Original Abstract Submitted
A battery system includes a plurality of cells, a hermetically sealed pack case, a first abnormality detection sensor, a second abnormality detection sensor, and a controller. The plurality of cells each includes a hermetically sealed cell case. The cell case includes a first pressure valve configured to irreversibly rupture by a predetermined activation pressure. The controller is configured to execute an abnormality determination process of determining that an abnormality occurs in at least one of the plurality of cells if the pressure value detected by the first abnormality detection sensor is higher than a predetermined threshold value and the detection value detected by the second abnormality detection sensor is higher than a predetermined threshold value.
