Abstract
Hybrid Electric Vehicles (HEVs) are rapidly gaining traction as a sustainable alternative to
conventional vehicles, thanks to their ability to reduce fuel consumption and lower emissions. However, HEVs
generate a significant amount of heat during operation, particularly in the powertrain and battery systems, which
can reduce efficiency and lead to component degradation. This paper proposes an Integrated Heat Recovery
Cooling Mechanism (IHR-CM) for HEVs that combines conventional cooling systems with advanced heat
recovery techniques. The mechanism uses thermoelectric generators (TEGs) to capture waste heat from the
engine, battery, and power electronics, converting it into usable energy for the vehicle’s auxiliary systems or
battery recharging. Additionally, an AI-driven thermal management system is integrated into the IHR-CM to
optimize cooling processes based on real-time driving conditions. This proactive cooling management reduces
energy consumption and improves the overall thermal efficiency of HEVs. The proposed system is designed to
extend the lifespan of critical components, improve vehicle efficiency, and reduce the overall energy demand on
the battery. Through a comprehensive analysis of existing cooling systems and heat recovery technologies, this
paper outlines how the IHR-CM can address the challenges associated with thermal management in HEVs,
leading to enhanced performance and sustainability
