【発明の詳細な説明】
本発明は密閉型蓄電池の充電方法の改良に係シ、特に安
価にして急速に充電しうる充電方法を提供せんとするも
のである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a charging method for a sealed storage battery, and in particular, it is an object of the present invention to provide a charging method that is inexpensive and allows rapid charging.
一般に蓄電池の充電末期又社過放電時には水の電解によ
りガスが発生する。４Ｉに急速に充電する場合にはガス
の発生が多量となりこれに伴って電池の内圧が急上昇し
液漏れ勢を生じ蓄電池の性能を著しく阻害するφ従って
充電の末期を何等かの方法によル検出し充電電流を小さ
くするとか或は電流を切断する必要があった。Generally, gas is generated due to water electrolysis during the final stage of charging or over-discharging of a storage battery. When charging 4I rapidly, a large amount of gas is generated, which causes the internal pressure of the battery to rise rapidly, causing a leakage force that significantly impairs the performance of the storage battery. It was necessary to detect this and reduce the charging current or cut off the current.
而してこの充電末期を検出するには次の如き方法が行わ
れていたものである。The following method has been used to detect the end of charging.
（１）電池電圧を検出する方法。(1) Method of detecting battery voltage.
（２） クーロメタ−により電気量を検出する方法。(2) A method of detecting the amount of electricity using a coulometer.
（３）補助電極を用いて発生ガスを検出する方法・ （４）電池温度上昇や触媒温度上昇を検出する方法。(3) Method of detecting generated gas using auxiliary electrodes (4) Method of detecting battery temperature rise and catalyst temperature rise.
これらの方法において（１）の方法は一般的ではあるが
充電電流や周囲温度により電圧が変化し正確な値を検出
し難い・又（２）の方法はクーロメタ−という高価な測
定器を必要とし且つ電池との容量差を生ずるものである
。又（３）の方法は正。Among these methods, method (1) is common, but the voltage changes depending on the charging current and ambient temperature, making it difficult to detect an accurate value, and method (2) requires an expensive measuring device called a coulometer. Moreover, it causes a difference in capacity with the battery. Also, method (3) is correct.
負極の外に補助極を設けるため、構造が複雑になるもの
である。又（４）の方法は電池にサーξスターを密着さ
せることが離しく、電池温度と検出温度とにずれを生じ
易く、検出温度がずれると電池は高温になり寿命特性が
劣化する。Since an auxiliary electrode is provided outside the negative electrode, the structure becomes complicated. Furthermore, in the method (4), it is difficult to bring the circulator into close contact with the battery, which tends to cause a deviation between the battery temperature and the detected temperature.If the detected temperature deviates, the battery becomes hot and its life characteristics deteriorate.
従って充電末期を正確にして且つ安価に検出する方法の
出現が要望されていたものであったｅ本発明はかかる要
望に応じ鋭意研究を行り九結果、簡易にして精度のよい
充電方法を見出したものである。即ち本発明方法は充電
せんとする密閉式蓄電池の温度を検知しうる位置に感圧
導電ゴムを取付け、充電時における該蓄電池の温度上昇
により変化する該導電ゴムの抵抗値を検出して充電電流
を停止あるいは制御することを特徴とするものである。Therefore, there has been a demand for a method to accurately and inexpensively detect the end of charging.The present invention has responded to this demand by conducting extensive research, and as a result, has discovered a simple and highly accurate charging method. It is something that That is, in the method of the present invention, a pressure-sensitive conductive rubber is attached at a position where the temperature of the sealed storage battery to be charged can be detected, and the resistance value of the conductive rubber, which changes as the temperature of the storage battery increases during charging, is detected and the charging current is determined. It is characterized by stopping or controlling.
