Abstract

A vehicular charging part layout structure includes a battery case provided at a lower position of a vehicle, a battery accommodated in the battery case, and an electrical power receiving device configured to receive electrical power from the outside of the vehicle, and transmit the electrical power to the battery through a charger. The battery case includes a battery accommodation portion configured to accommodate the battery, and a charger accommodation portion configured to accommodate the charger. The battery accommodation portion and the charger accommodation portion are formed integrally.

Claims

1. A vehicular charging part layout structure comprising:

a battery case provided at a lower position of a vehicle;

a battery accommodated in the battery case; and

an electrical power receiving device configured to receive electrical power from outside of the vehicle, and transmit electrical power to the battery through a charger,

wherein the battery case includes a battery accommodation portion configured to accommodate the battery, and a charger accommodation portion configured to accommodate the charger, and

wherein the battery accommodation portion and the charger accommodation portion are formed integrally.

2. The vehicular charging part layout structure according to claim 1, wherein the charger is provided on one side of the battery in a traveling direction of the vehicle;

and

the charger accommodation portion is expanded from the battery accommodation portion toward one side in the traveling direction of the vehicle to have a protruded shape in a plan view.

3. The vehicular charging part layout structure according to claim 2, wherein a bottom surface of the charger accommodation portion is positioned above a bottom surface of the battery accommodation portion.

4. The vehicular charging part layout structure according to claim 3,

wherein the electrical power receiving device includes a non-contact electrical power receiving unit as a part of a secondary side circuit of a non-contact charging system;

a lower surface of the charger accommodation portion is positioned above a lower surface of the battery accommodation portion to form a recess recessed upward, at a lower position of the battery case; and

the non-contact electrical power receiving unit is provided in the recess.

5. The vehicular charging part layout structure according to claim 4, wherein the charger is attached to a bracket member configured to sandwich a water jacket made of metal, from upper and lower sides;

the battery and the charger are connected together by a DC cable; and

a connection terminal of the DC cable for connection with the charger is connected to a charger component part of the charger positioned above the water jacket.

6. The vehicular charging part layout structure according to claim 1, wherein the battery case is provided at a position surrounded by side frames of the vehicle.

7. The vehicular charging part layout structure according to claim 1, wherein a first accommodation chamber is provided in the battery accommodation portion, and a second accommodation chamber is provided in the charger accommodation portion;

and

the first accommodation chamber and the second accommodation chamber are connected together to form a single space.

8. The vehicular charging part layout structure according to claim 7,

wherein the battery and the charger are electrically connected through the DC cable in the battery case.

9. The vehicular charging part layout structure according to claim 7,

wherein a cooling circuit is provided in the battery case;

the cooling circuit includes a battery water jacket made of metal and configured to cool the battery, and a charger water jacket made of metal and configured to cool the charger; and

the battery water jacket and the charger water jacket are connected through an intermediate pipe in the battery case.

10. The vehicular charging part layout structure according to claim 9,

wherein the battery water jacket is larger than the charger water jacket in a plan view;

and

the battery water jacket and the charger water jacket are configured to allow a coolant to flow through the battery water jacket, and then, flow through the charger water jacket.

11. The vehicular charging part layout structure according to claim 1,

wherein the charger is attached to an upper bracket member and a lower bracket member configured to sandwich a charger water jacket made of metal, from upper and lower sides in the battery case;

the charger includes a first charger component part and a second charger component part;

the first charger component part is attached to the upper bracket member; and

the second charger component part is attached to the lower bracket member.

12. The vehicular charging part layout structure according to claim 11,

wherein a first through hole is formed in the upper bracket member, and the first charger component part is inserted into the first through hole and contacts an upper surface of the charger water jacket;

and

a second through hole is formed in the lower bracket member, and the second charger component part is inserted into the second through hole and contacts a lower surface of the charger water jacket.
