Description

SOLARPLEXUS

AUTONOMOUS AND MOBILE DEVICE FOR PRODUCING, STORING AND DISTRIBUTING ELECTRICAL ENERGY The present invention relates to the field of autonomous systems for producing and storing electricity.

The invention relates more particularly to a device which is both mobile and compact, and which is capable of allowing, on the one hand, a production of electricity from solar energy, and, on the other hand, a storage of this electricity produced in - internal - storage ^- batteries ^- ^ as well as in ^- batteries .......................

portable external devices, the latter being specially designed to be the only devices capable of connecting to said device.

In particular, a device has been developed which allows both intelligent and autonomous management of electricity production and storage, so that it is available and usable in regions where access to electricity is difficult.

In - · ΌΛϊ9, ·· - · -τβ · '·· “ύΐ8ρο8ϊω can also allow, in particular, access to an electronic telecommunication network such as the Internet for a large number of users, access to a refrigerator as well management, monitoring and control of its remote operation.

Traditionally, it is known in the state of the art, autonomous systems making it possible to have access to electricity, in particular by means of mobile thermal systems, such as motors or turbines and making it possible to connect to existing electrical networks in order to quickly remedy the lack of means of electrical production.

These .wdïiBpoiSÆljiÆs. parts of developing countries.

It is also known from the state of the art of so-called “micro-networks” systems which consist in building a power plant!

_ î i

-2electric from photovoltaic or wind energy and to set up a simplified electrical network to connect the homes of the micro-grid to the power plant.

This device effectively meets the need for electricity in isolated areas but, on the other hand, it turns out to be expensive, not mobile, and time consuming to install. In addition, such a device raises many challenges as to the infrastructure to be set up while maintaining a necessary level of security.

__ ^The ___ systems ___ allowing ___ an ____ aut © consumption ................ in electricity, in other words the production and consumption of its own electricity (via solar panels on the roof of the house, for example ) are also beginning to democratize and may be an answer in remote areas.

However, these systems are difficult to apply in developing areas given the very high costs of these installations, unsuitable roofs, maintenance and operation requiring specialized support locally.

Thus, the solutions which are currently proposed in the state of the art are not suitable for areas not supplied with electricity in developing countries.

Also known, in the prior art, is the US patent application US 2004/124711, which relates to a mobile energy production system comprising a first energy production means, coupled to a mobile housing. , in which there is also a second means of energy production, different from the first, for example photovoltaic panels and a means of production from wind energy. An interface is also provided for the connection of a wide variety of rechargable devices.

However, the system proposed here has several drawbacks, and in particular said system does not make it possible to guarantee, to the users coming to recharge their device (s), an availability of electrical energy. It is therefore entirely possible for a user to move to the

-3 energy production, wait a longer or shorter time to be able to connect his device, depending on the number of users already present or waiting on site, only to be refused the loading of his or her 5 devices, to because of unavailability of electrical energy, Patent document FR 3 011 699 describes an installation capable of being electrically autonomous, and generating energy from a natural source. The installation further comprises a “hard” building, energy storage means as well as an external electricity distribution terminal, to which any type of electrical appliance can be connected, such as battery chargers. telephone, computers, etc.

One of the drawbacks of this installation is that it is non-mobile, consequently requiring heavy construction operations of a building, like other devices of the state of the art already mentioned.

In addition, and as for the aforementioned US patent application US 2004/124711, since the building constitutes the element to be supplied with electricity as a priority, the external terminal receives only a surplus of energy which may be available. Thus, here again, a user coming to recharge a portable device has no guarantee of energy availability and can potentially move and / or wait to, finally, be unable to recharge from his device.

The present invention is intended to respond to the various drawbacks of the existing one by proposing a compact, mobile device which can be delivered and installed quickly and easily in a region devoid of electricity supply, for example. This device allows electricity production and therefore access in particular to light and / or to a refrigeration system and / or to an electronic telecommunication network for the populations living near this device.

In an entirely preferred embodiment, which is that shown in FIG. 1, the means for producing electricity 2, for example in the form of a plurality of photovoltaic panels 20, rests on two containers 31, 32, positioned, preferably, parallel to each other and spaced from each other by a certain distance, for example a few meters, preferably between 5 and 7 meters ............. ..

