Fig. 5 shows an example of this.

The control unit 209 of the portable telephone device 209 checks the connection of the non-contact charger 100 when it is detected that the charging voltage (or charging current) is supplied from the non-contact charging unit 201 to the power switching unit 202 And determines the state of charge of the internal battery 210 from the level detector 205.

If the internal battery 210 is not in the buffered state, the power switching unit 202 is controlled to set the charging path to the internal battery 210.

The power supply switching unit 202 supplies the charging voltage supplied from the non-contact charging unit 201 to the internal battery 210 to charge the internal battery 210.

When the internal battery 210 is in a buffered state, it is determined whether the external battery 300 is connected. When the external battery 300 is connected, the external battery 300 is charged .

The external battery connection detecting unit 204 senses the external battery 300 connected to the connection interface unit 203 and provides the external battery 300 to the controller 209. The controller 209 firstly charges the internal battery 210 And then the external battery 300 is charged.

That is, the power supply switching unit 211 sets the power supply switching path so that the voltage of the internal battery 210 is normally supplied to the circuit unit 211. When the external battery 300 is connected, A used power switching path is set so as to be provided to the circuit portion 211. [

At this time, when the used power is switched from the internal battery 210 to the external battery 300 or when the used battery is switched from the external battery 300 to the internal battery 210, an intermittent interval (for example, 0.1 second) Power is required in the intermittent interval.

The controller 209 supplies the voltage charged in the intermittent power supply unit 208 to the power switching unit 202 so that the intermittent power can be supplied to the circuit unit 2110. [

When the power supply is normally performed after the intermittent interval has elapsed, the control unit 209 controls the external power supply unit 208 through the power switching unit 202 to connect the external battery 300 or the internal battery 210, And the power consumed in the intermittent interval is recharged.
