Wireless energy transfer or wireless power is the transmission of electrical energy from a power source to an electrical load without a conductive physical connection. Wireless transmission is useful in cases where interconnecting wires are inconvenient, hazardous, or impossible. The problem of wireless power transmission differs from that of wireless telecommunications, such as radio. In the latter, the proportion of energy received becomes critical only if it is too low for the signal to be distinguished from the background noise. With wireless power, efficiency is the more significant parameter.  A large part of the energy sent out by the generating plant must arrive at the receiver or receivers to make the system economical. The most common form of wireless power transmission is carried out using direct induction followed by resonant magnetic induction.   This project proposes a wireless power transmission system for electric vehicles (EVs) using a comprehensive setup. At the transmission side, a step-down transformer, rectifier, capacitive bank, and copper coil are utilized to efficiently transfer power wirelessly. The transmitter generates a magnetic field that induces a current in a receiving copper coil located in the EV. At the receiving side, the induced current is rectified and controlled by a microcontroller, which interfaces with a voltage sensor and an LCD display. This system aims to provide a convenient and efficient method for charging EVs without the need for physical connections.
