The project is to design a waste heat recovery system in an electric vehicle by using thermoelectric generator. Range of electric vehicles is low because the electric vehicle not uses its, whole generated power during driving some energy is waste in heat form from the electric motor, battery pack, etc. so to utilize this waste heat energy Thermo-electric generator (TEG) is used over the battery pack to increase the power output. The project aims in designing ofboth the geometries and comparing them on the basis of advantages provided by them. The project provides the TEG geometries that can be employed in vehicles according to their operating conditions. The employment of these geometries yields good results for the vehicle. The purpose of the project is to design the TEG geometries that are specified earlier for a vehicle, designing the required parts, conducting the study over the electric vehicle parts, manufacturing of the parts, assembling TEG on the battery pack and then compare with the actual power generated values. The project is being finalized by following various steps. The project initialized by finalizing the dimensions of the battery pack of an electric vehicle in which the TEG geometry is to be installed. Then we came up with the heat generated by a battery used in electric vehicle (li-ion, nickel hydride, lead acid batteries). Using these values and considerations we employed the TEG (thermo-electric generator) over the battery pack of an electric vehicle. The Thermo-electric generator that will be installed in the vehicle need to be designed so that it will be in accordance with the vehicle and to increase the power output of the vehicle. The calculations for power generated by a TEG or efficiency are done doing manual calculation with the help of formulas. Things we learned in this project are the TEG how it works the battery thermal management system and how a lithium- ion battery work to produce energy to run the vehicle. It should with stand harsh working conditions of the vehicle. The conclusion for the project is to increase the range of the electric vehicle by decreasing the load falling on the battery pack of the vehicle. Load considers the energy used to run the auxiliaries of the vehicle so the energy generated by the TEG is sufficient to run the auxiliaries and in this way the range of the electric vehicle increases. Then comparing both the geometries and specifying where the geometries if installed give good performance of the vehicle.
