Abstract With the popularization of Internet of vehicles, cloud computing, and big data applications, the sharing electric vehicle rental business, which represents “Internet + travel”, has a broad development space due to its flexibility, convenience, and environmental protection. The time-space distribution of the car-sharing and car-sharing customers does not match, which is the key problem faced by the car-sharing operators to improve their revenue. Based on the network flow model, taking into account the impact of electric vehicle charging on the status of vehicles that can provide rental services, and at the same time realizing the analysis of the supply and demand of the rental business in the time and space dimensions; and combining the characteristics of the rental business, it proposes the conservation of traffic flow at the rental site and the sharing vehicle status transfer conservation constraints. Taking the operator's maximum net income as the optimization goal in the dispatch cycle, considering the road network, car, rental demand and charging network constraints, a mixed integer linear model of sharing electric vehicle optimal dispatch is established to optimize the decision of vehicle deployment plan and charging plan. The calculation example shows that the optimized scheduling strategy can improve the revenue and user satisfaction of shared electric vehicle operators.
