Abstract

A battery diagnosis device includes a temperature detector configured to detect temperatures of battery cells. An impedance detection device is configured to generate an AC current signal flowing through the battery cells, detect an AC voltage signal corresponding to the AC current signal for each of the battery cells, and detect impedance data of each of the battery cells based on the AC current signal and the AC voltage signal. A controller is configured to activate or deactivate the impedance detection device according to a temperature deviation of the battery cells and detect an abnormal cell among the battery cells based on the impedance data when the impedance detection device is activated.
