While previous studies focused on managing charging demand for private electric vehicles (EVs), we investigate ways of supporting the upgrade of an entire public urban electric taxi (ET) system. Concerning the coexistence of plugin charging stations (CSs) and battery swap stations (BSSs) in practice, it thus requires further efforts to design a holistic charging management especially for ETs. By jointly considering the combination of plug-in charging and battery swapping, a hybrid charging management framework is proposed in this paper. The proposed scheme is capable of guiding ETs to appropriate stations with time-varying requirements depending on how emergent the demand will be. Through the selection of battery charging/swap, the optimization goal is to reduce the trip delay of ET. Results under a Helsinki city scenario with realistic ETs and charging stations show the effectiveness of our enabling technology, in terms of minimized drivers’ trip duration, as well as charging performance gains at the ET and station sides.

通过电池充电和交换站的混合部署实现城市电动出租车的整体充电管理

虽然之前的研究侧重于管理私人电动汽车 (EV) 的充电需求，但我们研究了支持整个公共城市电动出租车 (ET) 系统升级的方法。考虑到插件充电站（CS）和电池交换站（BSS）在实践中的共存，因此需要进一步努力设计整体充电管理，尤其是针对 ET 的充电管理。本文综合考虑插电式充电和换电相结合，提出了一种混合充电管理框架。提议的方案能够根据需求的紧急程度将 ET 引导到具有时变要求的适当站点。通过电池充电/交换的选择，优化目标是减少ET的行程延迟。
