ABSTRACT:
A sodium sulphur battery formed of a plurality of modules each containing a cell or cells has a passage through each module for a heating and/or cooling fluid and thermostatically controlled valve means for controlling the flow of fluid through this passage which valve means is open at temperatures above a predetermined temperature, e.g. 370.degree. C. for passage of a coolant fluid and is also open at temperatures below another predetermined temperature, e.g. 300.degree. C. for passage of a heating fluid. The valve is preferably gradually closed and opened between these tempteratures. Each valve is controlled in accordance with the temperature of the associated module.
