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 …

A Stanford University-led team recently published research detailing how particles charge and discharge at the nanoscale, giving new insight into the fundamental functioning of batteries and opening doors for the development of better rechargeables. This new insight into the electrochemical action that powers Li-ion batteries provides powerful knowledge into the building blocks of batteries. “It …

Network Rail has started trials of its first battery-powered train on a test track in Derby, UK, after completing the retrofitting of the unit. The on-track trials will culminate into a series of high-speed tests at the Rail Innovation and Development Centre (RIDC) in Nottinghamshire at the end of the year. The project was co-funded …

The electric vehicle appears to be the new frontiers in lithium batteries. Distinctly different from mass produced microelectronics, it requires higher energy density as well as improved power performance requirements. Especially, charge/discharge rates during startup from standstill, deceleration, emergency charging, etc. provide unique challenges. To this end, new chemistries and new material with morphologies like …

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 …

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 …
