| Abstract Scope |
The increased adoption of EVs is predicted to dramatically increase energy usage in the near future. There is therefore a critical need to overhaul transmission and distribution infrastructure to handle complex challenges related to power generation and peak load capacities. Overhead conductor networks in particular need to be upgraded with ultra-conductor materials, and are typically rated for their performance in terms of ampacity. In this presentation, the adopted ampacity models are discussed, along with performance improvements measured in bulk scale (3-m long, Ø2.5 mm) aluminum-graphene composite wires manufactured through Shear Assisted Processing and Extrusion (ShAPE). We observed an increase in ampacity in AA1100-graphene composite samples, through achieving a combination of low temperature coefficient of resistance and high electrical conductivity. Microstructural analysis will be discussed to explore graphene morphology and texture evolution which contributed to high ampacity characteristics. |
