Abstract

A vehicle component mounting structure is provided with a vehicle body, a battery, a charger, a high-power electrical component other than the charger. The battery is mounted on the vehicle body. The charger is mounted on the vehicle body and converts a lower-voltage electric power supplied thereto from an external source into a higher-voltage electric power that is supplied to the battery. The high-power electrical component is mounted on the vehicle body with high voltage being supplied to the high-power electrical component. The charger and the high-power electrical component are arranged on longitudinally opposite sides of the battery with respect to a longitudinal direction of the vehicle body.

Claims

1. A vehicle component mounting structure comprising:

a vehicle body;

a battery mounted on the vehicle body;

a charger mounted on the vehicle body that converts a lower-voltage electric power supplied thereto from an external source into a higher-voltage electric power that is supplied to the battery; and

a high-power electrical component other than the charger mounted on the vehicle body with high voltage being supplied to the high-power electrical component,

the charger and the high-power electrical component being arranged on longitudinally opposite sides of the battery with respect to a longitudinal direction of the vehicle body.

2. The vehicle component mounting structure as recited in claim 1, further comprising

an electric charging port electrically connected to the charger to supply electric power from the external source to the charger, the electric charging port being positioned closer to the high-power electrical component than to the charger.

3. The vehicle component mounting structure as recited in claim 2, wherein

the high-power electrical component is arranged farther frontward than the charger with respect to the longitudinal direction of the vehicle body, and the charging port is arranged on a frontward portion of the vehicle body.

4. The vehicle component mounting structure as recited in claim 2, further comprising

a first charging harness electrically connecting the battery to the high-power electrical component;

a second charging harness electrically connecting the first charging harness to the charger; and

a relay operatively arranged with respect to the second charging harness with the relay being arranged to switch the second harness between a state of being connected to the first charging harness and a state of being disconnected from the first charging harness.

5. The vehicle component mounting structure as recited in claim 2, wherein

the electric charging port includes a low-voltage charging port electrically connected to the charger by a low-voltage harness and a high-voltage charging port electrically connected to the high-power electrical component.

6. The vehicle component mounting structure as recited in claim 5, wherein

the high-power electrical component includes a circuit box that is arranged closer to the electric charging port than to the charger.

7. The vehicle component mounting structure as recited in claim 6, wherein

the circuit box is electrically connected to the charger by a first high-voltage harness, electrically connected to the high-voltage charging port by a second high-voltage harness, and electrically connected to the battery by a third high-voltage harness.

8. The vehicle component mounting structure as recited in claim 6, wherein

the battery is arranged closer to the circuit box than to the charger.

9. The vehicle component mounting structure as recited in claim 6, wherein

the battery is arranged between the circuit box and the charger.

10. The vehicle component mounting structure as recited in claim 6, wherein

the electric charging port is arranged on a frontward portion of the vehicle body, with the circuit box being disposed inside a front compartment formed in a frontward portion of the vehicle body, and the battery and the charger being arranged rearward of the circuit box.

11. The vehicle component mounting structure as recited in claim 1, wherein

the battery including a plurality of individual batteries arranged as a single unit.

12. The vehicle component mounting structure as recited in claim 2, further comprising

a first charging harness electrically connecting the battery to the high-power electrical component;

a second charging harness electrically connecting the first charging harness to the charger; and

a relay operatively arranged with respect to the second charging harness with the relay being arranged to switch the second harness between a state of being connected to the first charging harness and a state of being disconnected from the first charging harness.

13. The vehicle component mounting structure as recited in claim 7, wherein

the battery is arranged closer to the circuit box than to the charger.

14. The vehicle component mounting structure as recited in claim 7, wherein

the battery is arranged between the circuit box and the charger.

15. The vehicle component mounting structure as recited in claim 8, wherein

the battery is arranged between the circuit box and the charger.

16. The vehicle component mounting structure as recited in any one of claim 7, wherein

the electric charging port is arranged on a frontward portion of the vehicle body, with the circuit box being disposed inside a front compartment formed in a frontward portion of the vehicle body, and the battery and the charger being arranged rearward of the circuit box.

17. The vehicle component mounting structure as recited in any one of claim 8, wherein

the electric charging port is arranged on a frontward portion of the vehicle body, with the circuit box being disposed inside a front compartment formed in a frontward portion of the vehicle body, and the battery and the charger being arranged rearward of the circuit box.

18. The vehicle component mounting structure as recited in any one of claim 9, wherein

the electric charging port is arranged on a frontward portion of the vehicle body, with the circuit box being disposed inside a front compartment formed in a frontward portion of the vehicle body, and the battery and the charger being arranged rearward of the circuit box.
