Fusion42 · 7 October 2026 · Fusion42 review

BYD has filed a patent for an innovative EV battery cooling system where battery modules are fully submerged in a dielectric coolant fluid within a dual-compartment enclosure to prevent electrical risks and fluid leaks.

This Wire brief sits within Fusion42's coverage of Electric Vehicles.
