Description

Battery housing for accommodating a high-voltage battery, motor vehicle and method for testing a battery
Technical Field
The invention relates to a battery housing for accommodating a high-voltage battery, in particular of a motor vehicle, to a motor vehicle and to a method for testing a high-voltage battery arranged in a battery housing.
Background
High-voltage batteries, in particular for motor vehicles, are typically arranged in a battery housing. During operation of the motor vehicle, strong mechanical loads (e.g., constant acceleration and braking, vibrations, etc.) act on the high-voltage battery and the battery housing. For safe operation of the high-voltage battery, it must be ensured that it is securely seated in the battery housing.
Furthermore, it is very important that the humidity in the battery case is below a critical value. In the case of excessively high humidity, the high-voltage battery may be damaged (e.g., due to a short circuit).
The opening of the battery case is closed in order to protect the high-voltage battery. However, it is disadvantageous if the high-voltage battery and the battery housing are to be tested for checks, for example, during quality control checks, during workshop stops or also during operation of the motor vehicle. In particular, due to the encapsulation of the high-voltage battery, it is only necessary to measure the humidity inside the battery housing in a complicated manner.
Disclosure of Invention
It is therefore an object of the present invention to provide a battery housing which does not have the above-mentioned disadvantages of the prior art, but which provides the possibility of detecting the humidity inside the battery housing by means of simple means.
This object is achieved by a battery housing for accommodating a high-voltage battery, in particular of a motor vehicle, wherein the battery housing has an opening, wherein the opening is closed by a closure, wherein the closure is configured such that an optical property of the closure varies depending on the degree of moisture on the inside of the closure facing the interior space of the battery housing.
The method according to the invention makes it possible to check the humidity in the interior of the battery housing without opening the battery housing. For this purpose, the already existing and subsequently closed opening of the battery housing is used. Furthermore, the humidity can be checked without mechanical contact by the change in the optical properties, which makes a quick and cost-effective check possible.
It is contemplated that the change in optical properties is accomplished by a chemical or physical process. It is conceivable for the closure to have one or more salts. It is contemplated that the change in optical properties is reversible. However, it is also conceivable that the change in the optical properties is irreversible.
Advantageous embodiments and further developments of the invention can be gathered from the following description and with reference to the drawings.
According to a preferred embodiment of the invention, it is provided that a closure for closing the opening is glued, wherein the closure is preferably an adhesive. This provides a simple possibility of closing the existing opening with low expenditure. The adhesive is preferably equivalent to the wall of the battery case with respect to mechanical and/or electrical properties (e.g., puncture resistance and/or heat resistance and/or electrical insulation).
According to a further preferred embodiment of the invention, it is provided that the closure is transparent at least to a wavelength range in the individual steep or visible range, wherein the closure is preferably transparent only when the moisture level on the inner side is below a limit value, and preferably at least to a wavelength range in the individual steep or visible range independently of the moisture level. In this way, visual inspection of the interior of the battery housing is advantageously made possible without the battery housing having to be opened.
According to a further preferred embodiment of the invention, it is provided that the closure is retroreflective (retroreflektiv) at least for individual wavelengths or wavelength ranges in the visible range, wherein the closure is preferably only retroreflective when the moisture level on the inner side is below a limit value or when the moisture level on the inner side is above a limit value. This makes it possible to find the closure easily and reliably, in particular during an automated and camera-assisted audit. The risk of not being able to find a (semi-) transparent closure automatically can thus be significantly reduced.
According to a further preferred embodiment of the invention, it is provided that the closure is UV-active, wherein the closure is preferably UV-active only when the moisture level on the inner side is below a limit value or when the moisture level on the inner side is above a limit value. The discoverability of the closure during the automated and camera-assisted audit is thereby likewise improved. For this purpose, UV light sources can also be used and the illumination of the closure can be achieved by means of these UV light sources.
According to another preferred embodiment of the invention, it is provided that the change in the optical property comprises a change in the retroreflectivity of the enclosed portion. In an advantageous manner, a rapid and reliable sensing of the moisture level in the battery housing can thereby be achieved in an automated and, for example, camera-assisted manner. It is conceivable that the retroreflectivity varies with respect to the intensity of the reflected light or with respect to the wavelength range for which the enclosed portion is retroreflective.
According to another preferred embodiment of the invention, it is provided that the change in the optical property comprises a change in the color of the closure portion. This makes it possible to reliably and simply check the humidity in the battery housing, for example with the naked eye, in a test arrangement which does not require a high outlay.
According to another preferred embodiment of the invention, it is provided that the change in the optical property comprises a change in the UV activity of the closing section. In an advantageous manner, a rapid and reliable detection of the moisture level in the battery housing can thereby be achieved in an automated and, for example, camera-assisted manner. It is conceivable that the UV activity varies with respect to the intensity of the emitted light or with respect to the wavelength range of the emitted light or UV light which induces the UV activity.
In order to achieve the object defined in the opening paragraph, a further subject matter of the invention is a motor vehicle having a battery housing according to the invention.
In order to achieve the object described in the opening paragraph, a further subject matter of the invention is a method for checking a high-voltage battery arranged in a battery housing, wherein a moisture level contained in the battery housing is determined by means of an optical property of a closure which closes an opening of the battery housing. The method according to the invention allows a simple and rapid check of the moisture level in the battery housing within the scope of an audit, a workshop stop or during the operation of the high-voltage battery, without the battery housing having to be opened for this purpose. In an advantageous manner, openings in the battery housing are used, which openings have been closed by a closure for operating the high-voltage battery.
