[0002] When the battery of a new energy vehicle is retired, it still has a certain remaining capacity. Before cascade utilization, it is necessary to detect the voltage of retired batteries with different performances, and effectively sort out the retired batteries that do not meet the requirements for subsequent treatment and resource recovery. The existing technology usually uses a power source to drive a conduction rod to insert into the positive and negative electrode interfaces of the battery, and a conduction rod with a voltmeter is used for direct detection. When the battery pack voltage of the retired battery to be detected is outlier, the voltmeter will transmit information to the controller and alarm.

A conveying device is arranged in the middle of the support frame, and a plurality of battery slots are arranged on the conveying device, and a battery pack is arranged in the battery slots; By setting a controller to control the third hydraulic cylinder to drive the voltmeter to move up and down to detect the voltage of the battery pack. When the battery pack voltage is outlier, the voltmeter transmits information to the controller, and the controller controls the alarm lamp to light up to screen out the battery packs with large differences, which can achieve the effect of quick screening. However, in actual use, the battery pack is extremely likely to shift on the conveying device, making the conduction rod unable to align with the positive and negative electrode interfaces of the battery pack, resulting in frequent missed detections during the sorting stage.
