在城市中应用电池电动公交车（BEB）是减少温室气体排放和原油依赖的良好手段。受续航里程和充电时间的限制，电池交换站似乎是目前纯电动公交车补充能量的最佳选择。本文提出了一种新的方法来规划和设计一个电动公共交通系统下的电池交换模式，其中包括电池电动巴士，路线，调度，电池交换站等，从而提出了新的电池电动巴士车队的路由和调度策略。在对电池交换和充电需求分析的基础上，建立了一种计算电池交换站最优规模的算法，包括电池交换系统规模、电池充电系统规模、电池组规模和输出功率容量。以青岛市薛家岛换电站为例，建立了数值模拟程序，验证了本文方法的有效性。结果表明，该方法可以优化系统规模，使其满足等效运行状态的要求。此外，对不同电池容量和充电电流下的尺度进行了灵敏度分析。未来随着动力电池制造和充电技术的发展，可有效降低换电站的规模和成本。
Applying battery electric buses (BEBs) in the city is a good means to reduce the increasing greenhouse gas emissions and crude oil dependence. Limited by the driving range and charging time, battery swap station seems to be the best option for battery electric buses to replenish energy currently. This paper presents a novel method to plan and design an electric public transport system under battery swap mode, which comprised of battery electric buses, routes, scheduling, battery swap station, etc. Thus, new routing and scheduling strategies are proposed for the battery electric bus fleets. Based on swapping and charging demand analysis, this paper establishes an algorithm to calculate the optimal scales of battery swap station, including scales of battery swapping system, battery charging system and battery packs, and power capacity of output. Regarding the case of Xuejiadao battery swap station serving 6 BEB routes in Qingdao, China, a numerical simulation program is established to evaluate the validity of our methods. The results reflect that our methods can optimize the system scales meeting an equivalent state of operation demand. In addition, sensitivity analyses are made to the scales under different values of battery capacity and charging current. It suggests that the scales and cost of battery swap station can be effectively reduced with the development of power battery manufacture and charging technology in future.
