Description

The invention relates to an electric vehicle charging terminal, installed in an outdoor environment. It comprises a fixed base and a sealed door, in particular closed by a high-force mechanism which is closed by a security lock. The electrical, electronic and cooling components of the terminal are distributed both on the inner surface of the base and on that of the door, allowing better accessibility. The door represents most of the periphery of the terminal, which improves the accessibility of the base components. The terminal further includes a removable head carrying the user interface and the digital processors. It also includes a cooling system including a sealed air recirculation internal circuit, cooled by a heat exchanger bathed in an open outdoor air circuit. The terminal includes a charging cable with a movable connector which is stored in an electrically controlled locking receptacle.

STATE OF THE ART There are charging stations that are installed in various types of environment with little or no protection, provided to be able to easily recharge storage batteries of mobile electrical appliances, for example electric vehicles. These may include, for example, recharging terminals for electric vehicles, for example cars or utilities in an urban environment, but also forklifts within a factory or a logistics base. It can also be smaller devices, for example to charge bikes or mobile phones. Such terminals are generally powered by an electrical distribution network, typically low voltage alternating current between 380V and 110V. It includes the electrical circuits necessary for 3034615 - 2 - providing devices to recharge a current adapted to the characteristics of the storage battery, also called accumulators, whether chemical storage or supercapacitors. The same terminal may be able to provide a charging current under several different standards, possibly simultaneously. This charging can be done, for example, DC 5V, 14V or 48V under 10A for portable batteries, or for example 220V DC or AC 16A for urban electric vehicles. More particularly, charging stations are installed in a static manner in order to allow a non-technical user to connect his own device to recharge the storage battery, also called accumulators, whether chemical storage or even supercapacitors. Such terminals are thus designed to allow simple and secure operation, without the risk of an electrical accident and limiting the risk of connection errors. They are often located in a little or no protected environment, for example in a station or airport hall or directly outside on the public road or at the edge of a street open to motor traffic. They must be adapted to harsh environments, resist corrosion and deterioration, especially depending on the climate. They must be suitable for intensive use, many charging and / or discharging cycles, heating and aging, etc.

The access to recharging is sometimes controlled and secured, for example to check the rights of the user, for example by means of an interactive controller and / or an electronic or optical badge reader which controls the power supply of the charging circuit. and / or the accessibility of the electrical charging connector. The terminal can be controlled remotely, for example to record the status of presence and load of the network vehicles and know the operating status of the terminal. WO 2010/011545 discloses for example a terminal provided with an upward flap which houses a fixed grip. The shutter can be locked on the side by an electrically controlled rod.

For example, for a rental network or provision of self-service electric vehicles in an urban environment, self-service charging stations are distributed in numerous locations in a city. Maintenance operations are therefore all the longer and more expensive.

On some models, the terminal has a fixed socket providing the charging current when an electric vehicle owner plugs in the cable of his vehicle. In particular, the terminal has a housing protected by a lockable cover, in which can be stored a charging cable that the user can connect between the terminal and his vehicle, when the vehicle does not have its own cable. An object of the invention is to improve the existing terminals, for example by improving their reliability of operation and safety, their ease and their period of maintenance, planned or on demand, and by decreasing the various costs concerned. In particular, it is desired an improvement in the operation of the locking of the socket on the terminal, the reliability of the locking and the opening and closing of the protective cover of the socket and / or the cable housing.

These improvements are sought while maintaining or improving the protection of the terminal and its environmental resistance, for example to heat, humidity and dust. It is also sought to maintain or improve the protection of the terminal against damage and users or bystanders against the risk of injury from the terminal.

