に収納されている。2. Description of the Related Art Generally, a battery storage case of a sodium-sulfur battery is composed of a case body having an upper opening and a lid sealed to the opening. A battery block in which a large number of single cells of sodium-sulfur batteries are connected in a predetermined arrangement is housed in the battery housing case. Further, the battery storage case is stored in a vacuum heat insulation container for keeping heat. That is, as shown in FIG. 5, the battery storage case 1 is a rectangular container, and the lid 2 is sealed on the open upper surface thereof. A large number of unit cells 3 are housed in the battery housing case 1, and the unit cells 3 are connected by a connection terminal 4 and a parallel connection line 5 to form an assembled battery. Insulating sand is filled in the gaps between the unit cells 3 in the battery storage case 1 to fix the unit cells 3 so as not to sway, and at the same time enhance the safety of the batteries.

Therefore, the battery storage case 1

１が早期に寿命に至るという問題点があった。In the above-mentioned conventional assembled battery, the battery storage case 1 is made of a durable iron plate or steel plate, and an insulating material layer is provided between the battery storage case 1 and the battery block. In some cases, even if a small number of electric heaters 11 are installed on the outer peripheral surface of the battery storage case 1 at intervals, the temperature gradient is relaxed before reaching the battery block, so unless rapid heating is performed, The temperature distribution did not become non-uniform. However, in order to reduce the size and weight of the battery, the battery storage case 1
Needs to be thin and the gap between the battery block and the battery storage case 1 must be small. In addition, once the temperature is raised, it is not intended to be used at that temperature for a certain period of time, but in the case where it is desired to store it at room temperature and quickly heat it when necessary, to shorten the time required for raising the temperature. First, it is necessary to increase the electric power of the electric heater 11. In such cases,
In particular, in the temperature rising process, the temperature distribution becomes uneven between the part where the electric heater 11 is installed and the part where the electric heater 11 is not installed on the outer peripheral surface of the battery storage case 1, and the locally heated single part is not heated. In the battery 3, the thermal stress generated at that time may be concentrated. Further, in the conventional assembled battery, a cylindrical electric heater 11 having a relatively large diameter is often used, and when the electric heater 11 is attached to the outer peripheral surface of the battery storage case 1, the battery storage case 1 However, the heat conduction between the electric heater 11 and the battery storage case 1 is insufficient, and the electric heater 1
There was a problem that 1 reached the end of life early.

りなる集合電池である。In order to solve the above-mentioned problems, the invention according to claim 1 is a battery case in which a plate-shaped heating device in which electrically insulating plate members are arranged on both upper and lower surfaces of a heating wire is integrated. It is an assembled battery composed of a sodium-sulfur battery installed on the inner bottom surface of the.

る。As a result, the heating device can relax the gradient of the temperature distribution on the surface and heat all the unit cells housed in the battery housing case from the bottom. On this occasion,
Since the metal battery case of all the upright cells serves as a good conductor of heat and only some of the cells are not overheated, it is possible to reduce the concentration of thermal stress on the cells. Further, since the heating wire has a smaller space than the electric heater installed in the conventional assembled battery, there is also an effect that the efficiency of the accommodation space for accommodating the heating device is improved.

ことができる。Further, if a large number of irregularities are formed on the surface of the electrically insulating plate material arranged on the upper surface of the heating wire, the contact area between the heating device and the unit cell is reduced, which is often considered to be disadvantageous for heat transfer. However, if the irregularities are formed into a continuous or intermittent groove shape or a shape similar to this, the concave portion between the heating device and the unit cell uses gas (usually air) as a heat transfer medium, and there is a gap between the unit cells. If so, the heated air can have good heat conduction upward due to convection, and the temperature distribution can be made uniform.
