Definitions
- the present description generally relates to electrical connection systems and, more particularly, to a cable connection system.
- the present description applies more particularly to a cable connection system of a motor vehicle battery or the like to recharge.
- the connection for charging a battery or a set of batteries for a motor vehicle to an electricity distribution system generally comprises a cable connected to a part to an electronic circuit managing the charge of the battery on the vehicle side and on the other hand to a power supply installation. Most often, the cable is located at the charging station. Most often, a cable having a plug at each end is connected, on the one hand, to the installation and, on the other hand, to the vehicle. Sometimes the cable is permanently connected to the vehicle. With the development of electric vehicles, we see appear solutions in which the cable is stored in the trunk of the motor vehicle. The user plugs both ends of the cable, respectively to the vehicle and to the charging station.
- connection cable often tends to drag on the ground, which is particularly inconvenient and messy for the user.

- control signals exchanged with it Such a solution, however, is incompatible with the use of charging plugs in domestic installations that are not specifically provided for such a refill.
- an embodiment aims to electrically secure a connection to a recharging installation and, in particular, to ensure that the connection includes a connection to the ground.
- an embodiment aims at securing the use of domestic plugs for recharging a battery for electric vehicles.
- an embodiment provides an electric cable winding device having a cylindrical hub, perforated surface and open at at least one of its ends, the cable having at least one conductor and an outer surface sheath of non-regular section.
- projecting portions of the outer surface of the sheath define air circulation spaces between turns of the cable when the latter is wound.
- the air circulation spaces are, over the entire length of the coiled cable, axial and radial.

- FIG. 11 very schematically shows an embodiment of an electrical connection system using a plug of the type of that of FIG. 10.
- Figure 1 shows, very schematically, an example of a charging system of a battery of a motor vehicle and such a vehicle.
- An electric or hybrid vehicle V comprises one or more batteries 1 (BAT) intended to provide it with the energy necessary for its propulsion. These batteries are connected to one or more load management and control devices (chargers) 2 for controlling their charge when they are connected to an electricity supply installation 3.
- BAT batteries 1
- chargers load management and control devices
- the installation 3 can be a public charging station of the service station type, a domestic installation (for example, at the vehicle user's home), etc.
- batteries include generally a set of several batteries and all that will be described later applies regardless of the number of batteries that make up the “battery” of the vehicle, these batteries are usually recharged through a common device.
- the battery In a so-called "fast charge” mode, the battery is charged under a current of several tens of amperes (for example, of the order of 150A).
- the load is carried out from specific installations equipped with a suitable section cable and safety devices. The free end of the cable is then connected to a socket of the vehicle.
- the battery is charged under a current of a few tens of amperes at most, typically under a current compatible with the use of plugs of a domestic installation. For example, in France, this amounts to being able to charge the battery from a socket called 16A.
- the connection cable of the battery for charging is no longer necessarily at the charging station, but more and more often at the vehicle side. This causes, among other things, constraints in terms of congestion.
- electric vehicles are usually provided with a cable "bulk", intended to be connected on the one hand to the vehicle and on the other hand to a power supply outlet.
- a slow charge can last more than ten hours. It is necessary to facilitate the handling of the user while ensuring its comfort and safety.
- the charger 2 is connected using a cable 4 provided at its end on the installation side 3 with a plug 5 intended to be engaged in a socket 7 of the installation.
- the end of the cable 4 is either permanently connected to the charger (as shown) or is also connected via a plug.
- FIG. 2 schematically represents an embodiment of an equipment inside the vehicle V.
- a cable reel 6 to reduce the size of the latter.
- One (fixed) end of the cable 4 is connected to the charger 2 (CTRL).
- CTRL charger 2
- the other end, which can be rolled out of the cable, is connected to plug 5.
- Ventilated cable reels have already been proposed in an attempt to overcome this phenomenon in other domestic applications.
- the solutions adopted in these applications can not be transposed to an application for recharging electric vehicle batteries, particularly because of the particular constraints of this application.
- the equipment for example a garden tool
- the user moves this equipment. Therefore, the complete unwinding of the cable is often necessary for reasons other than heating.
- the cable is regularly moved and therefore does not remain in a pile. This is not the case of charging a vehicle that is stationary during charging, the length of the cable and its position therefore remain fixed throughout the recharge.
- the solutions used for vacuum cleaners which consist of using a powerful fan, or the suction power of the vacuum cleaner itself (which is a depression of the order of 0.3 bar (3.10 ⁇ Pa )), at the level of the winder are not appropriate.
- the fan when the fan is used in a vacuum cleaner (or a reel used to power a power tool), the engine of the vacuum cleaner or the tool is already making noise and the noise added by the fan is negligible.
- this fan does not remain in operation when the vacuum cleaner or tool is not used.
- a vehicle battery is recharged while the vehicle is not in use. The fact that the charger must remain plugged in the absence of the user and in domestic locations generates a strong constraint in terms of noise.
- an electrical cable of particular structure is provided.
