PURPOSE: An apparatus for detecting a charge/discharge state signal of a contactless charge system and a control method thereof are provided to prevent malfunction of a battery cell in advance by detecting a change of inner resistance of the battery cell. CONSTITUTION: A transmitting state signal processing module(32) transmits a transmitting state signal of a power transmitting device(10) to a detecting control part(31). A transmitting control signal processing module(33) transmits a control signal of the detecting control part to a power supply module of the power transmitting device. A charging state signal processing module(34) is connected to a charge module of a power receiving device(20). The charging state signal processing module transmits a state signal of the power receiving device to the detecting control part. A power discharge module(35) is connected to a battery cell of the power receiving device. The power discharge module discharges the battery cell of the power receiving device according to a control signal of the detecting control part. |
