<p>Provided are a molten salt battery device capable of controlling the temperature of its molten salt batteries evenly and being further cooled easily; and a method for controlling the temperature of a molten salt battery. In the molten salt battery device, molten salt batteries 1 are arranged in a container 2 to cause a space to be present around the molten salt batteries 1, and a heating medium 3 is filled into the space around the molten salt batteries 1. While an electrothermal heater 51 is used to control the temperature of the heating medium 3 through a temperature controlling section 52, the heating medium 3 is caused to flow. Between the flowing heating medium 3 and the molten salt batteries 1, heat is exchanged, whereby the molten salt battery device controls the temperature of the molten salt batteries 1. Since the molten salt batteries 1 attain the heat exchange with the heating medium 3, which surrounds the batteries, the internal temperature thereof is evenly controlled. Moreover, the molten salt battery device makes it possible to lower the temperature of the heating medium 3 to cool the molten salt batteries 1 easily.</p> |
