BATTERY MANAGEMENT APPARATUS AND METHOD

The present invention relates to a battery management apparatus that includes a temperature sensor configured to measure a temperature for each section of each battery cell included in a battery module, a heat management module configured to control a temperature of the battery cell or the temperature for each section of each battery cell, and a processor, wherein the processor is configured to calculate a maximum average slope value (gCell1 to gCellN) for each battery cell which is a maximum value among a plurality of average temperature slopes for respective sections of each battery cell, wherein the maximum average slope value corresponds to a maximum value among a plurality of average temperature deviations with nearby sections for respective sections of each battery cell, and perform temperature control or charging current control in a specific manner on a weak battery cell based on the maximum average slope values (gCell1 to gCellN) of a plurality of battery cells.
