PURPOSE: A feedback voltage sensing apparatus for charger is provided to control accurately and safely a charging voltage supplied to a battery by sensing feedback voltages and providing the detected feedback voltages as a feedback control information. CONSTITUTION: When a battery(1) of a feedback voltage sensing apparatus is charged with a voltage(V1) from a charger(2), the voltage(V1) from the charger(2) is detected and analyzed by resistances(R1,R2) and then supplied to a feedback controller(3) via a diode(D1). A charging voltage from the battery(1) is detected and analyzed by resistances(R3,R4) and supplied to the feedback controller(3) via a diode(D2). The voltage from the charger(2) is accurately controlled according to a controlling operation of the feedback controller(3) which is supplied with the feedback detection voltage from the diodes(D1,D2). It is preferable that voltage sensing points of the resistances(R1,R2) are distanced from the charger(2) for correct detection.
