The following Application Highlight addresses the measurement of materials for thermal simulation modelling using the Modified Transient Plane Source (MTPS) and Transient Plane Source (TPS) methods.
Thermal simulation is commonly used in electric vehicle (EV) development to understand and predict how heat behaves within the vehicle's components and systems. It involves creating a virtual model of the EV system and using specialized software to simulate heat transfer, temperature distribution, and cooling effects. Thermal simulation helps engineers optimize the design of EVs by evaluating and improving battery thermal management, HVAC systems, and motor & power electronics cooling. One important factor in thermal simulation is thermal conductivity, which refers to how well a material can conduct heat. Understanding the thermal conductivity of different components helps engineers determine efficient cooling strategies and select appropriate materials to enhance heat dissipation and prevent overheating, ensuring optimal performance and safety of electric vehicles. ThermoAnalytics, Inc. (TAI) is a leading developer of thermal, fluid flow, and infrared modelling software. Their flagship software TAITherm is a thermal simulation software, that produces transient test results within hours, solving for all modes of heat transfer. In collaboration with C-Therm, TAITherm and Trident were used in the testing for two specific case studies involving the thermal mapping of electric vehicles. Specifically, the mapping of electric motors and a NREL Thermal Runaway Model.
