Abstract
The present invention relates to a relay driving circuit and a battery system for generating a gate voltage for controlling ON/OFF of a pre-charge relay, and provides a relay driving circuit that controls electrical connection between an external device and a battery pack, including: a transistor that receives a control signal of an enable level to perform an ON operation; a first resistor having a first end connected to a positive electrode of the battery pack and a second end connected to the relay, by the ON operation of the transistor; and a second resistor connected between the second end of the first resistor and the external device, the relay receives power supplied from the battery pack in a ratio of a resistance value of the second resistor to a sum resistance value of the first resistor and the second resistor to perform an ON operation.
