TEST ARRANGEMENT OF AN ENERGY STORAGE DEVICE

摘要

For an efficient, economical and at the same time flexibly usable or configurable test arrangement for energy storage devices consisting of a plurality of energy storage modules each comprising a plurality of energy storage units, it is proposed that an AC/DC converter (2) is connected on the output side to at least one bidirectional isolated module DC/DC converter (51 . . . 5n), wherein the output of the bidirectional isolated module DC/DC converter (51 . . . 5n) is connected to a plurality of parallel-connected cell DC/DC converters (611 . . . 6nm) and the outputs of the cell DC/DC converters (611 . . . 6nm) are brought out as outputs (A1+, A1− . . . Ax+, Ax−) of the test arrangement (1).