SUMMARY OF THE INVENTION The invention proposes a recharging terminal for an electric storage battery, in particular for electric vehicles, which is intended to be fixedly implanted in an unprotected environment, in particular accessible to the public. even outside and for example on roads. Such a terminal is of the type comprising a set of electrical, electronic and cooling components, including a charging circuit, which are enclosed within an outer wall forming an outer protective enclosure. This enclosure also optionally includes various mechanical or electromechanical components involved in the operation of the terminal. This set of components typically comprises components providing a charging power supply adaptation, an electronic management of this power supply and its use, a cooling of all or part of the electrical and / or electronic components, and optionally an access to a power supply. electric cable provided to make the connection with a device whose battery must be charged. Preferably, this outer protective enclosure is waterproof and dustproof. According to the invention, such a terminal comprises: on the one hand, at least one fixed part forming a static implanted base and which has at least one so-called inner surface directed towards the inside of the protective enclosure, on which is implanted at least a first part of said components; and on the other hand, at least one movable part articulated on said base to form a door which has at least one so-called inner surface directed towards the inside of the protective enclosure, on which at least a second part is implanted said components. This door is arranged to be movable between at least: - a closed position, wherein said door forms part of the outer protective enclosure and obstructs access to said inner surfaces; and an open position, wherein said door allows access, including control and maintenance, to said inner surfaces. For example, the terminal comprises two parts articulated with respect to each other, so as to form a column, in particular of revolution and for example circular. This column has a fixed part including its base and constituting the base, and which represents less than half, and preferably substantially one third of the volume of the terminal. Viewed from the outside, the door comprises a portion (31) of the outer wall of the terminal which forms for example a cover or an opening of any type articulated in the front of the terminal. Preferably, this door represents in the invention at least half and for example substantially two-thirds of the periphery of the terminal. Thus, the opening of the door not only makes it possible to release access to the components fixed inside the base, but also to move outside the terminal all the components that are implanted in or on the inner surface. Door. It is thus possible to access a much greater number of components much more easily than in the case of a simple opening panel, such as a simple sheet, which gives access to the interior of the enclosure. For example, the components discovered by the door are located mostly on the base, and are thus all the more accessible. According to a feature of the invention, which can be implemented independently of the others, this terminal comprises a locking mechanism of the door in the closed position comprising at least, on the one hand, a lock and lock, on the other hand, a lock of prohibition. This locking lock comprises one or more mobile bolts between at least one released position allowing the opening of the door and a locked position in which said bolts support a holding force applied between said door and the base, typically the entire door. effort to keep the door. Said bolts are actuated by at least one form of maneuver accessible from outside the terminal by at least one maneuvering orifice, that is to say a shape having a large and solid bearing surface, preferably one-piece , and without moving parts or antitheft or anti-picking mechanism such as single code or key profile. The prohibition lock includes a mechanism prohibiting opening, that is to say, prohibiting an unauthorized person, for example a known type such as a lock barrel. When actuated, this prohibition mechanism moves a shutter between at least one shutter position, in which it closes the operating orifice, preferably in a dust and watertight manner, and retracted position, in which it allows access to the form of maneuver from the outside through said maneuvering orifice. It is thus possible to provide a significant support force between the door and the base once the terminal closed, and thus to obtain a better seal for example with a seal better squeezed. This advantage is obtained while ensuring a good ban on unauthorized persons and while protecting the form of maneuver from deliberate damage and the environment by concealing and sealing its access opening.

According to another feature of the invention, which can be implemented independently of the others, the terminal has an elongated shape having an upward end forming, partially or in its entirety, a removable head which is fixed to the base by a hooking mechanism. This mechanism is of a type, for example known, that can be actuated between at least one hooked position, in which it keeps said head integral with the base, and a released position, in which said head is entirely detached from the base. According to the embodiments, this mechanism can be operated in a single operation, or possibly in several operations that can include a connection or disconnection of different electrical and / or electronic connection sockets. Preferably, at least a third portion of the terminal components, including a user interface and / or a digital processing processor, is located on or integrated into the removable head.

It is thus easier to access these components, but also to replace them or take them all away, and without separating them from each other. The terminal can thus more easily be repaired immediately by replacing the head as a whole, and report it to the workshop for example for repair and / or hardware update and / or software. According to another feature of the invention, which can be implemented independently of the others, the terminal comprises at least one electric charging cable which is fed by the charging circuit, typically at one end, by a connection inside the terminal; and which carries outside of the terminal, typically at its other end, a connecting portion of a mobile connector adapted to be connected to a battery to be recharged or to an apparatus containing a battery to be recharged.

According to this feature, the outer wall carries a receptacle which is made one-piece or forms an integral assembly which can be detached or disassembled from said outer wall in one piece. This receptacle comprises: on the one hand, a guide orifice through which said cable passes through the outer wall and moves axially to be extracted from or retracted inside the protective enclosure, and on the other hand , a shape arranged to allow to hang the connecting portion of the movable connector in a standby position. Thus, the receptacle forms an assembly which provides all external functions related to the charging cable, and is replaceable in one piece. According to one feature, the receptacle is further covered by a plate or a metal foil wholly or partly conforming to the surface of the interior and the periphery of the guide orifice.

For example, the movable connector receptacle is carried by the terminal door and the electric charging cable is wound inside the terminal on an automatic or electrically rewindable reel, which reel is implanted on a surface. inside the door or integrated with it.

