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.
Highlights
China is facing urgent energy security and urban air pollution problems
Since the 10th 5-year plan of developing energy saving and new energy vehicles, China has invested more than 100M RMB for Electric vehicles (EVs) key technologies break through and industrialization
[13] In newly released ‘accounting methods for corporate average fuel consumption of passenger cars’, it is stated that the electric vehicle and plugin electric vehicle with AER more than 50km can be ranked as zero fuel consumption and the numbers can be accounted as 5 times[14]
Summary
The issues of PM2.5 harmful to human health has caught highly concern of China government. The tailpipe emission is the main source of harmful PM2.5 in China[1,2,3]. Electric vehicles (EVs) are becoming of increasing interest in world with an intensified focus on the climate and CO2-emissions. China has issued many policies to push the EVs development. Since the 10th 5-year plan of developing energy saving and new energy vehicles, China has invested more than 100M RMB for EVs key technologies break through and industrialization. In 11th 5-year plan, 1.16 billion RMB had been invested in EVs R&D. Year plan, China MOST will invest 3billion into electric vehicle technology researching [4,5,6]
