铁路综合交通枢纽电动汽车充电桩系统设计

在综合交通枢纽的快速发展和新能源汽车迅速增长的背景下,系统地分析了已建成的综合交通枢纽的功能定位及空间布局,提出综合交通枢纽的新能源电动汽车的充电方案及配电系统计算。从铁路综合枢纽内的公车枢纽、社会公共停车场、出租车停车场等重点区域停放电动汽车的充电需求入手,结合每个停车区域的停车数量或规划的公交路线、停运时间、最大充电时间,针对性地分析了公交车辆、私家车、出租车、社会车辆的充电方式,计算出充电桩数量,提出充电计费方式和配电系统设计方案。研究结果表明,该方案指导了铁路综合交通枢纽内的电动汽车充电桩的系统设计,优化了充电系统供电方案,控制了综合枢纽的建设投资和运营成本。

System design of charging pile system for electric vehicle in railway comprehensive communication hub

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.
