Opis

Starting from fundamental theory, equations, model development, solution methodology to algorithms, this monograph connects fundamental electrochemistry of lithium batteries to controlling processes and eventually to on-board battery state estimators.

This book is unique to be the only one completely dedicated for battery modeling for all components of battery management system (BMS) applications. The contents of this book compliment the multitude of research publications in this domain by providing coherent fundamentals. An explosive market of Li ion batteries has led to aggressive demand for mathematical models for battery management systems (BMS). Researchers from multi-various backgrounds contribute from their respective background, leading to a lateral growth. Risk of this runaway situation is that researchers tend to use an existing method or algorithm without in depth knowledge of the cohesive fundamentals-often misinterpreting the outcome. It is worthy to note that the guiding principles are similar and the lack of clarity impedes a significant advancement. A repeat or even a synopsis of all the applications of battery modeling albeit redundant, would hence be a mammoth task, and cannot be done in a single offering. The authors believe that a pivotal contribution can be made by explaining the fundamentals in a coherent manner. Such an offering would enable researchers from multiple domains appreciate the bedrock principles and forward the frontier.Battery is an electrochemical system, and any level of understanding cannot ellipse this premise. The common thread that needs to run across-from detailed electrochemical models to algorithms used for real time estimation on a microchip-is that it be physics based. Build on this theme, this book has three parts. Each part starts with developing a framework-often invoking basic principles of thermodynamics or transport phenomena-and ends with certain verified real time applications. The first part deals with electrochemical modeling and the second with model order reduction. Objective of a BMS is estimation of state and health, and the third part is dedicated for that. Rules for state observers are derived from a generic Bayesian framework, and health estimation is pursued using machine learning (ML) tools. A distinct component of this book is thorough derivations of the learning rules for the novel ML algorithms. Given the large-scale application of ML in various domains, this segment can be relevant to researchers outside BMS domain as well.The authors hope this offering would satisfy a practicing engineer with a basic perspective, and a budding researcher with essential tools on a comprehensive understanding of BMS models.

Dr. Hariharan’s research focuses on mathematical modeling of lithium batteries for industrial applications. During his research career, he has had the opportunity to develop electrochemical, impedance spectroscopy as well as equivalent circuit models for lithium batteries. In addition, Dr. Hariharan was also involved in developing battery state estimator algorithms and thermal analysis of cells as well as battery packs. During his tenure with General Motors R&D, he collaborated with algorithm engineers responsible for implementing on-board state estimators for electric vehicle (EV) programs. His research experience with various approaches in battery modeling would enable a successful monograph on state of the art in this emerging area.

Piyush Tagade is a Research Staff Member at Samsung Advanced Institute of Technology, Samsung R&D Institute, Bangalore, India. He holds a PhD degree in Aerospace Engineering from Indian Institute of Technology Bombay, India. Before joining Samsung, he was a postdoctoral research associate at Korea Advanced Institute of Science and Technology, Republic of Korea and Massachusetts Institute of Technology, USA. In his scientific research work he is mostly concerned with developing efficient Bayesian framework for large-scale system simulators. His areas of interest include Bayesian inference, uncertainty propagation, data assimilation, optimization and machine learning.

Sanoop Ramachandran was born in Kerala, India in 1981. He got his BSc degree (2001) from the University of Calicut, Kerala, India.
