Abstract

The movable component for a network system may communicate with another component. The movable component includes a body, a battery, a control unit, and a communication unit. The body includes a wheel for moving, and a motor driving the wheel. The battery supplies a power to the motor. The communication unit communicates with the other component to receive information related to energy. The control unit determines whether to charge the battery based on the information related to energy.

Claims

1. A movable component for a network system which communicates with another component, the movable component comprising:

a body comprising a wheel to move;

a motor to drive the wheel;

a battery to supply a power to at least the motor;

a communication unit to communicate with another component, the communication unit to receive information related to energy; and

a control unit to receive the information related to the energy from the communication unit, wherein the control unit determines whether to charge the battery based on the information related to energy,

wherein when the information related to energy indicates a low-cost energy period, the control unit causes a charging amount per unit time of the battery to increase during at least a portion of the low-cost energy period.

8. The movable component according to claim 1, further comprising a release button, wherein:

when the information related to energy indicates a low-cost period, the control unit causes a charging amount per unit time of the battery to increase during at least a portion of the low-cost energy period, and

when a release button is used, the control unit causes the charging amount per unit time of the battery to be maintained identically to a period previous to the low-cost energy period.

9. The movable component according to claim 1, wherein the information related to energy comprises information to notify whether to charge the battery indicating a low-cost energy period.

10. The movable component according to claim 9, wherein when the control unit receives a charging command the control unit performs charging of the battery.

11. The movable component according to claim 9, wherein when the control unit does not receive a charging command within a certain time, whether to charge the battery is determined according to remaining charged amount of the battery.

12. The movable component according to claim 1, wherein control unit charges the battery using a power from an other component.

13. The movable component according to claim 1, wherein control unit supplies a power from the battery to the other component.

14. The movable component according to claim 13, wherein the other component is an energy consumption component which consumes energy.

15. The movable component according to claim 1, wherein when the information related to energy indicates a low-cost energy period, the control unit causing the motor to drive the wheel to a battery charging component to charge the battery.

16. The movable component according to claim 1, wherein when the information related to energy indicates a low-cost energy period, the control unit determines whether the battery needs to be charged, and if the control unit determines that the battery needs to be charged, the control unit causing the motor to drive the wheel to a battery charging component to charge the battery.

17. The movable component according to claim 1, wherein when the information related to energy indicates a high-cost energy period and the control unit determines that the battery needs to be charged, the control unit causing the movable component to stop operation and not charging the battery.

18. The movable component according to claim 1, wherein when the information related to energy indicates a high-cost energy period, the control unit causing the motor to drive the wheel to an energy consumption component to supply a power to the energy consumption component.

19. The movable component according to claim 18, wherein the control unit determines which energy consumption component to supply the power among the plurality of energy consumption components based on a priority of the energy consumption components.

2. A movable component for a network system which communicates with another component, the movable component comprising:

a body comprising a wheel to move;

a motor to drive the wheel;

a battery to supply a power to at least the motor;

a communication unit to communicate with another component, the communication unit to receive information related to energy; and

a control unit to receive the information related to the energy from the communication unit, wherein the control unit determines whether to charge the battery based on the information related to energy,

wherein when the information related to energy indicates a low-cost energy period, the control unit causes a charging amount per unit time of the battery to decrease or to be maintained during at least a portion of the low-cost energy period.

3. The movable component according to claim 2, wherein total usage cost expended in charging of the battery or total charged amount of the battery increases at the entire low-cost energy period.

4. A movable component for a network system which communicates with another component, the movable component comprising:

a body comprising a wheel to move;

a motor to drive the wheel;

a battery to supply a power to at least the motor;

a communication unit to communicate with another component, the communication unit to receive information related to energy; and

a control unit to receive the information related to the energy from the communication unit, wherein the control unit determines whether to charge the battery based on the information related to energy,

wherein when the information related to energy indicates a low-cost energy period, the control unit causes a charging amount per unit time of the battery to be maintained during at least a portion of the low-cost energy period.

5. The movable component according to claim 4, wherein:

when charging of the battery is not yet performed, charging of the battery is not continuously performed, and

when charging of the battery is being performed, the charging amount per unit time of the battery is maintained.

6. The movable component according to claim 4, wherein total usage cost expended in charging of the battery or total charged amount of the battery increases at the entire low-cost energy period.

7. The movable component according to claim 4, wherein when the low-cost energy period corresponds to an unallowable period, the charging amount per unit time of the battery is maintained.
