Abstract
The present invention relates to a device and a method for diagnosing a switch using voltage distribution, and more particularly, to a device and a method for diagnosing a switch using voltage distribution, which connect one or more resistors connected in series with the switch in parallel and calculate voltage applied to one resistor among one or more resistors by using the voltage distribution to diagnose a state of the switch based on the calculated voltage, in order to diagnose the state of the switch positioned on a cathode power supply line connecting a battery and a load.
