Aluminum Busbar: CCS Busbars for EV Battery Connections

Compared to traditional wire harnesses, CCS busbars offer higher reliability, better sealing, and efficient heat dissipation. They simplify installation, support high automation, and reduce labor costs. Flexible connections allow for multiple configurations, with built-in overcurrent protection ensuring battery safety.

RHI manufactures and supplies a wide range of aluminum busbars.

Strength: Quality aluminum has sufficient tensile strength to withstand thermal expansion strain, varying from dead soft to mild steel depending on the alloy used.

Ampacity: Contingent on busbar size, aluminum busbar can handle currents up to 4000A, which is more than sufficient for many applications.

Conductivity: Aluminum busbar conductivity is dependent on the alloy and temper. Pure aluminum conductivity is approximately 65.0% of IACS.

Resistance: High quality, high strength aluminum can have mechanical resistance up to 530 Newton/mm2. Aluminum is fatigue resistant and corrosion resistant. Aluminum also offers easy corrosion removal with simple stripping.

Weight: Aluminum can be as much as 70% lighter than copper.

Aluminum Bus Bar Advantages:

  • High Corrosion Resistance

  • Good Conductivity

  • Great Heat Exchange

  • Efficient Thermal Dissipation

  • Lightweight

  • Cost Effective

Applications

Aluminium busbars are extensively used in electric vehicles and excel in outdoor or corrosive, high-stress environments. They are commonly employed for electrical suppression in low-voltage applications, offering moderate strength and lightweight properties. These battery busbars are particularly suitable for compact enclosures.
