Electric vehicle and electric vehicle control method automatically selecting power supplied to outside from engine or battery of electric vehicle
An electric vehicle is able to supply electric power to a vehicle outside and includes: an electric power generation part; an electric power storage part; and a control part that performs control such that electric power supplied from the electric power generation part or electric power supplied from the electric power storage part is automatically selected on a vehicle side in response to information obtained from an electric power supply target apparatus at the vehicle outside, and an electric power supply to the electric power supply target apparatus is performed.
1. An electric vehicle that is able to supply electric power to an outside of a vehicle, the electric vehicle comprising:
an electric power generation part;
an electric power storage part; and
a control part that performs control such that electric power supplied from the electric power generation part or electric power supplied from the electric power storage part is automatically selected on a vehicle side in response to information obtained from an electric power supply target apparatus at the outside of the vehicle, and an electric power supply to the electric power supply target apparatus is performed, wherein the vehicle and the electric power supply target apparatus perform an information exchange before starting charging/discharging,
the exchanged information are information regarding the vehicle and information regarding the electric power supply target apparatus,
the control part starts a current input/output process with the electric power supply target apparatus based on the information; determines whether the information regarding the electric power supply target apparatus is present or absent based on the exchanged information before starting charging/discharging, determines a type of the information regarding the electric power supply target apparatus when the information regarding the electric power supply target apparatus is present, and determines whether the electric power supply target apparatus deals with discharging or does not deal with discharging; and determines, based on a determination result, whether a charging control is performed, an electric vehicle electric supply mode in which an operation of the electric power generation part is stopped and the electric power stored by the electric power storage part is supplied to the electric power supply target apparatus is performed, or an engine electric supply mode in which the electric power generation part is operated and the electric power generated by the electric power generation part and the electric power stored by the electric power storage part are supplied to the electric power supply target apparatus is performed, and performs a control.
2. The electric vehicle according to claim 1 ,
wherein the electric power generation part is an engine, and the electric power storage part is a battery.
3. The electric vehicle according to claim 2 ,
wherein the control part selects an electric power supply of electric power generation by an engine which is the electric power generation part in a case where the electric power supply target apparatus is a movable electric power converter.
4. The electric vehicle according to claim 2 ,
wherein the control part switches to an electric power supply by a battery which is the electric power storage part and continues an electric supply in a case where electric power generation fails during an electric supply of electric power generation by an engine which is the electric power generation part.
5. The electric vehicle according to claim 2 ,
wherein the control part automatically switches an electric power supply by electric power generation of an engine which is the electric power generation part to an electric power supply by a battery which is the electric power storage part and performs an electric supply in a case where a remaining gasoline amount becomes a predetermined remaining amount.
6. The electric vehicle according to claim 1 ,
wherein the control part selects an electric power supply from the electric power storage part in a case where the electric power supply target apparatus is other than a movable electric power converter.
7. The electric vehicle according to claim 1 ,
wherein the control part selects an electric power supply from the electric power storage part in a case where the electric power supply target apparatus is provided in a home.
8. The electric vehicle according to claim 1 ,
wherein the control part selects an electric power supply from the electric power storage part in a case where an electric supply is performed at a place where idling is regulated based on information obtained from the electric power supply target apparatus or position information of the electric vehicle.
9. An electric vehicle control method in an electric vehicle that includes an electric power generation part and an electric power storage part and that is able to supply electric power to an outside of a vehicle, the electric vehicle control method including:
a step in which a control part performs control such that electric power supplied from the electric power generation part or electric power supplied from the electric power storage part is automatically selected on a vehicle side in response to information obtained from an electric power supply target apparatus at the outside of the vehicle, and an electric power supply to the electric power supply target apparatus is performed;
a step in which the vehicle and the electric power supply target apparatus perform an information exchange before starting charging/discharging, wherein the exchanged information are information regarding the vehicle and information regarding the electric power supply target apparatus;
a step in which the control part starts a current input/output process with the electric power supply target apparatus based on the information;
a step in which the control part determines whether the information regarding the electric power supply target apparatus is present or absent based on the exchanged information before starting charging/discharging, determines a type of the information regarding the electric power supply target apparatus when the information regarding the electric power supply target apparatus is present, and determines whether the electric power supply target apparatus deals with discharging or does not deal with discharging; and
a step in which the control part determines, based on a determination result, whether a charging control is performed, an electric vehicle electric supply mode in which an operation of the electric power generation part is stopped and the electric power stored by the electric power storage part is supplied to the electric power supply target apparatus is performed, or an engine electric supply mode in which the electric power generation part is operated and the electric power generated by the electric power generation part and the electric power stored by the electric power storage part are supplied to the electric power supply target apparatus is performed, and performs a control.
