Low-complexity online estimation for LiFePO4 battery state of charge in electric vehicles

This paper proposes a low-complexity online state of charge estimation method for LiFePO4 battery in electrical vehicles. The proposed method is able to achieve accurate state of charge with less computational efforts in comparison with the nonlinear Kalman filters, and also can provide state of health information for battery management system. According to the error …

Advanced Management System for Li-Sulfur Batteries

As the trends in power generation and consumption are moving towards environmentally friendly solutions, batteries might play very important role in grid-oriented solutions (i.e. renewables smoothing), and especially in the transportation sector. Electrification of the transportation requires secondary batteries with high energy density, long lifetime and low cost. Currently, one of the most promising candidates …

Degradation of LFP-based Battery System used for Primary Frequency Regulation

Lithium-ion batteries have developed into a popular energy storage choice for a wide range of applications because of their superior characteristics in comparison to other energy storage technologies. Besides modelling the performance behaviour of lithium-ion batteries, it has become of huge interest to accurately estimate their degradation because of both economic and technical considerations. The …

Life time predictions of the lithium ion batteries in the Virtual Power Plant

Future large wind power plants (WPP) will be intended to function like conventional power plants seen from the transmission system point of view, by complying with grid codes and providing ancillary services. This can be possible by integration of battery energy storage systems (BESS) into the so called Virtual Power Plants (VPP). Relatively young storage …
