Copper Bus Bar for Battery Pack

Flexible busbars use copper or aluminum strips with EVA/PE heat shrink or PVC dip-coated insulation. They resist corrosion and high temperatures, reduce stress, simplify wiring, and allow flexible installation. Common in EV battery packs, they withstand vibrations, prevent creep, and offer a safer, low-maintenance alternative to cables.

Flexible busbars use copper or aluminum strips as conductors, with insulation options of EVA/PE heat-shrink or PVC dip coating. They offer corrosion and heat resistance, reduce stress concentration, allow flexible installation, simplify wiring, and maintain stability without creep under long-term current. Compared to traditional cables, they ensure lower maintenance costs.

Bus Bar Performance:

Conductivity: 57%；

Tension strength: ≥500N；

Insulation flame retardant: UL94V-0；

Insulation temperature resistance: -45℃ to 150℃；

Resistance to corrosion: It can pass 240H salt spray test in neutral environment；

Temperature rise: Depends on cross section area. RHI can provide temperature rise reports for all products；

Bending Testing: Bend 10000 times in 15 radian angle without breakage or fracture.
