Claim 0:
1. An apparatus for detecting overheating of a battery module, the apparatus comprising:
a battery pack including a first battery module and a second battery module;
a first temperature fuse arranged on the first battery module and having a first resistance value;
a second temperature fuse arranged on the second battery module and having a second resistance value;
a third temperature fuse spaced apart from the first and second battery modules and having a third resistance value;
wherein the first, second, and third temperature fuses are connected to each other in parallel;
a storage configured to store a reference table in which a reference resistance value is recorded corresponding to disconnection of at least one of the first temperature fuse, second temperature fuse, or the third temperature fuse; and
a controller configured to:
detect an overheated battery module based on a total resistance value of the first, second, and third temperature fuses, and the reference table; and the reference table; and
determine that a defective connector connection has occurred on connection line between the first, second, and third temperature fuses and the controller when the total resistance value of the first, second, and third temperature fuses is 0Ω.
