Abstract

An apparatus of charging an electric mobility may include a tire wheel having an external surface configured to be coupled to a tire and an internal surface in which an empty space is formed, a battery accommodated in the empty space of the internal surface of the tire wheel and mounted, like the tire wheel, on a rotation shaft fixed to the tire wheel to be rotationally driven, a stopper configured to selectively couple the battery to the rotation shaft, and a controller connected to the stopper and configured to control selective coupling of the rotation shaft to the battery by the stopper, wherein the stopper is controlled by the controller so that the battery is charged using an induced electromotive force generated between a coil wound on the battery and a permanent magnet which is mounted to face the battery.

Claims

1. An apparatus of charging an electric mobility, the apparatus comprising:

a tire wheel having an external surface configured to be coupled to a tire and an internal surface in which an empty space is formed;

a battery accommodated in the empty space of the internal surface of the tire wheel and mounted on a rotation shaft fixed to the tire wheel to be rotationally driven;

a stopper configured to selectively couple the battery to the rotation shaft; and

a controller connected to the stopper and configured to control selective coupling of the rotation shaft to the battery by the stopper,

wherein the stopper is controlled by the controller so that the battery is charged using an induced electromotive force generated between a coil wound on the battery and a permanent magnet which is mounted to face the battery.

2. The apparatus of charging the electric mobility of claim 1,

wherein, when the electric mobility is driving, the controller is configured to control the stopper to couple the battery to the rotation shaft.

3. The apparatus of charging the electric mobility of claim 1,

wherein, when the electric mobility is braked, the controller is configured to control the stopper to decouple the battery from the rotation shaft.

4. The apparatus of charging the electric mobility of claim 1,

wherein the permanent magnet is inserted and mounted in the tire wheel to face the battery.

5. The apparatus of charging the electric mobility of claim 1,

wherein the permanent magnet is positioned between the internal surface of the tire wheel and an external surface of the battery as a rotor of the apparatus and mounted to a flange fixedly connected to the tire wheel and the rotation shaft.
