Apparatus and method for managing battery

A battery managing method comprising:

• a voltage measurement step of measuring a voltage of a battery that is charged by repeating a charging period and a resting period;
• a resistance calculation step of calculating a resistance of the battery corresponding to each of a plurality of resting periods;
• a profile generation step of generating a first profile indicating a correspondence relationship between a state of charge (SOC) and the resistance of the battery;
• a SOC section division step of dividing a SOC section of the first profile into a plurality of unit sections;
• and a summed resistance calculation step of calculating a summed resistance of the battery based on a weight and a resistance corresponding to each of the plurality of unit sections, wherein an entire resistance for the SOC section and a unit resistance for each of the plurality of unit sections are calculated, and the weight corresponding to each of the plurality of unit sections is calculated based on the entire resistance and the plurality of calculated unit resistances.
