Abstract: An inspection circuit includes a plurality of inspection devices and a plurality of pathway switching circuits. Input ends of the pathway switching circuits are respectively connected to different test lines. The test lines are connected to a test terminal corresponding to a battery cell under test. Output ends of the pathway switching circuits are respectively connected to the plurality of inspection devices. The pathway switching circuit is configured to connect, according to an inspection signal, an inspection device corresponding to the inspection signal and a test terminal corresponding to the battery cell under test. The inspection device is configured to obtain an inspection result of the battery cell under test.

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: A battery test apparatus includes a lifting mechanism and a probe mechanism. The lifting mechanism is configured to drive the probe mechanism to move. The probe mechanism includes an adapting rack and a plurality of first connecting members disposed on the adapting rack. The adapting rack is detachably connected to the lifting mechanism.

Abstract: The present application relates to a detection mechanism and a battery production line. The detection mechanism includes a conveying unit, configured to convey the device to be detected; a first detection unit, configured to detect the temperature of the device to be detected; and a trigger unit, configured to detect the distance between the first detection unit and the device to be detected. When the distance between the first detection unit and the device to be detected is less than a preset distance value, the trigger unit controls the conveying unit to stop conveying. The detection mechanism and the battery production line in the embodiments of the present application can ameliorate the problem of poor universality.