本発明方法は感圧導電がムを使用することを要旨とする
ものであるがその原理を説明すると、感圧導電ゴムは無
加圧時においては高抵抗体であるが加圧すると低抵抗体
となる柔軟性を有するゴム状物質であり、その温度特性
を示すと第１図の如くである。即ち一定圧例えばＰｇ
＊ Ｐｇで加圧していてもある温度に達すると急激に抵
抗が上昇する。この抵抗が上昇する温度は加圧の大きさ
、導電ゴム中に含まれる導電性物質量により変化させる
ことが出来るものである。The gist of the method of the present invention is to use a pressure-sensitive conductive rubber. To explain the principle, the pressure-sensitive conductive rubber has a high resistance when no pressure is applied, but when pressure is applied, it becomes a low resistance. It is a rubber-like substance with flexibility, and its temperature characteristics are shown in Figure 1. That is, a constant pressure, e.g. Pg
* Even when pressurized with Pg, the resistance increases rapidly when a certain temperature is reached. The temperature at which this resistance increases can be changed depending on the magnitude of pressurization and the amount of conductive substance contained in the conductive rubber.
そして感圧導電性ゴムは極めて密着性がよいため取付け
が簡単であり蓄電池の側面等に極めて容易に取付けるこ
とが出来て、蓄電池の温度を正確に検知することができ
る。Since the pressure-sensitive conductive rubber has extremely good adhesion, it can be easily attached to the side surface of the storage battery, and the temperature of the storage battery can be detected accurately.
本発明はこのような感圧導電ゴムの特性を利用して蓄電
池の温度検出体としたものである。The present invention utilizes the characteristics of pressure-sensitive conductive rubber as a temperature sensor for storage batteries.
即ち感圧導電ゴムを蓄電池の充電に伴うて温度の上昇を
検知しうる位置例えば電池の表面、電極表面或は補助極
表面に一定圧にて密着せしめ導通状態で設置すればよく
、蓄電池の温度がある点に達すると急激に抵抗が増大す
るものである。従ってこの抵抗値の立上りを電気的にと
らえることにより充電電流を制御すればよい。In other words, the pressure-sensitive conductive rubber may be placed in a conductive state at a position where the temperature rise due to charging of the storage battery can be detected, such as by bringing it into close contact with the surface of the battery, the electrode surface, or the surface of the auxiliary electrode at a constant pressure. When the resistance reaches a certain point, the resistance increases rapidly. Therefore, the charging current can be controlled by electrically capturing the rise in resistance value.
なお、感圧導電ゴムを蓄電池の内部空間に設置する場合
には、該導電性ゴムをリード板間にはさみ込み、ある一
定圧でかしめ導通状態にしておくことが必要である。In addition, when the pressure-sensitive conductive rubber is installed in the internal space of the storage battery, it is necessary to sandwich the conductive rubber between lead plates and caulk it with a certain pressure to make it conductive.
次に本発明の実施例について説明する。Next, examples of the present invention will be described.

固定し密閉型蓄電池をえた。Example: A sealed cylindrical lid storage battery with a positive electrode capacity of 3.5 μm and a negative electrode capacity of 7.5 μm. An OAh cylindrical nickel-cadmium storage battery was constructed.As shown in Fig. 2, a pressure-sensitive conductive rubber 3 and a lead wire 4 were crimped onto the surface of the battery 1 via a metal tube 2 to form a negative electrode (battery can). A sealed storage battery was created by making the lead and the lead conductive and fixing the metal tube.

整用抵抗体である。The battery thus obtained was charged using a circuit as shown in FIG. That is, in this circuit, during initial charging by the charger 6, the battery temperature does not rise and the pressure-sensitive conductive rubber 8 is in a conductive state, so that the thyristor 1 is brought into conduction and rapid charging is possible. However, at the end of charging, the temperature of the battery rises, for example, when it reaches 45° C., the resistance of the pressure-sensitive conductive rubber 3 suddenly increases, causing the thyristor 1 to become non-conducting, and charging is completed. Incidentally, in place of the SIRISK, a TRA/X) STAR may be used. In the figure, 0 indicates an adjusting resistor connected in series with the pressure-sensitive conductive rubber J.
