Flexible Bus Bar Connectors for New Energy Vehicles

Flexible busbars, made from thin layers of copper foil or strips and covered with a heat shrink insulation layer, offer excellent conductivity and heat dissipation. Compared to rigid copper busbars, they are lighter and allow for more flexible and adaptable installation. Flexible copper busbars are widely used in EV battery packs, distribution cabinets, energy batteries, solar panels, etc.

Product Description

Flexible bus bars are composed of multiple layers of copper foils, varying in width and number of layers. The thickness of these copper foils ranges from 0.1mm to 1mm. Thanks to their excellent conductivity, flexibility, ease of installation, and space-saving design, flexible busbars are widely used in EV battery packs, new energy power distribution systems, UPS systems, charging piles, and more.
