【発明の詳細な説明】 産業上の利用分野 本発明は比１θセンサー付密閏形鉛電池に関する。[Detailed description of the invention] Industrial applications TECHNICAL FIELD The present invention relates to a closed-circuit lead-acid battery with a ratio 1θ sensor.

知ることができる。BACKGROUND ART AND PROBLEMS As is well known, the charging and discharging status of a lead-acid battery can be accurately determined by measuring the specific gravity of the electrolyte. This is because the change in specific gravity of the electrolyte corresponds to the change in capacity (chemical reaction amount) of the battery, and the release 'R1
! This is because it decreases in proportion to the amount of energy. Therefore, by measuring the specific gravity of the electrolyte, you can tell how much the battery is being discharged, or how much 8i is remaining! It is possible to accurately know whether the discharge is possible or not.

限られている。However, since sealed lead batteries do not have a fluid electrolyte, they cannot use the specific gravity sensors that apply buoyancy or changes in refractive index, which are used in conventional open lead batteries. The current practical specific gravity sensor is Pb0z P
This method is limited to a method in which a pair of b electrodes is inserted into the lifm of a battery and the electromotive force of this electrode pair is measured, which changes depending on the specific gravity of the electrolyte.
密閉形鉛電池は開口できないため一度組込んだ比重セン
サーは取替えができず寿命の長いことが不可欠な条件で
ある。Sealed lead-acid batteries cannot be opened, so the specific gravity sensor once installed cannot be replaced, so a long life is essential.

電電流の増加はセンサーのＰｂ Ｏ２極の集電体を激し
くｉ食し、寿命が短くなるという欠点があった。The structure of a sealed battery limits the amount of electrolyte and uses a separator with good gas permeability. During charging, the oxygen gas generated from the positive plate reacts with the lead on the negative plate, which is the so-called oxygen cycle, which reduces the amount of electrolyte. It's suppressed. Therefore, since the inside of this battery is in an oxygen atmosphere as the temperature rises due to the reaction between lead and oxygen, the r'bWi of the sensor
The poles have a high self-discharge and must be charged with a higher current than conventional open lead batteries. On the other hand, an increase in the charging current has the disadvantage that the current collector of the PbO2 electrode of the sensor is severely eaten away, resulting in a shortened lifespan.
