Abstract

Implementing battery electric buses (BEBs) in transit is considered a sustainable mobility means. However, various planning and operational challenges impede the full adoption of BEBs. Currently, BEB system optimization practice assumes that BEBs will deliver the same performance (battery capacity) over the entire service lifespan. However, BEBs' batteries will degrade over time, leading to a limited operating range. As such, the present study addresses the impact of BEBs' battery degradation on the BEB system infrastructure and component sizing optimization. The study develops a multi-stage optimization model to optimize BEB infrastructure and component sizing, considering battery degradation over the transit system service lifespan. The trade-off between adding charging infrastructure and/or battery replacement is assessed. The results show that adding more charging piles is more cost-effective than replacing the batteries for small hup-and-spoke transit networks. The results also show some insights to improve the adoption of BEBs in transit.

电池容量退化对优化beb运输系统配置的影响

在运输过程中实施电池电动公交车(beb)被认为是一种可持续的出行方式。然而，各种规划和操作挑战阻碍了beb的全面采用。目前，BEB系统优化实践假设BEB在整个使用寿命期间提供相同的性能(电池容量)。然而，beb的电池会随着时间的推移而退化，导致有限的工作范围。因此，本研究解决了BEB电池退化对BEB系统基础设施和组件尺寸优化的影响。该研究开发了一个多阶段优化模型，以优化BEB基础设施和组件尺寸，同时考虑到电池在运输系统使用寿命期间的退化。评估增加充电基础设施和/或更换电池之间的权衡。结果表明，增加充电桩比为小型轮辐式交通网络更换电池更具成本效益。研究结果还显示了一些改善交通中使用beb的见解。
