CHARGE/DISCHARGE TEST APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a charge/discharge test apparatus capable of preventing overshoot at start of test without giving additional load to a sample 3 in a charge/discharge test in a constant voltage mode.SOLUTION: A charge/discharge test apparatus 10 has a control unit 15 which carries out a charge/discharge test on a sample 3 using a preset initial current value and a constant voltage value in a constant voltage mode. After starting the test, the control unit 15 measures an impedance value on the sample 3 before the current flowing on the sample 3 reaches the initial current value. The control unit 15 checks whether or not the initial current value which is set based on the measured impedance value is in a proper range. When the value is out of the proper range, the control unit 15 changes an initial current value.SELECTED DRAWING: Figure 1
