Abstract

Provided are an end cover assembly, a battery cell, a battery module, and an energy storage device. The end cover assembly includes a cover plate, an explosion-proof valve, a first electrode terminal, and a second electrode terminal. The cover plate has a first protrusion, at least one second protrusion, and at least one third protrusion. The first protrusion has a mounting hole, and the at least one second protrusion and the at least one third protrusion are arranged at two opposite sides of the first protrusion in a length direction of the cover plate, respectively. The explosion-proof valve is mounted in the mounting hole. The first electrode terminal and the second electrode terminal are arranged on the cover plate and spaced apart from each other.
