Structural battery frame integration: BYDRecent Research Landscape

Standard battery enclosures add parasitic weight and reduce volumetric energy density. Engineering the vehicle frame to serve as the primary containment structure maximizes load-bearing efficiency while increasing range.

What technical problems is BYD addressing in Structural battery frame integration?

Chassis structural weight penalty

(30)evidences

Inadequate integration between battery enclosures and vehicle chassis leads to inefficient force distribution. Resolving this improves crashworthiness and reduces parasitic weight.

Inadequate structural load distribution

(29)evidences

Standard vehicle frames treat structural support and energy storage as separate systems, leading to redundant mass and wasted spatial capacity. Integrating these functions addresses the physical footprint limitations of traditional chassis designs.

Chassis structural weight redundancy

(20)evidences

Traditional vehicle designs treat battery packs as parasitic mass rather than load-bearing elements. Eliminating redundant structural members reduces vehicle mass and increases energy density.
