A lithium precipitation detecting apparatus according to an embodiment of the present disclosure includes a measuring unit configured to calculate a charge amount of a battery in a charging process and calculate a discharge amount of the battery in a discharging process; and a control unit configured to estimate a state of charge (SOC) of the battery in the charging process and the discharging process and determine whether lithium precipitation occurs in the battery based on the estimated SOC, the charge amount and the discharge amount.

Lithium precipitation detecting apparatus and method

A battery diagnosis apparatus according to the present disclosure includes a voltage measurer for measuring a cell voltage of each of first to nbattery cells and a processor, wherein n is a natural number of 2 or greater. The processor determines an average cell voltage of each battery cell for a first rest period from a first time point to a second time point, based on the cell voltage of each battery cell measured a first number of times for the first rest period, determines an average cell voltage of each battery cell for a second rest period and diagnoses a fault of each battery cell based on the average cell voltage of each battery cell for the first rest period and the average cell voltage of each battery cell for the second rest period.
