Integrated chassis battery housing: BYDRecent Research Landscape

Standard battery enclosures increase vehicle weight and assembly complexity, which is mitigated by structural integration into the vehicle chassis. This approach reduces component count while maintaining mechanical protection and thermal isolation.

What technical problems is BYD addressing in Integrated chassis battery housing?

Uncontrolled thermal runaway propagation

(59)evidences

Mechanical intrusion and collision forces threaten the integrity of internal electrochemical cells. Preventing structural breach ensures passenger safety and prevents thermal runaway in power-consuming devices.

Insufficient volumetric energy density

(27)evidences

Traditional battery packaging creates redundant weight and wasted internal volume. Integrating the housing into the chassis addresses the limitation of low volumetric energy density and poor structural efficiency.

Insufficient vehicle structural integration

(26)evidences

Conventional battery packs act as parasitic mass rather than load-bearing components. Integrating the housing into the chassis addresses the limitation of redundant structural weight and poor volumetric efficiency.
