Abstract: With the global demand for reducing greenhouse gas emissions and promoting energy transformation growing increasingly urgent, the importance of electric vehicle (EV) as clean energy transportation tools is becoming more prominent. The air conditioning system and battery thermal management of electric vehicles are key technical areas that affect the vehicle's performance and endurance capabilities. This paper delves into the collaborative design strategies of electric vehicle air conditioning systems and battery thermal management, aiming to optimize energy utilization efficiency and thermal management performance through the construction of an integrated model. The research employs methods of mathematical modeling, simulation analysis, and experimental validation to comprehensively evaluate the system's performance under different operating conditions and proposes effective methods to improve the existing system design. The results show that the collaborative design strategy can not only significantly improve energy utilization efficiency and reduce energy consumption but also enhance the reliability of the system, ultimately enhancing the user's driving experience. The study also provides a new perspective for the sustainable development of electric vehicles, emphasizing the importance of considering environmental impact and energy efficiency in the design process, and lays a solid foundation for the further development of the electric vehicle industry
