Tin coated copper busbar connector for EV battery packs, energy storage systems and power distribution. Custom shapes, hole patterns and surface finishes support OEM/ODM industrial purchasing.
Our Tin-coated copper busbars is a key conductive component in new energy vehicle battery packs, which is mainly used to efficiently transmit high currents, connect battery monomers, reduce contact resistance, and adapt to complex working conditions. Its surface tinning treatment significantly improves oxidation and corrosion resistance, and is widely used in electric vehicle powertrain, charging pile and energy storage system.
