Abstract
An apparatus for wireless charging includes a charger, a wireless transmitting controller and a transmitting coil. The charger is configured to output a first voltage to the wireless transmitting controller. The wireless transmitting controller is configured to boost the first voltage to obtain a second voltage, and the second voltage is greater than the first voltage. The transmitting coil is configured to perform a wireless charging capability output at the second voltage. A terminal includes a wireless receiving coil, a wireless receiving controller and a step-down processor. The wireless receiving coil receives the charging signal from an apparatus for wireless charging. The wireless receiving controller processes the charging voltage to obtain a third voltage of direct current; and the step-down processor steps down the third voltage to obtain a fourth voltage within a charging range acceptable by the terminal and charge a battery of the terminal by the fourth voltage.
