Provides heat insulation, sound insulation, power generation and flexible, transparent and curved glass for EVs. The core products address pain points in electric vehicles, such as that the inside of EVs is too hot in summer and too cold in winter and that the battery keeps losing its charge, resulting in short durability, driver’s anxiety and other problems. There is a vacuum layer between the two glass for heat and sound insulation. The inner surface of one glass is coated with photovoltaic film to convert solar energy into electric energy. The product has completed R & D.
