Description

Electrical distribution circuit for vehicle parking lot

The present invention relates to the field of modular electrical distribution systems and more particularly to the field of modular electrical distribution systems for charging vehicles.

As part of the programs put in place to reduce dependence on fossil fuels, vehicles powered totally or partially with renewable energy are the subject of significant development. Also, the number of vehicles in circulation that use electricity as driving energy is gradually increasing so that it is becoming essential to support this growth by jointly developing stations allowing these vehicles to recharge.

While the number of electric vehicles has significant development potential, its current place in the fleet in operation is still particularly limited. Also, to decide on the installation of a station intended for the recharging of electric vehicles, the criterion of its profitability inevitably arises.

Indeed, with regard to the solutions currently proposed, the installation of a charging station which includes several terminals or points for the connection of electric vehicles imposes the realization of important works and in particular of an expensive structural work, even when it is only a question of proceeding with the installation of a few connection points. In addition, during the future development of the electric charging station to meet the future growing needs of users, the addition of additional terminals will require the construction of new structural works imposing the consequent costs associated therewith. However, such a solution is complex to implement because, given the sums to be committed at each stage of expansion of the charging station, it is imperative to perfectly anticipate the electrical charging needs that the station will have to meet. Moreover, such a solution for the distribution of electricity within the charging station does not make it possible to operate an optimized adjustment of the number of charging points according to the evolution of the needs, whether this evolution of the needs is attached to the development of the electric vehicle market or in connection with one-off or even seasonal needs.

The object of the present invention is to overcome these drawbacks by proposing a technical solution which is easy to implement to ensure the distribution of current between several connection points for vehicles in a charging station while allowing, on the one hand, a adaptation to the needs of connection points and, on the other hand, a reduction in the importance of the structural work to be carried out for the implementation of the solution.

• au moins une ligne secondaire de distribution 2 comprenant, d’une part, une interface de connexion 21 avec la ligne principale de distribution 1 et, d’autre part, au moins une interface de connexion 25 avec une interface dédiée 51 d’un dispositif d’alimentation 4 d’un véhicule,
• au moins une ligne d’alimentation 5 entre une interface de connexion 51 avec une ligne de distribution 2 différente de la ligne principale 1 de distribution et une interface de connexion 6 d’un véhicule avec le dispositif d’alimentation électrique 4,

la ligne principale de distribution 1 étant positionnée dans un logement situé dans un bâti immeuble du stationnement, au moins une ligne secondaire de distribution 2 étant positionnée de niveau ou au-dessus de la surface du stationnement.The invention relates to an electrical distribution circuit for a vehicle parking lot comprising at least two parking spaces 8 intended to receive a respective parked vehicle, each parking space 8 being associated with an electrical power supply device 4 of a parked vehicle, characterized in that the distribution circuit comprises:

• a main distribution line 1 comprising, on the one hand, a connection interface 11 with an external power supply network and, on the other hand, at least one connection interface 12 with a secondary distribution line 2,
• at least one secondary distribution line 2 comprising, on the one hand, a connection interface 21 with the main distribution line 1 and, on the other hand, at least one connection interface 25 with a dedicated interface 51 of a device supply 4 of a vehicle,
• at least one supply line 5 between a connection interface 51 with a distribution line 2 different from the main distribution line 1 and a connection interface 6 of a vehicle with the power supply device 4,

the main distribution line 1 being positioned in a housing located in a building frame of the parking lot, at least one secondary distribution line 2 being positioned at or above the surface of the parking lot.

The distribution circuit of the invention thus proposes an arrangement whose constraints related to a structural work are strictly restricted to the integration of only the main distribution line 1 in a building frame. Also, from the main distribution line 1, the architecture of the distribution circuit is able to be organized to allow a multiplication of the branching of the electrical distribution according to the number of secondary distribution lines 2 connected to this main line distribution 1, each secondary distribution line 2 being capable of supplying electricity to a supply device 4 of a vehicle. Furthermore, the positioning on the surface of the secondary distribution lines 2 allows the distribution by the circuit to overcome the rigidity of an installation integrated into a building frame to allow a free spatial distribution, if not limited only by the properties of the lines. distribution 2 surface. The spatial arrangement of the surface distribution lines 2 is therefore adjustable to the requirements of the environment so that, on the parking surface, the distribution of the vehicle supply devices 4 is able to be organized on the basis of criteria external to the constraints of the building. Similarly, this arrangement of the distribution circuit of the invention is modular to be adapted to changes and developments likely to affect the architecture of the surface of the parking lot or variations in the electrical power requirements of vehicles. The modifications which affect, on the one hand, the layout of the electrical power supply devices 4 of the vehicles in the car park and, on the other hand, the electrical distribution which supplies these devices 4 and in particular the tree structure of this circuit of the invention are therefore independent of the frame attached to the car park. The main distribution line 1 integrated into a building frame of the parking lot does not restrict the organization of the electrical power supply devices 4 of the vehicles on the parking lot and its possible modifications.

