Description

Title of the invention: Electric vehicle charging device comprising a connection pin

[0001] The present invention relates to an electric vehicle charging device, of the type comprising a current source and a current supply device for a battery of the electric vehicle, said supply device comprising at least one arm having at one of its ends a connection device, electrically connected to the current source, and intended to be electrically connected to a complementary connection device of the electric vehicle electrically connected to the battery of the electric vehicle, said arm being movable between a retracted position, in which the connection device extends into a storage volume of the charging device, and a deployed position, in which the connection device extends outside said storage volume, opposite the complementary connection device of the electric vehicle.

[0002] The invention also relates to an assembly comprising such a charging device and an electric vehicle.

[0003] It is known to provide electric vehicle charging stations where an electric vehicle is received and a vehicle occupant or operator connects a power cable to a corresponding socket on the vehicle. Such charging stations have the disadvantage that they require user intervention to connect the electric vehicle to a power source.

[0004] To overcome this drawback, a charging station has been proposed, in which an arm carrying an electrical connector is arranged to move autonomously to a complementary connection device of the vehicle to plug the electrical connector into a socket of the complementary connection device when the electric vehicle is received at the charging station.

[0005] To ensure that the electrical connector can be plugged into the socket of the auxiliary connection device without user intervention, the arm must be precisely positioned relative to the auxiliary connection device. If the arm is not aligned with the auxiliary connection device, the electrical connector cannot be inserted into the socket of the auxiliary connection device. To ensure this precise positioning, the electric vehicle must be positioned exactly where the arm is aligned with the auxiliary connection device, or the arm's position must be adjustable to accommodate the position of the auxiliary connection device when the vehicle Electricity is received at the charging station. Regardless of the solution chosen, the charging station has a complex architecture and is not simple to implement.

[0006] One of the aims of the invention is to overcome these drawbacks by providing a charging device for an electric vehicle that can supply current to the vehicle's battery in a simple way, without user intervention and ensuring rapid battery charging.

[0007] To this end, the invention relates to a charging device of the aforementioned type, in which the connection device includes at least one connection pin arranged to supply current to the complementary connection device by pressing against said complementary connection device, said connection pin being intended to be applied against said complementary connection device in the deployed position of the arm.

[0008] By using a connection pin arranged to supply power to the auxiliary connection device by pressing against the auxiliary connection device, the charging device can operate autonomously and without requiring precise positioning of the vehicle relative to the arm of the power supply device. Indeed, the electrical connection of the auxiliary connection device to the power source does not require the insertion of a male connector into a female connector, since it is sufficient to position the connection pin against the power supply device to ensure this connection.Thus, by choosing appropriate dimensions for the connection pin, the supplementary connection device can be positioned approximately opposite the power supply device's connection device, as long as this positioning allows the connection pin to make contact with the supplementary connection device. Furthermore, the charging device is compatible with a very high current intensity, ensuring rapid battery charging.

[0009] The charging device according to the invention may further comprise one or more of the following features, taken individually or in any technically feasible combination: - the connection device includes at least one positive pin, electrically connected to a positive terminal of the current source, and at least one negative pin, electrically connected to a negative terminal of the current source, the positive pin being intended to be applied against a positive pad of the complementary connection device and the negative pin being intended to be applied against a negative pad of the complementary connection device in the deployed position of the arm; - The charging device includes a temperature regulation device electric vehicle battery temperature, said control device comprising a control fluid source and at least one control fluid inlet line in fluidic communication with the fluid source, said inlet line comprising a connection fitting to an inlet of an electric vehicle battery temperature control circuit, said inlet line being movable between a retracted position, in which said inlet line and the connection fitting (50) extend into the storage volume of the charging device, and a deployed position, in which at least the connection fitting extends outside said storage volume and is connectable to the inlet of the electric vehicle control circuit; the control device further includes a control fluid outlet line, said outlet line including a connection fitting to an outlet of the electric vehicle control circuit, said outlet line being movable between a retracted position, in which said outlet line and the connection fitting extend into the storage volume of the charging device, and a deployed position, in which at least the connection fitting extends outside said storage volume and is connectable to the outlet of the electric vehicle control circuit; the storage volume extends under a floor of the charging device, the electric vehicle being intended to be placed on said floor, so as to place the additional connection device of the electric vehicle opposite the storage volume, the connection device extending in projection above the floor in the deployed position; the floor includes a receiving device for at least one wheel of the electric vehicle, the storage volume being positioned relative to said receiving device so that the additional connection device of the electric vehicle extends in relation to the storage volume when the wheel is received in the receiving device; the receiving device is connected to the arm by a connecting device arranged to move the arm from the retracted position to the deployed position when a wheel (68) of an electric vehicle is received in the receiving device; the storage volume is closed by at least one movable flap between a closed position, in which the flap closes the storage volume when the arm is in the retracted position, and an open position, in which the flap releases access to the storage volume when the arm is in the deployed position.