- the internal structure of the cable comprises as many conductors as necessary, isolated from each other inside a sheath, in the manner of a conventional cable.
- the outer surface of the sheath has a non-regular section.
- the outer surface has projecting portions of a bottom or base.
- the function of these projections, or irregularities, is to define air circulation spaces through the cable reel when the cable is wound on itself, or through sections of this cable superimposed (for example if the cable is laid in piles).
- Figure 3 is a partial perspective view of an embodiment of a cable 4a according to the first aspect.
- the cable 4a comprises three conductors 41 (for example of phase), 42 (for example of neutral) and 43 (for example of earth), individually isolated from each other, and then embedded in an insulating sheath 45a.
- the sheath 45a comprises, in outer surface, preferably at regular intervals, gadroons or rings 452 creating irregularities in this outer surface. Between the rings, the outer surface of the sheath has an inner diameter (or diameter of the base of the sheath). The outer diameter of the rings (or height of the surface irregularities) defines, with respect to the internal diameter, intervals or spaces of air circulation.
- the interval between the rings 452 and their external diameter, which determines the size of the air circulation spaces, depend on the application and, in particular, on the amount of heat to be discharged, which depends, among other things, on the section of the conductors. and the amperage to which they must be subjected.
- Figure 4 is a partial perspective view in section of the cable 4a of Figure 3 wound.
- Figure 5 is another partial perspective view of the cable 4a of Figure 3 wound.
- Figure 6 is a partial perspective view of another embodiment of a cable 4b according to the first aspect.
- the sheath 45b has a projecting portion 454 of its outer face defining a part with non-contiguous turns, wound coaxially around the cable.
- the base of the sheath 45b also has the form of a winding, coaxial with the cable axis, non-contiguous turns.
- the difference in diameter between the inner and outer diameters of the surface of the sheath 45b, and the non-contiguous turn pattern create air flow channels when the cable is wound. on itself, in the axial and radial directions of the winding.
- the interval between the turns 454 and their outer diameter, which determines the size of the air circulation spaces, also depend on the application and in particular the amount of heat to be evacuated.
- FIG. 6 illustrates a variation in the composition of the cable which here comprises four conductors 41, 42, 43 and 44. It may be a cable equipped with a control wire or pilot wire or a cable having two earth conductors 43 and 44, isolated from each other, as will be seen in connection with the third aspect which will be described later.
- the number of drivers can vary.
- the cable may include multiple pilot wires.
- five conductors three phases, one neutral, one earth
- six conductors three phases, one neutral, two earths
- the assembly of the sheath 45 is made in one piece, for example by spinning plastics material.
- the difference in thickness between the outer diameter, rings 452 or portion 454, and the diameter of the base of the cable 4a or 4b is greater than about 3 millimeters.
- the interval between rings 452 or between turns of the portion 454 in the axial direction is greater than about 3 mm, preferably greater than about 1 cm. Such minimal dimensions promote the circulation of air by simple natural convection.
- the internal diameter of the base sheath 45 ( 45a or 45b) is about 1 cm and the outer diameter of the rings 452 or the portion 454 is about 1.4 cm.
- such a cable structure allows, for the same heating, the passage of a current of an intensity greater than that of a conventional cable when the cable is wound.
- a cable 4 (4a or 4b) thus produced may, in a simplified embodiment, be used with a standard winder, the natural convection through the turns being sufficient to cool it.
- Figure 7 is a schematic representation of an embodiment of a cable reel 6, equipped with an embodiment of a cable 4 according to the first aspect.
- the winding device 6 comprises a cylindrical hub 62, openwork surface (openings 622) and open (opening 624) at at least one of its ends.
- the role of the openings 622 and 624 is to improve the flow of air through the cable 4. The greater the number of openings, the better. We will therefore compromise with the desired mechanical strength for the hub 62.
- the openings 622 have a diameter, or are within a diameter, greater than 3 millimeters. The inventors have indeed found that from a diameter of 3 mm, the air flow was improved.
- the winder 6 further comprises a fan 64 blowing air inside the hub in a direction approximately coaxial with the hub (from the open end 624).
- the hub is then open at one of its ends to force the pulsed air to pass through the openings 622, then to circulate through the cable 4 wound.
- the air flow channels formed in the cable 4 participate in a power reduction of the fan.
- the power of the fan should allow to force the circulation between contiguous coils of the coiled cable, which is in practice almost impossible and incompatible with low noise.
- the resistance to the passage of air is low and the fan can be low power, so silent and less expensive.
- ventilation can be provided by a fan providing an overpressure of a few mbar (10 2 Pa).
- the reel 6 comprises a hub rotation drive member 66.
- This is, for example, a spring device, arming automatically as the user unwinds the cable 4.
- using a rewinding motor of the cable moved by the energy provided by the battery.
- the reel 6 and its various components are housed in a housing 68 ( Figure 2), partially shown in Figure 7.
- the housing prevents elements that block the operation of the reel.
- the housing 68 comprises, in the lower part, one or more openings 682 serving to evacuate any impurities. accumulated around the cable and falling by gravity, or water if the cable 4 is wet when rewinding.