This functional assembly, including the reel and the loading cable itself, is thus entirely located in and fixed on the movable part of the terminal. The compactness is improved and this greatly frees access to the interior of the terminal during opening. In addition, it is thus possible to disassemble and replace all of this mobile part 3034615 - 8 - and thus the entire charging cable and its rewinding mechanism, to ensure a quick repair and bring it back to the workshop for more complete work. According to another feature of the invention, which can be implemented independently of the others, the terminal comprises at least one electric charging cable which is fed by the charging circuit, typically at one end, by a connection located inside the terminal, and which carries outside the terminal, typically at its other end, a movable connector intended to be connected to a rechargeable battery or to an apparatus containing a battery to be recharged. According to this feature, the outer wall carries a receptacle which comprises a shape arranged to receive a connecting portion of a movable connector in a waiting position. The outer wall further carries a connector locking mechanism which can be actuated by electrical control between at least: - a released position, in which it allows a voluntary withdrawal of the connecting portion of the movable connector from the receptacle by a user, and - a locked position, wherein it prevents said removal of the connecting portion 20 of the mobile connector. Preferably, this connector locking mechanism is mounted entirely on the connector receptacle, for example a receptacle as explained above, so that the receptacle carries the locking mechanism with it when it is removed from the receptacle. wall.

Preferably, this connector locking mechanism is formed by a receptacle having a protective housing adapted to receive and protect a connection portion of the movable connector, which in particular carries the electrical connection contacts, for example to protect it from water runoff. water but also unwanted accesses, for example to prevent contact with the user and / or insects and dust. This locking mechanism then has a receptacle hook having a shape arranged to cooperate by mechanical stop with a shape of a hook carried by the movable connector. In addition, at least one of these hooks forms a movable hook: that is to say the receptacle hook or the connector hook, or both. This movable hook is arranged to be movable in a movement path between at least: 5 - a hooked position, wherein said hooks cooperate with each other to hold said movable connector in a storage position in which the connection portion is located at the inside of the protective housing, and - an unhooked position, wherein said movable hook is sufficiently spaced to allow extraction of the connection portion out of said protective housing. In the hooked position, for example waiting for use, the mobile connector is thus retained in its protective housing. The unhooked position allows the user to extract it from this housing to approach the vehicle to be loaded and connect it to its charging socket. In addition, this locking mechanism comprises a locking pin which can be moved between at least: - a locking position, in which the locking pin can be locked by an electric control so as to form a stop which prohibits movement hook moving from the hooked position to the unhooked position, and - a retracted position, wherein the locking finger allows said movement of the movable hook.

Thus, the intelligence of the terminal, or that of a remote controller, can automatically and / or remotely control a hook lock, which thus prevents the connector from being removed from its protective housing. According to yet another particularity of the invention, which can be implemented independently of the others, the terminal comprises a cooling system arranged to produce a flow of air so as to discharge to the outside air a thermal energy generated. inside the terminal, in particular by the charging circuit and the various other electrical and electronic components. According to this feature, this cooling system comprises at least one heat exchanger performing a heat transfer by sealed conduction between: - on the one hand, a so-called open part of the outer protection enclosure which encloses a volume forming a outside air circuit 5 from at least one external air inlet opening to at least one outside air outlet opening through at least a first so-called external exchange surface of said at least one exchanger thermal; and on the other hand, a so-called sealed part of the enclosure which encloses a sealed volume forming an internal air circuit in which at least one circulator circulates in closed circuit an interior air stream between at least one system to be cooled and at least a second exchange surface of said at least one heat exchanger. Preferably, the outside air circuit forms, between the inlet opening and the outlet opening, a continuous circuit without passing through an air filtration device, and for example without obstacle for any particle smaller than 1 mm. less than 0.1mm. Preferably, the outside air circuit further comprises at least one so-called external circulator, for example a fan. This is disposed within the outside air circuit so as to circulate air therefrom from the inlet opening to the outlet opening. Preferably, but not necessarily, it is disposed immediately upstream of said at least one heat exchanger so as to blow air from the circuit directly on exchange surfaces of said at least one heat exchanger, that is to say 25 oriented towards these exchange surfaces. It is for example disposed less than 10 cm and preferably less than 4 cm thereof. According to a particular embodiment, the volume enclosing the inner air circuit comprises: on the one hand, at least one chamber which bathes at least a first part of said at least one system to be cooled, and on the other hand a so-called downstream conduit connecting an upper portion of said chamber located above said first portion to cool with a bottom portion of said chamber below or including said first portion to be cooled. The terminal further comprises at least one duct circulator sealingly integrated with said downstream duct so as to impose a flow of air from said upper part to said lower part. According to another particular embodiment, the volume enclosing the inner air circuit comprises: on the one hand, at least a first chamber which bathes at least a first part of the system to be cooled, and, on the other hand, at least one second chamber which bathes the internal exchange surface of said at least one heat exchanger, and preferably also a second part of the system to be cooled, said second chamber being disposed above said first chamber. The indoor air circuit comprises a so-called downstream conduit connecting said second chamber with said first chamber. Said internal air circuit further comprises: on the one hand, at least one duct circulator arranged in said duct 20 descending so as to impose a flow of air down from the second chamber to the first chamber; and on the other hand, at least one chamber circulator integrated in a wall separating said first and second chambers so as to impose a flow of air from said first chamber towards said second chamber. More particularly, the chamber circulator is arranged to blow air from the first chamber directly onto exchange surfaces of said at least one heat exchanger.

