Description

Title of the invention: Electric charging system for electric vehicles, preferably heavy vehicles, and corresponding method FIELD OF THE INVENTION

[0001] The present invention relates generally to an electric charging system for electric vehicles, preferably heavy vehicles, and a corresponding method. PREVIOUS ART

[0002] For example, on a parking infrastructure intended for loading / unloading equipment into heavy goods vehicles, heavy vehicles, also called heavy goods vehicles, are usually parked in reverse so that their rear loading area is opposite a corresponding loading and unloading access area of ​​the infrastructure.

[0003] Electric heavy goods vehicles have charging connectors located at the front of the vehicle. This poses problems when equipping car parks with electric charging stations for heavy goods vehicles because the maximum length of the cable coming from the station and used for electric charging is normally 10 meters.

[0004] The terminals cannot therefore be installed on sidewalks or in the loading and unloading access area at the rear of the vehicle.

[0005] It is known from the state of the art to install electric charging terminals between two heavy vehicle parking spaces, preferably in a position close to the location of the front cabin of the heavy goods vehicle equipped with the charging connector when the heavy vehicle is parked in reverse.

[0006] However, this first solution generally results in a significant footprint for the rapid electric charging stations, which is often accompanied by a loss of parking spaces. There is also a risk of collision between the heavy goods vehicle and the station when the heavy goods vehicle is reversing.

[0007] It is also known from the state of the art to install gantries allowing part of the equipment to be suspended.

[0008] The disadvantages of this second solution include a high installation cost, and the need to provide concrete blocks on the ground to support the metal structure.

[0009] In addition, this type of massif often requires geotechnical studies in order to validate the strength of the whole, which increases the cost of the solution and makes it more long to deploy.

[0010] The problems of congestion and the risk of damage to the terminals also arise for parking infrastructures for other types of electric vehicles, such as buses.

[0011] The present invention aims to propose a new system and method making it possible to overcome at least some of the problems set out above. Summary of the invention

[0012] To this end, the invention relates to an electric recharging system for electric vehicles, preferably heavy vehicles, the system comprising: - a power cabinet comprising: a power conversion system connectable to a three-phase electrical mains, the power conversion system being configured to deliver a direct current, a power distribution module; - electric charging devices, called rapid charging points, for the electric charging of vehicles, each rapid charging point comprising: an electronic management system; a charging cable fitted at one end with a charging connector, preferably type CCS2, each fast charging point being connected to the power cabinet by a power cable and a communication cable; characterized in that the charging system comprises, for each rapid charging point, a wheel guidance device; at least the electronic management system of each rapid charging point is housed in a box which has at least one entry hole for the power cable and the communication cable, the top of the box being located at a height less than or equal to the height of the top of the wheel guide device, and in that, the charging cable being movable between a stowed position waiting for use, and a position of use to be connected to a corresponding connector of an electric vehicle, the charging cable is, in the stowed position waiting for use, located at a height less than or equal to the height of the top of the wheel guidance device.

[0013] Thus, when a vehicle parks in a parking space for rapid recharging, the part of the vehicle overhanging the axles can pass over the box and the recharging cable without touching said box or said cable.

[0014] Such a system design makes it possible to equip heavy goods vehicle parking lots with fast charging stations for which the risk of damage is reduced.

[0015] Providing a main cabinet makes it possible to group together components, in particular bulky components, in particular the AC / DC power conversion system, and the current distribution module, to install them in a less constrained area, away from the locations where heavy vehicles are intended to park, in particular in a remote manner relative to the fast charging stations which, conversely, are located closer to said parking locations to allow proximity between the fast charging station and an electrical connector of the heavy goods vehicle, in the parked state of the latter in order to facilitate the connection of the connector of the charging cable of a fast charging station with the corresponding electrical connector of the heavy goods vehicle.

[0016] The fast charging terminals can thus be located as close as possible to the vehicle's charging connector. In particular, the fast charging terminal can be located less than ten meters from the position occupied by the heavy goods vehicle's connector when the heavy goods vehicle is parked in reverse gear in its location, the heavy goods vehicle's connector being located at the front.

[0017] The charging cable may be protected by the wheel guidance device (wheel guide) by being, in the stored state, housed in the wheel guidance device or between two elements of the wheel guidance device. It may also be provided that the box is housed at least partly in the wheel guidance device and / or between two elements of the wheel guidance device to be protected by the wheel guidance device. It may be provided that the box is buried or partially buried.

[0018] The system may also include one or more of the following features taken in any technically admissible combination.