[0010] According to another aspect, the invention also relates to an assembly comprising a charging device as described above and an electric vehicle, comprising a complementary connection device, said complementary connection device being placed opposite the storage volume of the charging device, the connection pin being applied against said complementary connection device in the deployed position of the arm of the power device.

[0011] According to an optional feature of the assembly, the connection fitting of the inlet pipe of the control device is in fluidic communication with an inlet of a temperature control circuit of the electric vehicle battery in the deployed position of the inlet pipe, said temperature control circuit being a separate control circuit from another isolated control circuit inside the electric vehicle.

[0012] Other aspects and advantages of the invention will become more apparent upon reading the following description, given solely by way of non-limiting example, and made with reference to the accompanying drawings in which:

[0016] [Fig.4] - [Fig.4] is a schematic cross-sectional representation of a part of the charging device according to an embodiment of the invention, and

[0017] [Fig. 5] [Fig. 6] - Figs. 5 and 6 are schematic cross-sectional representations of the charging device of the [Fig.1] in different positions of the charging device.

[0018] With reference to [Fig. 1], a charging device 1 for an electric vehicle 2 is described, which supplies electricity to an electric vehicle battery 4 in order to recharge it. The charging device 1 is suitable for any type of electric battery 4, such as a lithium-ion battery or other. It should be noted that the charging device 1 is also particularly suitable for recharging a sodium battery that can accept very high charging currents, for example, between 2500 A and 3500 A.

[0019] The charging device 1 includes at least one current source 6 and a power supply device 8 electrically connected to the current source 6. According to an embodiment described later, the charging device 1 further includes a device for regulating the temperature 10 of the electric vehicle battery during its charging.

[0020] The current source 6 can be of any type suitable for charging a battery of electric vehicle. According to one embodiment, the current source 6 is more particularly arranged to deliver a current with a high intensity, for example up to 3500 A.

[0021] The power supply device 8 includes at least one arm 12 carrying, at one of its ends, a connection device 14 electrically connected to the current source 6. More particularly, the arm 12 extends between an actuation end connected to an actuation device 16 and a free end carrying the connection device 14. The arm 14 is translationally movable so as to be able to move the connection device 14, as will be described later.

[0022] The power supply device 8, and optionally the current source 6, are mounted in a storage volume 20. According to an embodiment shown in Figs. 1, 5 and 6, the storage volume 20 extends under a floor 22 of the charging device, the floor being arranged to receive the electric vehicle 2 during the charging of its battery 4.

[0023] Such a floor 22 can be formed by the floor of a charging station accommodating electric vehicles to be charged, in which case the storage volume 20 is, for example, formed by a box embedded in the floor. Alternatively, the floor 22 is formed by a platform on which an electric vehicle is positioned to be charged, and the storage volume extends inside the platform beneath the vehicle's reception surface. Thus, when the storage volume 20 extends beneath a floor 22, both the storage volume 20 and the power supply device 8 extend beneath the electric vehicle received on the floor 22 for charging.In an alternative not shown, the storage volume 20 may be provided in a wall, for example of a charging station or building, adjacent to the electric vehicle 2 to be charged, in which case the storage volume 20 and the power supply device 8 are provided on one side of the vehicle when it is received on the floor 22 to be charged.

[0024] The storage volume 20 is, for example, closed by at least one flap 24, or damper, when the charging device is not in use. The flap 24 is movable relative to the storage volume 20 between a closed position (Fig. 1), in which the flap 24 closes the storage volume 20, and an open position (Figs. 5 and 6), in which the flap 24 provides access from the outside to the storage volume 20. More specifically, when the storage volume 20 extends under a floor 22, the flap 24 in the open position provides access to the storage volume 20 from the top of the floor 22, which then includes a through-opening opposite the storage volume 20. Thus, according to this embodiment, the flap 24 also closes the through-opening of the floor 22 in the closed position. The flap 24 is, for example, sliding under the floor 22 between the closed and open positions.

