Abstract Lithium‐ion batteries exhibit a well‐known trade‐off between energy and power, which is problematic for electric vehicles which require both high energy during discharge (high driving range) and high power during charge (fast‐charge

Lithium-ion batteries exhibit a dynamic voltage behaviour depending nonlinearly on current and state of charge. The modelling of lithium-ion batteries is therefore complicated and model parametrisation is often time demanding. Grey-box models combine
