Description

Title of the invention: Device for handling an electrical energy storage system, electric battery equipped with said device, electrically powered vehicle intended to accommodate said battery and assembly of said vehicle and said battery

[0001] The invention relates to a device for handling an electrical energy storage system, an electric battery provided with said device, a vehicle intended to accommodate said battery and an assembly comprising said vehicle and said battery. It is in particular intended for electrically powered vehicles.

[0002] In this field, a constant objective is to increase the autonomy of vehicles. Many solutions have been proposed, such as limiting the electrical consumption of the vehicle's components or recharging the batteries using different strategies. However, these solutions have limitations in terms of driving comfort and / or recharging time.

[0003] It is also known to equip electrically powered vehicles with numerous battery cells. However, they cause the vehicle to become heavier, which is contrary to the desired objective.

[0004] It is still known that a vehicle battery can be changed in order to install a fully charged battery. However, the devices known for this purpose are not entirely satisfactory. Indeed, to have good autonomy, batteries are likely to be relatively heavy objects and present a certain bulk. They are therefore difficult to handle.

[0005] As a result, most current exchange solutions require lifting and / or wedging the vehicle. These solutions require vehicle handling devices that are impractical.

[0024] [Fig.9] repeats [Fig.5] according to a fifth stage of implementation.

[0025] As illustrated in [Fig.l], the invention relates to a device for handling an electrical energy storage system for an electric motor of a motor vehicle.

[0026] Said device comprises a housing 2 intended to accommodate said storage system. The latter comprises, for example, a plurality of electrical energy storage cells, connected in series and / or in parallel and forming a battery of accumulators. In the illustrated embodiment, said storage system is entirely located inside said housing and is not visible. In the following, the assembly formed by the handling device according to the invention and the electrical energy storage system accommodated in said housing 2 is called a battery.

[0027] Said housing 2 is configured to be installed and removed from a housing of the vehicle according to installation and removal movements, said movements being manual and / or operated using a robotic arm.

[0028] Preferably, said housing 2 is further configured to be accommodated in a charging station of said electrical energy storage system. Said charging station is fixed, that is to say, external to the vehicle. Said housing 2 is further configured to be transferred between said housing and said charging station, ma- manually and / or by said robotic arm.

[0029] In order to facilitate these manipulations, said housing 2 comprises rolling members 4 intended to cooperate with said housing during said positioning and removal movements. Thanks to their rolling capacity, said rolling members 4 make it possible to limit the contact zones as well as the friction between the housing and the housing 2.

[0030] Said housing 2 comprises for example a body 6 in the form of a shell inside which said storage system is located. Said shell 6 is made mobile thanks to said rolling members 4. Said shell 6 is, for example, formed of a metallic material, in particular in order to have good impact resistance. The use of other materials is also possible while remaining within the scope of the invention.

[0031] Said housing 2, in particular said shell 4, has, for example, a substantially parallelepiped shape with here two large opposite parallel faces 10a, 10b and lateral faces 10c-f connecting said large faces 10a, 10b. In use, said large faces 10a, 10b respectively form a lower face and an upper face of said housing 2. A first 10c of said lateral faces forms a face, called a front face, by which said housing 2 is intended to be introduced into said housing. A second 10d of said lateral faces, opposite the front face 10c, forms a face, called a rear face, by which said housing 2 is intended to be extracted from said housing. The other lateral faces 10e, 10f form side faces of said housing 2.

[0032] Said housing 2 has a flat, or even elongated, configuration. More precisely, said shell 4 having a height corresponding to a distance separating said large faces 10a, 10b as well as a length and a width corresponding to a length and a width of said large faces 10a, 10b, the length of said shell 4 is then much greater than its width and even more than its height. In other words, said front and rear faces 10c, 10d, are smaller than said side faces 10e, 10f and even smaller than said large faces 10a, 10b.

[0033] Said rolling members 4 are preferably configured to allow a displacement of said housing 2 according to a translational movement along a direction of movement, referenced X. Said rolling members 4 are further advantageously configured to allow a movement of said housing 4 in at least one transverse direction, in particular orthogonal, to said direction of movement X, thereby allowing said housing 2 to have a certain lateral offset and / or a certain angle relative to said direction of movement X, at least temporarily during said positioning and removal movements. Such a configuration facilitates taking into account and / or correcting any misalignment of the housing 2 in the housing during its handling.

