Abstract

Electric vehicle being one of the leading green technologies nowadays, is leaving a humongous amount of spent lithium-ion batteries untreated. Current research on lithium-ion battery waste management is at its minimal because the huge power range of the battery is much attractive than the battery waste dismantling process. Treating these battery wastes are crucial for rare metal recovery due to its limited resources on land. Thus, this study aims to propose an eco-design battery pack to ease the recycling process in a more economical and sustainable manner. SolidWorks is used to generate the 3D modelling and ANSYS is utilized to carry out the simulation of the product’s mechanical performance in a drop and impact tests. Results shows that the proposed design of EV battery pack has a design efficiency of one with Easy Fixings indicator of 28%. In the drop test of 0.3 m height, it yields a maximum deformation of 1.015e−3m and a generated Von-Mises stress of 4.827e 8N/m2. Other than that, 2.5227e6 N/m2 of Von-Mises stress is obtained in the impact frontal test. With a great impact of cruising at a speed of 15.6464 m/s, 5.6053e−8 m deformation is obtained in the same test. As a result, the proposed EV battery pack design has showed the potential to improve the sustainability, performance, and ease of disassembly.
