The frequency of worldwide disastrous weather is intensified by the global climate warming. The disastrous weather such as freezing rain and snow is extremely disadvantageous to the vehicle performance and safety. This paper summarizes and classifies the current snowmelt deicing methods at home and abroad; emphatically proposes the trend of future active development for snowmelt technology and introduces the snowmelt deicing technology of electric heat tracing, which is the competed developing new technology in the countries of cold region acting as one of the snow removal measures in winter cold regions. The electro-thermal snowmelt deicing technology involves relatively wider field of knowledge, whose research and development are also increasingly connected with the development of other technologies. This paper reviews the development history of electro-thermal snowmelt deicing technology and summarizes the main research condition of domestic electro-thermal snowmelt deicing technology in the last few years, furthermore looks forward the development and application prospect of electro-thermal snowmelt deicing technology by brief description of the current research situation.
