Abstract: A test system comprises a test circuit board, a test device, a lower computer, and an upper computer. The test circuit board includes a test circuit, the test circuit comprising multiple main lines arranged side by side, one end of each of the main lines being used to connect with a positive electrode or a negative electrode of each battery cell of the battery module, and the other end of each of the main lines being connected with a first branch and a second branch. The lower computer controls a first branch connected to one of the main lines to be electrically conductive to a positive electrode of the test device and a second branch connected to another one of the main lines to be electrically conductive to a negative electrode of the test device. The upper computer controls the lower computer and reads parameter information for the test device.

Abstract: The present disclosure discloses a testing system, a battery production line, and a testing method. The testing system includes a control device and a test device. The test device includes at least two probe card adjustment assemblies. The control device is connected to the test device and configured to adjust the probe card adjustment assemblies according to an adjustment strategy, and drive the adjusted probe card adjustment assemblies to test the battery module currently to be tested. The adjustment strategy is determined based on current module information corresponding to the battery module and historical module information. The historical module information is the module information of a battery module tested last time. The technical solution provided by the embodiments of the present disclosure can quickly adjust the probe card adjustment assemblies to adapt to different battery modules.
