[0002] DC internal resistance (DCIR) refers to the ratio of the voltage change of the battery under working conditions to the corresponding discharge current change. In the automatic production process of the battery, it is necessary to test the DC internal resistance of the produced battery to detect the performance of the battery; in the past The DC internal resistance test of the battery generally relies on manually connecting the positive and negative wires to the corresponding electrodes of the battery and then energizing to measure the DC internal resistance of the battery. When the working current of the battery is large, manual wiring is prone to poor contact and cause measurement errors. Even a short circuit occurs, causing battery damage
[0003] For this reason, a kind of DCIR testing machine is proposed in the prior art, and a plurality of batteries are placed in the transport tray, and the control tray moves toward a plurality of current probes, so that the current probes touch the batteries, and then supply power to the batteries; when it is necessary to test For batteries of different sizes, not only the battery tray needs to be replaced, but also the current probe sets of different sizes need to be replaced, which takes a long time to replace