However, such an exemplary embodiment should not be considered as limiting the invention, and the present device 1 could also include a single container 31, for example, or a number of containers greater than two, depending in particular on the needs. in energy of the area in which the device 1 is intended to be installed.

A device 1 comprising two containers 31, 32, is however particularly advantageous, because it makes it possible to deploy a support structure 4 between said two containers 31, 32, so as to have a sufficiently large surface area of photovoltaic panels 20, for a production of sufficient electricity, while ensuring optimal support for said holding and fixing structure 4 on these two containers 31, 32.

The support structure 4 and, more generally, the entire device 1, are dimensioned to withstand cyclonic winds present in the isolated areas targeted for its installation.

Said uprights 5a, 5b are advantageously positioned at the four corners of each of the containers 31, 32, as illustrated in FIG. 1 and in FIG. 4, where it is noted that the structure 4 in the form of a metal frame 41 comprises four long end posts 5a, two for container 31 and two for container_32., __ e_t _, __ de_même _, __ four — short end posts 5b.

Most preferably, each long end upright 5a is connected to its crosspieces 43 by means of at least one inclined strut 44.

The support element 3, in this case said containers 31, 32 of the device 1, in addition to their support function for the photovoltaic panels 20, can contain a certain number of elements, or components, of the device 1, as illustrated in the figure 2.

In any event, it is possible to have, in the containers 31, 32, all the equipment necessary for mounting and operating the device 1 for producing, storing and distributing electrical energy according to the invention, which necessarily leads to a reduction in the costs of transport, manufacture, and installation of said device 1.

In addition, a large majority of the equipment making up the device 1 will be factory fitted in order to facilitate installation on site and only the elements arranged outside of the support element (s) 3 will be transported inside said support elements. 3 and mounted on site.

Thus, in particular, at least one of the two containers 31, 32 contains at least one means 6 for internal storage of the electrical energy produced by said production means 2 with which said storage means 6 is electrically connected.

Preferably, said internal storage means 6 consists of a plurality of internal storage batteries 60, these allowing regulation of the photovoltaic energy produced, energy storage in the event of overproduction in relation to the 5 needs, and the restitution of this energy in the event of peaks in consumption or insufficient production by the means of producing electrical energy 2.

These internal storage batteries 60 are in particular capable of compensating for the lack of production of electrical energy by the _____ photovoltaic panels 20 during less-than-energized days and make it possible to provide the necessary electrical power during the day of use, and in the evening. , when said panels 20 no longer produce electricity.

Preferably, the operation of the internal storage batteries 60 is optimized, in the device 1 of the invention, by charge regulators 10 integrated into charger inverters connected to the production means 2 and which are associated with each of said batteries 60 The role and operation of these regulators 10 will be described in more detail below.

All the internal storage batteries 60 can be enclosed in only one of the two containers, for example the container 31 as desired to illustrate the appended FIG. 2, or even be distributed between the two containers 31, 32, according to one embodiment. different and not shown.

In addition to the internal storage batteries 60, said support element 3, preferably in the form of at least one and more preferably still of two containers 31, 32 also contains at least one inverter 7, electrically connected to the means of producing electrical energy. 2, and capable of converting the direct current produced by the photovoltaic panels 20 into an alternating current with which at least one electrical connector 8 is supplied, for example in the form of charging sockets for mobile batteries, the said (s) (s) electrical connector (s) (sJ 8 forming part of the device 1 of the invention, 35 as well as said mobile batteries.

-15In particular, the inverters 7 are equipped with a program type MPPT (Maximum Power Point Tracking) which permanently searches for the maximum power point of the photovoltaic panels 20.

As regards the mobile batteries, external to the device 1, they are not shown in the figures. However, these are intended to be entrusted to the populations living around the place where the device 1 of the invention is implanted. Said mobile batteries will thus allow a supply, in electricity, .......... of the dwellings of the non-connected zones.

Only these mobile batteries, specially adapted to the device 1 of the invention, can be connected to the electrical connector (s) 8. It is thus provided that other personal devices belonging to the users, of the telephone or portable computers, cannot be connected to said electrical connectors 8.

These external mobile batteries are, for example, portable 400 Wh batteries of Li-Ion technology, or equivalent, equipped with USB ports and preferably with a handle to facilitate the transport of said battery. In addition, these mobile batteries can be of various colors in order to facilitate their identification by their owner.

