Development of a new battery casing for electric vehicles using 3D printing

NSERC/通用电气/Dyze设计联盟资助蒙特利尔理工大学教授Étienne Martin使用3D打印技术开发电动汽车的新电池外壳。该赠款将重点开发两种类型的数字工具，以帮助设计使用粘合剂喷射增材制造和长丝沉积建模制造的部件。这些工具将用于为我们的工业合作伙伴开发用于电动汽车的电池外壳的新颖设计。第一个数值工具是烧结补偿工具，其将允许从打印几何形状预测最终烧结几何形状。第二个工具包括优化框架，它将使使用人工智能设计电池外壳等组件成为可能，应用于增材制造（AM）促进的无约束设计空间。该项目的成果将使加拿大制造商能够生产新的增材制造部件，这些部件更轻，并具有额外的功能。这些部件的设计和生产将使加拿大处于AM生产的最前沿。开发带有集成冷却系统的电动汽车电池外壳将增加加拿大电动汽车的续航里程和可靠性。该项目与2014年加拿大科学和技术战略相一致，以应用AM和减少绿色房屋气体排放，这是运输行业的目标。

Development of a new battery casing for electric vehicles using 3D printing The NSERC/General Electric/Dyze Design Alliance grant, in development of a new battery casing for electric vehicles using 3D printing, is to be held by Polytechnique Montréal professor Étienne Martin. The grant will focus on the development of two types of numerical tools to aid in the design of components manufactured using binder jet additive manufacturing and filament deposition modelling. These tools will be used to develop novel designs for battery casings to be used in electric vehicles for our industrial partners. The first numerical tool is a sintering compensation tool, which will allow prediction of the final sintered geometries from the print geometries. The second tool includes optimization frameworks, which will enable the design of components such as battery casings using artificial intelligence, applied to the unconstrained design space facilitated by additive manufacturing (AM). The outcomes of this project will allow Canadian manufacturers to produce new AM parts, which are lighter and possess additional functionalities. The design and production of these parts will allow Canada to be at the forefront of AM production. The development of electric vehicle battery casings with integrated cooling systems will enable increased range and reliability of operational electric vehicles in Canada. This project is aligned with the 2014 Canadian Science and Technology Strategy for the application of AM and reduction of green house gas emissions, which is a goal of the transportation industry.
