An apparatus includes a battery arrangement and a protective arrangement. The protective arrangement includes a first layer, a second layer, a third layer disposed between the first layer and the second layer, and acceleration sensors. The third layer has a layer volume that can be reduced under the effect of pressure. The acceleration sensors include at least one first acceleration sensor and at least one second acceleration sensor. The least one first acceleration sensor is disposed in contact with the first layer and is configured to generate and output a first sensor signal as a function of the acceleration and wherein the at least one second acceleration sensor is disposed in contact with the second layer and is configured to generate and output a second sensor signal (SIG) as a function of the acceleration in order to enable detection of damage to the protective arrangement.

Protective arrangement for vehicle battery

A battery arrangement for an electric vehicle including a battery housing and a plurality of battery cells. The battery cells are arranged in the battery housing. A protective plate is arranged on a side of the battery and faces toward a roadway. A deformation detection device includes at least one deformation sensor arranged at the protective plate. The protective plate is constructed of multiple layers and includes at least one first layer and one second layer separate from the first layer. The deformation detection device includes a first deformation sensor and a second deformation sensor. The first deformation sensor is arranged at the first layer of the multi-layer protective plate and the second deformation sensor is arranged at the second layer of the multi-layer protective plate.

Battery arrangement for an electric vehicle

A motor vehicle, in particular an at least partly electrically driven motor vehicle, has a battery device with at least one battery cell. The battery device is arranged in a floor region of the motor vehicle and has a protective device for protecting the battery device from mechanical action. The protective device has a protective plate, which is arranged in such a way that it covers the battery device at least in some regions, so that any mechanical actions are absorbed by the protective plate. The protective device also has an acoustic monitoring device, which monitors the protective plate acoustically and with which a signal can be output when a noise characteristic of a mechanical impairment of the protective plate is registered. Also disclosed is a method for monitoring the protective device.

Motor vehicle and a monitoring method

A battery arrangement for a motor vehicle, with a battery which has a battery housing and a plurality of battery cells. The battery cells are arranged in the battery housing. A protective plate is arranged at least on one side of the battery. A damage detection apparatus has a damage indicator. The damage indicator is arranged on the protective plate. The damage indicator is embedded into the protective plate.
