Description
DESCRIPTION TITLE: MOBILE BOX WITH DOUBLE-SIDED PRIMARY CIRCUIT FOR RECHARGING A VEHICLE BATTERY The present invention claims priority from French application No. 2212043 filed on 18.11.2022, the content of which (text, drawings and claims) is incorporated herein by reference. Technical field of the invention
[0001] The invention relates to the induction charging of batteries of parked vehicles, for example in parking spaces. State of the art
[0002] Some parking areas, such as garages or car parks (public or private), include at least one parking space (or parking area), allowing a vehicle to park temporarily, and at least one charging system comprising a control and power supply base and at least one so-called "autonomous" mobile box coupled to this base via a power cable.
[0003] The mobile unit is said to be autonomous because it comprises means of movement responsible for moving it (and therefore moving it) autonomously on a rolling surface by analyzing environmental data (possibly images) acquired by at least one on-board sensor. This movement is controlled internally by an on-board computer, and intended to allow the mobile unit to go from an initial location (such as, for example, a storage location located next to the base) to a final location located under a parked vehicle.
[0004] This mobile box being responsible for recharging the battery of a vehicle, it includes a primary circuit comprising a coil primary coil capable of transforming the current coming from the base via the power cable into electrical energy, and transferring this electrical energy by induction to a secondary coil forming part of a secondary circuit fitted to a parked vehicle. This secondary coil is then responsible for transforming the transferred electrical energy into charging current for the battery of this vehicle.
[0005] For the transfer of electrical energy by induction to be optimal, the primary circuit of the mobile box must be placed just below the secondary circuit of the vehicle, but also the vertical distance between the primary and secondary circuits (or air gap) must be small. For the second condition to be satisfied, the mobile box must be able to vary the vertical position of its primary circuit because the ground clearance often varies from one vehicle to another.
[0006] Generally, this variation is obtained by means of a lifting mechanism, for example scissors, comprising a first end fixedly secured to the mobile body of the mobile housing and a second end to which the support of the primary circuit is fixedly secured. This solution is useful as long as the mobile housing can be positioned under the vehicle, and more precisely under its secondary circuit. But, when the ground clearance of the vehicle is less than the vertical extension of the mobile housing when its lifting mechanism is in the folded position, the mobile housing can no longer be positioned under the vehicle, and therefore the latter's battery cannot be recharged. Similarly, in the presence of an obstacle located under the secondary circuit of the vehicle, the latter's battery cannot be recharged.
[0007] The invention therefore aims in particular to improve the situation. Presentation of the invention
[0008] For this purpose, it proposes in particular a mobile box, on the one hand, capable of moving to a secondary circuit which equips a vehicle and is capable of transforming transferred electrical energy in recharging current for a vehicle battery, and, on the other hand, comprising a first support to which is fixedly attached a primary circuit capable of transferring electrical energy by induction to the secondary circuit.
[0009] This mobile case is characterized by the fact that:
[0010] - that its primary circuit is secured to the first support by having first and second opposite faces, visible and suitable for transferring electrical energy, and
[0011] - that it comprises a first mechanism capable of rotating the first support between first and second angularly separated positions and in which one of the first and second faces is used to transfer electrical energy.
[0012] Thus, when the ground clearance of the vehicle is insufficient to allow the mobile unit to pass under it and / or when access to the area located under the secondary circuit of the vehicle is impossible, the mobile unit stops near the vehicle (and not underneath) and deploys its primary circuit into its second position in order to pass its second face under the vehicle and position it under the secondary circuit.