[0034] For this purpose, here, said rolling members 4 comprise rolling balls 6. Said rolling members 4 further optionally comprise rolling cages 8, fixed to said shell 6, inside which said rolling balls 8 are free to rotate in all directions of space. Said rolling members 4 are arranged, for example, at the level of the lower face 10a.

[0035] Said housing 2 advantageously comprises a handling handle 14. Said handle is located, for example, at the rear face 10d, in particular in the upper part. Said handle 14 comprises a gripping zone 16, intended to be grasped by the user and / or said robotic arm when handling the housing 2. Said handle 14 extends here at least partially into a notch 15 formed in said rear face 10d.

[0036] Said housing 2 is configured to allow an electrical connection of said storage system to an electrical terminal located in said housing. Said housing comprises, for example, one or more electrical connectors 18 to said terminal. Said electrical connector(s) 18 are here located at the level of the front face 10c, in particular in the lower part. Alternatively, they are located in the upper part so as to be positioned, in use, above a height rating of the vehicle serving as a reference for a risk of water being present in the vehicle in the event of crossing flooded areas.

[0037] Preferably, said housing 2 is provided with shapes 20 for holding said device in position in said housing. This is a flat located, for example, between said upper face 10b and said front face 10c. In the illustrated embodiment, such flats are also present between said upper face 10b and said rear face 10d. As a variant, in particular if the electrical connector(s) 18 are in the upper part of the front face 10c, the flat on the front face side 10c is then located between said front face 10c and said lower face 10a.

[0038] As is better seen in [Fig.2], according to the illustrated embodiment, said rolling members 4 are located along longitudinal edges 12 of said lower face 10a.

[0039] Preferably, said housing 2 has heat dissipation fins 22. Said fins 22 are here located at the level of said lower face 10a. They are, for example, made from the material of said shell 4. They extend along the length of the housing 2, between said rolling members 4.

[0040] In [Fig. 3], we see an example of an embodiment of a box 40 of the housing intended to accommodate the battery or batteries according to the invention. As a reminder, said or each of said batteries corresponds to the assembly formed by the housing 2 mentioned above and the electrical energy storage system that said housing 2 accommodates.

[0041] Said housing comprises, for example, one or more boxes 40, the or each of said boxes 40 being intended to accommodate the or one of said batteries and therefore the or one of said housings 2.

[0042] Preferably, said housing comprises members 42 for guiding the said housing(s) 2 in said housing during the movements of positioning and removal of said housing(s) 2. Said guide members 42 are further advantageously configured to wedge, in particular laterally, the said housing(s) 2 in said housing in the end-of-travel position. Said guide members 42 here comprise angles 44. Said angles 44 have, for example, an L shape. A first 44a of the branches of the L forms a rolling track for the rolling members 4. Another 44b of the branches of the L allows said housing 2 to be guided along said direction of movement X.

[0043] Said angles 44 are here provided in pairs in the or each of said boxes 40. They are located symmetrically with respect to each other along lower longitudinal edges 46 of said box 40. Each pair of angles 44 allows guidance of the battery housed in the corresponding box 40.

[0044] Use of the battery according to the invention takes place, for example, in the following manner. Once completely or partially discharged, the battery is intended to be extracted from the vehicle and positioned in a said charging station where it will be recharged. Said charging station possibly comprises other identical batteries equipped with storage systems already charged. According to a first possibility, if the vehicle needs it, one or more of these batteries can then be installed in the vehicle in place of the battery or batteries which have just been extracted. According to another possibility, if the vehicle does not immediately need additional current, it can set off again while the housing remains empty and one or more batteries according to the invention and coming from another charging station, or from the same one, will be installed when the time comes.

[0045] Referring to [Fig. 4], a vehicle is shown equipped with said housing, referenced 30. Preferably, said battery(ies) according to the invention, referenced 32, are not only removable but also form additional batteries. Thus, said vehicle further comprises at least one electrical energy storage system 34, called fixed, permanently installed in said vehicle. In other words, unlike the additional batteries 32, installed removably in the vehicle, said fixed electrical energy storage system 34 is linked to the vehicle and is not intended to be removed therefrom.

[0046] In the illustrated embodiment, the number of additional batteries 32 that can be installed in the vehicle is two. In other words, depending on the desired autonomy, the vehicle accommodates in said housing 30 either none, or one, or two said additional batteries 32. Said housing here comprises for this purpose two said boxes 40.

