発明が解決しようとする課題
しかし、上記の検知方法では、シール鉛［６の劣化要因
によっては検知不可能であるという課題を有している。Problems to be Solved by the Invention However, the above detection method has a problem in that detection is impossible depending on the deterioration factor of the seal lead [6].
シール鉛電池の劣化要因は、電解液の減少、陽極格子の
伸び（腐食）の２つに大別される。The causes of deterioration of sealed lead batteries can be broadly divided into two: decrease in electrolyte and elongation (corrosion) of the anode grid.

流の明らかな増大は認められず、上記検知方法を適用す
ることは不可能であった。As shown in Figures 3 and 4, when the life is reached due to elongation (corrosion) of the anode lattice, the charging current increases at the end of the life, but when the life is reached due to a decrease in electrolyte No obvious increase in the charging current was observed, making it impossible to apply the above detection method.
課題全解決するための手段
本発明は上記の課題を解決するためになされたもので、
シール鉛電池に９．流電流成分を含む充電を流を一定時
間通電した時点で、シール鉛電池の電池電圧に含まれる
交流電圧成分と直流電圧成分を測定した値により劣化状
態を検知することを特徴とするものである。Means for solving all the problems The present invention has been made to solve the above problems,
9. Sealed lead battery. The battery is characterized by detecting the deterioration state based on the measured values of the AC voltage component and the DC voltage component included in the battery voltage of the sealed lead-acid battery at the time when a current including a current component is passed through the battery for a certain period of time. .

寿命が検知でき、又、陽極格子の伸び（腐食）で寿命と
なった場合にｉｌ′１ｔａｔ圧に含まれる直流電圧が正
常晶に比べて増大するため、寿命と検知できる。Operation The present invention has the above-mentioned characteristics, so that when the sealed lead 1 battery reaches the end of its life due to a decrease in electrolyte, the AC voltage component included in the battery voltage increases compared to a normal crystal. ,
The lifetime can be detected, and when the anode lattice reaches the end of its life due to elongation (corrosion), the DC voltage included in the il'1tat pressure increases compared to that of a normal crystal, so the lifetime can be detected.

極格子の伸び（腐食）により陽極格子と陽極活物質の密
着が悪化するため、相対的な充電電流密度の増大により
充電過電圧が増大したためと考えられる。When a sealed lead-acid battery reaches the end of its life due to a decrease in electrolyte, the AC voltage component included in the battery voltage increases compared to a normal crystal because the adhesion between the separator and the electrode plate deteriorates due to the decrease in electrolyte. However, this is due to an increase in internal resistance, and the reason why the DC voltage component included in the battery voltage increases compared to a normal crystal at the end of its life due to elongation (corrosion) of the anode lattice is due to elongation (corrosion) of the anode lattice. ), which deteriorates the adhesion between the anode lattice and the anode active material, which is thought to be due to an increase in charging overvoltage due to an increase in relative charging current density.
