Outline
To address the issues of high modification cost and long development cycles associated with control strategy changes in the thermal management system of battery electric vehicle air conditioning, a collaborative modeling and coupled simulation study of physical mechanism models and control strategies is conducted based on the Modelica language. A high-fidelity white-box physical model is constructed, which covered key components: vehicle air conditioning, passenger cabin, and control strategies. Through a unified Modelica simulation architecture, a fully coupled closed-loop simulation is achieved, integrating thermal, fluid, and control domains. The model is validated using real vehicle test data under a winter heating and dehumidification condition. Results show that in the independent simulation, steady-state temperature errors of the physical system are within ±2 ℃. The responses of valve opening and compressor speed agreed with measured data. In the coupled simulation, the steady-state deviation of compressor speed is below 2%, and the discharge pressure deviation is less than 6%. The steady-state error of pipeline temperature is within 2 ℃. The transient response trend agreed well with the real vehicle data.
