Modern Electric Vehicles have a drawback of long charging time, bulk battery packs, short lifetime etc. This can be rectified by using dynamic wireless charging. The paper discusses about the dynamic wireless charging and its prototype. Dynamic wireless charging uses magnetic resonance for transmitting power. AC power from grid is converted to DC using a rectifier, this DC is then converted to high frequency AC using a power inverter. This high frequency AC is supplied to transmitting coils laid under the road. This high frequency AC produces resonating magnetic field on the transmitting coil. The receiving-end coil under the electric vehicle picks up the magnetic field and the induced emf is supplied to a rectifier. The rectified output is given to motor and battery on the vehicle. This method is an efficient approach to provide charging plans for electric vehicles from a global point of view, without overloading of electric system and reduce the charging time.
