A relay control apparatus according to the present disclosure is for a relay including a contact connected between a positive electrode of a battery and a load; and a coil connected between a relay power terminal and a ground wherein the contact moves to a closed position when the coil is energized. The relay control apparatus includes a coil control switch which is turned on in response to a first switching signal having a voltage level that is equal to or higher than a first threshold voltage in response to a relay on-command; and a relay holding circuit configured to store emergency power using power supplied from the battery.
