Abstract

A battery diagnostic device and method are disclosed. The device includes: a measuring device to measure status values of a formed battery; a charge and discharge device to charge and discharge the battery over a plurality of cycles; and a control device to detect a discharge capacity in each cycle based on the status values measured in each cycle, detect an initial capacity increase amount of the battery based on a difference in discharge capacity between two cycles, detect a negative electrode undischarged capacity of the battery based on the discharge capacity in at least one cycle, and diagnose a formation status of the battery based on the initial capacity increase amount and the negative electrode undischarged capacity. Based on the diagnosis result, the control device is configured to invoke a second formation of the formed battery.
