本発明は電池の劣化状態を指示する機能を持つ

定して電池性能の劣化程度を管理する必要があ
る。 Sealed lead-acid batteries use a liquid retaining material such as gel or porous material to make the electrolyte non-fluid, and prevent the water in the electrolyte from decreasing due to the sealing reaction of the oxygen cycle. However, when left unused, float charged, or charged/discharged, a small amount of hydrogen gas is generated, water is gradually lost, and the liquid retaining liquid dries out. When this exceeds a certain limit, the internal resistance becomes significantly high and the discharge performance deteriorates. Therefore, in order to expect sufficient discharge performance in an emergency, it is necessary to constantly measure the dry and wet state of the liquid to manage the degree of deterioration of battery performance.

A sealed lead-acid battery comprising a porous body, two electrodes arranged so as to be in close contact with both sides of the porous body, and a circuit for measuring and indicating the electrical resistance between the two electrodes. be.

1 is the battery case and lid, 2 is the positive electrode plate, 3 is the negative electrode plate, 4
is a liquid-retaining material made of mats made of silicic acid gel, glass fiber, etc., and holds dilute sulfuric acid. Reference numeral 5 denotes a porous body which is partially in contact with the liquid retaining liquid 4, and is composed of a mat made of glass fiber or plastic fiber or a porous body. In order to bring the liquid-retaining material 4 and the porous body 5 into contact, if the liquid-retaining material is a porous material such as an ultrafine glass mat, the two may be partially overlapped and brought into close contact with each other. At this time, a portion of the liquid retaining liquid 4 may be made to protrude from the electrode plate group, and the protruding portion may be used as the porous body 5.

た。 If the liquid to be retained is a gel electrolyte, a portion of the porous body 5 may be buried in the gel electrolyte between the electrode plates and brought into contact with the gel electrolyte. At this time, in the case where a perforated plate is interposed between the electrode plates, a portion of the perforated plate may be made to protrude from the electrode plate group, and the protruding portion may be used as the porous body 5. Reference numerals 6 and 7 are two electrodes placed apart from the porous body 5 and in contact with the porous body 5, respectively. Reference numeral 8 is a power source for passing current through the electrodes 6 and 7, 9 is a circuit that measures and indicates the current or the voltage between the electrodes 6 and 7, and 10 is an exhaust section.
Note that straps, poles, and terminals are omitted.

てある。 Since a part of the porous body 5 is in contact with the liquid retaining liquid 4, the wet state of other parts of the porous body changes depending on whether the liquid retaining liquid becomes wet or dry. As shown in Figure 2, the relationship between this change in wet state and the electrical resistance increases significantly when the volume ratio of dilute sulfuric acid to the empty volume of the porous body reaches 0.7 and becomes drier.
In addition, FIG. 2 shows the case of a glass fiber mat having an average diameter of 0.5 μm as the porous body, and the case of a porous sheet made of polyethylene and fine silica powder.
多孔性体５の電気抵抗の測定には交流を用いる
とよい。直流では２つの電極６，７のうち片方が
陽極酸化、他方が陰極還元されてそれぞれ異なる
電位を示すため、多孔性体５を通して流れる電流

であれば２つの電極の電位が同じになるため、と
くに電圧を測定するのに好都合である。 It is preferable to use alternating current to measure the electrical resistance of the porous body 5. In the case of direct current, one of the two electrodes 6 and 7 is anodic oxidized and the other is cathodically reduced and exhibits different potentials, so errors are likely to occur in the measurement of the current flowing through the porous body 5 and the voltage across it. If it is an alternating current, the potentials of the two electrodes will be the same, which is particularly convenient for measuring voltage.
なお電極６，７に流れる電流を測定するには所
定の電圧を電極間に印加し、電圧を測定するには
所定の電流を流せばよい。 Note that in order to measure the current flowing through the electrodes 6 and 7, a predetermined voltage may be applied between the electrodes, and in order to measure the voltage, a predetermined current may be caused to flow.
本発明は以上のように、保液体の乾湿を測定す
ることにより電池を放電することなく、その劣化
程度を知ることを可能にしたものである。 As described above, the present invention makes it possible to determine the degree of deterioration of a battery without discharging the battery by measuring the wetness and dryness of the retained liquid.
