SOH estimation of EV and HEV lithium-ion battery applications

Skripko L.

This paper reports some results relating to a new method of state-of-health (SOH) estimation for battery-based systems of electro- and hybrid vehicles. Some main challenges were addressed for the accurate estimation of SOH at runtime. Relevance of the problem raised is the need to control the SOH of batteries in order to prevent the experiment results show the feasibility and effectiveness of the algorithm for LFP 20Ah cells.

Selection and optimization of design parameters for reversible reciprocating electric machine

Safin A., Ivshin I., Kopylov A., Gracheva E., Tsvetkov A.

The article presents the technique of design parameters choice and substantiation for a reversible electric machine with reciprocating motion in the engine and generator mode. The aim of the study is to calculate the rational parameters of an electric machine to ensure maximum energy efficiency taking into account the given conditions. The concept of parallel simulation (Co-Simulation) is proposed. The concept is based on the data exchange between the programs MATLAB Simulink, CATIA V5 and a special program. The concept makes it possible to exchange the data between the marked programs to improve the efficiency, accuracy, simulation and optimization of the parts structural dimensions. These values are placed in a 3D model of a linear electric machine in CAD CATIA V5 for later kinematic and strength calculation. The modeling data in the software package MATLAB Simulink based on the programs written in MATLAB are transferred to the project table Excel, which is synchronized with the CAD CATIA V5. CATIA V5 develops 3D models of an electric machine stator and translator. The developed method allows to determine the rational parameters of an electrical machine during a design stage, followed by an adjustment during the manufacture of an experimental sample.

Keywords: reciprocating electric machine, simulation, three-dimensional modeling, optimization, energy efficiency.

Сalculationof short-circuit current in alternating current traction catenary accounting for external electric power supply system

German L., Subhanverdiev K.

It is emphasized in the study that, under assumptions adopted in the industry standard for calculation of short-circuit currents, determination of resistance of external power supply system based on the short-circuit current power on substation entry terminals allows for a considerable systematic error. To determine this systematic error, short-circuit current calculations were performed for two power supply layouts of VL-110kV and VL-220kV HV lines, one employing the common assumption and the other based on actual external power supply circuits. Comparative analysis of results produced under the two approaches yielded the error values across the short-circuit power range on the 110/220 kV traction substation busbars. Experimental verification was carried out to confirm the short-circuit current calculation error in the traction catenary.

Keywords: external electric power supply system, traction network, calculation error, short-circuit currents, traction substation, alternating current.
