Abstract
In order to adapt the matching and planning requirements of charging station in the electric vehicle (EV) marketization application, with related layout theories of the gas stations, a location model of charging stations is established based on electricity consumption along the roads among cities. And a quantitative model of charging stations is presented based on the conversion of oil sales in a certain area. Both are combining the principle based on energy consuming equivalence substitution in process of replacing traditional vehicles with EVs. Defined data are adopted in the example analysis of two numerical case models and analyze the influence on charging station layout and quantity from the factors like the proportion of vehicle types and the EV energy consumption at the same time. The results show that the quantitative model of charging stations is reasonable and feasible. The number of EVs and the energy consumption of EVs bring more significant impact on the number of charging stations than that of vehicle type proportion, which provides a basis for decision making for charging stations construction layout in reality.
Highlights
The widespread use of the combustion engine vehicles has become an important factor of energy consumption and environmental pollution [1, 2], which leads the electric vehicle (EV) to get more attention owing to its distinguished features of genuine zero emission and high efficiency [3, 4]
In China, the EV has become an essential part of the new energy strategy and smart grid field [5, 6]
Feng et al [18] presented a novel method for EV charging station planning based on the weighted Voronoi diagram
Summary
The widespread use of the combustion engine vehicles has become an important factor of energy consumption and environmental pollution [1, 2], which leads the EV to get more attention owing to its distinguished features of genuine zero emission and high efficiency [3, 4]. Johannes et al [16] established a dynamic spatial model of the development of a charging infrastructure for EVs to allocate the need for charging stations in space. Since the charging time of electric vehicles is longer than conventional fuel vehicles, taking up a longer time for parking, the planning and layout of the charging stations are subject to geographical location conditions, including distribution capacity, available space, time of waiting for charging, peripheral facilities, and many other factors, especially the cities with larger population density and scarce land resources. Theoretical research of charging station construction and planning and its scale and influencing factor analysis is a relative effective planning measure at the early stage of electric vehicles. The influence and sensitivity of the factors including the number of EVs, the proportion of vehicle type, and the electricity consumption of EVs are analyzed
