Abstract

A driving control device (100) for a relay for a battery pack, includes: a buck-boost converter (110) to receive a voltage from an auxiliary battery (VL), and output a buck-boost voltage (Vout); a feedback control circuit (120) electrically connected to the buck-boost converter (110), and to transfer a feedback voltage (Vf) to the buck-boost converter (110) to control the buck-boost voltage (Vout) output from the buck-boost converter (110); and a relay control circuit (140) to apply or block the buck-boost voltage (Vout) 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 (110) is to output the buck-boost voltage (Vout) according to the feedback voltage (Vf), and the buck-boost voltage (Vout) has a smaller sustaining voltage for maintaining the relay in an on state than a first reference voltage for turning on the relay.
