Device For Estimating Battery Condition
Abstract: A device for estimating a battery condition according to one embodiment of the present invention comprises: a voltage measuring unit configured to measure a voltage of a battery cell and measure an open circuit voltage of the battery cell whenever the measured voltage reaches a reference discharge voltage; and a control unit configured to receive the open circuit voltage measured by the voltage measuring unit, compare the received open circuit voltage with a pre-stored reference voltage to calculate voltage regulation, determine a voltage increase/decrease pattern on the basis of the calculated voltage regulation and pre-stored voltage regulation data, and determine an acceleration degree of deterioration of the battery cell according to the determined voltage increase/decrease pattern.
