Abstract
A battery diagnostic device according to one embodiment of the present document may include: an interface for obtaining an impedance according to the frequency of a voltage applied between each of a plurality of measurement points of a first electrode lead of a battery cell to be tested and a second electrode lead of the battery cell; and one or more processors for diagnosing the state of the battery cell based on a first impedance, which is an impedance between a first point among the plurality of measurement points and the second electrode lead; a second impedance, which is an impedance between a second point among the plurality of measurement points and the second electrode lead; and a first impedance change amount, which is a difference value between the first impedance and the second impedance.
