Disclosed are an arc extinguishing control system and method for a relay of an emergency power supply. A relay serves as a main switching circuit for controlling an emergency power supply, and electronic switching tubes are connected in parallel to two ends of the relay, so as to withstand a voltage jump when the relay is disconnected, and common problems of existing relays, such as arc damage and an internal resistance increase, are solved. When a heavy reverse charging current occurs after the vehicle is started, a reverse charging sensing circuit and a reverse charging feedback circuit are used, so that a reverse charging current is directly fed back to a control end of an electronic switching tube when a storage battery is reversely charged by a load, thereby realizing quick disconnection of the electronic switching tube.
