SAFETY DEVICE, BATTERY PACK HAVING A SAFETY DEVICE, AND METHOD FOR PRODUCING A SAFETY DEVICE

The invention is based on a protection device (10a-f) for at least one battery cell (12a), with a protection element (14a-f) for interrupting a current flow from the battery cell (12a) in a critical state of the battery cell (12a), with a heating unit (16a-f) which is coupled to the protection element (14a-f), in particular electrically and/or thermally and/or mechanically, and is provided to support triggering of the protection element (14a-f), and with a control unit (18a) for activating the heating unit (16a-f) in the critical state. [0002] It is proposed that the protection device (10a-f) has at least one carrier element (20a-f) for receiving the protection element (14a-f) and at least one heating element (22a-f) of the heating unit (16a-f).
