Abstract
An apparatus for measuring an impedance of a laminated battery includes a laminated battery in which a plurality of power generating elements is laminated; a load connected to both ends of the laminated battery; a resistance component provided between the superimposing unit and the load; and a potential difference suppressing circuit that suppresses a pulsating potential difference between both ends of the resistance component. A superimposing unit superimposes a pulsating current or a pulsating voltage on an output of the laminated battery. An impedance measuring unit measures an internal impedance of the laminated battery on the basis of when the pulsating current is superimposed, the pulsating current and a pulsating voltage generated by superimposing the pulsating current, or on the basis of, when the pulsating voltage is superimposed, the pulsating voltage and a pulsating current generated by superimposing the pulsating voltage.
