Abstract

There is provided an electric vehicle including: a battery that is accommodated beneath a floor of an in-vehicle space portion; a temperature-adjustable storage unit that is accommodated in the in-vehicle space portion; a driving unit that is provided at a vehicle longitudinal direction one side of the battery; an electric power converter for driving that is disposed, in a vehicle longitudinal direction, disposed within a range that extends from the battery to an end portion of a vehicle longitudinal direction outer side of the driving unit, and that is electrically connected to the battery and the driving unit; an electric power converter for the storage unit that is disposed within the range and that is electrically connected to the storage unit; and a control unit that controls autonomous driving of the vehicle.

First claim

What is claimed is:

1 . An electric vehicle comprising:
a battery that is accommodated beneath a floor of an in-vehicle space portion; a temperature-adjustable storage unit that is accommodated in the in-vehicle space portion; a driving unit that is provided at a vehicle longitudinal direction one side of the battery; an electric power converter for driving that is disposed, in a vehicle longitudinal direction, disposed within a range that extends from the battery to an end portion of a vehicle longitudinal direction outer side of the driving unit, and that is electrically connected to the battery and the driving unit; an electric power converter for the storage unit that is disposed within the range and that is electrically connected to the storage unit; and a control unit that controls autonomous driving of the vehicle.

2 . The electric vehicle of claim 1 , wherein the control unit is disposed at a vehicle longitudinal direction another side of the battery.

3 . The electric vehicle of claim 1 , further comprising a branch box that is electrically connected to the battery, and that branches electric power of the battery between the electric power converter for driving and the electric power converter for the storage unit.

4 . The electric vehicle of claim 1 , further comprising:
an opening that is provided in a vehicle transverse direction wall portion at the in-vehicle space portion, and through which cargo can be loaded and unloaded; and a ramp that can be accommodated between the battery and a floor surface of the in-vehicle space portion, and that, at the opening portion, extends from the floor surface toward an exterior of the in-vehicle space portion.

5 . The electric vehicle of claim 4 , wherein:
the opening portion includes a front opening portion that is at a vehicle front side and a rear opening portion that is at a vehicle rear side, and the ramp includes: a front ramp that is set for the front opening portion in a state of usage, and that is accommodated beneath the floor, and a rear ramp that is set for the rear opening portion in a state of usage, and that is accommodated beneath the floor so as to be apart from the front ramp as seen in a plan view.

6 . The electric vehicle of claim 5 , wherein:
the in-vehicle space portion includes a normal temperature room that is a space at which temperature adjustment is not carried out, the front opening portion is an entrance to either of the normal temperature room or an equipment room in which the storage unit is accommodated, and the rear opening portion is an entrance to another of the normal temperature room or the equipment room.

7 . The electric vehicle of claim 1 , wherein:
the in-vehicle space portion includes a normal temperature room that is a space at which temperature adjustment is not carried out, and the storage unit is disposed in the in-vehicle space portion further toward the driving unit side than the normal temperature room.

8 . The electric vehicle of claim 6 , wherein the normal temperature room has a height such that a worker can stand therein.
