The primary obstacle to unlocking large-scale battery digital twins

Large-scale energy storage systems are critical on the road to electrifying and decarbonizing the grid's energy. However, these systems consist of numerous individual cells and various ancillary systems, where monitoring and controlling cell-level behavior become challenging due to potential cell-to-cell variations. In a recent issue of Applied Energy, Reniers and Howey built a digital twin for a 1 MWh grid battery system consisting of 18,900 cells and conducted a 10-year simulation, demonstrating the significance of battery system monitoring and control in mitigating cell-to-cell variations over the battery's lifespan.
