Abstract: A system includes a battery pack module and a control module. The battery pack module is configured to be implemented in a battery pack. The battery pack module includes cells and one or more force sensors configured to generate at least one force signal indicative of force on the cells within the battery pack module. The control module is configured to: receive the at least one force signal; based on the at least one force signal, detect a state of the cells; and based on the detected state of the cells, at least one of i) modify the state of the cells, ii) generate an alert message, and iii) perform a mitigation operation to address a detected abnormality of the cells.
