Description

Patent application for invention entitled "Structure of charging station for electric vehicles and related construction system"

DESCRIPTION

The object of the invention which is the subject of the present patent application is to provide a device for refueling vehicles, particularly but not exclusively electric or plug-in hybrid vehicles, said device being characteristic in that it is modular.

As is known, electric vehicles have an electric socket through which it is possible to refuel an accumulation system inside the vehicle; the recharging process can be carried out according to the main methods briefly described below:

Mode A: via a simple cable.

Mode B: via a cable equipped with an integrated controller, called EVSE, connected to an electrical socket or a cable equipped with a fixed EVSE integrated controller permanently connected to the electrical network and connected to the car via a cable from the cable equipped with an EVSE integrated controller same.

Mode C: via a removable adapter cable associated on one side to the vehicle and on the other to the fixed socket located at the integrated EVSE controller device which supplies an alternating voltage.

Mode D: for connection to a direct voltage EVSE.

In charging modes B, C, the EVSE integrated controller carries out safety checks for the transfer of the mains voltage to the vehicle.

In the case of connection with direct voltage (Mode D), the charging circuit that converts the alternating voltage into direct voltage is placed inside the EVSE system and not on the vehicle.

The invention which is the subject of the present patent application finds application in particular in the recharging methods C and D described above or, after installing one or more standard electrical sockets, in the methods A and B in the case of recharging vehicles such as cycles and motorcycles.

It is known that electric charging stations for vehicles consist of an EVSE controller in the form of a wall box (called a wallbox) or a column fixed to the ground (called a column) equipped with a socket or cable with plug.

Typically these solutions involve the construction of a standardized charging station in which sometimes during the molding phase of the external chassis it is possible to pre-cut a series of openings for housing the sockets and in the final assembly phase only the sockets required by the client without completing the pre-cut and unused openings.

Although this solution is performing as regards flexibility in production as it allows you not to have to create a different container for each variant; however, this solution does not allow the subsequent implementation or removal of functionality and limits the possibilities of repairing the charging station itself.

At the state of the art, there are known solutions in which the charging station is made up of more than one independent charging system associated with a common support and simultaneously associated with each other; in particular, document CA2811149 describes a modular charging station which is the result of an assembly of the components of the single charging system (cable - EVSE controller - mechanical support) and the association of up to 4 devices is envisaged in the modular assembly configuration.

Said solutions consist of characteristic devices in that they have such a conformation in the space as to limit the number of them in the possible combination; in addition, the solutions described in the state of the art allow the combined realization of a single type of delivery mode, thus limiting the versatility of the device resulting from the association of the individual modules.

Last but not least, the state of the art describes devices resulting from the association of multiple modules having a structure such as to require the use of particular molds for the realization of the same.

The purpose of the invention, which is the subject of the present patent application, is to solve the identified disadvantages of the state of the art, in particular by providing a solution composed of several units associated with each other, each unit being in such a configuration as to allow the modification or implementation of the device in a manner fast and cheap.

The modular construction also allows intervention on the single unit, simplifying the procedure both from an operational and an economic point of view.

The invention which is the subject of the present patent application is represented by way of non-limiting example in the attached Tables in which

With reference to the attached figures, in a preferential but not exclusive configuration, the recharging station object of the present patent application (200) is installed on a generic support (104) preferably but not exclusively constituted by a raised element of the sidewalk type, placed in proximity to generic car parking areas (102, 103).

The recharging station (200) is made up of a series of elements (101,101 ', ... 10 <n-1>, 101) having identical dimensions, each of which consists of a regular vertical polygon equipped with a base ( 301) and a height (401).

Each vertically developed element (101,101 ', ... 101 <n-1> 101) is associated with the next developing element

associated with a subsequent vertical element (101 <1>) forming a regular prismatic solid with a lower base (110 ') not visible in the figure and an upper base (110) preferably but not exclusively constituted by a generic cover associated with the extremity superior of the single elements (101,101 ', ... 101 <n 1>, 101 <n>) with two bases (110,110').

As previously described, the perimeter of the lower base (110 ') and the perimeter of the upper base (110) is made up of the sum of the bases (301) of the individual elements (101, 101', ... 101 <n-1>, 101); according to what previously described, each element (101, 101 ', ... 101 <n-1>, 101) constitutes one side of the surface of the regular prismatic solid whose height therefore corresponds to the height (401) of the individual elements (101,101' , ... 101 <n 1>, 10Γ).