The USB ports are used to power, for example, a lighting system, for example based on LEDs ("lightemitting diode" in English or light emitting diodes). The lighting system is composed of a USB cable electrically linked to LEDs with a power, for example, of at least 15 W in total, and having the capacity to illuminate a surface of at least 50 m ² . The other USB ports fitted to the mobile battery can be used to charge small electronic devices (such as phones or laptops, tablets, etc.).

Most preferably, the mobile batteries intended to be associated with the device 1 of the invention are sized for a use defined as follows: supply of the

- 16 lighting system, mentioned above, for a period of 6 hours per day, for example, and daily recharging of two or three small portable electronic devices. A P®ut indicator can be placed on the mobile battery to indicate the percentage of charge thereof.

To return to the electrical connectors 8 to which said mobile batteries are intended to be connected, these are specially designed to charge only the mobile batteries associated with the device 1 of the invention.

1θ ____ So that only the mobile batteries forming an integral part of the device 1 of the invention can be connected to the electrical connectors, the latter can, for example but not limited to, be equipped with at least one keying device preventing any connection of electrical devices other than said external mobile batteries.

The latter can also, or alternatively, be provided with an identifier, of the barcode type, which must imperatively be recognized by an identification means with which said device 1 is equipped, so that the connector 8 to which said mobile battery is connected is supplied with electricity to allow recharging of said external mobile battery.

This particular characteristic of the device 1 of the invention, namely that it comprises a plurality of dedicated mobile batteries, thus makes it possible to avoid other or untimely use of the energy produced by said device 1, and to guarantee each user being given such a mobile battery to be able to recharge it at regular time intervals, as will be explained in more detail below.

Also, no other charge, with the exception of said mobile batteries, is allowed on the device 1 of the present invention.

Advantageously, the electrical connectors intended for recharging said external batteries are positioned on at least one of the external faces of at least one of the containers 31, 32.

Thus, for example, as shown in FIGS. 1, 2 and 3, each of the containers 31, 32 has twenty electrical connectors 8, distributed over the two longest outer faces of said containers 31, 32. In other words, each of the longest faces of each of the containers 31, 32 can be equipped with ten electrical connectors 8.

In addition to said electrical connectors 8 which, for the record, are supplied with electrical energy either via the photovoltaic panels 20, after a conversion of the continuous signal into an alternating signal by at least one inverter 7 _f __or ..... through 1 intermediary of the energy stored in the storage batteries 60 and redistributed by at least one charge regulator which is in practice integrated into an inverter, said device 1 of the invention may also include at least one additional component. This may consist, for example, of at least one refrigerator 9 and / or at least one ventilation means and / or at least electronic telecommunication means and / or at least one lighting and / or at least one means of identification, of the barcode reader type, of an external device, in this case mobile batteries.

Said refrigerator 9, access to which can be advantageously allocated only to authorized persons, preferably has a capacity of at least 0.5 m ³ and has the function of allowing, for example, the storage of medicinal products and / or vaccines and can also be used for any type of cold storage.

As regards now said electronic telecommunication means, these comprise at least one WEB server, a WIFI router and an internet router, and have the function of allowing users present near the device 1 and who come, for example , to recharge the mobile battery that has been allocated to them, to connect to the Internet (load documents, emails, etc.), and to wait during the charging time of their personal mobile battery.

Furthermore, in a particularly advantageous manner, said electronic telecommunication means are capable of allowing, on the one hand, the remote and real-time transfer of various data relating to the operation of the device 1, such as the production of electrical energy, the state of charge of the internal storage batteries and, on the other hand, a dialogue and a remote control of the device by specialists.

This brings additional security to the operator and users of the device 1 since there is a permanent analysis of the vitality of the various_electrical_electrical, electronic and computer systems. The verification of compliance with the operating range of this equipment makes it possible to anticipate any breakdown or breakage by proceeding to the immediate shutdown of said equipment presenting a fault. This stopping device is automated and controlled by a server located remotely, in the central station mentioned above.

Lastly, in order to proceed with the continuous improvement of the device 1 and of the algorithm managing the couple of electrical production / electrical consumption, the hours of the connections and disconnections of the mobile batteries and of the internet access of the users are taken in r-nmp-ha

In practice, the control system memorizes the exact hours and days of effective battery connections (voltage and current) and recharging times as well as hours and days of connections to the WIFI network. It then sends this data and this information by radio-telecommunication for the purposes, in particular, of behavioral analysis of the users, which allow the continuous improvement of the algorithm of the device managing said couple electricity production of the device / consumption of the device.

