Copper Aluminum Terminal for Power Battery

Wholesale quality Copper Aluminum Terminal for Power Battery from Zenko factory in China. It is purpose-built for internal battery pack connections where copper busbars meet aluminum current collectors. Manufactured by the Chinese supplier Zenko with explosion welding technology, it creates a permanent, low-resistance bond that withstands the thermal cycling and vibration inherent in battery operation.

Power battery packs operate under demanding conditions—repeated charge/discharge cycles generate heat, vibration from vehicle motion stresses connections, and any increase in contact resistance accelerates degradation. The Copper Aluminum Terminal for Power Battery ensures stable, low-resistance connections throughout the battery system service life.

Battery-Specific Challenges

●Thermal cycling:  Charge/discharge cycles cause repeated heating and cooling of connections

●Internal heating:  Battery cells generate heat that transfers to terminals and busbars

●Vibration stress:  EV operation subjects battery pack connections to continuous vibration

●Safety critical:  Connection failure inside a sealed battery pack is catastrophic

●Space constrained:  Battery modules have minimal clearance for oversized connections

●Long service life:  Battery packs designed for 8-15 years, terminals must match

Key Features

●Ultra-low resistance:  Explosion-welded bond minimizes contact resistance for battery efficiency

●Thermal stability:  Maintains connection integrity through thousands of thermal cycles

●Short-barrel design:  Compact form factor fits tight battery module spacing

●Tin-plated surface:  Prevents oxidation in sealed battery enclosure environments

●Heat-resistant:  Rated -40°C to +125°C for battery thermal conditions

●Vibration tested:  Validated for battery pack vibration profiles per ISO 12405