According to what was previously described, the polyhedral solid formed by the individual elements (101,101 ', ... 101 <n 1> 101 <n>) is internally hollow except for the electronic devices necessary for operation (EVSE).

In a first preferential embodiment (Table 2, Fig 2,3), the association between the individual elements (101,101 ',. .. 101 <n 1>, 101) is achieved by means of a profile (600) having a L, said profile (600) being provided with a first end (601) and a second end (602) said second end (602) forming with the first end (601) an angle a = 90 °.

The first end (601) and the second end (602) have a seat (603) where the lateral end of the generic element (101,101 ', ... 101 <n -1>, 101) is housed which is associated with the profile (600) by means of generic means of association and insulation from atmospheric agents (Fig 3)

Depending on the relative angle between the first end (601) and the second end (602) it is therefore possible to obtain a polygonal solid with a variable surface configuration which constitutes the charging station (200).

In particular, with reference to Fig 4, the profile (600) consists of a first end (601) which forms an angle a = 90 ° with the second end (602) for the construction of the recharging station (200) with a square plan or rectangular.

With reference to Fig 5, the profile (600) consists of a first end (601) which forms an angle a = 60 with the second end (602). This configuration of the profile (600) allows the association of 6 elements to create a charging station (200) with a hexagonal plan as in Fig 1. With reference to Fig 6, the profile (600) consists of a first end ( 601) which forms an angle a = 72 ° with the second end (602). This configuration of the profile (600) allows the association of 5 elements, creating a recharging station (200) with a pentagonal plan.

In a second preferential embodiment (Table 2, Fig 7), the association between the individual elements (101, 101 ', ... 101 <n-1>, 101 <n>) is achieved by means of a profile (700) having a U-shaped configuration, said profile (700) being formed by two ends (701, 702) both having a seat (602) for housing the elements (101,101 ', ... 101 <n- 1>, 101n) .

The shape of the profile (700) allows the insertion of two elements ((101, 101 101 <n-1>, 101 <n>) to create a recharging station (200) with a rectangular plan.

With reference to Table 3 and regardless of the configurations of the profile (600), each single element (101, 101 101 <n- 1>, 101 <n>) is potentially differently functionalized according to the construction / performance needs of the charging station.

In an exemplary but not exclusive form (Table 3) a first generic element (101, Fig 8c) provides a fixed or roll-up cable (402) through an internal mechanism, ending with a standard charging socket for electric vehicles (403) and a anchoring system to rest the grip after use (404). By way of example but not exclusively, the generic element (101) can provide a display (405).

With reference to Table 3, by way of simplification but not exclusively, a second generic element (101 <1> Fig 8a) has a display (406) and a possible payment system (407), preferably but not exclusively by credit card.

With reference to Table 3, by way of example but not exclusively, a third generic element (101 Fig 8b) is arranged in such a way as to allow the inspection of the charging station or the installation of new elements; the third generic element (101 <n>) therefore has an access element (408) and a generic lock (409).

In a preferential form, a fourth generic element (101 'Fig 8d) has one or more standard charging sockets for plug-in vehicles (410) and preferably but not exclusively a display (41 1).

Depending on the desired configurations and installations, the further generic elements that make up the sides of the surface of the polygonal solid (200) can consist of panels without functional elements, which can be replaced as needed with functionalized elements of the type described.

According to what was previously described, the recharging station (200) is made by associating, by means of a profile (600,700) one or more panels of the type (101) or one or more panels of the type (10T) or one or more panels having identical or variable configuration

With reference to Table 4, Fig 9, a preferential but not exclusive form of the recharging station (200) made according to the invention which is the subject of the present patent application provides for the construction of the station (200) in a hexagonal plan.

At least two modules (101) equipped with cable (402) and socket and at least one module (101) equipped with an opening for maintenance and / or installation of new elements are positioned along the transversal plane to the vehicle parking areas (102,103) functionalized.

The preferential but not exclusive embodiment with a hexagonal plan lends itself to serving four car parks by installing socket or cable modules facing the street, while the user interface module and the maintenance hatch can be installed on the two remaining sides (209).