[0019] According to one embodiment, the box is located, in top view, between elongated elements, preferably parallel to each other, of the wheel guidance device, said elongated elements being called maneuvering aid devices, such as tubes or concrete curbs. In other words, the box is located in top view in the space delimited by the elements of the wheel guidance device.

[0020] The elements of a wheel guide delimit between them a space which is not used for positioning the vehicle and which can therefore be used to position a terminal box between the wheel guide elements without the space taken up by the box being to the detriment of the useful parking areas of the vehicles. The elements of a wheel guide may comprise two elongated elements which extend parallel to each other and at a distance from each other. The elements of a wheel guide may also comprise a front element which extends from one of the elongated (lateral) elements towards the other to at least partially close access to the area delimited between the two parallel elongated elements.

[0021] According to one embodiment, the system comprises a device for storing the charging cable outside the box.

[0022] According to one embodiment, the system comprises a charging cable storage device positioned in at least one element of the wheel guidance device or between the elements of the wheel guidance device.

[0024] According to one embodiment, the storage device is provided in an elongate element of the wheel guide device, preferably in the form of a channel or groove provided in and along said elongate element of the wheel guide device. In other words, the storage device can be integrated into the wheel guide device.

[0025] According to one embodiment, the device for storing the charging cable is arranged in or on the ground, for example in the form of a channel or groove arranged in the ground and preferably along an elongated element of the wheel guide device.

[0027] According to one embodiment, the storage device comprises a member for receiving and holding the connector of the charging cable.

[0028] The retention can be achieved by shape cooperation of the connector with a support, or by an activatable / deactivatable retention mechanism to maintain or release the connector of the charging cable relative to a support.

[0029] According to one embodiment, the system comprises a cable gland device which forms a connection between the box and the outgoing part of the charging cable relative to the box to guide the charging cable.

[0030] According to one embodiment, the wheel guidance device has a top with a height of between 20 cm and 40 cm (relative to the ground on which the guidance device is fixed).

[0031] According to one embodiment, the box is at least partially buried.

[0032] According to one embodiment, the current distribution module is configured to direct an electrical power of at least 100 kW, from the power conversion system to one or more of the rapid electrical charging points, to enable the or each of said rapid charging points to deliver a power of at least 100 kW to the corresponding vehicle.

[0033] The power conversion system thus makes it possible to deliver, via the distribution module current supply, a direct current of at least 100 kW for each fast charging point, said or each of said fast charging points being capable of delivering a direct current of at least 100 kW to an electric vehicle whose charging connector is connected to said fast charging cable of the corresponding fast charging point.

[0034] According to one embodiment, wherein the electronic management system is housed in a housing to form an electronic housing which is housed in the cabinet.

[0036] Preferably, the wheel guidance device comprises an elongate element which has a groove formed in and along said elongate element inside and along which the charging cable is stored in a position ready for use.

[0037] The power cabinet is intended to be powered by being connected to a three-phase electrical sector.

[0038] According to one embodiment, the method comprises placing the box, seen from above, between elements, preferably elongated, of a wheel guidance device fixed to the ground, said elements, preferably parallel to each other, being called maneuvering assistance devices, such as tubes or concrete curbs.

[0039] According to one embodiment, the method comprises placing the box between elongated elements, preferably parallel to each other, of a wheel guidance device fixed to the ground, said elongated elements being called maneuvering aid devices, such as tubes or concrete curbs. The box can be located on the side of a front element of the wheel guide device, in the space delimited between the elongated elements and the front element which extends from one of the elongated elements towards the other elongated elements.

[0040] According to one embodiment, the charging method also comprises the following steps: - positioning a vehicle, preferably in reverse, in a parking space with passage of a part of the vehicle, which is cantilevered in relation to the axles of the vehicle, above the box; - finalizing the positioning of the vehicle along said location (in other words along the wheel guidance device), the vehicle being moved horizontally away from the rapid charging point; - connection of the charging cable connector to the vehicle's electrical connector to recharge the vehicle's battery.

[0041] According to one embodiment, in the stored position waiting for use, the charging cable is housed inside and along a groove provided in an elongated element of the wheel guide device, said groove having an opening opposite the bottom of the groove which is preferably oriented upwards, to facilitate storage and grasping of the charging cable by a user.

[0054] Embodiments are described below with reference to the accompanying drawings. Similar numerals refer to similar elements throughout the drawings. However, the invention may be embodied in many different forms and should not be construed as being limited to the embodiments set forth herein. The scope of the invention is defined by the appended claims.

