In this research, a novel design and operation of solar-based charging system for battery vehicle for a 50 km run is proposed. The proposal is aimed at replacing 110 existing diesel vehicles with 39 electric buses. Several operation scenarios for the charging stations are proposed and analyzed. Scenarios include two different battery charging methodologies and one hybrid option between electric buses and diesel vehicles. An energy model of the adapted electric buses is developed first. After that, load demand and needs including number of daily trips, number of passengers per hour, and hourly energy consumption are determined based on the developed model and gathered information. Results show that a 5.7 MWp photovoltaic system is required to power this transportation line with a loss of load probability of 5% and a trip cost per passenger of 2.05 USD. The simple payback period of the system is found to be 10 years, which is 40% of the system’s lifetime. The amount of CO₂ mitigated by the proposed system is estimated as 1,629,387 (kg/year). The social impact of the proposed project is found acceptable; whereas, most of the current employees will keep their jobs with higher salaries by about 145% and less working hours by 50%. Moreover, it is expected that the proposed project will significantly increase the reliability, convenience, and sustainability of the transportation process.

基于动态需求的电池车光伏充电站的新颖设计：以短期运行为例

在这项研究中，提出了一种新颖的设计和运行方式，用于50 km行驶的电池车太阳能充电系统。该提案旨在用39辆电动客车替代110辆现有的柴油车辆。提出并分析了充电站的几种运行方案。场景包括两种不同的电池充电方法以及电动巴士和柴油车辆之间的一种混合动力选项。首先开发了改装后的电动客车的能量模型。之后，根据开发的模型并收集信息确定负荷需求和需求，包括每日行程次数，每小时乘客人数和每小时能耗。结果表明，这条运输线需要一个5.7 MWp的光伏系统来供电，因此负载概率损失为5％，每位乘客的出行成本为2。05美元。系统的简单投资回收期为10年，占系统寿命的40％。一氧化碳量拟议系统缓解的₂估计为1,629,387（千克/年）。发现拟议项目的社会影响是可以接受的；而大多数现有员工将使他们的工作的薪水提高约145％，而工作时间减少50％。此外，预计拟议的项目将显着提高运输过程的可靠性，便利性和可持续性。
