Beschreibung
Zusammenfassung:	A battery impedance measuring device includes a connection circuit unit that includes a terminal detachable from a charging terminal for charging a secondary battery, a terminal detachable from a charging terminal for charging the secondary battery, a first capacitor connected to the terminal, and a second capacitor connected to terminal, and a main body unit that includes an AC signal supply unit that supplies an AC signal to the secondary battery via the first and second capacitors, and a measurement unit that detects at least one of a signal obtained from the secondary battery via the terminal and the first capacitor and a signal obtained from the secondary battery via the terminal and the second capacitor and measures impedance of the secondary battery based on the detected signal.