Preferably, these two embodiments of the cooling system are combined in a configuration in which the second chamber is located above the first chamber. The interior air flow is then forced downward by a first circulator into a duct down from the top chamber to the bottom of the bottom chamber, and is forced upward from the top of the chamber. from bottom to bottom of the upper chamber by a second circulator located in a wall separating the two chambers.

In a preferred embodiment, the various features disclosed herein are all combined within a single terminal. However, alternative embodiments are possible in any combination of these features.

As understood, such an architecture thus provides a more modular, simpler design and repair and maintenance terminal. The combination of the various features of the invention here exposed, all together but also partially, thus brings different advantages, each of which makes it possible to better exploit the others.

For example, an important advantage of such a terminal is its accessibility, thanks to this distribution of components between the base and the opening part, but also with the possibility of removing and carrying away the head containing the intelligence and the fragile elements. without dismantling the rest of the terminal.

However, the interior of the perfectly sealed terminal, without complex complex cooling system or introduction of outside air, allows for example to better exploit the increase in the number of internal components authorized by this distributed architecture. Similarly, the locking system of the mobile connection socket, combined with the receptacle and cable storage guide provides a controlled and optimized security especially with respect to third parties, which combines particularly well with the strengthening of the possibilities of unprotected installation and difficult environment offered by the architecture and / or its cooling system.

According to the embodiments, and more particularly in the preferred embodiment, the invention thus brings advantages in the flexibility of design, use and maintenance; as well as a better seal, for example to moisture and dust; and decreases the heating problems especially in prolonged use, and under difficult climatic conditions. In particular, it reduces the problems of repair and maintenance, providing better accessibility inside the terminal despite increased complexity, especially to take into account these different other constraints.

Preferably, the various constituent members and essential elements of the terminal are arranged in its two fixed and movable parts in a distinct and precise manner: the elements serving for the air cooling and recirculation system are preferably on the door but also possibly distributed between the door and the base; the electrical and electronic power elements are preferably, or even exclusively, on the terminal, that is to say for example the power electronics carrying out the load and / or the pilot wire (s) and / or the components Powerline Communication System (PLC); - The intelligence of the terminal is preferably or exclusively on the head of the terminal, which is preferably removable as explained below; that is, the interactive and / or digital management components of the Human Machine Interface (HMI), such as a PC-type computer, a controller card, a display and / or an electronic or optical badge reader. Various embodiments of the invention are provided, integrating, according to all of their possible combinations, the various optional features set forth herein.

DESCRIPTION OF AN EXAMPLE EMBODIMENT FIG. 1 to FIGURE 5 illustrates an exemplary implementation of the preferred embodiment of the invention, here implemented by way of example as a charging station for vehicles. electric.

10 This is a self-service loading system intended to be installed in a public access road environment, for example to provide a network of charging points to electric vehicle owners in an agglomeration or region. This type of system is also usable, alternatively or at the same time, for a distributed network for renting self-service electric vehicles. This is for example a network comprising numerous parking and charging locations in which vehicles are self-service supported in any location and are self-service in a different location anywhere in the world. network.

The invention is of particular interest for these types of networks, inter alia because they comprise a large number of terminals or stations, installed directly on the public road and distributed in a distributed manner within a very wide area.

As illustrated in FIGURE 1 and FIGURE 2, this terminal 1 has in the closed position a vertical cylinder shape fixed to the ground 901, terminating upwards by an oblique cutaway forming a bevel, and which carries a display screen 42 and interactive input means, for example keys and / or a touch screen and / or badge or tag reading means. This is for example a tactile transflective screen, mounted under a transparent protection slab, for example glass or polycarbonate. In the vertical part of the tip of the bevel, the outer wall comprises a portion called "verrine", a translucent material and preferably colored. This portion forms a protection for the tip 3034615 - 16 - less offensive than the sheet, and which can be illuminated by a light on inside the terminal to provide a visible signal at a distance indicating one or more states of the terminal. In its lowest part, the terminal is surrounded by a plinth 5 integral with the outer wall, here divided into two half-baseboards, painted stainless steel sheet or in the form of an elastomeric coating. On its outer walls 21, 31, the terminal comprises electrical connection elements for connection with the battery to be recharged.

