産業上の利用分野
本発明は蓄電池の電解液撹拌に関するものであ
る。DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to electrolyte stirring for storage batteries.
従来技術とその問題点
蓄電池を浅い充放電で使用するか小さい電流で
充電するときは、電解液の拡散が悪く、このため
蓄電池の上部電解液と下部電解液との濃度が異な
るようになる。即ち上部電解液比重は低くなり、
下部電解液比重は高くなり、こうして電解液比重
が不均一となるので、蓄電池は容量面及び寿命面
において悪影響を受ける。Prior Art and its Problems When a storage battery is used in a shallow charging/discharging process or is charged with a small current, the electrolyte diffusion is poor, which causes the concentrations of the upper and lower electrolytes of the storage battery to be different. In other words, the upper electrolyte specific gravity becomes lower,
The specific gravity of the lower electrolyte becomes high and thus the specific gravity of the electrolyte becomes non-uniform, so that the storage battery is adversely affected in terms of capacity and life.
この悪影響解消のため通常は充電々流が大きく
なる均等充電を適宜実施して極板からガスを発生
させて電解液撹拌を行うのであるが、近年、充電
設備の小型化の要求のため、あるいは太陽電池と
組み合わせて該太陽電池のバツクアツプ電源とし
て使用するものでは、充電々流を大きくすること
ができなくなつてきており、電解液を十分に撹拌
することが困難となつている。 In order to eliminate this negative effect, normally uniform charging is carried out as appropriate in which the charging current becomes large, and gas is generated from the electrode plates to stir the electrolyte, but in recent years, due to the demand for downsizing of charging equipment, When used in combination with a solar cell as a backup power source for the solar cell, it has become impossible to increase the charging current, and it has become difficult to sufficiently stir the electrolyte.
発明の目的
本発明は無動力の電解液撹拌機能を有する長寿
命な蓄電池を提供することを目的とする。OBJECTS OF THE INVENTION An object of the present invention is to provide a long-life storage battery having a non-powered electrolyte stirring function.
発明の構成
本発明は上記の目的を達成すべく、蓄電池外部
に容積の一定なタンクを備えて、該タンクと連通
した容積変動する膨張収縮の自在な柔軟体を電池
の電解液内に備えるものである。Structure of the Invention In order to achieve the above-mentioned object, the present invention is provided with a tank having a constant volume outside the storage battery, and a flexible body communicating with the tank that is capable of expanding and contracting and whose volume fluctuates within the electrolyte of the battery. It is.
又容積の一定なタンクは、電池室外の屋外に配
置するものである。 Also, a tank with a constant volume is placed outdoors outside the battery room.
実施例
以下、本発明をその一実施例を示す図面により
説明する。Embodiment Hereinafter, the present invention will be explained with reference to drawings showing one embodiment thereof.

いる。外部タンクは容積変化を生じないので、気
温の上昇により、外部タンク内のガス圧力は上昇
する。この時、柔軟体は連通管によつて連結され

張・収縮によつて、電池電解液面が上昇、降下を
おこし、電解液を撹拌させる。 FIG. 1 is a schematic diagram of the storage battery of the present invention. 1 is a storage battery, 2 is a flexible body that expands and contracts in the electrolyte of the storage battery, and 3 is a communication pipe that communicates with an external tank 4 that does not change its volume outside the storage battery. gas is enclosed. Since the external tank does not undergo a volume change, an increase in temperature will cause the gas pressure in the external tank to increase. At this time, since the flexible bodies are connected by the communication pipe, the flexible bodies expand due to changes in gas pressure. Furthermore, when the temperature drops, the flexible body also contracts due to the change in gas pressure as the gas pressure in the external tank decreases. In this way, the expansion and contraction of the flexible body causes the level of the battery electrolyte to rise and fall, stirring the electrolyte.
こゝにおいて、外部タンクを屋外に配置するこ
とによつて、気温の変化が大きくなり、ガス圧の
変動が大きくなりより効率的に電解液を撹拌する
ことができる。 In this case, by arranging the external tank outdoors, the change in temperature becomes large, and the fluctuation in gas pressure becomes large, so that the electrolyte can be stirred more efficiently.
本発明による蓄電池と従来の撹拌機能を有しな
い蓄電池の寿命性能を比較した結果、本発明によ
る蓄電池は、従来蓄電池よりも２倍以上長寿命で
あつた。 As a result of comparing the life performance of the storage battery according to the present invention and the conventional storage battery without a stirring function, the life of the storage battery according to the present invention was more than twice as long as that of the conventional storage battery.
又、電池外部のタンクについて複数個の単電池
に接続することも可能である。 It is also possible to connect a plurality of single cells to a tank outside the battery.
