Abstract: 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.

Abstract: A hybrid current sensor assembly has a conductor, Hall core, Hall sensor, shunt terminal, and a microprocessor. The conductor has a first terminating end and a second terminating end. The Hall core generates a magnetic field from current flow in the conductor. The Hall sensor measures potential difference between first terminating end and the second terminating end of the conductor based on the magnetic field applied to the Hall core. The shunt terminal is positioned on a central portion of the conductor. The microprocessor is connected to the shunt terminal to measure the current flow in the conductor.
