According to one embodiment of the present invention, provided is a failure diagnosis circuit of a battery management system, which comprises: a first line including a first resistor, one end of which is connected to a positive pole of a battery, and the other end of which is connected to a first input unit of an analog to digital converter (ADC); a second line including a second resistor, one end of which is connected to a positive electrode of the battery, and the other end of which is connected to a first input unit of a comparator; and a third line including a third resistor, one end of which is connected to the negative pole of the battery, a first the other end of which is connected to a second input unit of the ADC, and a second the other end of which is connected to a second input unit of the comparator. According to the present invention, a failure of the battery management system can be efficiently diagnosed with fewer elements.
