Abstract

A charged-amount display part displays a battery charge rate of an entire battery pack according to kinds of charge sources. An example of displaying the battery charge rate in the form of a bar chart is shown. A speed display part displays a vehicle speed of a running electric vehicle. The running cost display part displays a running cost calculated based on consumed electric power of the battery.

Claims

1. A charge display unit of a vehicle traveling by means of a motor being driven by using electric power charged in a battery as a drive source,

said charge display unit comprising a charged-amount display part that displays the charged amount in such a manner that in a case where said battery is charged by a plurality of charge sources, the charged amounts charged by the respective charge sources can be separately displayed.

2. The charge display unit according to claim 1, wherein

said charged-amount display part displays the charged amount in such a manner that the area of a display region corresponding to, among said plurality of charge sources, a charge source charging said battery can be increased.

3. The charge display unit according to claim 1, wherein

in a case where electric power of said battery charged by a plurality of charge sources is consumed, said charged-amount display part displays the charged amount in such a manner that the areas of display regions corresponding to said respective charge sources can be decreased at the same rate as that of the consumed electric power.

4. The charge display unit according to claim 1, wherein

in a case where said battery is charged by a plurality of charge sources, said charged-amount display part sequentially arranges display regions in the order of electric power costs of said respective charge sources.

5. The charge display unit according to claim 1, wherein

in a case where said battery is charged by a plurality of charge sources, said charged-amount display part displays the charged amount in such a manner that display regions can be gradually shaded in the order of electric power costs of said respective charge sources.

6. The charge display unit according to claim 1, wherein

said vehicle includes a hybrid vehicle that generates electric power by an engine and stores the generated electric power in said battery,

the electric power generated by said engine serves as one of charge sources.

7. A charge display unit of a vehicle that travels by means of a motor being driven by using electric power charged in a battery as a drive source,

said charge display unit comprising a running cost display part that displays a running cost calculated based on electric power of said battery consumed by running and an electric power cost of a charge source charging said battery.

8. The charge display unit according to claim 7, wherein

said running cost display part displays, as said running cost, a value obtained as a result of dividing, by a running distance, a value obtained by multiplying said electric power cost by electric power consumption corresponding to said charge source charging said battery.

9. The charge display unit according to claim 7, wherein

said running cost display part displays, as said running cost, a value obtained as a result of dividing a running distance by a value obtained by multiplying said electric power cost by electric power consumption corresponding to said charge source charging said battery.

10. The charge display unit according to claim 7, wherein

said running cost display part switchably displays a first value and a second value as said running cost, said first value being obtained as a result of dividing, by a running distance, a value obtained by multiplying said electric power cost by electric power consumption corresponding to said charge source charging said battery, said second value being obtained as a result of dividing a running distance by a value obtained by multiplying said electric power cost by electric power consumption corresponding to said charge source charging said battery.

11. The charge display unit according to claim 7, wherein

in a case where said battery is charged by a plurality of charge sources, said running cost display part displays an average cost of current charge electric power as said running cost, said average cost of current charge electric power being obtained as a result of dividing, by entire electric power charged in said battery, the sum of values obtained by multiplying charged amounts charged by said charge sources by said electric power costs of said charge sources, respectively.

12. The charge display unit according to claim 7, wherein

said running cost display part displays, as said running cost, an accumulated amount obtained as a result of accumulating a value obtained by multiplying said electric power cost by electric power consumption corresponding to said charge source charging said battery.

13. The charge display unit according to claim 7, wherein

said charge display unit further comprises a CO₂ emission display part that, in a case where said battery is charged by a plurality of charge sources, converts electric power consumption into the amount of CO₂ emitted at a time of running based on information about the amount of CO₂ emission of each of said plurality of charge sources, and displays the amount of CO₂ emission,

said CO₂ emission display part displays, as said amount of CO₂ emitted at a time of running, a value obtained as a result of dividing, by a running distance, a value obtained by multiplying electric power consumption corresponding to said charge source charging said battery by the amount of CO₂ emitted per a unit amount of electric power at a time when said charge source generates electric power.