[0055] A reference throughout the specification to "an embodiment" means that a particular functionality, structure, or characteristic described in relation to an embodiment is included in at least one embodiment of the present invention. Thus, the appearance of the expression "in an embodiment" at various locations throughout the specification does not necessarily refer to the same embodiment. Furthermore, the particular functionalities, structures, or characteristics may be combined in any suitable manner in one or more embodiments. With reference to the figures, there is provided an electric charging system (or installation) 1, called fast, for electric vehicles 5, preferably heavy electric vehicles.The electric charging system 1 comprises a power cabinet 2 and fast charging devices 3, called fast charging terminals or points, for charging heavy vehicles. The power cabinet 2 is common to the fast charging devices 3 and makes it possible to group together in said cabinet and therefore to move bulky components of the system away from said fast charging devices 3. The power cabinet 2 can be considered as a central element of the system and the fast charging devices 3 can be considered as satellites of the central element.

[0056] The configuration of the electric charging system 1 makes it possible to limit the risk of degradation of the system, in particular the risk of degradation of the rapid charging devices 3, while maintaining sufficient space for the parking spaces of the heavy electric vehicles 5.

[0057] With the electric charging system 1 according to the invention, when a vehicle, in particular a heavy vehicle, is parked in a parking space in an area equipped with the charging system, the heavy electric vehicle 5 can be electrically recharged easily for the user and without risk of shock between the vehicle and the rapid charging devices 3.

[0058] Power cabinet

[0059] As mentioned above, the production of the electric charging system 1 in the form of a power cabinet on the one hand and several rapid charging devices 3 on the other hand, makes it possible to relocate a bulky part of the system formed by said power cabinet 2 at a distance from the devices, preferably in an area away from the vehicle maneuvering range.

[0060] It is understood in fact that, if the rapid charging devices 3 need to be positioned sufficiently close to the vehicle locations 50 for being able to connect the charging connector of the cable of the fast charging device 3 to the corresponding connector of the vehicle, conversely, the power cabinet 2 which is connected to the fast charging devices 3 by power cables 4, can be remote from the vehicle locations 50, for example on a sidewalk.

[0061] The power cabinet 2 comprises a power conversion system 21 connectable to the three-phase AC electrical sector of the site by a power input cable 211. The power conversion system 21 comprises one or more power conversion modules, for example depending on the voltage that is desired to be delivered and / or for reasons of reliability, redundancy or availability. The power conversion system 21 is configured to be able to convert the alternating current AC into direct current DC. The power cabinet 2 also comprises a current distribution module 22, such as a set of relays, configured to direct the power supplied by the power conversion system 21 to the fast electrical charging devices 3.

[0062] Preferably, the power conversion system 21 is configured to be able to deliver a direct current DC of at least 100 kW, for example 150 kW, to each electric charging device 3.

[0063] A control unit 23 (or control module) makes it possible, in cooperation with an electronic management system of each electric charging device 3 presented below, to control the supply of power to each electric charging device 3 and the communication with the electric charging devices 3. In particular, the control unit 23 ensures the concordance between the unit power demands of each charging point (electric charging device 3) and the total available power that the power cabinet (in particular the power conversion system 21) can supply.For example, it is possible to provide that the installation comprises eight 150 kW charging points connected to a 1000 kW power cabinet so that the control unit 23 controls the distribution of power between the charging points according to the power requested by the charging points and the power available at the power cabinet.

[0064] Fast charging devices

[0065] Each fast charging device 3 comprises an electronic management system 30A. The electronic management system comprises a control unit for communicating with the control unit of the power cabinet. The fast charging device 3 also comprises a charging cable 32 connected to the electronic management system 30A and provided at one end with a charging connector, preferably of the CCS2 type.

[0066] As explained previously, the electronic management system of the rapid charging device 3 communicates with the control unit 23 of the power cabinet.

[0067] Each fast charging device 3, in particular the electronic management system 30A, is connected to the power cabinet 2 by a power cable 4. Each fast charging device 3, in particular the electronic management system 30A, is also connected to the power cabinet 2 by a communication cable 4'.

[0068] At least the electronic management system 30A is housed in a box 7. The electronic management system 30A is preferably housed in a housing 30, to form an electronic box which is itself housed in the box 7. It may be provided that the box 7 and / or the box 30 is waterproof. It may also be provided that the box 30 is waterproof and that the box 7 has a connection orifice to the sewer.

[0069] Box

[0070] According to one embodiment of the invention, the box 7 is located, in top view, between elongated elements 61 of a wheel guide device 6 fixed to the ground.

[0071] The ground reference S0 used, i.e. the zero height level, can be considered as being the ground level to which the wheel guidance device is fixed or the ground level on which the vehicle is positioned in the parked state on a parking space which extends next to a wheel guidance device 6.

