Abstract The extensive application of Sodium-Nickel Chloride (Na-NiCl2) secondary batteries in electric and hybrid vehicles, in which the safety requirements are more restrictive than these of stationary storage applications, depicts the Na-NiCl2 technology as perfectly suitable for the stationary storage applications. The risk of fire is negligible because of the intrinsic safety of the cell chemical reactions, related to the sodium-tetrachloroaluminate (NaAlCl4) content into the cell, which acts as a secondary electrolyte (the primary one being the ceramic β″ -alumina as common for Na-Beta batteries). The 3 h rate discharge time makes this technology very attractive for load levelling, voltage regulation, time shifting and the power fluctuation mitigation of the renewable energy sources in both HV and EHV networks. © 2015 Elsevier B.V.

The purpose of this paper is to present a reliable modelling of sodium-chloride battery in Simulink environment in order to have a powerful tool which is able to foresee the battery behaviour in both discharge and charge operations. The model is based on a wide set of measures (e.g. discharge and charge resistance for different depth of discharge and current rates, etc.). A comparison between the model results and real battery measures, in the same conditions, has been presented. © 2015 AEIT. Source

The purpose of this paper is presenting a reliable modelling of sodium-nickel chloride battery in order to have a powerful tool which is able to foresee the steady state battery behaviour in both discharge and charge operations. The proposed modelling approach allows representing both constant current operations and variable charge or variable discharge current ones, but it does not allow passing instantaneously from one battery mode to another one. This method is based on experimental measures. All the main modelling steps are described and a comparison between the model results and real battery measures, with the same conditions, is presented. The very good agreement between measures and model confirms the robustness of the approach for steady state applications. The paper proposes to adopt a set of standard battery measures from which it is possible to infer a simple but very precise modelling structure. © 2016 Elsevier Ltd. Source
