This article explores the role of oval nanocrystalline cores in the advancement of New Energy Vehicles (NEVs). It discusses the unique properties of these materials, such as high permeability, low core loss, and excellent thermal stability, and how they translate into significant technological advantages for EVs and hybrids. Key benefits include faster response times, reduced electromagnetic interference (EMI), and improved cost-effectiveness, ultimately contributing to the development of more efficient and reliable electric vehicles.

Amorphous nanocrystalline soft magnetic alloy has the performance advantages of high saturation magnetic induction strength, high permeability and low loss, which is an ideal soft magnetic material for industrial frequency and low and medium frequency electronic and electrical applications, and its application can promote the development of products in the direction of energy-saving, high efficiency, miniaturisation and quietening.

The rapid development of charging piles, vehicle chargers and vehicle DC/DC converters has also promoted the wide application of high-performance soft magnetic materials (including amorphous nanocrystalline alloys and magnetic powder cores).

Traditional cores are made of ordinary ferrite, however, with the continuous progress of science and technology, amorphous cores gradually appeared, compared with traditional cores, amorphous cores due to the saturation density is much higher than ordinary ferrite cores, and low loss, small size and is favoured by many people.

This article introduces the application characteristics of amorphous (nanocrystalline) materials and the potential issues encountered in practical use, particularly in the applications of magnetic cores, transformers, and inductors.

Amorphous Cores are made to be used in diverse applications owing to their low connectivity, low loss, and higher vulnerability. Some of the most common applications of their usage include:
