The thermo electric generators are utilized to extract exhaust heat to generate the electricity which is used to charge the battery of vehicle and used for various electronics applications. The heat pipes and thermo electric generation system is used in combination to produce more exhaust heat power generation system. Increase in the sales of passenger vehicle across the world, in turn passenger vehicle segment of vehicle type is subjected to the highest growth rate during the forecast period. The diesel engine vehicle is banned by several nations and higher is the sales of gasoline engine vehicle because of light weight and less fuel consumption. Thus, the gasoline segment of propulsion is anticipated to hold the major shares of the global exhaust heat power generation system market over the forecast period.
