The proliferation of electric vehicles (EVs) has posed significant challenges to the existing power grid infrastructure. It thus becomes of vital importance to efficiently manage the Electro-Mobility for large demand from EVs. Due to limited cruising range of EVs, vehicles have to make frequent stops for recharging, while long charging period is one major concern under plug-in charging. We herein leverage battery swapping (BS) technology to provide an alternative charging service, which substantially reduces the charging duration (from hours down to minutes). Concerning in practice that various battery is generally not compatible with each other, we thus introduce battery heterogeneity into the swapping service, concerning the case that different types of EVs co-exist. A battery heterogeneity-based swapping service framework is then proposed. Further with reservations for swapping service enabled, the demand load can be anticipated at BS stations as a guidance to alleviate service congestion. Therefore, potential hotspots can be avoided. Results show the performance gains under the proposed scheme by comparing to other benchmarks, in terms of service waiting time, etc. In particular, the diversity of battery stock across the network can be effectively managed.

在电池异构下实现高效的电池交换服务操作

电动汽车 (EV) 的激增给现有的电网基础设施带来了重大挑战。因此，对于电动汽车的大量需求，有效管理电动汽车变得至关重要。由于电动汽车的续航里程有限，车辆必须经常停下来充电，而充电时间长是插电式充电的一大问题。我们在此利用电池交换 (BS) 技术提供替代充电服务，从而大大缩短充电时间（从几小时缩短到几分钟）。考虑到在实践中各种电池通常彼此不兼容，因此我们将电池异构性引入到交换服务中，涉及不同类型的电动汽车共存的情况。然后提出了一种基于电池异质性的交换服务框架。此外，在启用交换服务预留的情况下，可以预期 BS 站的需求负载作为缓解服务拥塞的指导。因此，可以避免潜在的热点。结果表明，与其他基准相比，在服务等待时间等方面，所提出方案的性能提升。特别是，可以有效管理网络中电池库存的多样性。
