In order to examine the effects that charging/discharging have on the demand in electricity, we analyze scenarios based on the simulation results of the EVs＇ parking location, parking duration and the battery state of charge. From the simulation, result under the ownership rate of EVs in the Nagoya metropolitan area in 2020 is about 6%, which turns out that the total CO2 emissions have decreased by 4% although the situation of urban transport is not changed. After calculating the electricity demand in each zone using architectural area and basic units of hourly power consumption, we evaluate the effect to decrease the peak load by V2G （vehicle-to-grid）. According to the results, if EV drivers charge at home during the night and discharge at work during the day, the electricity demand in Nagoya city increases by approximately 1%, although changes in each individual zone range from -7% to ＋8%, depending on its characteristics.展开更多

As an effective alternative to conventional vehicle, electric vehicle in recent years has been widely concerned due to its characteristics of energy saving and environmental protection. To identify the key influential factors in the development of EV industry in China is conducive to formulating reasonable industrial development strategy and meeting market demand of consumers. In this paper, the key factors in the development of EV industry are obtained by analyzing Baidu Index in each time period.展开更多
