Description

STRUCTURE FOR THE PRODUCTION AND STORAGE OF ELECTRICAL ENERGY

FIELD OF THE INVENTION The invention relates to the production of electrical energy, and more particularly to modular structures capable of adapting to several types of electrical energy source.

STATE OF THE ART

There are many different sources of electrical energy, including photovoltaic, thermoelectric and piezoelectric. Usually, a system for producing and storing electrical energy is specifically designed for a single type of power source and once the system is installed, when it is desired to change the type of source, the only solution available is usually the replacement of the system as a whole. Similarly, the simultaneous use of several sources of different types involves juxtaposing as many electrically independent systems and installing an electrical box connected to their output to process and store the energy they produce. The installer installing the systems in the field must therefore take into account the specificity of each system for their installation, thus complicating his task.

To this end, the invention relates to a modular structure for the production and storage of electrical energy, comprising at least a first production module consisting of a production panel and a power generation device housed in the production panel, and an electrical energy storage panel electrically connected to the production panel for storing electrical energy produced by the device, wherein:

the power generation device belongs to one of several different types of power generation device; the production panel includes:

at least one first connection face;

electrical conductors electrically insulated from each other, an electrical conductor being provided for each of the types of device, the device being electrically connected to the electrical conductor corresponding to its type to deliver electrical energy thereto; and

o electrical connectors, arranged on the first connection face and electrically connected respectively to the electrical conductors;

the storage panel includes:

at least one connection face each comprising electrical connectors capable of releasably cooperating with the electrical connectors disposed on the first connection face of the production panel, the connectors of the first face of the production panel cooperating with the connectors of the one of the connection faces of the storage panel; and

By "electrical conductor" is meant here a single electrical conductor, for example of the wired type and / or metallic track type, or a set of electrical conductors connected together so as to define a current path from the production device. energy housed in the production panel to at least one side of the production panel.

In other words, a power generation source is integrated in a "universal" panel capable of receiving several different types of source and having an interface comprising a connector for each source. The storage panel comprises a corresponding universal connector that allows to receive electrical energy to store without having to take any particular action in terms of connectivity concerning the type of energy sources.

The installation is thus simplified, since it is sufficient for an operator to connect a production panel to the storage panel. Replacing a source is also simplified since it involves either replacing the device in the panel or replacing the panel itself. Finally, the storage panel may have several connection faces allowing the simultaneous connection of several production panels, regardless of the sources of electrical energy they incorporate. An operator in charge of the installation of the system can therefore easily adapt to any type of request in terms of number and / or type of source without making its installation task complicated.

More particularly, connected production panels define an electrical path from each power generating device to the production panel, a specific path being provided for each type of source. There is therefore no particular treatment of the energy produced by a device before it is transferred to another production panel.

In other words, the structure is free regarding its dimensions, a panel that can be added in any direction. In addition, when the panels are articulated, it is possible to define, if necessary, polyhedra to obtain a compact structure. For example, five production panels and the storage panel can be connected to form a cube.

According to one embodiment, the electrical connectors of the first connection face of each production panel are male connectors. In addition, the electrical connectors of the second connection face of the production panel are female connectors.

In other words, it is possible to simply modify a source of energy by removing a source housed in a panel and replacing it with another source of energy, without the installer having to worry about connections. electric. According to one embodiment, at least one production panel comprises a light concentrator. Such a panel therefore makes it possible to increase the quantity of electricity produced by a device of photovoltaic or thermoelectric type.

Referring to Figure 1, an example of structure 10 for producing and storing electrical energy according to the invention comprises a panel 12 for storing electrical energy and a set of modules 14 for generating electricity. Each module 14 is mechanically attached and electrically connected to another module 14 or to the storage panel 12, so that each module 14 belongs to a chain of at least one module terminating in the storage panel 12. Each module 14 of production electricity comprises a panel 16 called "production", and a power generation device 18 housed in the panel 16, the device 18 belonging to a predefined type of electrical energy source, in particular photovoltaic (PV), thermoelectric ( TE) or piezoelectric (PZ). Referring to Figure 2, each production panel 16 has a rectangular parallelepiped frame 20 having a housing 22 for receiving a PV, TE or PZ device. The panel also comprises a hinge 24 integral in translation with a transverse face 26, or slice, of the frame 20, and defining a face or surface 28 adapted to rotate around a first axis of rotation 30 perpendicular to the wafer 26 and around a second axis of rotation 32 parallel to the wafer 26 and secant with the first axis of rotation 30, the axes 30, 32 being preferably positioned in a median plane of the wafer 26.