[0025] The arm 12 is movable in translation relative to the storage volume 20 between a In a retracted position (Figs. 1 and 5), the arm 12 and the connection device 14 extend inside the storage volume 20, and in an extended position (Fig. 6), the connection device 14 extends outside the storage volume 20 to be brought closer to the electric vehicle to be charged. More specifically, when the storage volume 20 extends under the floor 22, the connection device 14 projects from the floor 22 above it in the deployed position of the arm 12. In other words, the arm 12 then passes through the through-opening in the floor 22 to bring the connection device 14 closer to the electric vehicle to be charged. When the storage volume 20 extends into a wall, the connection device 14 projects from the wall to the outside to be brought closer to the electric vehicle to be charged.The arm 12 moves from the retracted position to the deployed position when the flap 24 is in the open position and when a vehicle is positioned on the floor 22. The movement of the arm 12 is actuated by the actuating device 16, as will be described in more detail later.

[0026] The connection device 14 is arranged to be electrically connected to a supplementary connection device 26 of the electric vehicle 2 when the arm 12 is in the deployed position, as shown in [Fig. 6], so as to transmit an electric current from the current source 6 to the supplementary connection device 26. The supplementary connection device 26 is electrically connected to the battery 4 of the electric vehicle 2 so that this current is transmitted to the battery 4 in order to recharge it, in a known manner. The supplementary connection device 26 therefore extends alongside the connection device 14 when the electric vehicle 2 is positioned on the floor 22 and is accessible from outside the electric vehicle 2 so that the connection device 14 can make contact with it in the deployed position of the arm 12.Thus, when the storage volume 20 extends under the floor 22, the supplementary connection device 26 is accessible from a floor 28 of the electric vehicle 2. More specifically, the supplementary connection device 26 extends, for example, into the floor 28 of the electric vehicle 2, as shown in [Fig. 2]. When the storage volume 20 extends into a wall, the supplementary connection device 26 is accessible, for example, from a side of the electric vehicle 2, for example, at the front or rear.

[0027] When the electric vehicle 2 is not being charged, the supplementary connection device 26 is, for example, made inaccessible from outside the vehicle by being closed by a flap 30. Such a flap 30, for example provided in the floor 28 of the electric vehicle when the storage volume 20 extends under the floor 22, is then movable between a closed position (not shown), in which the supplementary connection device 26 is inaccessible from outside the vehicle, and an open position (Figs. 1, 5 and 6), in which the flap 30 provides access to the auxiliary connection device 26 from outside the vehicle. The movement of the flap 30 between the closed and open positions is, for example, electrically or hydraulically controlled by the electric vehicle. In one embodiment, the flap 30 moves from the closed position to the open position only when the electric vehicle 2 is approaching the charging station or is on the floor 22 of the charging station. The rest of the time, the flap 30 is closed so as to make the auxiliary connection device 26 inaccessible and to protect it.

[0028] The connection device 14 and the complementary connection device 26 are arranged to ensure an electrical connection between them by pressing the connection device 14 against the complementary connection device 26, i.e. without mechanical connection between the connection device 14 and the complementary connection device 26. By "without mechanical connection", it is understood that the electrical connection between the connection device 14 and the complementary connection device 26 does not require the insertion of a male element into a female element, as is the case with a traditional electrical plug for example.

[0029] To this end, the connection device 14 includes at least one connection pin 32 arranged to be applied against the supplementary connection device 26 when the arm 12 is in the deployed position, as shown in [Fig. 6]. More specifically, the connection pin 32 is arranged to be applied against a pad 34 of the supplementary connection device, this application ensuring the passage of current between the connection pin 32, electrically connected to the current source 6, and the pad 34, electrically connected to the battery 4 of the electric vehicle.

[0030] The connection pin 32, for example, has a contact surface with the supplementary connection device 26 that is larger than the surface strictly necessary to ensure current transmission through the contact between the connection pin 32 and the supplementary connection device 26. Thus, even if the connection pin 32 and the supplementary connection device 26 are not perfectly aligned with each other, current transmission from the current source 6 to the electric battery 4 occurs as long as at least part of the connection pin 32 is pressed against the supplementary connection device 26. In other words, the electric vehicle 2 does not need to be positioned very precisely relative to the arm 12 for the charging device to function, as is the case when the electrical connection requires a mechanical connection.Advantageously, the pad 34 of the complementary connection device 26 also has a contact surface with the connection pin 32 su. greater than the surface strictly necessary to ensure current transmission through contact between the connecting pin 32 and the pad 34 of the complementary connecting device 26. Such an embodiment further reduces the positioning accuracy required for the electric vehicle 2 with respect to the arm 12. It should be noted that, since the position of the arm 12 does not need to be changed to ensure precise alignment between the connecting device 14 and the complementary connecting device 26, the arm 12 only needs to be movable in one direction between the retracted and deployed positions, which simplifies the structure of the power supply device 8.

