Abstract

Disclosed herein is a charging device including: a power supply section adapted to supply power from a power source to external equipment; a control section adapted to activate the power supply section; and an activation section adapted to activate the power supply section if the control section is not activated.

Claims

1. A charging device comprising:

a power supply section adapted to supply power from a power source to external equipment;

a control section adapted to activate the power supply section; and

an activation section adapted to activate the power supply section if the control section is not activated.

2. The charging device of claim 1, wherein

the power supply section is activated by receiving an enable signal from either the control section or the activation section.

3. The charging device of claim 2 further comprising:

an OR circuit adapted to output an enable signal, received from the control section or the activation section, to the power supply section.

4. The charging device of claim 1, wherein

the activation section activates the power supply section in response to a user input.

5. The charging device of claim 2, wherein

the activation section activates the power supply section by supplying an enable signal for a given period of time in response to supply of power from the power source.

6. The charging device of claim 1 further comprising:

a voltage conversion section adapted to convert the voltage of power from the power source to a given voltage and supply the power to the power supply section.

7. A control method of a charging device, comprising:

activating a power supply section adapted to supply power from a power source to external equipment if a control section adapted to activate the power supply section is not activated.

8. An electric-powered vehicle comprising:

a charging device including

a power supply section adapted to supply power from a power source to external equipment,

a control section adapted to activate the power supply section, and

an activation section adapted to activate the power supply section if the control section is not activated;

a converter being supplied with power from the power supply section and converting power into a driving force of the vehicle; and

a controller handling information processing relating to vehicle control based on information about the power supply section.

9. An energy storage device comprising:

a charging device including

a power supply section adapted to supply power from a power source to external equipment,

a control section adapted to activate the power supply section, and

an activation section adapted to activate the power supply section if the control section is not activated;

the energy storage device supplying power to electronic equipment connected to the power supply section.

10. A power system comprising:

a battery; and

a charging device including

a power supply section adapted to supply power from a power source to external equipment,

a control section adapted to activate the power supply section, and

an activation section adapted to activate the power supply section if the control section is not activated;

wherein

the battery supplies power, and is supplied with power from a generator or an electricity network.