Advantageously, the rotations about the axes 30, 32 are each limited, for example by stops, to a predetermined stroke, advantageously to ± 90 °, around a rest position in which the face 28 is positioned in the plane defined by the axes 30, 32, which preserves the integrity of electrical conductors passing through the hinge 24. In an embodiment illustrated in Figures 2, 3 and 4, the hinge 24 comprises a part 34 having a tubular portion 36 of main axis the axis of rotation 30, extending at one of its ends by a circular flange 38 housed in a circular cavity 40 formed in the edge 26 of the frame 20, and extending to the other of its ends by an annular portion 42 open in the extension of the recess 44 of the tubular portion 36. The hinge 24 also comprises a hollow circular cylinder 46 of diameter corresponding to the annular portion 42 and received therein so as to rotate, the axis of symmetry of the cylinder 44 thus constituting the axis of rotation 32 of the hinge 24. The cylinder 44 has an opening 47 of sufficient size for a portion thereof to be in alignment with the recess 44 over the entire rotational stroke of the cylinder 44 in the annular portion 42. Finally, the cylinder 44 comprises a male electrical connector 48, 50, 52 for each predefined type of electrical energy source, ie three male connectors in the frame of PV sources, TE and TZ, and a male electrical connector 54 for the mass The male connectors 48, 50, 52, 54 are furthermore identical, aligned and arranged on an axis parallel to the axis of rotation 32 when the hinge 24 is in its rest position.

Referring more particularly to Figure 2, the frame 20 comprises, in each of its other three three slots 56, 58, 60, female electrical connectors 62, 64, 66, 68 arranged in the median plane of the wafer, number equal to the number of male connectors 48, 50, 52, 54 of the face 28, distributed identically thereto and of dimensions corresponding to those of male connectors 48, 50, 52, 54.

Referring also to the simplified view of FIG. 5, each production panel 16 comprises electrical conductors housed in the thickness of the panel 16, an electrical conductor or a set of connected electrical conductors being provided for each type of power source. electric energy. More particularly, each conductor 70, 72, 74, 76 is electrically isolated from the other conductors and electrically connects a male electrical connector 48, 50, 52, 54 of the face 28 of the panel 16 with a female electrical connector of each of the faces 56, 58, 60 of the panel 16.

As is known per se, an electricity generating device 18, for example a PV device in the example of FIG. 5, delivers the energy it produces, in particular an electric current, to two output terminals 78 , 80. According to the invention, the two output terminals 78, 80 of the device 18 are respectively electrically connected, for example by welding of two conducting wires, to the electrical conductor 70 dedicated to the ground and to the electrical conductor 72 provided for the type From source to which the device 18 belongs. Thus, each male connector and each female connector is associated with a single type of electrical source or ground. To connect to the male connectors 48, 50, 52, 54, a portion of the electrical conductors 70, 72, 74, 76, consisting of insulated sheathed conductors, passes through the recess of the workpiece 34 and extend into the internal volume of the cylinder 46 through an opening 47 thereof to connect respectively to the connectors 48, 50, 52, 54.

Preferably, the wires are held together, for example by means of a cable clamp 82 disposed in the tubular portion 36 of the part 34 so as not to hinder the rotation of the hinge of the panel 16. In addition, the wires are of sufficient length not to stretch and break during the rotation of the cylinder 46, and thus ensure electrical continuity between the male connectors and the portion of the conductors housed in the frame 20 of the panel 16. Preferably, the son are all just long enough to achieve this result in order to oppose at least the rotation of the cylinder 46. Advantageously, the opening 47 of the cylinder 46 has dimensions sufficient for a portion thereof is always facing the recess 44 of the piece 34 for any rotation of the cylinder about the axis 32.

The portion of the electrical conductors 70, 72, 74, 76 disposed in the frame 20 of the panel 16 is for example made of metal tracks, for example copper, which are welded son passing through the joint of the panel, tracks taking little space, being light, not very sensitive to vibrations and being fixed. For this purpose, the frame 20 is for example formed of two parts of insulating material, carried over one another and secured by gluing or by a system of clips, the tracks being deposited by photolithography or by a printing system in the manner of a circuit board on one of the parts before the finalization of the frame.

Referring to Figure 6, the storage panel 12 takes for example the shape of a rectangular parallelepiped and comprises at least one connection face 84, and preferably as many connecting faces as transverse faces. Each connection face comprises female electrical connectors 86, 88, 90, 92 adapted to removably cooperate with the male electrical connectors of a production panel 16. Each female connector is dedicated to a source type or ground and is electrically connected to an electrical energy storage circuit (not shown) housed in the storage panel 12. The storage circuit comprises, as is known per se, current processing circuits collected by the female connectors for storage purposes, for example rectifiers, DC DC and / or DC / AC converters, a battery, microbattery , an accumulator or others, rechargeable and powered by the processing circuits. The processing circuits can be specific to each type of energy source in order to take into account their specificity of electricity production. The processing panel also comprises one or more output connectors 94, 96, for example a socket 94 and a connector of the USB 96 type, connected to the storage circuit for supplying devices connected thereto, such as, for example autonomous sensors (battery charger, MP3 player, mobile phone, abandoned sensor, for example in home automation ...)

