Hybrid electric vehicles (HEVs) hold significant importance in the automotive industry owing to their superior fuel efficiency, lower operating costs, reduced emissions, and enhanced performance. This article proposes a novel battery cooling system for HEVs designed to minimize the electrical power required for battery thermal management. The proposed control strategy is based on the battery’s real-time temperature. First, the engine architecture of the HEV is outlined. Subsequently, mathematical models of key components—including the internal combustion engine, electric motor, battery, and driver—are developed, and their governing equations are derived. The HEV is then simulated in MATLAB to analyze the impact of vehicle speed on battery temperature and cooling system performance. A comparative study is conducted between the proposed and conventional cooling systems, evaluating battery temperature trends, cooling pump power consumption, and refrigerant power under speed variations based on the FTP-75 driving cycle. The results demonstrate that the proposed controller effectively maintains the battery temperature within the permissible range while reducing cooling power consumption by 30% and eliminating peak refrigerant power demands.