[0013] The mobile housing according to the invention may include other characteristics which may be taken separately or in combination, and in particular:
[0014] - in the first position the first face can be oriented upwards to transfer electrical energy to a secondary circuit which is placed above it, and in the second position the second face can be oriented upwards to transfer electrical energy to a secondary circuit which is placed above it;
[0015] - it may comprise a second support to which the first mechanism is secured and relative to which the first support is driven in rotation;
[0016] - in the presence of the last option and in one embodiment, the first mechanism may comprise a motorized pivot connection, secured to the second support and to rigid connections to which the first support is fixedly secured, and capable of driving the rigid connections in rotation over an angular sector of 180° so as to move the first support between the first position in which it is placed at a first level situated above the second support and the second position in which it is placed at a second level lower than the first level;
[0017] - in the presence of the last sub-option, the first and second levels can be spaced in a vertical direction by a height which is equal to a sum of a vertical extension of the rigid connections and a vertical extension of the second support;
[0018] - in the presence of the last option and in another embodiment, the first mechanism may comprise first and second motorized pivot links coupled together by two rigid links, the first pivot link being secured to the second support and capable of rotating the rigid links over a first chosen angular sector and at least equal to 180° and the second pivot link being capable of rotating the first support relative to the rigid links over a second chosen angular sector and between 1° and 90° so as to move the first support between the first position in which it is placed at a first level located just above the second support and the second position in which it is placed at a second level lower than the first level;
[0019] - in the presence of the last sub-option, the first and second levels can be spaced in a vertical direction by a height which is variable depending on the first and second angular sectors chosen;
[0020] - in the presence of the last option, it may comprise a mobile body to which a first end of a second mechanism also comprising a second end is fixedly secured opposite the first end and to which the second support is fixedly secured, and suitable for translating the second support relative to the mobile body between lower and upper vertical positions;
[0021] - in an alternative embodiment, the first mechanism may comprise a motorized pivot connection, secured to the second support and to rigid connections to which the first support is fixedly secured, and capable of driving the rigid connections in rotation over an angular sector chosen so as to move the first support between the first position in which it is placed above the second support and the second position in which it is placed perpendicular to the second support;
[0022] - the mobile body may include an automatic reel to which is attached a power cable suitable for supplying electric current from a base to the primary circuit so that it transforms it into electrical energy to be transferred by induction.
[0023] The invention also proposes a recharging system, on the one hand, intended to recharge by induction a battery of a parked vehicle, and, on the other hand, comprising a base capable of supplying an electric current, and a mobile housing of the type presented above and coupled to this base.

[0034] The invention aims in particular to propose a mobile box BM intended to be part of an SR charging system and comprising a two-sided primary circuit CP facilitating induction charging of BR batteries of V vehicles having ground clearances of different heights.
[0035] In the following, it is considered, by way of non-limiting example, that the vehicle V, whose battery BR must be recharged by induction, is of the automobile type. This is for example a car, as illustrated non-limitingly in Figure 1. But the invention is not limited to this type of vehicle. It indeed concerns any type of vehicle comprising at least one battery rechargeable by induction. Consequently, it also concerns utility vehicles, coaches (or buses), trucks, trams, construction machinery, agricultural vehicles, road machinery, and aircraft (and in particular ULMs (“Ultra Light Motorized”), drones, helicopters, and flying taxis).
[0036] Furthermore, it is considered in the following, by way of non-limiting example, that the vehicle V comprises a powertrain of the all-electric type. But the vehicle could comprise a powertrain of the plug-in hybrid type, that is to say comprising at least one thermal motor and at least one electric motor coupled to at least one rechargeable battery, or else to a fuel cell.
[0037] Figure 1 schematically shows an installation IN constituting a parking lot comprising a driving surface comprising three parking spaces EPj (j = 1 to 3). As illustrated, this installation IN is equipped with a charging system SR comprising at least one base BF and a mobile (charging) box BM, according to the invention, interconnected by an AC power cable.
[0038] It will be noted that the invention relates to any rolling surface on which a mobile housing BM of a system can move. SR charging, and including in a delimited or non-delimited manner at least one EPj parking space. It should also be noted that the driving surface can be indoor or outdoor, public or private. Consequently, the IN installation can be a covered or uncovered space, such as for example a parking lot, a garage, a charging station, a building, a factory, a heliport or an aerodrome.
[0039] In the example illustrated non-limitingly in Figure 1, the installation IN (here a parking lot) is equipped with only one SR charging system. But the installation IN could be equipped with several SR charging systems. Furthermore, in the example illustrated non-limitingly in Figure 1, the SR charging system comprises only one mobile box BM connected to its base BF via an AC power cable. But the SR charging system can comprise several (at least two) mobile boxes BM connected to its base BF via associated power cables.
[0040] Although this does not appear completely in Figures 1 to 9, a mobile housing BM, according to the invention, comprises a mobile body CM comprising movement means, a primary circuit CP, at least one sensor, and at least one computer.
[0041] The (each) sensor is responsible for acquiring environmental data around it (possibly digital images). The (each) sensor can, for example, be a digital camera, or a radar or lidar. What is important is that it is arranged in such a way as to acquire data in an acquisition zone that are representative of the environment of the mobile BM box.
[0042] The computer is responsible for determining movement commands for the means of movement, in particular according to the environment which is defined by the environmental data acquired by each sensor. The computer includes in particular analysis circuits which are responsible for analyzing the acquired environmental data in order to locate the vehicle V to be recharged or a possible obstacle (such as for example a vehicle wheel or a person's foot or an object placed on the ground) in the observed environment, as well as possibly movements of objects relative to the mobile box BM. The computer is therefore arranged in such a way as to determine commands making it possible to avoid each obstacle determined on the path going from the initial place (or position) to a recharging place of the parked vehicle V and whose battery BR must be recharged. A recharging place can be located under the vehicle V (parked) or just next to the latter (V), as will be seen later. It will be noted that this path can be determined by any technique known to those skilled in the art, and in particular as a function of information defining the recharging provided at least in part by the vehicle V.
[0043] The initial location (or position) of the mobile box BM may, for example and as illustrated non-limitingly in Figure 1, be located right next to the base BF. In this case, it constitutes a storage location (or position). But this is not obligatory.
[0044] The means of movement are arranged so as to allow the mobile box BM to move autonomously on the road surface to a recharging location located under, or near, a vehicle V that has just parked and located in its field of movement (here on the first location EP1). Its movements are made according to commands which are determined by the on-board computer.
[0045] The means of movement may comprise, for example, rotatably mounted wheels (possibly holonomic (or omnidirectional)), or tracked vehicles, and electric motors driving these wheels or tracked vehicles and, for example, powered by a battery, preferably rechargeable, of the mobile housing BM.
[0046] The primary circuit CP is responsible for transferring by induction electrical energy produced from a current which is supplied by the AC power cable (connected to the base BF).
[0047] The AC power cable is preferably coupled to an automatic reel responsible for reeling it, preferably in a controlled manner, so that it remains substantially taut during movements of the mobile housing BM. For example, this automatic reel may be part of the mobile housing BM. But it could be housed in the internal space of the base BF.
[0048] The primary circuit CP is coupled to a power source of the base BF via the AC power cable. It is responsible for recharging the rechargeable battery BR of a parked vehicle V, once the mobile box BM has positioned itself at the charging location allowing its inductive coupling to the secondary circuit CS of this vehicle V which is coupled to this (rechargeable) battery BR.
[0049] The primary circuit CP comprises a primary coil associated with a capacitor and capable of being supplied with current by the AC power cable, in order to transform this current into electrical energy and to transfer this electrical energy by induction to the secondary circuit CS of the vehicle V.
[0050] The power supply source for the BF base can be a wall box (allowing the current intensity to be varied), for example, connected to a power supply network (or mains) and responsible for the distribution of electrical energy and protection (circuit breakers, fuses, differential protection), or a power supply network (or mains).
[0051] The secondary circuit CS is installed under the vehicle V and also includes a capacitor associated with a secondary coil, which is capable of transforming the electrical energy, transferred by the primary circuit CP of the mobile box BM, into recharging current for the battery BR.
[0052] As illustrated in Figures 1 to 9, the mobile housing BM also comprises a first mechanism M1, and a first support S1 to which the primary circuit CP is fixedly secured by having first F1 and second F2 opposite and visible faces. Each of these first F1 and second F2 faces is capable of transferring by induction the electrical energy produced from the current coming from the base BF, which makes the primary circuit CP two-sided. Here, "visible" means the fact that there is no element placed in front and therefore that the transfer by induction is not limited, or the fact that there is a protection element placed in front but inducing a slight reduction in the efficiency of the transfer by induction.
[0053] For example, the first support S1 may be in the form of a frame inside which the primary circuit CP is fixedly secured, or a plate provided with a through hole inside which the primary circuit CP is installed.
