Design and Fabrication of Auto-Charging Electric Car Using Electromagnetic Induction

Abstract

This journal paper emphasizes the design and fabrication of an auto charging system for electric vehicle using electromagnetic induction for efficient power generation & charging is presented. The system we have proposed contains all the major components (BLDC motor, Controller and Li-ion battery) that are necessary for energy maximization and also for the functionality. The electric vehicle can produce electricity whilst moving by the electromagnetic induction principle, i.e. charging the battery without using a separate charger infrastructure. This method is intended to scale and improve the efficiency of electric vehicles making it a robust alternative for minimizing reliance on conventional infrastructure to charge. The design, operation and performance of the system are elaborated with experimental results indicating the viability to applications in practice with different auto charging configurations .The shaft can generate electricity if it gets magnetized which can be used to power other components. A vehicle such as this can generate electricity for operating a hybrid engine or recharging batteries by use of an electricity generating shaft. The electricity generating shaft consists of a magnetized driveshaft which acts as a rotor, and a series of copper wire coils surrounding the magnetized driveshaft which acts as a stator in an electrical generator. In this project, we will use the shaft, which rotates at high speed, on which we will mount the disc magnet and the plates to hold the coils near the magnets mounted on the rotating shaft. This rotational movement creates a magnetic field and generates EMF into the coil, as defined by Faraday's law of electromagnetic inductions.
