AI Technical Summary

Technical Problem

Batteries are prone to failure when subjected to shock and vibration, causing the connection between the battery cell and the adapter to fail or the adapter to break, affecting the normal operation of the battery.

Method used

A battery cell structure is designed, including a shell, an end cover, an insulating part, a battery cell, a pole and a bottom support plate. The bottom support plate is provided with a first limiting portion to stop and limit the battery cell, prevent vibration, and improve the position stability of the battery cell. The insulating part is supported by the first limiting portion to prevent the adapter from being squeezed, thereby enhancing the connection stability of the conductive circuit.

Benefits of technology

It improves the position stability of the battery cells, prevents adapter breakage and connection failure, ensures the effectiveness of power transmission, and avoids abnormalities such as short circuits in battery cells.

Abstract

The present application discloses a battery cell, including a shell, including an inner cavity and an opening connected to the inner cavity; an end cover, covering the opening; an insulating member, arranged in the inner cavity and connected to the end cover; a battery cell, arranged in the inner cavity, the battery cell, the insulating member and the end cover are arranged in sequence along a first direction; a pole, through which the end cover and the insulating member are sequentially passed, and at least part of the pole is located in the inner cavity; an adapter, arranged in the inner cavity, and respectively connected to the pole and the battery cell; a bottom support plate, arranged in the inner cavity, the bottom support plate including a bottom support portion and a first limiting portion, the bottom support portion is arranged on the side of the battery cell away from the insulating member, the first limiting portion is arranged on the first side of the battery cell, the first side is perpendicular to the second direction; the second direction intersects with the first direction. In summary, the arrangement of the bottom support plate can improve the positional stability of the battery cell, thereby realizing anti-fracture protection for the adapter, and preventing failure of the connection between the battery cell and the adapter, thereby avoiding abnormalities such as short circuits in the battery cell. The present application also discloses an energy storage device and electrical equipment.
