Heavy-Duty Electric Vehicles: From Concept to Reality presents a step-by-step design and development guide for heavy-duty electric vehicles. It also offers practical insights based on the commercial application of an electric city bus. Heavy-duty electric vehicle design is challenging due to a lack of clear understanding of the government policies, R&D directions and uncertainty around the performance of various subsystems in an electric powertrain. Therefore, this book discusses key technical aspects of motors, power electronics, batteries and vehicle control systems, and outlines the system integration strategies necessary for design and safe operation of electric vehicles in practice. This comprehensive book serves as a guide to engineers and decision makers involved in electric vehicle development programs and assists them in finding the suitable electric powertrain solution for a given heavy-duty vehicle application. - Offers an overview of various standards and regulations that guide the electric vehicle design process and a comprehensive discussion on various government policies and incentive schemes propelling the growth of heavy electric vehicle markets across the world - Provides a comparative evaluation of different electric drivetrain concepts and a step-by-step power calculation guide for heavy-duty electric powertrain - Explains material selection and manufacturing methods for next generation batteries - Discusses key elements and design rules for creating a robust high voltage energy storage system, appropriate packaging and its support systems including charging network - Includes a concise description of torque mapping, power management and fault handling strategies for inverter drive and control systems - Features case studies to better understand complex topics like charging system requirements and vehicle control system diagnostics
Letting go of the past means risking it all… After years of living with her controlling father and brothers, Kimberly Lloyd simply wants to make her own decisions. Living in Bar Harbor, Maine, working as a paramedic is the first step to free herself from her overbearing family. She won’t let anyone take her job or new friendships from her. When tragedy ended his military career, Rico Montenegro fled to Mount Desert Island and found solace as a park ranger. He’s finally letting people in and forging close relationships. When his friendship with Kim seems to be turning into something more, he fears his past mistakes will keep him from moving forward. A series of deaths on Otter Cliffs—with victims eerily similar to Kim—leave Rico determined to safeguard his new love. But his protectiveness threatens to drive Kim away…and straight toward the killer.
What’s lost can be found again… Five summers ago, Chelsea Woodridge met, fell in love with, and married ranger Theodore Lapierre in beautiful Bar Harbor. It was perfect, until her father’s manipulations cost her not only the man she loved but their child, spiraling her into a fog that lasted for years. Theo loved Chelsea the instant he saw her and thought the feelings returned. Her visit with her father has him questioning her love when instead of returning, he gets a note of rejection. And several months later, a newborn on his doorstep. With her father now dead, Chelsea returns to Maine, where she’d been happiest. Theo’s presence brings back the pain of the past but seeing the daughter she thought was dead devastates her. How could Theo have thought she didn’t want her own child? More importantly, how could her father have lied to her about her baby? Rebuilding the marriage may take more than either can manage. They shared love once, but Chelsea still holds secrets. Ones that can’t be revealed if she wants to have a life with Theo and their daughter.
Technology constantly evolves, usually slowly and insidiously – but always just as surely. Things that are currently being developed in laboratories will be in the public domain as different products and applications perhaps as soon as in a few years’ time, and as more refined versions in around ten years’ time. This book deals with the future of technology, and explores the influence new technologies may have on life within the next twenty years. It is divided into three parts, the first of which discusses technological development and the forces and counter-forces related to it. This section also reviews how advances in technology are forecasted, and what kinds of parties make these predictions, and provides examples of forecasts for the next couple of decades. The second part of the book investigates the various areas of technology and their related trends. This section discusses current technological studies which may have concrete impacts in everyday life in a few decades, such as those in the fields of energy, transportation, biotechnology, materials, ICT, robotics, medical technology and space technology. The third part of the book introduces the authors’ visions of how technology may develop by 2035, and presents three different scenarios, or future worlds. These will demonstrate the possible directions in which technological development can take us. The scenarios are introduced through two main characters, Romeo and Juliet (adapted from Shakespeare’s play) in the year 2035. Even though technology is constantly changing, the writers believe that, even years into the future, the significance of human relations will remain the greatest influence on human life.