[0047] When no additional battery 32 is in place, the current reserve of the vehicle corresponds to that of the fixed electrical energy storage system 34. The latter is sized to carry out daily journeys, for example, less than 200 km. Said fixed energy storage system 34 has an energy reserve greater than 30 kW.h. Said reserve is, for example, between 30 and 40 kW.h. It is advantageously approximately 33 kW.h. It should be noted that limiting the autonomy of said fixed electrical energy storage system 34 makes it possible to limit its weight and thus advantageously limits the energy consumption of the vehicle.

[0048] When the vehicle has to make longer journeys, it is then equipped with one or more of said additional batteries 32. The said additional battery or batteries 32 each have an electrical energy reserve of 10 to 30 kW.h, in particular of approximately 22 kW.h. If the vehicle is equipped with two said batteries having such power, it can then make journeys of approximately two additional hours, in particular on the motorway.

[0049] Such a duration generally corresponds to that of the recommended breaks during long journeys. The breaks will advantageously be taken at places where charging stations are present in order to be able to install a new set of additional batteries during the break time. The overall journey time will thus not be affected or will be affected very little.

[0050] Said vehicle is advantageously equipped with a recharging system, not illustrated, for said fixed electrical energy storage system 34. It is intended to be used during long stops, for example during the night, by connecting the vehicle to a fixed electrical network via said on-board recharging system.

[0051] According to the illustrated embodiment, said fixed electrical energy storage system 34 extends transversely in said vehicle, that is to say, orthogonally to said direction of movement X of the housings of the additional batteries 32 and / or said additional batteries 32 extend longitudinally, that is to say parallel to said direction of movement X. Said housing 30 is located, for example, under a trunk and / or rear seats of said vehicle.

[0052] It should be noted that such an orientation and / or position of the battery(ies) according to the invention also applies, as a variant, when they are not additional batteries but one or more main batteries of the vehicle, that is to say when said vehicle does not include a fixed system 34 for storing electrical energy but only said removable battery(ies) 32 as current sources for its motorization.

[0053] In the following figures, different steps of removal and installation of the or one of said batteries according to the invention in the housing 30 are observed. Said battery is still marked 32. However, in the same way as mentioned in paragraph previous, it is as much an additional battery as a main battery.

[0054] The said electrical connection terminal(s), marked 60, of the said housing(s) 2 are here located at the bottom of the said housing 30, more particularly of the said box 40 corresponding to the said battery 32. More generally, the said electrical connector(s) 18 of the said housing 2 are configured to allow an electrical connection to the said connection terminal(s) 60 in an end-of-travel position of the said housing 2 in the said housing 30.

[0055] Said housing 30 is configured to be accessible from a rear face 62 of the vehicle. For this purpose, here, said vehicle comprises members 64 for opening / closing said housing for loading / discharging said battery 32. Said opening / closing members 64 are articulated, in particular, on a chassis 66 of said vehicle.

[0056] Said opening / closing members 64 comprise, for example, a partition 68 for opening / closing said housing 30. Said opening / closing partition 68 is advantageously configured to make said box(es) 40 liquid-tight.

[0057] It is located at a first longitudinal end of said housing 30. Said opening / closing partition 68 is here articulated, in particular in rotation, at the level of a transverse edge 72 of an opening of said housing 30.

[0058] Said opening / closing partition 68 is preferably intended to wedge, in particular longitudinally, said housing 2 in said housing 30 in the end-of-travel position, in a closed configuration of said partition 68. To reinforce such wedging, said housing 30, in particular said box(es) 40, are optionally provided with foam blocks 70 at a longitudinal end of the housing 30 opposite said first end. Alternatively or additionally, such foam blocks 70 are provided at said partition 68.

[0059] Said housing 30, in particular said box(es) 40, are configured so that said foam block(s) 70 are compressed by said casing 2 when the partition 68 is closed. Said foam blocks are located, for example, opposite the holding shapes 20, in the end-of-travel position of said casing 2.

[0060] Said opening / closing members 64 further comprise a covering piece 74, located at a bumper of the vehicle. Said partition 68 and said covering piece 74 are preferably located at a distance from each other, in said direction of movement X, in order to form a shock absorption zone thanks to the space thus left between them.

[0061] Said vehicle further comprises a loading / unloading tray 76, extending in a substantially horizontal direction in order to form a charging recovery zone during the movements of placing and removing the battery 32. Said loading / unloading tray 76 is configured so that two of said rolling members 6, following one another in the direction of movement X, are simultaneously in contact with said loading / unloading platform. Said loading / unloading platform 76 possibly participates in guiding the battery, in particular by a choice of shape given to it.

