Abstract:
1. A battery system, comprising: a connection terminal configured to function as one electrode of the battery system; a battery case made of a conductive material, forming an internal space, and configured to function as an other electrode of the battery system; a battery module located in the battery case and electrically connected to the connection terminal; a heating element structure located in the battery case and generating heat by an external impact; a pin structure for concentrating and transferring the external impact to a predetermined region of the heating element structure, wherein the external impact is applied to the battery case and then transferred to the pin structure; and a thermal switch preventing the battery module from being electrically connected to the battery case, thereby enabling the battery system to be reserved, wherein the thermal switch is melted by the heat generated by the heating element structure, to electrically connect the battery module and the battery case, which causes the battery case to function as the other electrode of the battery system.
