PURPOSE: A charge and discharge system of a battery pack is provided to maintain stable current balancing between current generating modules and obtain current precision of high current. CONSTITUTION: A current generating circuit part(110) comprises a plurality of current generating circuits. A power transmission part distributes power and delivers the power to the current generating circuits. A first current sensing circuit part(130a) detects the output current of each current generating circuit. A second current sensing circuit part(130b) detects the output current of the whole current generating circuits. A current control circuit part(150) controls each current generating circuit to maintain current balancing between the current generating circuits.
