Description

Technical Field

[0001] The invention relates to a stationary inductive charging station for a vehicle comprising an inductive charging device. Background Art

[0002] In order to increase the acceptance of electric vehicles among end users, it may be advantageous if the energy transfer between the stationary energy source and the energy storage device of the vehicle takes place in a contactless manner. Contactless energy transfer is advantageous for the end customer because, for example, no charging cable needs to be carried or plugged in. Furthermore, stationary inductive charging stations can also be partially buried in underground areas and thus can be better integrated into the urban or natural landscape. Buried inductive charging stations are also particularly well protected against damage caused by vandalism.

[0003] A fixed inductive charging station connected to a fixed energy source is capable of generating a time-varying magnetic field via a primary-side coil. The electric vehicle has an inductive charging device comprising a secondary-side inductive coil. If the inductive charging device is located in the magnetic field area of ​​the fixed inductive charging station, the time-varying magnetic field induces an alternating current or an alternating voltage in the inductive coil of the inductive charging device, respectively. The induced alternating current or alternating voltage can be used to charge the energy storage device of the vehicle.

[0004] The efficiency of the inductive energy transfer increases with the frequency of the AC voltage applied at the primary coil. Therefore, the prior art fixed inductive charging station comprises an energy transfer module in which at least one primary-side inductive coil is arranged, and an electronic unit which converts the AC voltage supplied to the energy transfer module in a suitable manner. To this end, the electronic unit may comprise a power electronic unit which converts the supply frequency of the AC voltage, which is typically 50 Hz or 60 Hz, into a frequency range of at least 10 kHz to 200 kHz in order to ensure low-loss inductive energy transfer.

[0005] The heat energy generated by the electronic unit during operation must be dissipated in order to prevent damage to the electronic unit. To this end, the electronic unit is arranged to be spatially separated from the energy transfer module so that the heat energy of the electronic unit can be discharged to the surrounding area by air cooling.

[0006] Due to the spatial distance (usually up to 5 m or more), the high-frequency AC voltage must be transmitted to the energy transfer module via suitable cables. Due to the high frequency of the applied AC voltage, these cables must have suitable electromagnetic shielding in order to protect the surrounding area of ​​the fixed inductive charging station from unwanted interference radiation.

[0007] One disadvantage of the prior art is that electromagnetic shielding is cost-intensive and, due to air cooling, the electronic unit constitutes a source of acoustic interference. Another disadvantage is that, due to air cooling, the electronic unit must be mounted outside the driving surface, making it impossible to optically integrate the fixed inductive charging station in the natural or urban landscape. Furthermore, the accessible electronic unit may also be subject to damage caused by vandalism. Summary of the invention

[0008] The object of the present invention is to propose a stationary inductive charging station of the type mentioned above which can be produced more easily and cost-effectively, wherein the stationary inductive charging station can also be better integrated into the natural or urban landscape.

[0009] The invention is based on the general idea of ​​a spatially combined energy transfer module and an electronics unit.

[0010] The stationary inductive charging station for a vehicle with an inductive charging device according to the invention comprises an energy transfer module for contactless energy transfer and an electronic unit, wherein the energy transfer module and the electronic unit are spatially combined. The energy transfer module can be conductively connected to the electronic unit. The electronic unit can be conductively connected to an electrical energy source, such as a power grid.

[0011] The electronic unit may have a power electronic module, which may include, for example, an inverter and / or a resonant circuit and / or a power factor compensation filter (power factor compensation, abbreviated as PFC). The electronic unit may also have at least one communication module and / or a positioning module and / or a safety-related module.

[0012] The energy transfer module and the electronic unit can be combined in the housing. Spatially combined can be understood to mean that the shortest spatial distance between the electronic unit and the energy transfer module is less than 2m, in particular less than 1m. Here, the shortest spatial distance between the electronic unit and the energy transfer module can be set to be less than the sum of the maximum size of the electronic unit and the maximum size of the energy transfer module. It can be further set that the shortest spatial distance between the electronic unit and the energy transfer module is less than the maximum size of the electronic unit or the maximum size of the energy transfer module.

