Review of research on lightweight battery box of pure electric vehicle

摘要

The lightweight of electric vehicle battery box is one of the effective ways to reduce the overall weight of the battery pack. According to the overview of the current research status of the battery box，the current situation and development trend of battery box material selection（metal，alloy，composite），structure optimization（size optimization，shape optimization，shape optimization，topology optimization，multi-objective optimization），manufacturing technology（stamping，die-casting，extrusion）were discussed.