In the distribution circuit of the invention, the power supply device 4 is positioned at the end of the circuit to provide charging points for parked vehicles. At least some of these power supply devices 4 are arranged to form a junction between the vehicle to be recharged and the secondary distribution line 2 of the circuit. This junction thus involves in particular a power supply line 5, at least partly housed inside the electrical power supply device 4, between, on the one hand, a particular connection interface 25 of a secondary distribution line 2 and, on the other hand, a connection interface 6 of a vehicle with the power supply device 4.

According to a particular example of construction, the distribution circuit also comprises at least one tertiary distribution line 3 comprising, on the one hand, at least one connection interface 32 with a connection interface 23 dedicated to a secondary distribution line 2 and, on the other hand, at least one connection interface 35 with a dedicated interface 51 of an electrical power supply device 4 of a vehicle. The integration of one or more tertiary distribution lines 3 in the distribution circuit of the invention makes it possible to operate a multiplication of the tree structure of the electrical distribution on the surface of the car park. It should be noted that preferably, in the context of a distribution circuit which comprises one or more tertiary distribution lines 3, one or more electric power supply devices 4 for a vehicle involves a power supply line 5 housed at the least partly inside the electrical power supply device 4 between, on the one hand, a connection interface 35 of a tertiary distribution line 3 and, on the other hand, a connection interface 6 of a vehicle with power supply device 4.

According to another particular example of construction, at least one pair of connection interfaces 12, 21 or 23, 32 which operates the junction between two distribution lines of different respective ranks, is juxtaposed with at least one connection interface 15, 25 , 35 intended to operate a junction with a dedicated interface 51 for supplying electric current to a supply device 4 of a parked vehicle. It is appropriate here to understand the term "juxtaposed" as qualifying the spatial proximity between, on the one hand, the pair of connection interfaces 12, 21 or 23, 32 between distribution lines 1, 2, 3 and, on the other hand, a connection interface 15, 25, 35 of the distribution line 1, 2, 3 configured to interact with an interface 51 of the power supply device 4 in order to supply current for charging a vehicle. According to a specific variant of this particular example, this spatial proximity is configured to be integrated inside a vehicle supply device 4, for example at the base thereof. According to another specific variant of this particular example, this spatial proximity is arranged to be integrated inside a base or a base at which the vehicle supply device 4 is mounted. According to this variant, the base or the base forms a support interface for the vehicle supply device 4 on the surface of the parking lot. According to a specificity of this particular example, a vehicle power supply device 4 is thus positioned at the level of at least one node of the tree structure of the distribution circuit. In the distribution circuit, a node corresponds to the junction between, on the one hand, a first distribution line and, on the other hand, a second distribution line of lower rank than the rank of the first line, such that, for example, the junction between the main distribution line and a secondary distribution line or even the junction between a secondary distribution line and a tertiary distribution line.

According to another particular example of construction, the distribution circuit comprises at least one electrical distribution protection device 7 positioned at the level of the junction between the dedicated connection interface 12, 23 of a first distribution line and the dedicated connection interface 21, 32 of a second distribution line of lower rank than the first distribution line, the breaking device 7 being positioned upstream of the dedicated connection interface 12, 23 of the higher distribution line high rank. The electrical protection device 7 corresponds to any mechanism capable of and intended to effect a break in the distribution of the electrical current from the external power supply network in the direction of the power supply devices 4 of the vehicle. Thus, in the circuit of the invention, one or more electrical protection devices 7 are positioned at the junction between the main distribution line 1 and a secondary distribution line 2 or also between a secondary distribution line 2 and a tertiary distribution line 3. In order to optimize the effectiveness of the electrical protection at the junctions of the distribution lines of the circuit, the protection devices 7 in charge of stopping the supply are positioned upstream of the dedicated connection interface 12, 23. Such an arrangement allows the realization of a circuit architecture within which the whole of the distribution line of lower rank is protected from the actuation of the electric break by the protection device 7, and therefore all the lines, installations and devices connected to it downstream. It should be noted that each of the protection devices 7 integrated into the distribution circuit is preferably selected so that its reaction capacities are adapted to the characteristics of the electric current distributed at the point of the circuit where the protection device 7 is installed. Thus, according to a particular example of implementation, a protection device 7 installed at the level of the junction between the main distribution line 1 and a secondary distribution line 2 is capable of breaking an electrical power of the order of 210 kW. At the level of the junction between a line, a secondary distribution line 2 and a tertiary distribution line 3, the protection device 7 installed is capable of allowing an electrical power failure of the order of 42 kW. At the level of the junction between a supply line 5 of a vehicle supply device 4 and a secondary 2 or tertiary 3 distribution line 3, the protection device 7 installed is capable of performing a current break of at least one connection interface 6 for a vehicle with an electric power of the order of 7 kW. Also, with regard to the electrical power protected in this particular example, the connection of a secondary distribution line 2 to the main distribution line 1 makes it possible to simultaneously ensure the supply of around thirty connection interfaces 6 in operation to charge a respective vehicle.

