1. A detection device for detecting a mechanical deformation of a high-voltage accumulator of a motor vehicle, comprising:
a sensor element applied to a first component of the high-voltage accumulator, wherein the sensor element is configured to detect a measured electrical quantity between the sensor element and a second component of the high-voltage accumulator, and wherein at least a region of a surface of the second component is electrically conductive; and
an evaluation device configured to:
detect the mechanical deformation from the measured electrical quantity, and
output a warning message in response to detecting the mechanical deformation.
