Description
【発明の詳細な説明】 （産業上の利用分野） 本発明は、クラッド式鉛蓄電池の充電方法に関する。[Detailed description of the invention] (Industrial application field) The present invention relates to a method for charging a clad lead-acid battery.
（従来の技術）
クラッド式鉛蓄電池の極板は、その表面の大部分がガラ
ススリーブで覆われていて活物質と化成液との接触部分
が僅かであるので、ペース−１−へへ〇
ト式極板に比べて化成効率が悪い。(Prior art) Most of the surface of the electrode plate of a clad lead-acid battery is covered with a glass sleeve, and the contact area between the active material and the chemical solution is small, so go to Pace-1- The chemical conversion efficiency is lower than that of formula plates.
従来、このクラッド式鉛蓄電池の充電方法としては、理
論化成電気量の３００〜３５０％の充電量を１０ｍ＾／
ｇの一定電流密度で一定時間通電していた。Conventionally, the charging method for this clad lead-acid battery is to charge 300 to 350% of the theoretical amount of electricity at 10m^/
The current was applied for a certain period of time at a constant current density of g.
（発明が解決しようとする問題点）
しかし、この充電方法によれば、第３図示の蓄電池端子
電圧特性から明らかなように、充電がある程度進行する

った。(Problem to be Solved by the Invention) However, according to this charging method, as is clear from the storage battery terminal voltage characteristics shown in Figure 3, once charging has progressed to a certain extent, most of the charge is due to water electrolysis. Since it is consumed, there is an inconvenience that the chemical conversion efficiency is low. Further, there were disadvantages such as non-uniform chemical formation due to continuous and intense gas generation.
本発明は、従来のこのような問題点を解消し、短時間で
充電でき、かつ充電量が少なくてよく、更に化成のばら
つきの少ない品質の安定した極板が１ｑられるクラッド
式鉛蓄電池の充電方法を提供することをその目的とする
。The present invention solves these conventional problems and provides a charging method for clad lead-acid batteries that can be charged in a short time, requires only a small amount of charging, and can produce 1 q of plates of stable quality with little variation in chemical composition. Its purpose is to provide a method.
（問題点を解決するための手段）
本発明は、上記目的を達成するために、定電流で充電を
行ない、蓄電池端子電圧が所定値に達する毎に前Ｊこり
低減し１．、：定電流で充電１Ｊる蓄電池の充電方法に
おいて、充電開始後前記端子電圧が始めて前記所定値に
達し−Ｃ充電電流を低減した定電流に切り換えた１１．
〜の該端子電圧が、ガス発生電圧付近と／【るように前
記所定値を設定したことを特徴と覆る。(Means for Solving the Problems) In order to achieve the above objects, the present invention performs charging with a constant current, and reduces the front J stiffness each time the storage battery terminal voltage reaches a predetermined value.1. 11.: In a method of charging a storage battery that charges 1 J with a constant current, the terminal voltage reaches the predetermined value for the first time after charging is started, and the -C charging current is switched to a reduced constant current.11.
The predetermined value is set so that the terminal voltage of ~ is around the gas generation voltage.
（実施例） 以下、本発明の実施例を図面につき説明する。(Example) Embodiments of the present invention will be described below with reference to the drawings.
化成初期の電流密度を、例えば従来方法と同じように、
Ｉｆ＝ １０ｍＡ／ ｓｌどしてクラッド式鉛蓄電池の
充電を開始する。For example, the current density at the initial stage of chemical formation is set to the same as in the conventional method.
If = 10 mA/sl, start charging the clad lead-acid battery.
充電が進行して電池端子電圧が所定値、例えば第１図示
のようにセル当り２．６ｖに達した時に、電流密度を第
２図示のように０．５Ｔｆとする。When charging progresses and the battery terminal voltage reaches a predetermined value, for example 2.6 V per cell as shown in the first diagram, the current density is set to 0.5 Tf as shown in the second diagram.
