Researchers Probe Grid Resilience Using Advanced Batteries

Isolated multichannel battery and cell voltage measuring circuit for use in series strings

A new university research partnership will show how advanced lead batteries can support electricity grid energy storage and plug-in to more renewable and other storage requirements for low carbon energy systems.  The project is being led by the University of Warwick and Loughborough University, supported by the Consortium for Battery Innovation (CBI).  Demand for batteries as a storage technology is steadily growing across the globe in order to support greater levels of grid flexibility, reliability and decarbonization as more renewables are integrated into the grid and in the face of extreme weather events. By developing more advanced levels of modelling and prediction of lead battery behaviour for utility grid storage, the r
