Copper Battery BusBar
Products Description
A Copper Battery BusBar is essentially a copper conductor structure used for current convergence and energy distribution. It replaces traditional wiring harnesses with a planar conductive structure, achieving a more stable and efficient high-current connection solution.
Depending on different system requirements, the product can be applied to:
Battery module connections
PACK high-voltage circuits
PCS energy storage systems
Photovoltaic inverters
UPS power systems
Server power systems
High and low voltage power distribution equipment
High-voltage power distribution units (PDUs) for new energy vehicles
The product can be a simple planar copper busbar, or a complex, irregularly shaped, bent busbar, a multi-hole connection busbar, or an integrated insulation structure busbar.
Application Advantages: Comprehensive Adaptability to Industrial Power Needs Across Multiple Scenarios
New Energy Photovoltaic and Wind Power Generation
High-power DC/AC interconnect Copper Ground Bus Bars used in combiner boxes and inverters, resistant to extreme outdoor temperature variations.
UPS Uninterruptible Power Supply and Super Data Center Servers
Handling uninterrupted transmission of ultra-high current in high-density computing blade server racks (Power Distribution Units, PDUs) and modular UPS systems.
New Energy Vehicle Battery Packs
Serving as power connectors between series and parallel battery cells, meeting automotive-grade requirements for lightweight design, shock resistance, and vibration resistance.
Traditional Power and Rail Transportation
Suitable for high and low voltage switchgear, distribution panels, industrial electrolytic cells, and subway/high-speed rail traction power supply systems.
Material Advantages: Lattice-Level Conductivity of High-Purity Copper Substrate
Lattice Channels with Extremely Low Electron Scattering
The extremely low impurity content of high-purity copper eliminates electron scattering effects at grain boundaries, bringing the mobility of free electrons close to the theoretical limit, thus eliminating useless power consumption caused by bulk resistance at the source.
Excellent Thermal Conductivity and Heat Capacity Ratio
Copper has extremely high thermal conductivity, allowing the Distribution BusBar to instantly conduct Joule heat to both ends or the heat dissipation surface when subjected to localized large current accumulation, avoiding insulation aging or thermal runaway caused by localized temperature rise.
High Ductility and Cold Work Hardening Resistance
After bending and stamping, the high-quality copper substrate exhibits a gradual increase in hardness in the cold work hardening zone, making it less prone to microcracks and ensuring the long-term maintenance of the flatness of the connection surface and the fastening torque after forming.
