摘要： PURPOSE: A high capacity battery charger for battery production and a charger-discharger are provided to prevent safety accidents by cutting off charging and discharging operations in the case of an abnormal unbalanced situation. CONSTITUTION: An AC power supply is inputted in a power input unit(10). A charge driving unit(20b) rectifies the AC power supply into a DC power supply. A power detection unit detects voltage and current of a plurality of batteries in real time. A controller(40) controls the operation of the power input unit and the charge driving unit according to the voltage and the current detected in the power detection unit. A voltage acquisition unit obtains an output voltage of the charge driving unit in the on-state of a silicon controlled rectifier. An unbalanced output sensing unit(50) comprises a sensing signal generating unit. The sensing signal generating unit creates a sensing signal for cutting off the operation of the charge driving unit and transmits it to the controller.
