Abstract
A jig for impedance measurement of a battery cell includes: a jig body configured to receive a battery cell in a longitudinal direction; a first bus bar installed on a first side of the jig body, the first bus bar being configured to couple to a first lead part of the battery cell; a second bus bar installed on a second side of the jig body, the second bus bar being configured to couple to a second lead part of the battery cell; an impedance measuring board in the jig body; and a conducting line for impedance measurement connecting the first bus bar, the impedance measuring board, and the second bus bar to constitute an impedance measuring circuit. A part of the conducting line for impedance measurement faces a surface of the battery cell and extends in the longitudinal direction of the battery cell.
