PURPOSE: A power source driving circuit at the battery management system is provided to control a cell balancing operation or a battery managing function by a jumper in a state in which an ignition signal or a wakeup signal is not applied. CONSTITUTION: A power source driving circuit(200) comprises a connector(210) for connecting to a battery cell, a first switching part(220) which switches a source applied from the battery cell through the connector, and a second switching part(250) which turns on the power source. The first switching part applies a power source to a photo coupler(230) according to an ignition signal or a wakeup signal. A controller(240) controls a battery managing function including a cell balancing operation. The first switching part is composed of FET(Field Effect Transistor). The second switching part is composed of an NPN type transistor.
