Description

Technical Field

[0001] The invention relates to a modular charging device for charging so-called electric plug-in vehicles or hybrid vehicles, and to a method for managing current distribution by means of such a modular charging device.

[0002] The present invention is generally in the field of electromobility, and in particular in the field of charging systems for electric or hybrid plug-in vehicles. Background Art

[0003] The market for electric mobility (cars, motorcycles, scooters, bicycles) is growing. Most developed economies are actively planning and supporting an ecological transition to overcome or limit the internal combustion engine.

[0004] Therefore, the demand for charging points for electric vehicles is increasing, which makes the use of this mobility system more efficient and increases its popularity accordingly.

[0005] In particular, there is currently a strongly felt need to deploy a large number of charging points that may be suitable for providing the power required for charging vehicles in a fast and efficient manner.

[0006] At the same time, it is desirable to deploy a system that can charge multiple vehicles within a confined space, such as within a public or apartment building parking lot.

[0007] Known systems require the installation of charging poles, each of which is individually connected to the grid by a bundle of cables connecting each charging pole to a distribution board.

[0008] Such solutions usually consist of an EVSE (Electric Vehicle Supply Equipment) controller mounted in a wall box or a box fixed to a pole in the ground, with a socket or a cable with pins.

[0009] Disadvantageously, while such solutions are ongoing, they do not allow for the implementation of additional charging stations or removal of functionality over time without intervening in the core of the system (ie, the system layout), and they limit the possibilities for repair and maintenance of the charging stations themselves.

[0010] Disadvantageously, in known charging systems, if it is desired to increase the number of charging posts or to move charging posts, one has to carry out arduous and expensive additional maintenance operations, such as excavation, construction work and, in particular, wiring.

[0011] According to another disadvantage, current charging systems are inefficient and difficult to expand.

[0012] Documents US2017129353 A1, CN 210363426 U, GB 1413178 A, EP 1950850A1, US2020328604 A1, CN 112224083 A, US2022134901A1, WO 2010120551A1, US2022242262A1, WO 2019147557 A1 show some charging systems and methods related to the problem of transmitting current and charge of vehicles. The solutions described in these documents do not solve the technical problem solved by the present invention.

[0013] In particular, the solution described in the above document has reduced flexibility and does not allow managing the real-time distribution of the current in a modular system.

[0014] The biggest drawback of the prior art systems is that new charging points, new charging columns, cannot be subsequently inserted unless the above mentioned electrical parts are installed again. That is, the addition of future charging columns represents a real further project with respect to the one that already exists, rather than a simple extension of the installed base. Summary of the invention

[0015] Therefore, there is a strongly felt need to provide a modular charging device and current distribution management method that overcomes the typical disadvantages of the prior art.

[0016] In particular, an object of the present invention is to provide a modular charging device which is simpler in construction and manufacture and more versatile than known systems.

[0017] Another object of the invention is to provide a modular charging device, the layout of which is expandable and extendable, retractable or modifiable when necessary, without the need for further installation of power supply components, excavation and construction work, and in particular wiring.

[0018] Another object of the invention is to provide a management method that is efficient and adaptable according to the available power, which management method specifically identifies the scalability of the system and allows its efficient management.

[0019] This need is met by a modular charging device, an installation, expansion and reduction method, a charging method and a current distribution management method according to the appended independent claims. The dependent claims describe preferred or advantageous embodiments of the invention relating to further advantageous aspects. BRIEF DESCRIPTION OF THE DRAWINGS

[0045] The modular charging device 1 also comprises a charging socket 5 connected to said energy supply group 30 and connectable to one or more vehicles 4 to allow supplying electric charge from the energy supply group 30 to such one or more vehicles 4 .

[0046] According to the present invention, the first strip module 11 may be electrically connected to the second strip module 12 including the second conductive strip 26 .

[0047] The technical features described in the present disclosure for the general strip module or for the first strip module are equally valid and applicable to the second strip module or any additional strip modules without loss of generality.

[0048] In an embodiment of the present invention, the modular charging device comprises a plurality of electrically connected adjacent strip modules and one or more charging boxes connected thereto. In another embodiment, the modular charging device comprises only one strip module and one or more charging boxes connected thereto.

[0049] The same applies to the features of the common conductive strips, which apply to the first conductive strip and the second conductive strip as well as the additional conductive strips.

