## Abstract

An automobile includes: a controller for controlling a motor; a main battery for supplying electric power to the motor via the controller; a normally open relay interposed in an electric power supply path extending from the main battery to the controller; and a sub-battery for supplying the electric power to the relay. The controller is mounted with a terminal cover that covers an output terminal for connection with a power supply cable to the motor. The sub-battery is disposed adjacent to the controller so as to interfere with the removal of the terminal cover by a worker.

## Claims

### Claim 1

An automobile comprising:
a controller configured to control a motor for driving the automobile;
a main battery configured to supply electric power to the motor via the controller:
a relay interposed in an electric power supply path extending from the main battery to the controller, the relay configured to be normally open; and
a sub-battery configured to supply electric power to the relay, the controller is provided with an input terminal that connects with a power supply cable from the main battery or an output terminal that connects with a power supply cable to the motor, the controller mounted with a terminal cover that covers the input terminal or the output terminal, and the sub-battery disposed adjacent to the controller to interfere with a removal of the terminal cover.

### Claim 2 (depends on 1)

The automobile according to claim 1, wherein
the sub-battery is disposed so as to overlap with a fastening member that fixes the terminal cover to the controller.

### Claim 3 (depends on 1)

The automobile according to claim 1, further comprising
a protector covering the terminal cover,
wherein the sub-battery is disposed adjacent to the controller to interfere with a removal of the protector.

### Claim 4 (depends on 1)

The automobile according to claim 1, wherein
the controller is fixed to a drive train, and
the sub-battery is fixed to a frame of the automobile.

### Claim 5 (depends on 1)

The automobile according to claim 1, wherein
the sub-battery is disposed on one side of a drive train and an engine is disposed on the opposite side of the drive train.

### Claim 6 (depends on 1)

The automobile according to claim 1, further comprising
an interlock circuit in which the relay is turned off by a removal of the sub-battery,
wherein the interlock circuit is configured to turn off the relay upon detection of an abnormality of a drive power source for the automobile.
