In order to respond to the energy crisis and environment problem, countries carry out their research and promotion about electric vehicles. As the ten cities one thousand new energy buses started in 2009, the new energy vehicles have been greatly developed in China, while the development of electric vehicles is not that good. This paper selects four cities-Los Angeles, Kanagawa, Hamburg, Amsterdam-that promote electric vehicles successfully and deeply analyzes the development of electric vehicles in these four cities and analyzes the factors that affect the development of electric vehicles in three aspects-city environment, government and stakeholders. Then the paper discusses the promotion ways and role of government and consumer. Finally, the paper offers some suggestions to promote electric vehicles in China: focusing on feasibility and adaptability of electric vehicles, playing government`s leading role, improving low-awareness and acceptance of electric vehicles and focusing on user requirements.

In the most recent period, gasoline and diesel are still the main energy sources of the car. The new energy vehicles need to be solved in the near future. The new medium of the internal combustion engine and the alternative combustion vehicles. The medium-term scheme is to reduce the fuel consumption and emissions of the hybrid vehicles. The program is pure electric vehicles and fuel cell vehicles. While new energy vehicles offer a wide range of alternative fuels for fuel-based fuels, hybrid vehicles, and fuel cell vehicles that use fuel and power systems for automotive hydrogen fuel cells, but because of the current level of technological development, search for a wide range of alternative fuels, the development of closer to the market of hybrid technology, is the development of alternative energy is the most practical step. And pure electric vehicles and hydrogen fuel cells because of its technology is still difficult to achieve a revolutionary breakthrough, it is difficult to become the automotive industry's recent development goals. In today's social situation, the hybrid can be a better solution to fuel consumption problems and pollution problems. It will mainly introduce the advantages and feasibility of hybrid.

In order to evaluate the economy performance of new energy vehicles, the life-cycle cost theory is applied. A formula of quantitative analysis in combination is adopted to have in-depth study on the life-cycle cost of new energy vehicles. Analysis and argumentation are also conducted in comparison pure-electric vehicles, hybrid electric vehicles and traditional oil-fueled vehicles under the condition of present oil price, the analysis result shows that if despite the battery cost, PEV costs the fewest because of the lowest operation costs and energy costs, the cost of HEV is at a middle level. Therefore, customers and manufacturers may become more interested in PEV than in other solutions. Furthermore, a decision tool by setting up a cost model based on linear programming theory is developed, economic influence factors for the application of new energy vehicles are further discussed through sensitivity analysis.

Abstract New energy vehicles are mainly pure electric new energy vehicles. Pure electric vehicles are powered entirely by batteries, as well as power generators. With the improvement of economic level, scientific and technological progress, as well as the emphasis on energy conservation and emission reduction, the development of pure electric vehicles is more rapid, computer simulation design technology helps to adjust and optimize the dynamic performance of electric vehicles, in 2019, the output of pure electric vehicles reached 56,700, it is expected to reach about 100,000 by 2022. However, due to the limitation of battery technology, the average range of pure electric vehicles is about 200km. So it can only withstand short distances between cities.

Vehicle ownership is one of the most important factors affecting fuel demand. Based on the forecast of China’s vehicle ownership, this paper estimates China’s fuel demand in 2035 and explores the impact of new energy vehicles replacing fossil fuel vehicles. The paper contributes to the existing literature by taking into account the heterogeneity of provinces when using the Gompertz model to forecast future vehicle ownership. On that basis, the fuel demand of each province in 2035 is calculated. The results show that: (1) The vehicle ownership rate of each province conforms to the S-shape trend with the growth of real GDP per capita. At present, most provinces are at a stage of accelerating growth. However, the time for the vehicle ownership rate of each province to reach the inflection point is quite different. (2) Without considering the replacement of new energy vehicles, China’s auto fuel demand is expected to be 746.69 million tonnes (Mt) in 2035. Guangdong, Henan, and Shandong are the top three provinces with the highest fuel demand due to economic and demographic factors. The fuel demand is expected to be 76.76, 64.91, and 63.95 Mt, respectively. (3) Considering the replacement of new energy vehicles, China’s fuel demand in 2035 will be 709.35, 634.68, and 560.02 Mt, respectively, under the scenarios of slow, medium, and fast substitution—and the replacement levels are 37.34, 112.01, and 186.67 Mt, respectively. Under the scenario of rapid substitution, the reduction in fuel demand will reach 52.2% of China’s net oil imports in 2016. Therefore, the withdrawal of fuel vehicles will greatly reduce the oil demand and the dependence on foreign oil of China. Faced with the dual pressure of environmental crisis and energy crisis, the forecast results of this paper provide practical reference for policy makers to rationally design the future fuel vehicle exit plan and solve related environmental issues.

To improve the service life and performance of lithium cells in new energy electric vehicles, the thermal management system of lithium cells in new energy vehicles is analyzed through simulation experiments in this research. Firstly, the calculation model of set of cells and cooling structure is built, and then a lithium cell management system is designed. On this basis, the cooling structure of lithium cell is optimized. Finally, the simulation results of the calculation model and the simulation results of the heat dissipation performance of the thermal management system in the cooling structure of lithium cell are analyzed, including influence of three factors (coolant flow, inlet temperature of coolant, and discharge multiple) on the heat dissipation of the thermal management system of lithium cell. The results show that the calculation model constructed in this research is feasible. When the optimal structure, coolant flow value, inlet temperature of coolant, and discharge multiple are determined, the thermal management system of lithium cell has a good cooling effect under the optimal parameters. Therefore, the results of this research can provide a good theoretical basis for heat management and heat dispersion technology in new energy electric vehicles.
