Method and rating system for evaluating a further usability of a high-voltage memory of a motor vehicle after a critical event

摘要

The invention relates to a method for evaluating a further usability of a high-voltage accumulator (2) of a motor vehicle (3) according to an event critical for the high-voltage accumulator (2), acceleration sensor data detected by an acceleration sensor device (4) of the motor vehicle (3) being received in the method and the further usability of the high-voltage memory (2) is evaluated on the basis of the acceleration sensor data. In addition, at least one time-dependent partial acceleration profile (12) corresponding to the critical event is extracted based on the at least one time-dependent partial acceleration profile (12) and based on at least one predetermined reference acceleration profile a degree of damage of the high-voltage memory (2) is determined and the further usability of the high-voltage memory (2) is evaluated based on the degree of damage. The invention also relates to a rating system (1).
