FLUID GUIDING DEVICE FOR GUIDING A FLUID IN A CHARGING STATION AND CHARGING STATION WITH SUCH A FLUID GUIDING DEVICE

Description

[0001] The invention relates to a fluid guidance device for guiding a fluid in a charging station and a charging station with at least one electronic module and at least one such fluid guidance device.

[0002] Advances in battery storage technology enable higher electrical capacity while maintaining the same physical size. This allows electric vehicles to be equipped with batteries of higher electrical capacity. Electric vehicle users typically expect rapid charging so they can continue driving promptly and are therefore not necessarily willing to spend more time at the charging station simply because of a larger battery capacity.

[0003] Therefore, it is necessary to increase the charging power for charging the battery storage system. Increasing the charging power primarily involves increasing the charging current and / or charging voltage. The heat generated in the charging station, particularly by electronic modules, especially the power electronics, is typically dissipated by a cooling system within the charging station. For cooling the power electronics, a fluid cooled by the cooling system is usually conveyed through a fluid pump and distributed throughout the charging station by means of a fluid guide. Such a fluid guide typically has a complex flow path to ensure the fluid reaches all electronic modules requiring cooling. Due to this complex flow path, such a fluid guide usually occupies a significant amount of installation space within the charging station.

[0004] The fluid is typically conveyed to the cooling circuit of the electronic module via the fluid guide device. If such an electronic module fails, its cooling circuit must be disconnected from the fluid guide device and removed from the charging station. This can lead to a partial leakage of the fluid contained in the electronic module's cooling circuit, causing it to unintentionally enter the charging station and potentially damage electronic components. When the module is reinserted into the charging station, the electronic module's cooling circuit must be reconnected to the fluid guide device in a flow-optimized and leak-free manner. Particularly due to manufacturing inaccuracies or imprecise positioning of the connections, establishing a flow-optimized connection between the electronic module's cooling circuit and the fluid guide device is not always straightforward.

[0005] CN 114 242 328 A discloses a liquid cooling source for cooling a charging plug and a charging cable of a charging station. US 2021 / 387536 Al relates to a fluid guidance device for guiding a fluid in a charging station according to the prior art.

[0006] The invention is therefore based on the objective of creating a fluid guidance device for guiding a fluid in a charging station and a charging station with at least one electronic module and at least one such fluid guidance device, wherein the aforementioned disadvantages are reduced, preferably do not occur.

[0007] The problem is solved by providing the present technical teaching, in particular the teaching of the independent claims as well as the preferred embodiments disclosed in the dependent claims and the description.

[0008] The problem is solved, in particular, by providing a fluid guidance device for guiding a fluid in a charging station. The fluid guidance device has a longitudinal channel extending in a longitudinal direction, with at least two first fluid connections extending transversely to the longitudinal direction arranged along the longitudinal channel. At least one second fluid connection is arranged at a first end of the longitudinal channel. The longitudinal channel is closed at a second end opposite the first end.The longitudinal channel connects the at least two first fluid connections in a flow-parallel manner to the at least one second fluid connection, wherein the longitudinal channel is designed to be deformable, and wherein the longitudinal channel and at least one first fluid connection, selected from the at least two first fluid connections, form a bearing recess, the bearing recess being designed to support the fluid guide device in the charging station. In this way, a particularly compact fluid guide device is advantageously provided, which can be arranged in a space-saving manner in a charging station. By designing the fluid guide device as a longitudinal channel, it is particularly possible to convey the fluid within the fluid guide device in a space-saving manner to just in front of an electronic module of the charging station.This eliminates unnecessary connection points, thereby reducing, and preferably preventing, the risk of leakage.

[0009] The fluid is in particular an air conditioning fluid, in particular a cooling fluid, in particular water, in particular a water-glycol mixture.

[0010] In one embodiment, the longitudinal channel extending in a longitudinal direction has, in particular, a rectangular profile with its longer side oriented transversely to the longitudinal direction, or is formed by such a profile. In particular, the edges of the longitudinal channel that are parallel to the longitudinal direction – the corners of the rectangular profile – are rounded.

[0011] In another embodiment, the longitudinal channel extending in a longitudinal direction has, in particular, a circular or elliptical profile in cross-section, or is formed by such a profile. If the profile is elliptical, its principal axis is preferably oriented transversely to the longitudinal direction.

[0012] In particular, the longitudinal channel is shaped like a lance or lance-like.

