Abstract: A vehicle, comprising a battery pack. The battery pack comprises a battery or a battery module. The battery comprises an explosion-proof valve. The explosion-proof valve comprises an explosion-proof valve body. The explosion-proof valve body has an opening region, and the opening region is provided with an explosion-proof notched groove at the edge thereof. The explosion-proof notched groove comprises a first straight line section, two arc sections and at least one second straight line section. Two ends of the first straight line section are connected to the two arc sections, respectively; at least one of the ends of the second straight line section is connected to the arc section; and the first straight line section is arranged parallel to the second straight line section. In a depth direction of the explosion-proof notched groove, an orthographic projection of the opening region is in an oblong shape. An outer edge of the orthographic projection of the opening region is a predetermined opening boundary, and the area of the orthographic projection of the opening region is S, where S=a×b+π×b 2 /4, S≥80mm 2 , and b≥6mm.

Abstract: The present disclosure provides a battery core assembly (10), a battery (100), a battery pack (200), and a vehicle (300). The battery core assembly (10) includes an encapsulation film (11) and an electrode core assembly (12). The electrode core assembly is arranged in an accommodating cavity (110) defined by the encapsulation film, and the electrode core assembly (12) includes at least one electrode core (121). The electrode core assembly is provided with two electrode lead-out members (122) of opposite polarities for current output. An intermediate ring (13) is further arranged in the accommodating cavity (110) at a side of the electrode core assembly (12) provided with the electrode lead-out member, and provided with an electrode lead-out hole (131) for leading the electrode lead-out member out. Moreover, the present disclosure further provides a battery (100), a battery pack (200), and a vehicle (300) based on the battery core assembly provided in the present disclosure.