[0031] According to one embodiment, the connection device 14 comprises a positive connection pin 38, electrically connected to a positive terminal of the current source 6, and a negative connection pin 40, electrically connected to a negative terminal of the current source 6. The arm 12 then moves the positive connection pin 38 and the negative connection pin 40 between the retracted and extended positions. Similarly, according to this embodiment, the complementary connection device comprises, for example, a positive pad 42, electrically connected to a positive terminal of the battery 4, and a negative pad 44, electrically connected to a negative terminal of the battery 4.At least a portion of the positive connection pin 38 is then in contact with at least a portion of the positive pad 42 and at least a portion of the negative connection pin 40 is in contact with at least a portion of the negative pad 44 when the arm 12 is in the deployed position and the electric vehicle 2 is received on the floor 22, as shown in [Fig. 6]. Alternatively, the power supply device 8 may comprise two arms 12, each carrying one of the positive and one of the negative pins.

[0032] It is understood that the power supply 8 may also include a grounding pin, allowing the electrical circuit formed by the connection between the connection device 14 and the complementary connection device 26 to be grounded. The complementary connection device 26 then includes a corresponding pad, and the operation of the connection between the grounding pin and the corresponding pad is the same as that described in relation to the positive and negative connection pins and the corresponding pads. It is also understood that the power supply 8 may be used to transmit control signals between the charging device and the vehicle being charged, for example, by establishing a dedicated connection according to the same principle as described above when the arm 12 moves into the deployed position.Alternatively, the connection can be "wireless" and use contactless communication protocols, for example Bluetooth® or others.

[0033] As previously stated, the charging device 1 further comprises, according to In one embodiment, a temperature control device 10 regulates the temperature of the battery 4 during its charging, that is, when the connection device 14 is electrically connected to the supplementary connection device 26. This temperature control device 10 is arranged to cool the cells of the battery 4 during charging to prevent overheating of the battery 4 when current from the power source 6 is supplied to it. In one embodiment, the temperature control device 10 can also be arranged to increase the temperature of the cells of the battery 4, for example, before charging begins, which can help optimize the charging time of the battery 4.

[0034] The control device 10 comprises a control fluid source 46 and at least one control fluid inlet 48 in fluidic communication with the fluid source 46. The control fluid is, for example, a gas or a liquid, such as air or water. Alternatively, the control fluid is a heat-generating gas or liquid, i.e., it has a higher heat capacity than air or water.

[0035] The inlet pipe 48 includes a connection fitting 50 to an inlet 52 of a temperature control circuit 54 of the electric battery 4 of the electric vehicle 2. According to one embodiment, the control fluid is injected into the control circuit 54 in order to circulate the control fluid from the control fluid source 46 into the control circuit 54 when the connection fitting 50 is connected to the inlet 52 of the control circuit 54.

[0036] The inlet pipe 48 and optionally the regulating fluid source 46 are housed within the storage volume 20, and the inlet pipe 48 is movable relative to the storage volume 20 between a retracted position ([Fig. 1]), in which the inlet pipe 48 and the connecting fitting 50 extend into the storage volume 20, and an extended position (Figs. 4 to 6), in which at least the connecting fitting 50 extends outside the storage volume 20 and is connectable to the inlet 52 of the regulating circuit 54. More specifically, when the storage volume 20 extends below the floor 22, the connecting fitting 50 projects from the floor 22 above it in the extended position of the inlet pipe 48. In other words, the inlet pipe 48 then passes through the through opening from floor 22 to bring the connection fitting of the inlet 52 closer to the regulation circuit 54.When the storage volume 20 extends into a wall, the connection fitting 50 projects outward from the wall to bring it closer to the electric vehicle 2 to be charged. The inlet pipe 48 moves from the retracted to the extended position when the flap 24 is in the open position and when a vehicle is positioned on the floor 22. The movement of the inlet pipe 46 is actuated by an actuation device 56, as will be shown. described in more detail later.

[0037] According to one embodiment, the control circuit 54, into which the inlet pipe 48 injects the control fluid, is also the vehicle's control circuit, used when the vehicle is in motion. Such a control circuit is, for example, closed inside the vehicle. In this case, the connection fitting 50 can be arranged to simply be placed in contact with the inlet 52 to effect heat exchange between the control fluid circulating in the electric vehicle's control circuit 2 and the control fluid circulating in the inlet pipe 48. Alternatively, the connection fitting 50 and the inlet 52 can be arranged so that the control fluid from the fluid source 46 is injected into the control circuit 54.

