About this material
Inside a pack, busbars carry the full pack current between cells and modules. The design constraint is a balance between cross-section, which sets resistive loss and temperature rise, and mass, which the pack can ill afford. Aluminium is the usual choice for the main current path because its conductivity-to-weight ratio is favourable and it welds cleanly by laser to aluminium cell terminals.
Joints are where packs fail. Aluminium develops a tenacious oxide layer within minutes of exposure to air, which is why surface condition and cleaning immediately before welding matter more than the alloy specification. Where a busbar must bolt to a dissimilar metal, a nickel-plated finish is normally specified to control galvanic corrosion at the interface.
Documentation, controls and care
Quality controls
- Dimensional inspection against drawing
- Conductivity tested on sample basis
- Burr height checked at cut edges
- Plating thickness verified where specified
Handling & storage
- Keep in moisture-barrier packaging until welding — surface oxide raises joint resistance.
- Do not handle welded surfaces with bare hands.
- Store flat; bends introduced in transit will not meet the drawing.
