AI Technical Summary
To meet the requirements of collision and compression conditions, existing power battery boxes adopt multiple crossbeams and high-strength box structures, which leads to problems such as excessive box weight and reduced battery energy density.
The support beam assembly consists of a front crossbeam, a rear crossbeam, and longitudinal beams. Combined with energy-absorbing components and mounting components within the buffer space, the frame structure is optimized to achieve lightweighting while meeting collision requirements.
While ensuring the strength of the battery box, the design of the support beam assembly and energy-absorbing components has achieved lightweighting of the battery box and improved energy density, thus meeting the collision requirements.
