Electric vehicles (EVs) represent one of the solutions for reducing the carbon emissions worldwide. Even though EVs have recently gained more and more popularity, their adoption at a large scale is mainly prevented by several factors, such as range anxiety and battery degradation. The range of an EV is mainly limited by the energy density and specific energy of the battery, while the battery degradation...
Lithium-ion batteries are characterized by having very good performance in terms of efficiency, lifetime, and self-discharge, which allowed them to become the major player in the electric vehicle applications. However, they were not able to totally overcome the EV range anxiety. Thus, research is carried out nowadays to develop batteries with even higher gravimetric energy density, which should allow...
In order to analyze the dynamic behavior of a Lithium-ion (Li-ion) battery and to determine their suitability for various applications, battery models are needed. An equivalent electrical circuit model is the most common way of representing the behavior of a Li-ion battery. There are different circuit models proposed and various techniques for parameterization of these models available in literature...
With the popularity of Electrical Vehicles (EVs), Lithium-ion battery industry is also developing rapidly. To ensure the battery safety usage and reduce the average lifecycle cost, accurate State Of Charge (SOC) tracking algorithms for real-time implementation are required in different applications. Many different SOC estimation methods have been proposed in the literature. However, only few of them...
Lithium-ion (Li-ion) batteries are found nowadays not only in portable/consumer electronics but also in more power demanding applications, such as stationary renewable energy storage, automotive and back-up power supply, because of their superior characteristics in comparison to other energy storage technologies. Nevertheless, prior to be used in any of the aforementioned application, a Li-ion battery...
Lithium-Sulfur (Li-S) batteries are an emerging energy storage technology, which draw interest due to its high theoretical specific capacity (approx. 1675 Ah/kg) and theoretical energy density of almost 2600 Wh/kg. In order to analyse their dynamic behaviour and to determine their suitability for various commercial applications, battery performance models are needed. The development of such models...
Modern lithium-ion batteries, like LiMO2/Li4Ti5O12 chemistry, are having very high power capability, which drives the need for precise thermal modelling of the battery. Battery thermal models are required to avoid possible safety issues (thermal runaways, high-temperature gradients) but also for the optimal battery pack design and for predicting battery electrical performance during operation (especially...
The impedance represents one of the most important performance parameters of the Lithium-ion batteries since it used for power capability calculations, battery pack and system design, cooling system design and also for state-of-health estimation. In the literature, different approaches are presented for measuring the impedance of Lithium-ion batteries and electrochemical impedance spectroscopy and...
