A novel online adaptive state of charge (SOC) estimation method is proposed, aiming to characterize the capacity all connected cells in lithium-ion battery (LIB) packs. This realized using extended Kalman filter (EKF) combined with Ampere-hour (Ah) integration and open circuit voltage (OCV) methods, which time-scale implementation designed reduce computational cost accommodate uncertain or time-varying parameters. The working principle power LIBs their basic characteristics are analysed by...
Usually, uranyl (UO22+) is competitively adsorbed by coexisting potentially toxic metal ions (Xn+: Rb+, Sr2+, Cr3+, Mn2+, Ni2+, Zn2+, Cd2+) that limit the adsorbent application. Here, core–shell MFe2O4–TiO2 (M = Mn, Fe, Zn, Co, or Ni) nanoparticles were synthesized on K-montmorillonite (MMT) edge sites and assessed as new selective adsorbents. The results revealed UO22+ Xn+ simultaneously TiO2(101) surfaces, MFe2O4(111)–TiO2(101)/MMT(100)–MFe2O4(111) interfaces, MMT inner layers....
[Purpose] The security guaranteeing method for the lithium-ion battery is studied and a novel state of charge (SOC) estimation proposed based on Kalman filtering (KF) thought, aiming to guarantee its safety in power supply application electric vehicles (EVs). In this study, there are several parts that have been realize protection during whole life period. Firstly, core parameters working methods analyzed. Secondly, estimated by integrated methods. Then, model designed realized principle. At...
Given the extensive use of antibiotics at present, identification and production quality monitoring are high importance. However, conventional antibiotic methods have a low sensitivity long detection time. Here, we propose an method that combines terahertz (THz) spectroscopy chemometric technology. THz time-domain (THz-TDS) was performed for sixteen types antibiotics, including β -lactam, cephalosporins, macrolides, tetracyclines. The absorption spectra within frequency range 0.2–1.5 were...
Due to the instability of α type HMX at low concentrations, it belongs impurity crystal form. To ensure functional effectiveness, operational reliability and management safety HMX, is necessary quantify content unstable α-HMX form in composite explosive. In this study, low-concentration quantitatively analyzed a mixture α- β-HMX. First, terahertz time-domain spectroscopy (THz-TDS) used obtain absorption spectrum α/β-HMX element frequency range 0.2-2.0 THz, characteristic selected. The...
Cocrystals represent an effective method to manipulate the physicochemical properties of materials at a molecular level. However, understanding relationship between their complex crystal structures and macroscopic is challenge. In this paper, by using terahertz (THz) spectroscopy characterize non-covalent interactions within crystals, THz vibrational spectra CL-20/MTNP cocrystal are studied. Firstly, CL-20, MTNP, measured room temperature. Both absorption positions intensities cocrystals...
In recent years, the wind farm has developed rapidly in northern China. However, construction and operation of directly or indirectly result change soil structure, thus affecting regional ecological environment. According to characteristics turbine engineering, disturbance area can be divided into core disturbed zone, secondary zone indirect zone. A field study was conducted investigate physical chemical properties surface different zones. The results show that: (1) compaction, bulk density...
A systematic research on the electron deposition process in JAEA 10 ion source is carried out by using a particle-in-cell/Monte Carlo collision simulation, which based full three-dimensional self-developed code. Two parts are studied. One space and energy distribution of fast slow electrons, other vibration excitation collisions between electrons hydrogen moleculars. The results show that inhomogeneity comes from Y direction drift (Te ≥ 25 eV) due to action magnetic fields. This also...
The present paper used synthesized data from the experiment samples to replace partial basic experiments, and increased training amount 14 27. In principal component analysis (PCA), dimensionality of multivariate was reduced n components almost all information kept. PCA network's input nodes 60 3 simplify neural structure. Finally, back-propagation network train predict these samples. It had 27 samples, layer three nodes, hidden two output nodes. Its excitation function is variable learning...
The SOC (State Of Charge) estimation is a core aspect for the associated BMS (Battery Management System) equipment of lithium battery pack, in which KF (Kalman Filter) -based methods have been extensively used but suffers from linearization accuracy drawbacks. A novel UKF (Unscented Kalman method model proposed treatment not required and fewer Sigma data points are used, reducing computational requirement estimation. improves covariance properties performance has validated by experimental...
An Unattended Detection method for monitoring the CO <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> concentration in soil respiration is described.
