Abstract
AURORA‑GRID v2.1 is a structural battery pack architecture that integrates energy storage into the vehicle chassis using gyroid lattices, micro‑fluidic cooling, and self‑sensing skins. v2.0 introduced gyroid cores, graded stiffness, and Arachne smart skin. v2.1 adds:
-
Gradient‑Foam Shock Absorption Layer: printed foam between gyroid and outer skin for crash energy absorption.
-
Micro‑Channel Phase‑Change Cooling: phase‑change coolant in gyroid micro‑channels for zero‑pump thermal control.
-
Self‑Healing Polymer Shell: outer shell that repairs micro‑cracks when heated.
-
Embedded Wireless Power Bus: conductive traces printed inside gyroid lattice to reduce wiring harness mass.
Projected performance if validated:
-
Weight: ~35–40% lower pack structure weight vs conventional packs.
-
Safety/thermal: ~25–35% better stability and crash protection.
-
Range: +10–15% vehicle range due to weight reduction.
-
Lifecycle: +20–25% longer due to hotspot elimination and self‑healing shell.
Core objective
-
Integrate battery pack into vehicle structure without compromising safety.
-
Reduce pack weight while improving cooling and crash performance.
-
Provide a buildable structural battery prototype for OEMs and labs.
