Abstract

A vehicle includes a vehicle interior, a battery provided below the vehicle interior with a floor panel in between, a front room provided in front of the vehicle interior with a dashboard in between, a charging port disposed in the front room, and a junction box which electrically connects a first power line extending from the charging port and a second power line extending from a power line connection portion of the battery. The junction box is disposed on a virtual line connecting the charging port and the power line connection portion in a side view.

First claim

The invention claimed is:

1. A vehicle comprising:
a vehicle interior;
a battery provided below the vehicle interior with a floor panel therebetween;
a front room provided in front of the vehicle interior with a dashboard therebetween;
a charging port disposed in the front room; and
a junction box electrically connecting a first power line extending from the charging port and a second power line extending from a power line connection portion of the battery, wherein
the junction box is disposed on a virtual line connecting the charging port and the power line connection portion in a side view,
the junction box, a charger connected to the charging port via a third power line, and a DC-DC converter are disposed in the front room,
the junction box is disposed above the charger and the DC-DC converter, and
the second power line is disposed along the virtual line in a side view.

2. The vehicle according to claim 1 , wherein the first power line and the second power line are DC lines.

3. The vehicle according to claim 1 , wherein
one end portion of the second power line is connected to the power line connection portion from the front side, and
the other end portion of the second power line is connected to the second power line connection portion of the junction box from a vehicle width direction.

4. The vehicle according to claim 1 , wherein
the charging port is disposed in a charging port accommodating portion including a charging case and a charging lid, and
the second power line is disposed in a rear side of the charging port accommodation portion in a front-rear direction of the vehicle, within a width of the charging port accommodation portion in the vehicle width direction, and below a rear end portion of the charging port accommodation portion in a height direction of the vehicle.

5. The vehicle according to claim 4 , wherein the charging port accommodation portion is disposed so as to overlap with a bulkhead constituting a front end portion of the vehicle in a top view.

6. The vehicle according to claim 4 , wherein an opening width of a space formed in the rear side of the charging port accommodation portion in the front-rear direction is shorter than a width of the charging port accommodation portion in an open state of a front hood covering the front room.

7. The vehicle according to claim 1 , further comprising:
a driving device unit which is disposed in the rear side of the battery, and receives electric power from the battery to drive the vehicle, and
a fourth power line connecting the junction box and the driving device unit,
wherein a combined length of the first power line and the second power line is shorter than a combined length of the second power line and the fourth power line.

8. The vehicle according to claim 7 , wherein the second power line and the fourth power line are disposed adjacent to each other in the front room.
