Abstract

An electric vehicle wherein at least part of a cell unit is provided along an inclined part of a rear dividing wall. A bottom end of the cell unit is positioned lower than the hip point of a passenger. As seen from the vehicle-width direction, motor mounts are positioned so that the top part of the cell unit and part of the motor mounts overlap in the vertical direction of the electric vehicle.

Claims

1. An electric vehicle having two seats, including a battery unit, a motor configured to drive a rear wheel, and motor mounts disposed behind the battery unit and supporting the motor securely in place, the electric vehicle further comprising:

a rear partition defining a passenger compartment behind a rear surface of an occupant seat, wherein;

the rear partition includes a slanted portion, which is inclined progressively rearward of the electric vehicle in an upward direction;

the battery unit has at least a portion disposed along the slanted portion of the rear partition;

the battery unit has a lower end disposed below a hip point of an occupant; and

the motor mounts are disposed such that an upper portion of the battery unit and a portion of the motor mounts overlap each other in a vertical direction of the electric vehicle as viewed transversely across the electric vehicle;

the upper portion of the battery unit is positioned more rearwardly than a lower portion of the battery unit in a longitudinal direction of the electric vehicle;

in space that is created below the upper portion of the battery unit and behind the lower portion of the battery unit, a portion of the motor mounts is disposed; and

the portion of the motor mounts is located below the hip point.

2. The electric vehicle according to claim 1, wherein:

the battery unit is disposed outside of the passenger compartment; and

the battery unit has a portion fixed to the rear partition.

3. The electric vehicle according to claim 1, wherein:

the battery unit supplies electric power to the motor; and

the battery unit, the motor, and an inverter configured to control supply of electric power from the battery unit to the motor are disposed in one space.

4. The electric vehicle according to claim 3, wherein the inverter is disposed behind the battery unit and above the motor.

5. The electric vehicle according to claim 3, wherein the battery unit is constructed integrally with the inverter.

6. The electric vehicle according to claim 5, wherein the battery unit includes a cover, the cover being installed in a direction that is the same as a direction in which the inverter is installed.
