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.

Abstract: Systems and methods for scanning a battery cell to identify internal faults are disclosed. In certain embodiments, a method for scanning a battery cell for faults may comprise generating an input signal across first and second charge plates disposed on each side of the battery cell. An open circuit voltage of the battery cell generated in response to the input signal may be measured. The measured open circuit voltage may be compared with a reference signal associated with a reference battery cell having no faults. Based on the comparison, a fault and/or a possible fault within the battery cell being scanned may be identified.