As regards the means of identification, its role and operation will be detailed later in the description.

Anyway, the various additional components mentioned above also require an electrical power supply according to an alternating signal, they are also connected

- 19at at least one inverter 7 or storage batteries 60, for a power supply via the photovoltaic panels 20 or via said batteries 60, depending on the available electrical energy.

In addition, it should be noted that, in a particularly advantageous manner due to the original design of the present device, these elements can be contained in the support element 3 of said device 1.

In the advantageous embodiment shown in the figures, these elements can be contained in one and / mj in .......

the other of the containers 31, 32, serving as support element 3.

In addition, essentially, the distribution of the energy which is produced by the production means 2, in other words by the photovoltaic panels 20, to the various elements of the device 1 of the invention, storage batteries 60, electrical connectors 8 , etc., is managed by a control system which comprises, at least, means for managing the storage and distribution of the energy produced by said production means 2.

Indeed, depending in particular on the time of day, the power produced by the panels 20, the charge of the internal storage batteries 60, the electrical energy demand of the various consumers, namely in particular the internal organs of the device 1, the mobile batteries when recharging, electronic telecommunications, refrigerator (s), etc. vary.

The control system therefore has the function of managing the distribution of the electrical energy directly produced in order to assign it as a priority to the different loads and, for the excess capacity produced, to recharge the internal storage batteries 60. Alternatively, the system manages the distribution of electrical energy from the storage batteries I to the various loads at least for the;

internal operation of device 1 then, if the capacity | sufficient for different loads, in particular} the electrical connectors 8. connecteurs

-20A this end, in one embodiment P ^ar ticularly interesting, said means for managing the storage and the energy distribution of the pi 1 hostage system include at least:

- A server, which is preferably in communication with a communication unit itself receiving, for example by Bluetooth, information coming, at least, from the output of the inverters 7;

- A plurality of microcontrollers, themselves under the _________ control of said ser_ve.ur ....._ e_t_commandés — par — ce — last, for example in IP;

- A relay for each electrical connector 8, the relays being controlled by a microcontroller, knowing that a microcontroller can control a single or a plurality of relays. A relay makes it possible to supply an electrical connector 8 or not. The inputs of the relays are advantageously installed in an electrical box 11;

- Possibly a relay connected to each of the optional additional components of the device 1 mentioned above, namely, for example, at least a refrigerator 9 and / or a means of ventilation and / or electronic telecommunication means and / or lighting and / or an identification means, of the barcode reader type for mobile batteries;

A charge and discharge regulator 10 for each internal means of storing electrical energy 6, in other words for each storage battery 60, said regulator 10, associated with an inverter-charger, making it possible to avoid discharges of the batteries 60 too large which could reduce the life of the storage battery 60. The charge regulator 10 of each storage battery 60 checks, in particular, the voltage at the output of said battery 60 and manages the distribution of the electricity produced by the photovoltaic panels 20. The

-21 regulator 10 and its associated inverter also communicate with the server in ip.

Said energy storage and distribution management means manage, by means of software modules:

- The distribution of photovoltaic energy between, on the one hand, the storage batteries 60 and, on the other hand, the various internal organs for operating the device 1, the electrical connectors 8 for recharging the mobile batteries and / or the means of ______ telecommunication _____ electronic _____ and / or again supplying electrical energy to the additional components (refrigerator 9, etc.);

Charging mobile batteries via electrical connectors 8;

- Information concerning the production of electricity, the operating regime of the device's organs (batteries, inverters, regulators, etc.) and any failures in the event of a malfunction.

Thus, in particular, when the production of electricity from the solar panels 20 is greater than the overall energy demand of the device 1, which represents, for example, the energy consumed for internal operation (microcontrollers, energy meters, LEDs, server, etc.) of device 1 and / or the energy drawn by the different loads (recharging mobile batteries, electronic telecommunications, refrigerator, ventilation), the extra energy is stored in the internal storage batteries 60. In practical, the device 1 itself, that is to say the various internal organs dedicated to its proper functioning, consumes a non-negligible part of the energy each day just to operate, and represents the main load, in front of the connectors / batteries and radio-telecommunication.

