Thermoelectric(TE) materials are one of the latest technologies,which have been used to produce electrical energy from thermal loss. Thermoelectrical technologies have been applied in different industrial utilities such as electronic devices, means of transportation, etc. capability of TE in producing electrical energy from thermal loss is significant like generate electricity from wasted heat in automobiles, industry. Home appliance and most device that produce heat and waste thermal energy. One of the most important application in the vehicle that have different locations in itself that produce heat during driving and can be used as sources of electrical energy. Thus, in this paper heat sources in vehicle are distinguished by measurments.
