摘要
Electrification of vehicular systems, partial or complete, has emerged as an attractive and sustainable alternative for futuristic transportation systems. This so-called electric vehicular technology (EVT) has engaged auto-manufacturers and researchers to primarily focus on fuel economy, driving range, performance, and costs. These parameters are influenced by the design and performance of electric propulsion system (EPS) for vehicular application and its suitable integration with various electrical and mechanical apparatus. This paper primarily presents a comprehensive study of EPS. To present the study in synthesis, a survey of important constituents of EPS is first carried out with techno-economic perspectives. Contemporary configurations of conventional and electrified vehicles are then discussed along with their respective advantages and limitations. EPS is considered to be the heart of EVT, and, therefore, components of a standard EPS are discussed and comparative analyses are carried out in terms of present trends, ongoing technological advancements and future challenges. In addition, power flow control and management algorithms for EVT are also briefed.
