Özet

Today, increasing air pollution problem, climate change, rapid depletion of oil reserves and their being expensive cause an increase in environmentally friendly, efficient and sustainable work in the transportation sector. For this reason, efforts are being made to expand the use of electric and hybrid vehicles in the transportation sector. In this study, the efficiency and 〖CO〗_2 emission effects provided by the electric motor types used compared to other vehicle engines are estimated by examining the electric and hybrid vehicles sold in our country as well as the historical development, structure and working principle of electric and hybrid vehicles. Preferred engines in electric and hybrid vehicles are compared in terms of efficiency, cost, power density and reliability. Brushless DC motors are determined to be better in terms of efficiency and performance, but costlier. Electric vehicles with permanent magnet synchronous motors are considered to be optimum in terms of efficiency and cost. 〖CO〗_2 emission values of engine types used in vehicles using internal combustion engines electric and hybrid vehicles are compared using basic statistical estimation methods. As a result of the comparison, it is expected that the 〖CO〗_2 emission rate will decrease by 2% or more in the future.
