Abstract

A detection device detects a mechanical deformation of a high-voltage accumulator of a motor vehicle, and includes: a sensor element, which senses an electrical measurement variable, wherein the sensor element is substantially flat and is attached at least partially to a first component of the high-voltage accumulator; and an evaluation device for analyzing the electrical measurement variable between the sensor element and a second component of the high-voltage accumulator and for outputting a corresponding warning on the basis of the electrical measurement variable, wherein at least one region of the surface of the second component is electrically conductive.
