Description

Technical Field

[0002] Because lithium-ion batteries have the advantages of high specific energy, many cycles and long storage time, they are widely used in mobile phones, digital cameras, laptops, electric vehicles, electric bicycles and other devices.

[0003] The Chinese utility model patent with publication number CN216117938U proposes a lithium battery cell short-circuit test device, which includes a support back plate, a sliding panel and a test probe. A slide rail is installed on the bottom surface of the support back plate, and the sliding panel is installed on the slide rail. A second cylinder is provided on the back of the support back plate. The second cylinder is connected to the sliding panel through a telescopic plate and controls the sliding panel to slide along the slide rail.

[0004] The above technical solution drives the telescopic plate and the sliding panel through the second cylinder. The sliding panel drives the lithium-ion battery to move to the bottom of the pressure plate through the fixed groove, and drives the pressure plate to descend through the first cylinder, so as to perform short-circuit detection on the lithium-ion battery, ensuring that when the device measures each lithium battery, the force degree of the measuring contact and the contact surface is the same, thereby ensuring the consistency and accuracy of the measurement results. However, only one fixed groove is provided, and only one lithium-ion battery can be short-circuit tested at a time, and lithium-ion batteries cannot be tested in batches, which reduces the production and processing efficiency of lithium-ion batteries.

[0005] To this end, the utility model provides a battery cell testing device. Utility Model Content

[0014] Furthermore, a vertical plate is fixedly installed on the top of the rear end of the workbench, the shape of the vertical plate is "U"-shaped, and a multimeter is fixedly installed on both sides of the vertical plate.