- Figure 7 is schematic and functional, the practical embodiment of such a reel being within the reach of the skilled person from the functional indications given above.

- FIG. 9 is a partial perspective view of an embodiment of a female connector 53 of a plug 5b of the device of FIG. 8.
- the cable 4 (for example, of the cable type 4b, FIG. 6) comprises two conductors 43 and 44 intended to be connected to the ground. These two conductors are individually connected to two distinct portions 533 and 534 of a connector 53 of the plug 5b.
- the two parts 533 and 534 are not in electrical contact with each other as long as the plug is not engaged in a socket 7.
- the parts 533 and 534 each constitute a sector of a female connector of cylindrical general shape ( Figure 9) for receiving a male connector 73 of a socket 7.
- the plug 5b has a connector of less than the number of conductors of the cable 4b.
- the receptacle 7 comprises two female connectors 71 and 72 intended for the connectors (males) 51 and 52 of the plug 5b, and a male connector 73.
- the connectors 71 to 73 are connected to wires ( designated overall by a cable 76) of the electricity supply installation.
- the earth connector 73 (dashed side plug 5b in Figure 8) electrically contacts the two parts 533 and 534 and thus connects the conductors 43 and 44.
- the conductors 41 and 42 are connected to the charger itself, for example via a rectifier 23.
- Two conductors 21 and 22 of the charger are connected to the terminals (positive (-) and negative (+)) of the battery 1.
- One of the conductors 43 and 44 (for example the conductor 43) is connected directly to the mass M (metal frame) of the vehicle.
- the other earth conductor 44 is also connected to the ground M, but via an electronic circuit 92 for checking electrical continuity between the conductors 43 and 44.
- Battery side typically acting as a battery of traction, it is usually isolated.
- the circuit 92 generates an alternating signal, preferably at a frequency different from that of the alternating voltage supplied by the electrical network, that it emits on the conductor 44 via a transformer 93.
- the circuit 92 detects the impedance of the circuit by measuring the current and the voltage supplied.
- continuity detection circuit embodiments may be provided to detect the grounding of at least one of the leads 43 or 44.
- Another benefit is that all detection
- the detection electronics is charger side. Thus, no intervention is necessary on the side of the electricity supply installation.
- FIG. 8 The representation of Figure 8 is schematic and functional.
- the practical achievements of a continuity detection circuit charger side 2, and a connector, female or male, adapted to establish the continuity between the two conductors 43 and 44 when there is a connector, male or female, grounding 83 a socket 7 are within the reach of the skilled person from the functional indications given above.
- Fig. 10 shows an embodiment of a temperature sensing device associated with a plug 5a according to the third aspect.
- FIG. 11 very schematically shows an embodiment of an electrical connection system using a plug 5a of the type of FIG. 10.
- plug 5a has three connectors
- the ends of the conductors 41, 42 and 43 of a cable 4 are connected (for example, welded, crimped or screwed) to the respective connectors 51 to 53.
- the assembly is enclosed in an insulating housing 58.
- Such a plug is intended for a socket 7 ( Figure 11) whose ground connector 73 (male) is protruding from the apparent face of the socket so that the earth is the first connected conductor.
- the socket 7 is connected, by a cable 76, to a source of electricity supply (not shown), for example the distribution table of a domestic installation.
- the cable 4 connected, at its other end, to the battery charger 2 of a vehicle is represented by means of a winder 6.
- Plug 5a has at least one temperature sensor.
- each connector 51, 52 conveying current in normal operation (phase and neutral) is equipped with a temperature sensor 81, respectively 82.
- a temperature sensor 81 In an embodiment where a single sensor is provided, it is placed closer to the connectors, for example, halfway between the two connectors 51 and 52.
- a simple realization of temperature sensors is to use negative temperature coefficient resistors (CTN).
- the sensors 81 and 82 are connected to an electronic circuit 85 for interpreting the temperature and, for example, for comparing this temperature with a threshold.
- the circuit 85 is integrated in the plug 5a and communicates with the battery charger (2, Figure 11).
- the charger 2 takes into account the temperature detected to allow or interrupt the charging of the battery, or even to control the charging current taken from the installation so that the temperature of the socket 7 remains acceptable and safe.
- the communication between the circuit 85 and the charger 2 can be carried out via one or more additional conductors 86 (pilot wires) provided in the cable 4.
- this communication is effected by means of carrier current using the conductors 41 and 42 (the plug then comprising a transmitter / receiver per current carrier connected to the conductors 41 and 42 of the cable 4), which avoids a galvanic isolation of the circuit 85.
- the circuit 85 controls at least one switch (not shown) integrated in the plug 5a and interposed on the conductor 41 or the conductor 42, which opens the electrical circuit if the temperature exceeds a predetermined threshold.
- An advantage of the embodiments that have been described is that they make it possible to secure and make practical and comfortable the charging of a battery of an electric vehicle, including from a non-dedicated installation, for example a domestic installation.
