Description of the Related Art Liquid lead-acid batteries for automobiles and the like have been checked for their condition by measuring the specific gravity of the electrolyte, but the specific gravity is measured by opening the battery and taking out a small amount of the electrolyte. , I couldn't measure easily at a battery shop or a gas station. Also, the starting performance of the lead acid battery for automobiles was measured by flowing a large current for several seconds and measuring the voltage at the fifth second, but since it was measured at a current exceeding 100A, it could not be measured as easily as the specific gravity measurement. It was limited to inspections at specialized vehicle inspection stations. Further, the battery capacity is measured by discharging an actual battery with a specified current for a specified time. Therefore, the test time includes 20 hours or more including the charging time, and there is a drawback that the tester is restrained for a long time.

In the method of judging the starting performance of the battery from the second voltage etc., a large clip with a pseudo load is connected to the battery terminal, so the large clip was accidentally removed from the battery terminal during short-time discharge. In that case, there is a risk that sparks may be generated and burn the human body. In addition, if a test is conducted immediately after the end of charging, there is a risk of explosion if sparks are generated. Therefore, in terms of safety, the shorter the short-time discharge time is, the better. However, in an extremely short time, the transient voltage fluctuation at the time of discharge is affected by the inductance component of the wiring, which is not related to the starting performance of the battery and the capacity deterioration, and there arises a problem that accurate measurement cannot be performed.

The current battery capacity is obtained by substituting the differential voltage or the internal resistance of the battery into a regression equation of the battery capacity or the fifth-second voltage of the lead storage battery and the differential voltage or the internal resistance of the battery. Alternatively, the fifth voltage is estimated.

In the lead storage battery deterioration determination method of the present invention, in the lead storage battery, the differential voltage between the battery voltage before energization and the battery voltage in a stable state after short-time energization has a strong correlation with the current battery capacity and the fifth-second voltage, Also, the stable state of the battery voltage is 200 μsec.
Paying attention to the fact that the voltage reaches in the above condition, the current battery capacity and the starting performance are estimated with high accuracy from the relationship between the voltage of the difference of the energization characteristics of 200 μsec to 1 msec, the battery capacity, and the voltage at the fifth second. By setting the test time to 1 msec or less as described above, even if the battery and the tester are accidentally separated from each other, there is no fear that a spark will be generated due to the end of energization, and safety is improved.

FIG. 2 is a diagram showing short-time discharge characteristics of a new lead battery and a deteriorated lead storage battery. FIG. 3 is a diagram showing an equivalent circuit model of the short-time discharge characteristic of the battery. In the equivalent circuit of FIG. 3, 7 is a battery voltage V B , 8 is a liquid resistance R 1 including an electrode internal resistance, 9 is a charge transfer resistance R 2 , 10 is an electric double layer capacitor C, and 11 is a current equivalent to a discharge current. I, 12, 13 are battery terminals. When the voltage across the electric double layer capacitor 10 is V C and the voltage V (t) between the battery terminals 12 and 13 at the time of short-time discharge is obtained from FIG. 3, it is as follows.

(1) (1) When the stable state (t → ∞) is calculated from the equation), V (t) = V B −I · (R 1 + R 2 ) is obtained. Letting ΔV (FIG. 2) be the difference voltage between the battery voltage V B before discharge and the battery terminal voltage V (t) in the stable state after discharge, ΔV = V B −V (t) = I · (R 1 + R 2 )… (2) As the deterioration of the battery progresses, the liquid resistance R 1 including the electrode internal resistance and the charge transfer resistance R 2 also increase, so that the voltage ΔV of the difference in the equation (2) increases.