According to a further preferred embodiment of the invention, it is provided that the spatial arrangement of the high-voltage battery in the battery housing is determined visually by the closure. In this case, it is preferably provided that the closure is transparent at least to individual wavelengths or wavelength ranges, particularly preferably to wavelength ranges in the visible range.
According to a further preferred embodiment of the invention, it is provided that the optical property comprises the degree of retroreflectivity of the closure. In an advantageous manner, rapid and reliable sensing of the humidity in the battery housing can thereby be achieved in an automated and, for example, camera-assisted manner. It is conceivable that the retroreflectivity varies with respect to the intensity of the reflected light or with respect to the wavelength range for which the enclosed portion is retroreflective.
According to a further preferred embodiment of the invention, it is provided that the optical property includes the degree of UV activity of the closing section. In this way, it is likewise advantageously possible to detect the moisture level in the battery housing quickly and reliably in an automated and, for example, camera-assisted manner. It is conceivable that the UV activity varies with respect to the intensity of the emitted light or with respect to the wavelength range of the emitted light or UV light which induces the UV activity.
According to a further preferred embodiment of the invention, it is provided that the optical property comprises a color of the closure. This makes it possible to reliably and simply check the humidity in the battery housing, for example with the naked eye, in a test arrangement which does not require a high outlay.
According to a further preferred embodiment of the invention, it is provided that the optical property and preferably the spatial arrangement of the high-voltage battery in the battery housing are detected by means of a camera.
Another subject of the invention is a method for detecting the spatial arrangement of a component of a motor vehicle and for sealing the component, wherein an opening of the component is closed with a retroreflective closure, wherein a light emitter illuminates the closure with light and a camera detects the light reflected from the closure. A very reliable and smooth detection of the spatial arrangement can be achieved by the retroreflectivity. The component can be, for example, a battery housing, preferably a battery housing according to the invention. The component can however also be other parts of a motor vehicle, for example a body component.
According to a further preferred embodiment of the invention, it is provided that the sealing and the detection of the spatial arrangement are used within the scope of a process step of the production of the motor vehicle, wherein the component, in particular a body component, and/or the process step, in particular, comprises a painting method.

Detailed Description
Fig. 1 schematically illustrates a battery case 1 according to an exemplary embodiment of the present invention and a method according to an exemplary embodiment of the present invention. The battery case 1 is a battery case 1 of a motor vehicle (see fig. 2). In the battery housing 1, a high-voltage battery 2 is arranged, which is used, for example, to supply voltage or current to an electric machine for driving a motor vehicle.
The opening 3 of the battery housing 1 is closed by a closure 4 (here by means of an adhesive). The closing part 4 is transparent at least for the respective wavelength ranges in the visible range, so that inspection of the interior space 5 of the battery case 1 can be achieved by the closing part 4. In order to ensure a better mechanical protection of the high-voltage battery 1, the closure 4 is embodied to be robust and tear-and puncture-resistant.
In order to be able to determine the moisture level in the interior 5 of the battery housing 1 without opening the battery housing 1, the closure 4 changes at least one optical property depending on its moisture level on the inside 6 facing the interior 5 of the battery housing 1. This change in optical properties may be achieved by a chemical or physical process, for example by a chemical reaction of a salt on the inner side 6 of the closure 4.
The change in the optical properties includes a change in the color of the closure part 4 when the moisture level exceeds a limit value.
The auditing is carried out automatically in the context of the production and inspection of motor vehicle components to ensure consistent quality. Here, the sensing of the optical properties of the enclosure 4 may be assisted by the camera 7. To simplify the process of the camera 7 finding the enclosure 4, the enclosure 4 is retroreflective and UV-active. In order for the camera 7 to find the enclosure 4, the light emitting means 8 illuminate the enclosure 4 with light 9. If the enclosure 4 is retroreflective of the incident light 9, the light 9 is reflected and detected by the camera 7.
It is conceivable that the degree of retroreflectivity varies depending on the degree of wetness. Thus, if the degree of wetness exceeds a limit value, the enclosure 4 may thus become retroreflective. However, if the degree of wetness is below a limit value, the enclosure 4 may also be retroreflective and lose its retroreflectivity if the degree of wetness exceeds the limit value. However, it is also conceivable for the closure 4 to be retroreflective for a first wavelength when the degree of wetness is below a limit value, and for the closure 4 to be retroreflective for a second wavelength, which is different from the first wavelength, when the degree of wetness is above the limit value.
In order for the camera 7 to find the enclosure 4, the enclosure 4 may also be illuminated by means of light 9 in the UV range. If the enclosure 4 is UV active, light 9 is emitted by the enclosure 4 and detected by the camera 7.
It is conceivable that the degree of UV activity varies depending on the degree of wetness. Thus, if the moisture level exceeds a limit value, the closure 4 may thereby become UV-active. However, if the degree of wetness is below the limit value, the closure 4 may also be UV-active and lose its UV-activity if the degree of wetness exceeds the limit value. However, it is also conceivable that the closure 4 is UV-active for a first wavelength of the incident light 9 when the degree of wetness is below a limit value, and that the closure 4 is UV-active for a second wavelength of the incident light 9, which is different from the first wavelength, when the degree of wetness is above the limit value. It is also conceivable that, when the degree of wetness is below a limit value, the closing part 4 emits light 9 of a first wavelength upon incidence of UV light, and, when the degree of wetness is above the limit value, the closing part 4 emits light 9 of a second wavelength, different from the first wavelength, upon incidence of UV light.
Fig. 2 schematically illustrates a motor vehicle 100 according to an exemplary embodiment of the present invention. The motor vehicle 100 has a battery case 1 according to an exemplary embodiment of the present invention.