[0013] The energy transfer module can include at least one induction coil, which can be configured, for example, as a spiral flat coil or a double D-coil. The induction coil can be supplied with electrical energy, in particular a high-frequency AC voltage of 10 kHz to 200 kHz, via the electronics unit.

[0014] The stationary inductive charging station can have at least one magnetic conductor for conducting a magnetic field and increasing the efficiency of the energy transfer. Compared to air, the magnetic conductor has a higher magnetic permeability and can be made at least partially of a ferrimagnetic and / or ferromagnetic material. The magnetic conductor can consist of one plate element or also of a plurality of plate elements.

[0015] A shielding element may be provided between the energy transfer module and the electronic unit to protect the electronic unit from electromagnetic fields. The shielding element, which may be configured as a shielding plate, may also be made of a conductive material, wherein the thickness of the shielding element may correspond to at least one skin depth that the magnetic field and the electric field may have at a given frequency of the electrical energy transfer of the conductive material of the shielding element. The shielding element may be made of aluminum, for example.

[0016] The design according to the invention of the stationary inductive charging station makes it possible to avoid the use of electrical lines with complex electromagnetic shielding.

[0017] In another advantageous embodiment of the solution according to the invention, the energy transfer module and / or the electronic unit is thermally connected via at least one heat conducting unit to a cooling element through which a fluid can flow. The cooling element through which a fluid can flow can be a cooling plate through which a fluid can flow. Such a cooling plate can have a cubic and / or plate-like design.

[0018] The cooling element can be arranged so that a fluid flows through it, cooling the cooling element through which the fluid flows.

[0019] The heat conducting unit may have a lower thermal resistance than air. The heat conducting unit may be, for example, an adhesive having a high thermal conductivity. The heat conducting unit may be a heat conducting film and / or a heat conducting paste and / or a heat conducting casting compound.

[0020] In an advantageous development of the solution according to the invention, the cooling element through which the fluid can flow is fluidically connected to the fluid circuit, wherein the fluid conveying device conveys the fluid via the fluid circuit, wherein the fluid absorbs waste heat of the inductive charging device when flowing through the cooling element. It can be provided that the fluid is a liquid, in particular it can be provided that the liquid can include water, a coolant, a refrigerant and / or oil. This provides for more efficient cooling of the stationary inductive charging station, so that the energy transfer module and the electronic unit can be arranged spatially adjacent to one another or spatially combined.

[0021] It can be provided that the cooling element has a fluid inlet and a fluid outlet, wherein the fluid inlet is fluidically connected to the fluid outlet via a flow line, wherein the fluid line passes through the cooling element.

[0022] This thermal management allows sufficient cooling of all components of the stationary inductive charging station, so that, for example, even at high charging powers, all components required for operating the stationary inductive charging station, which can be buried in the ground or also arranged above ground, can be accommodated in the same housing.

[0023] In a further advantageous embodiment of the solution according to the invention, the fluid circuit has at least one heat exchanger for dissipating the thermal energy absorbed by the fluid.

[0024] In an advantageous development of the solution according to the invention, the heat exchanger is integrated into the local heating network and / or the remote heating network, thereby enabling the generated thermal energy to be reused, for example as heat.

[0025] In a further advantageous embodiment of the solution according to the invention, the heat exchanger is designed as a liquid-air heat exchanger in order to transfer the thermal energy absorbed by the fluid to the surrounding air of the inductive charging station.

[0026] The liquid-air heat exchanger may have a cooling element through which the fluid flows, the cooling element comprising arranged cooling fins. The liquid-air heat exchanger may also have a fan unit for ensuring sufficient air circulation at the liquid-air heat exchanger or the cooling fins, respectively.

[0027] In an advantageous development of the solution according to the invention, the heat exchanger transfers the heat energy absorbed by the fluid to the surrounding area of ​​the inductive charging station. The floor or a part of a garage or parking space can be part of the surrounding area of ​​the inductive charging station, for example.

[0028] In a further advantageous embodiment of the solution according to the invention, the heat exchanger is thermally connected to a heat storage device in order to enable storage of thermal energy.