[0038] According to a preferred embodiment shown in [Fig. 4], the control circuit 54 is separate from the isolated control circuit 58 inside the vehicle and is only used during the charging of the battery 4 of the electric vehicle 2. In this case, the control device 10 further includes an outlet line 60 of the control fluid comprising a connection fitting 62 to an outlet 64 of the control circuit 54. The outlet line 60 is, for example, in fluidic communication with the control fluid source 46.

[0039] In this case, the outlet pipe 60 is also movable, for example with the inlet pipe 48, between a retracted position ([Fig. 1]), in which the outlet pipe 60 and the connection fitting 62 extend into the storage volume 20, and a deployed position (Figs. 4 to 6), in which at least the connection fitting 62 extends outside the storage volume 20 and is connectable to the outlet 64 of the control circuit 54. Thus, according to this embodiment, the control fluid from the fluid source 46 is injected into the control circuit 54 through the inlet pipe 48 and its connection fitting 50, circulates in the control circuit 54 to cool or heat the cells of the battery 4, and leaves the control circuit 54 through the outlet pipe 60 and its connection fitting 62, for example to return to the fluid source 46.When the electric vehicle 2 is not charging and is operating outside the charging device, the control circuit 54 is, for example, empty, i.e., it does not contain any regulating fluid, the temperature regulation of the battery 4 then being carried out by the isolated control circuit 58. In this case, the control circuit 54 is, for example, under a gaseous vacuum or under an air pressure greater than 1 bar.

[0040] The control circuit 54, for example, has a shape arranged so that the control fluid circulates around each cell of the battery 4 of the electric vehicle 2. According to one embodiment, each battery cell includes an integrated fluid circuit forming part of the control circuit 54 in order to allow Heat extraction is performed within each cell. In one embodiment, the control circuit 54 does not include any branches, meaning that the control fluid flows directly from the inlet 52 to the outlet 64 without being distributed among different branches of the circuit. Alternatively, the control circuit 54 includes one or more branches between the inlet 52 and the outlet 64 in order to parallelize the temperature regulation of the cells and thus optimize the temperature regulation of the battery 4. In this case, the cross-section of the pipes forming the control circuit 54 is, for example, variable to ensure homogeneous circulation of the control fluid in all branches of the control circuit 54.Solenoid valves or equivalent may be provided to control the circulation of the regulating fluid in the different branches of the regulating circuit 54 for example in order to optimize the heat extraction from the cells according to strategies and prioritizations of charging the cells of battery 4.

[0041] According to one embodiment, the charging device further comprises a receiving device 66 for at least one wheel 68 of the electric vehicle 2 to ensure the positioning of the electric vehicle 2 within the charging device. Thus, the storage volume 20 is positioned relative to the receiving device 66 such that the supplementary connection device 26 of the electric vehicle 2 extends in relation to the storage volume 20 when the wheel 68 is received in the receiving device 66, as shown in Figs. 1, 5, and 6. It is understood, however, that since the embodiment of the connection device 14 in the form of at least one connecting pin 32 makes it possible to ensure an electrical connection with the supplementary connection device 26 without requiring a mechanical connection, the positioning of the receiving device 66 relative to the storage volume 20 does not need to be very precise.According to one embodiment, the receiving device 66 is arranged to receive two wheels 68 of the electric vehicle 2, for example the front wheels of the vehicle, as shown in Figs. 2 and 3.

[0042] In one embodiment, the actuating device 16 of the arm(s) 12 is, for example, connected to the receiving device 66 so that the arm(s) 12 move to the deployed position only when a wheel 68 is received in the receiving device 66. In a particular embodiment, the actuating device 16 of the arm(s) 12 can be arranged to move the arm(s) 12 to the deployed position by means of the weight of the wheel 68 received in the receiving device. Thus, the actuating device 16 does not require any other energy source to move the arm(s) 12. Alternatively or in addition, the actuating device 56 of the inlet and outlet pipe(s) of the control device 10 can also be connected to the receiving device 66 to allow and / or trigger the movement of the pipe(s) from the retracted position to the extended position. deployed. Similarly, the flap 24 can be arranged to be moved from the closed position to the open position when a wheel 68 is received in the receiving device 66.

[0043] The charging device described above allows for the rapid and simple charging of the battery 4 of an electric vehicle 2. In particular, the charging device does not require operator intervention and is compatible with the passage of a high-intensity electric current, thus enabling the rapid charging of a battery 4, especially a sodium battery. When the storage volume 20 is located under the floor 22 and the additional connection device 26 is accessible from below the floor 28 of the electric vehicle 2, the entire charging device is inaccessible to persons around the vehicle, making this charging device safe to use. When no electric vehicle 2 is on the floor 22, the power supply device 8 remains inaccessible from the outside by means of a cover 24.
