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

NSERC/通用电气/戴兹设计联盟为开发一种使用3D打印的电动汽车新型电池外壳而提供的赠款将由蒙特雷尔理工学院教授艾蒂安·马丁担任。赠款将侧重于开发两类数字工具，以协助设计使用粘结剂喷射剂制造和灯丝沉积造型制造的部件。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设计。第一个数值工具是烧结补偿工具，它将允许根据打印几何预测最终的烧结几何。第二个工具包括优化框架，它将使电池外壳等组件的设计能够使用人工智能，应用于由加法制造(AM)促进的不受限制的设计空间。该项目的成果将允许加拿大制造商生产新的AM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走在AM生产的前列。开发具有集成冷却系统的电动汽车电池外壳将使加拿大运营的电动汽车的续航里程和可靠性得到提高。该项目与2014年加拿大应用AM和减少温室气体排放的科学和技术战略保持一致，这是运输业的一个目标。

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.
