Provided is a method of estimating the state of health of the battery according to various embodiments. The method of estimating the state of health of the battery comprises: measuring a voltage and current of a battery in use to periodically generate a voltage value and a current value; using an adaptive filter to periodically update a G parameter value and an H parameter value in real time from the voltage value and the current value, said parameters indicating the present state of the battery; and using an initial value and a final value of the G parameter that is preset and a present value of the G parameter to estimate the state of health of the battery in real time. The G parameter is a parameter that represents the sensitivity of the voltage to changes in the current of the battery, and the H parameter is a parameter that represents an effective potential determined by the local equilibrium potential distribution and resistance distribution inside the battery.
