Car Battery Bus Bar
Products Description
The Car Battery Bus Bar is a solid, well-designed conductor built for modern automotive battery packs. Instead of relying on many separate wires, it uses a single metal bar (usually copper or aluminum) to channel high currents efficiently and reliably. Because of its low electrical resistance and wide cross-section, the busbar insulator moves power with minimal loss - which means less heat, more stable voltage, and better overall energy transfer in demanding applications like EV battery systems.
At the same time, its rigid, compact form helps battery packs stay neat and strong. Using a auto bus bar simplifies the internal wiring layout, reduces weight compared with bulky harnesses, and improves mechanical robustness - which matters a lot when a vehicle is subject to vibration or vibration-induced stress. For electric vehicles, hybrid cars or any high-current automotive energy storage, this busbar supports gives a clean, efficient, and dependable foundation - helping make battery systems safer, more compact, and easier to assemble.
Raw Material & Base Material Standards
The tinned copper busbar is constructed from high-purity red copper (a key industry term: high-conductivity red copper), complying with global mainstream material standards:
EV Battery Connector adheres to domestic standard GB/T2Y2, and international standards including DIN E-Cu58 (2.0065), EN Cu-ETP (CW004A), ISO Cu-ETP, UNS C11000, JIS C1100, and BS C101;
Busbar isolation's opper purity reaches ≥99.99%, ensuring a conductivity of 97% IACS, while maintaining a hardness of 80~110HV and tensile strength of 245-345MPa-balancing electrical performance and mechanical stability;
Battery terminal bus bar Customizable base materials (e.g., aluminum, copper alloys) are available to meet differentiated application requirements.
Insulation Protection Options
Multiple insulation solutions are offered to suit different working conditions for the busbar insulation paint:
| PET insulation paper | Insulated copper bus bar uses imported materials from brands like GTS (USA) and KREMPEL (Germany), primarily in white/ivory, with excellent insulation strength and temperature resistance |
| PVC impregnation | Busbar insulator popular in orange and green, featuring mature processes and cost-effectiveness |
| Epoxy powder coating | Auto bus bar available in orange, green, and gray, with outstanding insulation performance |
| PE heat shrink tubing | Busbar supports' optional colors include orange, green, black, red, and yellow, enabling easy installation; |
| PA66 plastic housing | Tinned copper busbar mainly in white and gray, suitable for complex assembly scenarios |
