PURPOSE: A battery reproducer is provided to improve charging efficiency by supplying charging voltage having different frequency according to internal resistance of a battery and to reduce manufacturing costs of the battery reproducer. CONSTITUTION: A power supply unit(300) changes a common power source into a charging power source for regeneration of a battery. A circuit unit(400) has a switch in order to supply the charging power source to the battery. A main processor(100) controls the power supply unit and the circuit unit in order to supply the charging power source to the battery. The main processor determines frequency of the charging power source which is provided to the battery. The main processor controls the switch for the supply of the charging power source having the determined frequency of the charging power source. |
