Abstract

The invention discloses a drainage valve for a battery box body, a battery, an electric device and a drainage method. The drainage valve comprises a sealing piece and an expansion piece, the sealing piece is arranged on the outer side of the drainage port, the expansion piece is arranged on the side, facing the drainage port, of the sealing piece, and the expansion piece is arranged to expand after absorbing water and extrude the edge of the sealing piece to move in the direction away from the inner side of the drainage port. According to the technical scheme, the drainage valve is connected to the drainage opening of the battery box body and then seals the drainage opening. After water enters the battery box body or the cooling liquid leaks, the water / cooling liquid in the battery box body is in contact with the expansion part, and the expansion part expands and extrudes the sealing part after absorbing water, so that the edge of the sealing part is bent and deformed in the direction far away from the battery box body, and a gap is formed between the outer side of the battery box body and the sealing part; therefore, the water / cooling liquid can be discharged from the gap in time, and the use dangers such as short-circuit fire, explosion and the like of the battery can be reduced.

Description

technical field [0001] The present application relates to the field of batteries, and in particular, to a drain valve for a battery box, a battery, an electrical device and a drain method. Background technique [0002] Energy saving and emission reduction is the key to the sustainable development of the automobile industry. Electric vehicles have become an important part of the sustainable development of the automobile industry due to their advantages of energy saving and environmental protection. For electric vehicles, battery technology is an important factor in its development. [0003] However, the current battery is difficult to discharge after water enters or the cooling liquid in the battery leaks, which causes the battery to be in danger of use. SUMMARY OF THE INVENTION [0004] In view of the above problems, the present application provides a drain valve for a battery box, a battery, an electrical device and a drainage method, which can alleviate the existence an...
