摘要： PROBLEM TO BE SOLVED: To provide a heat insulating container for batteries which is satisfactory from view points of space and cost without greatly lowering the practical heat efficiency by forming a joining part of a container main body and a cover in a vacuum heat insulating container of a battery module into a specified shape. SOLUTION: Regarding a sodium sulfur battery, battery elements 4 are integrated to give a module and the module is housed in a heat insulating container to operate the module. In the case a vacuum heat insulating container is used as the heat insulating container, the joining part of a container main body 1 and a cover 5 is made to be a taper shape 8 or an arc-like shape 10. The vacuum heat insulating container is made of a metal and heat radiation out of the joining part is high due to transmission to the metal. Consequently, the heat radiation through the metal is suppressed by lengthening the length of the joining part in the described manner.

摘要： PURPOSE:To early and surely cut a generation part of abnormal temperature, when it is generated, by connecting between cells by a conductor fused at a specific temperature. CONSTITUTION:Many cells are arranged in a heat insulating vessel, and a battery module is constituted by connecting a negative pole 4' and a positive pole 12 in series and parallel by a connecting conductor 10. Here, the connecting conductor 12 is made by a metal material of melting temperature a little higher than normal operation temperature of the cell and further lower than a melting point of the lowest melting point material of the constitutional materials of the cell. Thus in the case such as rapidly increasing a temperature in the heat insulating vessel by contact between sodium and sulfur due to damaging an electrolyte and by short-circuiting in the module, the connecting conductor of low melting point metal is melted to enable an abnormality generation part to early and surely separate.

摘要： PURPOSE:To reduce direct reaction of sodium with sulfur in the event of battery breakage and enhance the safety by furnishing a member having a lower porosity than conventional fibers at or in the neighborhood of a sodium flowout hole provided in a metal vessel. CONSTITUTION:A metal vessel 5 furnished inside of a solid electrolyte pipe 1 contains sodium 8 as a neg. electrode active substance, and the sodium flows in from the flowout hole 5A at the bottom of the vessel 5 toward the electrolyte pipe 1. The gap between the pipe 1 and vessel 5 is filled with metal fibers 6 which ffed the sodium 8 to the inside surface of the pipe 1. These fibers 6 of several micrometers in dia. shall be compressed so as to have a porosity of 93-97%. The cylindrical fiber 6 bottom 6A shall be located between the vessel 5 and a metal ring 7, which is tightened in the direction of the pipe 1 so as to give a specified porosity. The rate of Na flow from the flowout hole 5A is restricted by allowing the bottom 6A porosity to range 71-89%, and thereby enlargement of direct reaction in the event of pipe 1 breakage is suppressed.

摘要： PURPOSE:To enhance estimation accuracy by obtaining the number of defectless series units from a difference between the series-parallel units of discharge depths, adding the correction by the total number of the series unit to the energization quantity of a set battery with the discharge depth as a beginning point and calculating the respective discharge depths. CONSTITUTION:The set battery 8 is housed into a heat insulating box 10 where the series-parallel units 6 are connected in series. A voltmeter 14 measures the voltage across the units 6 and an ammeter 16 measures the current flowing in external terminals 12a, 12b. The electromotive force E of the units 6 is estimated from a change with time, of the voltage of the units 6 right after the stop of the charge and discharge and the discharge depth D of the units 6 is obtd. by collating the electromotive force E and the theoretical value. The number K of the defectless series units of the units 6 is obtd. by making comparison with depths D each other between the units 6. The charging and discharging current quantity Ah of the battery 8 is obtd. by integrating the current value measured by the ammeter 16 with time and can be referenced at all time. The residual capacity R of the battery 8 is calculated from the max. of the depth D of the units 6, the number K of the units and the number K of the units of the battery 8.
