摘要
为对比"夜间慢速充电+白天快速充电"、"夜间慢速充电"两种不同的整车直接充电模式下,电动公交车的车辆发车计划与充电费用,考虑时刻表、电量限制、充电站距离、允许车辆等待发车时间阈值的影响,建立并运行模型。结果发现,两种模式需要的最小公交车辆数、单日需要的充电费用均不同,建议企业应考虑车辆数、充电费用等因素选取适合的充电模式。此外,还对公交车前往充电站的距离、公交车到达站点等待发车的时间阈值与充电费用的关系进行了敏感性分析,据此建议合理设置充电站位置,并根据具体条件设置合适的等待发车时间阈值,以减少充电费用。
In order to compare departure planning and charging cost of electric bus under two different direct charging modes of "night slow charging + day fast charging" and "night slow charging", the influence of timetable, electric power limit, charging station distance and allowable waiting time threshold are considered, and a model is established. It is found that the minimum number of buses required by the two modes and the charge cost per day are different. It is suggested that electric bus operators should consider the number of buses, charge cost and other factors to select the appropriate charging mode. In addition, the sensitivity analysis on the impact of the distance from the terminal to the charging station and the waiting time of the bus arriving at the charging station on the charging cost is carried out. It is suggested that the charging station location should be set reasonably and the appropriate waiting time threshold should be set according to the specific conditions to reduce the charging cost.
