摘要： The present invention provides a battery monitoring method, which is performed by a battery monitoring device, including: measuring a first voltage drop across both ends of a first shunt resistor of a bus bar electrically connected to a battery and a second voltage drop across both ends of a second shunt resistor, which is in parallel or serial connection with the first shunt resistor; calculating a first current and a second current flowing, respectively, through the first shunt resistor and the second shunt resistor using a first voltage drop value and a second voltage drop value; and determining a state of the battery using a difference between a first current value and a second current value. According to the present invention, it is possible to increase the reliability of monitoring information related to the battery's state by utilizing current values that have undergone linearity compensation and temperature compensation.
