A common problem in wireless charging systems in automotive applications is alignment of the wireless power transfer transmitter and receiver units. Poor alignment leads to poor power transfer capacity and a longer charging time. Costly optical sensors and electromechanical systems may be employed to align the transmitter and receiver units. A solution to this problem is to employ a freely moveable wireless power transmitter in at least one direction that is magnetically attracted to the wireless power receiver unit in the vehicle that does not require electrically powered sensors or mechanical alignment systems.
