Related Art and its Problems Conventionally, in order to determine the life of an open-type lead-acid battery, specific judgments have been made by measuring specific gravity or visually observing the appearance. However, in the sealed lead-acid battery, the above-mentioned method used in the open lead-acid battery cannot be used, and the life cannot be known. For this reason, various methods have been developed to determine the lifetime by detecting changes in the charge / discharge voltage, changes in the internal impedance, and the like.However, when an accurate determination cannot be made depending on the life factor or when a different value is used depending on the determination method. It was not reliable as shown. For example, in the above-described method of detecting a change in the internal impedance to determine the life, there is almost no difference in the internal impedance between a new product and a life product depending on the measurement frequency, and thus the life is difficult to determine.

を示す。First, before implementing the method of the present invention, a unique resonance frequency determined by the structure, dimensions, and the like of the lead storage battery was determined. New sealed sealed lead-acid battery (MSE-200, 200Ah / 10HR, 2V) and high-temperature float life test (test temperature 45 ° C, float voltage 2.23V /
Cells), each of which has reached the end of its life, 2 cells each, for a total of 4
Each battery was prepared, an AC constant current of 100 mA was passed through an AC four-terminal measuring circuit shown in FIG. 1, and the measurement frequency was varied from 1 Hz to 10 KHz to measure the internal impedance of the battery. The result is shown in FIG. Further, the phase difference between the measurement current and the measurement voltage at each measurement frequency was measured with an oscilloscope. FIG. 3 shows the results. FIG. 1 is a wiring diagram of an AC four-terminal circuit in which a battery 2 to be measured is connected to an internal impedance measuring instrument 1 comprising an AC constant current source 1-1 and an AC voltmeter 1-2.

From the results shown in the figure, it was found that the phase difference between the voltage and the current was 0 ° around the frequency of 60 Hz. Thus, assuming that the internal impedance of the battery is R for pure resistance, L for inductance, C for capacitance, and ω for angular frequency,
= R + j (ωL−1 / ωC), where ωL = 1 / ωC
= R (resonance frequency)
Since the internal impedance is minimized and the phase difference between the measured current and the measured voltage is also 0 °, it was found that the resonance frequency was around 60 Hz.
