Power supply system, electric vehicle and charging adapter
First Claim
1. A power supply system that supplies charging power to an electric vehicle equipped with an electric storage device as well as electric power to another electric apparatus, the power supply system comprising:
- a power adjustment unit that increases and decreases charging power to be supplied to the electric storage device based on an operation state of the electric apparatus,wherein, the power adjustment unit has, as a charging mode, a first charging mode in which the electric storage device is charged with first charging power, a second charging mode in which the electric storage device is charged with second charging power smaller than the first power, and a third charging mode in which the electric storage device is charged with third charging power larger than the first power;
wherein, when power consumption of the electric apparatus exceeds a predetermined value, the power adjustment unit switches the charging mode from either one of the first charging mode and the third charging mode to the second charging mode so as to decreases charging power to be supplied to the electric storage; and
wherein, when receiving operation scheduling information of the electric apparatus, the power adjustment unit switches the charging mode from either one of the first charging mode and the second charging mode to the third charging mode so as to increase charging power to be supplied to the electric storage device.

Abstract
There are provided a power supply system, an electric vehicle and a charging adapter. Electric power from a commercial power supply is distributed to electric lines by way of a distribution board and provided to electric apparatuses and an electric vehicle from the electric lines. When power consumption of electric apparatuses exceeds a predetermined value upon charging the electric vehicle, charging power to be supplied to the electric vehicle is decreased. Decreasing the charging power to the electric vehicle can avoid the restriction of the use of the electric apparatuses, thereby improving user'"'"'s satisfaction.

2. The power supply system according to claim I, further comprising:
-
a time calculator that calculates a charging time until the electric storage device reaches to a predetermined charge state based on charging power supplied to the electric storage device; and a time display that displays a charging time calculated by the time calculator on a display device, wherein the time display continues to display a currently displayed charging time on the display device until a charging time that is longer than the currently displayed charging time by a predetermined value is calculated.

3. An electric vehicle that, when in use, is connected to a power supply system supplying electric power to an electric apparatus, the electric vehicle comprising:
-
an electric storage device charged with charging power supplied from the power supply system, wherein the electric vehicle includes a power adjustment unit that increases and decreases charging power to be supplied to the electric device based on an operation state of the electric apparatus; wherein, the power adjustment unit has, as a charging mode, a first charging mode in which the electric storage device is charged with first charging power, a second charging mode in which the electric storage device is charged with second charging power smaller than the first power, and a third charging mode in which the electric storage device is charged with third charging power larger than the first power; wherein, when power consumption of the electric apparatus exceeds a predetermined value, the power adjustment unit switches the charging mode from either one of the first charging mode and the third charging mode to the second charging mode so as to decrease charging power to be supplied to the electric storage device while maintaining the operation state of the electric apparatus; and wherein, when receiving operation scheduling information of the electric apparatus, the power adjustment unit switches the charging mode from either one of the first charging mode and the second charging mode to the third charging mode so as to increase charging power to be supplied to the electric storage device. - View Dependent Claims (4)
