DRIVING CONTROL DEVICE OF RELAY FOR BATTERY PACK

A driving control device for a relay for a battery pack, includes: a buck-boost converter to receive a voltage from an auxiliary battery, and output a buck-boost voltage; a feedback control circuit electrically connected to the buck-boost converter, and to transfer a feedback voltage to the buck-boost converter to control the buck-boost voltage output from the buck-boost converter; and a relay control circuit to apply or block the buck-boost voltage to a relay electrically connected to at least one of a positive electrode terminal or a negative electrode terminal of a main battery. The buck-boost converter is to output the buck-boost voltage according to the feedback voltage, and the buck-boost voltage has a smaller sustaining voltage for maintaining the relay in an on state than a first reference voltage for turning on the relay.
