Traditional HVAC-based defrost warms the cabin before it clears the windshield. That delays visibility, adds energy demand and puts winter range under pressure when drivers need it most.
— cabin heat is redirected away from passengers and glass
— range and defrost efficiency drop in cold weather
— more energy gets spent before the vehicle is ready
— longer warm-up means more energy use and more waiting
Betterfrost combines direct glass heating, pulsed power control, and smart activation to clear frost efficiently while reducing HVAC load.
Energy is applied at the windshield surface, reaching the thin interfacial layer where frost bonds to the glass.
Pulsed power limits heat penetration, helping release ice efficiently instead of wasting energy on bulk heating.
Detection and control logic allow the system to operate only when needed and stop when the surface is clear.
Betterfrost applies pulsed heating through conductive low-e glass, directing energy to the thin interfacial ice layer where frost bonds to the surface. Instead of heating the cabin first, it clears the glass directly and reduces HVAC defrost load.
