Under the background of the rapid development of integrated transportation hub and the rapid growth of new energy vehicles, this paper systematically analyses the functional orientation and spatial layout of the built integrated transportation hub, and puts forward the charging scheme and distribution system calculation of new energy electric vehicles in integrated transportation hub. Starting with the charging demand of parking electric vehicles in key areas such as bus hub, public parking lot and taxi parking lot in railway comprehensive hub, and combining the number of parking areas or the planned bus route, parking time and maximum charging time in each parking area, the charging mode of bus, private car, taxi and social vehicle is analyzed pertinently, the number of charging piles is calculated, and the billing mode and the design of distribution system are proposed. The results show that the scheme guides the system design of charging piles for electric vehicles in railway integrated transport hub, optimizes the power supply scheme of charging system, and controls the construction investment and operation of integrated transport hub.
