This paper aims to evaluate the AC loss of a High Temperature Superconducting (HTS) cable with respect twisting angle while considering mechanical constraints in an iterative approach. A 1km 22.9kV HTS was selected this study assess impact alterations. The electromagnetic behavior modeled using Equivalent Circuit Model (ECM). After implementation model MATLAB/SIMULINK, series simulations were p...

Traditional equivalent circuit models (ECMs) have difficulties in estimating battery internal states due to the lack of relevant physics, such as lithium diffusion active particles. Here we configure a network describe and define it new high-level element called diffusion-aware voltage source. The representation is proven discretized equation. source gives electrode potential function surface c...

Abstract: Parameterization of battery dynamics based on terminal operating data is a main concern in engineering applications of batteries. The key technology is designing an adequate test procedure and a data processing procedure to excite different inner dynamics and then estimate the parameters of a corresponding equivalent circuit model (ECM). This paper proposes a parameter identification ...

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...

This paper focuses on state of charge (SOC) estimation for the battery packs of electric vehicles (EVs). By modeling a battery based on the equivalent circuit model (ECM), the adaptive extended Kalman filter (AEKF) method can be applied to estimate the battery cell SOC. By adaptively setting different weighed coefficients, a battery pack SOC estimation algorithm is established based on the sing...
