Defined as a type of mobile robot, smart electric vehicle is changing the quality of human life, spacetime value and cultural integration. In this paper, the development of smart electric vehicle is detailed introduced as well as its technological level and related core technololies at home and abroad. The information perception, electric vehicle charging pil, and battery management system are focused. The related core technololgies in electric vehicle, such as sensing technology, data fusion, control algorithm, and communication technology, are summarized. With the development of novel intelligent sensing technology, such as large data and cloud computing, future intelligence perception will completely change the pattern recognition of traditional machine vision technology on the underlying characteristics. In the process of industrialization of intelligent electric vehicles also need to address human nature, security, reliability and legal and moral issues. The rapid development of intelligent electric vehicle technology will change the concept of time and space of mankind, but also will have a farreaching and revolutionary impact on the transport industry.
