Structure Design and Processing Technology Of Copper Battery Bus bar

1. Diversified structure

  • Single busbar structure: simplify the installation process, suitable for standard battery modules.
  • Multi-bus parallel structure: Redundant design by increasing the current-carrying cross-section (max. 100mm wide x 10mm thick), increasing current-carrying capacity by 40%.

2. Surface treatment technology

  • Basic protection: 3-5μm tin plating (in accordance with EN 13601 CW004A)
  •  Special treatment: optional silver plating (contact resistance reduced by 15%) or nickel plating (salt spray resistance ≥ 500h)
  • Insulation solution: double composite protection (PE heat-shrinkable tube + PVC dip molding), temperature resistance -40 ℃ ~ 125 ℃
