Reserving charging strategy for electric vehicles based on combined model of road-charging station-electric vehicle

Charging resources in the charging stations are limited. How to make electric vehicles get charging service with small cost is worth studying. The reserving charging model for electric vehicles is built based on the customer requirement model, considering the road condition of traffic system and available charging resources in the charging stations. All factors that influence the reserving charging are translated into weights and then being assigned to corresponding edges of traffic network graph. The Dijkstra algorithm is introduced to achieve the solution of the model built in this paper. Finally, a supposed traffic network is used to conduct a simulation, and the results show that the proposed optimization model of reserving charging for electric vehicles can satisfy users' different demands.
