There are two types of applications: one in which batteries are repeatedly charged and discharged, and the other in which they are installed in an emergency power supply and used in a floating charging state, and methods for determining the lifespan depending on each application are known. In other words, for the former, the lifespan can be determined by measuring the change in terminal voltage during charging and discharging or by measuring the discharge capacity, but for the latter, it is prepared for emergency use, so method cannot be used, and the lifespan is determined by measuring the internal impedance. However, when used in a floating charging state, a commercial power supply is used as a charging source, and the charging current t obtained through a rectifier contains a rip/I/current of a commercial frequency component. Therefore, there is a drawback that the measurement current for measuring the internal impedance is affected by the ripple current described above, making the measurement value unstable.

ことにより、安定した測定値を得ることを目的とする。The present invention solves the above-mentioned drawbacks by adding the voltage measured by the internal impedance measuring device and the rifdel voltage due to the ripple current contained in the charging current, and using this added voltage to flow when the measuring voltage of the internal impedance measuring device is applied. The purpose is to obtain a stable measurement value by measuring the internal impedance of a lead-acid battery by dividing it by the measured current.

The internal impedance is determined by measuring the Lifdell voltage due to the ripple current caused by the ripple current, adding the measured voltage of the internal impedance measuring device to this fuglum voltage, and dividing this added voltage by the measuring current that flows when the measuring voltage of the internal impedance measuring device is applied. is calculated, and the lifespan is determined based on this calculated value.

When each is prepared one by one and put into an open state as shown in Figure 2,
As shown in Fig. 5, when a commercial power source 1, a rectifier 11!2, and a load 4 are connected to create a floating charging state, each lead-acid battery 5 has an AC constant voltage source 6-1 and an AC ammeter 6-2. When the internal impedance was measured by connecting an internal impedance measuring device 6 consisting of the above, applying a measuring voltage of 60H2 frequency and 1 mV of AC constant voltage, and reading the measured current with the AC ammeter 6-2, the internal impedance was determined as shown in Table 1. The following results were obtained. Note that for measurement in the floating charging state, before applying the measurement voltage, the +J contained in the charging current and the rifdel voltage due to the pull current are measured with the ripple voltage detector 5, and then the measurement voltage is applied and the AC ammeter 6 is used. The measured current was read at -2, and the internal impedance was measured by dividing the sum of the measured voltage and the Lifdell voltage by the measured current. Here, Q
