Abstract

Developing electric vehicles (EVs) has been chosen as national strategy as solution to energy security and urban air pollution by China. China has invested much to develop electric vehicle technologies. In past 15 years, the EVs technologies have improved greatly, and in public serving field, the electric vehicle were used in large-scale. The traction battery and electric motor technologies were improved distinguished. By the EVs demonstration programs, the mainstream technology roadmap in line with China’s national conditions is becoming gradually clear. In this paper, the progress of China EVs technologies breakthrough and industrialization, pushing policies (government and local government) were summarized. The progress on EVs demonstration program was reviewed and the effectiveness was evaluated. The technology roadmap of traction battery, fuel cell, and electric motor for EVs in past years was concluded. The different technological roadmaps were evaluated by effects in demonstration program. Based on the review of the progress of China EVs R& D and demonstration program, the existing problems and future challenges in EV development were put forth. And the future electric transportation in China was proposed, including electric powertrain technologies roadmap, electric car model strategy, EV industrialization strategy. Document type: Article
