Modular Mobile Charging Facility Layout Optimization Method and Deployment Strategy

This paper investigates the layout planning and deployment strategy for modular mobile charging facilities, a novel type of charging facilities for electric vehicles. Firstly, an electric vehicle user travel mechanism model is established to predict the spatial and temporal distribution of charging demand at the node level. Secondly, a socket component planning model is developed for the upper layer with the objective of optimal operator revenue. Then, a charger components optimal deployment model is established for the lower layer based on the vehicle routing problem. Finally, an algorithm based on iteration and feedback is designed to solve it. The example simulation results show that, as an effective complement to fixed charging facilities, the modular facilities can reduce the operator's operational cost and increase the equipment utilization rate while meeting the users' charging demand.
