Abstract

A power supply device including: (a) a power supply unit group composed of a plurality of power supply units and connected with a power consuming appliance; and (b) a control device configured to control the power supply unit group, wherein the control device and each of the power supply units are connected to each other by a communicating circuit.

Claims

1. A power supply device comprising:

(a) a power supply unit group composed of a plurality of power supply units and connected to a power generating device; and

(b) a control device configured to control the power supply unit group, the control device having a display device and a selecting device, wherein

the display device displays a state of power generation of the power generating device and a state of charge and discharge of each of the power supply units, and

on a basis of a selection from the selecting device, the control device selects a power supply unit to supply power from the power generating device to the selected power supply unit and charge the power supply unit.

2. The power supply device according to claim 1, wherein the power generating device and the power supply unit group are connected to each other via a radio power transmission circuit.

7. The power supply device according to claim 1, further comprising

a portable terminal including a display device,

wherein the control device and the portable terminal are connected to each other by a communicating circuit.

8. The power supply device according to claim 7, wherein mutual authentication is performed between the control device and the portable terminal at a time of connection, a cryptographic key is shared between the control device and the portable terminal, and communication encrypted by the cryptographic key is performed between the control device and the portable terminal.

3. A power supply device comprising:

(a) a power supply unit group composed of a plurality of power supply units and connected with a power consuming appliance; and

(b) a control device configured to control the power supply unit group, the control device having a display device and a selecting device, wherein

the display device displays a state of power consumption of the power consuming appliance and a state of charge and discharge of each of the power supply units, and on a basis of a selection from the selecting device, the control device selects a power supply unit to supply power from the selected power supply unit to the power consuming appliance.

4. The power supply device according to claim 3, further comprising

a power generating device connected to the power supply unit group, wherein

the display device displays a state of power generation of the power generating device, and

the control device selects a power supply unit on a basis of a selection from the selecting device to supply power from the power generating device to the selected power supply unit and charge the power supply unit.

5. The power supply device according to claim 4, wherein the power generating device and the power supply unit group are connected to each other via a radio power transmission circuit.

6. A power supply device comprising:

(a) a power supply unit group composed of a plurality of power supply units; and

(b) a control device configured to control the power supply unit group, the control device having a display device and a selecting device, wherein

the display device displays a state of charge and discharge of each of the power supply units, and

on a basis of a selection from the selecting device, the control device selects a power supply unit to output power and a power supply unit to receive power, and makes power transferred from the selected power supply unit to output power to the selected power supply unit to receive power.
