A comprehensive charging network planning scheme for promoting EV charging infrastructure considering the Chicken-Eggs dilemma

Abstract

The development of electric vehicles (EVs) cannot separated with the support of charging infrastructures. However, there has always been a paradox between them, especially in the initial phase of EVs development: the low uptake of EVs often hinders the investment enthusiasm of investors for charging infrastructure and vice versa, making them drop into a chicken-egg dilemma. For resolving the problem, a comprehensive planning scheme for EV charging networks is proposed in this paper. In the scheme, the influence mechanism of charging networks along with the developing of EVs is analyzed theoretically first, in which an inclusive analysis framework is proposed; and then around how to solve the current chicken-egg dilemma, a series of propositions and planning models are set forth and built, which not only consider the impact of charging network layout on the EVs’ charging convenience, but also discuss the cost pressure brought by the charging network construction on investors and the subsequent impact on the charging price; last, based on analytic results, aiming to promote the social uptake of EVs effectively, a relevant government subsidy scheme is proposed for charging facilities.
