Claim 9:
10. A battery management system circuit, comprising:
a substrate;
a first resistor part disposed on the substrate and including a plurality of resistors;
a first perforation formed by piercing the substrate at a position corresponding to a first surface of the first resistor part; and
a first thermal pad attached to a plurality of resistors included in the first resistor part; and
a third thermal pad attached to an upper surface of the first resistor part,
wherein the first resistor part is spaced from the second resistor part and the first perforation in a horizontal direction parallel to the substrate,
wherein the first resistor part does not overlap the first perforation,
wherein the first perforation is configured to diffuse heat generated in the first resistor part, and
wherein the third thermal pad, while penetrating through the first perforation, is wound at least once around the first resistor part and a lower surface of the substrate.
