Available in PDF, EPUB and Kindle. Book excerpt: Abstract : This thesis extends the full-scale electrochemical model for a Lithium-ion battery based on the porous electrode theory to incorporate aging mechanisms of solid electrolyte interface formation, cyclic electrode degradation, and lithium plating during overcharge, automotive vibrations, mechanical stress, and cell temperature, as reported in the existing literature. Further, the thesis presents the scope of the parameters used in the model to enable designers to extend the equations for new mechanisms and variability of other parameters. An increased set of equations makes the complexity of the model even higher, and it would be very computationally complex to simulate this model. This makes this model unsuitable for inexpensive processors of mobile applications like an automotive battery management system while increasing the uncertainty faced by PDE solvers. However, as the physical models get close to an actual lithium-ion battery behavior, they could accelerate its development, shortening the design life of batteries.

This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Adoption of electric vehicles has seen major growth in recent years with widespread consumer and commercial adoption. However, one major concern in automotive applications is cell capacity loss over time, leading to lower vehicle range. To address this, aging models are developed that predict capacity loss based on the varying storage, cycling, and environmental conditions a cell may experience. Aging models can range in complexity from simple Ah-throughput models to first principles models. First principles models considered the underlying physical and chemical degradation mechanisms that damage the cell, such as growth of the Solid-Electrolyte Interphase (SEI) or Loss of Active Material (LAM). They are also fully integrated with high-fidelity electrochemical cell models, so cell degradation due to SEI growth or LAM directly affects the voltage behavior of the cell model. To reduce the computational burden, various reduced-order aging models have been proposed that apply simplifications to first principles models while retaining a high level of accuracy. However, the simplifying assumptions used typically involve neglecting the impact of degradation on cell voltage behavior in favor of providing a direct prediction of capacity loss. Since these assumptions result in a static voltage behavior throughout life, these reduced-order models lose the ability to predict the complex interaction between different aging mechanisms and limit the model's ability to extrapolate beyond its calibration horizon. In this thesis, a computationally efficient reduced-order aging model is proposed that accurately predicts the underlying impact of SEI growth on the cell voltage, and a framework for LAM model calibration is provided. With the physics-based SEI layer growth implementation, prediction of capacity loss manifests as a natural result of the chemistry of the cell model changing due to SEI growth. To calibrate the model, novel techniques were developed to estimate both SEI growth and LAM to overcome limitations in the available experimental data. Then the capacity prediction and underlying physics were validated using experimental data and incremental capacity/voltage analysis, proving strong predictive capability and physical meaning.

Download or read book Analysis of Aging Severity Factors for Automotive Lithium Ion Batteries written by Alexander K. Suttman and published by . This book was released on 2010 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: As any battery is charged and recharged through its use, the maximum power and capacity of the battery slowly decrease. This phenomenon, termed 'aging', is of particular concern in fields such as the automotive industry where long battery life is essential. Furthermore, this 'aging' is present with all battery chemistries. While the 'aging' can be traced back to a multiplicity of internal microscopic material degradation processes, the purpose of this project was to identify the macroscopic conditions under which batteries age most rapidly in order to predict or even extend useful battery life by avoiding these conditions. Specifically, this project focuses on advanced Li-ion batteries by identifying simplified electrical models of battery characteristics and tracking the slow evolution of the model parameters through the life of the battery. This analysis was performed for many batteries which underwent different conditions of aging (state of charge and current levels) and leverages several years of experiments at the Center for Automotive Research. The initial results indicate it is feasible to track this aging process by this methodology and that this aging process can be simply modeled by a slow dynamic model which depends on the severity of the operating conditions. Further, this approach could be performed in-situ in the vehicle with simple measurements readily available.

This book was released on 2015-11-12 with total page 253 pages. Available in PDF, EPUB and Kindle. Book excerpt: The aim of this book is to review innovative physical multiscale modeling methods which numerically simulate the structure and properties of electrochemical devices for energy storage and conversion. Written by world-class experts in the field, it revisits concepts, methodologies and approaches connecting ab initio with micro-, meso- and macro-scale modeling of components and cells. It also discusses the major scientific challenges of this field, such as that of lithium-ion batteries. This book demonstrates how fuel cells and batteries can be brought together to take advantage of well-established multi-scale physical modeling methodologies to advance research in this area. This book also highlights promising capabilities of such approaches for inexpensive virtual experimentation. In recent years, electrochemical systems such as polymer electrolyte membrane fuel cells, solid oxide fuel cells, water electrolyzers, lithium-ion batteries and supercapacitors have attracted much attention due to their potential for clean energy conversion and as storage devices. This has resulted in tremendous technological progress, such as the development of new electrolytes and new engineering designs of electrode structures. However, these technologies do not yet possess all the necessary characteristics, especially in terms of cost and durability, to compete within the most attractive markets. Physical multiscale modeling approaches bridge the gap between materials’ atomistic and structural properties and the macroscopic behavior of a device. They play a crucial role in optimizing the materials and operation in real-life conditions, thereby enabling enhanced cell performance and durability at a reduced cost. This book provides a valuable resource for researchers, engineers and students interested in physical modelling, numerical simulation, electrochemistry and theoretical chemistry.
Download or read book Modelling Li ion Battery Aging for Second Life Business Models written by Lluc Canals Casals and published by . This book was released on 2018 with total page 165 pages. Available in PDF, EPUB and Kindle. Book excerpt: Electric vehicles are, slowly but steadily, entering into the automotive market. The slow entry is caused, basically, by the high cost of their batteries. Additionally, electric vehicle batteries are considered not useful for traction purposes when they have lost between 20 or 30% of its capacity. At this point, batteries should be recycled by the phew companies capable to do so in Europe, knowing that management of batteries as industrial waste until the recycling factory costs money. In the search of economical incentives and trying to eliminate the recycling costs, the idea of electric vehicle battery reuse for stationary applications appeared, which will take advantage from the benefits of reused batteries selling or by the profit obtained from the 2nd life use. This thesis analyzes the different electric vehicle batteries actually in the market, studying the aspects that should be modified and that have to be taken into account when repurposing them. Moreover, it analyzes the remanufacturing costs taking into account the actual battery checking methods. In order to improve these processes, a novel battery state of health estimation methodology is developed using on-board data. This new methodology observes the voltage recovery evolution when the car stops and relates it to battery aging. This thesis studies the rest of useful life in the different possible applications for second life developing an aging model using Matlab and Simuling tools. This model includes the principal aging factors of a battery and, based on current load requirements and temperature profiles of different stationary applications, it determines their expected lifetime. The presented values can be used, afterwards, for economic evaluation, business model calculations, amortization periods and maintenance schedules. Finally, this thesis finishes with an environmental analysis based on the global warming effect produced by the electric vehicle and the battery reuse during its second life, evaluating their environmental presupposed advantages against internal combustion engine vehicles and the battery reuse in each possible business case. This thesis concludes that electric vehicle battery reuse is surely going to take place sooner or later. The electricity grid is waiting for affordable energy storage systems and battery reuse is foreseen as a good option.