In the present case, by way of example, the terminal carries on the one hand a fixed wall-type electrical socket 34, for example a socket usable for connecting a standard charging cable provided by the user. The terminal also carries a base or receptacle 33 removably receiving a connection handle or connector 32.

As illustrated in FIGURE 3 and FIGURE 4, this branching handle 32 is electrically connected to a power electronics 61 by an electric cable 328 unwound from an automatic winder 329. This power electronics is here powered by a connection to underground cables. (not shown), and controlled by a control electronics. This is for example a local electronic 62 and / or a digital connection with a remote control center by a remote communication interface, for example by line carrier and / or a digital network such as the Internet. As illustrated more particularly in FIGURE 4, the terminal 25 comprises a mobile part 31 forming a sealable door 3, here by crushing joints 211, 311, on a fixed portion 21 forming a base statically implanted in the ground 901 As an example that can be subject to many variations, the door 3 is here articulated on the base 2 by pivoting about hinges 213 vertical 30 (FIGURE 1 and FIGURE 4), which allows a better stability in the position of opening. As seen in FIGURE 4, the outer wall 31 of the door 3 represents a major part of the periphery of the terminal, for example about two-thirds. In its central part, the door discovers the components 61 of the charging circuit. The components thus discovered are located mainly on the base. In the present example, the upper part of the door supports 5 different components, in particular the cooling system such as fans, the inlet of the cooling down duct, and a wall separating the top and the bottom of the terminal. The components of the top of the door are located on a portion of the inner surface 302 directed upwards, which makes them particularly accessible.

In the central part of the door, its inner surface 302 has very little component. At this height, the components 61 discovered by the door are mostly even fully implanted on the inner surface 203 of the base. Because the door is two-thirds of the periphery, it discovers the components of the terminal on most of their outer surfaces. They are thus very accessible too. The door is locked in the closed position by a two-part mechanism. A lock 39 ensures the mechanical maintenance of the door, and is operable by a simple but robust form of maneuver, for example a square or a triangle. An impermeable lock 38, vandal-proof and a single-key type, is arranged to conceal and seal the access opening to the operating form of the lock lock 39.

As seen in FIG. 3, an outside air circuit 7 is made entirely in the base 2. This outside air circuit is of the open type and is supplied with outside air by an air inlet 701, here protected. by a simple grid, preferably arranged in the upper part, or higher, of the terminal 1. As illustrated by the hatched arrows, the outside air is sucked from the outside by two fans 71 (FIGURE 5) which blow it directly. on the outer exchange surfaces 727 of a heat exchanger 72 fixed in a wall of the base. Once it has absorbed thermal energy in contact with the exchanger 72, the outside air is discharged 3034615 - 18 - to an outside air outlet 702, here protected by a simple gate, preferably located in lower part, or lower, of the terminal 1. Thus, we see that the outer exchange surfaces 728 of the heat exchanger 72 are protected from contact with the passers or the user 5 of the terminal, and therefore do not risk to burn them. As illustrated in FIG. 3, an interior air circuit 8 is made in a sealed volume 800, here shown in thick dashed lines. This interior volume forms an inner chamber 80, which is enclosed, once the door is closed on the base, between an inner surface 203 of the base and an inner surface 302 of the door. This inner chamber 80 delimits a volume enclosing the inner air circuit 8 and comprises: on the one hand, at least one chamber 801 which bathes at least a first part 61 of the cooling system implanted on the inner surface 15 of the base and including the load circuit and / or power electronics; and on the other hand, a downcomer 82 implanted in the door 3 or on its inner surface 302 and connecting an upper part of said chamber 801 located above said first portion 61 to be cooled with a lower portion of said chamber 801 below or including said first portion to be cooled. This inner chamber 80 further comprises a duct circulator 81 sealingly integrated with said down duct 82 (at the inlet or the outlet or between the two) so as to impose an air circulation 25 from said upper part up to to said lower part, as represented by the white arrows. In this embodiment, the volume enclosing the inner air circuit 8 further comprises: on the one hand, at least a first chamber 801 which bathes at least a first portion 61 of the cooling system implanted on the inner surface 203 base 2 and including the charging circuit and / or power electronics; and secondly, at least a second chamber 802 which bathes at least a second portion 62 of the system to be cooled including at least one digital data processing circuit arranged to perform a management of the operation of the terminal and / or an external display user interface 42, and / or badge or tag reading means. This volume further comprises at least one chamber circulator 83 integrated in a wall 84 separating said first and second chambers so as to impose a flow of air from said first chamber 801 to said second chamber 802. As illustrated in FIG. the embodiment presented here combines the first and second particular embodiments of the cooling system. Thus, the descending duct 82 circulates the air from the second chamber 802, forming the upper part of the overall chamber 80, to the first chamber 801 which forms the lower part. This first chamber 801 includes the first part to be cooled 61, and it itself receives the descending duct 82 in its own lower part, 15 which favors the sweeping of the lower part 61 of the circuits to be cooled. The charging circuit and / or power electronics performing the charging function is located on the inner surface of the base, within the inner chamber 80, and more particularly within the first chamber 801 located in the lower part. This circuit is underlined in FIGURE 3 surrounded by an oval in fine dotted line. The upper face of the terminal, which includes the screen 42, on its inner face 488 all or part of the digital management components of the terminal and the user interface.

