Challenge

EV battery packs and energy-storage equipment may need conductors that fit compact layouts and accommodate specified movement or assembly tolerances. Conductor geometry, insulation coverage and connection interfaces must be matched to the equipment design.

Flexible Copper Busbar Challenge - Compact Battery Layout

Solution

Flexible laminated busbars use layers of copper foil with insulation and formed or joined terminals. Foil thickness, stack design, bend radius, insulation and validation tests are specified for the customer application.

  • Copper-foil layers and conductor cross-section per drawing
  • PE or PVC insulation where suitable for the design
  • Bend radius and mechanical tests defined by the application
  • Custom shapes for EV, energy storage, charging piles & more

Why Choose Us

Key Advantages

High Conductivity

Copper-foil conductors provide a low-resistance current path when material grade and cross-section are correctly specified.

Lightweight & Flexible

The layered construction can accommodate custom shapes and simplify installation in confined spaces.

Application-Specific Flexibility

Bending requirements depend on foil construction, radius and movement. Durability testing should match the actual duty cycle.

Specified Protection

Insulation and surface finish are selected to suit the operating temperature and environment specified for the project.

FAQ

Frequently Asked Questions

What is a flexible laminated copper busbar?

A flexible laminated busbar is made from layers of copper foil joined at the terminals and insulated as required. Its geometry can be tailored for EV batteries, energy storage and power-distribution assemblies.

What applications are flexible busbars used for?

Flexible laminated busbars are used in electric vehicle powertrain systems, energy storage batteries, EV charging piles, high-voltage cabinets, switchgear assemblies, air-cooled battery pack systems, and transformers. Their flexibility makes them ideal for dynamic environments with vibration and thermal cycling.

What conductivity do your flexible busbars achieve?

Conductivity depends on the selected copper grade, cross-section and finished assembly. Material documentation and temperature-rise testing can be specified for the project.

What is the bending durability of flexible busbars?

Bending durability depends on foil stack, bend radius and movement amplitude. A project-specific test should be defined if repeated flexing is expected.

What insulation materials are available?

PE and PVC are possible insulation options. The selected grade, thickness, dielectric rating, temperature range and flame classification must be confirmed for the finished design.

What conductor materials can be used?

Copper foil grade and any alternative conductor material are selected against the drawing, electrical requirements and supply specification.

What surface finishes and documents can be specified?

Tin, nickel and other terminal finishes can be discussed for the application. Confirm any corrosion tests, material documents or certifications required for the specific order during quotation.
