Abstract

Energy management in modern vehicles is a crucial issue, especially in the case of electric vehicles (EV) or hybrid vehicles (HV), in which different energy sources and loads must be considered for the operation of a vehicle. Air conditioning is an important load that must be thoroughly analysed because it can constitute a considerable percentage of the energy demand. In this paper, a simplified and dynamic thermal model for the cabin of a vehicle is proposed and validated. The developed model can be used for the design and testing of the heating, ventilation, and air conditioning (HVAC) system of a vehicle and for the study of its effects on the performance and fuel consumption of vehicles, such as EVs or HVs. The model is based on theoretical heat transfer, thermal inertia, and radiation treatment equations. The model results obtained from simulations are compared with the cabin air temperature of a vehicle under different conditions. This comparison demonstrates the accuracy between the simulation results and actual results.