FIG. 6 illustrates this inner face 488 of the upper part 4 of the terminal 1, once completely detached. In this embodiment, the upper face of the protective enclosure of the terminal, and here of the sealed enclosure of the inner circuit 8, is carried by an upper part 4 movable relative to the base, and which can be closed again. on this base sealingly by a peripheral seal 214. In this embodiment, the assembly of the upper end 4 can thus be extracted by an upward translation after unlocking from the inside four fasteners per latch fixed on the inner walls of the base, which cooperated with four locking hooks 412 protruding from the inner surface 488 of the upper part 4, to hold the latter in the closed position and pressed against the seal 214 which separates it vertical walls 21 of the base. The upper part 4 or head of the terminal 1 is thus completely and easily removable. It contains the most fragile and complex electronic parts. It is thus possible to easily replace all the upper part 4 without complex operations on the site, for example to realize in the workshop work on its electronics 62, for example complex operations such as repair or update, more comfortable more efficient and in a more controlled environment. As illustrated in FIG. 5, the main radiator or radiators 621 of the digital circuit, for example the microprocessor which manages the terminal, are preferably arranged directly opposite the internal exchange surfaces 728 of the heat exchanger 72, in a parallel manner and at least 15 of 3cm. As can be understood, the terminal 1 thus has an inner compartment 80 completely sealed against moisture and dust inside the terminal, in particular at the level of the "essential" elements 20 constituting the terminal. The system thus comprises two separate circuits. On the one hand, it comprises an air duct in contact with the outside, arranged here in the fixed part of the terminal, that is to say acting as a base for the terminal. This results in a loop outside the terminal, which is or can be driven non-continuously, only according to the needs and the temperature of the heat exchanger. This is the only communication with the inside of the terminal, without air exchange and with which the outside has no direct access. On the other hand, it comprises an enclosed space with closed circuit air mixing, so as not to have moisture and dust in the inner zone of the terminal, where all the sensitive electrical and electronic components are positioned. This gives a loop inside the terminal. This is preferably continuously controlled by maintaining a permanent air flow inside the terminal. Such an arrangement makes it possible in particular to optimize the air inlet zone in the rear upper part of the terminal, to limit access to the hot surfaces from the outside, and to optimize the recirculation of air in the sealed internal zone, which optimizes the technical cooling solution in terms of performance and cost. FIGURE 7, FIGURE 8 and FIGURE 9 illustrate the door locking mechanism of the terminal, provided by two locks 38, 39 actuated successively.

This double arrangement provides complementary cooperation between a security key and an operating key, here provided with a male square shape. These two locks are here mounted on the outer wall 31 of the door 3, but could also be mounted on the wall 21 of the base 2.