[0050] In other words, the modular charging device 1 comprises a kind of “modular track” including a system of conductive bars for distributing electric power, suitable for supplying one or more charging boxes 3 for electric vehicles 4 .

[0051] Preferably, the modular charging device 1 is suitable for being mounted on a support structure 950 (such as a wall of a building), or mounted on a suspended support structure 950 (such as a base or a bracket). Advantageously, the modular charging device is suitable for a variety of different situations.

[0052] For example, Figure 1 , Figure 2 , Figure 3 and Figure 4 Shown mounted on a wall ( Figure 1 and Figure 3 ), or mounted on a support structure 950 with modular charging devices mounted on both sides to serve two rows of adjacent vehicles ( Figure 2 ), or installed on two walls ( Figure 4 ) four embodiments of a modular charging device.

[0053] Preferably, the busbars 24, 26 support a three-phase system. That is, there are four busbars, one for each phase and one for neutral (ground).

[0054] Preferably, the first and / or second conductive strips 24, 26 are made of metal, such as aluminum or copper.

[0055] Preferably, the first conductive strip 24 and / or the second conductive strip 26 are obtained by extrusion.

[0056] Preferably, the conductive strips 24 , 26 are parallel to each other in the longitudinal extension direction X.

[0057] According to an embodiment, the conductive strips 24, 26 are manufactured to a predetermined length, preferably two meters, preferably three meters.

[0058] Preferably, the conductive strips 24, 26 can be made into different lengths according to application and transportation requirements. For example, the conductive strips are made into a length suitable for storage in containers and transportation devices with standard sizes.

[0059] Advantageously, the modular charging device is expandable and allows its components to be easily transported.

[0060] Preferably, the modular charging device 1 comprises a plurality of charging boxes 3 , which are connected to the conductive bars 24 , 26 via the connection plugs 32 .

[0061] Advantageously, the modular charging device is suitable for receiving a plurality of charging boxes in an electrically connected state and these charging boxes can be positioned at varying points on the longitudinal extension of the conductive strips 24 , 26 .

[0062] Advantageously, the charging box 3 can be connected to the conductive bars 24 , 26 in the longitudinal extension direction X at any point of its longitudinal extension.

[0063] In an embodiment, the modular charging device 1 comprises a second strip of modules 12 adjacent to the first strip of modules 11 in the longitudinal extension direction X. Preferably, the modular charging device 1 comprises a plurality of consecutive second strips of modules 12, which are preferably adjacent to each other.

[0064] The second strip module 12 includes a second conductive strip 26 . Fig.18 An example of an open second module is shown in FIG.

[0065] In an embodiment, Figure 5 , Figure 6 and Fig.10 As shown, for example, the modular charging device 1 comprises an electrical connection device 6 electrically interconnecting the second conductive strip 26 with the first conductive strip 24, thereby allowing the passage of electric current.

[0066] It is clear that the description in the present disclosure about the connection between the first strip module and the second strip module is applicable to the connection between the first strip module or the second strip module and another additional strip module.

[0067] For example, in an embodiment, the modular charging device includes five strip modules, wherein each strip module is mechanically and electrically connected to an adjacent strip module as described for the connection between the first strip module and the second strip module.

[0068] In an embodiment, the first conductive strip 24 includes a first connection end 240 , and the second conductive strip 26 includes a second connection end 260 .

[0069] Preferably, such connection ends 240 , 260 are adapted to be opposite to each other in a connection step between the first strip of modules 11 and the second strip of modules 12 .

[0070] In an embodiment, the electrical connection means 6 comprises, for example Figure 6 , Figure 7 , Figure 8 and Fig. 9 At least one isolator element 62 and at least one connector element 64 are shown in FIG.

[0071] In said at least one isolator element 62 a strip base 621 is provided which is adapted to receive the conductive strips 24, 26 at said first connection end 240 and said second connection end 260 while keeping them spaced apart from each other.

[0072] Preferably, the strip bases 621 are grooves or prismatic depressions and their number is equal to the number of conductive strips per module.Preferably, the strip bases are four parallel grooves in the longitudinal extension direction X.

[0073] The at least one connector element 64 comprises a connecting conductive strip 642 adapted to be inserted in the strip base 621 , at least partially overlapping the first conductive strip 24 and the second conductive strip 26 at the first connecting end 240 and the second connecting end 260 .

