Tiivistelmä
Due to the issue related to climate change and excessive co2 emission automakers are moving towards Electromobility. Battery-pack, which is made up of thousands of cells joining together, is a source of power for the electric vehicle. Effective joining technology between the battery cell tab and Busbar enhances the overall electro-mechanical performance of the battery pack and eventually electric car. This thesis aims to Investigate the electrical performance of the Bimetallic Joint between the Battery cell tab and the Busbar.
Literature Review reveals different joining technologies used in the industries to join dissimilar materials for Battery cell tabs to busbar joining. The Resistance spot welding method is used in this Research to join the dissimilar materials by using Sunstone CDDP-A resistance spot welding machine. Experiments were conducted to check the weldability of Dissimilar different materials. A microanalysis of Welded Joint between Nickle and Nickle plated steel was done, and an electrical performance was evaluated.
