Nowadays, lithium-ion battery is the focus of research in the new energy industry, and SOC (State of Charge) is one of the key studies in the study of lithium-ion battery, the estimation and calculation of SOC is directly related to the efficiency and safety of the use of lithium-ion battery, a good SOC estimation and calculation method can make the work of lithium-ion battery more secure, and ...
A second-order discrete-time sliding mode observer (DSMO)-based method is proposed to estimate the state of charge (SOC) of a Li-ion battery. Unlike the first-order sliding mode approach, the proposed method eliminates the chattering phenomenon in SOC estimation. Further, a battery model with a dynamic resistance is also proposed to improve the accuracy of the battery model. Similar to actual b...
The performance of pure electric and hybrid electric vehicles highly depends on accurate and reliable knowledge of internal battery parameters. Specifically, parameters such as the state-of-charge (SOC), state-of-health (SOH) and state-of-power (SOP) are of particular interest. This paper presents new algorithms for estimating these three key parameters using an OCV-R-RC electrical equivalent c...
Although there is no experimental data available for antihydrogen formation following antiprotons impact on positroium atoms, as a charge transfer reaction, at incident energies which are suitable for antimatter high-precision spectroscopic studies, measurements were carried out for its charge-conjugate reaction i. e. hydrogen formation, by protons impact on positronium. In this study, a two-st...
this study is an outlook of iranians religious practices and customs in eras such as nasser one. it attempts to answer the main question, "religious practices and ceremonies in the society during naseri ruling" and other subsidiary questions with scientific and historical theories. iran was a traditional and religious community . people abided by their religious practices and duties within reli...
Accurate state of charge (SOC) is great significant for lithium-ion battery to maximize its performance and prevent it from overcharging or overdischarging. This paper presents an ensemble Kalman filter- (EnKF-) based SOC estimation algorithm battery. Firstly, the modeled by first-order RC equivalent circuit, multi-innovation least square (MILS) used perform online parameter identification mode...
Original scientific paper The fast and accurate estimation of state of charge (SOC) of lithium-ion battery is one of the key technologies of battery management system. In view of this nonlinear dynamic system of lithium battery, through the test and analysis of lithium-ion battery hysteresis characteristics, the second-order RC hysteresis model is established, and the cubature Kalman filter alg...
The capacity (state of charge/SoC) and voltage of lithium-ion batteries are of prime importance in electric vehicles, so their condition-monitoring techniques are extensively studied. This paper focuses on the application of the grey system theory to the parameters analyzing and predicting behavior during the discharge/charge cycles of the battery. Firstly, Grey Relation Analysis (GRA) is appli...
utopia has, for four centuries, accompanied that hope of progress and that striving for betterment. it now straggles against a widespread sense that this has been an illusion, or an impossible dream. the utopian idea can never entirely disappear, but utopia as a form of the social imagination has clearly weakened. if it cannot instill its vision in the public consciousness, the consequences...
This paper focuses on the state of charge estimation (SOC) for battery Li-ion. By modeling a based equivalent circuit model, extended Kalman filter approach can be applied to estimate SOC. An electrical model is developed in Matlab, Where structure detailed by equations and blocks. The has been validated from experiment results. comparison shows good agreement predicting voltage, SOC performs b...
