METHOD FOR DETECTING AND EVALUATING A MECHANICAL IMPACT ON A BATTERY PACK IN AN AT LEAST PARTIALLY ELECTRIC VEHICLE

Abstract: the present disclosure refers to a method for detecting and evaluating a mechanical impact on a battery pack in an at least partially electric vehicle, wherein the battery pack is disposed on an underbody of the vehicle. the method includes a step of detecting first condition data determining an underbody impact using a first sensor. further, the underbody impact is determined based on the detected first condition data. afterwards, a degree of severity, comprising a plurality of levels, of the underbody impact is determined based on second condition data characterizing a severity of the underbody impact detected using a second sensor. furthermore, an output is determined based on the determined degree of severity. the invention further relates to a battery system including a battery pack, wherein the battery pack is disposable on an underbody of an at least partially electric vehicle, comprising at least one battery cell, a first sensor and a second sensor and/or a communication interface for detecting and/or obtaining first and second condition data, and a control unit being configured for performing the disclosed method, and to an electric vehicle comprising the battery system according to the invention.
