Abstract

Battery information output equipment allows a driver of an electric vehicle 10 of an electricity consumer 2 , now parked, to input what battery capacity is required at two or more points of time on or before the time at which the electric vehicle is scheduled to come into use, considering an operation schedule for the vehicle, and transmits the usable capacity at each point of the times, i.e., maximum capacity minus capacity required at each point of the times, to a power supply/demand management center 3 , so that charge and discharge of a battery 17 is controlled by a charge/discharge command from the power supply/demand management center 3 such that use of battery capacity for power supply and demand leveling is kept within the usable capacity at any point of the times.

First claim

The invention claimed is:

1. Battery information output equipment for a power supply and demand leveling system in which electric power is supplied from an electricity utility to electricity consumers via distribution lines, and when an electric vehicle of an electricity consumer is parked and connected to the distribution lines, a charge/discharge command relevant to a batter of the electric vehicle is transmitted from a power supply/demand management device to the electricity consumer on the basis of power supply/demand information transmitted from the electricity utility to control charge and discharge of the battery of the electric vehicle for power supply and demand leveling by using a charge/discharge controller, the battery information output equipment comprising:
an input device for inputting plural times after the electric vehicle is connected to the distribution lines and a usable capacity of the battery at each point of the times for power supply and demand leveling by controlling charge and discharge of the battery, by specifying two or more points in a coordinate system consisting of an axis of time and an axis of the usable capacity in an entire capacity of the battery using as an index a required capacity that is a battery capacity to be secured, considering the electricity consumer's operation schedule for the electric vehicle, and
an output device for transmitting the usable capacity at each point of the times inputted with the input device to the power supply/demand management device, wherein
the input device and the output device each being provided to at least either the electric vehicle or a place of the electricity consumer where the electric vehicle is parked.

2. The battery information output equipment according to claim 1 , wherein
the output device takes in an accumulated power limiting value to limit accumulated power supplied to and from the battery and transmits the accumulated power limiting value to the power supply/demand management device with the usable capacity at each point of the times.

3. The battery information output equipment according to claim 2 , further comprising:
a limiting-value correction device for correcting the accumulated power limiting value depending on duration of use of the battery, wherein
the output device transmits the accumulated power limiting value corrected by the limiting-value correction device.

4. The battery information output equipment according to claim 2 , further comprising:
a limiting-value correction device for correcting the accumulated power limiting value depending on temperature of the battery, wherein
the output device transmits the accumulated power limiting value corrected by the limiting-value correction device.

5. The battery information output equipment according to claim 1 , wherein
the output device takes in a maximum rate limiting value to limit maximum rate of power supplied to and from the battery and transmits the maximum rate limiting value to the power supply/demand management device with the usable capacity at each point of the times.

6. The battery information output equipment according to claim 5 , further comprising:
a limiting-value correction device for correcting the maximum rate limiting value depending on duration of use of the battery, wherein
the output device transmits the maximum rate limiting value corrected by the limiting-value correction device.

7. The battery information output equipment according to claim 5 , further comprising:
a limiting-value correction device for correcting the maximum rate limiting value depending on temperature of the battery, wherein
the output device transmits the maximum rate limiting value corrected by the limiting-value correction device.
