Hybrid Vehicles: An Analysis of Efficiency and Environmental Impact

Abstract

This study examines the advantages and disadvantages of hybrid vehicles, focusing on their capacity to mitigate harmful emissions and improve fuel efficiency. It discusses the operating principles of internal combustion engines, electric motors, inverters, and batteries used in hybrid vehicles, illustrating their key roles in improving environmental sustainability. The research analyses three power device interconnection schemes: series, mixed, and parallel, exemplified by Chevrolet Volt and Honda models respectively. The results indicate that despite high upfront costs, hybrid vehicles significantly reduce harmful emissions and fuel consumption, particularly in urban driving conditions. Furthermore, their positive environmental impact and fuel economy potentially position hybrid vehicles as future market dominants. The study highlights the importance of hybrid vehicles in mitigating climate change and calls for continued advancements and global investment in this promising technology.Highlights:
