The project aims at developing an intelligent Electric vehicle which is powered from wireless power transmission. In transmission section we are using hybrid power such as solar, wind, transformer to charge the battery which is used to provide the power supply of the transmitting coil. In receiver section consist of vehicle. This vehicle receives the power from transmitting coil while moving the vehicle. By using control buttons, we can control the vehicle which is connected with battery along with DC motors by using wireless power transmission. Achieving balance between power consumption and power production is a bigger challenge today. The best way to solve this imbalanced equation is to use solar energy as efficiently as possible. The problem in the usage of solar energy is with solar cell panel should be exposed maximum to the sun light. If the solar panel is fixed in a particular direction, then the sun light intensity varies from morning to evening. Moving the solar cell panel in the direction of sun can increase the solar energy generated from the solar cell. 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. The project consists of two self resonating copper coils of same resonating frequency generator. One copper wire is connected to the power source (transmitter), while the other copper wire is connected to the device (receiver).the electric power from the power source causes the copper coil connected to it to start oscillating at a particular frequency. Subsequently, the space around the copper coil gets filled with nonmagnetic radiations. This generated magnetic field further transfers the power to the other copper coil connected to the receiver. Since this coil is also of the same frequency, it starts oscillating at the same frequency as the first coil. This is known as 'coupled resonance' and is the principle of tesla. This project results in a device where the electricity is transmitted wirelessly through copper coils for a distance. The system uses frequency generator at the transmitter circuit. Therefore, the current flows from the coil on the transmitter side to the receiver side coil wirelessly connected with rectifier and regulator. The output of the regulator is given to the battery charging circuit and from it to the Electric vehicle. This project results in a device where the electricity is transmitted wirelessly through copper coils for a distance range of about 10 cm. The system uses solar energy and pulse generator of 100 KHZ at the transmitter circuit. Therefore, the current flows from the coil on the transmitter side to the receiver side coil wirelessly connected with rectifier which converts AC voltage to DC voltage and this DC voltage is given to the battery for charging.
