Abstract: PURPOSE: A method and a device for measuring the impedance of an electrochemical device are provided to easily confirm influence of a parameter of an equivalent circuit on a track of a nyquist plane by supplying a real-time manual fitting function. CONSTITUTION: A detection and conversion device(300) detects the voltage and current variation of an electrochemical device(100). A DAQ board(400) is comprised of a two channel analog/digital converter and a two channel digital/analog converter. The two channel analog/digital converter and the two channel digital/analog converter convert the voltage and current detected from the detection and conversion device into a digital signal. A digital locking-in amplifier(500) calculates the impedance spectrum of the digital current and voltage for each frequency outputted from the DAQ board. An equivalent circuit fitting unit(600) fits the result calculated by the digital lock-in amplifier to an equivalent circuit. A perturbation signal generator(700) controls a power amplifier(200) to obtain the voltage or current overlapped with a perturbation component in a DC component from the electrochemical device. A central processor(800) controls the digital lock-in amplifier, the equivalent circuit fitting unit and the perturbation signal generator.
