Flexible copper, aluminum CCS, and insulated links for EV electrical connections.
An EV electrical connection has to carry current between the cell, the module, the pack terminals, and the rest of the high-voltage path. RHI supplies flexible copper busbars, aluminum busbars for cell contact systems, and insulated connectors for that path.
The parts are bent, punched, welded, and insulated in Yueqing. Insulation on the current catalog includes heat-shrink sleeve and PA12 extrusion.
Flexible insulated busbars feature laminated electrolytic copper conductors, tin or nickel plated surfaces, and EVA heat shrink insulation. With 97 percent IACS or higher conductivity and a temperature resistance range from -50 to 125 degrees Celsius, these copper busbars provide reliable high current transmission from 125A to 1600A for EV batteries, ESS, and power distribution systems.
Flexible busbars, made from thin copper or aluminum foil layers, offer excellent conductivity and flexibility. Their insulation improves heat dissipation, reduces vibration, and saves space. Widely used in EV battery packs, energy systems, UPS, and charging stations, they provide reliable performance in compact environments.
Copper busbars for AI battery backup units and energy storage racks.
RHI Rack Busbars are designed for OCP ORv3 Open Rack systems and high-density AI data centers, providing standardized high-current DC power distribution through a laminated busbar structure. With current ratings ranging from 425A to 2900A, they support diverse power requirements for Power Shelves, PSU modules, BBU systems, AI servers, storage, and network switches. Blind-mate connections simplify installation, reduce cabling complexity and voltage drop, while the vertical busbar design helps reduce cable congestion, improve airflow, and simplify rack maintenance. Custom designs are available to meet specific rack configurations and power requirements.
Flexible busbars are made from copper foil with thicknesses ranging from 0.1 to 1mm. Produced through welding, stamping, plating (tin or nickel), forming, and insulation (PVC dipping or PE heat shrink tubing), they offer excellent conductivity, flexibility, easy installation, and space-saving design. These features make them ideal for EV battery packs, new energy power distribution, UPS systems, and charging stations.
Rigid copper busbars excel in both mechanical strength and electrical conductivity, making battery bus bars ideal for applications demanding superior performance in both areas. And the PVC insulation offers excellent wear and weather resistance, making these insulated busbars perfect for demanding environments that need robust, stable power transmission and distribution.
