1. An apparatus comprising:
a battery arrangement; and
a protective arrangement including acceleration sensors, a first layer, a second layer, and a third layer disposed between the first layer and the second layer,
wherein the third layer has a layer volume that is configured to be reduced under an effect of pressure,
wherein the acceleration sensors include at least one first acceleration sensor and at least one second acceleration sensor,
wherein the at 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 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 as a function of acceleration in order to enable detection of damage to the protective arrangement.
