Beard, 2019-05-10 Publisher's Note: Products purchased from Third Party sellers are not guaranteed by the publisher for quality, authenticity, or access to any online entitlements included with the product.Thoroughly revised, comprehensive coverage of battery technology, characteristics, and applicationsThis fully updated guide offers complete coverage of batteries and battery usage―from classic designs to emerging technologies. Compiled by a pioneer in secondary lithium batteries, the book contains all the information needed to solve engineering problems and make proper battery selections. You will get in-depth descriptions of the principles, properties, and performance specifications of every major battery type. Linden’s Handbook of Batteries, Fifth Edition, contains cutting-edge data and equations, design specifications, and troubleshooting techniques from international experts. New chapters discuss renewable energy systems, battery failure analysis, lithium-ion battery technology, materials, and component design. Recent advances in smartphones and hybrid car batteries are clearly explained, including maximizing re-chargeability, reducing cost, improving safety, and lessening environmental impact.Coverage includes:•Electricity, electrochemistry, and batteries•Raw materials•Battery components•Principles of electrochemical cell operations•Battery product overview•Electrochemical cell designs (platform technologies)•Primary batteries•Secondary batteries•Miscellaneous and specialty batteries•Battery applications•Battery industry infrastructure |
| c&d technologies ups12 300mr: Thermal Guidelines for Data Processing Environments ASHRAE (Firm), 2012 There is often a mismatch of IT equipment environmental requirements with adjacent equipment requirements or with facility operating conditions and therefore a strong need to find common solutions and standard practices that facilitate IT equipment interchangeability while preserving industry innovation. Thermal Guidelines for Data Processing Environments provides a framework for improved alignment between IT equipment hardware manufacturers (including manufacturers of computers, servers, and storage products), data center designers, and facility operators and managers. This guide covers five primary areas: equipment operating environment guidelines for air-cooled equipment (six classes are defined), environmental guidelines for liquid-cooled equipment (five classes are defined), facility temperature and humidity measurement (to evaluate data center health), equipment placement and airflow patterns (a hot-aisle/cold-aisle layout is recommended), and equipment manufacturers' heat load and airflow requirements reporting. In reaction to the industry trend of increased energy efficiency for data center operation, this third edition of Thermal Guidelines for Data Processing Environments provides groundbreaking, vendor-neutral information that will empower data center designers, operators, and managers to better determine the impact of varying design and operation parameters. This book is the first in the ASHRAE Datacom Series, authored by ASHRAE Technical Committee 9.9, Mission Critical Facilities, Technology Spaces and Electronic Equipment. This series provides comprehensive treatment of datacom cooling and related subjects. |
| c&d technologies ups12 300mr: International Freight Transport Anthony Beresford, Stephen Pettit, 2017-03-03 International Freight Transport presents the key changes and issues in the fast-moving industries of trade and transport. It includes coverage of regional trade groupings, the emergence of new large economies (i.e. BRIC countries), and pivotal regions such as the Middle East and Central America where major projects, such as new and widened canals, are underway or planned. These changes could redraw the trade map with major implications for transport patterns and solutions. Blending geography, economics, politics and trade, International Freight Transport provides insight into a wide range of topics, including: globalisation; demand versus supply; buyers and sellers; transport regulation, geography, modes and methods; transport ownership; alliances; and safety and security. The book is the only comprehensive and accessible book on international transport available. |
