Rivet Nuts for Aluminum EV Battery Trays

Rivet Nuts for Aluminum EV Battery Trays

Design Considerations for Thin-Wall Aluminum Battery Structures

Aluminum is widely used in EV battery trays because it offers low weight, good corrosion resistance, and favorable structural properties.

However, fastening thin aluminum panels can be challenging.

A rivet nut for aluminum creates a dedicated threaded fastening point without requiring a welded nut or thick threaded boss.

Why Use Rivet Nuts in Aluminum?

Directly tapping thin sheet can result in limited thread engagement.

A rivet nut provides a mechanically retained insert.

This can improve:

• Thread engagement

• Assembly efficiency

• Serviceability

• Design flexibility

Important Design Considerations

Panel Thickness

The panel thickness must match the rivet nut grip range.

Hole Diameter

The hole must be controlled within the manufacturer's specified tolerance.

Thread Size

The thread should be selected based on:

• Fastener size

• Clamp load

• Installation torque

• Available space

Pull-Out Resistance

The surrounding aluminum must provide sufficient resistance to axial loads.

Spin-Out Resistance

The installed insert must remain stable during tightening and removal.

Corrosion Compatibility

When steel or stainless steel fasteners are installed in aluminum, engineers should consider galvanic corrosion.

Material selection, coatings, isolation, and environmental exposure all matter.

EV Battery Tray Applications

Rivet nuts can be used for:

• Battery tray covers

• Brackets

• Cable management

• Thermal management components

• Electrical components

• Service panels

• Battery module assemblies

Sealed Aluminum Battery Trays

Where environmental protection is required, closed-end sealed rivet nuts can be considered.

The final sealing performance should be evaluated with the enclosure gasket and complete assembly.