[0029] In an advantageous development of the solution according to the invention, the stationary inductive charging station has a housing which at least partially forms the cooling element in order to achieve a particularly compact design of the stationary inductive charging station. It can be provided that the housing has a fluid inlet and a fluid outlet, wherein the fluid inlet is fluidically connected to the fluid outlet via a flow-through conduit, wherein the fluid conduit runs through the housing.

[0030] It can be provided that the housing has a fluid inlet and a fluid outlet, wherein the fluid inlet is fluidically connected to the fluid outlet via the housing interior. The components of the inductive charging station that are fixed in the housing interior can be arranged such that, although a thermal connection to the fluid can be established, damage to the components is prevented by a suitable protective housing.

[0031] It can be provided that the components of the stationary inductive charging station are thermally separated from the housing by a thermal insulator, so that heat transfer to the fluid flowing through the interior of the housing is essentially carried out. The thermal insulator can be present when the thermal conductivity is less than 10 W / (mK).

[0032] All components arranged inside the housing are part of the stationary inductive charging station.

[0033] In a further advantageous embodiment of the solution according to the invention, the fluid is electrically insulating in the fluid circuit, so that short circuits due to undesired ingress of fluid into the electronics unit are avoided. Provision can be made for an electrically insulating liquid to be used as fluid.

[0034] In an advantageous development of the solution according to the invention, the stationary inductive charging station is cooled by spray cooling. A fluid, in particular a cooling medium and / or a refrigeration medium, is thereby sprayed onto the area of ​​the stationary inductive charging device to be cooled, wherein the fluid evaporates due to the absorption of energy and subsequently condenses in a condenser unit and / or a radiator (e.g. a cooling plate or the ground) by dissipating thermal energy. The condensed fluid can then be supplied again to the stationary inductive charging device. The heated fluid or cooling medium, respectively, can be condensed again at the radiator in the housing and can be used again as spray cooling.

[0035] In a further advantageous embodiment of the solution according to the invention, the stationary inductive charging station has an operating device. The operating device can be used to control and / or operate the stationary inductive charging station, wherein for this purpose the operating device can be arranged at a distance from the energy transfer module and the electronics unit. The operating device can be communicatively connected to the electronics unit. The liquid-air heat exchanger can be combined with the operating device and can comprise a part of the electronics unit.

[0036] A communication connection is to be understood here as meaning that a bidirectional or unidirectional data connection can be provided between two components connected to one another, via which electrical control, regulation and / or measurement signals can be transmitted in analog or digital form. The communication can be effected via a bus system. The communication connection can be effected via an electrical line at a typical supply frequency via the above-mentioned electromagnetic shielding. Such an electrical line can be a DC voltage line or an AC voltage line.

[0037] It can be provided that a heat exchanger, in particular a liquid-air heat exchanger, is arranged in and / or on the operating device, which heat exchanger is fluidically connected to the fluid circuit of the stationary inductive charging station.

[0038] In an advantageous development of the solution according to the invention, the stationary inductive charging station is at least partially embedded in the driving surface. It can also be provided that the stationary inductive charging station is completely buried in the driving surface. The stationary inductive charging station can thus be optimally integrated into the natural or urban landscape, wherein the inductive charging station is also particularly well protected against damage caused by vandalism.

[0039] In a further advantageous embodiment of the solution according to the invention, the stationary inductive charging station is located on the driving surface and thus provides for installation which is as simple as possible and can be used, for example, in a parking space or a garage.

[0040] According to an advantageous development of the solution according to the invention, the stationary inductive charging station is aerodynamically-acoustically optimized, so that noise radiation is reduced to a minimum.

[0041] It can also be provided that the present invention is implemented or integrated completely or at least partially on the vehicle side in a similar manner.

[0042] In an advantageous development of the solution according to the invention, the fluid is a liquid. In particular, it can be provided that the liquid can include water, a coolant, a refrigerant and / or oil. This provides for more efficient cooling of the stationary inductive charging station, so that the energy transfer module and the electronics unit can be arranged spatially adjacent to one another or spatially combined.

