があった。2. Description of the Related Art NaS batteries are operated at a high temperature of 300 to 350 ° C., and are therefore housed inside a vacuum insulated container having double walls for the purpose of preventing a decrease in thermal efficiency due to heat loss. However, as schematically shown in FIG. 5, when the NaS battery is in an energized state, heat is generated by Joule heat and the temperature inside the vacuum insulated container rises. The temperature drops. For this reason, conventionally, the heat insulating property of the vacuum heat insulating container is set gently so as not to reach the dangerous temperature even when the temperature of the NaS battery rises due to energization. However, as a result of reducing the heat insulating properties of the vacuum heat insulating container in this way, a large amount of electric power for heat retention is required during the idle period, and the operating cost is disadvantageously increased.

Reference numeral 1 denotes a plurality of vacuum insulated containers having inner and outer double walls accommodating a NaS battery (not shown) therein. The groups to be paused are shown. Each vacuum insulated container 1
The space between the double wall surfaces is connected to the chamber 4 via the conduit 2 and the solenoid valve 3. The chamber 4 is connected to a vacuum pump 6 via an electromagnetic valve 5. Therefore, if the inside of the chamber 4 is depressurized by the vacuum pump 6 and the solenoid valve 3 is opened, the pressure between the double wall surfaces of each vacuum insulated container 1 can be reduced through the pipe 2 to increase the degree of vacuum.

This branch pipe is for sucking outside air and reducing the degree of vacuum (increasing the pressure). First, the solenoid valve 9 is opened to bring the pressure inside the second chamber 8 close to the atmospheric pressure. When the solenoid valve 7 is opened, the pressure between the double wall surfaces of each vacuum insulated container 1 can be increased through the conduit 2 to reduce the degree of vacuum. The chamber 4 and the second chamber 8 are convenient for finely adjusting the pressure, but the pipe 2 is connected directly to the vacuum pump 6 or the outside air is directly sucked into the pipe 2. No problem.

る。The electromagnetic valves 3, 5, 7, 9 and the vacuum pump 6 are automatically operated by a control device linked to the temperature measuring device of the NaS battery. is there. First, when the NaS battery is in an energized state, the temperature of the NaS battery itself tends to increase due to Joule heat as shown in the upper part of FIG. 2, and the temperature measuring device attached to the NaS battery detects this. The detected temperature is
When Ru exceeds the fixed temperature, the control device opens the pulsed to indicate the solenoid valve 7 in the second row of FIG. 2, raising the pressure between the double walls of each of the vacuum insulated container 1. As a result, the heat loss of each vacuum insulated container 1 increases as shown in the third row of FIG. 2 to dissipate the internal heat. As shown, it is kept almost constant. This prevents the NaS battery from reaching a dangerous temperature.

Since the temperature of the battery tends to decrease, it is necessary to increase the degree of vacuum (decrease the pressure) of each vacuum insulated container 1 to reduce the heat loss, contrary to the above. The detected temperature is
When the temperature falls below a certain temperature, the solenoid valve 3 is opened, and the pressure between the double wall surfaces of each vacuum insulated container 1 is reduced through the pipe 2. As a result, the amount of heat dissipated in the vacuum insulated container 1 is reduced, so that even in the case of a long-term shutdown, less power is required for keeping heat than before.
