Problems solved by technology

However, it is disadvantageous if the high-voltage battery and the battery housing are to be tested for inspection, for example during a quality control audit, during a stop in a workshop or also while the motor vehicle is in operation
Especially due to the encapsulation of the high-voltage battery, the humidity inside the battery housing can only be measured cumbersomely

Embodiment Construction

[0053] figure 1 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 are shown schematically. The battery case 1 is a motor vehicle (see figure 2 ) of the battery case 1. Arranged in the battery housing 1 is a high-voltage battery 2 , which is used, for example, to supply an electric machine with voltage or current for driving the motor vehicle.

[0054] The opening 3 of the battery housing 1 is closed by means of a closure 4 (here by means of an adhesive). The closing part 4 is transparent at least for each wavelength range in the visible range, so that the inner space 5 of the battery case 1 can be inspected through the closing part 4 . In order to ensure better mechanical protection of the high-voltage battery 1 , the closure 4 is designed to be stable and tear- and puncture-resistant.

[0055] In order to be able to determine the degree of humidity in the interior 5 of...

Abstract

The invention relates to a battery housing (1) for accommodating a high-voltage battery (2), in particular a high-voltage battery (2) of a motor vehicle (100), the battery housing (1) having an opening (3), the opening (3) being closed by a closure (4), wherein the closure (4) is configured such that an optical property of the closure (4) varies depending on a degree of humidity on an inner side (6) of the closure (4) facing an inner space (5) of the battery housing (1). The invention further relates to a motor vehicle (100) and to a method for checking a high-voltage battery (2) arranged in a battery housing (1).

Description

technical field [0001] The invention relates to a battery housing for accommodating a high-voltage battery, in particular a high-voltage battery of a motor vehicle, a motor vehicle and a method for checking a high-voltage battery arranged in a battery housing. Background technique [0002] High-voltage batteries, especially for motor vehicles, are typically arranged in battery housings. During operation of a motor vehicle, strong mechanical loads (eg constant acceleration and braking, oscillations, 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. [0003] Furthermore, it is very important that the humidity in the battery case is below a critical value. In the event of excessive humidity, the high voltage battery may be damaged (eg due to a short circuit). [0004] The opening of the battery case is closed to protect the high-voltage battery. ...
