Electric
vehicles are seen as an alternative option given the scarcity of resources. In
order to increase the usage of EVs in daily life, convenient and reliable
methods of charging EV batteries are very important, so Wireless Power Transfer
(WPT) is being considered as a solution to charge the batteries. In this
project, prototype hardware for charging system with dual coils and operating
frequency of 60 kHz will be designed and implemented. Plug-in electric vehicles
(PEVs) are overwhelmed by the need for plug-in cables and chargers, the
galvanic isolation of the onboard electronics, the bulk and cost of this
charger, and the large assemblies of energy storage systems (ESS) required. But
through the use of wireless charging systems, wireless charging capability
offers customer convenience, inherent electrical isolation, grid-side
regulation, and reduces the size of onboard ESS through on-road dynamic
charging. The main goal of our project is to design and develop a vehicle-grade
antenna system that uses resonant magnetically-coupled wireless energy transfer
technology to EV charging system. The use of WPT in electric vehicles enables
clean, comfortable and safe operation. At the heart of WPT systems are primary
and secondary coils. These coils form a weakly coupled system where the
coupling coefficient is between 0.1 and 0.5. To transmit the rated power, both
sides must be tuned by resonance capacitors. The operating frequency is a
central selection criterion for all applications and particularly influences
the dimensioning of the coils and the selection of the components for the power
electronic circuit. A resonant wireless transmission system is designed for
vehicle charging technology.
