[0001] The invention relates to a device for handling an electrical energy storage system, an electric battery equipped with said device, a vehicle intended to house said battery, and an assembly of said vehicle and said battery. It is particularly intended for electrically powered vehicles.

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

[0003] It is also known to equip electric vehicles with numerous battery cells. However, this results in an increase in vehicle weight, contrary to the intended objective.

[0004] It is also known that a vehicle battery can be changed to a fully charged one. However, the devices known for this purpose are not entirely satisfactory. Indeed, to achieve good autonomy, batteries tend to be relatively heavy and bulky. They are therefore difficult to handle.

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

[0025] As illustrated in [Fig.1], the invention relates to a device for handling an electrical energy storage system for an electric motorization of a motor vehicle.

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

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

[0028] Preferably, said housing 2 is further configured to be housed in a charging station of said electrical energy storage system. The 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, manually and / or by said robotic arm.

[0029] To facilitate these operations, said housing 2 includes bearing elements 4 designed to cooperate with said housing during said insertion and removal movements. Thanks to their rolling capacity, said bearing elements 4 limit the contact areas and friction between the housing and the housing 2.

[0030] Said housing 2 comprises, for example, a shell-shaped body 6 within which said storage system is located. Said shell 6 is made mobile by means of said bearing members 4. Said shell 6 is, for example, made of a metallic material, in particular to provide 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 two large opposing parallel faces 10a, 10b and lateral faces 10c-10f connecting said large faces 10a, 10b. In use, said large faces 10a, 10b form respectively a lower face and a upper face of said housing 2. A first 10c of said lateral faces forms a face, called the front face, by which said housing 2 is intended to be inserted into said housing. A second 10d of said lateral faces, opposite the front face 10c, forms a face, called the rear face, by which said housing 2 is intended to be removed 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 has a height corresponding to the distance separating said large faces 10a, 10b, and a length and width corresponding to the length and width of said large faces 10a, 10b. The length of said shell 4 is therefore much greater than its width and even greater than its height. In other words, said front and rear faces 10c, lOd, are smaller than said side faces 10e, lOf, and even smaller than said large faces 10a, 10b.

[0033] Said bearing members 4 are preferably configured to allow displacement of said housing 2 in a translational movement along a direction of movement, denoted X. Said bearing members 4 are further advantageously configured to allow 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 exhibit a certain lateral offset and / or a certain angle with respect to said direction of movement X, at least temporarily during said installation and removal movements. This configuration facilitates the consideration and / or correction of any misalignment of housing 2 in the housing during its handling.

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

[0035] Said housing 2 advantageously includes a handling handle 14. Said handle is located, for example, on the rear face lOd, particularly in the upper part. Said handle 14 includes a gripping area 16, intended to be grasped by the user and / or said robotic arm during handling of the housing 2. Said handle 14 extends at least partially into a notch 15 formed in said rear face lOd.

[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 includes, for example, one or more electrical connectors 18 to said terminal. The electrical connector(s) 18 are here located at 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 vehicle height dimension serving as a reference for the risk of water entering the vehicle in the event of crossing flooded areas.

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

[0038] As can be seen more clearly in [Fig.2], according to the illustrated embodiment, said rolling members 4 are located along longitudinal stops 12 of said lower face 10a.

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

[0040] Figure 3 shows an example of an embodiment of a housing 40 intended to accommodate the battery or batteries according to the invention. As a reminder, said battery 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 includes, 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 boxes 2.

[0042] Preferably, said housing comprises guide elements 42 for guiding said housing(s) 2 within said housing during the insertion and removal movements of said housing(s) 2. Said guide elements 42 are further advantageously configured to wedge, particularly laterally, said housing(s) 2 within said housing in the end-of-travel position. Said guide elements 42 here comprise angle brackets 44. Said angle brackets 44 have, for example, an L-shape. A first 44a of the arms of the L forms a raceway for the rolling elements 4. Another 44b of the arms of the L allows guidance of said housing 2 along said direction of movement X.

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

[0044] A battery according to the invention is used, for example, as follows. Once fully or partially discharged, the battery is intended to be removed from the vehicle and placed in a charging station where it will be recharged. This charging station may include other identical batteries equipped with pre-charged storage systems. According to a first possibility, if the vehicle requires it, one or more of these batteries can then be installed in the vehicle in place of the battery or batteries that have just been removed. According to another possibility, if the vehicle does not immediately require additional power, it can leave while the compartment remains empty, and one or more batteries according to the invention, from another charging station, or from the same one, will be installed when the time comes.

[0045] Referring to [Fig. 4], we observe a vehicle equipped with said housing, designated 30. Preferably, the battery or batteries according to the invention, designated 32, are not only removable but also constitute additional batteries. Thus, said vehicle further comprises at least one electrical energy storage system 34, referred to as fixed, permanently installed in said vehicle. In other words, unlike the additional batteries 32, which are removable from the vehicle, said fixed electrical energy storage system 34 is linked to the vehicle and is not intended to be removed from it.

[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 range, the vehicle accommodates either none or one in said compartment 30. either two additional batteries 32. The said housing includes here for this purpose two said boxes 40.

[0047] When no additional battery 32 is installed, the vehicle's current reserve corresponds to that of the fixed electrical energy storage system 34. The latter is sized for everyday journeys, for example, of less than 200 km. This fixed energy storage system 34 has an energy reserve exceeding 30 kWh. This reserve is, for example, between 30 and 40 kWh. It is advantageously approximately 33 kWh. It should be noted that limiting the range of this fixed electrical energy storage system 34 makes it possible to limit its weight and thus advantageously limits the vehicle's energy consumption.