充電が進み再び端子電圧が２．６■に達した時、電流密
度を更に０．２５１ｆに半減する。以後同様に、端子電
圧が２，６ｖに達づる毎に電流密度の半減すなわち０．
１２５ｒｆ、 ０．０Ｇ２５１ｆ・・・・・・を繰り
返す。そして電流！Ｉｉ度が０．０５Ｉｆ以下になった
時充電を終了する。When charging progresses and the terminal voltage reaches 2.6μ again, the current density is further halved to 0.251f. Thereafter, similarly, each time the terminal voltage reaches 2.6V, the current density is halved, that is, 0.
125rf, 0.0G251f...repeat. And electric current! Charging is terminated when Ii degree becomes 0.05If or less.
蓄電池端子電圧の前記所定値は、定電流で充電を開始し
、該端子電圧が始めて該所定値に達して充電電流を前よ
り低減した定電流に切換えた時の該端子電圧が、ガス発
生電圧（２，４ｖ）付近どなるような値に設定する。The predetermined value of the storage battery terminal voltage is the gas generation voltage when charging is started with a constant current, and when the terminal voltage first reaches the predetermined value and the charging current is switched to a constant current that is lower than before. Set it to a value around (2,4v).
かくて、電流密度を半減しながら充電を行なっている時
、蓄電池端子電圧は、最初に２．６ｖに達した時以後、
ガス発生電圧以上に保持される。そしてその間、端子電
圧の高低に応じて増減して発生するガスによって、化成
液が常に適度に攪拌され、その濃度は均一となる。した
がって充電時間は短縮されると共に充電１は低減され、
また極板はほぼ均一に化成される。Thus, when charging is carried out while reducing the current density by half, the battery terminal voltage will decrease from the time it first reaches 2.6V.
Maintained above the gas generation voltage. During this time, the chemical liquid is constantly agitated appropriately by the gas generated, which increases or decreases depending on the level of the terminal voltage, and its concentration becomes uniform. Therefore, charging time is shortened and charging 1 is reduced,
Further, the electrode plate is chemically formed almost uniformly.
蓄電池の端子電圧の前記所定値は、２，６■が最適で、
それ以上では水の電気分解を余り押えることができない
から、充電量が従来のものとあまり変らなくなり、２．
６ｖ以下では充電に長時間を要するようになる。また、
電流密度の低減率は０．５が最適でそれ以上では無駄な
水の電気分前をあまり押えることができず、０．５以下
では充電に長時間を要する。The predetermined value of the terminal voltage of the storage battery is optimally 2.6■,
Above that, water electrolysis cannot be suppressed very much, so the amount of charge will not be much different from the conventional one, and 2.
If the voltage is less than 6V, it will take a long time to charge. Also,
The optimum current density reduction rate is 0.5; if it is more than that, it is not possible to save much electricity from wasted water, and if it is less than 0.5, it takes a long time to charge.
以上の充電方法の実施は、周知の回路構成によって行な
う。すなわち、充電回路として定電流回路を用い、蓄電
池端子電圧が所定値に達した時、例えば電圧検出回路で
これを検出し、その出力で定電流回路の設定値を切替え
るような回路を使用する。The above charging method is implemented using a well-known circuit configuration. That is, a constant current circuit is used as the charging circuit, and when the terminal voltage of the storage battery reaches a predetermined value, for example, a voltage detection circuit detects this, and the output thereof is used to switch the set value of the constant current circuit.

端子電圧の２．６ｖ／ｌル１σに充電電流密度を低減し
て充電した時と、充ｆｆｉ電流密度をＩＩ’＝ １０ｍ
Ａ／ｇ一定として充電を行なった時の充電時間及び総充
電流の比較を示す。The table below shows a clad lead-acid battery with a nominal capacity of 90Ah, assuming that the charging N flow density surface at the initial stage of formation is If = 10mA/g.
When charging is performed by reducing the charging current density to 2.6v/l of the terminal voltage 1σ, the charging current density is II' = 10m
A comparison of charging time and total charging current when charging is performed with A/g constant is shown.
