This application provides an output electrode base, a battery module, and an electric vehicle, and relates to the technical field of batteries. The output electrode base provided in this application includes: a base body and a connecting member. A cavity is made in the base body. At least a part of the connecting member is located inside the cavity and fixed to the base body. A plurality of first stop blocks are disposed around an outer peripheral wall of the connecting member, and the plurality of first stop blocks are configured to limit movement of the connecting member. The battery module provided in this application includes: a battery cell; an output electrode base provided in this application; and an output electrode connecting plate, fixed to the output electrode base.

Output electrode base, battery module, and electric vehicle

This application provides a fireproof component, a battery pack, and a device using the battery pack as a power supply. The fireproof component includes a main body and a frame. The frame includes a body portion, an extension portion, and an opening defined by an inner peripheral face of the body portion. The extension portion is located circumferentially outside the body portion and connected to the body portion. The extension portion extends along a third direction that is perpendicular to a plane defined by the frame and protrudes beyond the body portion. The main body covers the opening of the frame and is connected to the body portion. The main body and the frame of the fireproof component are parts independent of each other, and therefore, can be made of different materials and in different molding processes.
