Optimization of Cooling Circuit for Electric Vehicle

Thermal management is paramount in electric vehicles (EVs) to ensure optimal performance, battery longevity, and overall safety. This paper presents a novel approach to improving the efficiency of cooling systems in automotive passenger vehicles, focusing specifically on battery circuits and e-motor cooling. Current systems employ separate pumps, degassing tanks, valves, and numerous mechanical components, resulting in complex layouts and increased assembly efforts.The primary challenge with the existing setup lies in its complexity and the associated drawbacks, including heat energy loss, increased weight, and space constraints. Moreover, the traditional approach necessitates a significant number of components, leading to higher system costs and maintenance requirements.To address these challenges, this paper proposes an integrated cooling system where the pump, degassing tank, and valves are consolidated into a single housing. This streamlined design reduces the component count by approximately 30%, significantly minimizing the number of hoses and actuators. As a result, the integrated system offers several advantages, including improved efficiency, reduced weight, and space savings of approximately 30%.The proposed approach will be further validated through experiments, evaluating the performance of the integrated cooling system under various operating conditions, this research aims to demonstrate its effectiveness in enhancing thermal management in automotive applications.
