Method for efficiently detecting short-circuit battery cell of lithium ion battery

The invention discloses a method for efficiently detecting a short-circuit cell of a lithium ion battery, which comprises the following steps of: placing a lithium battery workpiece to be detected on two groups of workpiece conveying belts of a short-circuit cell detection device, conveying the workpiece by the workpiece conveying belts, stopping working of a direct-drive motor when a photoelectric sensor detects workpiece information, and stopping working of the direct-drive motor when the photoelectric sensor detects the workpiece information; and the probe reciprocating pushing mechanism is used for pushing the electrode detection probe to move downwards until the electrode detection probe is in contact with the positive electrode and the negative electrode of the lithium battery workpiece, and current and voltage values detected by the electrode detection probe are sent into a control panel for judgment. Through a double-step detection mode, the detection error of the device is reduced, the process does n
