Trusted by leading battery and automotive OEMs worldwide — delivering precision busbars for the future of mobility.
1. Fast-Charging Aluminum Busbar Application Case
Customer: Leading Battery OEM
Application: Cost-optimized high-voltage connection solution for LFP power battery packs in passenger EVs.
Requirements:
Withstand voltage above 1000V
Lighter and more cost-effective than copper/aluminum cables
Compatible with integrated vehicle layout
Solution: Manufactured from 1xxx series aluminum via stamping, punching, plating, Insulation, and precision bending. Aluminum-to-copper transition
joints are applied at terminals to mitigate galvanic corrosion and stress relaxation.
Key Benefits:
Lightweight & Cost Reduction: Aluminum weighs ~1/3 of copper at equal volume and costs ~1/4 at equal weight
Higher Current Capacity: Larger surface area than stranded aluminum cables at the same cross-section, enabling higher current carrying capability
and lower resistance
Flexible Integration: Low profile and tight bending radius reduce mounting points and optimize routing space
Fast-Charging Ready: Meets current and thermal rise requirements under 4C–5C fast-charging conditions, supporting efficient connections for 100
GWh-scale battery production
