Battery Aluminum Busbar for New Energy

Aluminum busbars can be customized in various models and sizes. They are ideal for power connections and transmission in EV battery packs. The main differences between aluminum and copper busbars are that aluminum is more cost-effective and lighter.

RHI provides a comprehensive range of aluminum busbars with excellent mechanical and electrical properties:

  • Strength: High-quality aluminum offers strong tensile resistance to thermal expansion. Depending on the alloy, its strength ranges from soft annealed to near mild steel.

  • Ampacity: Capable of carrying up to 4000A, depending on cross-sectional area, ensuring reliable performance in high-power applications.

  • Conductivity: Varies by alloy and temper; pure aluminum achieves ~65% IACS, balancing efficiency and cost.

  • Durability: High-strength aluminum withstands up to 530 N/mm², offering excellent fatigue and corrosion resistance. Oxide layers can be easily removed.

  • Weight Advantage: Up to 70% lighter than copper, reducing structural load and improving handling efficiency.
