State of charge (SOC) and state of health (SOH) are key issues for the application of batteries, especially the absorbent glass mat valve regulated lead-acid (AGM VRLA) type batteries used in the idle stop start systems (ISSs) that are popularly integrated into conventional engine-based vehicles. This is due to the fact that SOC and SOH estimation accuracy is crucial for optimizing battery ener...

The functionality and reliability of portable microelectronics systems is often limited by the ability of the power supply to provide a continuous source of energy. In modern portable applications, lithium ion, and lithium polymer batteries have become the choice energy system. The selection of these batteries is based on their high volumetric and gravimetric energy densities and their ability ...

In the process of battery system design and operation, accurate battery modelling is a key factor. Generally speaking, the electric characteristics of a given battery cell are necessary for a designer to build an equivalent circuit model. The equivalent circuit design entails the creation of both the sizing of components used in the circuit and the topology. So, it is very hard to build an accu...

State-of-charge (SOC) estimation of lithium-ion batteries (LIBs) is the basis other state estimations. However, its accuracy can be affected by many factors, such as temperature and ageing. To handle this bottleneck issue, we here propose a joint SOC-SOH method considering influence temperature. It combines Forgetting Factor Recursive Least Squares (FFRLS) algorithm, Total (TLS) Unscented Kalma...

In this paper, the recursive state-of-charge (SOC) estimation problem is investigated for Li-ion batteries. The uncertain parameters, which are used to account effects of changing temperatures, battery power and drift current sensors, considered in modelling process Moreover, uncorrelated/correlated noises also based on engineering practice. aim paper design a SOC scheme such that an upper boun...

In the operation of battery energy storage systems (BESSs) based on cascaded H-bridge (CHB) converters, it is desirable to balance state charge (SoC) among submodules (SMs) within each phase arm. However, there are constraints active power distribution SMs that intend SoC. For instance, SM in a practical system designed with specific rating and can be damaged if exceeded. Therefore, novel rule-...

The operating temperature of a battery energy storage system (BESS) has significant impact on performance, such as safety, state charge (SOC), and cycle life. For weather-resistant aluminum batteries (AlBs), the precision SOC is sensitive to variation, errors in AlBs may occur. In this study, combination experimental charge/discharge data 3D anisotropic homogeneous (Ani-hom) transient heat tran...

This article provides the dataset of both the LiFePO4 type lithium-ion battery (LIB) behavior and the Maxwell ultracapacitor behavior. The dynamic stress test (DST) condition and the urban dynamometer driving schedule (UDDS) condition were carried out to analyze the battery/ultracapacitor features. The datasets were achieved at room temperature, in August, 2016. The shared data contributes to c...
