AI Technical Summary
Traditional steel battery casings are heavy, take up a lot of space, and have high production costs. Aluminum or steel-aluminum hybrid battery casings increase production costs and make it difficult to achieve lightweighting and carbon emission reduction while ensuring safety performance.
The rectangular frame and longitudinal beams are formed by roll forming of high-strength steel and are connected by welding and bolting to form the battery shell structure. Drainage holes are designed during the electrophoretic coating process to optimize material use and reduce electrophoretic liquid residue.
While ensuring vehicle safety performance, production costs were reduced and carbon emissions were decreased, achieving a lightweight design for the battery casing.