The operating key is introduced into a maneuvering orifice 390 passing through the outer wall 31. It is engaged with a maneuvering form 391, here a female square within an opening locking mechanism. In the present example, this mechanism is achieved by a cremone 392, whose actuation by the operating key 20 rotates two shafts 393 each carrying a bolt 394 at its end. As understood, such a form of maneuvering makes it possible to maneuver a robust and powerful locking mechanism capable of transmitting a high maneuvering torque around its axis A39, and controlling one or more robust anchoring points and possibly including one or more pressure ramps. It thus allows a solid and well-applied retention of the wall 31 of the door 3 against the seals 211 and 311 ensuring its sealing with the wall 21 of the base 2. The security key of an authorized person is introduced into a lock of prohibition 38, for example a security lock of a known type, here provided with a security barrel 381 with a central pin 380 hosting a single profile on its periphery. By actuating this prohibition lock 38 about its axis A38, the security key pivots a lever 382 which carries at its end a concealment member 383, here a flat disc carrying on its outer face a seal. 3034615 - 22 - The operation of this prohibition lock thus requires a low torque, which allows to use a lock 38 of small size and inexpensive. As illustrated in FIGURE 7 and FIGURE 8, when the lock 5 prohibition 38 is in the closed position, its occulting member 383 prevents access to the operating form 391 of the operating lock 39, both for water only for a tool used by an unauthorized person. By introducing the security key in the lock lock 38 and 10 by actuating it in translation D38 then in rotation R38 (or simultaneously according to other embodiments), an authorized person can discover the operating port 391. It can then introduce its operating key, and rotate it R39 to rotate R394 the bolts 394 and thus allow the opening of the door 3.

The operations are done in reverse order for closing: locking the door 3 by the operating key, then concealment of the operating port 391 by rotation of the security key, and plating the seal of the body of the occultation 383 against the maneuvering port by a translation under the effect of a spring during removal of the security key.

FIG. 10, FIG. 11 and FIG. 12 illustrate the configuration of the receptacle receiving the mobile connector on the outer wall of the terminal, here borne by the outer wall 31 of the mobile door 3. In this example, in addition to the fixed socket 34, the terminal comprises an electric charging cable 328 permanently connected inside the terminal to the charging circuit 61 and stored around an automatic reel 329 implanted inside the terminal and only on the inner surface 302 of the movable door 3. Preferably, this retractor is accessible and / or removable from the inside of the door. The charging circuit and possibly the winder are controlled by the terminal electronics. As shown in FIGURE 1 and FIGURE 12, this electric charging cable 328 carries at its free end a movable connector 32 provided with a handling handle 320. Apart from use, this connector 3034615 - 23 - is intended to be stored in a receptacle 33 which passes through the outer wall of the terminal, here that 31 of the door 3. This receptacle 33 is made in a single piece, for example by injection molded plastic.

In the lower part, it comprises a guide orifice 333 through which said cable 328 leaves the terminal, and which guides it during its extraction but also during its rewinding by the winder 329. This guide orifice is here reinforced in its lower part, which undergoes the most friction from the cable 328, by a reinforcing plate 335 of complementary shape, for example a stamped metal strip with a thickness of the order of 5 tenths of a millimeter glued to the receptacle 33 plastic. The guide port 333 has a constriction 334 sized to retain a stop ball 3281 secured around the charging cable 328, thereby providing an end stop during automatic or controlled rewinding. In the center, this receptacle comprises a housing 330 which receives the handle 320 and the hand of the user who holds it, to enable it to conveniently unhook and hang the connector. In the upper part, it has a protective housing 331 having a shape complementary to the outer profile of the movable connector, so as to be able to surround its connection portion 327 when it is in a waiting position. This connecting portion 327, which carries the electrical connection contacts, is thus protected from any contact with the user, as well as water and possibly insects. This is for example a standardized plug for charging electric vehicles, for example a type "Ti" plug. As illustrated in FIGURE 12 to FIGURE 14, the movable connector comprises at its end a connector hook 322 which protrudes into the insertion direction D32 'of its connecting portion 327. In the standby position, this hook abuts against a shoulder making a receptacle hook 332 and positioned to retain the connector 32 in its housing 331 and 330. In this embodiment, this connector hook 322 extends inside its handle and is there articulated, here around a rotation shaft 3220, so as to be able to deviate from the receptacle hook 332. This movement D322 is for example obtained by a pressure of the user 5 on a button or trigger 321 which protrudes from the handle 320. Under the effect of such a pressure, the trigger pivots around a shaft 3210 to come to press a rear portion 3221 of the connector hook 322 and thus remove it D322 from the receptacle hook 332, allowing nsi to the connecting portion 327 of the connector 32 to be extracted from its housing 331, for example according to a translation D32. It should be noted that other embodiments are possible, in which the receptacle hook is movable while the connector hook is fixed relative to the connector, or in which the two hooks are movable.

