The following document aims to show the initials steps for the design of a battery system based on sodium and metal halydes chemistry.

Before starting the design of the BCS (Battery Control System), a complete comprehension of the battery behaviour is necessary to decide on the proper sizing of the components and the best algorithms for processing.

A brief overview on the state of art of these batteries and on battery system design will be presented to give the reader a proper background on the arguments.
Than the chemical behaviour of a single cell is studied to understand the important parameters that have to be taken into consideration to realize simplier models that can be used on the BCS to estimate the state of the battery.
Two different simplified models will be presented obtained from two different approach to the problem.
The last chapter is dedicated to the thermal modelization and aims to provide a good estimation of the temperature distribution inside the battery.
After completing the modelling part, the initial steps for the design of an innovative BCS are presented.

The results obtained are preliminary for future work on a complete design of the system.
