Book Description
A kinetic energy recover system (KERS) captures the kinetic energy that results when brakes are applied to a moving vehicle. The recovered energy can be stored in a flywheel or battery and used later, to help boost acceleration. KERS helps transfer what was formerly wasted energy into useful energy. In 2009, the Federation Internationale de l’Automobile (FIA) began allowing KERS to be used in Formula One (F1) competition. Still considered experimental, this technology is undergoing development in the racing world but has yet to become mainstream for production vehicles. The Introduction of this book details the theory behind the KERS concept. It describes how kinetic energy can be recovered, and the mechanical and electric systems for storing it. Flybrid systems are highlighted since they are the most popular KERS developed thus far. The KERS of two racing vehicles are profiled: the Dyson Lola LMP1 and Audi R18 e-tron Quattro. Four SAE technical papers follow the preface and focus on the use of KERS technology in F1 racing. The first paper examines the factors that influence hybrid performance and enable optimization for different racing circuits. The second paper describes a Flybrid KERS designed for the 2009 F1 season. The third paper considers the development of an electric KERS for the 2009 F1 season. The fourth paper presents the challenges and opportunities of the 2014 F1 engine and powertrain rules, particularly as they pertain to KERS. This book has been published for automotive engineers who are interested in hybrid systems, energy recovery, regenerative braking, and improving acceleration. It will also be useful for powertrain designers, researchers, academics, and motorsports professionals (race engineers, team managers, and technology practitioners who design and build racing powertrains).

Book Description
Racing continues to be the singular, preeminent source of powertrain development for automakers worldwide. Engineering teams rely on motorsports for the latest prototype testing and research. Endurance racing provides the harshest and most illuminating stage for system design validation of any motorsport competition. While advancements throughout the 20th Century brought about dramatic increases in engine power output, the latest developments from endurance racing may be more impactful for fuel efficiency improvements. Hybrid powertrains are a critical area of research for automakers and are being tested on the toughest of scales. Prototype Powertrain in Motorsport Endurance Racing brings together ten vital SAE technical papers and SAE Automotive Engineering magazine articles surrounding the advancements of hybrid powertrains in motorsports. The book also includes a history of endurance racing from the World Sports Car Championship through the 24 Hours of Le Mans to the World Endurance Championship written by the author. The goal is to provide the latest concepts being researched and tested on hybrid systems that will influence vehicles for years to come - appealing to engineers and enthusiasts alike.

Optimal Control of a Flywheel-based Automotive Kinetic Energy Recovery System

Book Description
This thesis addresses the control issues surrounding flywheel-based Kinetic Energy Recovery Systems (KERS) for use in automotive vehicle applications. Particular emphasis is placed on optimal control of a KERS using a Continuously Variable Transmission (CVT) for volume car production, and a wholly simulation-based approach is adopted. Following consideration of the general control issues surrounding KERS operation, a simplified system model is adopted, and the scope for use of optimal control theory is explored. Both Pontryagin's Maximum Principle, and Dynamic Programming methods are examined, and the need for numerical implementation established. With Dynamic Programming seen as the most likely route to practical implementation for realistic nonlinear models, the thesis explores several new strategies for numerical implementation of Dynamic Programming, capable of being applied to KERS control of varying degrees of complexity. The best form of numerical implementation identified (in terms of accuracy and efficiency) is then used to establish via simulation, the benefits of optimal KERS control in comparison with a more conventional non-optimal strategy, showing clear benefits of using optimal control.

Book Description
What Is Flywheel Energy Storage The flywheel energy storage (FES) system works by keeping the energy in the system as rotational energy while simultaneously increasing the speed of a rotor (the flywheel) to an extremely high rate. When energy is removed from the system, the rotating speed of the flywheel slows down as a direct result of the theory of energy conservation. On the other hand, when energy is added to the system, the flywheel's rotational speed rises as a direct result of the principle of energy conservation. How You Will Benefit (I) Insights, and validations about the following topics: Chapter 1: Flywheel energy storage Chapter 2: Energy storage Chapter 3: Superconducting magnetic energy storage Chapter 4: Gyroscope Chapter 5: Electric motor Chapter 6: Flywheel Chapter 7: Regenerative braking Chapter 8: Magnetic bearing Chapter 9: Brushless DC electric motor Chapter 10: DC motor Chapter 11: Motor-generator Chapter 12: Revolutions per minute Chapter 13: Grid energy storage Chapter 14: Microturbine Chapter 15: Control moment gyroscope Chapter 16: Retarder (mechanical engineering) Chapter 17: London moment Chapter 18: Hybrid vehicle drivetrain Chapter 19: Kinetic energy recovery system Chapter 20: Attitude control Chapter 21: Flywheel storage power system (II) Answering the public top questions about flywheel energy storage.