[0043] The cooling process can be divided into three parts, for example: 1) collecting heat and transferring it to a cooling medium; 2) transferring the heat further to a heat exchanger and the surrounding area; 3) dissipating the heat from the cooling medium to the surrounding area.

[0044] In step 2), the advantage is provided in an exemplary manner that liquid cooling requires significantly less volume per watt of cooling capacity due to the higher heat capacity. For example, the installation space required for the cooling duct can be reduced thereby, in particular significantly to less than 10% compared to air cooling. Liquid cooling also makes it possible to achieve high heat densities in individual electrical components in the case of very limited available installation space for cooling components. This makes it possible to achieve a compact design of the stationary inductive charging station.

[0045] In an advantageous development of the solution according to the invention, the fluid is enclosed in the fluid circuit relative to the surrounding area of ​​the fluid circuit and / or the fluid in the fluid circuit is fluidically separated from the surrounding area of ​​the fluid circuit. The fluid circuit may comprise a fluid line. The fluid circuit may be configured as a closed fluid circuit, in particular a closed cooling circuit. The fluid circuit may have at least one heat exchanger, in particular an air-liquid heat exchanger and / or an air-liquid coolant heat exchanger. The heat exchanger may be fluidically embedded in the fluid circuit.

[0046] The fluid, in particular the liquid coolant, can form a circulating medium which can circulate in a closed fluid circuit, in particular in a closed cooling circuit, among the components of the circuit. In other words, it can be provided that during operation of the fluid circuit, in particular during operation of the cooling circuit, the fluid, in particular the liquid coolant, is neither introduced from the outside (surrounding area) nor discharged to the outside.

[0047] In an advantageous development of the embodiment according to the invention, the local thermal resistance of the heat conducting unit varies, in particular, the local thermal resistance of the heat conducting unit varies throughout the lateral expansion. The local thermal resistance of the heat conducting unit can vary throughout the lateral expansion of the heat conducting unit.

[0048] The lateral expansion of the thermally conductive element may be aligned perpendicular to the primary functional direction of the thermally conductive element. The primary function of the thermally conductive element may be uniaxial heat conduction from the heat source to the heat sink. The lateral expansion may be described as a surface aligned perpendicular to the thermal conduction direction. Simply put, since the local vector heat flux is always aligned perpendicular to the heat sink, the lateral expansion of the thermally conductive element may be defined by the surface of the heat sink facing the heat source.

[0049] With respect to the lateral expansion of the heat conducting unit, the local thermal resistance of the heat conducting unit may form a linear change and / or a nonlinear change and / or a step change and / or an unstable change at least in a cross section.

[0050] Furthermore, it can be provided that in areas with stronger sources of heat loss (for example, greater than 5 W / cm 2 , in particular on one side of the electronic unit), the heat conduction unit has a particularly low thermal resistance, which increases the cooling capacity of this powerful local source of heat loss. It can also be provided that a material with anisotropic thermal conductivity, in particular a material with particularly high transverse thermal conductivity (e.g. graphite film) is used in the heat conduction unit. As a result, the heat flux density in the heat path to the cooling element through which the fluid can flow can be reduced, which has advantages in the technical design of the fluid guide.

[0051] Give less than 200mm 2 Especially low thermal resistances of 1000 kW / W. For particularly complex ceramic-based material bonds (e.g. silver sintering), even thermal resistances of less than 20 mm can be achieved 2 K / W value.

[0052] In an advantageous development of the solution according to the invention, the heat transfer unit is locally supplemented or replaced by an active heat pump at at least one location.

[0053] In another specific embodiment, it can be provided that one or more sources with extremely high heat loss (e.g., greater than 15 W / cm 2), the heat transfer unit is configured as an active heat transfer unit, i.e. an active heat pump. Possible embodiments of active heat pump units are known to the person skilled in the art under the terms heat pipe, thermosyphon or thermoelectric heat pump. The heat pump unit can be configured as a heat pipe, thermosyphon or also as a thermoelectric heat pump. Each active heat pump can consist of one or more heat pump units of the same or different designs. The goal of these active heat transfer units can be to improve the cooling itself (longitudinal pumping direction of the heat) and to reduce the heat flux density of very high heat loss sources (lateral pumping direction of the heat).

