Optimal configuration of EV battery swapping station considering service availability

Abstract

Battery swapping becomes one of the most important ways to supply the energy for electric vehicles (EVs), since it takes a short time to recharge and is convenient in managing. It leads to growing popularity of the EVs to develop the battery swapping station (BSS). This paper investigates the optimization of the number of EV battery (EVB) packs and the chargers of the station. The structure of the station system and the operation strategy of "charging immediately after swapping" is first talked about. Then, the number of EVB packs in different states is analyzed based on the aforementioned strategy. We build a mathematical model which has the objective of uniform annual value of the facilities' cost, and restrictions of the size of the station and the demand of availability of battery swapping service per day (ABSSD). The mathematical model is solved with DE algorithm. The optimization method is configured and proved to be rational by results of a case analyzed. The research provides support for configuration plan of BSS.

An Optimization Model for Electric Motorcycle Battery Swapping Station in Indonesia: A Case Study

“…The first study that determined the initial battery stock quantity at BSS was carried out by some researchers [12], focusing on electric vehicle in San Francisco. In [13], the differential evolution (DE) method was utilized to determine the optimal battery stock quantity to meet the daily battery swapping demand at BSS in Beijing. [6] optimized the utilization of available batteries at BSS and minimized battery costs resulting from different charging methods in Hong Kong, employing the genetic algorithm (GA) approach.…”

“…The adoption of optimization models in this research uses the reference model from [13] which has been modified with the formulation of mathematical equations…”

“…Optimal distribution of EV penetration as well routing strategies of BSS networks is also studied in some works [24,25]. Traces of research efforts associated with efficient charging scheduling of EV batteries in battery swap stations have also been found as in [26,27]. But a unifying framework that exhaustively encompasses all the issues that may arise while attempting to set up a viable infrastructure considering whole of abovementioned attributes is the need of tomorrow.…”

Autonomous Battery Swapping System and Methodologies of Electric Vehicles

“…A RES integrated with the BSS is reviewed in [12], and the interaction and power exchange between different components of the BShN and the power grid is also detailed in [12]. An optimal configuration of a BSS in terms of the number of chargers and battery packs is discussed in [13]. Converters and charger topologies for enabling grid-to-vehicle (G2V) and vehicle-to-grid (V2G) power exchanges are discussed in detail in [14].…”
