Forecasting the end of the service life of a relay more accurately due to the effects of the load conditions and the environmental conditions can occur through diagnosing the end of service life of the relay based on the time, until the point in time that the actual opening or closing of the relay is detected, from the point in time of the application of the power to the relay or the point in time of the end of application of power to the relay coil by the controlling portion. Forecasting the end of the service life of the relay based on time, increases accuracy because time is a value that is not affected by the external environment. Additionally, because the end of the service life is forecasted based on the actual opening/closing of the relay, not only is it possible to detect immediately a fault in the relay, but it is also possible to eliminate the effects due to individual differences.
