This paper proposes a benefit allocation model for distributed electric vehicle. It considers the cooperative relationships between the stakeholders innovatively. The stakeholders consist of vehicles, charging piles, and power grids. The benefit of each stakeholder is calculated using the shapley-value approach. Based on the order of decision-making among stakeholders, the benefit allocation model includes inner layer and outer layer. The benefits of vehicles and charging piles are calculated by inner layer. The benefits of power grids are calculated by outer layer. Then, the computational flow of the model is presented according to the nested relationships in proposed benefit allocation model. Case studies validate the feasibility of the proposed model. Result shown that the proposed model can increase the gain of trolley compared to conventional.