[0062] Said vehicle also comprises here a cross member holder 78, intended to support a bumper assembly 80, made mobile. Said bumper assembly 80 comprises, for example, a cross member support 82, a rear cross member 84, a shock absorber 86 and / or said trim piece 74. Said cross member support 82, said rear cross member 84, said shock absorber 86 and / or said trim piece 74 are here stacked on top of each other in this order, this according to a stacking direction corresponding to said direction of movement X when the housing 30 is closed.

[0063] Said cross member carrier 78 is movable, in particular in rotation, relative to the chassis 66, between a first configuration in which said bumper assembly 80 prevents loading / unloading and a second configuration allowing said loading / unloading. In said first configuration, said cross member carrier 78 bears against a distal end 88 of one or more rear side members 90 of said vehicle. Said cross member carrier 78 is articulated at a lower edge 92 of said distal end 88. Said vehicle also optionally comprises a stop 100 to limit an angular movement of said cross member carrier 78 in said second configuration. Said angular stop is located near said lower edge 92.

[0064] Said opening / closing members here comprise an actuator 94 allowing opening / closing of said partition 68. This is, for example, a jack, connected at one of its ends to the box 40, in particular at the level of a wall opposite said transverse edge 72, and at the other to said partition 68.

[0065] Said opening / closing members also comprise a transmission member 96 configured so that an opening of said partition 68 causes a passage of said cross-member door 78 from the first configuration to the second configuration and / or vice versa in the event of closing of said partition 68. Said transmission member 96 thus makes it possible to avoid the use of an independent actuator for the passage of the cross-member door 78 from one configuration to the other. Said transmission member 96 comprises a rigid bar, articulated at one of its ends on said opening / closing partition 68 and at the other of its ends on said cross-member door 78.

[0066] Said vehicle also comprises here a flexible web 102 connecting said bumper assembly 80 and a lower panel 104 of said vehicle. Said flexible web 102 is intended to deform when the cross member 78 passes from one configuration to the other. Said flexible web 102 is in particular intended that, in said first configuration, it is taut in order to limit an aerodynamic drag phenomenon of the vehicle.

[0067] In [Fig. 5], the vehicle is stationary and close to the charging station, partially shown and marked 50. The housing 30 is empty and the battery 32 according to the invention has started to be introduced into said housing 30, in particular said corresponding box 40, in said direction of movement X, from right to left in the figure. Said battery 32 is still partly in the charging station, marked 50, in which it was stored. The partition 68 is open. Said cross-member door 78 is in the second configuration allowing removal and / or charging of the battery 32 while being supported on said stop 100 (see [Fig. 9]).

[0068] In [Fig. 6], a robotic arm, marked 52, of said charging station 50 has pushed the battery 32 in said direction of movement X towards the housing 30 in which said battery 32 is now partially inserted. It can be seen that two of said neighboring rolling members 4 are in contact with said loading / recharging tray 76. The other rolling members 4 are here already in contact with a lower wall 36 of said housing 30, more particularly of said box 40 corresponding to said battery 32.

[0069] In [Fig.7], after having been further moved in said direction of movement X towards a bottom of the housing 30, said battery 32 is now in its end-of-travel position, at the bottom of said box 40, the partition 68 being however still open and said cross-member holder 78 is still in said second configuration. The robotic arm 52 has withdrawn into said charging station 50.

[0070] In [Fig.8], the battery 32 still being in its end-of-travel position in its box 40, the partition 68 is in the process of closing, under the action of the actuator 94, and the crosspiece holder 78 is approaching the first configuration, under the action of the transmission member 96, itself driven by said partition 68, according to the arrows, marked 110, indicating their respective rotation.

[0071] In [Fig.9], after an additional rotation according to the arrows 110, the partition 68 now closes the housing 30, in particular the box 40. Said foam blocks 70 are compressed and wedge said housing 2 longitudinally while said angles, not visible in this figure, wedge it laterally. Said foam block 70 located at the level of said partition 68 further contributes to good sealing of the closure of the box 40.

[0072] Said cross member 78 is in the first configuration. Said bumper assembly 80 is in the longitudinal extension of said rear side member 90. Said trim piece 74 is in the extension of the rest of an external wall of the bumper of the vehicle and thus conceals access to the housing 30 from the outside.

[0073] For its part, the flexible veil 102, previously folded in figures 5 to 8, is now stretched.

[0074] To remove said battery 32, the operations are carried out in the opposite direction to that explained above.
