Modular battery pack interconnects: BYDRecent Research Landscape

High electrical resistance at cell-to-pack interfaces causes thermal runaway risks and energy loss. Engineering the physical connection structure ensures stable current distribution and mechanical integrity under vibration.

What technical problems is BYD addressing in Modular battery pack interconnects?

Structural integrity under mechanical stress

(85)evidences

Inconsistent positioning during high-volume cell integration leads to poor electrical contact and structural instability. Precise alignment ensures reliable interconnect integrity and reduces manufacturing defects.

Mechanical interconnect instability

(44)evidences

Structural failure or loosening of modular connections during vehicle operation. Secure fastening prevents electrical discontinuity and pack deformation.

Inadequate internal component protection

(42)evidences

Environmental ingress and mechanical stress damage sensitive battery cells and electronics. Robust containment prevents premature failure and ensures operational safety in portable equipment.

Inadequate energy density scalability

(40)evidences

Limited volumetric energy density and packaging complexity in vehicle chassis. Resolving these constraints increases total energy capacity within fixed automotive footprints.

Structural housing integrity failure

(27)evidences

Mechanical vulnerability and environmental exposure of individual cells within high-density assemblies. Robust containment prevents premature failure due to external stressors or internal displacement.
