摘要： PROBLEM TO BE SOLVED: To uniformize temperature distribution among a plurality of cells arranged flat by using a vacuum heat insulating container having double walls or a multiple walls as a heat insulating container, and making the vacuum inside of an upper wall and/or inside a lower wall lower than that inside a side wall to adjust heat conductivity. SOLUTION: A vacuum heat insulating container in which a heat insulating material is filled in the gap of double metal walls and the gap is evacuated is used as a heat insulating container 2. The heat insulating container 2 has such structure that a box-shaped container main body constituted with a side wall 21 and a lower wall 22 is covered with a box-shaped cover 24 constituting an upper wall 23. The vacuum inside of a lower wall 22 and/or inside an upper wall 23 is set lower than that inside a side wall 21 so that the heat conductivity of the lower wall 2 and/or the upper wall 23 is made larger than the side wall 21. The vacuum on inside of the upper wall 23 is controlled according to the temperature of a high temperature sodium secondary battery by using a vacuum pump 7 or a leak valve 8.

摘要： PROBLEM TO BE SOLVED: To reduce a necessary energy for keeping the temperature of module to attain a high efficiency by controlling the heat conductivity of heat insulation vessel at the time of charging or waiting after a first discharge, and substantially making the temperature of battery before the start of secondary discharge corresponding to the temperature before the start of the first discharge. SOLUTION: In repeating 8-hrs discharging, 10-hrs charging and 6-hrs waiting, 8-hrs rating discharging is carried out under a high vacuum condition where the pressure of a cover 24 of a heat insulation vessel 2 is at about 0.001 atmosphere to reduce the heat conductivity of the vessel 2. Sucessively, a leak valve 8 is controlled to reduce the vacuum condition in the pressure of the cover 24 to about 0.05 atmosphere, and under the state, 10 hrs charging is carried out, then 6 hrs wating is made to enhance the heat conductivity so that the temperature of a battery may be equal to the temperature before the start of former discharge. Thereafter with the use of a vacuum pump 7 the cover 24 of the vessel 2 is returned to the original state, and the discharge, charge and waiting are repeated in the same manner as before. Accordingly, the balance of discharge current is restrained to prevent decrease in the service life, capacity and efficiency of a battery.

摘要： PROBLEM TO BE SOLVED: To obtain a reliable high temperature sodium secondary battery module in which cooling of a battery is facilitated and damage and extension to adjacent batteries during active substance leakage is hardly generated by separating adjacent batteries by a bulkhead and charging an insulation material outside of the bulkhead. SOLUTION: In a high temperature sodium secondary battery module, individual batteries 2 are separated by a cylindrical bulkhead 3, and a powder-type or fiber-type insulation material 4 is charged outside of the bulkhead 3. Thus, even if a battery is damaged, and an active substance is leaked from a battery container there is no worrying about the leaked active substance being shielded by the bulkhead, and even if it is leaked outside of the bulkhead, it is held and fixed to a gap between particles or fibers of an insulation material; therefore there is no worrying about adjacent batteries being damaged.

摘要： PROBLEM TO BE SOLVED: To provide a system effective in a measure against peak electric power of an electric power system by eliminating uselessness of a conventional secondary battery system. SOLUTION: Integrated electric energy of one day of electric power used by exceeding an electric power value by subtracting AC output capacity of an electric power converter 2 from a peak value of electrice power used in an electric power system 4 and a value by multiplying storage electric energy capacity of a secondary battery by D.C-A.C conversion efficiency of the electrice power converter 2, are made to almost coincide with each other. Or the relationship between the integrated electric energy and AC output is found by using a pattern with the lapse of time of electric power in the past annual electric power peak generating days, and when the integrated electrice energy is equal to the value by multiplying the storage electric energy capacity of the secondary battery 1 by the orthogonal conversion efficiency of the electric power converter 2, AC output capacity of the electric power converter 2 is made larger than a value of AC output calculated from this relationship.
