Abstract
A multimedia terminal device for high-speed charging that allows for high-speed charging of a portable electronic device connected to a multimedia terminal and a method of controlling the same are provided. The multimedia terminal device includes a power converter that is configured to convert a voltage from a battery to a voltage for the high-speed charging and to supply the converted voltage to the multimedia terminal. In addition, a switching circuit is configured to select a high-speed charging mode when an engine is driven and a low-speed charging when the engine is stopped.
Claims7
A multimedia terminal for high-speed charging, comprising:
- a power converter configured to convert a voltage from a battery into a high-speed charging voltage;
- a connecting terminal to which an external smart device is connected to charge the external smart device;
- a first controller configured to supply a low-speed charging voltage;
- and
- a charging controller configured to determine a low-speed charging mode and a high-speed charging mode of the external smart device based on whether an engine is driven to supply the low-speed charging voltage or the high-speed charging voltage to the connecting terminal.
A method of controlling a high-speed charging multimedia terminal device, comprising:
- converting, by a power converter, a voltage of a battery into a high-speed charging voltage;
- selecting, by a switching circuit, a charging mode of determining a high-speed charging mode and a low-speed charging mode based on whether an engine is driven or stopped;
- performing, by a charging controller, a high-speed charging mode by supplying the high-speed charging voltage converted by the power converter to a connecting terminal;
- and
- performing, by the charging controller, the low-speed charging mode by supplying the low-speed charging voltage from a first controller to the connecting terminal when the engine is stopped.
