Abstract The health status of lithium-ion batteries and the acquisition internal information for battery designs predictions are great significance. Electrochemical impedance spectroscopy (EIS) is a measurement method that has received more attention in research on batteries’ performance. In this paper, three kinds made different materials were studied to measure at temperatures. An equivalent ...

With the widespread application of electric vehicles, study power lithium-ion battery (LIB) has broad prospects and great academic significance. The state charge (SOC) is one key parts in management system (BMS), which used to provide guarantee for safe efficient operation LIB. To obtain reliable SOC estimation result under influence simple model measurement noise, a novel method with adaptive ...

Summary The state‐of‐charge (SOC) of the battery is most critical parameter for an electric vehicle (EV) dashboard. Generally, Coulomb counting (CC) method used SOC estimation, but conventional CC has some errors due to initial determination. This work uses modeling and estimation a lithium‐iron‐phosphate (LFP) determine SOC. equivalent circuit models (ECMs) have been parameters by least‐square...

The service life of Lithium-ion batteries disposed from electric vehicles, with an approximate remaining capacity 75–80%, can be prolonged their adoption in less demanding second applications such as buildings. A photovoltaic energy generation system integrated a battery storage device is modelled mathematically to assess the design’s technical characteristics. reviewed studies literature assum...

in this paper, a neural network model reference adaptive system speed observer is designed, which can be used in speed control of linear induction motors (lims). dynamical equations of lim have been considered accurate. in other words, the end effect and the electrical losses of the motor have been included in the motor equivalent circuit. then equations of the reference model and adaptive mode...

in the present study, a model of a large lithium polymer (li-po) battery for use in the simulation of hybrid electric vehicles (hevs) is developed. to attain this goal, an equivalent circuit (ec) consisting of a series resistor and two rc parallel networks is considered. the accuracy and the response time of the model for use in an hev simulator are studied. the battery parameters identificatio...

a mathematical modelling for more-winding single-phase transformer is presented. the incidence matrix-which gives the informations about the connection of the ends of the windings between the nodes-is multiplied leftside and rightside with the inverse of the inductance matrix of the more winding transformer. the result is a matrix which gives the relationship between nodes potentials and nodes ...

Performing fast and accurate methods for modeling the electrical machines has been the subject of several studies and many authors proposed different procedures to attain this aim. Beside the accuracy, the speed of the method is of great concern. On the other hand, the capability of the method to be changed according to the need is another important issue. Finite Element method provides relativ...

Snapback breakdown is the second order effect of avalanche breakdown in a device. Snapback occur when the excess supply voltage and high currents created flow through the device and become unstable. These two breakdowns are used to explain the concept of Vertical Impact Ionization MOSFET (IMOS) in its Equivalent Circuit Model. The equivalent circuit model design consists of MOS transistors that...

This article presents a numerical study of the electroporation process of spherical cells suspended in an electrolyte solution, using the equivalent circuit method (ECM) for field calculation proposed by Ramos et al. A model for the electric conductance of the cell membrane derived from the analytical and experimental results obtained by Glaser et al. for planar lipidic membranes was applied. T...
