Claim 0:
1. A battery module composed of a plurality of battery cells, the battery module comprising:
one positive output terminal connected to the plurality of battery cells;
one negative output terminal connected to the plurality of battery cells;
a field effect transistor (FET) provided on a current path between the positive output terminal and an external device;
a temperature information measurer configured to measure temperature information of the plurality of battery cells; and
a protection integrated circuit (IC) chip configured to control the FET, wherein the protection IC chip comprises:
a temperature calculation module configured to calculate a temperature of each of the plurality of battery cells based on the temperature information received from the information measurer;
a grouping module configured to generate a first temperature group of at least two adjacent battery cells among the plurality of battery cells;
an average temperature calculation unit configured to calculate an average temperature of the battery cells included in the first temperature group; and
a high temperature determination unit configured to determine whether a temperature of the battery module is above a predetermined temperature based on the calculated average temperature of the first temperature group.
