Claim 8:
9. A method for detecting whether there is a high temperature of a battery module, the method comprising:
an individual battery cell temperature measurement step of measuring a temperature of each of a plurality of battery cells constituting the battery module;
a grouping step of generating a first temperature group of at least two adjacent battery cells among the plurality of battery cells;
a group specific average temperature calculation step of calculating an average temperature of battery cells for the first temperature group;
a high temperature determination step of determining whether a temperature of the battery module is above a predetermined temperature based on the calculated average temperature for the first temperature group; and
a battery module charging/discharging blocking step of turning off a field effect transistor (FET) of the battery module and blocking charging or discharging of the battery module in response to determining that battery module is above the predetermined temperature in the high temperature determination step.
