Energy Management in Electric Vehicle Engineering

ABSTRACT\ud ENERGY MANAGEMENT IN ELECTRIC VEHICLE ENGINEERING\ud by\ud ?? Friedrich J. Kirk 2011\ud Master of Science in Interdisciplinary Studies\ud Electric Vehicle Engineering\ud California State University, Chico\ud Spring 2011\ud The world is now facing a number of important problems brought on by humanity???s\ud use of carbon-based fuels. One of the primary uses of these fuels is for transportation.\ud There is a need to make highway capable electric vehicles accessible to the average\ud commuter. The high initial cost of storing the energy is one of the primary barriers to\ud entry for electric vehicles. Energy management technology has not been leveraged to\ud provide energy in a manner that is congruent with the user???s needs. A user configurable\ud energy storage system would allow users to find their own solution to the costperformance\ud question.\ud The scope of this project is to design and build an integrated energy management\ud system that includes all necessary components to store energy for an electric\ud vehicle. Every aspect of the energy management system is covered. The goal is to design,\ud build and test a ???plug & play??? modular energy storage system.\ud Power converters and issues affecting safety, efficiency, and electromagnetic\ud interference are discussed. Details specific to lithium ion batteries are covered, including\ud charging modes and cell protection. The battery management system is used for executive\ud control of the charger and the charger???s local and executive control modes are discussed.\ud Battery pack design and requirements such as safety issues specific to lithium ion\ud batteries are introduced. Energy management system features such as delayed charging,\ud user interface design, and cell balancing are covered.CSU, Chic
