Extruded battery tray side rails: BYDRecent Research Landscape

Mechanical failure during side-impact collisions risks catastrophic thermal runaway in battery enclosures. These innovations engineer the cross-sectional geometry and assembly of side rails to maximize energy absorption and structural integrity.

What technical problems is BYD addressing in Extruded battery tray side rails?

Insufficient structural crashworthiness

(111)evidences

Inadequate protection of battery cells during side-impact collisions. Enhancing energy absorption prevents catastrophic pack deformation and thermal runaway.

Insufficient structural impact resistance

(16)evidences

Inadequate protection of battery cells during side-impact collisions leads to catastrophic pack failure. Enhancing the energy absorption of the tray perimeter prevents mechanical intrusion and thermal runaway.
