Abstract
According to one embodiment of the present disclosure, a method for detecting an abnormality in a storage battery includes: calculating, based on process data obtained during a manufacturing process, an initial restraining deformation amount of a target prismatic cell in a stack of prismatic cells; calculating, based on the initial restraining deformation amount and usage history data, a deformation amount of the bottom surface of the case of the target prismatic cell; and outputting a first alert in response to the deformation amount of the bottom surface of the case exceeding a predetermined first threshold.
