Insert a thermistor into the hole dug deep from the top of the lid,
Further, a form in which an adhesive is filled and hermetically fixed on the upper surface of the lid has been adopted.

い電池を提供する必要があった。However, in the conventional structure, since the upper surface of the lid is dug deep to bury the thermistor, the back surface of the lid penetrates into the inside of the battery case, and the electrode plate inserted into the battery case is formed. This has had an effect such as reducing the space for group arrangement. For this reason, it is necessary to provide a battery that has a smaller shape protruding from the back surface of the lid, secures a sufficient storage space for the electrode plate group in the battery case, and does not lower the detection sensitivity of the thermistor.

る。SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a heat collecting structure for a group of electrode plates, such as terminals having different polarities and inter-cell connectors, which better reflects the temperature inside a battery to a detecting portion. With a structure in which the thermistor is embedded near the body, the depth of the thermistor embedded is reduced to reduce the amount of protrusion from the back of the lid, and the temperature transmission time from the electrode group is shortened, resulting in good detection sensitivity. It has a battery structure.

成である。Since the dead space formed between the upper part of the electrode group and the inside of the lid does not fulfill the function of improving the battery characteristics, this dead space is filled from the top of the lid from the outside in order to make effective use of this space. In this configuration, a recess is provided in the shape, and the thermistor and the connector are housed in the recess.

ている。DESCRIPTION OF THE PREFERRED EMBODIMENTS In the storage battery of the present invention having the above-described structure, a group of electrode plates is housed in each cell chamber of a battery case, and a group of electrode plates such as terminals having different polarities of adjacent cells and inter-cell connectors. A thermistor detection unit is arranged above and close to the heat collection unit.

に配置したサーミスタの表面を加熱することになる。Therefore, the heat inside the battery generated when charging or discharging the storage battery raises the temperature of the electrode group, and forms the ears of the electrode plate current collector, the shelf connecting these, and the shelf. The heat is transmitted to the different polarity terminal and the inter-cell connector, thereby increasing the temperature in the vicinity thereof and heating the surface of the thermistor disposed near the heat collecting portion.

る。Further, since the thermistor is mounted by being inserted into the lateral hole of the upper surface concave portion of the lid which covers the upper opening of the battery case, the thermistor is hardly affected by the external air flow and the internal temperature of the battery is faithfully controlled. A reflected battery can be provided.