• au moins une ligne secondaire de distribution 2,
• au moins une ligne tertiaire de distribution 3,
• au moins un dispositif d’alimentation 4 électrique d’un véhicule et la ligne d’alimentation 5 associée.

Il convient de relever que l’intégration d’interfaces de connexion permettant la mise en œuvre d’opérations de branchement/débranchement automatiques assure une optimisation de l’installation du circuit de distribution de l’invention et facilite la modification ou la réorganisation ultérieure de l’architecture de ce circuit de distribution par un intervenant sans nécessiter des opérations techniques lourdes ou trop importantes. En effet, dans le cadre d’une utilisation d’interfaces de connexion de typePlug & Play, les éléments ou dispositifs réunis lors de la connexion sont susceptibles d’opérer une reconnaissance mutuelle permettant d’assurer leur compatibilité de fonctionnement sans nécessiter de paramétrage particulier de la part de l’intervenant. Selon un exemple de mise en œuvre, les connexions au niveau des interfaces dédiées 12, 21, 23, 25, 32, 35, 51 sont amovibles et réalisées par contact, sous contrainte élastique, entre, d’une part, des premiers moyens qui présentent la forme de broches, de tiges ou analogues et, d’autre part, des seconds moyens adoptant la forme de surfaces d’appui, de réception ou analogues. Selon une réalisation préférée des interfaces de connexion 12, 21, 23, 25, 32, 35, 51, les interfaces de typePlug & Playsont équipés de détrompeurs, tels que mécaniques, magnétiques, colorés et/ou de tout autre type. Cet équipement permet ainsi de restreindre, voire supprimer, le risque d’une éventuelle erreur d’assemblage des interfaces de connexion entre elles. De façon complémentaire, ces interfaces de connexion 12, 21, 23, 25, 32, 35, 51 remplissent préférentiellement les conditions nécessaires pour garantir un indice de protection, référencé IP, dont la valeur élevé, c’est-à-dire correspondant à une valeur de classe, selon la norme européenne EN60529, qui soit au moins de valeur IP2x sinon supérieure. Cette garantie technique de protection au niveau des interfaces de connexion utilisées autorise une intervention sur ces équipements par du personnel ou des utilisateurs dont les qualifications nécessaires sont minimales. Aussi, des opérations telles que la maintenance ou une mise en place de nouveaux dispositifs pour l’alimentation de véhicules, dans le cadre d’une installation ou d’une extension du circuit de distribution de l’invention, sont susceptibles d’être effectuées par des individus ne disposant que d’une habilitation électrique simple. Cette garantie de sécurité optimisée quel que soit l’intervenant, participe également à la réduction des frais à engager pour opérer sur un circuit de distribution comme celui de l’invention.According to another particular example of construction, at least one pair of connection interfaces 12, 21, 23, 25, 32, 35, 51 is of the automatic connection/disconnection type also called Plug & Play between at least two elements among:

• the main distribution line 1,
• at least one secondary distribution line 2,
• at least one tertiary distribution line 3,
• at least one electrical power supply device 4 of a vehicle and the associated power supply line 5.