[0048] When the vehicle needs to travel longer distances, it is then equipped with one or more of said additional batteries 32. Each of said additional batteries 32 has an electrical energy reserve of 10 to 30 kWh, in particular of approximately 22 kWh. If the vehicle is equipped with two said batteries having such power, it can then travel for approximately two additional hours, particularly on the motorway.

[0049] Such a duration generally corresponds to the recommended break times during long journeys. These breaks will advantageously be taken at locations where charging stations are available so that a new set of additional batteries can be installed during the break. The overall journey time will thus be unaffected or only minimally affected.

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

[0052] It should be noted that such an orientation and / or position of the battery or batteries according to the invention also applies, alternatively, 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 or batteries 32 as current sources for its motorization.

[0053] In the following figures, we observe different stages of removal and placement of the or one of said batteries according to the invention in the housing 30. Said battery is also identified as 32. However, in the same way as mentioned in the preceding paragraph, it is both an additional battery and 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 said housing 30, more particularly of said box 40 corresponding to said battery 32. More generally, the said electrical connector(s) 18 of said housing 2 are configured to allow an electrical connection to the said connection terminal(s) 60 in a limit switch position of said housing 2 in 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 includes opening / closing mechanisms 64 for said housing for charging / discharging said battery 32. Said opening / closing mechanisms 64 are articulated, in particular, on a chassis 66 of said vehicle.

[0056] Said opening / closing devices 64 include, for example, an opening / closing partition 68 for 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] The opening / closing partition 68 is preferably intended to wedge, particularly longitudinally, the housing 2 in the recess 30 in the end-of-travel position, in a closed configuration of the partition 68. To reinforce such wedgeping, the recess 30, in particular the box(es) 40, may optionally be fitted with foam blocks 70 at a longitudinal end of the recess 30 opposite the first end. Alternatively or additionally, such foam blocks 70 are provided at the level of the 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 housing 2 when the partition 68 is closed. Said foam blocks are located, for example, opposite the retaining shapes 20, in the end-of-travel position of said housing 2.

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

[0061] The vehicle further comprises a loading / unloading platform 76, extending in a substantially horizontal direction to form a charge re-entry zone during the insertion and removal of the battery 32. The loading / unloading platform 76 is configured such that two of the rolling elements 6, following one another along the direction of travel X, are simultaneously in contact with the loading / unloading platform. The loading / unloading platform 76 may also contribute to guiding the battery, in particular through its shape.

[0062] The vehicle herein further includes a crossmember 78, intended to support a bumper assembly 80, made movable. The bumper assembly 80 includes, for example, a crossmember support 82, a rear crossmember 84, a shock absorber 86 and / or the said trim piece 74. The crossmember support 82, the said rear crossmember 84, the said shock absorber 86 and / or the said trim piece 74 are stacked one on top of the other in that order, in a stacking direction corresponding to the said direction of movement X when the housing 30 is closed.

[0063] The crossmember 78 is movable, particularly in rotation, relative to the chassis 66, between a first configuration in which the bumper assembly 80 prevents loading / unloading and a second configuration allowing such loading / unloading. In the first configuration, the crossmember 78 bears against a distal end 88 of one or more rear side members 90 of the vehicle. The crossmember 78 is hinged at a lower edge 92 of the distal end 88. The vehicle may also include a stop 100 to limit the angular movement of the crossmember 78 in the second configuration. The angular stop is located near the lower edge 92.

[0064] The said opening / closing devices here include an actuator 94 allowing an opening / closing of said partition 68. This is, for example, a jack, linked at one end 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 further include a transmission member 96 configured so that an opening of said partition 68 causes said transom door 78 to move from the first configuration to the second configuration and / or vice versa in the event of closure 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 transom door 78 from one configuration to the other. Said transmission member 96 includes a rigid bar, articulated at one end to said opening / closing partition 68 and at the other end to said transom door 78.

[0066] The vehicle herein also includes a flexible sheet 102 connecting the bumper assembly 80 and a lower panel 104 of the vehicle. The flexible sheet 102 is designed to deform when the crossmember 78 is moved from one configuration to the other. In particular, the flexible sheet 102 is designed to be taut in the first configuration in order to limit aerodynamic drag of the vehicle.

[0067] In [Fig. 5], the vehicle is stationary and near the charging station, shown partially and designated 50. The compartment 30 is empty, and the battery 32 according to the invention has begun to be inserted into said compartment 30, in particular said corresponding box 40, along said direction of movement X, from right to left in the figure. Said battery 32 is still partially in the charging station, designated 50, in which it was stored. The partition 68 is open. Said cross door 78 is in the second configuration allowing removal and / or charging of the battery 32 while bearing against said stop 100 (see [Fig. 9]).

[0068] In [Fig. 6], a robotic arm, labeled 52, of said charging station 50 pushed the battery 32 along said direction of movement X towards the compartment 30 into which said battery 32 is now partially inserted. It can be seen that two of said adjacent bearing elements 4 are in contact with said loading / recharging platform 76. The other bearing elements 4 are already in contact with a lower wall 36 of said compartment 30, more particularly of said housing 40 corresponding to said battery 32.

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

[0070] At [Fig.8], with the battery 32 still in its end-of-travel position in its housing 40, the partition 68 is being closed, under the action of the actuator 94, and the cross member 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 a further rotation along the arrows 110, the partition 68 now closes the housing 30, in particular the box 40. The foam blocks 70 are compressed and longitudinally wedge the housing 2, while the angle brackets, not visible in this figure, wedge it laterally. The foam block 70 located at the level of the partition 68 also contributes to a good seal of the closure of the box 40.

[0072] Said cross member door 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 remainder of an external wall of the vehicle bumper 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] For the removal of said battery 32, the operations are carried out in the reverse order to that described above.
