New energy power batteries consist of multiple cells forming a module, and multiple modules are combined to form a power battery. The series connection of multiple modules necessitates conductive connections. Currently, new energy vehicles primarily utilize flexible copper busbars for series connection. These busbars offer excellent conductivity, outer insulation protection, and a flexible structure in the middle that buffers stress during driving, ensuring vehicle safety and stability. As a key conductive component in battery systems, copper busbars have a significant impact on the stability and safety of the entire battery system. Copper busbar flexible connections are used in a wide range of applications, including but not limited to transformer installation, high- and low-voltage switchgear, vacuum electrical equipment, enclosed busbars, connections between generators and busbars, rectifiers, rectifiers and disconnectors, and between busbars. These copper busbars play a vital role in new energy vehicles, energy storage systems, and power distribution systems, ensuring smooth current transmission and safe system operation.
