Zusammenfassung:	A battery charging and discharging test apparatus according to the present embodiment includes a plurality of test modules electrically connected to each other, wherein each of the test modules includes a controller for controlling a DC voltage generator and a DC voltage generator and provides a DC voltage, and an operation part for calculating and providing the average voltage value of DC voltages provided by the plurality of test modules. The control part calculates a voltage offset corresponding to a difference between the average voltage value and the DC voltage provided by the operation part and controls the voltage value of the DC voltage to correspond to the average voltage value. It is possible to reduce voltage deviation. 본 실시예에 의한 배터리 충방전 시험 장치는, 상호 전기적으로 연결된 복수의 테스트 모듈로, 각각의 테스트 모듈은 직류 전압 형성부 및 직류 전압 형성부를 제어하는 제어부를 포함하며, 직류 전압을 제공하는 테스트 모듈 및 복수의 테스트 모듈들이 제공하는 직류 전압들의 평균 전압값을 연산하여 제공하는 연산부를 포함하며, 제어부는 연산부가 제공한 평균 전압값과 직류 전압의 차이에 상응하는 전압 오프셋을 연산하여 직류 전압의 전압값이 평균 전압값에 상응하도록 제어한다.
