Today’s requirements on vehicles with internal combustion engine are characterized by more sophisticated emission regulations, rising fuel prices and higher driver’s demand on driving dynamic, comfort in line with increased environmental awareness. For that reason, more and more car manufacturers throughout the world are focusing on electric vehicles. The battery technology currently in use is lithium ion batteries because these are smaller and lighter than current automotive power batteries (generally, Nickel Metal Hydride). This technology can provide power equivalent to current technology at a smaller size and lighter weight, or more power at an equivalent size and weight. The batteries used in the electric vehicle batteries (EVB) are constructed from a combination of different materials and these materials pose particular challenges to be joined together. The battery has to operate safely and reliably for the whole of the life cycle stipulated by the vehicle manufacturer, and that is at least ten years. In this work, we will provide welding data for aluminium 3000 series, pure copper and joints between copper and aluminium alloy materials with fiber lasers.
