A Mobile Battery Swapping Service for Electric Vehicles Based on a Battery Swapping Van

Abstract

This paper presents a novel approach for providing a mobile battery swapping service for electric vehicles (EVs) that is provided by a mobile battery swapping van. This battery swapping van can carry many fully charged batteries and drive up to an EV to swap a battery within a few minutes. First, a reasonable EV battery swapping architecture based on a battery swapping van is established in this paper. The function and role of each participant and the relationships between each participant are determined, especially their changes compared with the battery charging service. Second, the battery swapping service is described, including the service request priority and service request queuing model. To provide the battery swapping service efficiently and effectively, the battery swapping service request scheduling is analyzed well, and a minimum waiting time based on priority and satisfaction scheduling strategy (MWT-PS) is proposed. Finally, the battery swapping service is simulated, and the performance of MWT-PS is evaluated in simulation scenarios. The simulation results show that this novel approach can be used as a reference for a future system that provides reasonable and satisfying battery swapping service for EVs.

Small-Signal Modeling and Analysis for a Wirelessly Distributed and Enabled Battery Energy Storage System of Electric Vehicles

“…Battery energy storage systems (BESS) have been widely used in various applications, such as electric vehicles (EVs), consumer electronics, medical devices, smart grid, energy backup in data centers, and among others [1][2][3][4][5][6][7][8][9][10]. For EV applications, what is referred to be as "range anxiety" is one of the major reasons that prohibit or slows down the adoption of EVs [9][10][11][12][13][14].…”

Control Scheme and Power Electronics Architecture for a Wirelessly Distributed and Enabled Battery Energy Storage System

“…The limited driving range and the needed recharging time of the lithium-ion (Li-Ion) battery pack is one of the major/top reasons/barriers slowing down the adoption of electric vehicles (EVs) [1][2][3][4][5][6][7][8]. This is as a result of what is referred to by "Range Anxiety" [1,[3][4][5]. The uncertainty and worry about if the battery of an EV has sufficient energy to reach a destination (especially for long range drives), thinking about when there is a need to recharge the battery, and/or how long is the time needed to recharge an EV battery cause anxiety.…”

“…(3) Adopt battery swapping concept. While battery swapping concept is about a century old, there have been increased consideration of the concept and related developments [4,5,15,16]. The drawback of existing battery swapping concepts are such as: (a) the weight of the battery necessitate specialized equipment and installation methods to realize swapping which needs to be available/accessible in many locations; (b) the involved electrical and mechanical connections require trained personnel in addition to specialized equipment to perform the swapping; (c) there might be safety and reliability risks each time the battery is swapped if not done appropriately/correctly; and (d) swapping a battery with large size and heavy weight might require longer time than refueling a vehicle with gasoline.…”

Study on EV Charging Peak Reduction with V2G Utilizing Idle Charging Stations: The Jeju Island Case

“…Battery swapping is the most commonly used method for buses to shorten the charging time, as buses have large battery capacity compared to that of passenger vehicles [42,43]. For such vehicles, battery charging can be performed with slow charging or charging in advance at night to reduce electricity costs.…”
