tailieunhanh - Battery Operated Devices & System

This chapter aims at providing an overview of products and systems using batteries. Here, the term product indicates any device – small or large, portable or not – powered by a battery. The term system indicates a large installation, such as an energy storage plant to back up an electricity grid, or an extended sensor network. | Battery Operated Devices and Systems From Portable Electronics to Industrial Products Gianfranco Pistoia viii Preface A number of handbooks are available to people working in the battery field where batteries are the main subject and their applications are treated in much less detail. Conversely there are no books dealing with the large spectrum of applications powered by batteries. In other words although some books cover specific topics for example portable devices electric vehicles energy storage no books that aim to summarize all battery applications have thus far been published. This book aims at bridging this gap as many applications are reported in detail and others are mentioned whereas less emphasis is put on batteries. However basic characteristics of batteries and information on the latest developments are enclosed in a dedicated chapter. As is obvious a 400-page single-author book cannot be as exhaustive as a multi-author large handbook. Nevertheless the reader may find here in addition to data on many applications links to further literature through the many references that have been included. For researchers teachers and graduate students interested in devices and systems drawing power from batteries this book will be a useful information source. In Chapter 1 all applications in the portable and industrial areas are introduced. Some market considerations follow with details on the most important sectors and a forecast to 2016 for portable devices is enclosed. In Chapter 2 basic characteristics of all primary and secondary batteries used in the applications described are reviewed. The most recent trends especially for the ubiquitous lithium ion batteries are mentioned. In Chapter 3 portable applications for example mobile phones notebooks cameras camcorders several medical instruments power tools GPS receivers are described with details on their electronic aspects. Particular emphasis is put on the devices power consumption and management for their .
