The invention discloses a system and method for measuring battery impedance spectroscopy. In the system for measuring battery impedance spectroscopy, a phase-locking amplifier is configured to generate a voltage excitation signal and measure response voltage signals of both ends of the battery, so as to acquire the amplitude and the phase of the response voltage signal; one end of a voltage-current conversion circuit is connected with the phase-locking amplifier, and the other end is connected with the battery; the voltage-current conversion circuit converts the voltage excitation signal intosame-frequency current excitation signal so as to input the same-frequency current excitation signal into the battery; one end of a direct-current voltage compensation circuit is connected with the battery, and the other end is connected with the phase-locking amplifier; the direct-current voltage compensation circuit removes the direct-current bias in the response voltage signal and amplifies theresponse voltage signal so as to input the response voltage signal into the phase-locking amplifier; a processor is connected with the phase-locking amplifier; and, the processor sweeps the frequencyof the phase-locking amplifier and records the amplitude and the phase of the response voltage signal so as to generate the electrochemical impedance spectrogram of the battery.
