Abstract

An electricity supply vehicle is provided with an electricity storage device charged with generated energy of an electric generator driven by an internal combustion engine mounted on the electricity supply vehicle or with regenerated energy of the electricity supply vehicle and is operable to supply electricity to an external equipment located outside of the electricity supply vehicle during stop of the electricity supply vehicle. The electricity supply vehicle includes: a setting unit configured to set expected supply electric energy to be supplied to the external equipment; and a determining unit configured to determine, based on the expected supply electric energy, a target charging amount of the electricity storage device to be charged during running of the electricity supply vehicle.

Claims

1. An electricity supply vehicle that is provided with an electricity storage device charged with generated energy of an electric generator driven by an internal combustion engine mounted on the electricity supply vehicle or with regenerated energy of the electricity supply vehicle and that is operable to supply electricity to an external equipment located outside of the electricity supply vehicle during stop of the electricity supply vehicle, the electricity supply vehicle comprising:

a setting unit configured to set expected supply electric energy to be supplied to the external equipment; and

a determining unit configured to determine, based on the expected supply electric energy, a target charging amount of the electricity storage device to be charged during running of the electricity supply vehicle.

2. The electricity supply vehicle according to claim 1, further comprising:

an electric motor capable of being driven with electricity supplied from the electricity storage device; and

a judging unit configured to judge, based on a remaining charging amount of the electricity storage device, whether running by a driving force obtained from the electric motor is to be permitted, wherein

when the remaining charging amount exceeds the target charging amount, the judging unit permits the running by the driving force obtained from the electric motor.

3. The electricity supply vehicle according to claim 1, wherein the setting unit includes:

a selecting unit configured to select the external equipment; and

a calculating unit configured to calculate the expected supply electric energy based on information related to the external equipment selected by the selecting unit.

4. The electricity supply vehicle according to claim 1, further comprising:

an electric motor capable of being driven with electricity supplied from the electricity storage device; and

a judging unit configured to judge, based on a remaining charging amount of the electricity storage device, whether running by a driving force obtained from the electric motor is to be permitted,

wherein, when the remaining charging amount exceeds the target charging amount, the judging unit permits the running by the driving force obtained from the electric motor, and

wherein the setting unit includes;

a selecting unit configured to select the external equipment; and

a calculating unit configured to calculate the expected supply electric energy based on information related to the external equipment selected by the selecting unit.

5. The electricity supply vehicle according to claim 3, wherein the setting unit includes an input unit configured to input usage time of the external equipment selected by the selecting unit.

6. The electricity supply vehicle according to claim 1, further comprising:

an electric motor capable of being driven with electricity supplied from the electricity storage device; and

a judging unit configured to judge, based on a remaining charging amount of the electricity storage device, whether running by a driving force obtained from the electric motor is to be permitted,

wherein, when the remaining charging amount exceeds the target charging amount, the judging unit permits the running by the driving force obtained from the electric motor,

wherein the setting unit includes;

a selecting unit configured to select the external equipment; and

a calculating unit configured to calculate the expected supply electric energy based on information related to the external equipment selected by the selecting unit, and

wherein the setting unit includes an input unit configured to input usage time of the external equipment selected by the selecting unit.

7. The electricity supply vehicle according to claim 1, wherein the electricity storage device is capable of being charged also with electricity supplied from an external electricity source.

8. The electricity supply vehicle according to claim 1, further comprising a conversion apparatus configured to convert electricity charged in the electricity storage device into electricity to be supplied to the external equipment.

9. The electricity supply vehicle according to claim 1, wherein

the target charging amount of the electricity storage device to be charged during the running is a first target charging rate in a case that the external equipment is used, and

the first target charging rate is determined by adding a second target charging rate of the electricity storage device in a case that use of the external equipment is not expected to a percentage of the expected supply electric energy to an electricity storage capacity of the electricity storage device.
