Title: A PEMFC hybrid electric vehicle real time control system
Author: Sun, Hongqiao
Abstract: In recent years , environmental friendly technologies and alternative energy solutions have drawn a lot of public attention due to the global energy crisis and pollution issues . Fuel cell (FC ) , a technology invented about the same time as the internal combustion (IC ) engine , is now the focus of the automotive industry again . The fuel cell vehicle (FCV ) has zero emission and its efficiency is significantly higher than the conventional IC engine power vehicles . Among a variety of FCV technologies , proton exchange membrane (PEM ) FC vehicle appears to be far more attractive and mature . The prototype PEMFC vehicle has been developed and demonstrated to the public by nearly all the major automotive manufacturers in recent years . However , to the interest of the public research , publications and documentations on the PEMFC vehicle technology are rarely available due to its proprietary nature , which essentially makes it a secured technology . This dissertation demonstrates a real world application of a PEMFC hybrid electric vehicle . Through presenting the vehicle design concept , developing the real time control system and generating generic operation principles , this dissertation targets establishing the public knowledge base on this new technology . A complete PEMFC hybrid electric vehicle design , including vehicle components layout , process flow diagram , real time control system architecture , subsystem structures and control algorithms , is presented in order to help understand the whole vehicle system . The design concept is validated through the vehicle demonstration . Generic operating principles are established along with the validation process , which helps populate this emerging technology . Thereafter , further improvements and future research directions are discussed
