Description

The invention relates to an arrangement of a storage housing for an electrical energy storage device on the underside of a motor vehicle according to the preamble of claim 1. WO 2024 / 175 538 A1 discloses a protective device for a battery housing arranged in the underfloor area of an electrically powered motor vehicle, with at least one protective element comprising at least one protective plate arranged on the underside of the battery housing and at least one cushioning layer arranged between the protective plate of the protective element and the battery housing, wherein the cushioning layer is made of a flexible material and has at least one chamber filled with a gaseous medium. The object of the invention is to create an arrangement of a storage housing for an electrical energy storage device on the underside of a motor vehicle, so that security against damage to the electrical energy storage device can be particularly increased. This problem is solved according to the invention by arranging a storage housing for an electrical energy storage device on the underside of a motor vehicle with the features of claim 1. Advantageous embodiments of the invention are the subject of the dependent claims and the description. The invention relates to an arrangement of a storage housing for an electrical energy storage device, in particular an arrangement of the electrical energy storage device, on the underside of a motor vehicle. The motor vehicle is, for example, a passenger car. Preferably, the motor vehicle, particularly in its fully manufactured state, has the electrical energy storage device, and in particular the storage housing of the electrical energy storage device. The underside of the motor vehicle is understood to be the underside of the vehicle that points downwards in the vehicle's vertical direction. The fact that the storage housing or the electrical energy storage device is arranged on the underside of the motor vehicle can be understood, in particular, to mean that the storage housing or the electrical energy storage device is located in an underfloor area of the motor vehicle, that is, for example, in the vehicle's vertical direction beneath at least one floor element of the motor vehicle. The electrical energy storage device can therefore also be referred to as an underfloor storage device. The floor element is, for example, part of the motor vehicle's body. For example, the floor element is designed as the main floor of the body. The body is preferably designed as a self-supporting body. Preferably, the floor element at least partially, and in particular predominantly or completely, delimits an interior space of the motor vehicle downwards in the vehicle's vertical direction. The interior space, which can be referred to as the vehicle interior, can in particular be understood to be a passenger compartment or a passenger cell. The motor vehicle is preferably designed as an electrically powered vehicle. This means that the motor vehicle has at least one electric motor by which it can be powered or is powered. In other words, the motor vehicle is designed as a battery-electric vehicle or as a hybrid vehicle. An electrical energy storage device can be understood to be, in particular, a battery or accumulator. Preferably, the electrical energy storage device is designed as a high-voltage component, that is, in particular as a high-voltage storage device. Accordingly, the electrical energy storage device is, for example, designed as a high-voltage battery. Preferably, the electric machine can be supplied with electrical energy, in particular energy stored or chemically bound in the electrical energy storage device, to power the motor vehicle. In other words, the electrical energy storage device is designed as an electrical traction storage device, for example, as a traction battery. The storage housing can also be referred to as a battery housing. Preferably, the storage housing at least partially, and in particular predominantly or completely, encloses at least one receiving space for the electrical energy storage device. At least one storage cell of the electrical energy storage device is preferably arranged or can be arranged within this receiving space, and is specifically designed for storing or chemically binding electrical energy. The storage cell is preferably designed as a battery cell. The storage housing is attached to at least one body component of the motor vehicle, in particular one designed separately from the storage housing, and in particular separately from the electrical energy storage device, by means of at least one holding device designed separately from the storage housing, and in particular separately from the storage housing. For example, at least indirectly or directly. In other words, the storage housing, and thus in particular the electrical energy storage device, is attached to the vehicle body component, especially on the underside, by means of the mounting device.
