It’s become part of everyday life. “Most of us plug in our laptops or phones to recharge at night without really thinking about it,” says Serena Corr, Chair in Functional Materials and Professor in Chemical and Biological Engineering at the University of Sheffield, “but what’s happening during charge and discharge is a highly complex process …

TheDrive: “A thread on popular Tesla forum Tesla Motors Club has begun to track battery degradation over time with the use of community-sourced and tracked data. Using a scatter plot, the overwhelming worldwide response to the request for data was able to establish a clear trend line. In 270,000 kilometers (168,000 miles), the average battery degraded less …

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 …

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 …

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 …
