Thermal management modeling and simulation have become critical to electric vehicle (EV) development. Modelica is well-suited for this domain thanks to its multi-disciplinary, acausal modeling capabilities, which naturally capture the physical behavior of batteries, electric motors, power electronics, and their associated cooling systems.
The ThermofluidStream (TFS)​ library, originally developed at DLR, introduces a novel modeling paradigm in Modelica that enables efficient simulation of large-scale thermal-fluid network models. YSLAB, developed by Nanjing Yuansi SimTek, is a browser-based Modelica simulation environment that lowers the barrier to entry for system-level modeling and interactive exploration.
This tutorial is structured in two parts. We begin with an introduction to thermodynamics modeling at the component level using YSLAB. Participants will then engage in a hands-on session to build an EV thermal management system model using the TFS library, from component instantiation to system assembly and simulation.