[0013] In electrical engineering, a charging station is any device or electrical system, particularly stationary or mobile, that serves to supply energy to mobile battery-powered devices, machines, or motor vehicles simply by placing them on the charging station or plugging them in, without necessarily having to remove the energy storage device—such as the traction battery of an electric car. Charging stations for electric cars are sometimes also called "electric vehicle charging stations" and can include multiple charging points. Particularly well-known are direct current fast charging systems (high-performance charging systems or high-power charging systems, HPC systems), such as the combined charging system (CCS), which is widespread in Europe.In conventional DC charging, direct current from the charging station is fed directly into the vehicle's battery. This is achieved by a high-performance rectifier, preferably located in the charging station, supplied by the power grid or by large buffer batteries at, for example, solar charging stations. The vehicle contains a battery management system that communicates directly or indirectly with the charging station to adjust the current and voltage or to terminate the charging process when a predetermined capacity limit is reached. The power electronics are typically located in the charging station. Because the DC connections of the charging station are directly connected to the corresponding terminals of the traction battery—without the need for an AC / DC converter in the vehicle—high charging currents can be transmitted with minimal loss, resulting in short charging times.

[0014] In one embodiment, the charging station is designed as a charging column. In particular, the charging station has at least one charging point, especially exactly one charging point or exactly two charging points.

[0015] In particular, the charging station is designed as a fast charging station. In one embodiment, the charging station is designed as a battery-powered charging station, specifically as a battery-powered fast charging station.

[0016] According to the invention, the longitudinal channel is designed to be deformable. This advantageously compensates for manufacturing inaccuracies and / or inaccurate positioning of connections corresponding to the longitudinal channel on a charging station or even the fluid connections themselves. In particular, this makes it possible to easily arrange an electronic module in the charging station and establish a fluid-flow connection.

[0017] In another example, the longitudinal channel is rigidly designed. This makes it particularly easy to insert the longitudinal channel – especially from one side or end – into a charging station.

[0018] In the context of this technical teaching, the fact that the longitudinal channel is designed to be deformable means, in particular, that its length can be changed, specifically that it can be compressed and / or stretched along its longitudinal direction. Alternatively or additionally, the longitudinal channel can be curved. In particular, the longitudinal channel is deformable in a repeatable manner, especially non-destructively. Specifically, the longitudinal channel is deformable by having a deformable material and / or a shape suitable for deformation. In one embodiment, the longitudinal channel has a corrugated tube or is designed as a corrugated tube.

[0019] According to a further development of the invention, the at least two first fluid connections on the longitudinal channel are detachably, in particular by being screwed on and / or pulled off. This makes it particularly easy to replace a defective fluid connection or to replace it with a fluid connection with a different connection diameter, in particular by screwing it on or pushing it on.

[0020] According to the invention, the longitudinal channel and at least one first fluid connection, selected from the at least two first fluid connections, form a bearing recess, in particular a groove, wherein the bearing recess is configured to support the fluid guide device in the charging station, in particular optionally in a displaceable or non-displaceable manner relative to a housing of the charging station. In this way, a particularly compact design of the fluid guide device is advantageously achieved. In particular, the fluid guide device eliminates the need for additional fastening elements by means of which the fluid guide device can be attached to a charging station, since the bearing recess is formed as a fastening element by the fluid guide device itself.

[0021] The disclosure also includes a fluid guidance arrangement comprising a first fluid guidance device with a rigid longitudinal channel, and a second fluid guidance device with a deformable longitudinal channel, arranged in particular parallel to the first fluid guidance device.

[0022] The problem is also solved by creating a charging station with at least one electronic module and at least two fluid guide devices according to the invention or fluid guide devices according to one or more of the embodiments described above. The charging station has a first fluid guide device of the at least two fluid guide devices as a fluid supply device. The fluid supply device has at least two fluid outlet ports as its at least two first fluid connections. One fluid outlet port of the at least two fluid outlet ports is detachably connected to a fluid circuit inlet port, in particular a cooling circuit inlet port, of the at least one electronic module, in particular a power electronics module. The charging station has a second fluid guide device of the at least two fluid guide devices as a fluid discharge device.The fluid discharge device has at least two fluid inlet connections as its at least two first fluid connections. One of the at least two fluid inlet connections is detachably connected to a fluid circuit outlet connection, in particular a cooling circuit outlet connection, of the at least one electronic module, especially the power electronics. A fluid guide device, selected from the fluid discharge device and the fluid supply device, has a deformable longitudinal channel. In connection with the charging station, the advantages that have already been explained in connection with the fluid guide device become particularly apparent.

