Composite battery guard plate: BYDRecent Research Landscape

Road debris and bottom-impact events cause catastrophic battery punctures and thermal runaway. These structures utilize layered composite geometries to absorb kinetic energy and shield cells from mechanical deformation.

What technical problems is BYD addressing in Composite battery guard plate?

External impact structural damage

(39)evidences

Battery cells are vulnerable to structural failure from crushing or penetration. Preventing physical deformation ensures the integrity of the power system and prevents thermal runaway.

Underbody impact structural failure

(23)evidences

External mechanical intrusion and debris strikes threaten the integrity of battery enclosures. Preventing structural breach ensures the safety of the energy storage system during road hazards.

Undetected battery underbody damage

(17)evidences

Hidden structural damage to protective plates often goes unnoticed until thermal runaway occurs. Early identification of mechanical compromise prevents catastrophic battery failure.
