Presentation by Massimiliana Carello, from Beond & Politecnico di Torino.
Nowadays automotive climate control systems are evolving at a rapid pace to meet the overall vehicle requirements. System evaluation is one of the major requests currently faced by the automotive manufacturers and their suppliers. Thermal comfort, convenience and range are equally important user expectations, even if they may represent “opposed” performance for a modern EV, especially in an urban driving cycle.
In this framework, to achieve the expected targets and limiting the time-to-market and costs, a complete vehicle thermal model is to be developed to evaluate the cockpit thermal request for occupants' comfort at different ambient temperatures as well as solar radiation. Furthermore, the battery thermal management is to be investigated, to avoid cells damages and deterioration. The aim of this technical presentation is to highlight the integration capabilities of a lumped parameters model (1D) developed with Altair Activate for fast simulations and a CFD model (3D) of the battery liquid cooling system developed in AcuSolve. The Models realized are validated using experimental data.
