| description | The embodiment of the invention provides a circulating current testing method and system, and belongs to the technical field of batteries. The method comprises the steps that a plurality of test groups are acquired, the ratio of the direct-current internal resistance of at least two modules arranged in parallel in each test group is the same as the ratio of the direct-current internal resistance of a battery pack, and the battery pack comprises at least two batteries arranged in parallel; and charging or discharging the at least two modules arranged in parallel in each test group. According to the technical scheme, the test group occupying a small space is used for replacing the battery pack to serve as the sample for the circulation test, so that the problem that the operability difficulty is high when the battery pack is directly used as the sample for the circulation test is solved, and the operability difficulty of the circulation test is reduced.