[0074] The connecting strip 642 is suitable for contacting and force coupling with the first conductive strip 24 and the second conductive strip 26 to ensure good electrical contact.

[0075] The isolator element is preferably made of a self-extinguishing plastic material.

[0076] Advantageously, the modular charging device 1 can be expanded in the longitudinal extension direction X by simple and intuitive subsequent connection of a plurality of consecutive strip modules.

[0077] This allows avoiding the expensive excavation, installation, wiring, construction work and maintenance operations that are required when expanding the vehicle charging system according to the prior art.

[0078] Preferably, the number of connecting strips 642 is the same as the number of conductive strips of each strip module.

[0079] In an advantageous embodiment, the conductive strips 24 , 26 have a trapezoidal cross section in a plane perpendicular to the longitudinal extension direction X.

[0080] Preferably, the cross section is in the shape of an isosceles trapezoid.

[0081] Alternatively, the cross section is in the shape of a right-angled trapezoid.

[0082] Preferably, the shorter base side of the trapezoid faces the user, ie, towards the front side of the modular charging device.

[0083] In an embodiment, the connecting strip 642 has a trapezoidal cross section on a plane perpendicular to the longitudinal extension direction X, preferably an isosceles trapezoid or a right-angled trapezoid.

[0084] In a preferred embodiment, the cross-section of the connecting strip 642 is a mirror image of the cross-section of the first conductive strip 24 and the second conductive strip 26, so that a geometric force coupling is generated between the inclined surfaces with different inclinations between the connecting strip 642 and the first conductive strip 24 and the second conductive strip 26 in the overlapping portion.

[0085] The term "mirror images of each other" means that in the mounting step, the connecting strip 642 is formed with the shorter base of the trapezoid of its cross section facing the shorter base of the trapezoid of the cross section of the conductive strip.

[0086] In other words, the trapezoidal cross-section of the connecting strip 642 and the trapezoidal cross-section of the conductive strips 24, 26 are inverted, ie, in the installed condition, the conductive strips 24, 26 and the connecting strip 642 overlap in a "ramp" manner, thereby producing an optimal pressure contact.

[0087] Advantageously, the above-mentioned trapezoidal cross section ensures an optimal electrical connection by generating pressure with a so-called "wedge-shaped" insertion. Such an embodiment allows obtaining an electrical connection while avoiding the use of elastic elements which could impair the contact quality over a long period of operation.

[0088] In a preferred embodiment, the cross-section of the connecting strip 642 has rounded edges to facilitate sliding of the connecting strip 642 over the conductive strips 24 , 26 .

[0089] In an embodiment, the conductive strips 24, 26 also have a cross-section with rounded edges.

[0090] In an embodiment, the connector element 64 comprises a closing plate 641 made of an insulating material (preferably a self-extinguishing insulating material), which comprises an insulating prismatic portion 640 which protrudes from the closing plate 641 and comprises a strip base in which the connecting conductive strip 642 is joined.

[0091] Preferably, the prismatic portion 640 has a preferred extension in a direction orthogonal to the connecting strip 642. The prismatic portion serves the function of keeping the connecting ends 240, 260 longitudinally spaced apart from each other.

[0092] In an embodiment, the isolator element 62 has a prismatic coupling base 620 which geometrically engages with said prismatic portion 640 of the connector element 64 .

[0093] In other words, the isolator element 62 is a supporting base that receives the conductive strips 24, 26 from the back (i.e., in one embodiment, on the side of the longer bottom side of the trapezoid), keeping them spaced apart and parallel to each other, and the connector element 64 is a cover with connecting strips (and thus conductive strips) that is suitable for acting as a bridge for passing current between the first conductive strip 24 and the second conductive strip 26.

[0094] Preferably, when installed, the joint element 64 is securely fastened to the isolator element by external fasteners (eg, screws or pins).

[0095] Preferably, the connecting conductive strips 642 are engaged in the strip base of the prismatic portion 640 in a manner spaced apart from each other and protruding.

[0096] Preferably, the closing plate 641 and the prismatic portion 640 are made of a self-extinguishing plastic material.

[0097] Preferably, the connecting strips are made of aluminium or copper. Preferably, they are part of the conducting strips. Preferably, they are part of a metal extrusion.

[0098] In an embodiment, at least one of the first strip module 11 and the second strip module 12 comprises an isolator 7 made of insulating material, which is suitable for keeping the first conductive strip 24 and / or the second conductive strip 26 spaced apart and substantially parallel to each other when they extend along the longitudinal extension direction X.

