摘要： An impedance measuring device outputs an alternating current of a prescribed frequency to each of a positive electrode terminal and a negative electrode terminal of a laminated type battery and detects an alternating-current potential difference between the positive electrode terminal and an intermediate-point terminal and an alternating-current potential difference between the negative electrode terminal and the intermediate-point terminal. The impedance measuring device adjusts an amplitude of the alternating current such that the alternating-current potential difference between the positive electrode terminal and the intermediate-point terminal and the alternating-current potential difference between the negative electrode terminal and the intermediate-point terminal coincide, and computes an impedance on the basis of the adjusted alternating current and alternating-current potential differences. Then, the impedance measuring device corrects a phase difference of the alternating currents output to the positive electrode terminal and the negative electrode terminal on the basis of a phase difference between an alternating-current potential generated at the positive electrode terminal and an alternating-current potential generated at the negative electrode terminal.

摘要： An impedance measuring device includes power supply means configured to output an alternating current to a positive electrode and a negative electrode of a laminated battery and detection means configured to detect at least one of an alternating-current potential difference between the positive electrode and an intermediate point of the laminated battery and an alternating-current potential difference between the negative electrode and the intermediate point of the laminated battery. The impedance measuring device includes computation means configured to compute an impedance of the laminated battery on the basis of the alternating-current potential difference detected by the detection means and the alternating current output from the power supply means, and an element having an impedance of a prescribed value necessary to calculate a measurement error of the impedance. The impedance measuring device includes switch means configured to alternately switch a battery connection state for connecting the power supply means and the detection means to the laminated battery and an element connection state for cutting off connection to the laminated battery and connecting the power supply means and the detection means to the element. The computation means computes an impedance of the element and diagnoses a measurement state of the laminated battery or corrects the impedance of the laminated battery when the switch means is switched to the element connection state.