[0072] According to one embodiment, the wheel guidance device has a vertex S6 located at a distance of between 20 cm and 40 cm from the ground S0.

[0073] As mentioned above, the box 7 may be configured to be watertight, for example by sealing lips. It may also be provided that the box 7 has a connection orifice to the sewer.

[0074] Preferably, the box 7 comprises a closing cover 71 that can be opened and closed. It may be provided that the box is arranged so that, in the closed state of the cover 71 which closes access to the interior of the box 7, the cover 7 of the box 7 is flush with or extends below the ground. In other embodiments, the cover forming the top of the box extends above the ground but to a height less than or equal to that of the wheel guide device 6.

[0075] According to an embodiment not illustrated, in which the cable can be stored in the box, it can be provided that a support element for the charging cable is fixed to the cover 71 of the box 7. It can be provided that opening the cover causes the connector of the charging cable to come out at least partially from the inside of the box, which makes the connector of the charging cable accessible to the user who can thus grasp it to connect it to the corresponding connector of the electric vehicle to be recharged.

[0076] Wheel guidance device

[0077] Said elongated elements 61 are called maneuvering assistance devices. The elongated elements 61 preferably extend parallel to each other and at a distance from each other.

[0078] It may also be provided that the wheel guide device 6 comprises a front element 62 (see for example [Fig.2]) which at least partially closes the entrance to the passage delimited between the lateral elongated elements 61. Said elongated elements 61 (as well as the front element 62) may comprise tubes, as in the example of Figures 2 to 3C, 4, 6 and 7 or concrete borders, as in the example of Figures 3D and 8.

[0079] According to one embodiment, each maneuvering assistance device 61 has a top located at most 40 cm from the ground S0, and at least 20 cm from the ground ([Fig.5]).

[0080] Ground S0 means the reference ground corresponding to the vehicle's driving area. The vehicle's location area is thus part of ground S0.

[0081] As shown diagrammatically in [Fig.5] and in connection with Figures 6 and 7, the top S7 of the box 7, which is located at a height less than or equal to the top of said elongated elements 61, is thus located at a height less than or equal to 40 cm relative to the ground S0, so that, when a vehicle 5 parks in a location 50 for rapid recharging, the top S7 of the box 7 allows the part 51 of the vehicle in overhang to pass above the box 7.

[0082] Charging cable storage

[0083] According to a preferred embodiment, the system comprises a storage device 9 for the charging cable outside the box 7.

[0084] As illustrated in Figures 3A to 3D, and in Figures 6 to 8, the storage device 9 may be arranged in an element of the wheel guidance device 6, for example in the form of a channel or groove arranged in and along an elongate element of the wheel guidance device, such as a concrete tube or curb. Advantageously, the storage groove for the charging cable is arranged in and along an elongate element 61 of the wheel guidance device, along which the vehicle is intended to be positioned in the parked state on the corresponding parking space. Preferably, the groove is open upwards to allow the cable to be easily stored by depositing it by gravity in the groove which forms the storage device 9.

[0085] Alternatively, the storage device 9 for the charging cable may be provided in or on the ground, for example in the form of a channel or groove provided in the ground and along an elongated element of the wheel guide device 6, as illustrated for example in [Fig.2].

[0086] According to a particular aspect, the storage device 9 comprises a member for receiving and holding the connector of the charging cable.

[0087] The system may comprise a cable gland device which forms a connection between box 7 and the outgoing part of the charging cable 32 relative to box 7 for guide the cable.

[0088] As illustrated in [Fig.4], according to another embodiment, it can be provided that the system comprises a reel (not shown) allowing the cable to be wound around a vertical axis.

[0089] Method

[0090] A method is proposed below for setting up a system as proposed above on a parking site for electric vehicles, preferably heavy vehicles, such as heavy goods vehicles.

[0091] The site has several parking spaces 50 each associated with at least one wheel guidance device 6. A wheel guidance device 6 may be arranged between two parking spaces 50, or at one end of the plurality of parking spaces. Similarly, a parking space located between two other parking spaces may be arranged between two wheel guidance devices, and an end parking space may be associated with a single wheel guidance device or be located between two wheel guidance devices.

[0092] The wheel guidance device comprises elements, preferably elongated, which delimit between them a space in which the box can be positioned and protected, without the box encroaching on a parking space. The charging cable can also be protected by being stored inside said space or inside an element of the wheel guidance device.