[0099] Preferably, for example, the first module 11 and the second module 12 both include an isolator 7, such as Figure 5 and Fig.11 As shown in the embodiment of FIG.

[0100] In an embodiment, the strip modules 11 , 12 comprise a series of spacers 7 placed at equal and predetermined distances from each other.

[0101] In the embodiment, the isolators 7 each include a first rear isolator portion 71 and a second front isolator portion 72 .

[0102] Each of such first and second isolator parts 71 , 72 has a respective groove 710 , 720 , the main extension direction of each groove being parallel to the longitudinal extension direction X.

[0103] The first isolator portion 71 and the second isolator portion 72 are mutually engageable (engaged) such that the respective recesses 710, 720 match to form a seat suitable for engaging the first conductive strip 24 and / or the second conductive strip 26 by form coupling.

[0104] Preferably, the base has a trapezoidal cross section, even more preferably an isosceles trapezoidal or right-angled trapezoidal cross section.

[0105] In other words, the matching grooves due to the engagement between the isolator parts form a seat having a cross section in a plane perpendicular to the longitudinal extension direction X so as to receive and block the conductive strips 24 , 26 .

[0106] Preferably, the first isolator portion 71 may be fastened to the second isolator portion 72 by pins or screws.

[0107] In an embodiment, at least one of the first strip module 11 and the second strip module 12 includes a housing 21, 22 encapsulating the first conductive strip 24 and / or the second conductive strip 26. For example, Fig.18 and Fig. 20 The housing is shown in the embodiment of FIG.

[0113] According to the advantages of the present invention, Fig. 20 As shown, the socket base is arranged at any point of the longitudinal extension part of the housing 21, 22 along the longitudinal extension direction X.

[0114] Advantageously, the use of conductive strips allows providing a base (and socket) for connecting a charging box at any point in the longitudinal extension of the modular charging device.

[0115] This brings increased flexibility to the modular charging device and allows the user to easily modify the installation layout of the modular charging device as needed.

[0116] In the present disclosure, the term "front" or "front" or "front part" refers to a plurality of components that are on the user side (i.e., on the side of the track intended for attaching the charging box) relative to the conductive strips in the modular device. Vice versa, the term "rear" or "rear" refers to a component that is on the side opposite to the user (e.g., toward the wall to which the track is mounted) relative to the conductive strips in the modular device.

[0117] In an advantageous embodiment, the housing 21, 22 comprises:

[0121] In an embodiment, the isolator element 62 is fastened to the rear profile 211 , 221 of the housing 21 , 22. Thereby, the isolator element serves as a supporting element for the conductive strips 24, 26.

[0122] In an advantageous embodiment, the rear profiles 211 , 221 are metal profiles having a “C”-shaped cross section in a plane orthogonal to the longitudinal extension direction X.

[0126] In an advantageous embodiment, the socket base is arranged in the front profile 212 , 222 .

[0127] In the examples and with reference to Fig.15 and Fig.17 The isolator 7 includes one or more load-bearing isolators 701, which are at least partially fastened to the shells 21, 22 so as to support and keep the first conductive strip 24 and the second conductive strip 26 suspended, and keep the first conductive strip and the second conductive strip integrated with the shells 21, 22.

[0128] Preferably, if Fig.18 As shown, for example, such one or more load-bearing isolators 701 are at least partially fastened to the front profile members 212 , 222 .

[0129] Even more preferably, the second isolator part 72 is fastened to said front profile 212, 222. Preferably, the fastening is by snap connection, bayonet connection, gluing or by screw fastening.

[0130] Such an embodiment advantageously allows "prefabrication" of a portion of a modular charging device, comprising at least a front profile of a shell supported by a load-bearing isolator and a conductive strip, and minimizes on-site installation operations for extending the modular charging device, which on-site installation only involves electrical coupling between the additional strip module and the already installed strip modules (by means of electrical connection through the aforementioned electrical connection device), and possibly fastening the front profile to the rear profile of the shell.

[0131] In the embodiment, the isolator 7 comprises only auxiliary isolators 702 which are exclusively engaged in the first conductive strip 24 and / or the second conductive strip 26 and are independent of the housing 21 , 22 , i.e. separate from the housing, detached from the housing, and autonomously exist relative to the housing.
