According to the survey, the price of charge pile used in airport was 1 million Yuan/set, while the ordinary one in resident area is generally 80000 Yuan/set . Installation cost of airport charging pile is also high. Government subsidy policy is mainly for charging piles used by the public, and less for airports.
On the contrary, if it is a newly-built EV charging station, because of the high investment cost of land and construction, AC charging piles only account for a small proportion, and DC charging piles with strong profitability are the main ones. 4.3.2. BEVs and PHEVs
The promotion effect of direct-current charging piles on EV sales is twice that of alternating-current charging piles in the one-year simulation of our model. Increasing the number of EV charging piles has a significant impact on battery electric vehicle sales but not on plug-in hybrid electric vehicle sales. 1. Introduction
Furthermore, high-power direct-current (DC) charging piles, which are unsuitable for home installation, can provide much faster EV charging, making them ideal for urban areas, such as Madrid and Manhattan, where parking costs are high (Faria et al., 2014).
The endogenous relationships among EVs, EV charging piles, and public attention are investigated via a panel vector autoregression model in this study to discover the current development rules and policy implications from the historical panel data in China.
Up to now, the number of charging piles planned to be built in airports has exceeded 500 and the planning investment from 2015 to 2018 has exceeded 120 million RMB. 3. Airport charging infrastructure demand forecast 3.1. Airside Demand of airport airside charging facilities was predicted by ratio of vehicle to pile.
