Abstract

A power generation amount output device configured to output a power generation amount of a photovoltaic panel having been installed in a vehicle to a display unit, includes a power generation amount obtainment unit configured to obtain the power generation amount of the photovoltaic panel; a fluctuation reduction unit configured to reduce a fluctuation of the power generation amount to be output by the display unit, depending on a vehicle state of the vehicle; and a power generation amount output unit configured to output the power generation amount having the fluctuation reduced by the fluctuation reduction unit to the display unit.

Claims

1. A power generation amount output device, configured to output a power generation amount of a photovoltaic panel having been installed in a vehicle to a display unit, comprising:

a power generation amount obtainment unit configured to obtain the power generation amount of the photovoltaic panel;

a fluctuation reduction unit configured to reduce a fluctuation of the power generation amount to be output by the display unit, depending on a vehicle state of the vehicle; and

a power generation amount output unit configured to output the power generation amount having the fluctuation reduced by the fluctuation reduction unit to the display unit.

2. The power generation amount output device, as claimed in claim 1, wherein the fluctuation reduction unit applies a fluctuation check process to the power generation amount obtained by the power generation amount obtainment unit, to suppress the fluctuation of the power generation amount,

wherein the power generation amount output unit outputs the power generation amount having the fluctuation check process applied by the fluctuation reduction unit to the display unit.

3. The power generation amount output device, as claimed in claim 1, wherein the fluctuation reduction unit reduces the fluctuation of the power generation amount to be output by the display unit, by lengthening a cycle to obtain the power generation amount by the power generation amount obtainment unit, or by lengthening a cycle to output the power generation amount obtained by the power generation amount obtainment unit to the display unit.

4. The power generation amount output device, as claimed in claim 1, wherein the fluctuation reduction unit obtains vehicle speed information of the vehicle as the vehicle state, to reduce the fluctuation of the power generation amount to be output by the display unit more when the vehicle speed is higher.

5. The power generation amount output device, as claimed in claim 1, wherein the fluctuation reduction unit obtains vehicle speed information of the vehicle as the vehicle state, and if the vehicle speed is greater than or equal to a reference value, reduces the fluctuation of the power generation amount to be output by the display unit.

6. The power generation amount output device, as claimed in claim 1, wherein the fluctuation reduction unit obtains positional information of the vehicle as the vehicle state, and if a current position of the vehicle indicates that the vehicle is traveling in a place other than predetermined places, reduces the fluctuation of the power generation amount to be output by the display unit.

7. The power generation amount output device, as claimed in claim 1, further comprising:

a travel state determination unit configured to determine a travel state of the vehicle from operational information of an operational member operated by a driver,

wherein if it is not determined by the travel state determination unit that it is the travel state where the vehicle is traveling at the vehicle speed less than or equal to a predetermined value, the fluctuation reduction unit reduces the fluctuation of the power generation amount to be output by the display unit.

8. A photovoltaic system, including

a photovoltaic panel,

a display unit, and

a power generation amount output device configured to output a power generation amount of the photovoltaic panel,

comprising:

a power generation amount obtainment unit configured to obtain the power generation amount of the photovoltaic panel;

a fluctuation reduction unit configured to reduce a fluctuation of the power generation amount to be output by the display unit, depending on a vehicle state of a vehicle; and

a power generation amount output unit configured to output the power generation amount having the fluctuation reduced by the fluctuation reduction unit to the display unit.

9. A power generation amount output device, including

a display unit, and

a power generation amount output unit configured to output a power generation amount of a photovoltaic panel having been installed in a vehicle to the display unit,

comprising:

a power generation amount obtainment unit configured to obtain the power generation amount of the photovoltaic panel;

a fluctuation reduction unit configured to reduce a fluctuation of the power generation amount to be output by the display unit, depending on a vehicle state of a vehicle; and

a power generation amount display unit configured to have the display unit display the power generation amount having the fluctuation reduced by the fluctuation reduction unit.
