る方式が採用されている。2. Description of the Related Art Heretofore, a method of measuring the internal impedance has been attempted as one of the methods for determining the state of a lead storage battery. In general, a device for measuring the internal impedance uses two sets of measuring probes, one pair of contacts for supplying a measuring current and one pair of contacts for detecting a voltage, because the internal impedance of a lead-acid battery is very small. A method based on the AC four-terminal method has been adopted.

流をカットできないために直流結合となるためである。However, when measuring the internal impedance at the above low frequency, if the connection between the measuring instrument and the storage battery is incorrect, the alternating current cannot be supplied normally and the normal measurement cannot be performed. The measuring instrument has a possibility of failure. This is because the connection frequency between the current-carrying portion of the alternating current and the storage battery cannot be cut off by using a capacitor because the current-carrying frequency is low.
