A general electric model of sodium-nickel chloride battery

The paper presents the analysis of Sodium Nickel chloride batteries in transient operation, and proposes a very simple but quite precise model to represent both the transient and steady battery behaviours. The used modelling approach is based on steady state experimental measures. Sodium Nickel chloride batteries are one of the most promising technologies for electrical energy stationary storage in the high voltage network. Hence, the main purpose of this model is to foresee the battery voltage during the most important network services, which require very fast transition from the battery charge operation to the discharge one. In order to validate the model, several comparisons between experimental measures and model results are shown.
