Stricter demands on emission norms, fuel economy and performance require internal combustion engines to be optimized with respect to their frictional losses and wear. Different investigations show that the piston group, consisting of piston skirt and rings, cylinder liner and conrod bearings, contributes a major part to the overall frictional losses. Although the ICE exists […]
Reducing the emission of the conventional vehicles by means of electrification of the powertrain brings new trends and new challenges for automotive engineers, especially in the field of thermal management and thermal component security. Thermal management systems for xEVs show a high degree of topological complexity, integration of new functions, more interaction between the different […]
Learn how to use a model to evaluate battery pack safety during thermal runaway events Designers of battery packs are tasked with a very challenging problem: to package a set of cells as tightly as possible and minimize the amount of non-cell weight in the battery while maintaining proper temperature levels of cells, protecting against […]
Lithium-ion batteries (LIBs), used in most commercial electronics and portable devices, occupy a highly privileged position in the energy storage sector and have emerged as a versatile and efficient option for the electrification of automotive transportation and integration of renewable energies. The global market for LIB technology is projected to be over $90 billion by […]
Improving Hybrid Electric Vehicle Controls: The recent proliferation of hybrid electric vehicles has greatly complicated the world of vehicle controls engineers. Multiple energy sources and propulsion systems applied to sophisticated hybrid drivetrains necessitate a much more intricate controls strategy than conventionally powered vehicles. Determining when to distribute power to the engine, motor(s), or both is […]
As emissions regulations tighten and an electrified future grows more and more imminent, automotive engineers have been tasked with applying decades of traditional vehicle engineering knowledge to increasingly complex xEV architectures. The good news is that automakers have become very proficient at building conventionally powered vehicles – so much so that they still comprise the […]
Mathematical optimization is the search for optimal model input parameters (factors) to minimize or maximize one or more of its predicted outputs (responses). Optimization is a powerful tool to the modeler for two main tasks, both of which can enhance the modeler’s understanding of the relationship between factors and responses, and therefore the model in […]
Learn how to use GT’s advanced productivity tools to explore a microgrid’s design space. As mentioned in a previous blog posting, GT-SUITE is a powerful tool for evaluating the economics of a microgrid. However, in that previous blog post, only one combination of input variables was selected to be analyzed; for instance, the wind generation […]
Learn how to use a model to evaluate energy usage and cost of a microgrid. According to the United States’ Environmental Protection Agency, the generation of electricity accounts for over a quarter of the greenhouse gas emissions in the United States and is the second leading source of such gases, behind only transportation. It is […]
Learn about fully parametric 3D finite element (FE) analyses of battery packs and how to switch between a detailed 3D finite element and a 1D lumped mass domain.
