Arc extinguishing contact geometry: BYDRecent Research Landscape

High-voltage arcing during emergency disconnects causes catastrophic fire risks in electric powertrains. These innovations utilize rapid chemical expansion to physically sever connections and extinguish arcs instantly.

What technical problems is BYD addressing in Arc extinguishing contact geometry?

Thermal runaway propagation

(32)evidences

Uncontrolled heat transfer between battery cells leads to catastrophic system failure. Preventing this ensures operational safety in high-power vehicle applications.

High voltage circuit interruption

(16)evidences

Electrical discharge during circuit interruption causes contact erosion and thermal damage. Preventing sustained arcs ensures safe isolation in high-power vehicle battery systems.

Excessive parasitic power consumption

(15)evidences

High standby energy loss and inefficient power routing in integrated battery modules. Reducing these losses extends operational range and prevents unintended battery depletion.