More specifically, as illustrated in FIG. 13 through FIGURE 15, the locking mechanism comprises a locking device 35 comprising a movable locking pin 351 which can be moved D35, to prevent or allow the spacing D322 of the connector hook 322. This locking pin 351 here constitutes an end bent at the end of an arm, which is rotatable relative to the receptacle 33 around a shaft 350. The position of this locking pin 351 is detected by the electronic terminal of the terminal by means of a finger sensor 357, fixed for example to the receptacle 33. This finger sensor 357, for example an optical sensor 25 within a fork, detects the presence or absence of an end 358 arm bearing the locking finger. For example, this is a rear end located on the other side of its rotation shaft 350. When the connector hook 322 is engaged with the one 332 of the receptacle, the locking pin 351 is brought back and held in a so-called locking position, under the effect of an elastic means, here a return spring 359, as shown in FIGURE 13. In this locking position, the arm carrying the locking pin 351 can be locked by bearing a bearing 352 against the surface 361 of a locking rod 360 which is perpendicular thereto, here a bearing 352 located on the other side of the rotation shaft 350, as illustrated in FIGURE 13 FIGURE 15. This locking rod 360 is movable in longitudinal translation D36, in one direction and in the other, under the effect of an electromechanical actuator controlled by the electronics of the terminal or remotely, here a solenoid 369. This locking pin 360 bears a notch transverse heel 362 or a transverse flat, on the side of the bearing 352 of the locking arm.

When the solenoid is in the locking position, it is a cylindrical portion 361 of the rod 360 which is opposite the bearing surface 352, and thus prevents it from moving towards the axis A36 of this rod 360. 351 locking device can not deviate from the connector hook 322, which prevents the stall D322 and thus the extraction D32 of the mobile connector 32. The position of this locking rod 360 is detected by the electronics of the terminal by means of a locking sensor 367 fixed to the receptacle 33. This locking sensor 367, for example an optical sensor within a fork, detects the presence or absence of a tab 368 which protrudes laterally from this rod , and thus detects whether the locking rod 360 is or not in the unlocking position (or locking according to the location where the tab 368 is fixed). In the present example, the tab 368 is fixed so that its detection by the locking sensor 367 ensures that the rod 360 is in the unlocking position. In the locking position, as shown in FIGURE 15, this tab 368 is located outside of the sensor fork 367. When the solenoid 369 is in the unlocked position, as shown in FIGURE 14, this is the notch 362 which is in front of the range 352. This can therefore move towards the axis A36 of the rod 360, and thus allow a rotation of the arm which goes with a displacement D35 of the locking pin 351. 3034615 In this locking position but without locking, an inner face of the locking pin 351 is located just behind the connector hook 322, or even against its rear face. The presence of this finger 351 and the resistance that it exerts, under the effect of the spring, thus limits the risks that the hook 322 deviates from itself and that the connector is unhooked without action of the user, for example under the effect of vibration or a slight shock. On the other hand, if the user voluntarily presses the trigger 321 of the connector, the connector hook 322 tends to move away from D322 and presses on the inside face of the locking pin 351. The shape of this face and / or its orientation are determined, here in a slight rounding, so that the support of the hook 322 caused by the user allows him to move D35 blocking finger 351, and then continue his own displacement D322 to its unhooked position as illustrated in FIGURE 14. Once the hook 322 is completely retracted, the user can then extract D32 the connector of its housing 331 in the terminal. Thus, it is seen that it is the user who provides the stalling forces, through the displacement of the connector hook 322 and the locking pin 351. As required, the electronics of the terminal can, however, lock the mechanism. to prevent this stall D32 and lock the connector, with great resistance and without having to provide a force opposing those of the user. It is therefore possible to use a 369 actuator simple, compact, reliable, and low power.

When the mobile connector 32 is absent from its housing 331, its hook 322 is not there to hold the locking pin 351. This is then driven by the return spring 359 beyond the blocking position, downward in the figures, and its arm end 358 exits the finger sensor 357, upwardly in the figures.

The finger sensor 357 makes it possible to know the position of the locking finger 351: if the end 358 is detected, this means that the finger 351 is in the locked position, and therefore the connector is in place in its 3034615. 27 - housing and that it is correctly hooked, as in FIGURE 12 and FIGURE 13; if this end 358 is not detected, it means that the connector is badly hooked, as in FIG. 14, or that it is absent; and therefore to know if the movable connector 32, and in particular its connecting portion 327, is or not present in its housing 331. The locking sensor 367 makes it possible to check whether the rod 360 is or is not in a given position, here the unlock position. Thus, the sensors 357 and 367 allow the system to know at any time the state of the locking device 35 and the locking device 36, which ensures the consistency of the behavior of the controller and facilitates the diagnosis of malfunctions including remote. Of course, the invention is not limited to the examples which have just been described and numerous adjustments can be made to these examples without departing from the scope of the invention.