When, on the contrary, the energy produced by the panels 20 is not sufficient to support the load of the various components of the device 1 recalled above, the

-22 internal storage batteries 60 intervene in order to deliver the energy that remains to be supplied.

According to a particular embodiment, said energy storage and distribution management means comprise two energy meters associated with each of the electrical connectors 8, one of the two meters being redundant in the event of failure of the first, said meters advantageously being electrically connected to the server.

Each meter is capable, on the one hand, of reading the energy distributed, the current and the voltage delivered to the connector 8 with which it is associated and, on the other hand, of sending the information collected to the server.

This makes it possible to determine the state of charge of a mobile battery connected to an electrical connector 8 and, consequently, to suspend the supply of electrical energy to said connector 8 when said mobile battery is at the end of charging.

In addition, advantageously, the values which are transmitted to the server by the counters also make it possible to give information on the behavior of the users and the operation, at a given instant I, of the device 1 of the invention, such as the time and the charging time of the mobile batteries, the energy distributed to each mobile battery, or even the total energy distributed in a day by said device 1. Said information is transmitted by the radio-telecommunication system in real time.

To manage the distribution of electricity in the device 1 of the invention, the control system will constantly consult the state of charge of the internal storage means 6 in order to supply or not power elements such as the electrical connectors 8, electronic telecommunications means, refrigerator 9, etc ...

The supply order is made by means of microcontrollers controlled by the server in IP and to which the relays are connected, a relay being associated with each connector 8 and with other components of the device 1.

-23 A threshold value SI of the energy necessary for the minimum operation of all the device 1 of the invention must always be available, in a general manner, in the internal storage means 6, and this in order to be able to anticipate a sudden drop of the production of electricity by the photovoltaic panels 20 due to a passage of clouds for example.

The energy stored at the threshold value SI will make it possible to supply the means for the control system of the device 1, in particular the server, the microcontrollers, the meters, etc., _________ especially when the photovoltaic panels 20 no longer produce energy, especially at night.

This threshold value Si corresponds to a certain capacity of the internal storage batteries 60. It can vary depending on the hours of the day and, in an exemplary embodiment, it has been defined by simulation: for example, from 8 am to 3 pm hours, a threshold value SI has been determined and, from 3 p.m. to 6 p.m., a threshold value, for example Si ′, greater than the threshold value SI, has been determined.

The control system can therefore determine the actions to be followed as a function of the state of charge of the storage batteries 60 and the hours of the day.

From 8 am to 3 pm, for example, when the energy available in the internal storage batteries 60 is less than the threshold value SI, the system enters a disconnected state. This state makes it possible to disconnect the various charges according to a precise protocol in order to allow the storage batteries 60 to recharge until reaching an available energy greater than the threshold value SI and called value S2.

Advantageously, the disconnection protocol is as follows:

- Phase 1: The server interrogates the power supply system of the electronic telecommunication device of the Wifi / GPRS server type to see whether it is powered or not. If it is powered, the server disconnects it for 20 minutes. After 20 minutes, the server queries

The storage means 6 and checks the available energy, if the storage means 6 have reached a capacity greater than the threshold value SI, in practice a predetermined value S2, the electronic telecommunication means are reconnected. If this is not the case, the electronic telecommunication means remain disconnected and we go to phase 2. The value S2 to be reached leads to leaving a buffer zone of available energy (S2 - SI) making it possible to avoid the system to connect and disconnect the devices in an untimely manner, _accelerating the aging of the equipment .........

- Phase 2: The server interrogates the power supply systems of the electrical connectors 8 in order to determine the connectors 8 which are supplied and those which are not. In the case where no connector 8 is supplied, we go to phase 3. Otherwise, the server interrogates the electrical connectors 8 supplied and detects the two connectors 8 (ni = 2) which have the longest time to loading. These connectors 8 are disconnected for 20 minutes. At the end of these 20 minutes, the server interrogates the storage means 6 and checks the available energy. If the storage means 6 have reached a capacity greater than or equal to the value S2, the connectors 8 are reconnected as well as the electronic telecommunication means. If this is not the case, the server resumes the disconnection phase 2 by incrementing by 2 (n ₂ = 2) the number of electrical connectors disconnected while keeping the electronic telecommunication means disconnected as long as the storage means 6 n 'have not reached a capacity greater than or equal to the value S2. When this capacity is reached, all the connectors 8 which have been disconnected, and the electronic telecommunication means, are again supplied with power. If said capacity is not reached, the server loops again the disconnection phase 2 until all of the electrical connectors 8 in operation are stopped (i.e. connected to a battery type device mobile) and the piloting system then proceeds to phase 3.

