Battery control system for preventing cell imbalance and operating method thereof

A battery control apparatus connected with a temperature measuring device configured to measure a temperature of a first battery cell disposed at a first point among a plurality of battery cells included in a battery assembly and a temperature of a second battery cell disposed at a second point among the plurality of battery cells, wherein the second point is apart from the first point, the battery control apparatus comprising:

• at least one processor;
• and
• a non-transitory memory configured to store at least one instruction executed by the at least one processor,
• wherein the at least one instruction includes:
• an instruction to monitor the temperature of the first battery cell and the temperature of the second battery cell;
• and
• an instruction to perform a predefined control operation for preventing state degradation due to temperature imbalance between the plurality of battery cells based on at least one of the temperature of the first battery cell and the temperature of the second battery cell.