[0023] In one embodiment, the other fluid guidance device, selected from the fluid supply device and the fluid discharge device, has a rigid longitudinal channel. In particular, the charging station has a fluid guidance arrangement according to the invention or a fluid guidance arrangement according to one or more of the embodiments described above.

[0024] In particular, a further fluid output connection of the at least two fluid output connections is detachably connected to a fluid circuit input connection, in particular a cooling circuit input connection, of a further electronic module of the charging station, in particular a further power electronics module.

[0025] In particular, a further fluid inlet connection of the at least two fluid inlet connections is detachably connected to a fluid circuit outlet connection, in particular a cooling circuit outlet connection, of the further electronic module, in particular the further power electronics.

[0026] In particular, the fluid flows through the fluid supply device and from there through the respective fluid outlet port into the associated fluid circuit inlet port, flows from there through the associated electronic module to cool it, exits the module again through the associated fluid circuit outlet port, and enters the fluid discharge device through the associated fluid inlet port and continues flowing through it. Using the first two fluid ports of each fluid guide device, two separate electronic modules, or alternatively a larger electronic module, can be supplied with fluid in this way.

[0027] According to a further development of the invention, at least one fluid connection, in particular each of the fluid connections selected from the at least two fluid outlet connections and the at least two fluid inlet connections, has a connector receptacle. A fluid circuit connection associated with the fluid connection, selected from the fluid circuit inlet connection and the fluid circuit outlet connection, has a connector. The connector can be fluidically connected to the connector receptacle by detachably inserting the connector into the connector receptacle. The connector is designed in such a way that it is fluid-tight when the connector is detached from the connector receptacle. In this way, a fluid connection between the fluid connection and the fluid circuit connection is advantageously established and disconnected particularly easily.In particular, it is possible to disconnect and reconnect a fluid-flow connection without dripping. This significantly reduces, and preferably eliminates, the risk of leakage. Specifically, the electronic module is not damaged by any leaked fluid.

[0028] The plug receptacle has a cup shape or is cup-shaped.

[0029] In particular, the connector is designed to establish a fluid connection between the fluid port and the associated fluid circuit port when inserted, especially when plugged in, especially when pressed into the connector receptacle. The connector is designed such that the fluid connection is broken again when the connector is disconnected.

[0030] According to a further development of the invention, the bearing recess of a fixed fluid guide device, selected from the fluid supply device and the fluid discharge device, interacts with a first opening in the wall of the charging station, such that a fixed fluid connection of the at least two first fluid connections of the fixed fluid guide device is fixed in the charging station, i.e., in particular, fixed without displacement or rigidly attached, especially clamped. A first fluid path is formed from the longitudinal channel of the fixed fluid guide device to the fixed fluid connection, wherein the first fluid path is guided through the first opening. In particular, both first fluid connections of the fixed fluid guide device are fixed in this manner.The mounting recess of a movable fluid guide device, selected from the fluid supply device and the fluid discharge device, interacts with a second opening in the wall of the loading station, such that a movable fluid connection of the at least two first fluid connections of the movable fluid guide device is movable, and in particular floating, within the loading station. A second fluid path is formed from the longitudinal channel of the movable fluid guide device to the movable fluid connection, the second fluid path passing through the second opening. In particular, both first fluid connections of the movable fluid guide device are movable, and in particular floating, in this way. Alternatively, one of the first fluid connections of the movable fluid guide device is movable, and the other is rigidly fixed.In particular, the fixed fluid guide device is advantageously attached to the charging station by means of a type of fixed bearing, and the movable fluid guide device is attached to the charging station by means of a type of floating bearing. The movable design of the movable fluid guide device allows for compensation of manufacturing inaccuracies and inaccurate positioning of the connections.

[0031] In the context of this technical teaching, the fact that a movable fluid connection of the at least two first fluid connections of the movable fluid guide device is movably mounted in the charging station means, in particular, that the movable fluid connection is movably mounted, especially floatingly, in a plane arranged parallel to the wall. In particular, the movable fluid connection is movable relative to the wall of the charging station. In particular, the movable fluid connection is movable relative to another movable or fixed fluid connection of the at least two first fluid connections of the movable fluid guide device. In particular, the movable fluid connection of the movable fluid guide device is movable relative to a fixed fluid connection of the fixed fluid guide device.

