Development of an Energy Recovering Eddy Current Braking system for Sustainable Electric Vehicles

Abstract

This study explores a new eddy current braking (ECB) system designed to recover part of the energy typically lost as heat during braking. While conventional brakes and traditional ECBs waste kinetic energy and regenerative braking in EVs is less effective at high speeds, the proposed hybrid ECB concept targets this gap by enabling energy harvesting where ECBs perform best. The research analyzes electromagnetic design, material choices, thermal behavior, and simulation methods to identify practical ways to convert braking losses into usable energy. It also reviews current, limited ECB energy-recovery approaches and introduces a design that preserves ECBs’ durability, simplicity, and non-contact operation while enabling realistic energy recapture.2025
