Aluminum Busbar for Battery Connection

Aluminum busbars are primarily used to transmit current between battery cells, modules, packs, BDUs/PDUs, and other high-voltage electrical components. Compared to traditional cable connections, they provide a more compact, repeatable, and rigid conductive path.

Aluminum busbars use aluminum as the primary conductor, offering advantages in weight reduction and structural adaptability. Copper-aluminum busbars combine copper and aluminum, allowing specific zones to handle conduction, connection, or weight reduction functions respectively; this makes them better suited for battery systems with specific terminal connection requirements.

Yes. Products can be customized based on 2D engineering drawings, 3D models, samples, or technical specifications-including material, thickness, hole positioning, bending, terminal structure, surface treatment, and insulation solutions.

Copper-aluminum connections require selecting the appropriate process based on product structure, connection location, and operating environment. Key factors such as the connection interface, thermal cycling performance, mechanical strength, and contact reliability are strictly controlled to avoid relying on simple mechanical connections for dissimilar metals.

We recommend providing product drawings or 3D models, busbar material, current and voltage specifications, mounting method, surface treatment, insulation requirements, sample quantities, and estimated annual demand. If certain parameters are not yet finalized, you can provide existing structural data, and our engineering team will assist in evaluating the solution.
