Improved equivalent circuit coupled 3D thermal cylindrical lithium-ion battery model using a multi-partition heat generation and thermal resistance approach Open
This study introduces an improved equivalent circuit coupled 3D thermal model, the Multi-Partition Heat Generation and Thermal Resistance (MPH-TR) Model, developed for cylindrical Lithium-Ion-Battery (LIB) cells to optimize battery thermal…
Influence of Lithium-Ion-Battery Equivalent Circuit Model Parameter Dependencies and Architectures on the Predicted Heat Generation in Real-Life Drive Cycles Open
This study investigates the influence of the considered Electric Equivalent Circuit Model (ECM) parameter dependencies and architectures on the predicted heat generation rate by using the Bernardi equation. For this purpose, the whole work…
Experimental and Numerical Investigation of the Aerodynamic Ventilation Drag of Heavy-Duty Vehicle Wheels Open
Due to current EU regulations, constant-speed testing on test tracks is used for aerodynamic certification of heavy-duty vehicles (HDV). However, the aerodynamic development of HDVs is performed using wind tunnels and computational fluid d…
Thermal Management System of the UNICARagil Vehicles—A Comprehensive Overview Open
The collaboration project UNICARagil aiming to develop new autonomous battery electric vehicle concepts has progressed and the four vehicle prototypes have been built up. All seven universities and six industrial partners have worked towar…
Aerodynamics of High-Speed Trains with Respect to Ground Simulation Open
Wind tunnel testing is commonly used to assess and optimize the aerodynamic characteristics of high-speed trains. The train model is usually mounted above a static ground plane, but a moving ground is necessary for the correct representati…
Experimental Data for the Validation of Numerical Methods: DrivAer Model Open
As the automotive industry strives to increase the amount of digital engineering in the product development process, cut costs and improve time to market, the need for high quality validation data has become a pressing requirement. While t…
The Influence of Different Unsteady Incident Flow Environments on Drag Measurements in an Open Jet Wind Tunnel Open
Aerodynamic development for road vehicles is usually carried out in a uniform steady-state flow environment, either in the wind tunnel or in Computational Fluid Dynamics (CFD) simulations. However, out on the road, the vehicle experiences …
