Abstract

A battery system includes: a battery; a resettable fuse that is connected between a first node connected to a positive electrode of the battery and a second node connected to an external connection end and is closed after a predetermined recovery time after the resettable fuse is opened; a fuse compensation circuit that includes an operation switch connected between the first node and the second node and a sensing switch connected between a third node to which a voltage is provided according to a result of comparing a voltage of the second node with a predetermined reference voltage and ground and generates a first sensing voltage by resistance distribution of the voltage of the second node; and a main control unit (MCU) that controls a switching operation of the sensing switch based on the first sensing voltage. The fuse compensation circuit controls a switching operation of the operation switch according to a second sensing voltage according to a voltage of the third node.