[0054] As illustrated in Figures 2 to 9, the first mechanism M1 is adapted to rotate the first support S1 between first and second positions which are angularly separated and in which one of the first F1 and second F2 faces is used to transfer electrical energy.
[0055] In the first position (or folded position), illustrated in Figures 2, 4, 6 and 8, the first face F1 is used to transfer electrical energy because it is oriented towards the secondary circuit CS of the parked vehicle V. For example, in the second position (or deployed position), illustrated in Figures 3, 5, 7 and 9, the second face F2 is used to transfer electrical energy because it is oriented towards the secondary circuit CS of the parked vehicle V.
[0056] It will be understood that the first position is used when the ground clearance of vehicle V is sufficiently high to allow the mobile box BM to pass under this vehicle V, and that at the same time access to the area located under the secondary circuit CS of vehicle V is possible (absence of obstacle) for the purpose of positioning of the first face F1 of the primary circuit CP under this secondary circuit CS. On the other hand, the second position is used when the ground clearance of the vehicle V is insufficient to allow the passage of the mobile box BM under this vehicle V and / or when access to the area located under the secondary circuit CS of the vehicle V is impossible (presence of an obstacle), or when the secondary circuit CS of the vehicle V is installed on one side of this vehicle V, for example substantially vertically, or on the roof of the vehicle V.
[0057] In the presence of an obstacle, the mobile box BM stops near the vehicle V and the deployment of its primary circuit CP allows it to pass under the vehicle V and to position its second face F2 under the secondary circuit CS in order to recharge the battery BR with this second face F2.
[0058] When the secondary circuit CS is installed on one side of the vehicle V, the mobile box BM stops near the vehicle V and the deployment of its primary circuit CP makes it possible to position its first face F1 or its second face F2 opposite the secondary circuit CS in order to recharge the battery BR.
[0059] When the secondary circuit CS is installed on the roof of the vehicle V, the mobile box BM stops near the vehicle V and the deployment of its primary circuit CP allows its first face F1 to be positioned opposite the secondary circuit CS in order to recharge the battery BR.
[0060] The first and second positions can therefore be angularly separated by any value between about 10° and about 270°. In the examples illustrated without limitation, the first and second positions are angularly separated by 180°. In this case, as illustrated in Figures 2 to 9, in the first position the first face F1 can be oriented upwards to transfer the electrical energy to the secondary circuit CS which is placed above it (F1), while in the second position the second face F2 can be oriented upwards to transfer the energy electrical to the secondary circuit CS which is placed above it (F2). Here, "upward-facing" means that the face F1 or F2 is substantially parallel to the rolling surface on which the mobile housing BM rests, and therefore substantially perpendicular to the local vertical direction. Here, "vertical direction" means the direction which is perpendicular to the rolling surface.
[0061] But in an alternative embodiment, the first and second positions might not be perpendicular to the local vertical direction.
[0062] In another variant mentioned above, the first and second positions could be angularly separated by 90° (and in this case in the second position the first face F1 is also used for recharging), or by 270° (and in this case in the second position the second face F2 is used for recharging).
[0063] For example, and as illustrated non-limitingly in Figures 2 to 9, the mobile housing BM may comprise a second support S2 to which the first mechanism M1 is secured. In this case, the first support S1 is rotated by the first mechanism M1 relative to the second support S2. But it could be envisaged that the first mechanism M1 is directly coupled to the mobile body CM or to equipment that the latter (CM) comprises (such as for example a second mechanism M2 to which we will return later) without using a second intermediate support S2.
[0064] In a first exemplary embodiment, illustrated non-limitingly in Figures 2 and 3, the first mechanism M1 may comprise a single motorized pivot link LP1, secured to the first S1 and second S2 supports, and capable of rotating the first support S1 relative to the second support S2 over a chosen angular sector (for example here equal to 180°) so as to move its primary circuit CP from its first position (folded) to its second position (deployed), and vice versa. It will be noted that in this first exemplary embodiment in the first and second positions the first F1 and second F2 faces are placed substantially at the same level when the first support S1 is rotated relative to the second support S2 over an angular sector of 180°.
