Copper-to-Aluminium Busbars for EV Applications
RHI uses advanced diffusion welding to produce copper-aluminium busbars, with aluminium as the primary conductor and rigid copper welded at the ends. This lightweight and cost-effective composite busbar is ideal for cost-sensitive power connections, combining copper's conductivity with aluminium's low weight, ensuring excellent performance while reducing equipment weight.
Copper-aluminium busbars joined by welding offer a cost-optimized solution, widely used in new energy high-voltage interconnection systems. Atomic welding enables T2 copper to be metallurgically bonded with 1060 aluminium, creating a permanent and reliable joint. This process preserves the properties of both materials and supports continuous automated production.
These copper-aluminium busbars are increasingly replacing copper busbars in EV battery packs, energy storage systems, high-voltage cabinets, panel board, and air-cooled Pack systems, etc. These custom busbars effectively prevent issues like surface oxidation, arcing, and overheating, resulting in lower power consumption and providing substantial economic and practical advantages.
