Title: Induktiv laddning av batteridrivna fordon under drift
Authors: Eriksson, Andreas

Abstract: The interest and development of electric cars has increased greatly in the recent years. Many people choose to buy electric cars instead of traditional cars with a combustion engine. But the electric car is still limited with a relative short travel distances and long loading times, both of these traits needs to be developed in order to make the electric car more competitive. One of the greatest advantages of the electric car is the environmental aspect; electrical cars contribute less than cars with combustion engines to the emission of greenhouse gases. The project aims to develop an inductive charging technology for battery-powered vehicles while driving, a technology that can decrease the negative traits of charging and travel distances since the car would be charged during driving. The project resulted in a circuit where both a battery could be charged and the engine could be operated simultaneously by energy transmitted wireless from a primary circuit and a system to control the coils used to transmit the energy. The circuit constructed consisted of a primary circuit with an oscillator, amplifier, and a primary coil. The primary circuit transfer energy to a secondary circuit which then charges the battery and runs the engine. The secondary circuit consists of a secondary coil, diode bridge and a voltage regulator. After the voltage regulator a motor and a battery control unit which charges a battery was connected. The control system was constructed of an Arduino Uno, a relay card and distance sensors. The distance sensors send signals depending of the distance from the secondary coil to the primary coil to the Arduino. These signals are processed by the Arduino, the Arduino then sends signals to the relay card which controls the feeding of energy to the primary coils. The project was carried out at the Department of Computer Science and Engineering at Chalmers University of Technology.