- Phase 3: The server interrogates the supply system of the refrigerator 9 in order to verify that it is supplied. If the refrigerator 9 is not supplied with power, we go to phase 4. If the refrigerator 9 is supplied, the server orders the supply system of the refrigerator 9 to no longer supply it for 20 minutes. At the end of 20 minutes, the server interrogates the storage means 6. If these have a capacity greater than the value S2, the server again supplies the electronic telecommunication means, the 10 connectors 8 which have been disconnected as well as the fridge

9. Otherwise, the refrigerator 9 remains disconnected and we go to phase 4.

- Phase 4: The energy available in the storage means 6 is not sufficient to supply the control elements in the event of insufficient production of the photovoltaic panels 20. The server sends an alert to the operator, in control remotely in its central station, in order to signal the insufficient energy in the storage means 6, then all the sensors are disconnected except for the 20 energy sensors of the storage means 6. When the latter have reached the value S2, all the elements which have been disconnected are supplied again.

- In the event of total disconnection resulting from zero energy in the storage means 6 and from zero photovoltaic production, the server and the various organs of the device 1 restart as soon as they are replenished with energy.

In addition, due to the production of intermittent photovoltaic electrical energy, and to optimize both the number of solar panels 20 and the capacity of internal storage batteries 60, only part of the mobile batteries which are distributed to the inhabitants can be charged per day, compared to all the mobile batteries which are associated with the device 1.

Throughout the day, the power of the electrical connectors 8, and therefore the charge of the mobile batteries which there

-26 are connected, is managed by the management means of the control system of the device 1 as a function of the energy available in the storage batteries 60.

Optimal use of mobile batteries as defined above in the detailed description, namely supplying a lighting system and recharging small electronic devices, allows said mobile batteries to have a range of several days, in particular three days.

10___La_recharge_diune_batter i.e_mobi le_par_le_di sposit i f__1 ..... of the invention is therefore advantageously authorized by the piloting system every three days.

For this purpose, the mobile batteries are equipped with an identifier of the barcode type and, for the record, said device 1 is equipped with at least one identification means, of the barcode reader type, capable of decrypting the identifier found on each mobile battery.

Advantageously, said identification means, in the form of at least one barcode reader equipped with at least one display means, screen type, is positioned on 1'61 emtanf · support 3, in the occurrence on at least one and / or the other container 31, 32, in the preferred embodiment in which the device 1 comprises two containers 31, 32, as support element 3.

When a mobile battery must be recharged, the identifier on said battery is passed in front of the identification means.

This sends the decrypted identification of the mobile battery to the control system, for example via a USB connection, which verifies, in the database, that the identifier corresponds to a mobile battery which has been recharged there is , for example, three days.

In the case where the last recharge took place less than or more than three days ago, the piloting system sends an error message 35 to be displayed on the screen of the identification means for

-27 indicate the refusal of charging and the day of the next possible charge for the mobile battery in question.

This refusal is also part of the information which is collected and sent in a database of the server, as well as the date T and the precise time tl at which the mobile battery was identified.

However, the date of the last charge remains unchanged.

In the case where the last recharge was carried out three days ago, the control system enters the date and time of the reading of the mobile_identified battery in the database of the server and allows the recharging of the battery. mobile concerned.

As for the management of the charge and discharge of the internal storage batteries 60, the control system manages the power supply of the electrical connectors 8 for recharging the mobile batteries by means of microcontrollers to which relays are connected, said microcontrollers being controlled by the server in IP.

Preferably, a number is assigned to each of the electrical connectors 8 intended to receive the mobile batteries for recharging. These numbers are written on the support element 3, for example on the containers 31, 32 on the faces of which the connectors 8 are positioned and in the database.

When the mobile battery charge has been authorized, the server identifies an electrical connector 8 not yet supplied then sends the information, that is ^- a ^- say the number of the connector 8 identified, on a display means, example, but not limited to the screen associated with the identification means, and being located on one of the faces of the support element 3.

Advantageously, around each of the electrical connectors 8 are arranged one or more LEDs which are lit or not depending on the state of the connector 8. Most preferably, these LEDs are also managed by the control system, by means of microcontrollers controlled in IP by the server and connected to relays.

