Description

Technical Field

[0001] The utility model belongs to the technical field of new energy battery testing, and in particular relates to a detection device for quickly installing soft-pack battery cells. Background Art

[0002] The thickness of the tabs of soft-pack batteries is relatively thin. The positive electrode is made of aluminum (Al) with a thickness of 0.2-0.6mm, and the negative electrode is made of copper-plated nickel (Ni-Cu) with a thickness of 0.2-0.6mm.

[0003] The positive and negative connectors of the charging and discharging equipment used to test the electrical performance of soft-pack batteries are generally copper open noses. If they are to be connected, holes need to be punched at both ends of the positive and negative electrodes of the battery cell and connected with bolts. This method will have several disadvantages:

[0004] 1. The contact resistance does not meet the requirements; 2. The battery cannot be kept intact; 3. Fixing with bolts will damage the tabs.

[0005] Therefore, it is important to provide a detection device that can conveniently connect the positive and negative electrodes of a soft-pack battery to a charging and discharging device. Utility Model Content