The installation of a structure according to the invention is therefore simply carried out. After choosing the type of source and their respective number, the corresponding devices are housed in the production panels and the geometry of the structure is chosen, for example according to the topology of the environment, or even for aesthetic purposes . The installer then mounts the structure by inserting the male connectors of one panel into the female connectors of another panel or storage panel, thereby providing the mechanical and electrical connection of the structure. All the devices of the same type are thus connected in parallel, which makes it possible to add their electric currents.

At any time, the structure can be changed in a simple way by disconnecting the male connectors from the female connectors, and by removing, replacing and / or adding one or more production modules, and / or by reorganizing the arrangement of the modules.

Thanks to the modular and articulated structure of the invention, it is possible to produce any form of polyhedron, for example a cube, by connecting production modules 14 with the storage module 12, as illustrated in the view simplified of Figure 7 where the various elements are assembled, for example flat, as shown, before being maneuvered by means of their articulation to achieve the shape of the cube.

The production panels just described are parallelepipeds rectangles substantially full, except for a portion dedicated to the joint. However, the panels can take different geometries in order to implement additional functions, advantageously specific to the source types. Similarly, it has been described a production module comprising a single device for generating electricity. A production panel may, however, accommodate more than one device, respectively connected to the corresponding electrical conductors. For example, referring to the top view and the sectional view of Figures 8 and 9, the frame 20 of a production panel 16 includes a solid and convex face 100 forming a solar concentrator. A photovoltaic device 102 is disposed on the convex face 100 and the hot face of a thermoelectric device 104 is disposed under the face 100. In this way, the face 100 recovers the heat produced by the solar radiation 106 incident on the face 100 and the PV device 102, and transfers it to the hot face of the device TE 104.

In another embodiment illustrated in the top and sectional views of FIGS. 10 and 11, the frame 20 of a production panel is pierced with through channels 108 arranged facing the cold face of a device TE 110. so as to cool it by a wind 112 engulfing the channels 108 by Venturi effect. The channels are preferably of different orientation to adapt to wind direction and / or more channel stages with different directions may be provided to accommodate a wider range of wind directions.

In other embodiments illustrated in the figures, a panel frame 20 receives and combines a plurality of electric power generating devices, in particular a PV device in contact with the hot face of a device TE (FIG. 12), at least two PV devices stacked and connected in series (Figure 13), at least two stacks of two TE devices having their cold faces in contact (Figure 14).

In general, each main face of a production module can be dedicated to a specific environment or use, the front of a module having a function different from its back.

In addition, the structure may also comprise passive panels that do not include an electricity generating device and serve to reflect, and preferably to concentrate, solar radiation towards a PV and / or TE type production module. For example, with reference to the structure 112 illustrated in FIG. 15, the structure comprises a reflective panel 114 of identical geometry to that of the production panels, and thus comprising a hinge and male and female connectors for geometry and layout. identical to those of a production panel. The panel In the embodiment illustrated in FIG. 15, the reflector 114 is oriented to reflect the solar radiation towards a PV and / or TE production module 14a.

In another embodiment of the invention illustrated in FIG. 16, a production panel comprises an individual electrical energy storage circuit 120 comprising the electronic conversion and storage circuit, the circuit diagram of the panel being modified so that the electrical conductors first pass into the storage circuit before continuing in the articulation 24. The advantage of this embodiment is thus to have several independent portable power sources for several people simultaneously for example. Thus, the user has the opportunity to use the power source of the panel directly, or the ability to connect the panel to another panel or storage panel facing the other faces. In the latter case, the energy of the panel is transferred out of the panel and not stored in the individual circuit 120.

Production panels comprising a male face and three female faces have been described. Alternatively a different number of female faces may be provided. Similarly, more than one male face can be provided. Similarly, the treatment panel may contain one or more male faces.

An electric power generating device has been described which is arranged in the frames of the production panels and soldered to the electrical conductors. Alternatively, each conductor of a production panel is connected to an electrical connector accessible from the housing of the production panel and the power generation devices comprise a complementary connector adapted to cooperate with the corresponding connector of the panel. A device can thus be inserted in the panel removably.