[0065] It should also be noted that the motorization is provided by an electric motor rotating the LP1 pivot link and powered by the possible battery embedded in the CM mobile body.
[0066] In a second exemplary embodiment, illustrated non-limitingly in Figures 4 to 7, the first mechanism M1 may also comprise a single motorized pivot link LP1, but this time secured to the second support S2 and to rigid links LR to which the first support S1 is fixedly secured. This pivot link LP1 is capable of rotating the rigid links LR over an angular sector of 180° so as to move the first support S1 between the first position in which it is placed at a first level located above the second support S2 (see Figures 4 and 6) and the second position in which it is placed at a second level lower than the first level (see Figures 5 and 7).
[0067] This second embodiment advantageously makes it possible to have a second position located at a vertical level lower than that of the first position, thus making it possible to take into account a greater diversity of ground clearances.
[0068] The difference in height between the first and second (vertical) levels depends on the arrangement of the rigid links LR, and more precisely on their extension in the vertical direction. Indeed, as illustrated in Figures 5 and 7, the first and second levels can be spaced in the vertical direction by a height which is equal to the sum of the vertical extension of the rigid links LR and the vertical extension of the second support S2.
[0069] In the example illustrated in Figures 4 and 5, the rigid links LR are perpendicular to the first support S1, and consequently their vertical extension is equal to their length. In this case, it can be provided, as illustrated non-limitingly in Figures 4 and 5, that the second support S2 comprises at least one vertical protuberance EV having a vertical extension equal to that of the rigid links LR so as to allow the first support S1 to rest on their free ends when it is in its first position (Figure 4).
[0070] In the example illustrated in Figures 6 and 7, the rigid links LR are inclined at an obtuse angle relative to the first support S1, and consequently their vertical extension is less than their length. In this case, the difference in height between the first and second levels is less than that existing in the example illustrated in Figures 4 and 5, but in its first position (Figure 6) the first support S1 is placed against the second support S2, which makes it possible to reduce the vertical size of the mobile housing BM in the first position.
[0071] In a third exemplary embodiment, illustrated non-limitingly in Figures 8 and 9, the first mechanism M1 may comprise first LP1 and second LP2 motorized pivot links coupled together by two rigid links LR. In this case, the first pivot link LP1 is secured to the second support S2 and is capable of rotating the rigid links LR over a first angular sector which is chosen and at least equal to 180°, and the second pivot link LP2 is capable of rotating the first support S1 relative to the rigid links LR over a second angular sector which is chosen and comprised between 1° and 90°.This arrangement makes it possible, in particular, to move the first support S1 between its first position in which it is placed at a first level located just above the second support S2 (figure 8) and its second position in which it is placed at a second level which is lower than the first level when the first support S1 is rotated relative to the second support S2 over an angular sector of 180° (figure 9). In addition, this arrangement makes it possible to reduce. the vertical size of the mobile housing BM in the first and second positions.
[0072] It will be noted that in this third embodiment the first and second levels can be spaced in the vertical direction by a height which is variable depending on the first and second angular sectors chosen. In other words, thanks to the first LP1 and second LP2 pivot links it is possible here to vary the vertical position of the second level.
[0073] It will be noted that in each of the examples described above, the second surface F2, when oriented towards the secondary circuit above, is lower than the first surface F1 in the same orientation.
[0074] Also for example, and as mentioned above and illustrated non-limitingly in Figures 2 to 9, the mobile body CM can also carry a second mechanism M2 comprising first and second opposite ends. This first end is fixedly secured to the mobile body CM, and the second support S2 is fixedly secured to this second end. Such a second mechanism M2 is capable of translating the second support S2 relative to the mobile body CM between lower and upper vertical positions. This not only makes it possible to take into account a greater diversity of ground clearances, but also to precisely define the vertical distance between the primary CP and secondary CS circuits so as to optimize the induction transfer of electrical energy during recharging.
[0075] Also for example, and as illustrated non-limitingly in Figures 2 to 9, the second mechanism M2 may be a scissor lift. Here, a double scissor lift has been schematically illustrated. But the number of scissors of the lift M2 may take any value greater than or equal to one. In alternative embodiments not illustrated, the second mechanism M2 could include a small jack or be of the telescopic type, for example.
