Disclosed are an intelligent battery sensor and a method for estimating the normal capacity of a battery in the intelligent battery sensor. The method for estimating the normal capacity of a battery according to an embodiment of the present invention comprises a first step for calculating a first charging state change amount (first SOC change amount) calculated by accumulating current amount of the battery according to car driving between a first time point and a second time point when the battery of a car is stabilized; a second step for calculating a second charging state change amount (second SOC change amount) by using the difference of the open circuit voltage of both ends of the battery in the first time point and the second time point; and a third step for comparing the difference (change amount difference) between the first SOC change amount and the second SOC change amount with a predetermined threshold error value and estimating the normal capacity of the battery based on a comparison result. |
