摘要：
电池交换站（BSS）和快速充电站（FCS）系统在重型卡车中的优缺点目前理解不足。本研究评估了这两种充电机制，旨在比较系统的效率并确定其最佳设计。开发了一个模型来解决BSS在充电网络中的规划和运营问题，考虑将站内电池作为各种服务的资产。我们评估了包括运输效率和电池利用效率在内的性能指标。我们的评估发现，BSS通过减少车辆停机时间显著提高了运输效率，但可能需要更多的电池。配备中型电池的BSS在时间和劳动力方面提高了运输效率。依赖FCS的卡车需要更大的电池来补偿延长的充电时间。为了理解这两种指标之间的权衡，我们在不同场景下进行了成本效益分析，涉及电池价格和劳动力成本的潜在变化。此外，BSS在通过能源 arbitrage 和电网辅助服务实现显著二氧化碳减排和增加盈利能力方面具有潜力。这些发现强调了将BSS整合到未来电动卡车充电网络中以及采用碳意识运营框架的重要性。
英文摘要：
The advantages and disadvantages of Battery Swapping Stations (BSS) for heavy-duty trucks are poorly understood, relative to Fast Charging Stations (FCS) systems. This study evaluates these two charging mechanisms for electric heavy-duty trucks, aiming to compare the systems' efficiency and identify their optimal design. A model was developed to address the planning and operation of BSS in a charging network, considering in-station batteries as assets for various services. We assess performance metrics including transportation efficiency and battery utilization efficiency. Our evaluation reveals that BSS significantly increased transportation efficiency by reducing vehicle downtime compared to fast charging, but may require more batteries. BSS with medium-sized batteries offers improved transportation efficiency in terms of time and labor. FCS-reliant trucks require larger batteries to compensate for extended charging times. To understand the trade-off between these two metrics, a cost-benefit analysis was performed under different scenarios involving potential shifts in battery prices and labor costs. Additionally, BSS shows potential for significant $\text{CO}_2$ emission reductions and increased profitability through energy arbitrage and grid ancillary services. These findings emphasize the importance of integrating BSS into future electric truck charging networks and adopting carbon-aware operational frameworks.
