AI Technical Summary
Technical Problem
The flange of the existing battery box is prone to local crushing or deformation around the connection hole, which affects the reliability and sealing performance of the battery device.
Method used
Reinforcing ribs are installed between the flanges of the battery box to enhance the rigidity of the connection holes. The thickness and rigidity of the flanges are increased by the reinforcing ribs, reducing the risk of local crushing and deformation.
Benefits of technology
It improves the reliability and sealing performance of the battery pack, extends the service life of the housing, and reduces the risk of stress concentration during locking.

Abstract
The application provides a battery device, an energy storage device, an energy storage system and a charging network. The battery device comprises a battery cell, a first box, a second box and a connecting piece. The first box covers the second box along a first direction and forms a containing cavity together with the second box, and the battery cell is arranged in the containing cavity. The first box comprises a main body part and a flange part connected to the main body part and arranged around the outer periphery of the main body part, and the flange part is connected to the second box. The flange part has a first surface and a second surface arranged at intervals along the first direction, and the second surface faces the second box. The flange part is provided with a connecting hole penetrating through the flange part along the first direction and a reinforcing rib protruding from the first surface. The reinforcing rib comprises a first reinforcing rib surrounding the connecting hole, and the connecting hole penetrates through the first reinforcing rib along the first direction. The connecting piece is arranged in the connecting hole and connects the first box and the second box. The structural strength of the flange part between the connecting holes is increased through the reinforcing rib, so that the reliability of the battery is improved.