[0093] The method comprises the following steps. The power cabinet 2 is installed on the parking site, preferably at a distance from the parking spaces 50, for example on a sidewalk. The power cabinet 2 is connected by the cable 211 to a source of three-phase alternating current AC.

[0094] The rapid charging devices 3 are preferably installed between two parking spaces 50, each being associated with a wheel guidance device.

[0095] Each fast charging point 3 is connected to the power cabinet 2 by a power cable 4 and communication cable 4'.

[0096] The electronic management system 30A, preferably housed in a housing 30 to form an electronic housing, of each rapid charging point 3 is housed in a corresponding box 7 which has at least one entry orifice 74 for the power cable 4 and the communication cable 4'.

[0097] According to one embodiment, the method comprises placing the box 7 between elongated elements 61 of a wheel guidance device 6 fixed to the ground (in top view), said elongated elements being called maneuvering assistance devices, such as tubes or concrete curbs.

[0098] According to one embodiment, the method comprises at least partial burial of the box 7. Box 7 can also be completely buried.

[0099] The top S7 of the box 7 is located at a height less than or equal to the top of the wheel guide device 6, i.e. at a height less than or equal to 40 cm from the ground, so that, when the vehicle is parked for rapid recharging, the part 51 of the vehicle 5 in overhang can pass above the box 7.

[0100] The charging cable 32 of the rapid charging point 3 may be protected by the wheel guidance device (wheel guide) by being, in the stored state, housed in the wheel guidance device, in particular in a channel or groove provided in an elongated element 61 of the wheel guidance device or between two elongated elements of the wheel guidance device. It may also be provided that the box is housed at least partly in the wheel guidance device and / or between two elements of the wheel guidance device to be protected by the wheel guidance device.

[0101] To park, the vehicle 5 can pass partly 51 above the box 7, as illustrated for example in [Fig.6]. In the parked state, the vehicle 5 no longer has a part above the box 7, as illustrated for example in [Fig.7] or 8.

[0102] The user can then grasp the charging cable 32 from the terminal 3 located on the side of the truck which has a battery charging connector, to remove the charging cable 32 from its storage 9, for example by removing it from a groove provided in an elongated element 61 of the wheel guide device 6. Then the user can connect the connector of the charging cable 32 to the corresponding connector of the vehicle in order to recharge the vehicle battery. As explained previously, the control unit 23 of the cabinet communicates with the control unit of the electronic management system 30A of the electric charging device 3, to control the supply of power necessary for the electric charging device 3 to enable the vehicle battery to be recharged.

[0103] Once recharging has been carried out, the cable can be stored in its housing, for example by being deposited by gravity in and along the groove provided in the elongated element 61 of the wheel guide device 6.

[0104] Plug-in electric vehicles

[0105] Preferably, the electric vehicles rechargeable using the system include all or part of the following vehicle categories: Category designation - Authorized Total Weight (ATW) N2: from 3.5 Tonnes up to 12 Tonnes N3: greater than or equal to 12 Tonnes 03: from 3.5 Tonnes up to 10 Tonnes 04: greater than or equal to 10 Tonnes M2: PTAC less than 5 tonnes for a vehicle configuration including a driver's seat and more than 8 passenger seats M3: greater than or equal to 5 Tonnes for a vehicle configuration including a driver's seat and more than 8 passenger seats; where N, O and M correspond to the following three types of categories: N: Motor vehicle used for the transport of goods: Tractor / Carrier O: Towed vehicle used for the transport of goods: Semi-trailer / Trailer M: Public Passenger Transport Vehicle: Motorhome / TCP (Public Passenger Transport)

[0106] The control unit of the electrical cabinet and / or of each rapid charging device is for example in the form of a processor and a data memory in which computer instructions executable by said processor are stored, or in the form of a microcontroller.

[0107] In other words, the functions and steps described in connection with the cabinet and the fast charging point can be implemented in the form of a computer program or via hardware components (e.g. programmable gate arrays). In particular, the functions and steps operated by the control units can be carried out by instruction sets or computer modules implemented in a processor or controller or be carried out by dedicated electronic components or components of the programmable logic circuit type (or FPGA which is the acronym for field-programmable gate array, which literally corresponds to in-situ programmable gate array) or of the application-specific integrated circuit type (or ASIC which is the acronym for application-specific integrated circuit, which literally corresponds to application-specific integrated circuit).It is also possible to combine computer parts and electronic parts.

[0108] The invention is not limited to the embodiments illustrated in the drawings.

[0109] Furthermore, the term "comprising" does not exclude other elements or steps. Furthermore, features or steps that have been described with reference to one of the embodiments set forth above may also be used in combination with other features or steps of other embodiments set forth above.