[0054] The longitudinal pumping direction may be a direction perpendicular to the radiator surface. The transverse pumping direction may be any direction parallel to the radiator surface. Each type of heat pump can be arranged also in combination with two pumping directions.

[0055] In an advantageous improvement of an embodiment according to the invention, the fluid is electrically insulated in the fluid circuit and flows through the housing interior of the housing, wherein the fluid at least partially wets the housing and at least some of the components in the fixed inductive charging station and / or flows directly around them and / or flows directly against them. The housing can be made of a thermally insulating material. The housing can have corresponding fluid inlets and corresponding fluid outlets so that the housing can be fluidically connected to the fluid circuit. The housing forms a housing interior space, in which the components of the fixed inductive charging station 1 are arranged. The fluid can flow through the housing interior space, wherein the fluid at least partially wets the inner surface of the housing interior space and / or flows directly around it and / or flows directly against it. The internal surface can be a surface portion of the housing that limits and / or forms the housing interior space.

[0056] In an advantageous development of the solution according to the invention, the fluid is electrically insulated in the fluid circuit and flows freely and has no further closed fluid ducts passing through the interior of the housing. The expression "flows freely and has no further closed fluid ducts" can be understood to mean that the fluid at least partially wets the inner surface of the interior of the housing and / or flows directly around it and / or flows directly against it. It can thus be provided that the guidance of the fluid in the interior of the housing is at least partially formed by the inner surface of the interior of the housing. It is thus possible to dispense with further closed fluid ducts, in particular fluid lines, formed separately from the housing. The inner surface can be a limitation of the housing and / or a surface portion forming the interior of the housing. The housing can be made of a thermally insulating material. The housing can have a corresponding fluid inlet and a corresponding fluid outlet, so that the housing can be fluidically connected to the fluid circuit. The housing can form a housing interior, in which the components of the fixed inductive charging station 1 are arranged.

[0057] It goes without saying that the features mentioned above and those yet to be described below can be used not only in the respectively specified combination but also in other combinations or alone, without departing from the scope of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0058] Preferred exemplary embodiments of the invention are illustrated in the drawings and will be described in detail in the following description, wherein the same reference numerals indicate the same or similar or functionally identical components.

[0059] The following are shown as examples:

[0060] Figure 1 shows a highly simplified illustration of a stationary inductive charging station according to the invention,

[0061] Figure 2 shows a highly simplified illustration of a stationary inductive charging station including an operating device according to the invention,

[0062] Figure 3 shows a highly simplified illustration of another embodiment of a stationary inductive charging station according to the invention,

[0063] Figure 4 A highly simplified illustration of a further embodiment of a stationary inductive charging station according to the invention is shown, which is arranged on a driving surface. DETAILED DESCRIPTION

[0064] exist Figure 1 2 shows a highly simplified schematic diagram of a stationary inductive charging station 1 according to the invention, which is buried in a driving surface 14. A vehicle 2, which can be designed, for example, as an electric vehicle or a hybrid vehicle, is located above the stationary inductive charging station 1.

[0065] The vehicle 2 has an inductive charging device 3, which has at least one secondary inductive coil, so that a contactless energy transfer can be carried out between the inductive charging device 3 and the stationary inductive charging device 1. For this purpose, the stationary inductive charging station 1 has an energy transfer module 4, which includes at least one primary-side inductive charging device, to which an AC voltage is applied. The energy transfer module 4 generates a time-varying magnetic field, which induces an AC voltage or an AC current in the inductive charging device 3, respectively, which can be applied to the energy storage device of the vehicle 2.

