in order to allow the pulleys 73 to move during the rectilinear translation of the plates 71 and 72 relative to each other.
    An advantage of the embodiments described is that the bulk of the cable reel is particularly small. Compared to winder-type systems in which the cable turns are superimposed, here a flat device is provided, particularly suitable for integration into a vehicle horizontally (in the floor, under the hood, the tailgate, etc.). ) or vertically (in a wing, a door, etc.). Compared with pulley-based devices of the prior art, the described embodiments have the advantage of minimizing the space lost between round trips or loops of the cable.
    Another advantage is that, thanks to the fixed end of the cable, it avoids the need for sliding or rotating contacts at the fixed end of the cable (charging station side). Indeed, with a rotating system, the cable is twisted and eventually break if it does not provide rotating contacts. Such contacts increase the complexity, the risks of failure and the cost. Here, the translation movement that allows a fixed end for the cable does not require any rotating or sliding contact.
    Another advantage is a reduction in the heating of the cable when it is partially unrolled. Indeed, with conventional winders in which cable turns are superimposed, it is generally forced to unroll the entire cable to reduce the heating. The wire feed device described avoids mechanical contact between the turns of the cable. Thus, one can deomais charge the battery with full power, including with a partially unwound cable.
    Various embodiments have been described. Various variations and modifications will be apparent to those skilled in the art. In particular, the practical implementation of the embodiments that have been described is within the abilities of those skilled in the art from the functional indications given above.
