〔産業上の利用分野〕
この発明は主として自動車に積載される蓄電池装置の改
良に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention mainly relates to improvements in storage battery devices mounted on automobiles.
第４図は従来の蓄電池装置を示す断面図であり、図にお

された電極板、（４）は端子である。FIG. 4 is a sectional view showing a conventional storage battery device. In the figure, (1) is a first tank, (2) is an electrolytic solution such as dilute sulfuric acid injected into this first premises, and (3) is a sectional view showing a conventional storage battery device. is an electrode plate immersed in this electrolyte, and (4) is a terminal.
この様に構成された蓄電池は、自動車の機関室内に装着
され、自動車の各種電気負荷に電気を供給すると共に機
関に駆動される交流発電機の整流出力により充電される
。The storage battery configured in this manner is installed in the engine room of an automobile, supplies electricity to various electrical loads of the automobile, and is charged by the rectified output of an alternating current generator driven by the engine.
ところで、自動車の機関近傍に積載される蓄電池はその
雰囲気温度の影響を受けて電解液（２）の温度が上がる
。一般にこの電解液（２）の温度上昇は時間に相関して
おり、最終的に雰囲気温度と同じ程度になる。蓄電池の
機能は電解液（２）の温度が６０℃位までは正常に維持
されるが、これを越えると蓄電池の受入電圧の低下等の
ために充電発電機の制御電圧が正常であっても電解液（
２）が沸騰して見かけ上の過充電が発生し、電解液（２
）が消失することがある。この現象は、特に自動車の機
関がアイドル状態で長時間例えば数時間放置された時に
雰囲気温度が高くなり、したがって蓄電池電解液（２）
の温度が６０°Ｃを越える機会が増える。By the way, the temperature of the electrolyte (2) of a storage battery loaded near the engine of a vehicle increases due to the influence of the ambient temperature. Generally, the temperature rise of this electrolytic solution (2) is correlated with time, and eventually reaches the same level as the ambient temperature. The function of the storage battery is maintained normally until the temperature of the electrolyte (2) reaches around 60℃, but if it exceeds this temperature, the voltage accepted by the storage battery will drop, even if the control voltage of the charging generator is normal. Electrolyte (
2) boils and an apparent overcharge occurs, causing the electrolyte (2) to boil and cause an apparent overcharge.
) may disappear. This phenomenon occurs especially when the engine of a car is left in an idling state for a long time, for example, several hours, when the ambient temperature becomes high, and therefore the battery electrolyte (2)
The chances of the temperature exceeding 60°C increase.
従来、蓄電池の電解液（２）の量は蓄電池の電気的容量
を主体として決められているが、雰囲気の影響による液
温の温度上昇を抑制するのに必要な熱容量の配慮がされ
ていなかった。Conventionally, the amount of electrolyte (2) in a storage battery has been determined mainly based on the electrical capacity of the storage battery, but consideration has not been given to the heat capacity necessary to suppress the rise in liquid temperature due to the influence of the atmosphere. .
したがって電解液（２）の沸騰を防止するため、電気的
に８ＯＡＨの容量で充分である所へ６ＯＡＨの容量を有
するものに置換するということが経験的に実施されてい
た。これは熱容量が増して電解液（２）の温度の上昇に
時間がか＼るために問題が発生しないわけである。しか
し経済的に見た時、高価格となる問題点を有していた。Therefore, in order to prevent the electrolytic solution (2) from boiling, it has been empirically carried out to replace the electrolytic solution (2) with one having a capacity of 6 OAH in places where a capacity of 8 OAH is electrically sufficient. This is because the heat capacity increases and it takes time for the temperature of the electrolytic solution (2) to rise, so no problem occurs. However, from an economic point of view, it had the problem of being expensive.
この発明は上記のような問題点を解消するためになされ
たもので、熱容量の大きな蓄電池を安価に得られる蓄電
池装置を提供することを目的とする。This invention was made to solve the above-mentioned problems, and an object thereof is to provide a storage battery device that can obtain a storage battery with a large heat capacity at a low cost.
〔問題点を解決するための手段〕
この発明に係る蓄電池装置は、蓄電池の周囲に液体を介
在させて蓄電池の熱容量を大きくしたものである。[Means for Solving the Problems] The storage battery device according to the present invention has a liquid interposed around the storage battery to increase the heat capacity of the storage battery.
この発明のものにあっては、実質的に熱容量の大きな蓄
電池となるので、蓄電池の周囲温度のと昇に比して蓄電
池の電解液の温度上昇を抑制することができる。In the case of the present invention, since the storage battery has a substantially large heat capacity, the rise in temperature of the electrolytic solution of the storage battery can be suppressed compared to the rise in the ambient temperature of the storage battery.
以下、この発明の一実施例を図について説明する。 An embodiment of the present invention will be described below with reference to the drawings.
まず、第１図において、（５）は蓄電池の周囲に全周に
亘って設けられた第２の槽で、と記第１の槽（１）と一
体に形成されている。（６）はこの第２の槽内に注入さ
れた油又は水のような冷却用の液体である。First, in FIG. 1, (5) is a second tank provided around the entire circumference of the storage battery, and is formed integrally with the first tank (1). (6) is a cooling liquid such as oil or water injected into this second tank.
このように構成された実施例のものにあっては。In the embodiment configured in this way.
蓄電池の電解液（２）の周囲に冷却用の液体（６）が充
填されているので、蓄電池の熱容量が従来のものより大
となり、その結果、電解液（２）の温度上昇が抑制され
、電解液が６０℃に達するまでの時間が長くなり、過充
電に到るのを防止できる。Since the cooling liquid (6) is filled around the electrolyte (2) of the storage battery, the heat capacity of the storage battery is larger than that of conventional ones, and as a result, the temperature rise of the electrolyte (2) is suppressed. The time it takes for the electrolyte to reach 60°C becomes longer, and overcharging can be prevented.
第２図はこの発明の他の実施例を示すもので、蓄電池の
底部まで、第２の槽（５）を拡大したもので、図中、（

