CHARGE/DISCHARGE TEST SYSTEM, CALIBRATOR UNIT, AND CHARGE/DISCHARGE TEST DEVICE

摘要

PROBLEM TO BE SOLVED: To solve the problem that it is conventionally impossible to efficiently perform calibration work of a charge/discharge test device for testing a secondary battery.SOLUTION: A calibrator unit for calibrating a charge/discharge test device for use in testing a secondary battery is constituted of connection terminals in the same arrangement as the secondary battery and an enclosure having the same shape as the secondary battery and includes: a measurement part which is connected to the connection terminals instead of the secondary battery to measure electric characteristics; a power supply part which supplies the unit with power inputted from the charge/discharge test device via a preliminarily determined part of the connection terminals; and a switching part which switches connections so that the connection terminal for receiving the power from the charge/discharge test device is connected to the power supply part and the connection terminals for measuring electric characteristics between the unit and the charge/discharge test device are connected to the measurement part.
