A united BMS(Battery Management System) and DC/DC converter is provided to reduce a volume and a weight and to improve efficiency by integrating an overlapped part of a BMS and a DC/DC converter. A united BMS and DC/DC converter includes a battery information sensing unit, a microprocessor(10), a pre-charging and disconnecting switch control unit(18). The battery information sensing unit senses voltage, current, and temperature of a battery. The microprocessor receives a sense signal from the battery information sensing unit, exchanges information with a motor control unit through a CAN(Controller Area Network), and controls on and off of a precharge relay and a relay connecting the battery. The pre-charging and disconnecting switch control unit receives a control signal from the microprocessor and supplies power to the motor control unit.
