Provided are a secondary battery and a secondary battery module that can decrease energy of a power generating element of the secondary battery without fail even if, for example, impact of a collision damages a controller controlling charge/discharge of a secondary battery cell or disconnects a wiring connecting the controller and the secondary battery cell. The secondary battery includes a secondary battery cell and a cell controller controlling charge/discharge of the secondary battery cell. The cell controller causes discharge of the secondary battery cell when a collision or a collision probability of a movable object mounting the secondary battery is detected. |
