Abstract

The invention discloses a square battery multifunctional test fixture with an adjustable test size and an operation method. The fixture comprises a test seat, an upper clamping mechanism, a lower clamping mechanism, a lifting mechanism and a locking mechanism, wherein the test seat comprises a bottom plate and a back plate which are connected with each other, the lower clamping mechanism is movably connected with the bottom plate, the bottom surface of a to-be-tested battery is attached to the bottom plate, the side surface of the to-be-tested battery is attached to the back plate, the lower clamping mechanism is used for clamping the bottom of the to-be-tested battery, and the lifting mechanism is movably connected with the test seat and is used for driving the upper clamping mechanism to do lifting motion. The locking mechanism is used for locking the position of the lifting mechanism, the upper clamping mechanism comprises a main board, at least one positive clamping plate, at least one negative clamping plate and a conductive plate, the positive clamping plate and the negative clamping plate are movably connected with the main board and are connected with the conductive plate, and the conductive plate is used for making contact with electrodes of a battery to be tested. And the conductive plate is electrically connected with the test equipment through the wiring terminal.

Description

technical field [0001] The invention relates to the technical field of battery test fixtures, in particular to a square battery multifunctional test fixture with adjustable test size and an operation method. Background technique [0002] With the rapid increase in the number of electric vehicles, the demand for the use of power batteries for electric vehicles is also increasing. Therefore, the safety requirements for power batteries are also constantly improving. The industry stipulates that the current overcharge and discharge test of the power battery should not explode, fire or leak. The corresponding safety indicators are set for the battery current test to ensure the safety of the power battery for electric vehicles. However, in various current tests for square batteries, it is necessary to connect the positive and negative poles of the battery to the test equipment. Since the structure of the joint end of the test equipment and the positive and negative tabs of the ba...
