Abstract: Systems and methods for monitoring a state of a battery system based on information related to a measured pressure within the battery system are presented. In certain embodiments, the disclosed systems and methods may utilize a pressure-sensitive smart foam material in connection with measuring a pressure within the battery system. Based on the measured pressure information, a variety of information relating to the battery system may be determined. For example, information relating to a state of a battery system, certain events occurring within the battery system, and/or battery lifecycle information may be determined based on the measured pressure information.
