Abstract
An internal resistance measurement device for stacked battery includes an AC power supply part for outputting an AC current to an measurement-object, which includes at least a stacked battery made of a plurality of stacked power generating elements, by being connected to the measurement-object, an AC adjusting part for adjusting an AC current so that a positive-electrode AC potential difference, which is a potential difference obtained by subtracting potential in a middle portion from potential in a portion connected to a load device on the positive side of the measurement-object, matches a negative-electrode AC potential difference, which is a potential difference obtained by subtracting potential in the middle portion from potential in a portion connected to the load device on the negative side of the measurement-object, and a resistance calculating part for calculating resistance of the battery based on the adjusted AC current and the AC potential difference.