[0066] The stationary inductive charging station 1 comprises a housing 12, in which an energy transfer module 4, an electronic unit 5, a first heat conducting unit 6, a second heat conducting unit 6a and a cooling element 7 are arranged. The first heat conducting unit 6 is arranged between the energy transfer module 4 and the cooling element 7. The second heat conducting unit 6a is arranged between the cooling element 7 and the electronic unit 5. Due to the spatial combination of the components of the stationary inductive charging station 1, a compact and cost-effective construction can be achieved, since shielded electrical lines for the high-frequency AC voltage can be dispensed with.

[0067] The electronic unit 5 can be connected to an electrical energy source, not shown, via an electrical connection line, not shown. The electronic unit 5 is electrically conductively connected to the energy transfer module 4 and converts the electrical energy provided by the electrical energy source, not shown, before it is conveyed to the energy transfer module 4. It can be provided in particular that the electronic unit 5 has at least one power electronics module to achieve a frequency increase of the provided AC voltage. A fluid can flow through the cooling element 7, wherein the fluid in the fluid circuit 8 is conveyed by a fluid conveying device 9, which can include a fluid line 15. The fluid circuit 8 has a heat exchanger 10.

[0068] The heat energy present at the energy transfer module 4 can be transferred to the cooling element 7 via the heat transfer unit 6. The heat energy generated at the electronic unit 5 can be transferred to the cooling element body 7 via the heat transfer unit 6a. The cooling element 7 transfers the heat energy delivered to it to the fluid, which is heated when flowing through the cooling element 7. After the fluid flows out of the cooling element 7, the fluid can discharge the absorbed heat energy again into the heat exchanger 10 and thus cool down. The cooled fluid can flow into the cooling element 7 again in order to continuously remove the heat energy generated in the fixed inductive charging station 1. It can thus be provided that the fluid is a liquid.

[0069] The heat exchanger 10 can provide heat exchange between the surrounding area of ​​the stationary inductive charging station 1 and a fluid, wherein the surrounding area can be, for example, the ground of the stationary inductive charging station or the surrounding air. It is also conceivable that the heat exchanger is thermally connected to a local heating network and / or a remote heating network, so that the thermal energy generated by the stationary inductive charging station 1 can be used, for example, to heat living spaces. Since only little energy is unused, this design provides particularly high energy efficiency.

[0070] and Figure 1 compared to, Figure 2 The stationary inductive charging station 1 in FIG. 4 has an operating device 13 which is arranged spaced apart from the energy transfer module 4 and the electronic unit 5, wherein the operating device 13 can be provided to be integrated, for example, in an operating column or in a garage wall. The operating device 13 can be connected to the electronic unit 5 to communicate with the electronic unit 5 via a communication line 16, which does not have to have electromagnetic shielding.

[0071] exist Figure 2 In the embodiment, the heat exchanger 10 is thermally connected to the heat storage device 11 so that the heat energy dissipated by the fluid can be temporarily stored. Alternatively, the air heat exchanger 10 can be integrated in the operating device 13.

[0072] Figure 3 An embodiment of a stationary inductive charging station 1 is shown, in which the housing 12 forms a cooling element. In this case, the energy transfer module 4 is substantially thermally separated from the housing 12 by a first thermal insulator 17. Furthermore, the electronic unit 5 is substantially thermally separated from the housing 12 by a second thermal insulator 17a. The housing 12 can be made of a thermally insulating material. The housing 12 can have corresponding fluid inlets and corresponding fluid outlets, so that the housing 12 can be fluidically connected to the fluid circuit 8. The housing 12 forms a housing interior 18, in which the components of the stationary inductive charging station 1 are arranged. A fluid can flow through the housing interior 18, wherein the flow Figure 3 This is symbolically indicated by arrow 19. This allows a particularly compact design of the stationary inductive charging station 1. In addition, this allows heat losses to the surrounding area to be reduced, so that the amount of thermal energy that can be fed into a remote heating network, for example, can be maximized.

[0073] Figure 4 A highly simplified illustration of another embodiment of a stationary inductive charging station 1 according to the invention is shown, which is arranged on a driving surface 14. This enables a quick and cost-effective retrofit of existing driving surfaces. A vehicle 2 having an inductive charging device 3 can be supplied with electrical energy via the inductive charging station 1.
