Various examples are provided related to wireless charging of electric vehicles. In one example, a wireless charging system includes a transmitter pad including a primary coil supplied by a power source, and alignment control circuitry configured to determine an alignment condition of the transmitter pad with respect to a receiver pad of an electric vehicle. In another example, a wireless charging system includes a receiver pad including a secondary coil; and alignment processing circuitry configured to determine an alignment condition of the receiver pad with respect to a transmitter pad comprising a primary coil supplied by a power source. In another example, a method includes measuring output voltages of a plurality of auxiliary coils mounted on a secondary coil located over a primary coil of the wireless charging system and determining a lateral misalignment between the primary and secondary coils using the output voltages.
