The optimum operating temperature of a high-temperature battery is selected depending on its constituent active material, constituent materials, structure, etc. As a typical example, a sodium-sulfur battery is approximately
350℃, lithium-sulfur batteries about 400℃, lithium-chlorine batteries about 600℃. If the operating temperature is lower than the optimum operating temperature, the battery cannot operate satisfactorily due to the influence of limitations on the active material diffusion region due to the state (solid or molten state) of the constituent active materials, limitations on the active material composition, and the like. In addition, if the operating temperature is higher than the optimum operating temperature, it will have a large effect on the structure of the constituent active materials and constituent materials, causing distortion of the battery structure due to thermal expansion of the constituent materials, and furthermore, if the temperature exceeds the boiling point of the active material,
It can also lead to battery damage. Therefore, maintaining an optimum operating temperature is an important issue in high-temperature battery devices.
There are three reasons why the temperature may rise above the optimum operating temperature. The first is a failure of the system that supplies the heat necessary to maintain the operating temperature (heat source, heat exchanger, heater, control circuit, etc.), and the second is the internal heat generation of high-temperature batteries (a sudden increase in internal resistance). The third case is the case where the generation of Joule heat due to current flow is significant.The third case is the case where the chemical reaction heat of the constituent active materials is caused by battery destruction. If it is difficult to maintain the optimum operating temperature during battery operation, it is important to immediately lower the battery temperature by operating the cooling system. However, unlike room-temperature battery devices, high-temperature battery devices undergo temperature cycles (increase, maintenance, and decrease in temperature), resulting in loss of operating time and loss of heat when the temperature rises again, and the operation of the cooling system is limited. It is desirable to avoid using it as much as possible, except in the case of a failure of the heat supply system (the first cause). However, significant internal heat generation (second cause) and battery destruction (third cause)
If this occurs and it is necessary to immediately replace the abnormal battery with a normal battery, the cooling system will be activated. In conventional high-temperature battery devices, when abnormal heat occurs, a heat-sensitive element (bimetal,
heat-sensitive fuses, etc.). the result,
When the cooling system and heat-sensitive element were activated, the operating temperature of the battery would drop, and it would take a large amount of time to quickly restore the power circuit, making continuous operation impossible in an emergency.

おいても連続作動させることを目的としたもの
で、高温型電池の最適作動温度を超える異常熱の
発生した電池と正常な電池との接続体の一部を溶
融させることにより電力回路より切り離すと共
に、溶融した接続体の一部により迂回回路を形成
することを特徴としたものである。 The purpose of the present invention is to enable continuous operation even in an emergency situation in which such an abnormal battery occurs, and is intended to provide a connection body between a battery that has generated abnormal heat exceeding the optimum operating temperature of a high-temperature battery and a normal battery. This is characterized in that it is disconnected from the power circuit by melting the connecting body, and that a detour circuit is formed using the melted part of the connecting body.

ボードの使用が可能である。Example 1 As a high-temperature battery device of the present invention, a lithium-chlorine battery was used as a high-temperature battery, and a prototype was produced as shown in Fig. 2.
The operating temperature was maintained at 600℃ in a high-temperature hot air electric furnace. Five unit batteries were connected in series, and the battery voltage was recorded. One of the unit batteries used was a battery with extremely high internal resistance so that abnormal heat would be generated when energized. The connecting body material is all nickel, and the fused connecting wire 2 is made of silver solder (JIS BAg-5
), and the maximum safe temperature was set at 750℃ due to battery structure and other factors. Temperature of each unit battery (temperature at the center of the side of the battery at the start of energization: 600°C) and temperature of the connected body (temperature at the side of the melted connector at the start of energization: 600°C)
While measuring, current application (1 hour rate discharge) was started. As a result, 20 minutes after the start of energization, the temperature of the battery with extremely high internal resistance reached 680°C, but the temperature of the connected body was 670°C. When the battery continued to discharge, the temperature of the battery reached 750℃, and the temperature of the connected body increased to 750℃.
When the temperature reached 740°C, the total series voltage value decreased, but the discharge was able to continue. The decreased voltage value was equal to the terminal voltage value of the battery in which abnormal heat occurred, and it was confirmed that the battery was disconnected by the connecting body of the present invention and that a detour circuit was formed by the detour circuit connecting wire. . The temperature difference between the battery temperature and the connection body temperature at this time is about 10°C, and by changing the components of the fusion connection wire, it is easy to operate at a melting temperature that is lower by the temperature difference. or,
The effect of the insulation wall to prevent further fire due to abnormal heat is good, and the outside temperature of the battery where abnormal heat has occurred is up to 650℃.
It was warm at ℃. We used ceramic wool with a thickness of 3 mm as the heat insulating wall, but depending on the temperature,
Glass wool, rock wool, calcium silicate board can be used.

ことができる。Example 2 A structure was prototyped to test the effects of the present invention even when the amount of abnormal heat generated was extremely small, and tests were conducted. As shown in FIG. 4, the structure is such that a good electrical conductor 16, which is always in a molten state at the operating temperature of a high-temperature battery, is inserted into a molten connection wire 2 that melts due to temperature rise due to abnormal heat generation. Further, the thickness of the vertical side surface 17 of the fusion connecting wire 2 was set to 0.1 to 0.5 mm. When extremely small abnormal heat is generated, the vertical side surface easily melts, and the molten good electrical conductor 16 immediately falls, disconnecting the battery in which abnormal heat has occurred from the power circuit and forming a detour circuit. be able to. As a good electrical conductor 16 that is always in a molten state at the operating temperature of such a high-temperature battery, lead-based solder or the like is suitable. Furthermore, if the melting connection wire 2 and the vertical side surface 17 are made of different materials and the melting temperature difference between them is set to the following relationship, the effect can be further improved.

In some cases (very close to the operating temperature of high-temperature batteries, T C ), they may melt due to localized heat that has little effect on battery operation. Therefore, each melting temperature depends on the battery used,
It is necessary to consider and decide based on the structure and location.

A molten connection wire is interposed to make the main connection wires electrically non-conductive, and a contact body hanging down from one of the main connection wires is internalized without electrical contact, and the molten metal that has melted and fallen is A connecting box for storing the connecting wire is provided, and a bypass circuit connecting wire to be connected to another high-temperature battery is connected to this connecting box, and the molten connecting wire that has melted and fallen is stored in the connecting box and connected to the contact body. A high-temperature battery device characterized in that a detour circuit is formed by electrically contacting a connection box.
