The increasing penetration of electric vehicles (EVs) is coupling the power and transportation networks. The charging price set by the charge service provider plays a crucial role in guiding the routing and charging choices of EVs, which further affects the operation of coupled power and transportation networks. In this paper, we explore the pricing problem from the perspective of self-interested charge service providers. We adopt the mixed-user equilibrium model with elastic traffic demands to model the transportation network. The power distribution network is described as an optimal power flow model, which is relaxed into a second-order cone programming. We then propose a path generation algorithm to describe the routing and charging choices of EVs in the coupled network based on the Dijkstra method to avoid path enumeration. Simulation results validate the effectiveness of the proposed method. It proves that price competition between charge service providers can help balance the benefit of transportation network, power distribution network, and drivers.
