Abstract
A system of predicting a failure rate of a contactor before the generation of a failure by counting a lifespan index of the contactor based on normality of through-currents of a primary side and a secondary side of the contactor, and determining that a failure rate of the contactor increases when a count value for an abnormal through-current exceeds a predetermined threshold value.
