To address the global concerns regarding climate changes and increase of earth temperature, carbon dioxide emission has to be reduced/removed. A major source of Co2 emission is transportation vehicles, which account for close to 30% of Canada's greenhouse gas emissions. An active method to reduce this significant contribution to global warming is electrification of transportation vehicles. Battery operated vehicles are the cornerstone of automotive electrification. To improve the efficiency and safety of the batteries in electric vehicles, structural durability of them must be maintained. This project studies the requirements for structural soundness of major weld/joints in a typical battery packs. The joints that are considered in this study include battery terminal to battery connection tabs, new lead-free solder joints, and seam weld used on the housing of battery cells and battery packs. Results will be implemented by Stellantis to expand their adaptation of battery electric vehicles.

为了解决全球对气候变化和地球温度升高的关注，必须减少/去除二氧化碳的发射。二氧化碳排放的主要来源是运输车辆，占加拿大温室气体排放量的近30％。减少对全球变暖的重要贡献的一种主动方法是运输车辆的电气化。电池操作的车辆是汽车电气化的基石。为了提高电池电池在电动汽车中的效率和安全性，必须保持其结构耐用性。该项目研究了典型的电池组中主要焊接/关节结构性声音的要求。本研究中考虑的关节包括电池连接选项卡，新的无铅焊点以及用于电池电池和电池组的壳体焊缝。结果将由Stellantis实施，以扩大电池电动汽车的适应。
