Product Details

Advanced Engineering for Structural Battery & High-Voltage Safety

  • 1200V Partial Discharge-Free Technology: Our busbars undergo rigorous testing to ensure they remain Partial Discharge-Free at 1200V+, preventing insulation breakdown in high-frequency SiC switching environments.

  • Cell-to-Body (CTB) Integration: Optimized for structural battery packs, our 3D Formed Busbars reduce space requirements while acting as a structural reinforcement for the battery module assembly.

  • Mica-Insulated Thermal Barriers: For LFP and high-nickel battery chemistry, we offer Mica-wrapped busbars that provide critical protection against thermal runaway propagation.

  • Ultrasonic Bimetallic Welding: We utilize advanced Ultrasonic Welding to join copper terminals with Nickel-Plated Aluminum rails, achieving a 30% weight reduction while maintaining superior electrical conductivity.

  • Press-Fit & Automated SMT Compatibility: To support high-speed OEM Electronics Manufacturing, our busbars feature Press-Fit terminals, eliminating the need for manual soldering and increasing assembly throughput.

  • Shielded EMI Suppression: Our Shielded High-Voltage Harnesses incorporate integrated Faraday cages to mitigate electromagnetic interference, protecting sensitive BMS sensors and communication lines.

Product Applications:

  • 800V/1200V SiC Traction Inverters: Low-inductance power rails designed specifically for the fast-switching frequencies of Silicon Carbide power electronics.

  • Cell-to-Chassis (CTC) Battery Packs: Specialized interconnects for integrated vehicle architectures where the battery pack forms part of the car's floor structure.

  • Ultra-Fast Charging Infrastructure: High-creepage distance busbars designed for 350kW+ DC Fast Chargers and Megawatt Charging Systems (MCS).

  • Electric Heavy-Duty Trucks: IP69K Rated and vibration-resistant busbar harnesses engineered for long-haul commercial electric transport and construction machinery.

  • eVTOL & Electric Aerospace: AS9100-compliant lightweight bimetallic busbars for the emerging electric vertical takeoff and landing aircraft market.

  • Marine EV Systems: Corrosion-resistant Tinned Copper Busbars with high-dielectric strength for electric ferries and luxury electric yachts.
