CHARGE/DISCHARGE TEST SYSTEM AND METHOD OF CONTROLLING CHARGE/DISCHARGE TEST SYSTEM

A charge/discharge test system (10) includes: a two-way AC/DC converter (12); a charge/discharge test device (20) that includes a DC bus (14-2), a two-way DC/DC converter (30) having one end connected to the DC bus, and a converter control unit (40); a setting unit (18) that sets a charge/discharge pattern (P1, P2) corresponding to a test charging/discharging object (28-1) serving as a target of a charge/discharge test among charging/discharging objects (28, 28-1, 28-2); and a prediction unit (44) that generates a power prediction pattern (SP) indicating a temporal change in a total value of charge and discharge power of a testing converter (30a) corresponding to the test charging/discharging object in the two-way DC/DC converter, based on the charge/discharge pattern, and the converter control unit controls charging and discharging of the charging/discharging object performed by the two-way DC/DC converter, based on the charge/discharge pattern and on the power prediction pattern.