7) Ha! A cooling liquid such as oil or water is filled in a second tank (6) formed at the bottom of the battery.
この様に構成すれば第１図の実施例のものに比して蓄電

本発明のものは液温の上昇が遅れることを示す。一般に
車両は無制限に連続的に運転されることは少なく、最も
長くて１日を単位とするものであるから、この条件の中
で蓄電池の電解液温が所定値を越えないように水量を決
めることによって、実質的に常に蓄電池を正常な機能を
維持することができる６０℃以下に電解液の温度を保つ
ことができる。FIG. 3 compares the rise in liquid temperature when the storage battery of the present invention and the conventional storage battery are left in an atmosphere of 100'C. In the figure, the horizontal axis shows the standing time, and the vertical axis shows the rise in electrolyte temperature. In contrast to the conventional broken line showing the temperature rise, the solid line of the present invention shows that the rise in liquid temperature is delayed. In general, vehicles are rarely operated continuously without limit, and the maximum length of time is one day, so the amount of water is determined so that the temperature of the electrolyte in the storage battery does not exceed a predetermined value under these conditions. By doing so, the temperature of the electrolyte can be kept substantially always below 60° C., which allows the storage battery to maintain its normal function.
以上のように、この発明によれば蓄電池の周囲に比較的
熱容量の大きい水のような液体を介在することによって
、実質的に熱容量の大きな蓄電池と等価となり、しかも
熱容量的に等価な従来の蓄電池に比較して安価に構成す
ることが出来る。As described above, according to the present invention, by interposing a liquid such as water with a relatively large heat capacity around the storage battery, it becomes substantially equivalent to a storage battery with a large heat capacity, and moreover, it can be made similar to a conventional storage battery that is equivalent in terms of heat capacity. It can be constructed at a low cost compared to the .
