Abstract
The global automotive industry is moving towards sustainable mobility through vehicle electrification & autonomous connected vehicles. OEMs face many challenges in this relatively new field, such as battery design and charging infrastructure, and even long-standing design requirements such as thermal management, cabin comfort and vehicle noise are re-defined by electrification.
The lack of waste heat from an internal combustion engine (ICE) means that electric vehicles need to consume additional power for heating. It is important to strike a balance between range and comfort to design an energy efficient electric vehicle.
Electric vehicles are also quieter and non-engine noise sources are now more noticeable. HVAC noise in particular can impact the passenger experience negatively, as it can contain tonal components created by resonances and blower/stator interactions as well as broadband jet noise in the frequency range of human speech that can reduce audibility.
Simulation provides an edge in the competitive EV industry. An advanced virtual twin can help to size the HVAC system, and predict battery life, vehicle range, thermal comfort and noise during early design stages. In this Tech Talk we will present a vehicle HVAC simulation workflow that permits big improvements in turnaround time and simulation cost.
