In the modern world, electric vehicles (EVs) are becoming more and more prevalent, and many individuals are beginning to consider getting one for their mobility. In comparison to traditional internal combustion engine vehicles, EVs are more environmental-friendly, have higher energy conversion efficiency and produce lower noise. However, in terms of electrification of transportation, EVs also have some inherent limitations. This paper provides an overview of electrification of transportation. First, this paper will focus on the related technologies such as motor drive technology, power electronic technology and battery management. In addition, the limitations of the electrification of transportation, include range anxiety, long charging time, charging station accessibility and unsatisfactory performances in extreme temperatures, will also be presented. Despite these challenges, EVs still exhibit promises for further development and will play a leading role in transportation electrification. Considering the technological factors will help address the issues and push the future development of EV forward.
