We're interested mainly in energy storage systems for automotive, grid, and off-grid applications. Lithium-ion batteries are a key area, but we also investigate lead-acid batteries, supercapacitors, flow batteries, and fuel cells. We collaborate widely with industry, and the spin-out company Brill Power was founded to exploit our research on smart battery systems.

Energy storage systems present many interesting engineering research challenges in terms of control, integration, degradation, thermal management and dynamic modelling. Systems engineering can make a huge difference to performance. For example, properties such as state of charge and state of health are not directly measurable, so we require validated models to estimate these. Performance also deteriorates as a result of various degradation mechanisms, and the complexity and interactions of these mechanisms makes it difficult to predict decreases in battery capacity and power capabilities accurately.
