MULTIMODE CHARGE/DISCHARGE TEST DEVICE AND MULTIMODE CHARGE/DISCHARGE TEST METHOD

摘要

PROBLEM TO BE SOLVED: To provide a multimode charge/discharge test device which can perform a multichannel charge/discharge test and which can also perform a charge/discharge test through a high-voltage single channel when needed.SOLUTION: A multimode multichannel charge/discharge test device which performs charge/discharge tests of a plurality of storage batteries at the same time includes: a plurality of charge/discharge units corresponding to each storage battery, which perform each charge/discharge test of the storage batteries in a multichannel charge/discharge mode, and switch sections which connect the plurality of charge/discharge units in series in a high-voltage charge/discharge mode.