It should be noted that the integration of connection interfaces allowing the implementation of automatic connection/disconnection operations ensures optimization of the installation of the distribution circuit of the invention and facilitates the subsequent modification or reorganization of the architecture of this distribution circuit by a participant without requiring cumbersome or excessive technical operations. Indeed, in the context of the use of Plug & Play type connection interfaces, the elements or devices brought together during the connection are likely to operate a mutual recognition making it possible to ensure their compatibility of operation without requiring configuration. particular on the part of the speaker. According to an example of implementation, the connections at the level of the dedicated interfaces 12, 21, 23, 25, 32, 35, 51 are removable and made by contact, under elastic stress, between, on the one hand, first means which have the form of pins, rods or the like and, on the other hand, second means adopting the form of support surfaces, reception or the like. According to a preferred embodiment of the connection interfaces 12, 21, 23, 25, 32, 35, 51, the Plug & Play type interfaces are equipped with polarizers, such as mechanical, magnetic, colored and/or of any other type. This equipment thus makes it possible to restrict, or even eliminate, the risk of a possible error in assembling the connection interfaces between them. In a complementary manner, these connection interfaces 12, 21, 23, 25, 32, 35, 51 preferably fulfill the conditions necessary to guarantee an index of protection, referenced IP, whose high value, that is to say corresponding to a class value, according to European standard EN60529, which is at least IP2x if not higher. This technical guarantee of protection at the level of the connection interfaces used authorizes intervention on this equipment by personnel or users whose necessary qualifications are minimal. Also, operations such as maintenance or installation of new devices for supplying vehicles, as part of an installation or extension of the distribution circuit of the invention, are likely to be carried out. by individuals with only a simple electrical qualification. This guarantee of optimized safety, regardless of who is involved, also contributes to the reduction of the costs to be incurred in order to operate on a distribution circuit like that of the invention.

The invention also relates to a vehicle parking lot comprising a juxtaposition of parking spaces 8 intended to receive a respective parked vehicle, each parking space 8 being associated with a connection interface 6 of a vehicle carried by a device power supply 4, characterized in that the parking lot comprises at least one distribution circuit according to the invention. According to a particular variant of the arrangement of the parking lot, one or more of the power supply devices 4 carry a pair of connection interfaces 6 for the vehicle. This particular construction of the electrical power supply devices 4 in combination with a positioning of the power supply device 4 at the level of the junction of two juxtaposed parking spaces 8 allows, from a single power supply device 4, to operate simultaneous supply of two parked vehicles.

• au moins une ligne secondaire de distribution 2,
• au moins une ligne tertiaire de distribution 3,
• au moins un dispositif d’alimentation 4 électrique d’un véhicule et la ligne d’alimentation 5 associée,

de sorte qu’au moins une partie du parc de stationnement est configurée pour être modulaire et/ou amovible. Aussi, la ligne principale de distribution 1 réalise le tronc de base du circuit de l’invention à partir duquel son arborescence est en mesure d’être déployée pour organiser l’architecture de la distribution électrique sur tout ou partie du parc de stationnement. L’arborescence du circuit de distribution installée de niveau ou au-dessus de la surface du stationnement est construite par la connexion à la ligne principale de distribution 1 d’au moins un module formé par l’association d’une ligne secondaire de distribution 2 avec au moins un dispositif d’alimentation 4 électrique d’un véhicule et sa ligne d’alimentation 5 associée. Aussi, l’arborescence du circuit se trouve complété, d’une part, par la multiplication du nombre de modules connectés à la ligne principale de distribution 1 et, d’autre part, par le développement de la ramification de l’arborescence par connexion de modules complémentaires aux lignes secondaires de distribution 2, ces modules complémentaires étant formés par l’association d’une ligne tertiaire de distribution 3 avec au moins un dispositif d’alimentation 4 électrique d’un véhicule. Il convient également de relever que l’arborescence de la partie du circuit de distribution installée au niveau de la surface de stationnement est susceptible d’être également complétée par un ou plusieurs modules additionnels respectivement formés par un dispositif d’alimentation 4 électrique et sa ligne d’alimentation 5 associée. Ces modules additionnels complètent l’arborescence de la distribution en étant aptes et destinés à être connecté au niveau d’interfaces dédiées positionnées sur la course des lignes de distribution principale 1, secondaires 2 ou tertiaires 3 du circuit de distribution.According to a particular example of construction, at least one pair of connection interfaces 12, 21, 23, 25, 32, 35, 51 is configured to be accessible to an installer, this pair of interfaces being of the connection/disconnection type automatic between at least two elements among:

• the main distribution line 1,
• at least one secondary distribution line 2,
• at least one tertiary distribution line 3,
• at least one electrical power supply device 4 of a vehicle and the associated power supply line 5,

such that at least a portion of the parking lot is configured to be modular and/or removable. Also, the main distribution line 1 forms the basic trunk of the circuit of the invention from which its tree structure can be deployed to organize the architecture of the electrical distribution over all or part of the parking lot. The distribution circuit tree installed at or above the surface of the parking lot is constructed by connecting to the main distribution line 1 at least one module formed by the association of a secondary distribution line 2 with at least one electrical power supply device 4 of a vehicle and its associated power supply line 5. Also, the tree structure of the circuit is completed, on the one hand, by the multiplication of the number of modules connected to the main distribution line 1 and, on the other hand, by the development of the ramification of the tree structure by connection complementary modules to the secondary distribution lines 2, these complementary modules being formed by the association of a tertiary distribution line 3 with at least one electric power supply device 4 of a vehicle. It should also be noted that the tree structure of the part of the distribution circuit installed at the level of the parking surface is also capable of being supplemented by one or more additional modules respectively formed by an electrical power supply device 4 and its line supply 5 associated. These additional modules complete the distribution tree structure by being able and intended to be connected at the level of dedicated interfaces positioned on the course of the main 1, secondary 2 or tertiary 3 distribution lines of the distribution circuit.

• un premier dispositif d’alimentation 4 est positionné au niveau de la connexion entre une première ligne de distribution et une seconde ligne de distribution de rang inférieur à la première ligne de distribution,
• un second et un troisième dispositif d’alimentation 4 sont positionnés de part et d’autre du premier dispositif d’alimentation 4 et positionnées sur la seconde ligne de distribution de rang inférieur à la première ligne de distribution.

Dans le cas présent, il convient de comprendre le terme « juxtaposé » comme qualifiant des dispositifs d’alimentation 4 positionnés à proximité les uns des autres sur le parc de stationnement, tout en présentant des écartements entre eux susceptibles d’être nécessaire pour permettre le stationnement de véhicule destinés à être rechargé par connexion aux dispositifs d’alimentation. Grâce à un tel arrangement de l’arborescence du circuit de distribution, la fourniture en électricité de deux dispositifs d’alimentation 4 parmi un ensemble de trois est opérée avec une optimisation de la longueur des lignes de distribution utilisées, notamment des lignes de distribution de rang inférieur. Cet arrangement assure ainsi une distribution d’électricité en permettant une réduction de la longueur totale de lignes de distribution.According to another particular example of construction, the distribution circuit is organized so that the parking lot comprises at least three electrical power supply devices 4 juxtaposed so that:

• a first supply device 4 is positioned at the connection between a first distribution line and a second distribution line of lower rank than the first distribution line,
• a second and a third supply device 4 are positioned on either side of the first supply device 4 and positioned on the second distribution line of lower rank than the first distribution line.

In the present case, the term "juxtaposed" should be understood as qualifying supply devices 4 positioned close to each other on the parking lot, while presenting spacings between them likely to be necessary to allow the vehicle parking intended to be recharged by connection to the supply devices. Thanks to such an arrangement of the tree structure of the distribution circuit, the electricity supply of two power supply devices 4 from a set of three is operated with an optimization of the length of the distribution lines used, in particular the distribution lines of lower rank. This arrangement thus ensures distribution of electricity by allowing a reduction in the total length of distribution lines.

Selon une autre variante de construction compatible avec les variantes précédentes, un nœud de l’arborescence du circuit de distribution entre une première ligne de distribution et une seconde ligne de distribution de rang inférieur au rang de la première ligne de distribution, éventuellement en association avec un ou plusieurs dispositif de protection électrique 7, est susceptible d’être structurellement intégré et/ou logé au niveau d’une structure du dispositif d’alimentation électrique 4.According to another particular example of construction, at least one electric power supply device 4 of a vehicle incorporates:

• a connection interface 6 of a vehicle to the power supply device 4,
• a connection interface 51 to a first distribution line and/or

It should be noted that the integration in an electrical power supply device 4 of a vehicle, of a connection interface to a second distribution line of a rank different from the first distribution line relates to a specific variant of construction . An electrical power supply device 4 of a vehicle can be included in the circuit of the invention without integrating such an additional connection interface to a second distribution line. According to different construction variants, the connection interface 6 to a vehicle and the connection interface 51 to a distribution line 1, 2, 3 are positioned in the same structure of the electrical power supply device 4 or in different structures. assembled together, for example boxes 41, 42 superimposed and between which the elements of the power supply device 4 are connected.
