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 2021 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Lithium-ion battery systems used in electric vehicles and stationary grid storage applications are composed of numerous batteries that are interconnected to create a battery pack that can satisfy the high energy and power requirements of the desired application. However, the current research in the battery modeling and control community has focused mainly on lithium-ion batteries at the single cell-level in an isolated environment where the cell-to-cell interconnections and pack heterogeneities are not accounted for. Merely applying the existing knowledge of a single cell to such a large-scale battery pack assumes "modularity", wherein modularity is defined as the ability to extrapolate the behavior of a battery pack from a single cell. Recent experimental studies presented in the literature show evidence that the assumption of modularity, in terms of electrical, thermal, and aging behavior, does not hold true. The literature further highlights that a pack reaches its end-of-life sooner than a single cell, the thermal and aging gradient behavior of the pack is non-uniform and aggravated in comparison to a single cell, and the performance of a pack is adversely affected due to cell-to-cell heterogeneities induced by manufacturing variances. As a result, the design of Battery Management Systems for a pack must take these non-uniformities or peculiarities into account while developing algorithms for modeling, estimation, and control. To that end, this dissertation adopts a bottom-up approach by developing modeling and estimation tools at the cell-level, and then extending it to the module/pack-level for efficient control. An experimentally validated electrochemical model at the single cell-level forms the basis to develop a model-based observer to estimate "non-measurable" internal battery health variables. The cell-level electrochemical model is extended to a high-fidelity module-level model by incorporating the thermal, electrical, and aging interactions between cells to analytically and quantitatively understand the effect of heterogeneities and gradients on the behavior of battery modules. Subsequently, the model is utilized to develop an optimization-based control strategy to minimize the non-uniformities, thereby improving the safety and lifespan of battery modules. The outcome of this research will open up opportunities to advance knowledge of cell- and module-level dynamics, accurate real-time prognostic algorithms, and health-conscious module-level control. This research is primarily targeted towards the transportation sector (electric vehicles), but it can be extended to stationary grid storage applications, and more importantly used to determine the feasibility of using end-of-life lithium-ion cells in "second-use" applications.

This book was released on 2016 with total page 130 pages. Available in PDF, EPUB and Kindle. Book excerpt: Increased concerns over the limited sources of energy and environmental impact of the petroleum-based transportation infrastructure have led to increasing interest in an electric transportation infrastructure. Thus, electrical vehicles (including electric vehicle (EV), hybrid electric vehicle (HEV), and plug-in hybrid electric vehicle (PHEV)) and related issues have gained a great deal of attention. Battery technology and battery management is a key component in this regard and has indeed remained as a central challenge in vehicle electrification. This thesis deals with monitoring and control of Lithium ion batteries. The objective is to provide novel solutions to some of the challenging issues from a control theoretic perspective. The research stream in this thesis is headed towards three general directions, i.e. monitoring, diagnostics, and control. The proposed monitoring approaches are introduced as model-based and data-based approaches. The main objective in model-based approaches is to employ the high-fidelity physics-based models of the battery for monitoring. In this thesis, two particle-filtering methods are proposed for state, and joint state and parameter estimation of such models. The data based approaches try to come up with new ideas to monitor the battery accurately but with minimum computational load. In this regard, two different approaches are considered. A Takagi-Sugeno fuzzy model is developed for Li-ion battery where by the virtue of multiple-model structure of T-S model, the non-linearities of battery dynamics and corresponding parameters can appropriately be accounted for, while keeping the local models linear and easy-to-implement control/estimation algorithms. As a completely different alternative, the "Dynamic Resistance" concept is introduced that is sensitive to the battery state of charge and aging. This parameter considers changes in states of active materials in the cell during charge and discharge as well as overall interface resistances that may develop during cell aging. It can bring a new dimension to battery monitoring by providing a new easy-to-monitor parameter where the aging of the battery is also taken into account. This parameter is modeled versus the state of charge and total power throughput of the battery using a Group Method of Data Handling (GMDH) neural network and the model is used to monitor the state of charge and state of health of the battery. A reliable fault diagnosis system for batteries can play an important role in enhanced performance and reliability of electric-based transportation. In this thesis, the physics of the problem is rather comprehensively reviewed, and some of the proposed models for failure mechanism are presented and some fault-detection algorithms for some common failure mechanism are developed. Finally, over-charge/discharge of the cells within a battery pack can affect the battery's health significantly, and would pose serious safety concerns as well. Thus, a cell balancing circuit is usually employed in battery packs in order to keep all the cells in balance. In this thesis, the control problem of a cell-balancing circuit, which is essentially a switched hybrid system, is addressed in a model-based framework by proposing a nonlinear model predictive control (NMPC) strategy.

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.

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.

Download or read book Understanding Second Language Acquisition written by Lourdes Ortega and published by Routledge. This book was released on 2014-02-04 with total page 321 pages. Available in PDF, EPUB and Kindle. Book excerpt: Whether we grow up with one, two, or several languages during our early years of life, many of us will learn a second, foreign, or heritage language in later years. The field of Second language acquisition (SLA, for short) investigates the human capacity to learn additional languages in late childhood, adolescence, or adulthood, after the first language --in the case of monolinguals-- or languages --in the case of bilinguals-- have already been acquired. Understanding Second Language Acquisition offers a wide-encompassing survey of this burgeoning field, its accumulated findings and proposed theories, its developed research paradigms, and its pending questions for the future. The book zooms in and out of universal, individual, and social forces, in each case evaluating the research findings that have been generated across diverse naturalistic and formal contexts for second language acquisition. It assumes no background in SLA and provides helpful chapter-by-chapter summaries and suggestions for further reading. Ideal as a textbook for students of applied linguistics, foreign language education, TESOL, and education, it is also recommended for students of linguistics, developmental psycholinguistics, psychology, and cognitive science.

Available in PDF, EPUB and Kindle. Book excerpt: This invaluable book focuses on the mechanisms of formation of a solid-electrolyte interphase (SEI) on the electrode surfaces of lithium-ion batteries. The SEI film is due to electromechanical reduction of species present in the electrolyte. It is widely recognized that the presence of the film plays an essential role in the battery performance, and its very nature can determine an extended (or shorter) life for the battery. In spite of the numerous related research efforts, details on the stability of the SEI composition and its influence on the battery capacity are still controversial. This book carefully analyzes and discusses the most recent findings and advances on this topic.
