Flexible Busbars & Shunts Insulated for EV Applications

The flexible aluminum busbar, made from foil or strip and insulated, offers excellent conductivity, heat dissipation, and flexibility. It's lighter and more cost-effective than copper, while meeting current capacity needs. Ideal for high-voltage connections in EV battery packs, it supports integrated assembly for electric vehicles.

Flexible bus bars are made up of layers of copper foils in various width and number of layers. Copper foil thickness can be from 0.1mm to 1mm. Because of it’s feature of good conductivity, flexible, easy to install and space saving, flexible busbars are widely used in electric vehicle battery pack, new energy power distribution system, UPS, Charging pile etc.

Bus Bar Performance:
