“…A series of simulations with different ECM parameter definitions (Chen's definition [17], a 5 th order polynomial definition and a look-up table definition) were carried out. In order to better evaluate the results, the circuit parameters were estimated from [14], in which the parameters were extracted from a 3.4 Ah Li-S battery from OXIS Energy at the temperature of 30 ºC and compared with the results from Stroe et al [13].…”

Lithium-sulfur batteries appear to be an exciting technology for energy storage due to their many advantageous properties. Due to its low weight and high energy, this technology could be used in aviation, aerospace or in heavy electric vehicles or even for mobile applications. This article investigates possible approaches for modelling of lithium-sulfur batteries. A new method using Ansys Fluent add-on Multi-Scale Multi-Domain battery module, originally designed for lithium-ion batteries, is presented. Battery characteristics are described through an equivalent circuit model, which can capture its complex characteristics. The results suggest that the built-in Ansys Fluent model can be successfully extended for 3D modelling of lithium-sulfur batteries. The critical point of the simulation is the precise definition of equivalent circuit model parameters.

“…To ensure safe and secure energy source, military bases around the world are developing stationary battery storage systems coupled with renewable energy sources slightly varied but generally consisted of a serial resistor and from one to four R-C elements [9,10,12,13]. All of these studies used a custom 0D models.…”

“…It is needed to use the accurate parameterization of the elements of the ECN technique to achieve reliable results. The widely used techniques for the ECN elements parametrization are pulse-based methods [31,32] and the electrochemical impedance spectroscopy (EIS) [22,[33][34][35][36][37][38].…”

The stationary photovoltaic array can be used to charge the different vehicle batteries and, in parallel, be used as a power source for the utility grid or standalone devices placed such as in campers. The main objective of the study was to compare chosen electrical characteristics of two assemblies with each containing the same PV array, boost converter and inverter, and a different battery, such as the Li-S one and the Li-ion one, respectively. Differences occurring during modelling of Li-ion and Li-S batteries were discussed. The model of the chosen photovoltaic array was used during analysis. The models based on electrical equivalent circuits for Li-ion battery and of Li-S battery were utilized during calculations. The models of the boost converter and boost inverter of known topology parameters were utilized during simulations. In the chosen performances (courses of voltages and currents versus time) obtained from the simulation of the sets composed of the Li-S battery cooperating with the boost inverter or the boost converter, only small differences or no differences occurred when compared to the case of the Li-ion battery.

“…It is essential to accurately parametrize the different elements in the ECN model to obtain reliable results. The extensively used methods to parametrize the ECN elements are current pulse-based methods (Stroe et al, 2016;Wagner et al, 2016) and the electrochemical impedance spectroscopy (EIS) (Daowd et al, 2010;Hentunen et al, 2014;Hu et al, 2011;Lin et al, 2014;Sun et al, 2009;Thanagasundram et al, 2012;Stroe et al, 2017). Another difference between Li-ion and Li-S is that the last one, the voltage profile is substantially distinct between charge and discharge.…”

The market share in electric vehicles (EV) is increasing. This trend is likely to continue due to the increased interest in reducing CO emissions. The electric vehicle market evolution depends principally on the evolution of batteries capacity. As a consequence, automobile manufacturers focus their efforts on launching in the market EVs capable to compete with internal combustion engine vehicles (ICEV) in both performance and economic aspects. Although EVs are suitable for the day-to-day needs of the typical urban driver, their range is still lower than ICEV, because batteries are not able to store and supply enough energy to the vehicle and provide the same autonomy as ICEV. EV use mostly Lithium-ion (Li-ion) batteries but this technology is reaching its theoretical limit (200-250 Wh/kg). Although the research to improve Li-ion batteries is very active, other researches began to investigate alternative electrochemical energy storage systems with higher energy density. At present, the most promising technology is the Lithium-Sulphur (Li-S) battery. This paper presents a review of the state of art of Li-Sulphur battery on EVs compared to Li-ion ones, considering technical, modelling, environmental and economic aspects with the aim of depicting the challenges this technology has to overcome to substitute Li-ion in the near future. This study shows how the main drawbacks for Li-S concern are durability, self-discharge and battery modelling. However, from an environmental and economic point of view, Li-S technology presents many advantages over Li-ion.
