Battery energy storage has become an important part of modern power systems. As such, its operation model needs to be integrated in the state-of-the-art market clearing, system operation, and investment models. However, models that commonly represent operation of a large-scale battery energy storage might be inaccurate as they ignore multiple factors:

1. the dependence of the charging ability on the state-of-energy,  
2. dependence of the efficiency on the charging/discharging speed,
3. dependence of the voltage rebound effect upon fast discharging.

Such detailed models already exist but are way too complex for power system applications. The talk will present laboratory experiments performed on lithium-ion battery cells and propose new linear models that accurately describe the reactions within the battery.