-28When an electrical connector 8 is assigned to a mobile battery, the corresponding LED (s) flash (es), for example, thus making it easier to locate connector 8.

The server then advantageously checks that the power to be supplied to supply the electrical connector 8 is available and that the control system is not in a disconnected state to compensate for the insufficient energy available in the internal storage battery 60 less than the threshold value 10

These two parameters will define the power supply to connector 8 or not:

- Disconnection state or insufficient power to supply connector 8: the server orders the LEDs flashing around electrical connector 8 allocated to the charge of the mobile battery. As long as the disconnection state is not lifted, the electrical connector 8 is not supplied, the LEDs continue to flash and the server does not recover the start time for loading. When the disconnection state is lifted, the control program applies the protocol for the connection state as defined below:

- Connection status and sufficient power to supply the electrical connector 8: the server orders the LEDs flashing around the electrical connector 8 assigned to the charge of the mobile battery. The server retrieves the time at which said mobile battery was identified as well as the value of the charging current displayed on the counter of the electrical connector 8 allocated to the battery in question. During a period of m minutes, for example between 1 30 and 4 min, preferably for 2 min, after the identification time of the mobile battery, the server interrogates in a loop the value of the charge current of the counter of the electrical connector 8 assigned to the battery charge.

• If this charge current value is greater than 35 the previous value, this means that the mobile battery has connected to the electrical connector 8, and

-29that there is charge of said battery. The server therefore writes the date and time of day as the date and time of the last charge and orders the LEDs to go from the flashing state to the on state. The server will regularly consult the counter in order to check the state of charge of the mobile battery by identifying a decrease in the charging current. When the charging current decreases, the electrical connector 8 is no longer supplied with power and the _____________ mobile_battery is considered to be charged ___ If the charging current does not decrease after 4 hours of effective connection (except disconnection), the electrical connector 8 is still disconnected and the mobile battery considered to be charged.

• If the counter value is the same as the previous value, it means that the mobile battery has not been connected. The server stops supplying the electrical connector 8 and indicates in the database that the mobile battery is not connected. However the server will not write the current date as the date of last loading, but will keep the previous date.

The autonomous device 1 for producing, storing and distributing electricity according to the present invention is particularly advantageous. As has been demonstrated in the description of the preceding invention, it is a fully autonomous, compact device 1, of easy assembly and use, making it possible to bring energy into remote areas of developing countries and not having a sufficiently developed network.

More specifically, the elements of the device 1, and in particular the support element 3, which may consist of containers 31, 32, easily transportable by land and / or sea, can include all the material necessary for mounting and operating the device 1.

Of course, the invention is not limited to the examples illustrated and described above which may have variants and modifications without departing from the scope of the invention.

For example, the device 1 according to the invention described in detail above may be provided with a system of T ^ra it ^em ®nt water, e.g. osmosis type brine processing system reverse. Such a system makes it possible to treat salt water to transform it into drinking water and can be ----- 10 - in s ± al lé in support support element 3 of the device 1, otherwise di t in one and / or in the other container 31, 32.

In this embodiment, the water treatment system can be powered by solar energy produced by the photovoltaic panels 20 and / or by the energy stored in the internal storage means 6. In addition, it is then it is conceivable to provide for the fitting of a ramp of ten taps on the outside of one and / or the other of the containers 31, 32 for distribution.

The control system of the device 1 of the invention will then be programmed to accommodate the distribution of energy between the electrical connectors 8 and / or the water treatment system, and / or the refrigerator (s) and / or electronic telecommunications, etc.

In another example, where the device 1 is implanted inside an earth and is located near a water point other than salt water, the water treatment system is replaced by pumping means.

In all configuration cases, the invention is easy to implement on site, since the containers are largely pre-assembled in the factory, in advance. This allows very reduced on-site assembly operations, relating to only a few elements not assembled in the factory and transported in the device 1, which must therefore be installed on the electrical production site.

It should also be emphasized that the devices according to the invention are dimensioned so that the production

-31 photovoltaic electric covers at all times all of the charges (internal organs and / or electrical connectors and / or electronic telecommunication means and / or refrigerator, etc.) and make it possible to ensure energy for the whole of users associated with the device - that is to say benefiting from an identifier - and whose number has been maximized and predetermined for each device.