[0032] According to a further development of the invention, a sliding element, in particular a sliding ring, especially a plastic ring, is arranged between the movable fluid connection of the movable fluid guide device and the wall. This makes moving the movable fluid guide device particularly easy.

[0033] According to a further development of the invention, the charging station comprises an electronics section and a fluid section. The wall is arranged between the electronics section and the fluid section. The electronic module, in particular the power electronics, is located in the electronics section. The fluid supply device and the fluid discharge device are located in the fluid section. In this way, the charging station can be operated particularly safely and reliably, since a spatial separation between the electronics section and the fluid section is achieved. In particular, condensation does not form on the fluid guide device in the electronics section, as this device is located in the spatially separated fluid section.

[0034] In particular, the fluid compartment is arranged geodesically below the electronics compartment. This prevents any fluid that may escape from the fluid compartment from flowing into the electronics compartment. Alternatively or additionally, the wall separating or demarcating the fluid compartment from the electronics compartment is horizontally oriented. In particular, the electronics compartment is arranged above the horizontal wall, and the fluid compartment is arranged below the horizontal wall.

[0035] According to a further development of the invention, the charging station comprises a heat storage device and an air conditioning device. The fluid supply device has two secondary fluid connections as at least one secondary fluid connection: a heat storage device inlet as a first secondary fluid connection and an air conditioning device outlet as a second secondary fluid connection. The heat storage device inlet is fluidically connected to the heat storage device, and the air conditioning device outlet is fluidically connected to an inlet of the air conditioning device. The fluid discharge device has two secondary fluid connections as at least one secondary fluid connection: a heat storage device outlet as a first secondary fluid connection and an air conditioning device inlet as a second secondary fluid connection.The heat storage device outlet is fluidically connected to the heat storage device, and the air conditioning device inlet is fluidically connected to an outlet of the air conditioning device. This advantageously results in a particularly simple and space-saving flow path within the charging station. It also eliminates the need for additional pipes and valves.

[0036] The heat storage device is, in particular, a container or tank for the fluid. In particular, the heat storage device is insulated, especially thermally insulated.

[0037] According to a further development of the invention, the two fluid outlet connections and the air conditioning device output are coordinated in such a way that a predetermined distribution of the fluid flows passing through them is achieved during operation of the charging station, which is also referred to as hydraulic balancing. In this way, additional components for carrying out the hydraulic balancing can advantageously be omitted. Furthermore, an additional balancing module for carrying out the hydraulic balancing can also be dispensed with.

[0038] Alternatively or additionally, it is provided that the two fluid inlet connections and the air conditioning device inlet are coordinated in such a way that a predetermined distribution of the fluid flows passing through the two fluid outlet connections and the air conditioning device outlet is achieved during operation of the charging station.

[0039] According to a further development of the invention, the charging station is provided with a fluid conveying device. The fluid conveying device is configured to convey a fluid from the charging station. This ensures, in particular, that a sufficient quantity of fluid is conveyed through the fluid guide device.

[0040] In particular, the fluid conveying device conveys a fluid from the heat storage device via the heat storage device inlet into the fluid supply device. Specifically, the flow here separates into three fluid flow components: A first fluid flow component flows, in particular, via the air conditioning device outlet and inlet into the air conditioning device and is cooled there. Specifically, the cooled first fluid flow component flows via the air conditioning device outlet and inlet into the fluid discharge device.

[0041] A second fluid flow component flows, in particular, from the fluid supply device via one of the fluid outlet ports and the associated fluid circuit inlet port of the associated electronic module into a fluid circuit of the electronic module. In particular, the second fluid flow component absorbs heat from the electronic module. The heated second fluid flow component then flows, in particular, via the fluid circuit outlet port of the electronic module and via one of the fluid inlet ports of the fluid discharge device into the fluid discharge device.

[0042] A third fluid flow component flows, in particular, from the fluid supply device via the other fluid outlet port and the associated fluid circuit inlet port of the associated electronic module into a fluid circuit of the electronic module. In particular, the third fluid flow component absorbs heat from the electronic module. Specifically, the heated third fluid flow component flows via the fluid circuit outlet port of the electronic module and via the other fluid inlet port of the fluid discharge device into the fluid discharge device.

[0043] The hydraulic balancing described above includes, in particular, a predetermined division between the first, second and third fluid flow components.

[0044] In particular, in the fluid discharge device, the first fluid flow component merges with the second and third fluid flow components, and the combined fluid flow flows back into the heat storage device via the heat storage device outlet.
